    This study was conducted to compare the quality of life (QOL) in patients with neurogenic intermittent claudication (NIC) secondary to lumbar spinal stenosis (LSS). Using the 36-Item Short Form (SF-36) questionnaire, the authors compared the results obtained in patients treated with the X STOP Interspinous Process Decompression (IPD) System with those obtained in patients who underwent nonoperative therapies. Patients with LSS were enrolled in a prospective 2-year multicenter study and randomized either to the X STOP or nonoperative group. The SF-36 survey was used to assess the QOL before treatment and at 6 weeks, 6 months, 1 year, and 2 years posttreatment. An analysis of variance was used to compare individual pre- and posttreatment mean SF-36 domain scores between the two groups and within each treatment group. At all posttreatment time points, the authors observed the following: (1) mean domain scores in X STOP-treated patients were significantly greater than those in patients treated nonoperatively, with the exception of the mean General Health (GH), Role Emotional, and Mental Component Summary scores at 2 years; and (2) mean posttreatment domain scores documented in X STOP-treated patients were significantly greater than mean pretreatment scores, with the exception of mean GH scores at 6, 12, and 24 months. The results of this study demonstrate that the X STOP device is significantly more effective than nonoperative therapy in improving the QOL in patients with LSS. The results are comparable with those reported in other studies involving traditional decompressive techniques for LSS and suggest that the X STOP implant can provide an effective treatment compared with nonoperative and conventional surgical therapies.

    To evaluate the inflammatory involvement of lumbar interspinous bursae in patients with polymyalgia rheumatica (PMR) using magnetic resonance imaging (MRI). Ten consecutive, untreated new patients with PMR and pain in the shoulder and pelvic girdles were investigated. Seven patients with spondyloarthritis (4 with psoriatic spondyloarthrits, one with entheropatic spondyloarthritis, and 2 with ankylosing spondylitis) as well as 2 patients with spinal osteoarthritis and 2 patients with rheumatoid arthritis with lumbar pain served as controls. MRI of lumbar spine was performed in all PMR patients and controls. Nine patients (5 PMR patients and 4 controls) also had MRI of the thoracic spine. MRI evidence of interspinous lumbar bursitis was found in 9/10 patients with PMR and in 5/11 controls. A moderate to marked (grade ≥2 on a semiquantitative 0-3 scale) lumbar bursitis occurred significantly more frequently in patients with PMR than in control patients (60% vs. 9%, p=0.020). In most of the patients and controls lumbar bursitis was found at the L3-L5 interspaces. Only 2 patients had bursitis at a different level (one patient had widespread lumbar bursitis, and one control at L2-L4). No interspinous bursitis was demonstrated by MRI of the thoracic spine in patients and controls. Inflammation of lumbar bursae may be responsible for the low back pain reported by patients with PMR. The prominent inflammatory involvement of bursae including those of the lumbar spine supports the hypothesis that PMR may be a disorder affecting predominantly extra-articular synovial structures.

    Objective: To explore the mid- to long-term effect of Wallis interspinous dynamic stabilization system on the adjacent segment degeneration. Methods: From March 2009 to June 2010, in Department of Orthopedics, Beijing Luhe Hospital, Capital Medical University, 24 patients with L 4-5 monosegmental lumbar disc herniation were treated with posterior lumbar decompression combined with Wallis interspinous dynamic fixation. Clinical outcomes were evaluated with visual analogue score (VAS) (back pain), VAS (leg pain) and oswestry disability index (ODI) score. Intervertebral disc height (IDH) and range of motion (ROM) of the upper and lower adjacent segments were measured on X-ray. The degneration of lumbar intervertebral disc was evaluated on MRI. paired- t test was used to compare preoperative VAS, ODI, IDH, ROM and the degeneration of lumbar intervertebral disc with those at the final follow-up. Results: Twenty patients had a mean follow-up time of (65.2±4.7) months. At the final follow-up, VAS (back pain), VAS (leg pain) and ODI showed significant improvement (all P 0.05); ROM of the upper adjacent segment increased ( P 0.05). The degeneration of intervertebral discs at the upper and lower segments showed no significant changes at the final follow-up ( P >0.05). Conclusions: Posterior decompression combined with Wallis interspinous dynamic stabilization system for monosegmental lumbar disc herniation can achieve satisfactory clinical results. More than five years' follow-up confirmed that the Wallis system will not accelerate adjacent segment degeneration.

    Lumbar lateral shift (LLS) is a common clinical observation but has rarely been described in a patient with a history of lumbar surgery. The purpose of the current case report was to describe the use of the McKenzie Method of Mechanical Diagnosis and Therapy (MDT) in the multi-modal treatment of a patient with an LLS and a history of multiple surgical procedures in the lumbar spine, including interspinous process device (IPD) implantation. A 72-year-old female with chronic low back pain (LBP) and a surgical history in the lumbar spine was referred to physical therapy for radiating leg pain and presented with a right LLS. Her chief complaints included sitting for long periods, vacuuming and ascending stairs into her home. The patient was treated during eight visits over 30 days. Treatment interventions included manual shift correction, self-correction and management, joint mobilisation below the level of IPD implantation ,neurophysiology education, and development of a home exercise programme. At discharge, her leg pain was resolved and all goals had been met. The patient reported maintenance of gains at 6-month follow-up. Utilisation of the MDT approach, including LLS correction, produced positive outcomes in a complex patient with previous IPD implantation. Future research should investigate treatment and outcomes after invasive spinal procedures in similar patient populations to better inform clinical management. 4.

    [Purpose] The intra- and inter-examiner reliabilities of lumbar interspinous process distances measured by ultrasound imaging were examined. [Subjects and Methods] The subjects were 10 males who had no history of orthopedic diseases or dysfunctions. Ten lumbar interspinous images from 360 images captured from 10 subjects were selected. The 10 images were measured by nine examiners. The lumbar interspinous process distance measurements were performed five times by each examiner. In addition, four of the nine examiners measured the distances again after 4 days for test-retest analysis. In statistical analysis, the intraclass correlation coefficient was used to investigate relative reliability, and Bland-Altman analysis was used to investigate absolute reliability. [Results] The intraclass correlation coefficients (1, 1) for intra-examiner reliability ranged from 0.985 to 0.998. For inter-rater reliability, the intraclass correlation coefficient (2, 1) was 0.969. The intraclass correlation coefficients (1, 2) for test-retest reliability ranged from 0.991 to 0.999. The Bland-Altman analysis results indicated no systematic error. [Conclusion] The results indicate that ultrasound measurements of interspinous process distance are highly reliable even when measured only once by a single person.

    Lumbar herniated disks result in lumbar pain with neurologic involvement. Medical treatment and rehabilitation provide improvement for this type of lumbar pain at the early stages. When conservative treatment fails, the surgical option offers the possibility of improving patients' health status. Moojen considers that the application of interspinous spacers provides good results. The purpose of this research is to assess the clinical and imaging results in patients with contained lumbar herniated disk treated with the DYNAMIC INTERSPACER interspinous spacer, a Mexican product. The efficacy of the interspinous device was assessed by means of a near-investigational and longitudinal study conducted at "General Ignacio Zaragoza" ISSSTE Regional Hospital in patients with a diagnosis of lumbar pain. The mean age of the sample is 46.1 years, with an age range of 26-55 years. The treated levels were 6 L5-S1 and 5 L4-L5; two levels were treated in two patients. The mean preoperative VAS score was 8.1. The mean VAS score at postoperative year three was 1.6. Multiple types and brands of foreign interspinous devices are applied in Mexico which results in patients' clinical improvement. We proved that the use of the Mexican interspinous device can clinically improve patients with lumbar pain due to herniated disk. A decrease in the compression of the sac or the nerve roots by the hernia was observed in the comparative preoperative and postoperative MRI images.

    Posterior lumbar interbody fusion (PLIF) and internal fixation are commonly performed for the treatment of lower back pain due to lumbar spinal degeneration. We have developed a novel interspinous fixation device, the interspinous fastener (ISF) for potential use in the surgical management of degenerative spinal disease. The aim of this study was to assess the in vitro biomechanical characteristics of calf lumbar spine specimens after ISF fixation with modified PLIF. Ten lumbar spine (L3-L6) specimens from ten fresh calf cadavers (8-10 weeks of age) were used. Each specimen underwent sequential testing for each of the following four groups: no instrumentation (INTACT); interspinous fusion device fixation + PLIF (ISF); unilateral pedicle screw and titanium rod fixation + PLIF (UPS); bilateral pedicle screw and titanium rod fixation + PLIF (BPS). Outcome measures included angular range of motion (ROM) during unloaded and loaded (8 Nm) flexion, extension, left bending, right bending, left torsion and right torsion. For all unloaded and loaded assessments, ROM was significantly higher in the INTACT group compared with all other groups (P < 0.05). Similarly, ROM was significantly higher in the UPS group (indicating decreased stability) compared with the ISF and BPS groups (P < 0.05). The only significant difference between the ISF and BPS groups was in the ROM with unloaded extension (higher in the BPS group, P = 0.006). We found that ISF fixation with PLIF of the lower lumbar spine provided biomechanical stability that was equivalent to that associated with bilateral pedicle screw/rod fixation with PLIF. The ISF shows potential as an alternative means of fixation in the surgical management of degenerative spinal disease.

    Pedicle screw fixation may induce abnormal activity at adjacent segment and accelerate the degeneration of lumbar vertebrae. Dynamic stabilizers could provide an intermediate solution between conservative treatment and fusion surgery. Lumbar vertebral segment cephalad to instrumented fixation was the most common localization of adjacent segment degeneration. The aim of this study is to explore the use of interspinous process devices in the lumbar vertebral segment cephalad to fixation segment in changing the mechanical distribution and limiting abnormal activity of the spine. Eight specimens were tested in the following groups: intact group, instability group (bilateral facetectomy at L3-L4), fixation group (bilateral facetectomy and pedicle screw fixation at L3-L4), and hybrid fixation group (fixation at L3-L4 and simulating interspinous device implantation of 6, 8, 10, 12, 14, 16, and 18 mm at L2-L3). Range of motion, motion of vertebral body, and strain distribution change were recorded. The range of motion in extension with 16- and 18-mm hybrid constructs was significantly lower than intact, instability, and fixation groups. In flexion and lateral bending, the strain values of L4 inferior articular process with 18-mm hybrid construct have a significant difference compared with other groups. In axial rotation, under the condition of a contralateral state, the strain values of L2 superior articular process with 18-mm hybrid construct have a significant difference compared with intact and fixation groups. The strain value of the L4 inferior articular process had negative correlation with height distraction in three dimensions, except extension. A negative correlation between the strain value of the L2 superior articular process and distraction height was found in contralateral bending and contralateral axial rotation. Interspinous process devices above the fixation segment can change the mechanical distribution of the spine and limit activity in some of the

    Lumbar spondylolisthesis (LS) and lumbar instability (LI) are common disorders in patients with low back or lumbar radicular pain. However, few physical examination tests for LS and LI have been reported. In the study described herein, new physical examination tests for LS and LI were devised and evaluated for their validity. The test for LS was designated "low midline sill sign", and that for LI was designated "interspinous gap change" during lumbar flexion-extension motion. The validity of the low midline sill sign was evaluated in 96 patients with low back or lumbar radicular pain. Validity of the interspinous gap change during lumbar flexion-extension motion was evaluated in 73 patients with low back or lumbar radicular pain. The sensitivity, specificity, and positive and negative predictive values of the two tests were also investigated. The sensitivity and specificity of the low midline sill sign for LS were 81.3% and 89.1%, respectively. Positive and negative predictive values of the test were 78.8% and 90.5%, respectively. The sensitivity and specificity of the interspinous gap change test for LI were 82.2% and 60.7%, respectively. Positive and negative predictive values of the test were 77.1% and 68.0%, respectively. The low midline sill sign and interspinous gap change tests are effective for the detection of LS and LI, and can be performed easily in an outpatient setting.

    Objective: This study was designed to evaluate the feasibility of the implantation of a new interspinous device (Falena) in patients with lumbar spinal stenosis. The clinical outcomes and imaging results were assessed by orthostatic MR during an up to 6-month follow-up period. Methods: Between October 2008 and February 2010, the Falena was implanted at a single level in 26 patients (17 men; mean age, 69 (range, 54–82) years) who were affected by degenerative lumbar spinal stenosis. All of the patients were clinically evaluated before the procedure and at 1 and 3 months. Furthermore, 20 patients have completed a 6-month follow-up. Pain was assessed before and after the intervention using the Visual Analogue Scale score and the Oswestry Disability Index questionnaire. Orthostatic MR imaging was performed before the implantation and at 3 months to assess the correlation with the clinical outcome. Results: The mean ODI score decreased from 48.9 before the device implantation to 31.2 at 1 month (p < 0.0001). The mean VAS score decreased from 7.6 before to 3.9 (p < 0.0001) at 1 month and 3.6 at 3 months after the procedure (p = 0.0115). These values were stable at 6 months evaluation. No postimplantation major complications were recorded. MRI evaluation documented in most cases an increased size of the spinal canal area. Similarly a bilateral foraminal area improvement was found. The variation of the intervertebral space height measured on the posterior wall was not significant. Conclusions: In our preliminary experience with the Falena in a small cohort of patients, we obtained clinical and imaging results aligned to those reported with similar interspinous devices.

    Patients suffering from neurogenic intermittent claudication secondary to lumbar spinal stenosis have historically been limited to a choice between a decompressive laminectomy with or without fusion or a regimen of non-operative therapies. The X STOP Interspinous Process Distraction System (St. Francis Medical Technologies, Concord, Calif.), a new interspinous implant for patients whose symptoms are exacerbated in extension and relieved in flexion, has been available in Europe since June 2002. This study reports the results from a prospective, randomized trial of the X STOP conducted at nine centers in the U.S. Two hundred patients were enrolled in the study and 191 were treated; 100 received the X STOP and 91 received non-operative therapy (NON OP) as a control. The Zurich Claudication Questionnaire (ZCQ) was the primary outcomes measurement. Validated for lumbar spinal stenosis patients, the ZCQ measures physical function, symptom severity, and patient satisfaction. Patients completed the ZCQ upon enrollment and at follow-up periods of 6 weeks, 6 months, and 1 year. Using the ZCQ criteria, at 6 weeks the success rate was 52% for X STOP patients and 10% for NON OP patients. At 6 months, the success rates were 52 and 9%, respectively, and at 1 year, 59 and 12%. The results of this prospective study indicate that the X STOP offers a significant improvement over non-operative therapies at 1 year with a success rate comparable to published reports for decompressive laminectomy, but with considerably lower morbidity.

    Few studies have compared the clinical and radiological outcomes between Coflex interspinous stabilization and posterior lumbar interbody fusion (PLIF) for degenerative lumbar disease. We compared the at least 5-year clinical and radiological outcomes of Coflex stabilization and PLIF for lumbar degenerative disease. Eighty-seven consecutive patients with lumbar degenerative disease were retrospectively reviewed. Forty-two patients underwent decompression and Coflex interspinous stabilization (Coflex group), 45 patients underwent decompression and PLIF (PLIF group). Clinical and radiological outcomes were evaluated. Coflex subjects experienced less blood loss, shorter hospital stays and shorter operative time than PLIF (all pdisease was higher in the PLIF group, but this did not achieve statistical significance (11.1% vs. 4.8%, p=0.277). Both groups provided sustainable improved clinical outcomes for lumbar degenerative disease through at least 5-year follow-up. The Coflex group had significantly better early efficacy than the PLIF group. Coflex interspinous implantation after decompression is safe and effective for lumbar degenerative disease.

    [Purpose] This study assessed the reliability and validity of an ultrasound-based imaging method for measuring the interspinous process distance in the lumbar spine using two different index points. [Subjects and Methods] Ten healthy males were recruited. Five physical therapy students participated in this study as examiners. The L2-L3 interspinous distance was measured from the caudal end of the L2 spinous process to the cranial end of the L3 spinous process (E-E measurement) and from the top of the L2 spinous process to the top of the L3 spinous process (T-T measurement). Intraclass correlation coefficients were calculated to estimate the relative reliability. Validity was assessed using a model resembling the living human body. [Results] The reliability study showed no difference in intra-rater reliability between the two measurements. However, the E-E measurement showed higher inter-rater reliability than the T-T measurement (Intraclass correlation coefficients: 0.914 vs. 0.725). Moreover, the E-E measurement method had good validity (Intraclass correlation coefficients: 0.999 and 95% confidence interval for minimal detectable change: 0.29 mm). [Conclusion] These results demonstrate the high reliability and validity of ultrasound-based imaging in the quantitative assessment of lumbar interspinous process distance. Of the two methods, the E-E measurement method is recommended.

    Full Text Available Introduction. Posterior Dynamic stabilization using the interspinous spacer device is a known to be used as an alternative to rigid fusion in neurogenic claudication patients in the absence of macro instability. Actually, it plays an important in the management of adjacent segment disease in previously fused lumbar spine. Materials and Method. We report our experience with posterior dynamic stabilization using an interspinous spacer. 134 cases performed in our institution between September 2008 and August 2012 with different lumbar spine pathologies. The ages of our patients were between 40 and 72 years, with a mean age of 57 years. After almost 4 years of follow up in our patient and comparing their outcome to our previous serious we found that in some case the interspinous distracter has an important role not only in the treatment of adjacent segment disease but also in its prevention. Results and Discussion. Clinical improvement was noted in ISD-treated patients, with high satisfaction rate. At first, radicular pain improves with more than 3/10 reduction of the mean score on visual analog scale (VAS. In addition, disability score as well as disc height and lordotic angle showed major improvement at 3 to 6 months post operatively. And, no adjacent segment disease was reported in the patient operated with interspinous spacer. Conclusion. The interspinous spacer is safe and efficient modality to be used not only as a treatment of adjacent segment disease but also as a preventive measure in patients necessitating rigid fusion.

    Full Text Available We present here a rare case of heterotopic ossification in interspinous/interlaminar Coflex device. The classical surgical indications for these implants are degenerative canal stenosis, discogenic low back pain, disk herniations, facet syndrome, and instability. However, fractures of spinous processes are a potential risk after interspinous/interlaminar devices’ implantation. Recently, heterotopic ossification, a well-known complication of hip and knee arthroplasty, has been reported after cervical and lumbar prosthesis. We performed undercutting and implantation of the dynamic interspinous/interlaminar device to treat an adult male patient with L4-L5 stenosis. The patient underwent 45-day imaging and clinical followup, and we observed both a neurological and imaging improvement. A CT bone scan, performed 3 years after surgery for recurrence of neurogenic claudication, showed a new stenosis due to an abnormal ossification all over the device. To our knowledge, this is the first reported case of heterotopic ossification in an interspinous/interlaminar dynamic device. Accordingly, we aim to suggest it as a new complication of interspinous/interlaminar devices.

    The aim of this study was to assess the outcome of symptomatic lumbar degenerative disease treated with topping-off technique (Coflex(™) combined with fusion) and compare two-segment fusion at mid-long term follow-up; and find out whether the topping-off technique can reduce the rate of adjacent segment degeneration (ASD) after fusion. One hundred and fifty-four consecutive patients who received topping-off surgery (76 patients) and two-segment fusion surgery (88 patients) from March 2009 to March 2012 were studied. All patients included in the analysis had a minimum of three years of follow-up. Radiographic and clinical outcomes between the two groups were compared. A logistic regression analysis was used to analyze risk factors for developing radiographic ASD. Significant differences in clinical outcomes were observed between these two groups at three post-operative years (all, p fusion surgery for the treatment of two-segment lumbar disease.

    A controversial indication of interspinous spacers is their use as a complement to discectomy. At the present time, there is no solid clinical evidence of effectiveness of that association, which might result from variability in spacer positioning, restricting its correct biomechanical actions. In this study our goal was to identify and analyse the variability in the placement of an interspinous spacer, and to investigate its relationship with the clinical results. We performed a retrospective study on X-ray films from 71 patients suffering from disc herniation in L4-L5 who underwent surgery in our hospital, consisting of: microdiscectomy and biomed interspinous spacer implantation. The geomorphometric techniques used to analyse the data were procrustes superimposition and principal components analysis. We compared the clinical results (using the Herron and Turner scale), segmental lordosis and surgical distraction with the geomorphometric parameters. Significant morphological variability was found in the implant position showing cephalo-caudal translation and clockwise-counterclockwise rotations. This variability did not correlate with clinical results. A relationship with anatomical features (lordosis) and additional surgical distraction was identified. A different morphology of implant-segment configuration was identified in cases with recurrence of disc herniation. Geometric morphometrics allowed identifying high variability in the final placement of interspinous spacers. Nevertheless, it seems not to be related to the clinical outcome, depending rather on the degree of lordosis and distraction. Some differences in segment-implant morphology were identified in cases with recurrences. To assess the effectiveness of spacers, larger studies including morphological and clinical variables are required. Copyright © 2013 Sociedad Española de Neurocirugía. Published by Elsevier España.

    The aim of the study was to investigate the changes of the lumbar intervertebral disc degeneration by magnetic resonance imaging (MRI) after the implantation of interspinous device and the fusion of the adjacent segment. A total of 62 consecutive patients suffering L5/S1 lumbar disc herniation (LDH) with concomitant disc space narrowing or low-grade instability up to 5 mm translational slip in L5/S1 level were treated with lumbar interbody fusion (LIF) via posterior approach. Thirty-four of these patients (Coflex group) received an additional implantation of the interspinous spacer device (Coflex™) in the level L4/L5, while the rest of 28 patients (fusion group) underwent the fusion surgery alone. Clinical and radiographic examinations were performed at pre- and postoperative visits to compare the clinical outcomes and the changes of the L4/L5 vertebral disc degeneration on MRI in both Coflex and fusion group. Although both Coflex and fusion group showed improvements of the clinical outcomes assessed by the Oswestry Disability Index (ODI) after surgery, patients in Coflex group had more significant amelioration (P fusion surgery could delay the disc degeneration of the adjacent segment.

    Avoiding exposure of extremities to cold combined with pharmacologic treatment usually suffice in the attempt to suppress the related symptoms of Raynaud's syndrome. This case report describes a severe case of Raynaud's syndrome affecting the lower extremities of a 16-year-old female. She was referred to a centre of vascular surgery with severe vasospasms of the feet. After failed attempts of pharmacologic treatment, a laparoscopic lumbar sympathectomy was performed with no complications and a slight reduction of symptoms three years post-surgically.

    Study Design Lumber disc arthroplasty is a technological advancement that has occurred in the last decade to treat lumbar degenerative disk diseases. Purpose The aim of this retrospective study was to establish the impact and outcomes of managing patients with lumbar degenerative disk disease who have been treated with lumbar total disc arthroplasty (TDA). Overview of Literature Several studies have shown promising results following this surgery. Methods We reviewed the files of 104 patients at the Department of Neurosurgery in Colmar (France) who had been operated on by lumbar spine arthroplasty (Prodisc) between April 2002 and October 2008. Results Among the 104 patients, 67 were female and 37 were male with an average age of 33.1 years. We followed the cases for a mean of 20 months. The most frequent level of discopathy was L4-L5 with 62 patients (59.6%) followed by L5-S1 level with 52 patients (50%). Eighty-three patients suffered from low back pain, 21 of which were associated with radiculopathy. The status of 82 patients improved after surgery according to the Oswestry Disability Index score, and 92 patients returned to work. Conclusions The results indicate that TDA is a good alternative treatment for lumbar spine disk disease, particularly for patients with disabling and chronic low back pain. This technique contributes to improve living conditions with correct patient selection for surgery. PMID:25705336

    Full Text Available Purpose. The relatively new and less-invasive therapeutic alternative “interspinous process decompression device (IPD” is expected to result in improved symptoms of neurogenic intermittent claudication (NIC caused by lumbar spinal stenosis. The aim of the study was to analyze IPD position particularly regarding damage originating from surgical implantation. Methods. Anatomic assessments were performed on a fresh human cadaver. For the anatomic examination, the lumbar spine was plastinated after implantation of the IPDs. After radiographic control, serial 4 mm thick sections of the block plastinate were cut in the sagittal (L1–L3 and horizontal (L3–L5 planes. The macroanatomical positioning of the implants was then analyzed. The insertion procedure caused only little injury to osteoligamentous or muscular structures. The supraspinous ligament was completely intact, and the interspinous ligaments were not torn as was initially presupposed. No osseous changes at the spinal processes were apparent. Contact of the IPD with the spinous processes was visible, so that sufficient biomechanical limitation of the spinal extension seems likely. Conclusions. Minimally invasive IPD implantation with accurate positioning in the anterior portion of the interspinous place is possible without severe surgical trauma.

    Our aim was to study the safety and outcomes of posterior instrumentation and transforaminal lumbar interbody fusion (TLIF) for treating pyogenic lumbar spondylodiscitis. Retrospective analysis was performed on prospectively collected data of 27 consecutive cases of lumbar pyogenic spondylodiscitis treated with posterior instrumentation and TLIF between January 2009 and December 2012. Cases were analysed for safety, radiological and clinical outcomes of transforaminal interbody fusion using bone graft ± titanium cages. Interbody metallic cages with bone graft were used in 17 cases and ten cases used only bone graft. Indications for surgical treatment were failed conservative management in 17, neurodeficit in six and significant bony destruction in four. There were no cases reporting cage migration, loosening, pseudoarthrosis or recurrence of infection at a mean follow-up of 30 months. Clinical outcomes were assessed using Kirkaldy-Willis criteria, which showed 14 excellent, nine good, three fair and one poor result. Mean focal deformity improved with the use of bone graft ± interbody cages, and the deformity correction was maintained at final follow-up. Mean pre-operative focal lordosis for the graft group was 8.5° (2-16.5°), which improved to 10.9 °(3.3-16°); mean pre-operative focal lordosis in the group treated with cages was 6.7 °(0-15°), which improved to 7°(0-15°) . TLIFs with cages in patients with pyogenic lumbar spondylodiscitis allows for acceptable clearance of infection, satisfactory deformity correction with low incidence of cage migration, loosening and infection recurrence.

    A randomized, controlled, prospective multicenter trial comparing the outcomes of neurogenic intermittent claudication (NIC) patients treated with the interspinous process decompression system (X STOP) with patients treated nonoperatively. To determine the safety and efficacy of the X STOP interspinous implant. Patients suffering from NIC secondary to lumbar spinal stenosis have been limited to a choice between nonoperative therapies and decompressive surgical procedures, with or without fusion. The X STOP was developed to provide an alternative therapeutic treatment. METHODS.: 191 patients were treated, 100 in the X STOP group and 91 in the control group. The primary outcomes measure was the Zurich Claudication Questionnaire, a patient-completed, validated instrument for NIC. At every follow-up visit, X STOP patients had significantly better outcomes in each domain of the Zurich Claudication Questionnaire. At 2 years, the X STOP patients improved by 45.4% over the mean baseline Symptom Severity score compared with 7.4% in the control group; the mean improvement in the Physical Function domain was 44.3% in the X STOP group and -0.4% in the control group. In the X STOP group, 73.1% patients were satisfied with their treatment compared with 35.9% of control patients. The X STOP provides a conservative yet effective treatment for patients suffering from lumbar spinal stenosis. In the continuum of treatment options, the X STOP offers an attractive alternative to both conservative care and decompressive surgery.

    To assess the clinical efficacy of mini-invasive transforaminal lumbar interbody fusion (TLIF) through the Wiltse approach for treating lumbar spondylolytic spondylolisthesis. In this retrospective controlled study, 69 cases with lumbar spondylolytic spondylolisthesis treated in Qilu hospital from April to November 2014 were randomly assigned to Wiltse approach (31 cases, 16 male, 15 female; mean age 45.1 years) and traditional approach groups (38 cases, 21 male, 17 female; 47.2 years. In the Wiltse approach group, the affected level was L4, 5 in 19 cases and L5 S1 in 12, 9 of whom had low back pain (LBP) only and 21 both LBP and leg pain. There were 17 cases of I degree and 14 of II degree spondylolisthesis. Pre-operative Japanese Orthopedic Association (JOA) score was 13.1 ± 2.6; visual analog scale (VAS) for LBP 7.4 ± 1.2; VAS for leg pain 6.1 ± 2.0 and Oswestry disability index (ODI) score 42.2% ± 1.2%. In the traditional approach group, the affected level was L4, 5 in 22 cases and L5 S1 in 16, 11 of whom had LBP only and 27 both LBP and leg pain. There were 21 cases of I degree and 17 of II degree spondylolisthesis. Pre-operative JOA score was 12.8 ± 1.2; VAS for LBP 6.9 ± 1.1; VAS for leg pain 7.1 ± 2.0 and ODI score 41.2% ± 2.0%. The JOA score, VAS for LBP and leg pain, ODI dynamic X-rays, CT and/or MR were evaluated 3 and 6 months and 1 year postoperatively. There were no differences in sex, age, affected levels, spondylolisthesis degree, pre-operative JOA score, VAS for LBP or leg pain and ODI score between the two groups (P > 0.05). The incision length, blood loss and time to achieving exposure were better in the Wiltse approach than the traditional approach group (P 0.05). The interbody fusion rate was not significantly different between the groups (P > 0.05). There were no complications of internal fixation in either group. TLIF via both approaches has satisfactory clinical efficacy. TLIF through the Wiltse approach significantly reduces the

    Polymyalgia rheumatica (PMR) is a common inflammatory disease in older people characterized by shoulder and/or pelvic girdle, and cervical and, occasionally, lumbar pain. Interspinous bursitis has been suggested as a potential cause of spinal symptoms. We evaluated, by 18 F-fluorodeoxyglucose (FDG) positron emission tomography integrated with computed tomography (PET/CT), the vertebral structures involved in PMR in a cohort of consecutive, untreated patients. Sixty-five consecutive patients with PMR were studied. After a standardized physical examination, which included evaluation of pain and tenderness in the vertebral column, they underwent FDG-PET/CT. Sites of increased uptake and their correlation with spontaneous and provoked pain were recorded. For comparison, FDG-PET/CT was performed also in 65 age- and sex-matched controls and in 10 rheumatoid arthritis (RA) patients. The most frequent site of spontaneous and provoked pain was the cervical portion. FDG uptake was more frequent in the lumbar portion than at any other location, and in the cervical rather than in the thoracic portion (P bursitis (r = 0.34, P = 0.007). None of the control patients and one out of ten RA patients showed interspinous bursitis. Interspinous bursitis is a frequent finding in the lumbar spine of patients with PMR. However, it is not associated with clinical symptoms and can hardly explain the spinal pain reported by the patients. Cervical pain is more frequent than lumbar pain in PMR patients and may be caused by shoulder girdle involvement.

    OBJECTIVE Pedicle screw-rod-based hybrid stabilization (PH) and interspinous device-based hybrid stabilization (IH) have been proposed to prevent adjacent-segment degeneration (ASD) and their effectiveness has been reported. However, a comparative study based on sound biomechanical proof has not yet been reported. The aim of this study was to compare the biomechanical effects of IH and PH on the transition and adjacent segments. METHODS A validated finite element model of the normal lumbosacral spine was used. Based on the normal model, a rigid fusion model was immobilized at the L4-5 level by a rigid fixator. The DIAM or NFlex model was added on the L3-4 segment of the fusion model to construct the IH and PH models, respectively. The developed models simulated 4 different loading directions using the hybrid loading protocol. RESULTS Compared with the intact case, fusion on L4-5 produced 18.8%, 9.3%, 11.7%, and 13.7% increments in motion at L3-4 under flexion, extension, lateral bending, and axial rotation, respectively. Additional instrumentation at L3-4 (transition segment) in hybrid models reduced motion changes at this level. The IH model showed 8.4%, -33.9%, 6.9%, and 2.0% change in motion at the segment, whereas the PH model showed -30.4%, -26.7%, -23.0%, and 12.9%. At L2-3 (adjacent segment), the PH model showed 14.3%, 3.4%, 15.0%, and 0.8% of motion increment compared with the motion in the IH model. Both hybrid models showed decreased intradiscal pressure (IDP) at the transition segment compared with the fusion model, but the pressure at L2-3 (adjacent segment) increased in all loading directions except under extension. CONCLUSIONS Both IH and PH models limited excessive motion and IDP at the transition segment compared with the fusion model. At the segment adjacent to the transition level, PH induced higher stress than IH model. Such differences may eventually influence the likelihood of ASD.

    Many treatment techniques have been used for refractory lumbar facet joint pain; however, their efficacy has been controversial. In this study, we investigated the clinical efficacy and safety of intra-articular pulsed radiofrequency for the treatment of refractory lumbar facet joint pain in patients with low back pain. Twenty patients with refractory lumbar facet joint pain were recruited, and each patient was treated via intra-articular pulsed radiofrequency. The treatment effects were measured with a numerical rating scale, and the technical accuracy of intra-articular pulsed radiofrequency treatment was evaluated independently by 2 radiologists. Any adverse events or complications also were checked. We performed intra-articular pulsed radiofrequency treatment at 48 levels of the lumbar facet joints in 20 patients (5 men and 15 women; mean age, 64.50 ± 10.65 years) with refractory lumbar facet joint pain. Pain scores were significantly reduced at 1 month, 3 months, and 6 months after treatment (P radiofrequency results in all 20 patients, without any serious adverse effects. Treatment using intra-articular pulsed radiofrequency is an alternative to other techniques in patients with refractory lumbar facet joint pain. Copyright © 2018 Elsevier Inc. All rights reserved.

    A combined in vitro and finite-element analysis was completed to assess the biomechanical effect of a new interspinous implant on the lumbar spine. The aim was to investigate the effect of an interspinous implant on the biomechanical behavior of a vertebral segment. An in vitro study on L3-L5 segments from fresh human cadavers was conducted combined with a 3-dimensional finite-element analysis. Intact, injured, and instrumented states of L4-L5 were compared loaded in flexion-extension, lateral-bending, and torsion. The evaluated implant is an interspinous spacer fixed to the spine by 2 polyester braids looped around the proximal and distal spinous. The effect of the implant appeared mainly in flexion-extension: experimental results showed reduced range of motion of the instrumented spine regarding the injured and intact one; and finite-element analysis indicated a decrease of disc stresses and increase of loads transmitted to the spinous processes. In this in vitro and finite-element analysis, the role of the new interspinous implant appeared to reduce motion without suppressing it and to lower stress in the disc fibers and anulus matrix. Further in vivo investigations are necessary to draw definitive conclusions.

    To observe the clinical effect of post-extension pulling massage in treating lumbar disc herniation. From January 2008 to December 2008, 61 patients with lumbar disc herniation, 34 males and 27 females, ranging in age from 17 to 67 years with an average of 42.6 years, were treated with post-extension pulling massage after continued traction for 30 minutes (on alternate days one time, 3 times as a course of treatment). There was bulging type in 9 cases, hernia type in 22, free type in 30. After a course of treatment, the clinical effects were evaluated according to standard of Macnab, the items included pain, lumbar activity, normal work and life of patients. All patients were followed up from 1 to 9 months with an average of 4.6 months. After treatment, the symptoms and signs of patients had obviously improved in above aspects. According to standard of Macnab, 48 cases got excellent result, 10 good, 2 fair, 1 poor. The post-extension pulling massage in treating lumbar disc herniation can obtain satisfactory results, which have localized site of action, small compression for vertebral body and can reduce accidental injury.

    The role of interspinous devices (ISD) after lumbar herniated disc surgery for the prevention of postoperative back pain is controversial. The aim of this comparative prospective study was to determine outcomes in a selective cohort with L5-S1 disc herniation and degenerative disc changes after microdiscectomy with or without insertion of an ISD. One hundred and two consecutive patients underwent an L5-S1 microdiscectomy with or without implantation of an ISD. Group 1 consisted of 47 patients, with mild (n=22), moderate (n=14) or severe (n=11) degenerative disc changes who had microdiscectomy alone. Group 2 comprised 45 patients with similar types of disc changes who underwent microdiscectomy with an ISD implant. The Visual Analogue Scale (VAS) was used to grade low-back pain and postoperative clinical status was rated according to the modified MacNab criteria. Mean VAS score for low-back pain improved significantly at 1 year follow-up from 7.3 at baseline to 2.75 (pdisc changes were more likely to achieve improvement of their low-back pain when treated with both microdiscectomy and ISD insertion.

    Rigid and semi-rigid fixations are investigated several times in order to compare their biomechanical stability. Interbody fusion techniques are also preferable for maintaining the sagittal balance by protecting the disk height. In this study, the biomechanical comparison of semi-rigid and rigid fixations with posterior lumbar interbody fusion or transforaminal lumbar interbody fusion procedures is conducted under trauma. There were four different test groups to analyze the effect of acute load on treated ovine vertebrae. First and second groups were fixed with polyetheretherketone rods and transforaminal lumbar interbody fusion and posterior lumbar interbody fusion cages, respectively. Third and fourth groups were fixed with titanium rods and posterior lumbar interbody fusion and transforaminal lumbar interbody fusion cages, respectively. The drop tests were conducted with 7 kg weight. There were six samples in each group so the drop test repeated 24 times in total. The test samples were photographed and X-rayed (laterally and anteroposteriorly) before and after drop test. Two fractures were observed on group 1. Conversely, there were no fractures observed for group 2. There were no anterior element fractures for both groups 1 and 2. However, one fracture seen on group 3 was anterior element fracture, whereas the other three were posterior element fractures. All three fractures were anterior element fractures for group 4. Treated vertebrae with polyetheretherketone rods and posterior lumbar interbody fusion cages showed the best durability to the drop tests among the groups. Semi-rigid fixation gave better results than rigid fixation according to failed segments. Posterior lumbar interbody fusion cages seem to be better option for semi-rigid fixation, however mentioned surgical disadvantages must be considered.

    OBJECTIVE The aim of this study was to evaluate predictive factors for outcome after lumbar disc herniation surgery in young patients. METHODS In the national Swedish spine register, the authors identified 180 patients age 20 years or younger, in whom preoperative and 1-year postoperative data were available. The cohort was treated with primary open surgery due to lumbar disc herniation between 2000 and 2010. Before and 1 year after surgery, the patients graded their back and leg pain on a visual analog scale, quality of life by the 36-Item Short-Form Health Survey and EuroQol-5 Dimensions, and disability by the Oswestry Disability Index. Subjective satisfaction rate was registered on a Likert scale (satisfied, undecided, or dissatisfied). The authors evaluated if age, sex, preoperative level of leg and back pain, duration of leg pain, pain distribution, quality of life, mental status, and/or disability were associated with the outcome. The primary end point variable was the grade of patient satisfaction. RESULTS Lumbar disc herniation surgery in young patients normalizes quality of life according to the 36-Item Short-Form Health Survey, and only 4.5% of the patients were unsatisfied with the surgical outcome. Predictive factors for inferior postoperative patient-reported outcome measures (PROM) scores were severe preoperative leg or back pain, low preoperative mental health, and pronounced preoperative disability, but only low preoperative mental health was associated with inferiority in the subjective grade of satisfaction. No associations were found between preoperative duration of leg pain, distribution of pain, or health-related quality of life and the postoperative PROM scores or the subjective grade of satisfaction. CONCLUSIONS Lumbar disc herniation surgery in young patients generally yields a satisfactory outcome. Severe preoperative pain, low mental health, and severe disability increase the risk of reaching low postoperative PROM scores, but are only of

    Prospective database study. To grasp the characteristics of surgically treated cases with lumbar spondylolysis or isthmic spondylolisthesis. A detailed analysis of surgically treated cases with spondylolysis or isthmic spondylolisthesis has never been reported. An epidemiological study in Japan conducted on 2000 subjects found the incidence of lumbar spondylolysis in the Japanese general population (population-based study) to be 5.9% (males: 7.9%, females: 3.9%). Among 124 vertebrae with spondylolysis, there were 0.8% L2 lesions, 3.2% L3 lesions, 5.6% L4 lesions, and 90.3% L5 lesions, including 5 cases (4.3%) with multiple-level lesions. We have been registering surgically treated spine cases in our database since 2000. From this database, we prospectively collected cases with lumbar spondylolysis or isthmic spondylolisthesis that were treated surgically between January 2000 and December 2009. We determined the age at surgery, sex, and vertebral level of spondylolysis. Of the 564 spondylolysis patients treated surgically, 66.8% were male and 33.2% were female. The mean age at surgery was 52.5 years (range, 13-84 y). There were 585 vertebrae with spondylolysis including 21 cases (3.7%) with multiple-level lesions. L5 spondylolysis affected 432 vertebrae and was the most common location (73.8%), followed by 125 L4 lesions (21.4%), 24 L3 lesions (4.1%), and 2 L2 lesions (0.7%). The percentage of L4 lesions in our study was significantly higher and of L5 lesions was significantly lower than those lesions' percentages in the population-based study. L4 spondylolysis may be more unstable or cause clinical symptoms more frequently leading to more surgical intervention. The percentage of multiple-level spondylolysis was similar between the 2 studies, suggesting these patients respond relatively well to conservative treatment. The male/female ratio was 2:1 in both studies, indicating that males and females require surgery at a similar frequency.

    Full Text Available Objective To analyze the causes of surgical complications after treatment of lumbar disc herniation (LDH and lumbar intervertebral foraminal stenosis by percutaneous transforaminal endoscopic discectomy (PTED.  Methods From December 2009 to December 2014, 286 patients with LDH (N = 201 and lumbar intervertebral foraminal stenosis (N = 85 were confirmed by X-ray, CT or MRI and treated by PTED in our hospital. Visual Analogue Scale (VAS was used to evaluate the degree of pain in each paitent before and after operation. The curative effect was evaluated by Macnab score. Surgical complications were recorded to find out the causes and methods to prevent them.  Results All cases were followed up for 3 months, and the VAS score decreased significantly compared with preoperation [1.00 (0.00, 1.05 vs 8.50 (7.75, 9.25; Z = 2.825, P = 0.050]. According to Macnab score, the rate of excellent and good functional recovery was 95.45% (273/286. Procedure-related complications included nerve injury in 8 cases (2.80%, hemorrhage at the operation site and hematoma formation around nerve root in 6 cases (2.10%, rupture of dural sac in one case (0.35%, muscle cramps in 3 cases (1.05%, surgical infection in one case (0.35%, postoperative recurrence in 4 cases (1.40%. All patients with complications were cured after symptomatic treatment. Conclusions The overall effect of percutaneous transforaminal endoscopic discectomy for treating lumbar disc herniation and lumbar intervertebral foraminal stenosis is satisfactory, which has a low incidence rate of postoperative complications. Some tips can effectively reduce the rate of surgical complications such as preoperative evaluation, precise performance, careful hemostasis, shortening the operation time and postoperatively symptomatic treatment, etc. DOI: 10.3969/j.issn.1672-6731.2016.04.007

    Objective: To compare outcomes after imaging-guided transforaminal lumbar nerve root blocks in MRI confirmed symptomatic disc herniation patients with and without Modic changes (MC). Methods: Consecutive adult patients with MRI confirmed symptomatic lumbar disc herniations and an imaging-guided lumbar nerve root block injection who returned an outcomes questionnaire are included. Numerical rating scale (NRS) pain data was collected prior to injection and 20–30 min after injection. NRS and overall improvement were assessed using the patient's global impression of change (PGIC) scale at 1 day, 1 week and 1 month post injection. The proportion of patients with and without MC on MRI as well as Modic I and Modic II was calculated. These groups were compared for clinically relevant ‘improvement’ using the Chi-squared test. Baseline and follow-up NRS scores were compared for the groups using the unpaired t-test. Results: 346 patients are included with MC present in 57%. A higher percentage of patients without MC reported ‘improvement’ and a higher percentage of patients with MC reported ‘worsening’ but this did not reach statistical significance. The numerical scores on the PGIC and NRS scales showed that patients with MC had significantly higher pain and worse overall improvement scores at 1 month (p = 0.048 and p = 0.03) and a significantly lower 1 month NRS change score (p = 0.04). Conclusions: Patients with MRI confirmed symptomatic lumbar disc herniations and MC report significantly lower levels of pain reduction after a lumbar nerve root block compared to patients without MC.

    The pattern of distribution of surgically treated symptomatic prolapsed lumbar and sacral intervertebral discs has been published, though scantily, especially in males. We decided to look at our own series, compare and contrast ours with some of those published. We treated 88 locations of this lesion in 68 males. The clinical features were those of lower back pains, with or without radiation into the lower extremities, sensory loss and paresis of the limbs. There was a case of loss of urinary bladder and ano-rectal control. All lesions were confirmed through cauda-equinograms and treated under general anaesthesia in knee-chest position (MECCA position). The patients were followed up for 3-6 months post-operatively. There were 88 locations in 68 males of 21-70 years of age, with 29 prolapses occurring during the age range 31-40 years, while 54 locations were on the left and 48 at L4/5. The procedures were well tolerated by all patients and there were no post-operative complications. This lesion in our series occurred mostly on the left, at the L4/5 level and peaked at 31-40 years age range. The predictability of occurrence of this disease, using side, level and age is still not feasible in males from our series.

    A 40-year-old man presented with a severe headache, lower back pain, and lower abdominal pain 1 month after a head injury caused by falling. Computed tomography (CT) of the head demonstrated bilateral chronic subdural hematoma (CSDH) with a significant amount in the left frontoparietal region. At the same time, magnetic resonance imaging (MRI) of the lumbar spine also revealed CSDH from L2 to S1 level. A simple drainage for the intracranial CSDH on the left side was performed. Postoperatively, the headache was improved; however, the lower back and abdominal pain persisted. Aspiration of the liquefied spinal subdural hematoma was performed by a lumbar puncture under fluoroscopic guidance. The clinical symptoms were dramatically improved postoperatively. Concomitant intracranial and spinal CSDH is considerably rare so only 23 cases including the present case have been reported in the literature so far. The etiology and therapeutic strategy were discussed with a review of the literature. Therapeutic strategy is not established for these two concomitant lesions. Conservative follow-up was chosen for 14 cases, resulting in a favorable clinical outcome. Although surgical evacuation of lumbosacral CSDH was performed in seven cases, an alteration of cerebrospinal fluid (CSF) pressure following spinal surgery should be reminded because of the intracranial lesion. Since CSDH is well liquefied in both intracranial and spinal lesion, a less invasive approach is recommended not only for an intracranial lesion but also for spinal lesion. Fluoroscopic-guided lumbar puncture for lumbosacral CSDH following burr hole surgery for intracranial CSDH could be a recommended strategy.

    Abstract The aim of this study is to report our 39 patients treated with anterior debridement and autologous iliac bone grafting with or without anterior instrumentation, which is the presumed treatment of choice for thoracic or lumbar spondylodiscitis. Our patients underwent surgical treatment of spondylodiscitis using anterior debridement and autologous iliac bone grafting with or without anterior instrumentation and were analyzed with a mean follow-up of 8 years (range, 2–11 years). Kaneda 2-rod system instrumentation was used in 12 patients, in total. Clinical outcomes were assessed by the Frankel grade. Radiographic fusion was characterized based on 3-dimensional computed tomography. Of the whole group, 20 patients suffered from tuberculous spondylodiscitis and 19 suffered from hematogenous spondylodiscitis. Pathogens responsible for pyogenic infection included Staphylococcus aureus (4 patients), Pseudomonas aeruginosa (3 patients), and Brucella melitensis (1 patient). Fifteen patients had thoracic involvement, 20 had lumbar involvement, and 4 had thoracolumbar junction involvement. Preoperative neurological deficits were noted in 13 of the 39 patients. In terms of Frankel grade, 8 patients have improved, 4 have remained the same, and 1 patient has worsened during the follow-up period. Imaging-documented fusion was achieved in 23 of 27 patients in the graft group (85% fusion rate) and 11 of 12 patients in the graft + Kaneda instrumentation group (91% fusion rate). There was no instrumentation failure, loosening, or graft-related complication such as slippage or fracture of the graft. This approach demonstrated a good recovery rate of neurological functions and a high fusion rate. PMID:26632729

    Abstract Transpedicular screw (TPS) fixation in unstable thoracic and lumbar (TL) spine fractures remains technically difficult because of destroyed anatomical landmarks, unstable gross segments, and discrepancies in anatomic orientation using conventional anatomic landmarks, fluoroscopic guidance, or computed tomography (CT)-based navigation. In this study, we evaluated the safety and accuracy of TPS placement under intraoperative computed tomography (iCT) navigation in managing unstable TL spine fractures. From 2010 to 2013, we retrospectively reviewed the Spine Operation Registry records of patients who underwent posterior instrumented fusion to treat unstable TL spine fractures via the iCT navigation system. An unstable spine fracture was identified as AO/Magerl classification type B or type C. In all, 316 screws in 37 patients with unstable TL spine fractures were evaluated and involved 7 thoracic, 23 thoracolumbar junctional, and 7 lumbar fractures. The accuracy of TPS positioning in the pedicle without breach was 98% (310/316). The average number of iCT scans per patient was 2.1 (range 2–3). The average total radiation dose to patients was 15.8 mSv; the dose per single level exposure was 2.7 mSv. The TPS intraoperative revision rate was 0.6% (2/316) and no neurovascular sequela was observed. TPS fixation using the iCT navigation system obtained a 98% accuracy in stabilizing unstable TL spine fractures. A malplaced TPS could be revised during real-time confirmation of the TPS position, and no secondary operation was required to revise malplaced screws. The iCT navigation system provides accurate and safe management of unstable TL spine fractures. In addition, operating room personnel, including surgeons and nurses, did not need to wear heavy lead aprons as they were not exposed to radiation. PMID:25997042

    Imaging investigations (radiculography, X-ray, CT, MRI) constitute an integral part of the therapeutic process in the treatment of patients suffering from lumbar discopathy. The results obtained with the imaging techniques provide the crucial data concerning the stage of disease development; assist the choice of optimal therapy method and the evaluation of the therapeutic actions efficiency. The aim of the study was to analyze the results of CT and MRI investigations carried out on patients suffering from lumbar discopathy, who had been treated with conservative or surgical methods. 665 patients aged between 16 and 76 years with discopathy at L4-L5, L5-S1 levels were enrolled to the study. In the analyzed group, 348 patients received only conservative therapy whereas 317 patients underwent surgical procedures. CT and MRI investigations were applied at the beginning of the observation (W), after three years (III) and after ten years (X) since the operation (or exclusively conservative treatment). The results obtained with imaging techniques were divided into three categories: intradiscal, peridiscal and disc-related changes caused by herniation of vertebral discs. During the subsequent periods of inspection, the rising number of degenerative changes was found. The progression of the imaging technique results concerned both the L4-L5, L5-S1 spaces, which showed distortion initially, and the L3-L4, L2-L3 levels, which were not degenerated in the preliminary examination. The remote examination showed that the number of degenerations in the two examined groups was substantially higher than it had been during the preliminary examination. The total number of degenerative changes among the patients operated on was higher than among the patients in conservative treatment. The number of degenerative changes of the spine grows from level L2-L3 to level L5-S1. The stage of spinal degenerative changes rises along with the duration of the disease. The patients operated on show

    Weight training can have a very positive impact on the body by improving both the functioning of internal organs and motor coordination. Weakening of the muscles leads to spinal pain, which in turn reduces one's mobility, this further decreasing muscular strength. Weight training can be used to treat both motor dysfunction and lumbar pain, but it is crucial to combine it with flexibility exercises. The aim of the presented study is to demonstrate the need for including physical exercises into the rehabilitation of patients diagnosed with degenerative disc disease in the lumbar vertebrae. The research was carried out on 120 patients who were agricultural workers. Each of them had been diagnosed as qualifying for surgery due to a herniated nucleus pulposus at the L4/L5 and L5/S1 levels. After all conventional methods had been tried, strength exercises were applied. The equipment used for the exercises included a multi- gym, dumbbells, weight training rods with plates chosen for a particular groups of muscles. General fitness exercises were also a part of the programme. The observed results indicate that, sooner or later, weight training leads to full recovery and as such is therapeutically indispensable. By developing antagonistic and synergistic muscular actions, exercises bring relief and allow reduction in the intake of analgesic drugs. As a result, all the patients recuperated. It should be remembered that one week's immobilization reduces muscle strength and endurance by 20%. All the patients who enrolled in the weight training programme were able to avoid back surgery. Systematic exercises improved their neuro-muscular coordination.

    Full Text Available We report a case of intractable chronic low-back pain in a gymnast that was caused by ligamentopathia in the interspinous region of the lumbar vertebrae. Sprained interspinous ligaments are a common mechanical cause of acute low-back pain in athletes. Although conservative therapy is generally effective in such cases, in this case it was not. The patient experienced severe low-back pain during lumbar flexion with tension between the L5/S interspinous ligaments. We performed interspinous fixation by using a spinous process plate system, which has been developed for short in situ fusions, and following which the low-back pain resolved. Conservative therapy for low-back pain caused by ligamentopathia is first-line choice, but interspinous fixation with instrumentation might be recommended in intractable cases with conservative therapy.

    Abstract Background: The application of tubular microscopes discectomy (TMD) was supposed to have similar or better results than conventional microdiscectomy (CMD). However, this conclusion had not been verified by sufficient evidence. Therefore, the focus of this meta-analysis was to assess the efficiency, safety, and clinical outcome of these 2 surgical procedures for treating lumbar disk herniation (LDH). Methods: PubMed, Embase, and Cochrane Collaboration Central databases were searched for studies which compared the results of TMD and CMD for the treatment of LDH up to July 2017. Data analysis was conducted using RevMan 5.3. A standardized electronic form of 17 predefined criteria from the Consort statement was used for the quality assessment. Results: Eight randomized controlled trials (RCT) and 2 retrospective studies were included in this review, including 804 patients. The pooled analysis showed that there was no significant difference in operative time (P = .38), blood loss (P = .14), the length of hospital stay (P = .47), the rate of intraoperative complications (P = .79), postoperative complications (P = .16), dural tear (P = .87), the reoperation (P = .20), the short-term back visual analog scale (VAS) scores (P = .76), the long-term back VAS scores (P = .64), the short-term leg VAS scores (P = .09), the long-term leg VAS scores (P = .35), and the Oswestry disability index (ODI) scores (P = .41). Conclusion: The results of this meta-analysis demonstrate that TMD and CMD are both safe and effective surgical procedures which can be recommended for treating LDH. Additionally, the conclusion should be cautiously treated, because it was reached in the context of limited amount of studies and relatively small sample size. Therefore, future studies with good design and more large samples are required to validate this conclusion. PMID:29384882

    Herniated lumbar intervertebral disc (HLID) is a pathological condition frequently seen in rehabilitation medicine that is characterized by the compression of one or more nerve roots. The aim of this study was to describe the effects of Global Postural Reeducation on function and pain in patients with herniated disc at levels L4-L5 and/or L5-S1. Twenty-four consecutive subjects were treated with Global Postural Reeducation. Before treatment, patients reported median average pain duration of 180 days. At the beginning of treatment and on days 15, 45, 120, and 180, all completed the Quebec Back Pain Disability Scale and the Numeric Pain Rating Scale. The median value of the Quebec Back Pain Disability Scale score decreased from 49 points at baseline to 22 points at 45 days. Moreover, the median Numeric Pain Rating Scale score decreased from 6 points at baseline to 2 points at 45 days. The present study indicates that Global Postural Reeducation is suitable for the conservative management of HLID. Moreover, patients gained a therapeutic benefit from being active participants in their recovery.

    Conclusion: Literature review of adults TCS associated with lumbar spinal degenerative disease as lumbar canal stenosis or disc herniation, is reported. Moderate entity of traction of spinal cord may remain asymptomatic in childhood and may result in delayed neurological deficits in adult life. The stretching of conus medullaris and spinal nerves of cauda equina, reduces regional blood flow and causes neural death and fibrous tissue replacement. Sudden or progressive onset of paraparesis with spastic gait, bladder dysfunction and acute low back pain in patient with history of spinal dysraphism must be considered as possible lumbar spinal cord compression caused by low lying cord related to TCS. Surgical decompression should be performed as early as possible to ensure neurological recovery. XLIF approach seems to be safe and fast and represent an excellent surgical option to obtain spinal cord indirect decompression and lumbar interbody fusion.

    Lumbar spondylosis is a chronic, noninflammatory disease caused by degeneration of lumbar disc and/or facet joints. The etiology of lumbar spondylosis is multifactorial. Patients with lumbar spondylosis complain of a broad variety of symptoms including discomfort in the low back lesion, whereas some of them have radiating leg pain or neurologenic intermittent claudication (lumbar spinal stenosis). The majority of patients with spondylosis and stenosis of the lumbosacral spine can be treated nonsurgically. Nonsteroidal anti-inflammatory drugs and COX-2 inhibitors are helpful in controlling symptoms. Prostaglandin, epidural injection, and transforaminal injection are also helpful for leg pain and intermittent claudication. Operative therapy for spinal stenosis or spondylolisthesis is reserved for patients who are totally incapacitated by their condition.

    To observe the clinical efficacy differences between modified lateral position and prone position in patients treated with electroacupuncture (EA) for lumbar herniated disc (LHD). Seventy-six patients with LHD were randomly divided into a lateral position group and a prone position group, 38 cases in each one. The acupoint selection and treatment method were identical in the two groups except the position. Mingmen (GV 4), Yaoyangguan (GV 3), Dachangshu (BL 25), Xiaochangshu (BL 27), Zhibian (BL 54) and Huantiao (GB 30) were selected. EA was given three times a week, ten times were taken as one course and totally 20 times were given. The visual analogue scale (VAS) and Japanese orthopaedic association (JOA) scale were taken as efficacy criteria, which were evaluated before and after treatment as well as one month after treatment. After treatment, VAS and JOA were significantly improved in the two groups (lateral position group:JOA 10.60±2.60 vs 18.92±3.87, VAS 8.13±0.99 vs 2.34±0.81; prone position group:JOA 10.94±2.06 vs 17.02±3.96, VAS 8.02±1.05 vs 2.86±0.96, all P <0.01); the VAS and JOA in the lateral position group were higher than those in the prone position group (both P <0.05). One month after treatment, VAS and JOA were significantly improved in the two groups (all P <0.01), which was more significant in the lateral position group (both P <0.05). The treatment position could influence the efficacy of EA for LHD, and lateral position pre-sents certain advantages to prone position group.

    To explore the effects differences for the third lumbar transverse process syndrome between acupuncture mainly at zygapophyseal joint and transverse process and conventional acupuncture. Eighty cases were randomly assigned into an observation group and a control group, 40 cases in each one. In the observation group, patients were treated with acupuncture at zygapophyseal joint, transverse process, the superior gluteus nerve into the hip point and Weizhong (BL 40), and those in the control group were treated with acupuncture at Qihaishu (BL 24), Jiaji (EX-B 2) of L 2 -L 4 , the superior gluteus nerve into the hip point and Weizhong (BL 40). The treatment was given 6 times a week for 2 weeks, once a day. The visual analogue scale (VAS), Japanese Orthopaedic Association (JOA) low back pain score and simplified Chinese Oswestry disability index (SC-ODI) were observed before and after treatment as well as 6 months after treatment, and the clinical effects were evaluated. The total effective rate in the observation group was 95.0% (38/40), which was significantly higher than 82.5% (33/40) in the control group ( P process for the third lumbar transverse process syndrome achieves good effect, which is better than that of conventional acupuncture on relieving pain, improving lumbar function and life quality.

    When a cervical or thoracic benign intradural spinal tumor (BIST) coexists with lumbar degenerative diseases (LDD), diagnosis can be difficult. Symptoms of BIST-myelopathy can be mistaken as being related to LDD. Worse, an unnecessary lumbar surgery could be performed. This study was conducted to analyze cases in which an erroneous lumbar surgery was undertaken in the wake of failure to identify BIST-associated myelopathy. Cases were found in a hospital database. Patients who underwent surgery for LDD first and then another surgery for BIST removal within a short interval were studied. Issues investigated included why the BISTs were missed, how they were found later, and how the patients reacted to the unnecessary lumbar procedures. Over 10 years, 167 patients received both surgeries for LDD and a cervical or thoracic BIST. In 7 patients, lumbar surgery preceded tumor removal by a short interval. Mistakes shared by the physicians included failure to detect myelopathy and a BIST, and a hasty decision for lumbar surgery, which soon turned out to be futile. Although the BISTs were subsequently found and removed, 5 patients believed that the lumbar surgery was unnecessary, with 4 patients expressing regrets and 1 patient threatening to take legal action against the initial surgeon. Concomitant symptomatic LDD and BIST-associated myelopathy pose a diagnostic challenge. Spine specialists should refrain from reflexively linking leg symptoms and impaired ability to walk to LDD. Comprehensive patient evaluation is fundamental to avoid misdiagnosis and wrong lumbar surgery. Copyright © 2017 Elsevier Inc. All rights reserved.

    Radicular lumbar back pain is an important public health problem not yet benefiting from a unequivocal treatment approach. Medical and physical therapies represent the first solution; however, when these fail, the second therapeutic step is still controversial and mini-invasive treatments may play an important role. In these cases oxygen-ozone therapy has been proved to be a very safe and effective option that is widely used with different modalities. This paper, by reviewing oxygen-ozone therapy literature data, aims to describe the rationale of oxygen-ozone therapy for the treatment of lumbar disk herniations, propose an effective procedural technique and clarify patient selection criteria; furthermore, complications and follow-up management are also considered. © The Author(s) 2016.

    Case report. We present a case of lumbar Charcot arthropathy successfully treated surgically using posterior 3-column resection, spinal shortening, and fusion. The operative treatment of Charcot arthropathy of the spine has conventionally been a combination of anterior and posterior surgery. The morbidity associated with these surgical procedures can be considerable. A posterior-only approach to the problem would avoid the additional morbidity associated with an anterior approach. We present a case of lumbar Charcot arthropathy with deformity treated successfully using such a procedure. Discussion of the patient's clinical and radiologic history, the technical merits of the operative intervention and a review of the relevant background literature are presented. A multilevel, single-stage, posterior 3-column resection with primary shortening and instrumented fusion augmented with rhBMP2 in a multiply operated patient with deformity provided a optimal biologic and mechanical environment for healing of the Charcot arthropathy and improved the sagittal and coronal profile of the spine. A single-stage, multilevel, posterior 3-column resection and primary shortening can be a useful surgical strategy in symptomatic patients with Charcot arthropathy of the spine.

    We assessed the long-term outcomes of patients with lumbar disc herniation treated with percutaneous lumbar discectomy (PLD) or microendoscopic discectomy (MED). A retrospective study was performed in consecutive patients with lumbar disc herniation treated with PLD (n = 129) or MED (n = 101) in a single hospital from January 2000 to March 2002. All patients were followed up with MacNab criteria and self-evaluation questionnaires comprising the Oswestry Disability Index and Medical Outcomes Study 36-Item Short-Form Health Survey. Several statistical methods were used for analyses of the data, and a p value of <0.05 was considered to be statistically significant. A total of 104 patients (80.62%) with PLD and 82 patients (81.19%) with MED were eligible for analyses, with a mean follow-up period of 6.64 ± 0.67 years and 6.42 ± 0.51 years, respectively. There were no significant differences between the two groups in age, number of lesions, major symptoms and physical signs, and radiological findings. According to the MacNab criteria, 75.96% in the PLD group and 84.15% in the MED group achieved excellent or good results, respectively, this was statistically significant (p = 0.0402). With the Oswestry Disability Index questionnaires, the average scores and minimal disability, respectively, were 6.97 and 71.15% in the PLD group and 4.89 and 79.27% in the MED group. Total average scores of Medical Outcomes Study 36-Item Short-Form Health Survey were 75.88 vs. 81.86 in PLD group vs. MED group (p = 0.0582). The cost and length of hospitalization were higher or longer in MED group, a statistically significant difference (both p < 0.0001). Long-term complications were observed in two patients (2.44%) in the MED group, no such complications were observed in the PLD group. Both PLD and MED show an acceptable long-term efficacy for treatment of lumbar disc herniation. Compared with MED patients, long-term satisfaction is slightly lower in the PLD patients; complications

    cem pacientes com diagnóstico de hérnia de disco lombar, comprovada com ressonância magnética e discografia evocativa positiva. Todos os pacientes nunca tinham passado por um tratamento cirúrgico e foi feito um seguimento por dois anos. RESULTADOS: os resultados foram classificados em bons, regulares e ruins. Foram encontrados bons resultados em 82 pacientes, regulares em 10 e ruins em 8. CONCLUSÕES: os resultados do tratamento da hérnia de disco lombar, com a endoscopia lateral e com o sistema YESS são, até o momento, similares àqueles com abordagem posterior aberta, mesmo que o tempo de recuperação e a capacidade sejam menores, assim como também o custo, pois é um procedimento ambulatório.INTRODUCTION: in the patients with lumbar disc herniation, who are candidates to surgical procedures, the open diskectomy has been the gold standard for many years. Nevertheless, the complications of this procedure, in which the medullar canal is invaded, have caused other means to be developed. One of them is the YESS system (Young Endoscopic Spine System. OBJECTIVE: to examine the results of one hundred patients with lumbar disc herniation, treated with the YESS system. METHODS: it was studied one hundred patients with lumbar disc herniation, which was proved with magnetic resonance imaging and discography, and their results were positive. None of the patients had ever undergone a surgical procedure; therefore, they were tracked for two years. RESULTS: results were classified into good, regular, and bad. In 82 patients good results were found, 10 were regular, and 8 were bad. CONCLUSIONS: the results of the treatment for a lumbar disc herniation with the YESS system are so far similar to open back surgery, even though the time of recovery, disability, and costs are lower because it is an ambulatory procedure.

The efficacy of nucleoplasty and identified variables that can predict pain relief for nucleoplasty was reported. Patients and methods: Between December 2013 and November 2015, 47 nucleoplasty procedures on 47 lumbar disks in 31 consecutive patients were performed. The outcome was evaluated using a visual analog scale (VAS score. Improvements of ≥50% in VAS scores were considered substantial pain relief. The variables associated with pain relief after nucleoplasty included: 1 age; 2 sex; 3 body mass index; 4 hyperintensity zone at the rear of the disk; 5 hypointensity of the disk; 6 Modic changes of the end plates; 7 spinal instability pain; and 8 discography results. Results: Twenty-one patients (67.7% experienced substantial pain relief. The most common side effects following nucleoplasty were soreness at the needle puncture site (64.5%, numbness in the lower leg (12.9%, and increased intensity of back pain (9.7%. All side effects were transient. Multivariate analysis revealed that the discography results were the most critical predictor for substantial pain relief of nucleoplasty (P=0.03. The sensitivity and specificity of discography were 92.8% and 62.5%, respectively. Conclusion: Discography results could improve the success rate of nucleoplasty in the treatment of disk degenerative LBP.

    This study aimed to compare the efficacy of muscle gap approach under a minimally invasive channel surgical technique with the traditional median approach.In the Orthopedics Department of Traditional Chinese and Western Medicine Hospital, Tongzhou District, Beijing, 68 cases of lumbar spinal canal stenosis underwent surgery using the muscle gap approach under a minimally invasive channel technique and a median approach between September 2013 and February 2016. Both approaches adopted lumbar spinal canal decompression, intervertebral disk removal, cage implantation, and pedicle screw fixation. The operation time, bleeding volume, postoperative drainage volume, and preoperative and postoperative visual analog scale (VAS) score and Japanese Orthopedics Association score (JOA) were compared between the 2 groups.All patients were followed up for more than 1 year. No significant difference between the 2 groups was found with respect to age, gender, surgical segments. No diversity was noted in the operation time, intraoperative bleeding volume, preoperative and 1 month after the operation VAS score, preoperative and 1 month after the operation JOA score, and 6 months after the operation JOA score between 2 groups (P > .05). The amount of postoperative wound drainage (260.90 ± 160 mL vs 447.80 ± 183.60 mL, P gap approach group than in the median approach group (P gap approach under a minimally invasive channel group, the average drainage volume was reduced by 187 mL, and the average VAS score 6 months after the operation was reduced by an average of 0.48.The muscle gap approach under a minimally invasive channel technique is a feasible method to treat long segmental lumbar spinal canal stenosis. It retains the integrity of the posterior spine complex to the greatest extent, so as to reduce the adjacent spinal segmental degeneration and soft tissue trauma. Satisfactory short-term and long-term clinical results were obtained.

    OBJECTIVE The object of this study was to determine the association between postoperative sagittal spinopelvic alignment and patient-rated outcome measures following decompression and fusion for lumbar degenerative spondylolisthesis. METHODS The authors identified a consecutive series of patients who had undergone surgery for lumbar degenerative spondylolisthesis between 2008 and 2012, with an average follow-up of 3 years (range 1-6 years). Surgery was performed to address the clinical symptoms of spinal stenosis, not global sagittal alignment. Sagittal alignment was only assessed postoperatively. Patients were divided into 2 groups based on a postoperative sagittal vertical axis (SVA) spondylolisthesis (p = 0.044), spondylolisthesis at the L3-4 level (p = 0.046), and multiple levels treated with fusion (p = 0.028) were more common among patients in the group with an SVA ≥ 50 mm. Patients with an SVA ≥ 50 mm had a worse SF-36 physical component summary (PCS) score (p = 0.018), a worse Oswestry Disability Index (ODI; p = 0.043), and more back pain (p = 0.039) than those with an SVA spondylolisthesis and multilevel fusion. The spinopelvic parameters differing between the < 50-mm and ≥ 50-mm groups included lumbar lordosis (LL; 56.4° ± 4.7° vs 49.8° ± 4.3°, respectively, p = 0.040) and LL < pelvic incidence ± 9° (51% vs 23.1%, respectively, p = 0.013) after controlling for type of surgical procedure. CONCLUSIONS Data in this study revealed that patient-rated outcome is influenced by the overall postoperative sagittal balance as defined by the SVA.

    Currently available approaches to osteoporosis treatment include application of antiresorptive and anabolic agents influencing bone tissue metabolism. The aim of the study was to present bone mineral density (BMD) changes of lumbar spine in osteoporotic patient treated with bisphosphonates such as ibandronic acid and pamidronic acid, and beta-hydroxy-beta-methylbutyrate (HMB). BMD and volumetric BMD (vBMD) of lumbar spine were measured during the 6 year observation period with the use of dual-energy X-ray absorptiometry (DEXA) and quantitative computed tomography (QCT). The described case report of osteoporotic patient with family history of severe osteoporosis has shown site-dependent response of bone tissue to antiosteoporotic treatment with bisphosphonates. Twenty-five-month treatment with ibandronic acid improved proximal femur BMD with relatively poor effects on lumbar spine BMD. Over 15-month therapy with pamidronic acid was effective to improve lumbar spine BMD, while in the proximal femur the treatment was not effective. A total of 61-week long oral administration with calcium salt of HMB improved vBMD of lumbar spine in the trabecular and cortical bone compartments when monitored by QCT. Positive effects of nearly 2.5 year HMB treatment on BMD of lumbar spine and femur in the patient were also confirmed using DEXA method. The results obtained indicate that HMB may be applied for the effective treatment of osteoporosis in humans. Further studies on wider human population are recommended to evaluate mechanisms influencing bone tissue metabolism by HMB.

    Full Text Available Objective. The authors present the clinical results obtained in patients who underwent interspinous fusion device (IFD implantation following posterior lumbar interbody fusion (PLIF. The purpose of this study is investigating the feasibility of IFD with PLIF in the treatment of lumbar spondylolisthesis. Methods. Between September 2013 and November 2014, 39 patients underwent PLIF and subsequent IFD (Romeo®2 PAD, Spineart, Geneva, Switzerland implantation. Medical records of these patients were retrospectively reviewed to collect relevant data such as blood loss, operative time, and length of hospital stay. Radiographs and clinical outcome were evaluated 6 weeks and 12 months after surgery. Results. All 39 patients were followed up for more than one year. There were no major complications such as dura tear, nerve injuries, cerebrospinal fluid leakage, or deep infection. Both interbody and interspinous fusion could be observed on radiographs one year after surgery. However, there were 5 patients having early retropulsion of interbody fusion devices. Conclusion. The interspinous fusion device appears to achieve posterior fixation and facilitate lumbar fusion in selected patients. However, further study is mandatory for proposing a novel anatomic and radiological scoring system to identify patients suitable for this treatment modality and prevent postoperative complications.

    We report a case of calcific tendinopathy of the gluteus medius initially misdiagnosed as a lumbar herniated intervertebral disc. It was successfully treated with barbotage under ultrasonographic guidance finally. A 56-year-old woman was referred to interventional pain clinic for right hip pain due to an L5-S1 disc herniation. Serial L5 and S1 spinal nerve root blocks and epidural steroid injections were administered. However, pain relief was sustained only for a very short period. Plain radiography of the right hip revealed a solid calcific nodule at adjacent to the insertion site of the gluteus medius tendon. Physical modalities and extracorporeal shock wave therapy failed to improve the pain. Therefore, we attempted ultrasound-guided barbotage of the calcification. Barbotage was performed twice serially and her pain was considerably improved. At 6-month follow-up, the calcification was completely resolved.

    Study Design Prospective cohort study with questionnaire. Purpose To compare the treatment outcome of nocturnal leg cramps in lumbar spinal canal stenosis (LSCS) patients on conservative treatment with historical surgical cohorts and to determine the sensitivity and specificity as well as positive predictive value and negative predictive value of knee flexion test suggested for LSCS patient. Overview of Literature True prevalence of nocturnal leg cramps in LSCS patients as well as the clinical outcome of its surgical treatment have been reported. Methods A questionnaire suggested from previous study with minor modifications was used in this study. Clinical data was collected. Knee flexion test was performed in two groups. Results The prevalence of nocturnal leg cramp was higher in the LSCS group compared to the control group (second group). In LSCS patients, 38 (88%) had improved leg cramps after the conservative treatment, 3 (6.97%) remained unchanged, and 2 (4.6%) had worsened leg cramps. Of the 43 patients, 21 (48.8%) had no disturbance to their activities of daily living. In the LSCS group, the sensitivity and specificity of the knee flexion test was 53.5% and 33.3%, respectively. The knee flexion test in the LSCS group had a positive predictive value and a negative predictive value of 65.71% and 23.1%, respectively. Conclusions Our study demonstrated that nocturnal leg cramps were significantly more frequent in LSCS patients than in the control group. PMID:25346815

    The objective of this study is to investigate the effects of acupuncture, core-stability exercises, and treadmill 12-minute walking exercises in treating patients with postsurgical lumbar disc herniation. A 34-year-old woman with a history lumbar disc prolapse who had undergone lumbar disc surgery on two different occasions was treated using acupuncture, core-stability exercises, and treadmill walking exercises three times per week for 12 weeks. The outcome measures used in this study were pain intensity, spinal range of movement, and general health. After 12 weeks of treatment, the patient had made improvement in terms of pain, which was reduced from 9/10 to 1/10. In a similar vein, the patient's general health showed improvement of >100% after 12 weeks of treatment. Pre-treatment scores of spinal flexion and left-side flexion, which measured 20 cm and 12 cm, respectively, increased to 25 cm and 16 cm after 12 weeks of treatment. This study showed that acupuncture, core-stability exercises, and treadmill walking exercises were useful in relieving pain, increasing spinal range of movement, and improving the health of a patient with postsurgical lumbar disc herniation.

    The application of tubular microscopes discectomy (TMD) was supposed to have similar or better results than conventional microdiscectomy (CMD). However, this conclusion had not been verified by sufficient evidence. Therefore, the focus of this meta-analysis was to assess the efficiency, safety, and clinical outcome of these 2 surgical procedures for treating lumbar disk herniation (LDH). PubMed, Embase, and Cochrane Collaboration Central databases were searched for studies which compared the results of TMD and CMD for the treatment of LDH up to July 2017. Data analysis was conducted using RevMan 5.3. A standardized electronic form of 17 predefined criteria from the Consort statement was used for the quality assessment. Eight randomized controlled trials (RCT) and 2 retrospective studies were included in this review, including 804 patients. The pooled analysis showed that there was no significant difference in operative time (P = .38), blood loss (P = .14), the length of hospital stay (P = .47), the rate of intraoperative complications (P = .79), postoperative complications (P = .16), dural tear (P = .87), the reoperation (P = .20), the short-term back visual analog scale (VAS) scores (P = .76), the long-term back VAS scores (P = .64), the short-term leg VAS scores (P = .09), the long-term leg VAS scores (P = .35), and the Oswestry disability index (ODI) scores (P = .41). The results of this meta-analysis demonstrate that TMD and CMD are both safe and effective surgical procedures which can be recommended for treating LDH. Additionally, the conclusion should be cautiously treated, because it was reached in the context of limited amount of studies and relatively small sample size. Therefore, future studies with good design and more large samples are required to validate this conclusion.

    Objective: To study the clinical results of Coflex and lumbar posterior decompression and fusion in the treatment of lumbar degenerative spondylolisthesis at L(4-5). Methods: Thirty-eight patients with Grade Ⅰ degenerative spondylolisthesis, from January 2008 to December 2011 in Beijing Chaoyang Hospital, Capital Medical University were reviewed, and patients were divided into two groups by randomness. Group A was treated with Coflex and group B with pedicle instrumentation and interbody fusion. Fifteen patients were included in group A, and 23 patients were included in group B. In group A, the average age was (56.3±9.1) years. In group B, the average age was (58.2±11.2) years. The clinical results were evaluated by visual analogue scale (VAS) and Oswestry disability index (ODI). Slip distance (SD) was measured before and after surgery, and the changes of intervertebral angle at index level and adjacent level were also recorded. Results: The follow-up period was 36 to 68 months, with the average of (39±14) months in the both groups. The operation time and bleeding volume of patients in group A were significantly less than that of group B ( P surgery, the difference at upper and below adjacent segment before and after surgery were statistically significant. Conclusions: Coflex interspinous dynamic stabilization system has same excellent clinical results as pedicle screw instrumentation and fusion surgery for the treatment of L(4-5) degenerative spondylolisthesis; no significant progression of spondylolisthesis been observed during more than 3 years follow-up, and no obvious adjacent segment degeneration has been found.

    To assess the outcome of surgical treatment in spondylolisthesis of lumbosacral region using Oswestry disability Index. The quasi-experimental study was conducted at the Combined Military Hospital, Rawalpindi from 2006 to 2013 and comprised surgically treated patients with spondylolisthesis. The patients with degenerative and isthmic types with follow-up of at least two years were included. A performa was designed for each patient and records were kept in a custom-built database. Oswestry disability index was used as the assessment tool and assessment was done pre-operatively, at 1, 3 and 6 months and then at 1 year and 2 years. There were 96 patients with mean pre-op Oswestry disability index score of 81.06% (range 42.22-100, SD ±11.99). L5-S1 was affected in 44 (45.83%) patients, L4-L5 in 30 (31.25%), L4-5-S1 in 7 (7.29%) and multi or high level was found in the rest of the cases. One level was involved in 77 (80.2%), 2 in 11 (11.45%), 3 in 7 (7.29%) and 4 in 1 (1.04%). The slip grade as per Meyerding grades was 1 in 31 (32.29%), II in 39 (40.62%), III in 19 (19.79%), IV in 5 (5.2%) and 2 (2.08%) had spondyloptosis. Mean follow-up was 42 months (range 24-63). Mean Oswestry disability score at 1 month was 38.51% (range 11- 62.22%, SD ±11.75); at 6 months 10.02% (range 0-40%, SD ±6.99); at 1 year 4.62% (range 0-24%, SD ±5.36) and at 2 years 4.21% (range 0-15%, SD ±4.2). Surgical treatment of spondylolisthesis gives excellent long-term result in most patients.

    Needle entry site localization remains a challenge for procedures that involve lumbar puncture, for example, epidural anesthesia. To solve the problem, we have developed an image classification algorithm that can automatically identify the bone/interspinous region for ultrasound images obtained from lumbar spine of pregnant patients in the transverse plane. The proposed algorithm consists of feature extraction, feature selection and machine learning procedures. A set of features, including matching values, positions and the appearance of black pixels within pre-defined windows along the midline, were extracted from the ultrasound images using template matching and midline detection methods. A support vector machine was then used to classify the bone images and interspinous images. The support vector machine model was trained with 1,040 images from 26 pregnant subjects and tested on 800 images from a separate set of 20 pregnant patients. A success rate of 95.0% on training set and 93.2% on test set was achieved with the proposed method. The trained support vector machine model was further tested on 46 off-line collected videos, and successfully identified the proper needle insertion site (interspinous region) in 45 of the cases. Therefore, the proposed method is able to process the ultrasound images of lumbar spine in an automatic manner, so as to facilitate the anesthetists' work of identifying the needle entry site.

    The pathophysiology of lumbar radiculopathy includes both mechanical compression and biochemical irritation of apposed neural elements. Inflammatory and immune cytokines have been implicated, induced by systemic exposure of immune-privileged intervertebral disc tissue. Surgical intervention provides improved symptoms and quality of life, but persistent postoperative neuropathic pain (PPNP) afflicts a significant fraction of patients. To compare the inflammatory and immune phenotypes among patients undergoing structural surgery for lumbar radiculopathy and spinal cord stimulation for neuropathic pain. Consecutive patients undergoing surgical intervention for lumbar radiculopathy or neuropathic pain were studied. Demographic data included age, gender, and VAS and neuropathic pain scores. Serum was evaluated for cytokine levels (IL-6, Il-17, TNF-α) and cellular content [white blood cell (WBC)/differential, lymphocyte subtypes]. The primary analysis differentiated molecular and cellular profiles between radiculopathy and neuropathic pain patients. Subgroup analysis within the surgical radiculopathy population compared those patients achieving relief of symptoms and those with PPNP. Heightened IL-6, Il-17, and TNF-α levels were observed for the lumbar radiculopathy group compared with the neuropathic pain group. This was complemented by higher WBC count and a greater fraction of Th17 lymphocytes among radiculopathy patients. In the lumbar discectomy subgroup, pain relief was seen among patients with preoperatively elevated IL-17 levels. Those patients with PPNP refractory to surgical discectomy exhibited normal cytokine levels. Differences in Th17 immune activation are seen among radiculopathy and neuropathic pain patients. These cellular and molecular profiles may be translated into biomarkers to improve patient selection for structural spine surgery. Copyright © 2017 by the Congress of Neurological Surgeons

    Lumbar fusion using the pedicle screw system is a popular operative procedure, with favorable clinical results and high fusion rates. However, the risk of adjacent segment disease after lumbar fusion is problematic. We report a complicated case of severe retrolisthesis at L3-4 level following dynamic interspinous process stabilization at L2-3 level and a fusion at L4-5 level. The radiological and clinical findings of this complication are discussed, and a review of the literature is presented.

    Objective: To investigate the stiffness of lumbar spine after the injury caused by percutaneous diskectomy and evaluate the efficiency of percutaneous lumbar diskectomy by biomechanical study. Methods: Four fresh lumbar specimens were used to analyse load-displacement curves in the intact lumbar spine and vertical disc-injured lumbar spine. The concepts of average flexibility coefficient (f) and standardized average flexibility coefficient (fs) were also introduced. Results: The load-displacement curves showed a good stabilization effect of the intact lumbar spine and disc-injured lumbar spine in flexion, extension, right and left bending. The decrease of anti-rotation also can be detected (P<0.05). Conclusion: In biomechanical study, percutaneous lumbar diskectomy is one of the efficiency methods to treat lumbar diac hernia

    Interbody fusion cages with integrated fixation components have become of interest due to their ability to provide enhanced post-operative stability and mitigate device migration. A recently approved anterior lumbar interbody fusion cage with integrated fixation anchors has yet to be compared in vitro to a standard polyetheretherketone cage when used in combination with an interspinous process clamp. Twelve human cadaveric lumbar segments were implanted at L4-L5 with a Solus interbody cage (n=6) or standard polyetheretherketone cage (n=6) following Intact testing and discectomy. Each cage was subsequently evaluated in all primary modes of loading after supplementation with the following posterior constructs: interspinous process clamp, bilateral transfacet screws, unilateral transfacet screw with contralateral pedicle screws, and bilateral pedicle screws. Range of motion results were normalized to Intact, and a two-way mixed analysis of variance was utilized to detect statistical differences. The Solus cage in combination with all posterior constructs provided significant fixation compared to Intact in all loading conditions. The polyetheretherketone cage also provided significant fixation when combined with all screw based treatments, however when used with the interspinous process clamp a significant reduction was not observed in lateral bending or axial torsion. Interbody cages with integrated fixation components enhance post-operative stability within the intervertebral space, thus affording clinicians the potential to utilize less invasive methods of posterior stabilization when seeking circumferential fusion. Interspinous process clamps, in particular, may reduce peri-operative and post-operative comorbidities compared to screw based constructs. Further study is necessary to corroborate their effectiveness in vivo. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Topping-off surgery is a newly-developed surgical technique which combines rigid fusion with an interspinous process device in the adjacent segment to prevent adjacent segment degeneration. There are few reports on Topping-off surgery and its rationality and indications remains highly controversial. Our study aims to investigate the short-term and mid-term clinical results of Topping-off surgery in preventing adjacent segment degeneration when mild or moderate adjacent segment degeneration existed before surgery. The 25 cases that underwent L5-S1 posterior lumbar interbody fusion (PLIF) + L4-L5 interspinous process surgeries between April 2008 and March 2010 formed Topping-off group. The 42 cases undergoing L5-S1 PLIF surgery formed PLIF group. Both groups matched in gender, age, body mass index and Pfirrmann grading (4 to 6). The patients were evaluated with visual analogue scale (VAS) and Japanese orthopaedic association (JOA) scores before surgery and in the last follow-up. Modic changes of endplates were recorded. The follow-up averaged 24.8 and 23.7 months. No symptomatic or radiological adjacent segment degeneration was observed. There was no significant difference in intraoperative blood loss or postoperative drainage. VAS and lumbar JOA scores improved significantly in both groups (t = 12.1 and 13.5, P adjacent segment degeneration, restrict the adjacent segment's ROM in extension and prevent excessive olisthesis of adjacent segment in both extension and flexion.

    This study evaluated the efficacy and safety of mini-open anterior debridement and lumbar interbody fusion in combination with posterior percutaneous fixation for single-level lumbar pyogenic spondylodiscitis. This is a retrospective study. Twenty-two patients with single-level lumbar pyogenic spondylodiscitis underwent mini-open anterior debridement and lumbar interbody fusion in combination with posterior percutaneous fixation via a modified anterior lumbar interbody fusion (ALIF) approach. Patients underwent follow-up for 24 to 38 months. Clinical data, etiological examinations, operative time, intraoperative blood loss, American Spinal Injury Association (ASIA) grade, Japanese Orthopaedic Association (JOA) lumbar function score, visual analog scale (VAS) score, Oswestry Disability Index (ODI), postoperative complications, and the bony fusion rate were recorded. The mean operative time was 181.1 ± 22.6 minutes (range 155-240 minutes). The mean intraoperative blood loss was 173.2 ± 70.1 ml (range 100-400 ml). Infection was found in lumbar vertebrae L2-3, L3-4, and L4-5 in 2, 6, and 14 patients, respectively. Bacterial cultures were positive in 15 patients, including 4 with Staphylococcus aureus, 6 with Staphylococcus epidermidis, 4 with Streptococcus, and 1 with Escherichia coli. Postoperative complications included urinary retention, constipation, and numbness in the thigh in 5, 3, and 2 patients, respectively. Compared with before surgery, the VAS scores and ODI were significantly lower at the final follow-up, the JOA scores were significantly higher, and the ASIA grades had improved. All patients achieved good intervertebral bony fusion. Mini-open anterior debridement and lumbar interbody fusion in combination with posterior percutaneous fixation via a modified ALIF approach results in little surgical trauma and intraoperative blood loss, acceptable postoperative complications, and is effective and safe for the treatment of single-level lumbar pyogenic

    The aim of this study is to report our 39 patients treated with anterior debridement and autologous iliac bone grafting with or without anterior instrumentation, which is the presumed treatment of choice for thoracic or lumbar spondylodiscitis.Our patients underwent surgical treatment of spondylodiscitis using anterior debridement and autologous iliac bone grafting with or without anterior instrumentation and were analyzed with a mean follow-up of 8 years (range, 2-11 years). Kaneda 2-rod system instrumentation was used in 12 patients, in total. Clinical outcomes were assessed by the Frankel grade. Radiographic fusion was characterized based on 3-dimensional computed tomography.Of the whole group, 20 patients suffered from tuberculous spondylodiscitis and 19 suffered from hematogenous spondylodiscitis. Pathogens responsible for pyogenic infection included Staphylococcus aureus (4 patients), Pseudomonas aeruginosa (3 patients), and Brucella melitensis (1 patient). Fifteen patients had thoracic involvement, 20 had lumbar involvement, and 4 had thoracolumbar junction involvement. Preoperative neurological deficits were noted in 13 of the 39 patients. In terms of Frankel grade, 8 patients have improved, 4 have remained the same, and 1 patient has worsened during the follow-up period. Imaging-documented fusion was achieved in 23 of 27 patients in the graft group (85% fusion rate) and 11 of 12 patients in the graft + Kaneda instrumentation group (91% fusion rate).There was no instrumentation failure, loosening, or graft-related complication such as slippage or fracture of the graft. This approach demonstrated a good recovery rate of neurological functions and a high fusion rate.

    Transpedicular screw (TPS) fixation in unstable thoracic and lumbar (TL) spine fractures remains technically difficult because of destroyed anatomical landmarks, unstable gross segments, and discrepancies in anatomic orientation using conventional anatomic landmarks, fluoroscopic guidance, or computed tomography (CT)-based navigation. In this study, we evaluated the safety and accuracy of TPS placement under intraoperative computed tomography (iCT) navigation in managing unstable TL spine fractures.From 2010 to 2013, we retrospectively reviewed the Spine Operation Registry records of patients who underwent posterior instrumented fusion to treat unstable TL spine fractures via the iCT navigation system. An unstable spine fracture was identified as AO/Magerl classification type B or type C.In all, 316 screws in 37 patients with unstable TL spine fractures were evaluated and involved 7 thoracic, 23 thoracolumbar junctional, and 7 lumbar fractures. The accuracy of TPS positioning in the pedicle without breach was 98% (310/316). The average number of iCT scans per patient was 2.1 (range 2-3). The average total radiation dose to patients was 15.8 mSv; the dose per single level exposure was 2.7 mSv. The TPS intraoperative revision rate was 0.6% (2/316) and no neurovascular sequela was observed. TPS fixation using the iCT navigation system obtained a 98% accuracy in stabilizing unstable TL spine fractures. A malplaced TPS could be revised during real-time confirmation of the TPS position, and no secondary operation was required to revise malplaced screws.The iCT navigation system provides accurate and safe management of unstable TL spine fractures. In addition, operating room personnel, including surgeons and nurses, did not need to wear heavy lead aprons as they were not exposed to radiation.

    Background To describe and assess clinical outcomes of the semi-circumferential decompression technique for microsurgical en-bloc total ligamentum flavectomy with preservation of the facet joint to treat the patients who have a lumbar spinal stenosis with degenerative spondylolisthesis. Methods We retrospectively analyzed the clinical and radiologic outcomes of 19 patients who have a spinal stenosis with Meyerding grade I degenerative spondylolisthesis. They were treated using the "semi-circumferential decompression" method. We evaluated improvements in back and radiating pain using a visual analogue scale (VAS) and the Oswestry Disability Index (ODI). We also evaluated occurrence of spinal instability on radiological exam using percentage slip and slip angle. Results The mean VAS score for back pain decreased significantly from 6.3 to 4.3, although some patients had residual back pain. The mean VAS for radiating pain decreased significantly from 8.3 to 2.5. The ODI score improved significantly from 25.3 preoperatively to 10.8 postoperatively. No significant change in percentage slip was observed (10% preoperatively vs. 12.2% at the last follow-up). The dynamic percentage slip (gap in percentage slip between flexion and extension X-ray exams) did not change significantly (5.2% vs. 5.8%). Slip angle and dynamic slip angle did not change (3.2° and 8.2° vs. 3.6° and 9.2°, respectively). Conclusions The results suggested that semi-circumferential decompression is a clinically recommendable procedure that can improve pain. This procedure does not cause spinal instability when treating patients who have a spinal stenosis with degenerative spondylolisthesis. PMID:26640630

    Clinical study of 14 patients with radiation colitis who were treated surgically at our clinic in the past 16-year period and a patient whose treatment was very difficult are reported. Primary lesions included 13 cervical carcinomas and one ovarian cancer. Ten cases received surgery combined with radiation and 4 did radiation. Radiation dose was 6055 rad on average. Latent time ranged from 6 months to 25 years with the average of 8 years and 9 months. No significant correlation between radiation dose and latent time was noted. Symptoms included obstruction and stenosis in 56% (8/14), hematoemesis in 46% (5/14), and fistula in 46% (5/14). All lesions presented as remarkably adhesion and stenosis, and resection with anastomosis was performed in 9 (64%), colostomy in 5 (46%), and urostomy in 2 (14%). Lumbar plasty was added in one case. A 65-year-old female patient who had undergone radiation therapy 13 years before had a rectal perforation and pelvic fistula. Abdominoperineal resection of the rectum and closure of the fistula by transferring the major gluteal muscle pedicle were performed. The patient is followed on ambulant basis for more than one year, and no evidence of recurrence has been observed. (author).

    Conservative treatment is a frequently used treatment modality for traumatic thoracolumbar fractures. However, not many studies evaluating radiological and clinical results of conservative treatment are found. The aim of this study was to determine the risk factors, and compression and kyphosis rates after 1 year in patients with AO type A thoracic, thoracolumbar, and lumbar fractures treated conservatively. Radiological and clinical results of 79 thoracolumbar fractures in 57 patients, who were treated conservatively, were evaluated one year after trauma. Fractures were classified according to thoracolumbar injury classification and severity (TLICS) score and AO spinal trauma classification system. Compression rate, wedge and kyphosis angles, and sagittal index were calculated in early and late periods after trauma. Female/male ratio was 25/32, and mean age was 41.7±16.7 years. They were followed for 15.2±4.9 months. Mean compression rates were 19.6% and 25.2%; wedge angles were 10.1 and 12.7 degrees; kyphosis angles were 5.82 and 8.9 degrees; and sagittal indexes were 8.01 and 10.13 in all patients just after trauma and after one year, respectively. Fractures in older patients ( > 60 years of age) and in patients with osteopenia or osteoporosis, located in the thoracolumbar junction, AO type A2 and A3 fractures, and solitary fractures had higher compression and kyphosis rates at last follow-up. Early mobilization without bed rest for stable thoracolumbar fractures according to the TLICS system is a good treatment option, and radiological and clinical results are usually acceptable. However, fractures in patients older than 60 years, those with osteoporosis or osteopenia, fractures located in the thoracolumbar junction, solitary fractures, and fractures in AO type A2 or A3, are more inclined to increase in compression and kyphosis and may require a closer follow-up.

    We prospectively assessed the diagnostic criteria of morphologic MRI study (MMS) and the accuracy of DWI and related ADC values (DWI-ADC) versus intervertebral disk volumetric analysis (IDVA) for predicting shrinkage of lumbar disk herniation treated with oxygen-ozone (O2-O3) diskolysis. Sixty-eight patients (36 men and 32 women; mean age 39) with lumbosciatica underwent O2-O3 diskolysis. The six-month MRI follow-up was performed with FSE-T2 and T2-fat, SE-T1 and DWI-weighted images. IDVA was determined using OsiriX(®). Diagnostic criteria and accuracy were evaluated with regards to DWI and related ADC in detecting response to ozone therapy. Fifty-eight of 68 patients had successful outcomes (responders), whereas ten patients showed unsatisfactory outcomes (non-responders). MMS showed that a centrally located herniated disk and grade 1 nerve root compression were more common in the responder group (p < 0.05). DWI-ADC and IDVA showed statistically significant shrinkage in the sixth month of follow-up (p < 0.05) with a mean ADC value reduction of 2.10 × 10(-3) mm(2)/s +/- 0.19 SD in the second month of follow-up (p < 0.05). DWI-ADC had an accuracy of 0.81 in detecting response to therapy around the second month of follow-up. DWI-ADC appear to be useful adjuncts to MMS in the follow-up of patients undergoing O2-O3 diskolysis.

    Cross-sectional study in patients with idiopathic scoliosis treated with spinal fusion. To measure lumbar spine mobility in the study population; determine low back pain intensity (LBPi), subjective perception of trunk flexibility (TF), and quality of life using validated outcome instruments; and investigate correlations of the lower instrumented vertebra (LIV) with TF, LBPi, and quality of life. The loss of range of motion resulting from spinal fusion might lead to low back pain, trunk rigidity, and a negative impact on quality of life. Nonetheless, these outcomes have not been conclusively demonstrated because lumbar mobility and LIV have not been correlated with validated outcome instruments. Forty-one patients (mean age, 27 y) with idiopathic scoliosis treated by spinal fusion (mean time since surgery, 135 mo) were included. Patients were assigned to 3 groups according to LIV level: group 1 (fusion to T12, L1, or L2) 14 patients; group 2 (fusion to L3) 13 patients, and group 3 (fusion to L4, L5, or S1) 14 patients. At midterm follow-up, patients completed the Scoliosis Research Society (SRS)-22 Questionnaire and Quality of Life Profile for Spine Deformities to evaluate perceived TF, and rated LBPi with a numerical scale. Lumbar mobility was assessed using a dual digital inclinometer. Group 3 (fusion to L4, L5, or S1) showed statistically significant differences relative to the other groups, with less lumbar mobility and poorer scores for the SRS subtotal (P = 0.003) and SRS pain scale (P = 0.01). Nevertheless, LBPi and TF were similar in the 3 groups. TF correlated with SRS-22 subtotal (r = -0.38, P = 0.01) and pain scale (r = -0.42, P = 0.007) scores, and with LBPi (r = 0.43, P = 0.005). LIV correlated moderately with lumbar mobility, health-related quality of life (SRS-22), and spinal pain (SRS-22 pain subscale), but not with intensity of pain in the lumbar area or perceived TF.

    The authors conducted a biomechanical study in which they compared the uses of the Rogers interspinous and the Lovely-Carl tension band wiring techniques for internal fixation of the cervical spine. An extensive biomechanical evaluation (stiffness in positive and negative rotations around the x, y, and z axes; range of motion in flexion-extension, bilateral axial rotation, and bilateral bending; and neutral zone in flexion-extension, bilateral axial rotation, and lateral bending to the right and to the left) was performed in two groups of intact calf cervical spines. After these initial tests, all specimens were subjected to a distractive flexion Stage 3 ligamentous lesion. Group 1 specimens then underwent surgical fixation by the Rogers technique, and Group 2 specimens underwent surgery by using the Lovely-Carl technique. After fixation, specimens were again submitted to the same biomechanical evaluation. The percentage increase or decrease between the pre- and postoperative parameters was calculated. These values were considered quantitative indicators of the efficacy of the techniques, and the efficacy of the two techniques was compared. Analysis of the findings demonstrated that in the spines treated with the Lovely-Carl technique less restriction of movement was produced without affecting stiffness, compared with those treated with the Rogers technique, thus making the Lovely-Carl technique clinically less useful.

    This paper presents the experimental results of a biomechanical evaluation in lumbar porcine specimens (L2-L4), instrumented with flexible polymer belts, under fatigue and tensile loading. The clinical effect called facetary arthrosis is evaluated. An experimental analysis was carried on 3 lumbar porcine specimens. In two of them, polyamide belts are fixed on the interspinous ligament from L2 to L4. Specimens are taken from pigs which are 6 month old. For the present work, the stiffness reduction of the spine and the biomechanical behaviour of the belts in conjunction with the interspinous ligament are evaluated. The purpose is to determine the failure conditions for the elements of the specimen (vertebral disk, supra and intraspinous ligament and vertebral body). Under static loading, which is the base line case, the elements of the specimen failed as a typical healthy structure. While in the fatigue combined with static loading, the element failed in different order. Additionally, the stiffness changed in accordance with the fatigue loading conditions. Because of the simplicity of this alternative technique, a high level of the structural integrity is preserved, as no holes are made on the spinous process in order to insert the fixation screws. Furthermore, there is a cost reduction.

    We evaluated the potential of MR sequences with Fat Saturation and gadolinium in patients with degenerative disease of the lumbar spine and low back pain, by studying both anterior and posterior elements of the lumbar spine. We examined 3323 patients (age range 15-78 years) presenting low back pain. We used T2-weighted sequences with Fat Saturation and in some selected cases (1063 patients, 32%) administered gadolinium using T1-weighted sequences with Fat Saturation. In particular we used gadolinium in the following cases: 1) presence of hyperintense areas on T2 weighted images with Fat Saturation in the osteo-articular and muscular-ligamentous structures of the lumbar spine; 2) Clinical-radiological discrepancy in patients without disc-root conflict and clinical suspicion of posterior vertebral compartment syndrome. We found degenerative-inflammatory changes in osteo-articular, ligamentous and muscular structures in 1063 patients: osteochondrosis, "aseptic discitis", facet joint effusion and synovitis, osteoarthritis, synovial cysts, spondylolysis, degenerative-inflammatory changes of the posterior ligaments (flava, interspinous and supraspinous ligaments) and posterior perispinal muscles. To improve diagnostic accuracy and allow correct therapeutic guidance, MR examination in patients with low back pain must evaluate both anterior and posterior elements of the lumbar spine. Our study indicates that T2 sequences with Fat Saturation and, in selected cases, gadolinium administration, better visualize or disclose degenerative-inflammatory changes in the lumbar spine, showing the active-inflammatory phase and extension of these processes which may not be depicted during a standard MR examination.

    To evaluate the rates of technical success, clinical success, and complications of fluoroscopy-guided lumbar cerebrospinal fluid drainage. This retrospective study was approved by the Institutional Review Board of our hospital, and informed consent was waived. Ninety-six procedures on 60 consecutive patients performed July 2008 to December 2013 were evaluated. The patients were referred for the fluoroscopy-guided procedure due to failed attempts at a bedside approach, a history of lumbar surgery, difficulty cooperating, or obesity. Fluoroscopy-guided lumbar drainage procedures were performed in the lateral decubitus position with a midline puncture of L3/4 in the interspinous space. The catheter tip was positioned at the T12/L1 level, and the catheter was visualized on contrast agent-aided fluoroscopy. A standard angiography system with a rotatable C-arm was used. The definitions of technical success, clinical success, and complications were defined prior to the study. The technical and clinical success rates were 99.0% (95/96) and 89.6% (86/96), respectively. The mean hospital stay for an external lumbar drain was 4.84 days. Nine cases of minor complications and eight major complications were observed, including seven cases of meningitis, and one retained catheter requiring surgical removal. Fluoroscopy-guided external lumbar drainage is a technically reliable procedure in difficult patients with failed attempts at a bedside procedure, history of lumbar surgery, difficulties in cooperation, or obesity.

    The objective of our study was to retrospectively compare the radiography and MRI findings of unilateral spondylolysis in the upper lumbar segment and in the lower lumbar segment and to consider how these radiologic findings can be applied in the diagnosis of unilateral spondylolysis. Thirty patients with unilateral lumbar spondylolysis were categorized into one of two groups according to the lumbar levels involved with pars interarticularis defects: group A (L1, L2, and L3) or group B (L4 and L5). On radiographs, we evaluated contour bulging of the affected pars interarticularis, reactive sclerosis in the contralateral pedicle, anterolisthesis of the involved vertebra, and deviation of the spinous process. On MRI, we assessed pseudoarticulation of the pars interarticularis defect, uneven distribution of posterior epidural fat, the interspinous distance between adjacent segments, facet and disk degeneration in adjacent segments, and other anomalous changes. Among the 63 patients with unilateral spondylolysis, the upper lumbar segment was involved in 29 and the lower lumbar segment, in 34. Group A often displayed contour bulging of the affected pars interarticularis, reactive sclerosis of the contralateral pedicle, and contralateral deviation of the spinous process, all of which were easily detectable on radiography. Group B frequently showed anterolisthesis, pseudoarticulation of the pars interarticularis defect, adjacent facet-disk degeneration, and other anomalous changes that were well observed on MRI. Unilateral lumbar spondylolysis displayed radiologic differences in morphology of the isthmic defect itself and in ancillary findings of the adjacent structures based on the segment involved. Recognition of different ancillary features of unilateral spondylolysis with the use of a feasible diagnostic tool can be helpful for the diagnosis of cases in which a direct sign of isthmic defect is equivocal.

    Spontaneous infectious spondylodiscitis is a rare, but serious disease with the risk of progressive neurological impairment. The surgical approach to spontaneous infectious spondylodiscitis is in most cases an anterior debridement and fusion, often in staged surgeries. Here we report a case of single-stage posterior debridement and posterior instrumented fusion in combination with an injectable calcium sulfate/hydroxyapatite composite eluting gentamicin. A 59-year-old Caucasian man presented with a 6-week history of lumbar pain without sensory or motor disorders of his lower extremities. A magnetic resonance imaging scan of his lumbar spine in T2-weighted sequences showed a high signal of the intervertebral disc L4/L5 and in T1-weighted sequences an epidural abscess at the posterior wall of L4. Additional computed tomography imaging revealed osteolytic destruction of the base plate of L4 and the upper plate of L5. Antibiotic therapy was started with intravenous ciprofloxacin and clindamycin. We performed a posterior debridement via a minimally invasive approach, a posterior percutaneous stabilization using transpedicular screw-rod instrumentation and filled the intervertebral space with an injectable calcium sulfate/hydroxyapatite composite which elutes a high concentration of gentamicin. The patient's lower back pain improved quickly after surgery and no recurrence of infection has been noticed during the 1-year follow-up. Computed tomography at 11 months shows complete bony fusion of L4 and L5. An injectable calcium sulfate/hydroxyapatite composite releasing a high level of gentamicin can support the surgical treatment of spondylodiscitis in combination with posterior debridement and transpedicular screw-rod instrumentation.

    To report our results about minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) with bilateral pedicle screw fixation, in patients with degenerative lumbosacral spine disease. To describe the indications, surgical technique and results of a consecutive series of 40 patients undergone MI-TLIF. Despite the limited number of clinical studies, published data suggest tremendous potential advantages of this technique. Forty patients with radiological findings of degenerative lumbosacral spine disease were undergone MI-TLIF between July 2012 and January 2015. Clinical outcomes were assessed by means of Oswestry Disability Index (ODI) and Health Survey Scoring (SF36) before surgery and at first year follow-up. Furthermore, the following parameters were retrospectively reviewed: age, sex, working activity, body mass index (BMI), type of degenerative disease, number of levels of fusion, operative time, blood loss, length of hospital stay. Average operative time was of 230 minutes, mean estimated blood loss 170 mL, average length of hospital stay 5 days. The ODI improved from a score of 59, preoperatively, to post-operative score of 20 at first year follow-up. Average SF36 score increased from 36 to 54 (Physical Health) and from 29 to 50 (Mental Health) at first year outcome evaluation. MI-TLIF with bilateral pedicle screw fixation is an excellent choice for selected patients suffering from symptomatic degenerative lumbosacral spine disease, especially secondary to recurrent disk herniations.

    The most common cause of poor outcome following lumbar disc surgery is recurrent herniation. Recurrence has been noted in 5% to 15% of patients with surgically treated primary lumbar disc herniation. There have been many studies designed to determine the risk factors for recurrent lumbar disc herniation. In this study, we retrospectively analysed the influence of disc degeneration, endplate changes, surgical technique, and patient's clinical characteristics on recurrent lumbar disc herniation. Patients who underwent primary single-level L4-L5 lumbar discectomy and who were reoperated on for recurrent L4-L5 disc herniation were retrospectively reviewed. All these operations were performed between August 2004 and September 2009 at the Neurosurgery Department of Ataturk Education and Research Hospital in Ankara, Turkey. During the study period, 126 patients were reviewed, with 101 patients underwent primary single-level L4-L5 lumbar discectomy and 25 patients were reoperated on for recurrent L4-L5 disc herniation. Preoperative higher intervertebral disc height (Pdisc herniation had preoperative higher disc height and higher body mass index. Modic endplate changes had a higher tendency for recurrence of lumbar disc herniation. Well-planned and well-conducted large-scale prospective cohort studies are needed to confirm this and enable convenient treatment modalities to prevent recurrent disc pathology.

    The study design included an in vivo laboratory study. The objective of the study is to quantify the kinematics of the lumbar spinous processes in asymptomatic patients during un-restricted functional body movements with physiological weight bearing. Limited data has been reported on the motion patterns of the posterior spine elements. This information is necessary for the evaluation of traumatic injuries and degenerative changes in the posterior elements, as well as for improving the surgical treatment of spinal diseases using posterior procedures. Eight asymptomatic subjects with an age ranging from 50 to 60 years underwent MRI scans of their lumbar segments in a supine position and 3D models of L2-5 were constructed. Next, each subject was asked to stand and was positioned in the following sequence: standing, 45 degrees flexion, maximal extension, maximal left and right twisting, while two orthogonal fluoroscopic images were taken simultaneously at each of the positions. The MRI models were matched to the osseous outlines of the images from the two orthogonal views to quantify the position of the vertebrae in 3D at each position. The data revealed that interspinous process (ISP) distance decreased from L2 to L3 to L4 to L5 when measured in the supine position; with significantly higher values at L2-3 and L3-4 compared with L4-5. These differences were not seen with weight-bearing conditions. During the maximal extension, the ISP distance at the L2-3 motion segment was significantly reduced, but no significant changes were detected at L3-4 and L4-5. During flexion the ISP distances were not significantly different than those measured in the MRI position at all segments. Going from the left to right twist positions, the L4-5 segment had greater amounts of ISP rotation, while all segments had similar ranges of translation in the transverse plane. The interspinous process distances were dependent on body posture and vertebral level.

    Despite various treatments to control intracranial pressure (ICP) after brain injury, patients may present a late onset of high ICP or a poor response to medications. External lumbar drainage (ELD) can be considered a therapeutic option if high ICP is due to communicating external hydrocephalus. We aimed at describing the efficacy and safety of ELD used in a cohort of traumatic or non-traumatic brain-injured patients. In this multicentre retrospective analysis, patients had a delayed onset of high ICP after the initial injury and/or a poor response to ICP treatments. ELD was considered in the presence of radiological signs of communicating external hydrocephalus. Changes in ICP values and side effects following the ELD procedure were reported. Thirty-three patients with a median age of 51 years (25-75th percentile: 34-61 years) were admitted after traumatic (n = 22) or non-traumatic (n = 11) brain injuries. Their initial Glasgow Coma Scale score was 8 (4-11). Eight patients underwent external ventricular drainage prior to ELD. Median time to ELD insertion was 5 days (4-8) after brain insult. In all patients, ELD was dramatically effective in lowering ICP: 25 mmHg (20-31) before versus 7 mmHg (3-10) after (p effects such as pupil changes or intracranial bleeding after the procedure. One patient developed an ELD-related infection. These findings indicate that ELD may be considered potentially effective in controlling ICP, remaining safe if a firm diagnosis of communicating external hydrocephalus has been made.

    Background. In a group of patients treated surgically for stenosis in the lumbar spine, we compared the pre-operative nature of the pathology of the intervertebral disc as measured by MRI to the treatment outcome. Material and methods. In 30 persons ranging in age from 39 to 68 who reported at least 60% subjective improvement in quality of life after surgery (wide decompression of the spinal canal in the lumbar segment, spondylodesis, transpedicular fixation) the character of the discopathy was evaluated by MRI. Results. In MRI studies from the study group, feature of dehydratation and protrusion of the nucleus pulposus occurred among all patients, while the most common clinical symptom was neurogenic claudication. Non-removal of intervertebral discs protruding less than 6 mm into the lumen of the spinal canal did not cause worse outcome. Conclusion. In this group of patients treated surgically for lumbar stenosis with wide decompression, the fact that a slight protrusion of the intervertebral disc (prolapse <6mm) persists after surgery, in the absence of conflict between the disc and nerve elements, has no influence on treatment outcome.

    To investigate the effect of treating degenerative lumbar spondylolisthesis by transforaminal lumbar interbody fusion with microendoscopic surgery. From Jan. 2006 to Jan. 2009, one hundred fifty patients who underwent transforaminal lumbar interbody fusion with microendoscopic surgery were analyzed retrospectively. The diagnosis was degenerative lumbar spondylolisthesis in 84 cases of grade I, and 66 cases of grade II. There were 88 males and 62 females. Preoperatively, at 1 week and 3 months postoperatively, the pain was evaluated with visual analogue scale (VAS) scoring system and therapeutic effect was observed with modified Prolo scoring system. In complications, dural tear happened in 3 cases, biological glues were used for dural tear sealing and neither cerebrospinal fluid leak was found. One case suffered from intervertebral Infection and muscle weakness of foot was found in one case, either was cured after symptomatic treatment. Operative time averaged 160 minutes (120-280 min). Estimated blood loss averaged 210 ml (100-450 ml). The postoperative follow-up ranged from 6 to 36 months (averaged 15.2 months). Preoperatively,at 1 week and 3 months postoperatively, VAS scores were respectively 7.9 +/- 2.1, 2.2 +/- 0.6, 3.2 +/- 1.1 (P surgery transforaminal lumbar interbody fusion technique is indicated for lumbar vertebral instability, localized intervertebral disc disorder and lumbar spondylolisthesis with stenotic nerve root or tube below grade II. This technique has advantages of minimal invasion and early functional recovery.

    The purpose of this study was to compare self-reported pain and "improvement" of patients with symptomatic, magnetic resonance imaging-confirmed, lumbar disk herniations treated with either high-velocity, low-amplitude spinal manipulative therapy (SMT) or nerve root injections (NRI). This prospective cohort comparative effectiveness study included 102 age- and sex-matched patients treated with either NRI or SMT. Numerical rating scale (NRS) pain data were collected before treatment. One month after treatment, current NRS pain levels and overall improvement assessed using the Patient Global Impression of Change scale were recorded. The proportion of patients, "improved" or "worse," was calculated for each treatment. Comparison of pretreatment and 1-month NRS scores used the paired t test. Numerical rating scale and NRS change scores for the 2 groups were compared using the unpaired t test. The groups were also compared for "improvement" using the χ(2) test. Odds ratios with 95% confidence intervals were calculated. Average direct procedure costs for each treatment were calculated. No significant differences for self-reported pain or improvement were found between the 2 groups. "Improvement" was reported in 76.5% of SMT patients and in 62.7% of the NRI group. Both groups reported significantly reduced NRS scores at 1 month (P = .0001). Average cost for treatment with SMT was Swiss Francs 533.77 (US $558.75) and Swiss Francs 697 (US $729.61) for NRI. Most SMT and NRI patients with radicular low back pain and magnetic resonance imaging-confirmed disk herniation matching symptomatic presentation reported significant and clinically relevant reduction in self-reported pain level and increased global perception of improvement. There were no significant differences in outcomes between NRI and SMT. When considering direct procedure costs, the average cost of SMT was slightly less expensive.

    The purpose of this study was to evaluate whether specific MRI features, such as axial location and type of herniation, are associated with outcomes of symptomatic lumbar disc herniation patients treated with spinal manipulation therapy (SMT). MRI and treatment outcome data from 68 patients were included in this prospective outcomes study. Pain numerical rating scale (NRS) and Oswestry physical disability questionnaire (OPDQ) levels were measured at baseline. The Patients Global Impression of Change scale, the NRS and the OPDQ were collected at 2 weeks, 1, 3, 6 months and 1 year. One radiologist and 2 chiropractic medicine master's degree students analyzed the MRI scans blinded to treatment outcomes. κ statistics assessed inter-rater reliability of MRI diagnosis. The proportion of patients reporting relevant improvement at each time point was compared based on MRI findings using the chi-square test. The t test and ANOVA compared the NRS and OPDQ change scores between patients with various MRI abnormalities. A higher proportion of patients with disc sequestration reported relevant improvement at each time point but this did not quite reach statistical significance. Patients with disc sequestration had significantly higher reduction in leg pain at 1 month compared to those with extrusion (P = .02). Reliability of MRI diagnosis ranged from substantial to perfect (K = .733-1.0). Patients with sequestered herniations treated with SMT to the level of herniation reported significantly higher levels of leg pain reduction at 1 month and a higher proportion reported improvement at all data collection time points but this did not reach statistical significance.

    Full Text Available Low back pain and degenerative disc disease are a significant cause of pain and disability worldwide. Advances in regenerative medicine and cell-based therapies, particularly the transplantation of mesenchymal stem cells and intervertebral disc chondrocytes, have led to the publication of numerous studies and clinical trials utilising these biological therapies to treat degenerative spinal conditions, often reporting favourable outcomes. Stem cell mediated disc regeneration may bridge the gap between the two current alternatives for patients with low back pain, often inadequate pain management at one end and invasive surgery at the other. Through cartilage formation and disc regeneration or via modification of pain pathways stem cells are well suited to enhance spinal surgery practice. This paper will systematically review the current status of basic science studies, preclinical and clinical trials utilising cell-based therapies to repair the degenerate intervertebral disc. The mechanism of action of transplanted cells, as well as the limitations of published studies, will be discussed.

The patients in Group A (24 patients underwent long-segment instrumentation laminectomy with pedicle screw-rod fixators for neural decompression. In Group B (29 patients, the patients underwent long-segment instrumentation laminectomy with pedicle screw-rod fixators for neural decompression evacuating of the ruptured disc and inserting of a bone graft into the evacuated disc space for interbody fusion. The mean time between injury and operation was 4.1 days (range 2-15 days. The clinical, radiologic and complication outcomes were analyzed retrospectively.Periodic follow-ups were carried out until an affirmative union or treatment failure took place. A progressive kyphosis angle larger than 10°, loss of disc height, pseudoarthrosis, recurrence of dislocation or subluxation, or instrument failure before fusion were considered treatment failures. Treatment failures were detected in 13 cases in Group A (failure rate was 54.2%. In Group B, there were 28 cases in which definitive bone fusion was demonstrated on CT scans, and CT scans of the other cases demonstrated undefined pseudoarthrosis without hardware failure. There were statistically significant differences between the two groups (p0.05 Fisher's exact test.Intervertebral disc damage is a common characteristic in type B and C spinal fracture-dislocation injuries. The damaged intervertebral disc should be removed and substituted with a bone graft because reserving the damaged disc in situ increases the risk of treatment failure.

    The aim of this article is to introduce a technique for lumbar intervertebral fusion that incorporates mobile microendoscopic discectomy (MMED) for lumbar degenerative disc disease. Minimally invasive transforaminal lumbar interbody fusion is frequently performed to treat degenerative diseases of the lumbar spine; however, the scope of such surgery and vision is limited by what the naked eye can see through the expanding channel system. To expand the visual scope and reduce trauma, we perform lumbar intervertebral fusion with the aid of a MMED system that provides a wide field through freely tilting the surgical instrument and canals. We believe that this technique is a good option for treating lumbar degenerative disc disease that requires lumbar intervertebral fusion. © 2016 Chinese Orthopaedic Association and John Wiley & Sons Australia, Ltd.

    Full Text Available Lumbar stenosis is an increasingly common pathological condition that is becoming more frequent with increasing mean life expectancy, with high costs for society. It has many causes, among which degenerative, neoplastic and traumatic causes stand out. Most of the patients respond well to conservative therapy. Surgical treatment is reserved for patients who present symptoms after implementation of conservative measures. Here, a case of severe stenosis of the lumbar spine at several levels, in a female patient with pathological and surgical antecedents in the lumbar spine, is presented. The patient underwent two different decompression techniques within the same operation.

    2013-12-27

    Pain catastrophizing, appraisals of pain control, styles of coping, and social support have been suggested to affect functioning in patients with low back pain. We investigated the relation of chronic pain coping strategies to psychological variables and clinical data, in patients treated surgically due to lumbar disc herniation and coexisting spondylotic changes. The average age of study participants (n=90) was 43.47 years (SD 10.21). Patients completed the Polish versions of the Chronic Pain Coping Inventory-42 (PL-CPCI-42), Beck Depression Inventory (BDI-PL), Coping Strategies Questionnaire (CSQ-PL), Beliefs about Pain Control Questionnaire (BPCQ-PL), and Roland-Morris Disability Questionnaire (RMQ-PL). In the PL-CPCI-42 results, resting, guarding and coping self-statements were frequently used as coping strategies (3.96 SD 1.97; 3.72 SD 1.72; 3.47 SD 2.02, respectively). In the CSQ-PL domains, catastrophizing and praying/hoping were frequently used as coping strategies (3.62 SD 1.19). The mean score obtained from the BDI-PL was 11.86 SD 7.23, and 12.70 SD 5.49 from the RMDQ-PL. BPCQ-PL results indicate that the highest score was in the subscale measuring beliefs that powerful others can control pain (4.36 SD 0.97). Exercise correlated significantly with beliefs about internal control of pain (rs=0.22). We identified associations between radiating pain and guarding (p=0.038) and between sports recreation and guarding (p=0.013) and task persistence (p=0.041). Back pain characteristics, depressive mood, disability, and beliefs about personal control of pain are related to chronic LBP coping styles. Most of the variables related to advancement of degenerative changes were not associated with coping efforts.

    The efficacy of physical therapy for patients with lumbar spinal stenosis (LSS) has been reported only for the short term, and few reports have compared outcomes of surgical treatment with nonsurgical treatment after physical therapy. The purpose of this study was to assess 2-year outcomes of LSS patients treated with surgery or under follow-up observation after physical therapy for 6 weeks. Patients presenting with neurogenic claudication, radiologically-confirmed central LSS affecting both legs and refractory symptoms to pharmacotherapy of more than 3 months were enrolled. Patients were treated with manual therapy, stretching and strengthening exercises, and body weight-supported treadmill walking once a week for 6 weeks. Clinical outcomes were measured using the Zurich Claudication Questionnaire (ZCQ), visual analog scale of low back pain, leg pain, and numbness, the Japanese Orthopedic Association Back Pain Evaluation Questionnaire and the SF-36. Two years after physical therapy, patients were classified into the observation group (Group I) or the surgery group (Group II), whose patients failed to respond to physical therapy and wanted to undergo surgery. Thirty-eight patients were enrolled; 28 had complete data at 2 years: 21 and 7 in Groups I and II, respectively. Group II had a higher body mass index (BMI) than Group I. There were no significant differences in clinical outcomes at baseline. Six weeks after physical therapy, Group I had significantly better outcomes for symptom severity and physical function on the ZCQ subscales, physical functioning and bodily pain on the SF-36 subscales. These outcomes in Group I were maintained or improved and did not differ significantly between groups at 2-years. However, the physical function on the ZCQ subscales was improved in Group II more than those in Group I (mean difference -0.6; 95% CI: -1.2 to -0.03, P < 0.05) at 2 years. At 2 years, the outcomes except for the change in physical function score in the ZCQ

    The identification of the epidural space, insertion of an epidural catheter and lumbar puncture are advanced technical skills that can be challenging to teach to novice anaesthetists. The M43B Lumbar puncture simulator-II (Limbs & Things Ltd., Sussex Street, Bristol, UK) is a teaching aid designed for epidural and spinal insertion. The aim of this study was to determine if experienced anaesthetists thought this simulator may be a useful tool for training novice anaesthetists in these procedures. Experienced anaesthetists performed an epidural insertion followed by a lumbar puncture procedure on the simulator model. Various aspects of both epidural and lumbar puncture insertions were scored by the anaesthetists for likeness to a real patient using a Likert scale (0--strongly disagree; 1--disagree; 2--neither agree nor disagree; 3--agree; 4--strongly agree). The simulator was found to be life-like for most aspects of epidural insertion. Median (IQR [range]) scores were: iliac crests 3.0 (3.0-3.2 [3-4]); spinous processes 3.0 (3.0-3.2 [2-4]); skin puncture 3.0 (3.0-3.0 [1-4]); subcutaneous tissues 3.0 (2.7-3.0 [1-4]); and loss of resistance 3.0 (3.0-4.0 [3-4]). The scores for supraspinous ligament 2.0 (1.0-3.0 [0-3]), interspinous ligament 2.5 (1.7-3.0 [0-3]) and ligamentum flavum 2.0 (1.0-3.0 [0-4]) were borderline for life-likeness. The volunteers found threading of the epidural catheter difficult and rated it unlike a real patient (score 1.0 (0.2-2.0 [0-3])). During lumbar puncture, dural puncture scored 3.0 (3.0-4.0 [2-4]) and intrathecal injection scored 2.5 (1.0-3.0 [1-4]). However, the overall impression was that the simulator could be a useful tool for training of both epidurals (score 3.0 (3.0-4.0 [3-4])) and spinals (score 3.0 (3.0-3.5 [2-4])). © 2011 The Authors.

    2016-03-01

    Full Text Available ABSTRACT Objectives: To demonstrate the recovery of lumbar sagittal pelvic alignment and sagittal pelvic balance after surgical reduction of lumbar spondylolisthesis and establish the benefits of the surgery for reduction and fixation of the lumbar spondylolisthesis with 360o circumferential arthrodesis for 2 surgical approaches by clinical and functional evaluation. Method: Eight patients with lumbar spondylolisthesis treated with surgical reduction and fixation of listhesis and segmental circumferential fusion with two surgical approaches were reviewed. They were evaluated before and after treatment with Oswestry, Visual Analogue for pain and Odom scales, performing radiographic measurement of lumbar sagittal alignment and pelvic sagittal balance with the technique of pelvic radius. Results: Oswestry scales and EVA reported improvement of symptoms after treatment in 8 cases; the Odom scale had six outstanding cases reported. The lumbar sagittal alignment presented a lumbosacral lordosis angle and a lumbopelvic lordosis angle reduced in 4 cases and increased in 4 other cases; pelvic sagittal balance increased the pelvic angle in 4 cases and decreased in 3 cases and the sacral translation of the hip axis to the promontory increased in 6 cases. Conclusion: The surgical procedure evaluated proved to be useful by modifying the lumbar sagittal alignment and the pelvic balance, besides reducing the symptoms, enabling the patient to have mobility and movement and the consequent satisfaction with the surgery.

    Seventeen patients with lytic lumbar spondylolisthesis (Meyerding grade I-II) and radicular symptoms were examined by epidurography in addition to radiculomyelography before surgical treatment. Epidurography is considered more suitble than radiculomyelogrphy for assessing this condition because narrowing of the epidural space and compression of the nerve roots, due to osteofibrous changes at the lysis, are more consistently demonstrated.

    Osteoporotic patients can present with either single or multiple fractures secondary to repeated falls and progressive osteoporosis. Multiple fractures often lead to additional spinal deformity and are a sign of more severe osteoporosis. In the thoracic spine, multiple fractures are associated with the development of gradual thoracic kyphosis but neurologic deficits are uncommon. In the lumbar spine, patients with multiple lumbar fractures have more constant lumbar pain, may have symptoms related to concurrent lumbar stenosis or degenerative scoliosis, and may present with radiculopathy, especially with fractures at L4 and L5. In a review of a series of patients with recurrent multiple lumbar fractures or 'cascading' fractures, it was found that all the patients were female, had severe osteoporosis, often untreated, had a previous history of multiple previous thoracic and lumbar fractures, and all had associated scoliotic spinal deformities ranging from 6 o to 50 o . It was found that if the curve progressed and the greater the degree of curvature, the more frequently subsequent multiple fractures developed, leading to recurrent acute episodes of pain. Forty percent also had additional sacral insufficiency fractures, an unusually high percentage. Biomechanically, the lumbar spine is both more mobile and supports a larger portion of the spinal load compared to the thoracic spine. The existence or worsening of a lumbar spinal deformity from degenerative lumbar scoliosis shifts the mechanical forces more to one side on already weakened osteoporotic lumbar vertebrae and sacrum, leading to an increased incidence of these fractures. Because of the chronic and uneven lower lumbar spinal load with severe vertebral osteoporosis in certain patients with repeat lumbar fractures and worsening degenerative lumbar scoliosis, there may be a rationale to add preventive vertebroplasty at adjacent vertebral endplates when treating acute recurrent lumbar fractures to decrease the

    We studied the lumbar spines of 117 adults (39 women and 78 men) with spondylolysis unrelated to low back pain using multidetector computed tomography (CT). Of the 117 subjects with spondylolysis, including five with multiple-level spondylolysis, there were 124 vertebrae with spondylolysis. In adult lumbar spines with unilateral spondylolysis, there was no significant difference between the incidence of spondylolisthesis in female and male subjects. However, in those with bilateral spondylolysis, there was a significantly higher incidence of spondylolisthesis in female subjects (90.9%) than in males (66.2%). Furthermore, females with bilateral spondylolysis had significant more slippage than males. Lumbar index and lumbar lordosis were not significantly different between male and female subjects, and did not significantly correlate with slippage. In conclusion, to treat acute spondylolysis in adolescents, it is important to obtain bony union at least unilaterally, especially in female subjects, to prevent further slippage.

    This study investigated the therapeutic effect of percutaneous endoscopic lumbar discectomy on lumbar disc herniation, and explored its effect on oxidative stress in patients with lumbar disc herniation. One hundred and ten patients with lumbar disc herniation were selected in The Affiliated People's Hospital of Shanxi Medical University from May 2015 to May 2016. Patients were divided into control group (n=50) and observation group (n=60) according to different surgical methods. Patients in control group were subjected to traditional open discectomy, while patients in observation group were treated with percutaneous endoscopic lumbar discectomy. Surgical-related indicators, ODI and VAS scores before and 3 months after surgery, serum inflammatory factors and oxidative stress indicators were compared between 2 groups. There was no significant difference in operation time between the groups. Blood loss, incision size and time of bed rest in observation group were better than those in control group (P0.05). Levels of serum inflammatory factors TNF-α and CRP and oxidative stress indicators MDA and MPO were significantly lower and levels of oxidative stress indicators SOD and TAC were significantly higher in observation group than in control group (Pdisc herniation with percutaneous endoscopic lumbar discectomy has the advantages of small trauma, less blood loss and fast recovery, and can effectively improve the dysfunction, reduce pain and serum levels of inflammatory factors, and improve the levels of oxidative stress indicators, thereby improving the surgical results. Thus, this method should be considered for wide-use.

    The problems at the level of intervertebral discs are producing dysfunctions and important functional regression at the level of lumbar column, at a stage at which the patient could remain blocked in an anterior or lateral flexion position or producing an antalgic position of scoliosis that could incapacitate the patient to perform activities of daily living. The medical rehabilitation, in such cases, must seek not only the relief of local pain through different methods of obtaining it, but also the functional reeducation of the intervertebral articulations through specific analytical mobilization in order to achieve the biomechanical harmonization of the rachis. We report the case study of a 66 year-old patient who presented to our clinic for medical consult and physical therapy when he was diagnosed with discharthrosis, hyperalgic lumbar multileveled radiculopathy at L4-L5 and L5-S1. The lumbar x-ray showed osteophytes, disc narrowing at the level of L5-S1 and inter-apophysis arthrosis. The clinical examination revealed difficulty walking with pain in the right sacroiliac articulations and right sciatic emergence with plantar paraesthesia. The patient developed pain induced scoliosis on the right side that restricted the lumbar range of motion and prevented the right flexion blocking him into an left flexion, any attempt of straightening inducing pain. The condition was treated using specific analytical lumbar mobilization for the realignment of the vertebrae complex. In this case study, we found that functional reeducation in cases of pain induced deviations of the rachis of the column should be centered on the harmonization of inadequate pressure and position of the complex intervertebral articulations.

    2015-01-01

    Lumbar disc herniation is the most common diagnosis among the degenerative abnormalities of the lumbar spine (affecting 2 to 3% of the population), and is the principal cause of spinal surgery among the adult population. The typical clinical picture includes initial lumbalgia, followed by progressive sciatica. The natural history of disc herniation is one of rapid resolution of the symptoms (four to six weeks). The initial treatment should be conservative, managed through medication and physiotherapy, sometimes associated with percutaneous nerve root block. Surgical treatment is indicated if pain control is unsuccessful, if there is a motor deficit greater than grade 3, if there is radicular pain associated with foraminal stenosis, or if cauda equina syndrome is present. The latter represents a medical emergency. A refined surgical technique, with removal of the extruded fragment and preservation of the ligamentum flavum, resolves the sciatic symptoms and reduces the risk of recurrence over the long term.

    Low back pain is a frequent condition that results in substantial disability and causes admission of patients to neurosurgery clinics. To evaluate and present the therapeutic outcomes in lumbar disc hernia (LDH) patients treated by means of a conservative approach, consisting of bed rest and medical therapy. This retrospective cohort was carried out in the neurosurgery departments of hospitals in Kahramanmaraş city and 23 patients diagnosed with LDH at the levels of L3-L4, L4-L5 or L5-S1 were enrolled. The average age was 38.4 ± 8.0 and the chief complaint was low back pain and sciatica radiating to one or both lower extremities. Conservative treatment was administered. Neurological examination findings, durations of treatment and intervals until symptomatic recovery were recorded. Laségue tests and neurosensory examination revealed that mild neurological deficits existed in 16 of our patients. Previously, 5 patients had received physiotherapy and 7 patients had been on medical treatment. The number of patients with LDH at the level of L3-L4, L4-L5, and L5-S1 were 1, 13, and 9, respectively. All patients reported that they had benefit from medical treatment and bed rest, and radiologic improvement was observed simultaneously on MRI scans. The average duration until symptomatic recovery and/or regression of LDH symptoms was 13.6 ± 5.4 months (range: 5-22). It should be kept in mind that lumbar disc hernias could regress with medical treatment and rest without surgery, and there should be an awareness that these patients could recover radiologically. This condition must be taken into account during decision making for surgical intervention in LDH patients devoid of indications for emergent surgery.

    Despite numerous biomechanical studies have been carried out on dynamic stabilizers, there is very little information on their hybrid application, especially when combined interspinous dynamic stabilization with single-level fusion. The aim of this study is to assess the biomechanical effect of interspinous dynamic stabilization adjacent to single-level fusion on range of motion of the transition segment and the adjacent segment. Six fresh lumbosacral spines (L2-S1) were tested in the following sequence: 1) intact (Construct A); 2) fusion in L5/S1 and intact in L4/5 (Construct B); 3) fusion in L5/S1 and unstable state in L4/5 (Construct C); 4) fusion in L5/S1 and Coflex in L4/5 (Construct D). Range of motion (at L3/4 and L4/5) was recorded and calculated. Range of motion in L3/4 in the four constructs showed no difference under all motion states. Under flexion/extension, the range of motion of L4/5 in Construct B and Construct C increased, while the range of motion of L4/5 in Construct D decreased compared with Construct A. Compared with Construct D, the range of motion of L4/5 in Constructs B and C showed a significant increase. Under lateral bending and axial rotation, Construct A showed similar range of motion of L3/4 compared with other constructs. Fusion combined with Coflex is able to stabilize the transition segment and restrict flexion and extension in that segment, while having no significant effect on the range of motion of the adjacent segment or the range of motion of the transition segment under lateral bending and axial rotation.

    To examine both anterior and posterior elements of the lumbar spine in patients with low back pain using MRI T2-weighted sequences with Fat Saturation (FS) and contrast enhanced T1-weighted sequences with FS. Two thousand eight hundred and twenty (2820) patients (1628 male, 1192 female, mean age 54) presenting low back pain underwent MRI standard examination (Sagittal T1w TSE and T2w TSE, axial T1 SE) with the addition of sagittal and axial T2w Fat Sat (FS) sequences. Among all the patients, 987 (35%) have been studied adding Contrast Enhanced (CE) T1w FS sequences after administration of contrast medium. Among 987 patients studied with contrast medium, we found: active-inflammatory intervertebral osteochondrosis in 646 (65%) patients; degenerative-inflammatory changes in facet joints (facet joint effusion, synovitis, synovial cysts) in 462 (47%); spondylolysis in 69 (7%); degenerative-inflammatory changes of the flava, interspinous and supraspinous ligaments in 245 (25%); inflammatory changes of posterior perispinal muscles in 84 (8%) patients. In patients with suspected no-disc-related low back pain, the implementation of T2w FS and CE T1w FS sequences to the standard MR protocol could allow a better identification of degenerative-inflammatory changes more likely associated to the pain.

    Although the connective tissues forming the fascial planes of the back have been hypothesized to play a role in the pathogenesis of chronic low back pain (LBP), there have been no previous studies quantitatively evaluating connective tissue structure in this condition. The goal of this study was to perform an ultrasound-based comparison of perimuscular connective tissue structure in the lumbar region in a group of human subjects with chronic or recurrent LBP for more than 12 months, compared with a group of subjects without LBP. In each of 107 human subjects (60 with LBP and 47 without LBP), parasagittal ultrasound images were acquired bilaterally centered on a point 2 cm lateral to the midpoint of the L2-3 interspinous ligament. The outcome measures based on these images were subcutaneous and perimuscular connective tissue thickness and echogenicity measured by ultrasound. There were no significant differences in age, sex, body mass index (BMI) or activity levels between LBP and No-LBP groups. Perimuscular thickness and echogenicity were not correlated with age but were positively correlated with BMI. The LBP group had approximately 25% greater perimuscular thickness and echogenicity compared with the No-LBP group (ANCOVA adjusted for BMI, p<0.01 and p<0.001 respectively). This is the first report of abnormal connective tissue structure in the lumbar region in a group of subjects with chronic or recurrent LBP. This finding was not attributable to differences in age, sex, BMI or activity level between groups. Possible causes include genetic factors, abnormal movement patterns and chronic inflammation.

    Full Text Available This case report details an interesting case of suspected spinal bifida in an obstetric patient who presented for an elective cesarean section. A large scarred/dimpled area, surrounded by significant hair growth in the region of the lumbar spine had been missed in multiple antenatal and preoperative assessments and was recognized on the day of the surgery as the patient was being prepared for spinal anesthesia. The patient was uncertain regarding the pathology of the lesion, and all investigations relating to this had been undertaken in Pakistan where she lived as a child. General anesthesia was undertaken because magnetic resonance imaging had not been performed and tethering of the spinal cord could not be ruled out clinically. The patient suffered from significant blood loss intra and postoperatively, requiring a two unit blood transfusion. She was discharged after 5 days in the hospital. This case highlights the need for thorough examination in all obstetric patients presenting to the preoperative clinic, focusing on the airway, vascular access, and lumbar spine. Patients may not always disclose certain information due to a lack of understanding, embarrassment, forgetfulness, or language barriers. Significant aspects of their care may have been undertaken abroad and access to these notes is often limited. Preoperative detection of the lesion would have allowed further investigation and imaging of the lesion and enabled more comprehensive discussions with the patient regarding anesthetic options and risk.

    Spinal angiolipomas are fairly infrequent benign tumours that are usually located in the epidural space of the thoracic column and represent 0.14% to 1.3% of all spinal tumours. Lumbar angiolipomas are extremely rare, representing only 9.6% of all spinal extradural angiolipomas. We report the case of a woman who complained of a lumbar pain of several months duration with no neurological focality and that had intensified in the last three days without her having had any injury or made a physical effort. The MR revealed an extradural mass L1-L2, on the posterior face of the medulla, decreasing the anteroposterior diameter of the canal. The patient symptoms improved after surgery. Total extirpation of the lesion is possible in most cases, and the prognosis is excellent even if the lesion is infiltrative. For this reason, excessively aggressive surgery is not necessary to obtain complete resection. Copyright © 2016 Sociedad Española de Neurocirugía. Publicado por Elsevier España, S.L.U.

    The aim of this study was to demonstrate the feasibility of MR-guided lumbar sympathicolysis (LSL) in a non-selected patient population. One hundred one MR-guided LSL procedures were performed in 89 patients according to Haaga's technique using a horizontally open clinical MR system (0.2 T) and non-ferromagnetic 20-G cannulas (neurolysis, n=93; blockade, n=8). Only gradient-recalled sequences in either single or multislice mode [fast imaging with steady-state precession (FISP) and fast low-angle shot] were applied for anatomical survey and needle guiding. Bupivacaine injection was monitored with MR fluoroscopically. Fluid distribution was subsequently documented in a CT scan in 65 patients. Ninety-one LSL procedures could be successfully completed. Ten patients were not treated using MR due to patient inconvenience, severe motion artifacts (n=4 each), excessive spondylophytes, and retroperitoneal hematoma (n=1 each). One case of ureteral necrosis occurred. Motion artifacts were rated less severe in single-slice FISP sequences and in obese patients. An average of 3.48 sequence measurements were required for definitive needle placement. Average table time was 32.3 min. An MR-guided LSL is feasible and can be performed with acceptable safety and time effort. It can be recommended for repeated sympathetic blockades in younger patients to avoid cumulative irradiation associated with CT guidance. (orig.)

    The traction bed is a noninvasive device for treating lower back pain caused by herniated intervertebral discs. In this study, we investigated the impact of the traction bed on the lower back as a means of increasing the disc height and creating a gap between facet joints. Computed tomography (CT) images were obtained from a female volunteer and a three-dimensional (3D) model was created using software package MIMICs 17.0. Afterwards, the 3D model was analyzed in an analytical software (Abaqus 6.14). The study was conducted under the following traction loads: 25%, 45%, 55%, and 85% of the whole body weight in different angles. Results indicated that the loading angle in the L3-4 area had 36.8%, 57.4%, 55.32%, 49.8%, and 52.15% effect on the anterior longitudinal ligament, posterior longitudinal ligament, intertransverse ligament, interspinous ligament, and supraspinous ligament, respectively. The respective values for the L4-5 area were 32.3%, 10.6%, 53.4%, 56.58%, and 57.35%. Also, the body weight had 63.2%, 42.6%, 44.68%, 50.2%, and 47.85% effect on the anterior longitudinal ligament, posterior longitudinal ligament, intertransverse ligament, interspinous ligament, and supraspinous ligament, respectively. The respective values for the L4-5 area were 67.7%, 89.4%, 46.6%, 43.42% and 42.65%. The authenticity of results was checked by comparing with the experimental data. The results show that traction beds are highly effective for disc movement and lower back pain relief. Also, an optimal angle for traction can be obtained in a 3D model analysis using CT or magnetic resonance imaging images. The optimal angle would be different for different patients and thus should be determined based on the decreased height of the intervertebral disc, weight and height of patients.

    A randomized single-blind clinical trial of facet injections plus exercise, versus exercise alone, in chronic disabling work-related lumbar spinal disorders (CDWRLSD), accompanied by pilot interrater reliability and facet syndrome prevalence studies. To systematically investigate the use of facet injections as an adjunct to supervised lumbar stretching exercises in regaining lumbar range of motion (ROM) following prolonged deconditioning after work-related lumbar injuries. To assess interrater reliability of visual assessment of segmental rigidity (SR), and to evaluate the prevalence of facet syndrome in cases of lumbar SR. Corticosteroid joint injections have often been used to reduce musculoskeletal inflammation to facilitate joint mobilization in the presence of degenerative arthritis. Lumbar segmental rigidity is a recently described entity usually associated with painful chronic spinal disorders and postoperative spine surgery. Previous work has shown that SR and lumbar ROM improves with a brief intervention consisting of facet injections followed by specific stretching exercises. No systematic study has investigated the potential benefits of a combination of facet injections and exercise over supervised exercises alone to treat lumbar SR. Similarly, no study has assessed the association between SR and the facet syndrome. From a group of consecutive patients (n = 421) with CDWRLSD referred for tertiary rehabilitation between November 1999 and January 2001, 70 were noted to have SR on intake physical examination. The first part of this study assessed interrater reliability for detecting SR, and intrarater reliability for 3-segment true lumbar ROM measurements. Patients randomly assigned to participate in supervised stretching exercises with the addition of fluoroscopically guided bilateral facet injections at the involved levels (Group A, n = 36) also underwent facet syndrome prevalence assessment at the time of injection. They were compared to a randomly

    Lumbar spondylolisthesis is a common finding on plain radiographs. The condition has a variety of causes which can be differentiated on the basis of imaging findings. As the treatment is dependent upon the type of spondylolisthesis, it is important for the radiologist to be aware of these features. We present a pictorial review of the imaging features of lumbar spondylolisthesis and explain the differentiating points between different groups of this disorder. The relative merits of the different imaging techniques in assessing lumbar spondylolisthesis are discussed.

    A prospective, controlled study was performed to compare side effect incidences after lumbar iohexol myelography (n=97) and diagnostic lumbar puncture (n=85). No significant side effect incidence differences (iohexol vs. controls) were found regarding number of patients with any side effect (63 vs. 73%), headache (44 vs. 54%), nausea, dizziness, visual, auditory, or psychic symptoms. Early-onset headache occurred significantly more often in the iohexol group (16 vs 5%), while postural headache occurred most frequently after lumbar puncture (25 vs. 41%). These results suggest that apart from the slight early-onset headache, most side effets after lumbar iohexol myelography are related to the puncture per se, not to the contrast agent. (orig.)

    Vascular complications of lumbar disc surgery are rare. Few cases have been reported. Arteriovenous fistulas are the most common. They are due to anatomical relationships between the last lumbar vertebrae, the corresponding discs, and the iliac vessels; degenerative lesions of the intervertebral discs facilitate instrumental vessel perforation, and operative difficulty. Computed tomography is particularly accurate for making the diagnosis. Treatment strategies consist in surgery or endovascular management. Percutaneous endovascular treatment using a stent-graft is a reasonable option for treating arteriovenous fistula. We describe the case of a 50-year-old patient who developed an iliocaval arteriovenous fistula following lumbar disc hernia surgery. The lesion was excluded by a stent-graft. The postoperative period was uneventful. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    Full Text Available Swinging a golf club includes the rotation and extension of the lumbar spine. Golf-related low back pain has been associated with degeneration of the lumbar facet and intervertebral discs, and with spondylolysis. Reflective markers were placed directly onto the skin of 11young male amateur golfers without a previous history of back pain. Using a VICON system (Oxford Metrics, U.K., full golf swings were monitored without a corset (WOC, with a soft corset (SC, and with a hard corset (HC, with each subject taking 3 swings. Changes in the angle between the pelvis and the thorax (maximum range of motion and angular velocity in 3 dimensions (lumbar rotation, flexion-extension, and lateral tilt were analyzed, as was rotation of the hip joint. Peak changes in lumbar extension and rotation occurred just after impact with the ball. The extension angle of the lumbar spine at finish was significantly lower under SC (38° or HC (28° than under WOC (44° conditions (p < 0.05. The maximum angular velocity after impact was significantly smaller under HC (94°/sec than under SC (177°/sec and WOC (191° /sec conditions, as were the lumbar rotation angles at top and finish. In contrast, right hip rotation angles at top showed a compensatory increase under HC conditions. Wearing a lumbar corset while swinging a golf club can effectively decrease lumbar extension and rotation angles from impact until the end of the swing. These effects were significantly enhanced while wearing an HC

    Radiographic features of consecutive lumbar spondylolisthesis were retrospectively analyzed in a total of 17 patients treated for this condition at the Third Hospital of Hebei Medical University from June 2005 to March 2012.To investigate the radiographic features, pelvic compensatory mechanisms, and possible underlying etiologies of consecutive lumbar spondylolisthesis.To the best of our knowledge, there is no previous report concerning the characteristics of consecutive lumbar spondylolisthesis.The Taillard index and the lumbar lordosis (LL), pelvic incidence (PI), sacrum slope (SS), and pelvic tilt (PT) were determined on lateral X-ray images, and the angular displacement was analyzed on flexion-extension X-ray images. Correlation between LL and various pelvic parameters and correlation between Taillard index and angular displacement were assessed by Pearson correlation analysis.A total of 20 cases of isthmic spondylolisthesis and 14 of degenerative spondylolisthesis were retrospectively studied in 17 patients. The Taillard index and the angular displacement in the lower vertebrae were both larger than those in the upper vertebrae. Statistical analysis revealed that LL was correlated with PI and PT, whereas PI was correlated with PT and SS. However, no correlation was identified between Taillard index and angular displacement.In consecutive lumbar spondylolisthesis, the degree of vertebral slip and the angular displacement of the lower vertebrae were both greater than those of the upper vertebrae, indicating that the compensatory mechanism of the pelvis plays an important role in maintaining sagittal balance.

    Spondylolysis is an osseous defect of the pars interarticularis, thought to be a developmental or acquired stress fracture secondary to chronic low-grade trauma. It is encountered most frequently in adolescents, most commonly involving the lower lumbar spine, with particularly high prevalence among athletes involved in certain sports or activities. Spondylolysis can be asymptomatic or can be a cause of spine instability, back pain, and radiculopathy. The biomechanics and pathophysiology of spondylolysis are complex and debated. Imaging is utilized to detect spondylolysis, distinguish acute and active lesions from chronic inactive non-union, help establish prognosis, guide treatment, and to assess bony healing. Radiography with satisfactory technical quality can often demonstrate a pars defect. Multislice CT with multiplanar reformats is the most accurate modality for detecting the bony defect and may also be used for assessment of osseous healing; however, as with radiographs, it is not sensitive for detection of the early edematous stress response without a fracture line and exposes the patient to ionizing radiation. Magnetic resonance (MR) imaging should be used as the primary investigation for adolescents with back pain and suspected stress reactions of the lumbar pars interarticularis. Several imaging pitfalls render MR imaging less sensitive than CT for directly visualizing the pars defects (regional degenerative changes and sclerosis). Nevertheless, the presence of bone marrow edema on fluid-sensitive images is an important early finding that may suggest stress response without a visible fracture line. Moreover, MR is the imaging modality of choice for identifying associated nerve root compression. Single-photon emission computed tomography (SPECT) use is limited by a high rate of false-positive and false-negative results and by considerable ionizing radiation exposure. In this article, we provide a review of the current concepts regarding spondylolysis, its

    Recent studies have suggested an association between elevated pelvic incidence (PI) and the development of lumbar spondylolysis. However, there is still lack of investigation for Han Chinese people concerning the normal range of spinopelvic parameters and relationship between abnormal sagittal parameters and lumbar diseases. The objective of the study was to investigate sagittal lumbosacral parameters of adult lumbar spondylolysis patients in Han Chinese population. A total of 52 adult patients with symptomatic lumbar spondylolysis treated in the General Hospital of Armed Police Force (Beijing, China) were identified as the spondylolysis group. All the 52 patients were divided into two subgroups, Subgroup A: 36 patients with simple lumbar spondylolysis, and Subgroup B: 16 patients with lumbar spondylolysis accompanying with mild lumbar spondylolisthesis (slip percentage spondylolysis group and the control group with independent-sample t- test. There were no statistically significant differences of all seven sagittal lumbosacral parameters between Subgroup A and Subgroup B. PI, PT, SS, and LL were higher (P spondylolysis group than those in the control group, but STA was lower (P spondylolysis group. Current study results suggest that increased PI and decreased STA may play important roles in the pathology of lumbar spondylolysis in Han Chinese population.

  13. Older literature review of increased risk of adjacent segment degeneration with instrumented lumbar fusions

    2016-01-01

    Background: Adjacent segment degeneration (ASD) following lumbar spine surgery occurs in up to 30% of cases, and descriptions of such changes are not new. Here, we review some of the older literature concerning the rate of ASD, typically more severe cephalad than caudad, and highly correlated with instrumented fusions. Therefore, for degenerative lumbar disease without frank instability, ASD would be markedly reduced by avoiding instrumented fusions. Methods: In a prior review, the newer literature regarding the frequency of ASD following lumbar instrumented fusions (e.g., transforaminal or posterior lumbar interbody fusions [TLIF/PLIF] fusions or occasionally, posterolateral fusions [PLFs]) was presented. Some studies cited an up to an 18.5% incidence of ASD following instrumented versus noninstrumented fusions/decompressions alone (5.6%). A review of the older literature similarly documents a higher rate of ASD following instrumented fusions performed for degenerative lumbar disease alone. Results: More frequent and more severe ASD follows instrumented lumbar fusions performed for degenerative lumbar disease without instability. Alternatively, this entity should be treated with decompressions alone or with noninstrumented fusions, without the addition of instrumentation. Conclusions: Too many studies assume that TLIF, PLIF, and even PLF instrumented fusions are the “gold standard of care” for dealing with degenerative disease of the lumbar spine without documented instability. It is time to correct that assumption, and reassess the older literature along with the new to confirm that decompression alone and noninstrumented fusion avoid significant morbidity and even potentially mortality attributed to unnecessary instrumentation.

    To evaluate the clinical effect of the minimally invasive transforaminal lumbar interbody fusion combined with posterolateral fusion and unilateral fixation using a tubular retractor in the management of degenerative lumbar disease. A retrospective analysis was conducted to analyze the clinical outcome of 58 degenerative lumbar disease patients who were treated with minimally invasive transforaminal lumbar interbody fusion combined with posterolateral fusion and unilateral fixation during December 2012 to January 2015. The spine was unilaterally approached through a 3.0-cm skin incision centered on the disc space, located 2.5 cm lateral to the midline, and the multifidus muscles and longissimus dorsi were stripped off. After transforaminal lumbar interbody fusion and posterolateral fusion the unilateral pedicle screw fixation was performed. The visual analogue scale (VAS) for back and leg pain, the Oswestry disability index (ODI), and the MacNab score were applied to evaluate clinical effects. The operation time, peri-operative bleeding, postoperative time in bed, hospitalization costs, and the change in the intervertebral height were analyzed. Radiological fusion based on the Bridwell grading system was also assessed at the last follow-up. The quality of life of the patients before and after the operation was assessed using the short form-36 scale (SF-36). Fifty-eight operations were successfully performed, and no nerve root injury or dural tear occurred. The average operation time was 138 ± 33 min, intraoperative blood loss was 126 ± 50 mL, the duration from surgery to getting out of bed was 46 ± 8 h, and hospitalization cost was 1.6 ± 0.2 ten thousand yuan. All of the 58 patients were followed up for 7-31 months, with an average of 14.6 months. The postoperative VAS scores and ODI score were significantly improved compared with preoperative data (P degenerative lumbar disease, and the short-term clinical outcome is satisfactory

    Transforaminal endoscopic lumbar discectomy (TELD), a minimally invasive spinal technique, has advantages over open discectomy. Unilateral TELD for disc herniation causing bilateral symptoms is challenging. In this study, we describe a percutaneous endoscopic herniotomy technique by using a unilateral approach for lumbar disc herniation with bilateral obvious symptoms. From June 2014 to October 2015, 26 patients who had back as well as bilateral leg pain and/or weakness due to lumbar disc herniation were treated by TELD with a unilateral approach. Clinical outcomes were evaluated via a visual analogue scale (VAS; 0-10), and functional status was assessed with the Oswestry Disability Index (0-100%) postoperatively and 3 and 12 months postoperatively. Surgical satisfaction rate was assessed during the final follow-up. The mean VAS for leg pain on the operative side improved from preoperative 8.39 ± 1.84 to 2.18 ± 1.26 postoperatively, 1.96 ± 0.83 at 3 months postoperatively, and 2.05 ± 1.42 at 1 year postoperatively (P disc herniation causing bilateral symptoms, through one working channel.

    A retrospective case series. The purpose of this study was to describe a unique group of intercollegiate athletes who are skeletally mature and who developed symptomatic acute lumbar spondylolysis and to study long-term return to play outcome of nonoperative and surgical repair of L3 and L4 spondylolysis in skeletally mature athletes. Traditionally, symptomatic acute lumbar spondylolysis is a defect found in skeletally immature athletes, most commonly in the pars interarticularis of L5, less commonly in the L3/L4 region, and even less commonly in skeletally mature athletes as described in this group. Eight intercollegiate athletes (2 women and 6 men, ages ranging from 19 to 21 y) with acute lumbar spondylolysis were diagnosed by means of computed tomography (CT) and single photon emission-CT bone scan. L3 lesions were present in 5 patients, and L4 lesions were present in 3 patients. All patients were treated initially nonoperatively with a protocol of bracing and activity modification. The healing progress was assessed through repeat CT scan. Patients who failed to respond to nonoperative procedures underwent direct repair of their pars defect through variable angle pedicle screw and sublaminar hook. Outcomes were measured by completion of the Oswestry Low Back Pain Disability Questionnaire (mean follow-up 6.5 y) and return to athletic participation. All patients successfully returned to full athletic competition. Two patients showed radiographic healing and resolution of pain following 3 months of nonoperative treatment. Five patients required surgical repair of the pars defect. All of these patients eventually returned to unrestricted participation in athletics. This study shows that this subgroup will generally respond well to surgical correction of the pars defect and return to uninhibited competition following conservative treatment and/or surgical repair.

    Full Text Available Solitary osteochondromas rarely occur in the axial skeleton. Those tumors mostly arise on the posterior elements of the cervical column causing various symptoms especially when developing within the spinal canal. Exophytic lumbar variety is uncommon presenting with palpable mass or spinal deformity. We report a 20-year-old man presenting with a solid painless mass at the lower lumbar region. Radiological examinations revealed an exophytic lesion arising in the third lumbar spinous process appearing to be a solitary osteochondroma. The lesion was treated by en-bloc resection; histopathological examination confirmed the diagnosis of osteochondroma with no evidence of recurrence at the end of 2-year follow up.

    Spinal stenosis, which has attracted increasing attention in recent years, represents an important group of clinical and radiologic entities. Recognition and ultimate surgical management of the many abnormalities found in this group require precise preoperative delineation of the morbid anatomy. Conventional axial tomography provided the first accurate picture of the sagittal dimension, but it was limited by poor contrast resolution. Computerized tomography and ultrasound have finally provided the means for accurate measurement of midsagittal diameter and surface area. It is now possible to provide a preoperative assessment of bony and soft-tissue canal compression and to guide surgical decompression by objective anatomic measurements. True spinal stenosis of the lumbar vertebral canal is a form of compression produced by the walls of the vertebral canal. It involves the whole of the vertebral canal by exerting compression at two of its opposite surfaces. There are two types of stenosis: (1) transport stenosis, wherein the clinical manifestations are due to impeded flow of fluid, which is dependent on the available cross-sectional area of the canal surface of the stenotic structure, and (2) compressive stenosis, which includes abnormal compression of opposing surfaces only. According to these definitions, indentation on the spinal canal by disc protrusion or localized tumor is not considered true spinal stenoses. In this chapter the authors discuss only those conditions that produce true canal stenosis

    Full Text Available Background: Lumbar disc herniation is a major cause of back pain and sciatica. The surgical management of lumbar disc prolapse has evolved from exploratory laminectomy to percutaneous endoscopic discectomy. Percutaneous endoscopic discectomy is the least invasive procedure for lumbar disc prolapse. The aim of this study was to analyze the clinical outcome, quality of life, neurologic function, and complications. Materials and Methods: One hundred patients with lumbar disc prolapse who were treated with percutaneous endoscopic discectomy from May 2012 to January 2014 were included in this retrospective study. Clinical followup was done at 1 month, 3 months, 6 months, 1 year, and at yearly interval thereafter. The outcome was assessed using modified Macnab′s criteria, visual analog scale, and Oswestry Disability Index. Results: The mean followup period was 2 years (range 18 months - 3 years. Transforaminal approach was used in 84 patients, interlaminar approach in seven patients, and combined approach in nine patients. An excellent outcome was noted in ninety patients, good outcome in six patients, fair result in two patients, and poor result in two patients. Minor complications were seen in three patients, and two patients had recurrent disc prolapse. Mean hospital stay was 1.6 days. Conclusions: Percutaneous endoscopic lumbar discectomy is a safe and effective procedure in lumbar disc prolapse. It has the advantage that it can be performed on a day care basis under local anesthesia with shorter length of hospitalization and early return to work thus improving the quality of life earlier. The low complication rate makes it the future of disc surgery. Transforaminal approach alone is sufficient in majority of cases, although 16% of cases required either percutaneous interlaminar approach or combined approach. The procedure definitely has a learning curve, but it is acceptable with adequate preparations.

    Symptom of herpes zoster is sometimes difficult to distinguish from sciatica induced by spinal diseases, including lumbar disc herniation and spinal canal stenosis. Here we report a case of sciatica mimicking lumbar canal stenosis. A 74-year-old Chinese male patient visited our hospital for left-sided sciatic pain upon standing or walking for 5 min of approximately 1 month's duration. At the first visit to our hospital, there were no skin lesions. A magnetic resonance imaging showed spinal canal stenosis between the 4th and 5th lumbar spine. Thus, we diagnosed the patient with sciatica induced by spinal canal stenosis. We considered decompression surgery for the stenosis of 4th and 5th lumbar spine because conservative therapy failed to relieve the patient's symptom. At that time, the patient complained of a skin rash involving his left foot for several days. A vesicular rash and erythema were observed on the dorsal and plantar surfaces of the great toe and lateral malleolus. The patient was diagnosed with herpes zoster in the left 5th lumbar spinal nerve area based on clinical findings, including the characteristics of the pain and vesicular rash and erythema in the 5th lumbar spinal dermatome. The patient was treated with famciclovir (1,500 mg/day) and non-steroidal anti-inflammatory drugs. After 1 week of medication, the skin rash resolved and pain relief was obtained. In conclusion, spinal surgeons should keep in mind herpes zoster infection as one of the possible differential diagnoses of sciatica, even if there is no typical skin rash.

    Full Text Available Impaired motor and sensory functions have been associated with low back pain (LBP. This includes disturbances in a wide range of sensorimotor control e.g. sensory dysfunctions, impaired postural responses and psychomotor control. However, the physiological mechanisms, clinical relevance and characteristics of these findings in different spinal pathologies require further clarification. The purposes of this study were to investigate postural control, lumbar muscle function, movement perception and associations between these findings in healthy volunteers (n=35, patients with lumbar disc herniation (n=20 and lumbar spinal stenosis (LSS, n=26. Paraspinal muscle responses for sudden upper limb loading and muscle activation during flexion-extension movement and the lumbar endurance test were measured by surface electromyography (EMG. Postural stability was measured on a force platform during two- and one-footed standing. Lumbar movement perception was assessed in a motorised trunk rotation unit in the seated position. In addition, measurements of motor-(MEP and somatosensory evoked potentials (SEP and needle EMG examination of lumbar multifidus muscles were performed in the LSS patients. Clinical and questionnaire data were also recorded. A short latency paraspinal muscle response (~50 ms for sudden upper limb loading was observed. The latency of the response was shortened by expectation (p=0.017. The response latency for unexpected loading was similar in healthy persons and disc herniation patients but the latency was not shortened by expectation in the patients (p = 0.014. Also impaired postural control (p < 0.05 and lumbar movement perception (p = 0.012 were observed in disc herniation patients. The impaired lumbar movement perception (p=0.054 and anticipatory muscle activation (p = 0.043 tended to be restored after successful surgery but postural control had still not recovered after 3 months of follow-up. The majority of LSS patients were unable

    Full Text Available Background: Surgical treatment of adult lumbar spinal disorders is associated with a substantial risk of intraoperative and perioperative complications. There is no clearly defined medical literature on complication in lumbar spine surgery. Purpose of the study is to retrospectively evaluate intraoperative and perioperative complications who underwent various lumbar surgical procedures and to study the possible predisposing role of advanced age in increasing this rate. Materials and Methods: From 2007 to 2011 the number and type of complications were recorded and both univariate, (considering the patients′ age and a multivariate statistical analysis was conducted in order to establish a possible predisposing role. 133 were lumbar disc hernia treated with microdiscetomy, 88 were lumbar stenosis, treated in 36 cases with only decompression, 52 with decompression and instrumentation with a maximum of 2 levels. 26 patients showed a lumbar fracture treated with percutaneous or open screw fixation. 12 showed a scoliotic or kyphotic deformity treated with decompression, fusion and osteotomies with a maximum of 7.3 levels of fusion (range 5-14. 70 were spondylolisthesis treated with 1 or more level of fusion. In 34 cases a fusion till S1 was performed. Results: Of the 338 patients who underwent surgery, 55 showed one or more complications. Type of surgical treatment ( P = 0.004, open surgical approach (open P = 0.001 and operative time ( P = 0.001 increased the relative risk (RR of complication occurrence of 2.3, 3.8 and 5.1 respectively. Major complications are more often seen in complex surgical treatment for severe deformities, in revision surgery and in anterior approaches with an occurrence of 58.3%. Age greater than 65 years, despite an increased RR of perioperative complications (1.5, does not represent a predisposing risk factor to complications ( P = 0.006. Conclusion: Surgical decision-making and exclusion of patients is not justified only

    The objective is to present the surgical experience in the repair of the spondylolysis in lumbar spine. Background: Spodylolysis is an important cause of low back pain in young adults and is responsible for high grade of incapacity. Classically, patients with surgical indications with Spondylolysis have been treated with vertebral arthrodesis arthrodesis, with the following functional lost of the intervened segment and biomechanical overload of the upper contiguous segment. There are not previous reports about repairing of lysis in national literature and international references in this technique are scarce. Materials and methods: Eight patients within 2002-2004 were operated, a direct repairing of the lyses by in situ, fusion and interfragmental osteosynthesis with AO 3.5 mm titanium cortical screws with autogenous bone grafts was achieved. The casuistic was analyzed depending on clinical presentation, consolidation, mobility and vitality of the disc in imaginology studies. Results: During the follow-up a firm fusion in all cases, mobility and vitality preservation of the L5-S1 intervertebral disc was detected. There was neither infection nor neurological deficit. Recommendations: Repairing of spondylolysis in lumbar column, in young symptomatic patients without or with mild lystesis (grade I) and without associated disc damage, is a safe surgical technique

    A retrospective study. The aim of this study is to evaluate, clinically and radiographically, the efficacy of mini-open retroperitoneal anterior lumbar discectomy followed by anterior lumbar interbody fusion (ALIF) for recurrent lumbar disc herniation following primary posterior instrumentation. Recurrent disc herniation following previous disc surgery occurs in 5 to 15% of cases. This is often treated by further surgical intervention where posterior approach is generally preferred. However, posterior surgery may be problematic if the initial surgery involved posterior instrumentation. An anterior approach may be indicated in these patients, and recent findings suggest that a "mini-open" procedure may have some benefits when compared with traditional open techniques and their associated morbidities. A total of 35 recurrent lumbar disc herniation patients (10 male, 25 female) following primary posterior instrumentation with an average age of 52.8 years (range: 34-70 yrs) who underwent the mini-open ALIF procedures between August 2001 and February 2012 were evaluated retrospectively. The ALIF was performed at the levels L4-L5 (n = 14), L5-S1 (n = 15), or both L4-L5 and L5-S1 (n = 6). Visual Analog pain Scale (VAS) and Oswestry Disability Index (ODI) together with radiological results were assessed. The mean operating time, intraoperative estimated blood loss, and hospital stay were 115 minutes, 70 mL, and 6 days, respectively. No blood transfusion was needed. Transient complication was recorded in two patients. Postoperative follow-up was a minimum 24.3 months. VAS score and ODI percentage decreased significantly from 7.9 ± 0.8 and 78.8% ± 12.4% pre-operatively to 1.4 ± 0.6 and 21.7 ± 4.2% at final follow-up, respectively. There was no neurological worsening and radicular pain improved significantly compared with pre-operation in all the patients. Computed tomographic reconstruction 12 and 24 months after surgery showed bony fusion

    Controlled experimental study. To evaluate the kinematical effects of X-Stop device on the spinal process at the operated and the adjacent segments before and after X-Stop surgeries during various weight-bearing postures in elderly patients with lumbar spine stenosis. The mechanism of interspinous process (ISP) devices is to directly distract the ISP of the implanted level to indirectly decompress the intervertebra foramen and spinal canal. Few studies have investigated the changes of ISP gap caused by X-Stop implantation using magnetic resonance imaging or radiography, but the effect of X-Stop surgery on the kinematics of spinous processes during functional activities is still unclear. Eight patients were tested before and, on average, 7 months after surgical implantation of the X-Stop devices using a combined computed tomography/magnetic resonance imaging and dual fluoroscopic imaging system during weight-bearing standing, flexion-extension, left-right bending, and left-right twisting positions of the torso. The shortest distances of the ISPs at the operated and the adjacent levels were measured using iterative closest point method and was dissected into vertical (gap) and horizontal (lateral translation) components. At the operated levels, the shortest vertical ISP distances (gap) significantly (P0.05) in right twist, left bend, and right bend after the X-Stop implantation. The lateral translations were not significantly affected. At both cephalad and caudad adjacent levels, the ISP distances (vertical and horizontal) were not significantly affected during all postures after X-Stop implantation. The findings of this study indicate that implantation of the X-Stop devices can effectively distract the ISP space at the diseased level without causing apparent kinematic changes at the adjacent segments during the studied postures.

    We describe our endoscopic lumbar sympathectomy technique and our early experience using it to treat plantar hyperhidrosis. We reviewed 20 lumbar sympathectomies performed in our vascular unit for plantar hyperhidrosis in 10 patients from 2011 and 2014. Demographics and outcomes were analyzed and a review of the literature conducted. All procedures were carried out endoscopically with no intraoperative or postoperative morbidity. Plantar anhidrosis was achieved in all the patients, although two patients (20%) suffered a relapse. Unwanted side-effects occurred in the form of compensatory sweating in three patients (30%) and post-sympathectomy neuralgia in two patients (20%). None of the patients experienced sexual dysfunction. Management of plantar hyperhidrosis may be based upon a therapeutic ladder starting with conservative measures and working up to surgery depending on the severity of the disease. Minimally invasive (endoscopic) sympathectomy for the thoracic chain is well established, but minimally invasive sympathectomy for the lumbar chain is a relatively new technique. Endoscopic lumbar sympathectomy provides an effective, minimally invasive method of surgical management, but long-term data are lacking. © 2016 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and John Wiley & Sons Australia, Ltd.

As radiologists, we tend to focus on the technical aspects of a procedure and the anatomic/morphologic information it provides. However, it cannot be emphasized enough that when performing lumbar discography, the assessment of the patient's pain response during the injection is the most important component of the procedure, and requires not only technical skills, but an understanding of how best to avoid some of the pitfalls that can lead to inaccurate results.

    The aim of this study is to determine the feasibility and efficacy of surgical management of single-segment lumbar spinal tuberculosis (TB) by using single-stage posterior transforaminal lumbar interbody fusion, debridement, limited decompression, 3-column reconstruction, and posterior instrumentation. Seventeen cases of single-segment lumbar TB were treated with single-stage posterior transforaminal lumbar interbody fusion, debridement, limited decompression, 3-column reconstruction, and posterior instrumentation. The mean follow-up was 36.9 months (range: 24-62 months). The kyphotic angle ranged from 15.2-35.1° preoperatively, with an average measurement of 27.8°. The American Spinal Injury Association (ASIA) score system was used to evaluate the neurological deficits and erythrocyte sedimentation rate (ESR) used to judge the activity of TB. Spinal TB was completely cured in all 17 patients. There was no recurrent TB infection. The postoperative kyphotic angle was 6.6-10.2°, 8.1° in average, and there was no significant loss of the correction at final follow-up. Solid fusion was achieved in all cases. Neurological condition in all patients was improved after surgery. Single-stage posterior transforaminal lumbar interbody fusion, debridement, limited decompression, 3-column reconstruction, and posterior instrumentation can be a feasible and effective method the in treatment of single-segment lumbar spinal TB.

  16. Lumbar degenerative spinal deformity: Surgical options of PLIF, TLIF and MI-TLIF

    Full Text Available Degenerative disease of the lumbar spine is common in ageing populations. It causes disturbing back pain, radicular symptoms and lowers the quality of life. We will focus our discussion on the surgical options of posterior lumbar interbody fusion (PLIF and transforaminal lumbar interbody fusion (TLIF and minimally invasive transforaminal lumbar interbody fusion (MI-TLIF for lumbar degenerative spinal deformities, which include symptomatic spondylolisthesis and degenerative scoliosis. Through a description of each procedure, we hope to illustrate the potential benefits of TLIF over PLIF. In a retrospective study of 53 ALIF/PLIF patients and 111 TLIF patients we found reduced risk of vessel and nerve injury in TLIF patients due to less exposure of these structures, shortened operative time and reduced intra-operative bleeding. These advantages could be translated to shortened hospital stay, faster recovery period and earlier return to work. The disadvantages of TLIF such as incomplete intervertebral disc and vertebral end-plate removal and potential occult injury to exiting nerve root when under experienced hands are rare. Hence TLIF remains the mainstay of treatment in degenerative deformities of the lumbar spine. However, TLIF being a unilateral transforaminal approach, is unable to decompress the opposite nerve root. This may require contralateral laminotomy, which is a fairly simple procedure.The use of minimally invasive transforaminal lumbar interbody fusion (MI-TLIF to treat degenerative lumbar spinal deformity is still in its early stages. Although the initial results appear promising, it remains a difficult operative procedure to master with a steep learning curve.

    Congenital hypoplasia of the spinal pedicle is a rare condition. Previously reported cases were treated conservatively or with posterior instrumented fusion. However, the absence or hypoplasia of the lumbar pedicle may increase the difficulty of pedicle screw fixation and fusion. Herein, the authors describe 2 cases of rare adult congenital hypoplasia of the right lumbar pedicles associated with spondylolisthesis. The patients underwent anterior lumbar interbody fusion with a stand-alone cage as well as percutaneous pedicle screw fixation. This method was used to avoid the difficulties associated with pedicle screw fixation and to attain solid fusion. Both patients achieved satisfactory outcomes after a minimum of 2 years of follow-up. This method may be an alternative for patients with congenital hypoplasia of the lumbar spinal pedicle.

    Full Text Available A 70-year-old outpatient presented with a chief complaint of sudden left leg motor weakness and sensory disturbance. He had undergone L4/5 posterior interbody fusion with L3–5 posterior fusions for spondylolisthesis 3 years prior, and the screws were removed 1 year later. He has been followed up for 3 years, and there had been no adjacent segment problems before this presentation. Lumbar magnetic resonance imaging (MRI showed a large L2/3 disc hernia descending to the L3/4 level. Compared to the initial MRI, this hernia occurred in an “intact” disc among multilevel severely degenerated discs. Right leg paresis and bladder dysfunction appeared a few days after admission. Microscopic lumbar disc herniotomy was performed. The right leg motor weakness improved just after the operation, but the moderate left leg motor weakness and difficulty in urination persisted.

    Described is a new automated lumbar disk aspiration technique in which a 2-mm suction cutting probe is used. The procedure allows rapid and safe removal of disk material percutaneously. The presentation describes the technique and the preliminary results of a cooperative study. The procedure is performed under local anesthesia and the aspiration probe is placed into the disk under fluoroscopic guidance and using a posterrolateral approach. One hundred twenty patients have met the study criteria, undergone the procedure, and had at least a 6-week follow-up. Of these, 74% have achieved good to excellent results, based on physician and patient satisfaction and three other criteria. Of 93 patients for whom 6-mont follow-up is available, 71% have achieved good to excellent results. No complications have been reported. The preliminary results indicate that percutaneous automated diskectomy is a low morbidity procedure that can be done on an outpatient basis and be used successfully to treat uncomplicated herniated lumbar disks

    We report here on an unusual case of multiple levels of asymmetric lumbar spondylolysis in a 19-year-old woman. The patient had severe low back pain of increasing intensity with lumbar instability, which was evident on the dynamic radiographs. MRI demonstrated the presence of abnormalities and the three dimensional CT scan revealed asymmetric complete spondylolysis at the left L2, L3 and L4 levels and the right L1, L2 and L3 levels. This case was treated surgically by posterior and posterolateral fusion at L2-3-4 with intersegmental fixation using pedicle screws and an auto iliac bone graft. The patient was relieved of her low back pain after the surgery. PMID:20404945

    Herniated lumbar disc may be asymptomatic or associated with lower limb radiculopathy. Most spinal surgeons would offer surgery following a period of conservative measures if the radiological and clinical findings correlate. However, the existing dictum that lumbar radiculopathy should correlate with ipsilateral lumbar disc herniation may not be accurate as it can rarely present with contralateral sciatica. Literature regarding this phenomenon is scarce. Therefore, we report a patient with herniated lumbar disc presenting with predominantly contralateral motor weakness radiculopathy, which resolved after discectomy.

    Abstract Although spondylolisthesis was traditionally treated with posterior lumbar interbody fusion (PLIF), minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) was recently proposed as an alternative treatment for spondylolisthesis. However, no studies have focused on the comparison of these 2 techniques’ outcome on spondylolisthesis. The operative reports and perioperative data of patients who underwent single-level primary open PLIF (n = 29) and MIS-TLIF (n = 26) for I/II spondylolisthesis were retrospectively evaluated. Patients’ demographics, operative blood loss, hospital length of stay, creatine kinase (CK) level, radiographic fusion, complications, and patient-reported outcomes were evaluated. Radiographic fusion was assessed using the Bridwell grading criteria. Preoperative and postoperative patient-reported outcomes included the visual analog scale (VAS) and Oswestry Disability Index (ODI). Average follow-up was 28 ± 3.6 months (range 24–32 months). Bed rest time, hospital stay, estimated blood loss, and operative time in the MIS-TLIF group were significantly lower than those in the PLIF group (P  .05). Compared with PLIF, MIS-TLIF for grade I/II spondylolisthesis can achieve similar reduction and fusion results with better short-term quality of life, shorter hospital stays, less estimated blood loss, and shorter operative times.

    Intraradicular lumbar disc herniation is a rare complication of disc disease that is generally diagnosed only during surgery. The mechanism for herniated disc penetration into the intradural space is not known with certainty, but adhesion between the radicular dura and the posterior longitudinal ligament was suggested as the most important condition. The authors report the first case of an intraradicular lumbar disc herniation without subdural penetration; the disc hernia was lodged between the two radicular dura layers. The patient, a 34-year-old soldier, was admitted with a 12-month history of low back pain and episodic left sciatica. Neurologic examination showed a positive straight leg raising test on the left side without sensory, motor or sphincter disturbances. Spinal CT scan and MRI exploration revealed a left posterolateral osteophyte formation at the L5–S1 level with an irregular large disc herniation, which migrated superiorly. An intradural extension was suspected. A left L5 hemilaminectomy and S1 foraminotomy were performed. The exploration revealed a large fragment of disc material located between the inner and outer layers of the left S1 radicular dura. The mass was extirpated without cerebrospinal fluid outflow. The postoperative course was uneventful. Radicular interdural lumbar disc herniation should be suspected when a swollen, hard and immobile nerve root is present intraoperatively. PMID:19888608

    Full Text Available Background : Lumbar disc herniation often causes sciatica. Many different techniques have been advocated with the aim of least possible damage to other structures while dealing with prolapsed disc surgically in the properly selected and indicated cases. Methods : Twenty six patients with clinical symptoms and signs of prolapsed lumbar intervertebral disc having radiological correlation by MRI study were subjected to disc excision by interlaminar fenestration method. Results : The assessment at follow-up showed excellent results in 17 patients, good in 6 patients, fair in 2 patients and poor in 1 patient. The mean preoperative and postoperative Visual Analogue Scores were 9.34 ±0.84 and 2.19 ±0.84 on scale of 0-10 respectively. These were statistically significant (p value< 0.001, paired t test. No significant complications were recorded. Conclusion : Procedures of interlaminar fenestration and open disc excision under direct vision offers sufficient adequate exposure for lumbar disc excision with a smaller incision, lesser morbidity, shorter convalescence, early return to work and comparable overall results in the centers where recent laser and endoscopy facilities are not available.

    Full Text Available Background: Avulsion or fracture of posterior ring apophysis of lumbar vertebra is not a common clinical entity and is missed often. These fractures are mostly traumatic lesions typically seen in adolescents and young adults, because fusion in this area is not complete until the age of 18 to 25 years. These fractures are occult on plain radiographs and are frequently missed due to unfamiliarity with the entity. But, CT scanning and MR imaging shows characteristic picture. Methods: We had 21 cases of fracture of posterior margin of a lumbar vertebral body from 1991 to 2002. Fracture in all patients were classified according to CT imaging, into the three types described by Takata et al. Out of these, 8 patients were of type I, 4 patients of type II and 9 patients of type III respectively. Focal deficit / muscle weakness was present in only three patients. No fractures of type IV (Epstein et al was found. Twelve patients were treated conservatively and 9 patients were treated by posterior decompression with total laminectomy and removal of retropulsed fragment and discectomy. Results: The mean follow-up period was of 42 months. Conventional radiography could locate the fracture in only 6 cases and CT scan was required in all cases for stamping the diagnosis and classification. Though it is uncommon, high index of suspicion is required to diagnose it, in especially adolescent patients. All the 21 patients had good outcome following the management. Conclusion: Avulsion or fracture of posterior margin of lumbar vertebral body is not so rare entity. In children and young adults diagnosed as having lumbar disc herniation, this lesion may be the proper diagnosis. These fractures need to be accurately diagnosed because as compared to simple disc herniations these fractures require more extensive exposure and resection to relieve the nerve impingent.

    Three-column lumbar spinal resection osteotomies including pedicle subtraction osteotomy (PSO), vertebral column resection (VCR), and total en bloc spondylectomy (TES) can potentially lead to dorsal root ganglion (DRG) injury which may cause postoperative dysesthesia (POD). The purpose of retrospective study was to describe the uncommon complication of POD in lumbar spinal resection osteotomies. Between January 2009 and December 2013, 64 patients were treated with lumbar three-column spinal resection osteotomies (PSO, n = 31; VCR, n = 29; TES, n = 4) in investigator group. POD was defined as dysesthetic pain or burning dysesthesia at a proper DRG innervated region, whether spontaneous or evoked. Non-steroidal antiinflammatory drugs, central none-opioid analgesic agent, neuropathic pain drugs and/or intervertebral foramen block were selectively used to treat POD. There were 5 cases of POD (5/64, 7.8 %), which consisted of 1 patient in PSO (1/31, 3.2 %), 3 patients in PVCR (3/29, 10.3 %), and 1 patient in TES (1/4, 25 %). After the treatment by drugs administration plus DRG block, all patients presented pain relief with duration from 8 to 38 days. A gradual pain moving to distal end of a proper DRG innervated region was found as the beginning of end. Although POD is a unique and rare complication and maybe misdiagnosed as nerve root injury in lumbar spinal resection osteotomies, combination drug therapy and DRG block have an effective result of pain relief. The appearance of a gradual pain moving to distal end of a proper DRG innervated region during recovering may be used as a sign for the good prognosis.

    Lumbar muscle fatigue is a potential risk factor for the development of low back pain. In this study, we investigated the influence of lumbar extensor muscle fatigue on lumbar-pelvic coordination patterns during weightlifting. Each of the 15 male subjects performed five repetitions of weightlifting tasks both before and after a lumbar extensor muscle fatiguing protocol. Lumbar muscle electromyography was collected to assess fatigue. Trunk kinematics was recorded to calculate lumbar-pelvic continuous relative phase (CRP) and CRP variability. Results showed that fatigue significantly reduced the average lumbar-pelvic CRP value (from 0.33 to 0.29 rad) during weightlifting. The average CRP variability reduced from 0.17 to 0.15 rad, yet this change ws statistically not significant. Further analyses also discovered elevated spinal loading during weightlifting after the development of lumbar extensor muscle fatigue. Our results suggest that frequently experienced lumbar extensor muscle fatigue should be avoided in an occupational environment. Lumbar extensor muscle fatigue generates more in-phase lumbar-pelvic coordination patterns and elevated spinal loading during lifting. Such increase in spinal loading may indicate higher risk of back injury. Our results suggest that frequently experienced lumbar muscle fatigue should be avoided to reduce the risk of LBP.

    Full Text Available Abstract Background Exposure of the anterior or lateral lumbar via the retroperitoneal approach easily causes injuries to the lumbar plexus. Lumbar plexus injuries which occur during anterior or transpsoas lumbar spine exposure and placement of instruments have been reported. This study aims is to provide more anatomical data and surgical landmarks in operations concerning the lumbar plexus in order to prevent lumbar plexus injuries and to increase the possibility of safety in anterior approach lumbar surgery. Methods To study the applied anatomy related to the lumbar plexus of fifteen formaldehyde-preserved cadavers, Five sets of Virtual Human (VH data set were prepared and used in the study. Three-dimensional (3D computerized reconstructions of the lumbar plexus and their adjacent structures were conducted from the VH female data set. Results The order of lumbar nerves is regular. From the anterior view, lumbar plexus nerves are arranged from medial at L5 to lateral at L2. From the lateral view, lumbar nerves are arranged from ventral at L2 to dorsal at L5. The angle of each nerve root exiting outward to the corresponding intervertebral foramen increases from L1 to L5. The lumbar plexus nerves are observed to be in close contact with transverse processes (TP. All parts of the lumbar plexus were located by sectional anatomy in the dorsal third of the psoas muscle. Thus, access to the psoas major muscle at the ventral 2/3 region can safely prevent nerve injuries. 3D reconstruction of the lumbar plexus based on VCH data can clearly show the relationships between the lumbar plexus and the blood vessels, vertebral body, kidney, and psoas muscle. Conclusion The psoas muscle can be considered as a surgical landmark since incision at the ventral 2/3 of the region can prevent lumbar plexus injuries for procedures requiring exposure of the lateral anterior of the lumbar. The transverse process can be considered as a landmark and reference in surgical

    flexion, obesity or quite simply overuse, involve an increase in the lumbar lordosis. The posterior articulations are worn out and the disc gets damaged by shear forces. The disc space becomes shorter with a bulging disc, and the inferior articular process of the superior vertebra goes down. This is responsible of a loss of lordosis. For restoring the sagittal balance the patient needs more extension of the spine. Above and below the considered level the degenerative disease carries on extending to the whole spine. At the level considered, because of local extension, the inferior facet moves forward, the disc bulges, the ligamentum flavum is shortened and the stenosis is increased. This situation is improved by local kyphosis: the inferior facet moves backward, the disc and the ligamentum flavum are stretched with a quite normal posterior disc height and most often there is no more stenosis. Myelograms show this very well with a quite normal appearance lying, clear compression standing, worse in extension and improved, indeed disappeared in flexion. CT scan and MRI don't show that because they are done lying. The expression of the clinical situation is the same, mute lying and maximum standing with restriction of walking. For us lumbar stenosis is operated with lumbar reconstruction without opening the canal. The patient is in moderate kyphosis on the operating table. Pedicle screws rotated to match a bent rod allow reduction of the spine. The posterior disc height is respected and not distracted, and the anterior part of the disc is stretched in lordosis. The inferior facet is cut for the arthrodesis and no longer compresses the dura. The canal is well enlarged and the lumbar segment in lordosis is the best protection of the adjacent levels at follow-up. This behaviour responds to the same analysis as the ≪recalibrage≫ (enlargement). The mobile segment is damaged by the degenerative disease, the stenosis is a consequence of this damage. It's logical to treat the

    A case report and clinical discussion. To describe a rare but fatal complication secondary to oxygen-ozone therapy for the treatment of herniated lumbar disc. Previously reported complications secondary to oxygen-ozone therapy are rarely reported. Septic discitis and epidural abscesses have been reported after myelography, lumbar puncture, paravertebral injections, epidural anesthesia, acupuncture, and intradiscal therapy with chymopapain. We report the first case of a local infection with systemic fatal dissemination secondary to this treatment. A 57-year-old man previously treated with oxygen-ozone therapy presented low back and bilateral pain. The lumbar computed tomography revealed the presence of L4-L5 and L5-S1 herniated discs. Three days after admission in the hospital, the patient developed a fulminant septicemia. An abdominal-pelvic and chest computed tomography and blood culture led to the diagnosis of pyogenic lumbar muscle involvement, accompanied with septic pulmonary embolism secondary to Escherichia coli infection. This case report identifies a rare and fatal complication of oxygen-ozone therapy in the treatment of a herniated lumbar disc. Acute fatal septicemia should be considered among the major complications of the oxygen-ozone therapy in the treatment of a herniated lumbar disc.

    Full Text Available Incidental durotomy is a common complication of lumbar spine operations for degenerative disorders. Its incidence varies depending on several risk factors and regarding the intra and postoperative management, there is no consensus. Our objective was to report our experience with incidental durotomy in patients who were operated on for lumbar disc herniation, lumbar spinal stenosis and revision surgeries. Between 2009 and 2012, 1259 patients were operated on for degenerative lumbar disorders. For primary operations, the surgical approach was mino-open, interlamar, uni- or bilateral, as for recurrences, the removal of the compressive element was intended: the epidural scar and the disc fragment. 863 patients (67,7% were operated on for lumbar disc herniation, 344 patients (27,3% were operated on for lumbar spinal stenosis and 52 patients (5% were operated for recurrences. The operations were performed by neurosurgeons with the same professional degree but with different operative volume. Unintentional durotomy occurred in 20 (2,3% of the patients with herniated disc, in 14 (4,07% of the patients with lumbar spinal stenosis and in 12 (23% of the patients who were operated on for recurrences. The most frequent risk factors were: obesity, revised surgery and the physician’s low operative volume. Intraoperative dural fissures were repaired through suture (8 cases, by applying muscle, fat graft or by applying curaspon, tachosil. There existed 4 CSF fistulas which were repaired at reoperation. Incidental dural fissures during operations for degenerative lumbar disorders must be recognized and immediately repaired to prevent complications such as CSF fistula, osteodiscitis and increased medical costs. Preventing, identifying and treating unintentional durotomies can be best achieved by respecting a neat surgical technique and a standardized treatment protocol.

    Full Text Available The “topping-off” technique is a new concept applying dynamic or less rigid fixation such as hybrid stabilization device (HSD or interspinous process device (IPD for the purpose of avoiding adjacent segment disease (ASD proximal to the fusion construct. A systematic review of the literature was performed on the effect of topping-off techniques to prevent or decrease the occurrence of ASD after lumbar fusion surgery. We searched through major online databases, PubMed and MEDLINE, using key words related to “topping-off” technique. We reviewed the surgical results of “topping-off” techniques with either HSD or IPD, including the incidence of ASD at two proximal adjacent levels (index and supra-adjacent level as compared to the fusion alone group. The results showed that the fusion alone group had statistically higher incidence of radiographic (52.6% and symptomatic (11.6% ASD at the index level as well as higher incidence (8.1% of revision surgery. Besides, the HSD (10.5% and fusion groups (24.7% had statistically higher incidences of radiographic ASD at supra-adjacent level than the IPD (1%. The findings suggest that the “topping-off” technique may potentially decrease the occurrence of ASD at the proximal motion segments. However, higher quality prospective randomized trials are required prior to wide clinical application.

    A case of recurrent giant cell reparative granuloma (GCRG) of the lumbar spine successfully treated with denosumab is reported; a fully human monoclonal antibody against the receptor activator of nuclear factor kappa B (RANK) ligand (RANKL). To report the first case of recurrent GCRG of the lumbar spine treated with denosumab. GCRG is a non-neoplastic osteofibrous lesion usually found in the maxilla and mandible but rarely in the spine. It is clinically distinct from giant cell tumor of bone (GCTB), although common histological characteristics such as the proliferation of spindle-shaped stromal cells and multinucleated giant cells are shared. Denosumab has recently been reported to be effective for unresectable GCTB; however, there is only one report of its effect on GCRG. Moreover, the effect of denosumab on GCRG of the spine is unknown. The clinical course, radiological features, pathology, and treatment outcome of a patient with recurrent GCRG of the lumbar spine treated with denosumab are documented. Denosumab treatment was used for this patient with unresectable recurrent GCRG of the lumbar spine. Follow-up lumbar radiography showed significant bone formations in the tumor lesion after 3 months of treatment. On follow-up computerized tomography scans of the L2 and L3 vertebral lesions, the replacement of osoteolytic lesions by the formation of cortical-like bone tissue was clearly identified. We report the first case of recurrent GCRG of the spine successfully treated with denosumab. Treatment with denosumab induced significant bone formation in the unresectable lumbar lesion with stable clinical improvement during the 12-month follow-up period without apparent complications. Denosumab shows promise as a new alternative treatment option for osteoclastic giant cell-rich tumors, such as GCRG, especially for unresectable lesions of the spine. 4.

    Full Text Available Posterior lumbar interbody fusion using cages, titanium rods, and pedicle screws is considered today as the gold standard of surgical treatment of lumbar degenerative disease and has produced satisfying long-term fusion rates. However this rigid material could change the physiological distribution of load at the instrumental and adjacent segments, a main cause of implant failure and adjacent segment disease, responsible for a high rate of further surgery in the following years. More recently, semirigid instrumentation systems using rods made of polyetheretherketone (PEEK have been introduced. This clinical study of 21 patients focuses on the clinical and radiological outcomes of patients with lumbar degenerative disease treated with Initial VEOS PEEK®-Optima system (Innov’Spine, France composed of rods made from PEEK-OPTIMA® polymer (Invibio Biomaterial Solutions, UK without arthrodesis. With an average follow-up of 2 years and half, the chances of reoperation were significantly reduced (4.8%, quality of life was improved (ODI = 16%, and the adjacent disc was preserved in more than 70% of cases. Based on these results, combined with the biomechanical and clinical data already published, PEEK rods systems can be considered as a safe and effective alternative solution to rigid ones.

    Full Text Available Abstract Background Lumbar spinal stenosis is the most frequent reason for spinal surgery in elderly people. For patients with moderate or severe symptoms different conservative and surgical treatment modalities are recommended, but knowledge about the effectiveness, in particular of the conservative treatments, is scarce. There is some evidence that surgery improves outcome in about two thirds of the patients. The aims of this study are to derive and validate a prognostic prediction aid to estimate the probability of clinically relevant improvement after surgery and to gain more knowledge about the future course of patients treated by conservative treatment modalities. Methods/Design This is a prospective, multi-centre cohort study within four hospitals of Zurich, Switzerland. We will enroll patients with neurogenic claudication and lumbar spinal stenosis verified by Computer Tomography or Magnetic Resonance Imaging. Participating in the study will have no influence on treatment modality. Clinical data, including relevant prognostic data, will be collected at baseline and the Swiss Spinal Stenosis Questionnaire will be used to quantify severity of symptoms, physical function characteristics, and patient's satisfaction after treatment (primary outcome. Data on outcome will be collected 6 weeks, and 6, 12, 24 and 36 months after inclusion in the study. Applying multivariable statistical methods, a prediction rule to estimate the course after surgery will be derived. Discussion The ultimate goal of the study is to facilitate optimal, knowledge based and individualized treatment recommendations for patients with symptomatic lumbar spinal stenosis.

    Background: Postoperative remote cerebellar hemorrhage (RCH) as a complication of lumbar spinal surgery is an increasingly recognized clinical entity. The aim of this study was to determine the incidence of RCH after lumbar spinal surgery and to describe diagnostic imaging findings of RCH. Methods: Between October 1996 and March 2007, 2444 patients who had undergone lumbar spinal surgery were included in the study. Thirty-seven of 2444 patients were scanned by CT or MRI due to neurologic symptoms within the first 7 days of postoperative period. The data of all the patients were studied with regard to the following variables: incidence of RCH after lumbar spinal surgery, gender and age, coagulation parameters, history of previous arterial hypertension, and position of lumbar spinal surgery. Results: The retrospective study led to the identification of two patients who had RCH after lumbar spinal surgery. Of 37 patients who had neurologic symptoms, 29 patients were women and 8 patients were men. CT and MRI showed subarachnoid hemorrhage in the folia of bilateral cerebellar hemispheres in both patients with RCH. The incidence of RCH was 0.08% among patients who underwent lumbar spinal surgery. Conclusion: RCH is a rare complication of lumbar spinal surgery, self-limiting phenomenon that should not be mistaken for more ominous pathologic findings such as hemorrhagic infarction. This type of bleeding is thought to occur secondary to venous infarction, but the exact pathogenetic mechanism is unknown. CT or MRI allowed immediate diagnosis of this complication and guided conservative management.

    Spontaneous regression of herniated lumbar discs was reported occasionally. The mechanisms proposed for regression of disc herniation are still incomplete. This paper describes and discusses a case of spontaneous regression of herniated lumbar discs with a new disc protrusion in the adjacent level. A 41-year-old man was admitted with radiating pain and numbness in the left lower extremity with a left posterolateral disc extrusion at L5-S1 level. He was admitted to hospital with low back pain due to disc herniation caudally immigrating at L4-5 level three years ago. He refused the surgical intervention that was offered and was treated conservatively at that time. He had no neurological deficit and a history of spontaneous regression of the extruded lumbar disc; so, a conservative therapy, including bed rest, physical therapy, nonsteroidal anti-inflammatory drugs, and analgesics, was advised. In conclusion, herniated lumbar disc fragments may regress spontaneously. Reports are prone to advise conservative treatment for extruded or sequestrated lumbar disc herniations. However, these patients should be followed up closely; new herniation at adjacent/different level may occur. Furthermore, it is important to know which herniated disk should be removed and which should be treated conservatively, because disc herniation may cause serious complications as muscle weakness and cauda equine syndrome.

    Full Text Available Aggressive open lumbar discectomy is the most commonly performed surgical procedure for patients with persistent low back and leg pain. In this retrospective study,  1,380 patients were evaluated for long-term results of aggressive discectomy for the single level lumbar disk herniation. Demographic data, surgical data, complications and reherniation rate were collected and clinical outcomes were assessed using visual analogue score (VAS, Oswestry disability index (ODI and modified Mcnab criteria. The mean follow-up period was 28.8 months. According to the modified Mcnab criteria, the long-term results were excellent in 640 cases, good in 445 cases, fair in 255 cases, and poor in 40 cases. The mean VAS scores for back and radicular pains and ODI at the end of 2 years were 1.1 ± 1.0, 1.5 ± 0.5 and 6.6 ± 3.1% respectively. The complications were foot drop (n=7, dural tear (n=14, superficial wound infection (n=17, discitis (n=37 and reherniation (n=64. The dural tear and superficial wound infections resolved after treatment but 28 discitis patients were treated by conservatively and the remaining 9 underwent surgery. Among reherniation patients, 58 underwent revision discectomy and 4 underwent transforaminal lumbar interbody fusion and stabilization. Aggressive discectomy is an effective treatment of lumbar disk herniation and maintains a lower incidence of reherniation but leads to a collapse of disc height and in long run gives rise to intervertebral instability and accelerates spondylosis.

    The purpose of this study is to describe the detailed surgical technique and short-term clinical and radiological outcomes of lateral lumbar interbody fusion (LLIF) and in situ lateral screw fixation using a conventional minimally invasive screw fixation system (MISF) for revision surgery to treat rostral lumbar adjacent segment disease. The medical and radiological records were retrospectively reviewed. The surgery was indicated in 10 consecutive patients with rostral adjacent segment stenosis and instability. After the insertion of the interbody cage, lateral screws were inserted into the cranial and caudal vertebra using the MISF through the same LLIF trajectory. The radiological and clinical outcomes were assessed preoperatively and at 1, 3, 6, and 12 months postoperatively. The median follow-up period was 13 months (range, 3-48 months). Transient sensory changes in the left anterior thigh occurred in 3 patients, and 1 patient experienced subjective weakness; however, these symptoms normalized within 1 week. Back and leg pain were significantly improved ( p fusion was confirmed in 7 patients. Subsidence and mechanical failure did not occur in any patients. This study demonstrates that LLIF and in situ lateral screw fixation may be an alternative surgical option for rostral lumbar adjacent segment disease.

    Low back pain is a major cause of disability and requires the development of new devices to treat pathologies and improve prognosis following surgery. Understanding the effects of new devices on the biomechanics of the spine is crucial in the development of new effective and functional devices. The aim of this study was to develop a preliminary parametric, scalable and anatomically accurate finite-element model of the lumbar spine allowing for the evaluation of the performance of spinal devices. The principal anatomical surfaces of the lumbar spine were first identified, and then accurately fitted from a previous model supplied by S14 Implants (Bordeaux, France). Finally, the reconstructed model was defined according to 17 parameters which are used to scale the model according to patient dimensions. The developed model, available as a toolbox named the lumbar model generator, enables generating a population of models using subject-specific dimensions obtained from data scans or averaged dimensions evaluated from the correlation analysis. This toolbox allows patient-specific assessment, taking into account individual morphological variation. The models have applications in the design process of new devices, evaluating the biomechanics of the spine and helping clinicians when deciding on treatment strategies. © 2018 The Author(s).

    Supra/interspinous ligaments connect adjacent spinous processes and act as a stabilizer of the spine. As with other spinal ligaments, it can become ossified. However, few report have discussed ossification supra/interspinous ligaments (OSIL), so its epidemiology remains unknown. We therefore aimed to investigate the prevalence and distribution of OSIL in symptomatic patients with cervical ossification of the posterior longitudinal ligament (OPLL). The participants of our study were symptomatic patients with cervical OPLL who were diagnosed by standard radiographs of the cervical spine. The whole spine CT data as well as clinical parameters such as age and sex were obtained from 20 institutions belong to the Japanese Multicenter Research Organization for Ossification of the Spinal Ligament (JOSL). The prevalence and distribution of OSIL and the association between OSIL and clinical parameters were reviewed. The sum of the levels involved by OPLL (OP-index) and OSIL (OSI-index) as well as the prevalence of ossification of the nuchal ligament (ONL) were also investigated. A total of 234 patients with a mean age of 65 years was recruited. The CT-based evidence of OSIL was noted in 68 (54 males and 14 females) patients (29%). The distribution of OSIL showed a significant thoracic preponderance. In OSIL-positive patients, single-level involvement was noted in 19 cases (28%), whereas 49 cases (72%) presented multi-level involvement. We found a significant positive correlation between the OP-index grade and OSI-index. ONL was noted at a significantly higher rate in OSIL-positive patients compared to negative patients. The prevalence of OSIL in symptomatic patients with cervical OPLL was 29%. The distribution of OSIL showed a significant thoracic preponderance.

    A retrospective study. To determine the incidence and risk factors of adjacent segment disease (ASD) requiring surgery among patients previously treated with spinal fusion for degenerative lumbar disease and to compare the survivorship of adjacent segment according to various risk factors including comparison of fusion methods: posterior lumbar interbody fusion (PLIF) versus posterolateral fusion (PLF). One of the major issues after lumbar spinal fusion is the development of adjacent segment disease. Biomechanically, PLIF has been reported to be more rigid than PLF, and therefore, patients who undergo PLIF are suspected to experience a higher incidence of ASD than those who underwent PLF. There have been many studies analyzing the risk factors of ASD, but we are not aware of any study comparing PLIF with PLF in incidence of ASD requiring surgery. A consecutive series of 490 patients who had undergone lumbar spinal fusion of 3 or fewer segments to treat degenerative lumbar disease was identified. The mean age at index operation was 53 years, and the mean follow-up period was 51 months (12-236 mo). The number of patients treated by PLF and PLIF were 103 and 387, respectively. The incidence and prevalence of revision surgery for ASD were calculated by Kaplan-Meier method. For risk factor analysis, we used log-rank test and Cox regression analysis with fusion methods, sex, age, number of fused segments, and presence of laminectomy adjacent to index fusion. After index spinal fusion, 23 patients (4.7%) had undergone additional surgery for ASD. Kaplan-Meier analysis predicted a disease-free survival rate of adjacent segments in 94.2% of patients at 5 years and 89.6% at 10 years after the index operation. In the analysis of risk factors, PLIF was associated with 3.4 times higher incidence of ASD requiring surgery than PLF (P = 0.037). Patients older than 60 years at the time of index operation were 2.5 times more likely to undergo revision operation than those younger

    Management of degenerative lumbosacral spondylolisthesis with spinal stenosis is still controversial. Surgery is widely used, as well as non-surgical treatment. To evaluate the clinical results and functional outcome after operative treatment in Grade II and III lumbar spine spondylolisthesis. Twelve patients with symptoms and image-confirmed degenerative spondylolisthesis entered the study. Mean patient age was 57 years. Spondylolisthesis Grade II or III, segment L4-L5 or L5-S1 were evaluated. All patients underwent similar protocols. Operative treatment was decompressive laminectomy, posterior one segment fixation, and fusion with autologous bone grafting. Functional outcome measures were Visual Analog Scale (VAS, 10-point scale) and Oswestry Disability Index (ODI, 100-percent scale) after 6 and 12 months. Patient follow-up was 12 months. Preoperatively, 7 patients had severe disability according to ODI, 4 had moderate disability. VAS measured 6 and 7 points in 6 patients, lowest score of 4 points and the highest score of 9. After 6 months, ODI showed 5 patients had minimal and 7 had moderate disability; 2 patients had 0 points on the VAS, 2 had a score of 1, 4 had a score of 2, highest score of 4 points. Treatment outcome effects after 1 year were 9 patients with minimal disability, 3 with moderate; VAS - 2 patients with O points, 3 with 1 point, 4 with 2 points. Patients with degenerative spondylolisthesis and spinal stenosis treated surgically showed substantially greater improvement in pain and functional outcome during a period of 1 year.

    Full Text Available Lumbar spinal stenosis is a common condition in elderly patients and may lead to progressive back and leg pain, muscular weakness, sensory disturbance, and/or problems with ambulation. Multiple studies suggest that surgical decompression is an effective therapy for patients with symptomatic lumbar stenosis. Although traditional lumbar decompression is a time-honored procedure, minimally invasive procedures are now available which can achieve the goals of decompression with less bleeding, smaller incisions, and quicker patient recovery. This paper will review the technique of performing ipsilateral and bilateral decompressions using a tubular retractor system and microscope.

    Spondylodiscitis leads to debility, and few data exist on Candida spondylodiscitis in patients with intravenous drug use. We present a case of Candida albicans lumbar spondylodiscitis in a patient with intravenous drug use. This patient was treated with surgical debridement and 9 months of fluconazole therapy, and the neurological deficits resolved completely. The infection did not recur clinically or radiologically during 9 months of follow-up. Although Candida albicans lumbar spondylodiscitis is rare, Candida should be suspected as a causative pathogen in patients with intravenous drug use except for Staphylococcus aureus, Pseudomonas aeruginosa, and Mycobacterium tuberculosis. As soon as Candida albicans lumbar spondylodiscitis is suspected, magnetic resonance imaging and percutaneous biopsy should be performed. Surgical intervention combined with treatment with antifungal medications can successfully eradicate the infection and resolve the neurological deficits.

    Solitary osteochondromas rarely occur in the axial skeleton. Those tumors mostly arise on the posterior elements of the cervical column causing various symptoms especially when developing within the spinal canal. Exophytic lumbar variety is uncommon presenting with palpable mass or spinal deformity. We report a 20-year-old man presenting with a solid painless mass at the lower lumbar region. Radiological examinations revealed an exophytic lesion arising in the third lumbar spinous process appearing to be a solitary osteochondroma. The lesion was treated by en-bloc resection; histopathological examination confirmed the diagnosis of osteochondroma with no evidence of recurrence at the end of 2-year follow up.

    Full Text Available Introduction: Vasculopathy, such as an aneurysm, stenosis, rupture, or arteriovenous fistula, in patients with neurofibromatosis type I (NF-1; von Recklinghausen disease is well recognised. However, there has been no report regarding treatment for a ruptured lumbar artery aneurysm associated with NF-1. We present the first report of successful endovascular treatment by coil embolisation for a ruptured lumbar artery aneurysm in a patient with NF-I. Report: A 52 year old man with a history of NF-1 was referred with back pain and anaemia. The computed tomography scan showed rupture of a solitary lumbar artery aneurysm. The rupture was successfully treated by endovascular embolisation with a coil and N-butyl-2-cyanoacrylate. Discussion: Endovascular treatment with coil embolisation was performed safely in this patient. Keywords: Aneurysm, Arteries, Neurofibromatosis 1, Rupture, Case reports

    2007-02-01

    The present study was conducted to establish reasonable indications of patient neurological manifestations for use of percutaneous laser disc decompression (PLDD). PLDD is a less invasive surgical procedure for lumbar disc hernia, whose indications have been described on the basis of radiographical findings. Sixty-five consecutive patients (45 men and 20 women) with lumbar disc hernia were treated with PLDD by applying a diode laser (wavelength 805 nm). A total of 450-1,205 joules (average, 805.5 joules) were delivered per disc. All patients suffered from radicular pain. They were divided based on the presence of Lasegue's sign. The post-procedure results at 1 week and 1 year were compared between the groups. PLDD was effective for patients with Lasegue's sign (80.0%), but ineffective for those without the sign. The present study suggests that Lasegue's sign in patients is an indication of PLDD for lumbar disc hernia.

    The subject of the study was an assessment of the usefulness of radiculography and resonance tomography in the diagnosis of lumbar discopathy. The study was carried out in 100 cases of lumbar discopathy treated at the Department of Spondyloneurosurgery Institute of Rheumatology in Warsaw. Both radiculography and resonance tomography were found to be of equal diagnostic value in the verification of the clinical symptoms of this discopathy. The detection rate of lumbar discopathy by both methods was much higher than based on clinical symptomatology alone. The use of both methods was not equivalent diagnostically (often they replace one another, but often also they supplement one another), and for that reason combined examination by both methods is frequently of high importance in practice, when the line of management is to be set down.

    Symptomatic lumbar intervertebral disc herniation (LDH) is rare in children and adolescents. To date, the treatments available for child and adolescent LDH, and the effect of each treatment, have not been fully reviewed. The purpose of this retrospective study is to report the etiology, familial history, presenting symptoms, level of herniation, duration of symptoms, radiological findings, as well as treatment methods and outcome. We retrospectively reviewed medical records of all patients with inclusion criteria of being younger than 20 years. (10-19 years); we used magnetic resonance imaging (MRI) to confirm lumbar disc herniations between 2013 and 2016. All patients were followed up for a minimum of 12 months and discharged if they remained almost asymptomatic for 6 months. All patients were treated conservatively and 6 patients they have progressive neurological deficit and persistent back pain, were treated with surgical procedures. The Visual Analogue Scale (VAS), as well as the Oswestry Disability Scale (ODS) and the modified Ashworth Scale (AS) were used to analyze physical examination findings both before and after treatment. To detect lumbar disc degeneration, we used the modified Pfirrmann grading system with MRI. All statistical analyses were performed with commercially available SPSS 15.0 software, while p ≤ 0.05 was considered statistically significant. A total of 70 cases with lumbar disc herniation have been treated. The mean age was 17.14 ± 2.15 years (range 9-19 years). The male to female ratio was 35:35. The mean duration of symptoms was 7.21 ± 1.69 months. The follow-up duration was 17.31 ± 4.17 months. The most common level was L4-5 in 38 (54%) patients and the second was L5-S1 in 24 (34%) patients. Subligamentous protruded discs were found in 42 (60%), extruded in 6 (9%), and disc bulge with intact annulus in 22 (31%) cases. VAS before treatment was 6.05 ± 0.83, while at 6 months after treatment it was 3.1 ± 0.6. However, at the first

    Physiotherapy is the treatment of choice in patients with symptoms caused by a lumbar disc herniation. In clinical practice a broad range of physiotherapeutic modalities has been revealed to be helpful. During the acute stage the efficacy of the McKenzie-concept, mobilisation therapies and traction has been demonstrated in randomized controlled trials with a blind assessor. In addition, pain reducing physical therapies such as cold or electrotherapy and non-steroidal anti-inflammatory drugs, analgesics and/or muscle relaxants are sensible initial accompanying treatments. The effectiveness of active physiotherapies such as training of local strength endurance of back and abdominal muscles has been proven in patients during the chronic stage. The indications for a in-patient rehabilitation programme, for surgery and the danger of developing chronic low back pain are discussed.

    Lumbar spondylolisthesis is one of the most common spinal diseases. It is caused by the anterior shift of a lumbar vertebrae relative to subjacent vertebrae. In current clinical practices, staging of spondylolisthesis is often conducted in a qualitative way. Although meyerding grading opens the door to stage spondylolisthesis in a more quantitative way, it relies on the manual measurement, which is time consuming and irreproducible. Thus, an automatic measurement algorithm becomes desirable for spondylolisthesis diagnosis and staging. However, there are two challenges. 1) Accurate detection of the most anterior and posterior points on the superior and inferior surfaces of each lumbar vertebrae. Due to the small size of the vertebrae, slight errors of detection may lead to significant measurement errors, hence, wrong disease stages. 2) Automatic localize and label each lumbar vertebrae is required to provide the semantic meaning of the measurement. It is difficult since different lumbar vertebraes have high similarity of both shape and image appearance. To resolve these challenges, a new auto measurement framework is proposed with two major contributions: First, a learning based spine labeling method that integrates both the image appearance and spine geometry information is designed to detect lumbar vertebrae. Second, a hierarchical method using both the population information from atlases and domain-specific information in the target image is proposed for most anterior and posterior points positioning. Validated on 258 CT spondylolisthesis patients, our method shows very similar results to manual measurements by radiologists and significantly increases the measurement efficiency.

    complex survey design of the NIS was taken into account by clustering on hospitals and assuming an exchangeable working correlation using the discharge weights supplied by the NIS. We accounted for multiple comparisons using the Bonferroni correction and an alpha level for statistical significance of . 0028. The prevalence of IBD is increasing among patients undergoing lumbar fusion, from 0.21% of all patients undergoing lumbar fusion in 1998 to 0.48% of all patients undergoing lumbar fusion in 2011 (pfusion surgery was associated with longer length of stay and greater hospitalization charges. Among patients who underwent lumbar fusion, IBD is a rare comorbidity that is becoming increasingly more common. Importantly, patients with IBD were not at increased risk of postoperative complications. Spine surgeons should be prepared to treat more patients with IBD and should incorporate the present findings into preoperative risk counseling and patient selection. Copyright © 2017 Elsevier Inc.

RESULTS This study was taken up to evaluate the management of lumbar spinal canal stenosis cases. The study was conducted from May 2012 to October 2014: A total of 86 patients of 55-70 age groups with degenerative LCS were followed prospectively from May 2012 to October 2014. All the treatment methods were explained to patients and treatment method was determined by patient’s choice. The sample is divided into two groups; 42 surgical and 44 conservative based on patient’s preference. Gender distribution in sample population was 75% male, 25% females. Most of the patients have more than one component. 47% patients had central canal stenosis and 48% had lateral, 32% far lateral stenosis. The mean operative time was 128 minutes. The mean operative blood loss was 293 mL. Average hospital stay was 15 days. 2% patients had dural tear, 11% patients had superficial surgical wound infection, which was treated by topical antiseptics. No complications were observed in conservative treatment. 34% patients received NSAID, 18% received ESI, 27% received PT, 15% received combined treatment. Assessment of ODI, SF 36 BP, SF 36 PF in study population and values are expressed in terms of mean and treatment effect/outcome was measured in terms of change in mean. Baseline mean values of surgical and conservative groups are similar. At periodic follow-ups, mean change is more in surgical group than conservative group. Hence, it is concluded that mean is effectively changed in surgical group than conservative groups. CONCLUSIONS Radiologic stenosis correlates poorly with clinical disability. As such, a thorough clinical examination of patients with lumbar spinal stenosis, including assessment of psychosocial factors, is crucial in determining the treatment outcome. The treatment effect for surgery was seen as early as 6 weeks

    To evaluate the clinical effects of over 5 year follow up of unilateral pedicle screw fixation with transforaminal lumbar interbody fusion(TLIF) in treating lumbar degenerative diseases. The clinical data of 24 patients with lumbar degenerative disease underwent unilateral pedicle screw fixation with transforaminal lumbar interbody fusion from March 2007 to October 2009, were retrospectively analyzed. There were 13 males and 11 females, aged from 34 to 68 years old with an average of 52 years. Postoperative pain and functional results were analyzed by the visual analogue scale(VAS) and Oswestry Disability Index(ODI). Radiological examination was obtained for each patient to assess the height of intervertebral space, postoperative intervertebral fusion conditions and general complications. All patients were followed up from 5 to 8 years with an average of 6.7 years. VAS scores of low back pain and leg pain decreased from preoperative 7.82±0.71, 8.42±1.24 to postoperative 1.87±0.81, 2.23±1.62, respectively( P degenerative diseases according to over 5 year follow up, however, its indications should be well considered. But the problems such as intervertebral space height of operated side loss and adjacent segment degeneration after unilateral pedicle screw fixation need further clinical study.

    The surgical strategies and methods used to treat dumbbell-shaped tumors located in the lumbar-foraminal region are controversial. Although a total facetectomy and combined intra- and extraspinal canal approach provide a wide operative field, facet fusion is required, which can be rather invasive. Here, we report a successful removal of a lumbar dumbbell-shaped schwannoma using a combined laminoplastic laminotomy with Wiltse's paraspinal surgical approach. This was performed under an operating microscope without a complete facetectomy, fusion, and posterior fixation. Briefly, we treated two patients with lumbar foraminal tumors, both dumbbell-shaped schwannomas located in the intra- and extradural portion. After a laminoplastic laminotomy, the intradural tumor was removed. The tumor located at the extracanalicular site was removed after drilling the pars interarticularis of the lamina, which was performed to enlarge the intervertebral foramen via Wiltse's paraspinal surgical approach. During surgery, facetectomy with posterior fixation was not needed to remove the intraforaminal component. There was no lumbar instability or complication after surgery. Our results suggest that a combined posterior laminoplastic laminotomy and Wiltse's paraspinal surgical approach is useful and less invasive for treating patients with lumbar foraminal tumors.

    With a steep increase in the number of instrumented spinal fusion procedures, there is a need for comparative data to develop evidence based treatment recommendations. Currently, the available data on cost and clinical effectiveness of the two most frequently performed surgeries for lumbar spondylolisthesis, transforaminal lumbar interbody fusion (TLIF) and posterior lumbar interbody fusion (PLIF), are not sufficient. Therefore, current guidelines do not advise which is the most appropriate surgical treatment strategy for these patients. Non-randomized studies comparing TLIF and PLIF moreover suggest that TLIF is associated with fewer complications, less blood loss, shorter surgical time and hospital duration. TLIF may therefore be more cost-effective. The results of this study will provide knowledge on short- and long-term clinical and economical effects of TLIF and PLIF procedures, which will lead to recommendations for treating patients with lumbar spondylolisthesis. Multicenter blinded Randomized Controlled Trial (RCT; blinding for the patient and statistician, not for the clinician and researcher). A total of 144 patients over 18 years old with symptomatic single level lumbar degenerative, isthmic or iatrogenic spondylolisthesis whom are candidates for LIF (lumbar interbody fusion) surgery through a posterior approach will be randomly allocated to TLIF or PLIF. The study will consist of three parts: 1) a clinical effectiveness study, 2) a cost-effectiveness study, and 3) a process evaluation. The primary clinical outcome measures are: change in disability measured with Oswestry Disability Index (ODI) and change in quality adjusted life years (QALY) measured with EQ-5D-5L. Secondary clinical outcome measures are: Short Form (36) Health Survey (SF-36), VAS back pain, VAS leg pain, Hospital Anxiety Depression Scale (HADS), complications, productivity related costs (iPCQ) and medical costs (iMCQ). Measurements will be carried out at five fixed time points (pre

    Full Text Available Background: Lumbar radiculopathy is a disease of the spinal nerve root generally accompanied by radicular pain in dermatomal distribution and/or neurologic symptoms. The previous studies were focusing on finding the disability and pain caused due to Lumbar Radiculopathy. This study is focusing on the disability, pain, range of motion of the spine and SLR. The objective of the study is to evaluate the effectiveness of Mckenzie method with TENS on reducing symptoms and disability of Lumbar radiculopathy. Methods: In the present prospective study patients with Lumbar radicular pain due to disc herniation or prolapse at level L4, L5 & S1 were randomized into two groups – Group A and Group B. the study included 40 patients, with 20 in each group. The selection criteria was based on the following - with age group 22-55years, both sexes – male and female, with radicular pain in L4, L5 & S1 dermatomes, disabling leg pain for 6-12 weeks duration, evidence of disc herniation confirmed on MR imaging. The radicular pain was measured using the SLR test, pain was measured using the VAS scale of 0 – 100, disability was measured using the MODI and Lumbar Spine ROM was measured using the MMST. Group-A were treated with McKenzie methods with TENS and Group-B were treated with general exercise with TENS. Results: This study showed that there was a significant reduction of pain on the VAS, improvement in SLR, lumbar spine range of motion using MMST and disability using MODI for both the groups. The statistical analysis found that experimental group showed earlier control of all the outcome measures when compared to controlled group at the end of the 6th week. Conclusion: After 6 weeks of Mckenzie method with TENS intervention for 30 minutes for 5 days in week the statistical analysis concluded that the experimental group had significantly faster rates of reducing the symptoms of lumbar radiculopathy and reducing the disability due to lumbar radiculopathy.

    Multiple studies have reported favorable short-term results after treatment of spondylolisthesis and other degenerative lumbar diseases with minimally invasive transforaminal lumbar interbody fusion. However, to our knowledge, results at a minimum of 5 years have not been reported. We determined (1) changes to the Oswestry Disability Index, (2) frequency of radiographic fusion, (3) complications and reoperations, and (4) the learning curve associated with minimally invasive transforaminal lumbar interbody fusion at minimum 5-year followup. We reviewed our first 124 patients who underwent minimally invasive transforaminal lumbar interbody fusion to treat low-grade spondylolisthesis and degenerative lumbar diseases and did not need a major deformity correction. This represented 63% (124 of 198) of the transforaminal lumbar interbody fusion procedures we performed for those indications during the study period (2003-2007). Eighty-three (67%) patients had complete 5-year followup. Plain radiographs and CT scans were evaluated by two reviewers. Trends of surgical time, blood loss, and hospital stay over time were examined by logarithmic curve fit-regression analysis to evaluate the learning curve. At 5 years, mean Oswestry Disability Index improved from 60 points preoperatively to 24 points and 79 of 83 patients (95%) had improvement of greater than 10 points. At 5 years, 67 of 83 (81%) achieved radiographic fusion, including 64 of 72 patients (89%) who had single-level surgery. Perioperative complications occurred in 11 of 124 patients (9%), and another surgical procedure was performed in eight of 124 patients (6.5%) involving the index level and seven of 124 patients (5.6%) at adjacent levels. There were slowly decreasing trends of surgical time and hospital stay only in single-level surgery and almost no change in intraoperative blood loss over time, suggesting a challenging learning curve. Oswestry Disability Index scores improved for patients with spondylolisthesis

    Lumbosacral nerve root anomalies are the leading cause of lumbar surgery failures. Although co-occurrence of lumbar spondylolysis and disc herniation is common, it is very rare to observe that a nerve root anomaly accompanies these lesions. A 49-year-old male patient presented with sudden-onset right leg pain. Examinations revealed L5/S1 lumbar spondylolysis and disc herniation. At preoperative period, he was also diagnosed with lumbosacral root anomaly. Following discectomy and root decompression, stabilization was performed. The complaints of the patient diagnosed with lumbosacral root anomaly at intraoperative period were improved at postoperative period. It should be remembered that in patients with lumbar disc herniation and spondylolysis, lumbar root anomalies may coexist when clinical and neurological picture is severe. Preoperative and perioperative assessments should be made meticulously to prevent neurological injury. PMID:25210343

    Full Text Available Background: DRX9000 spinal decompression is slightly known for treating chronic lumbar disc prolapse. The aim of the study was to examine the effectiveness of DRX9000spinal decompression on pain in chroniclumbar disc prolapse (CLDP. Methods: twenty male subjects with chronic lumbar disc prolapse,aged between 40:60 years were included in the study. They were assessed forpain intensity byslump test,straight leg raising test (SLR,modified Oswestery questionnaire (OQ and visual analogue scale (VAS. The study continued forsix weeks, the 20 patients were equally divided into two groups. Group A (experimental received spinal decompression, stability and McKenzie exercises; and ice, at a rate of 3 days per week, the duration of each session was 60 minutes. While group B (control were treated by exercises and ice only. Results: Majority of patients had positive findings in reducing pain clinically; however, statistically there was no significant difference. Conclusion: It can be concluded that spinal decompression has an effect, but not statistically significant in decreasing pain on patients with lumbar disc prolapse. This may be due to limited number of patients. We can recommend increasing the sample size to generalize the results, MRI scan follow up should be done after one year to determine if the effects are permanent or transient, comparing the effects of decompression between acute & chronic cases of lumbar disc prolapse, also male & female patients.

A total of 287 patients with lumbar intervertebral disc prolapse syndrome were randomly assigned to equilibrium acupuncture group (n = 143) and routine acupuncture group (n = 144) using SAS (Statistical Analysis System) Software. Patients of the equilibrium acupuncture group were treated by acupuncture stimulation of bilateral "Yaotong" point (at the middle site of the forehead) and those of the routine acupuncture group treated by acupuncture stimulation of Ashi-points, Weizhong (BL 40), Jiaji (EX-B 2), Shenshu (BL 23), etc. The treatment was conducted once daily for 20 days, then, 3 months' follow-up was given. Pain scores including pain rating index (PRI) and visual analogue scale (VAS) were given to the patients before and after the treatment using Chinese version of Short-Form of McGill Pain Questionnaire. Present pain intensity (PPI) was evaluated after the treatment. Before the treatment, no significant differences were found between the equilibrium acupuncture group and the routine acupuncture group in PRI and VAS scores (P > 0.05). Following the treatment, the pain symptom was apparently improved in both groups, and the rates of pain improvement (including excellent, good and moderate improvement rates) of the equilibrium acupuncture group were significantly higher than those of the routine acupuncture group from the 1st to the 4th treatment sessions, in the 20th treatment session and the 2nd follow-up (P equilibrium acupuncture group were significantly lower than those of the routine acupuncture group after the 18th and 20th sessions of treatment and the 3 months' follow-up (P equilibrium acupuncture group than in the routine acupuncture group in the 18th and 20th treatment sessions and the 2nd follow-up (P equilibrium-acupuncture" is relatively superior to routine acupuncture in the instant effect and long-term effect

    Full Text Available Background. Degenerative lumbar spinal stenosis (DLSS is a common cause of low back and leg pain in the elderly. Conservative treatment seldom results in sustained improvement.Methods. Fifty-six patients (33 women, 23 men older than 50 years (mean 67 years, range 51 to 82 years and with no prior low back surgery were treated from 1993 to 1999 for clinical and radiologic evidence of DLSS. The goal of this study was to describe the results of decompressive laminectomy with or without fusion in terms of reoperation, severity of back pain, leg pain and patient satisfaction. Answers to Swiss spinal stenosis questionnaires completed before surgery and one to five years afterwards were evaluated. Seven patients (12.5% with degenerative spondylolisthesis, scoliosis and/or more radical facetectomies received fusion.Results. Of the 56 patients in the original cohort, two were deceased and two had undergone reoperation by follow-up. Forty-eight patients answered questionnaires. Average duration of follow-up was 2.5 years. More than 70 percent of the respondents had no or only mild back or buttock pain at follow-up and more than 60 percent were able to walk more than 500 m. Added fusion reduced the incidence of low back pain and pain frequency, and increased walking distance (ANOVA.Conclusions. Eighty-one percent of patients were satisfied with the results of surgery and 87.5% would choose to have the operation again if they had the choice. Decompressive laminectomy for DLSS yields best results if instrumented fusion is included in the procedure.

    Relationships between patient satisfaction with nursing and patient clinical data have not been fully resolved in a Polish sample. Our objectives were to determine clinical factors associated with patient satisfaction with nursing and investigate differences between patients treated surgically for cervical or lumbar discopathy and degenerative changes. This prospective and cross-sectional study included 63 consecutively selected patients treated surgically for lumbar discopathy and degenerative spine disease and 41 patients undergoing surgery for cervical discopathy and degenerative spine disease from 1st June 2009 to 31st September 2010 in the Department of Neurosurgery and Neurotraumatology of Poznan University of Medical Sciences. In the first stage of this study, socio-demographic data, medical history, and clinical patient characteristics were collected. A minimum 12-month follow-up formed the second part. Nineteen patients with lumbar discopathy were excluded because they were unable to answer the questionnaire. Finally, 44 consecutively selected patients treated surgically for lumbar discopathy and 41 patients undergoing surgery due to cervical discopathy were evaluated with the Polish version of the Newcastle Satisfaction with Nursing Scale (NSNS-PL). In patients with cervical and lumbar discopathy, the average Experiences of Nursing Care Subscale (ENCS) scores were 82.0 (SD 15.1) and 79.0 (SD 13.5), respectively, whereas the average Satisfaction with Nursing Care Subscale (SNCS) scores were 75.6 (SD 18.1) and 74.4 (SD 16.8), respectively. The study groups did not differ in regards to NSNS subscales. Associations between ENCS and SNCS scores were confirmed in both patient groups (rS=.73, p<0.001 and rS=.73, p<0.001, respectively). Our study highlights the importance of assessing the association between patient characteristics and patient perception of quality of nursing care.

    Cross-sectional study. The aim of the study was to determine relationship between the degrees of radiologically demonstrated anatomical lumbar canal stenosis using magnetic resonance imaging (MRI) and its correlation with the patient's disability level, using the Oswestry Disability Index (ODI). The relationship between the imaging studies and clinical symptoms has been uncertain in patients suffering from symptomatic lumbar canal stenosis. There is a limited number of studies which correlates the degree of stenosis with simple reproducible scoring methods. Fifty patients were selected from 350 patients who fulfilled the inclusion criteria. The patients answered the national-language translated form of ODI. The ratio of disability was interpreted, and the patients were grouped accordingly. They were subjected to MRI; and the anteroposterior diameters of the lumbar intervertebral disc spaces and the thecal sac cross sectional area were measured. Comparison was performed between the subdivisions of the degree of lumbar canal stenosis, based on the following: anteroposterior diameter (three groups: normal, relative stenosis and absolute stenosis); subdivisions of the degree of central canal stenosis, based on the thecal sac cross-sectional area, measured on axial views (three groups: normal, moderately stenotic and severely stenotic); and the ODI outcome, which was also presented in 20 percentiles. No significant correlation was established between the radiologically depicted anatomical lumbar stenosis and the Oswestry Disability scores. Magnetic resonance imaging alone should not be considered in isolation when assessing and treating patients diagnosed with lumbar canal stenosis.

    The diagnostic utility of the 0.1 tesla resistive magnetic resonance imaging (MRI) system was studied for 78 lumbar disc hernias in surgically treated 70 patients. Myelographic appearance of the lumbar disc hernias fell into the following three categories: (1) medial type, compressing the thecal sac; (2) mediolateral type, compressing both the nerve root and thecal sac; and (3) lateral type, compressing the nerve root. MRI was performed in low-flip angle (LF) and saturation-recovery (SR) radiofrequency-pulse sequences for the midline and paramedian sagittal sections, respectively. A transverse section was found positive when the laterality of the disc hermia was obtained. A coronal section was found positive when high-intensity disc material compresisng the nerve root was recognized. Diagnostic capability of MRI was graded in three scores: Excellent- the optimal information was provided; Fair- some pieces of information was obtained, but not enough for diagnosis; Poor- the information was not helpful for diagnosis in deciding the operative procedure. Of 13 medial disc hernias, 84.6% was positive in the sagittal plane and 88.9% in the transverse plane. MRI was superior to myelography in 9 lesions. Of 38 mediolateral disc hernias, 84.2% were positive in the sagittal plane, 74.2% in the transverse plane, and 26.7% in the coronal plane. MRI was judged as excellent for 17 lesions, fair for 15 lesions, and poor for 6 lesions. Of 27 lateral disc hernias, 55.6% were positive in the sagittal plane, 50.0% in the transverse plane, and 30.0% in the coronal plane. MRI was judged as excellent for 4 lesions, fair for 11 lesions, and poor for 12 lesions. Resistive MRI system was of limited value in diagnosing surgical indication of lateral lumbar disc hernias, especially for small but painful lesions. (N.K.)

    Oxygen-ozone therapy is a minimally invasive treatment for lumbar disk herniation that exploits the biochemical properties of a gas mixture of oxygen and ozone. We assessed the therapeutic outcome of oxygen-ozone therapy and compared the outcome of administering medical ozone alone with the outcome of medical ozone followed by injection of a corticosteroid and an anesthetic at the same session. Six hundred patients were treated with a single session of oxygen-ozone therapy. All presented with clinical signs of lumbar disk nerve root compression, with CT and/or MR evidence of contained disk herniation. Three hundred patients (group A) received an intradiscal (4 mL) and periganglionic (8 mL) injection of an oxygen-ozone mixture at an ozone concentration of 27 micro g/mL. The other 300 patients (group B) received, in addition, a periganglionic injection of corticosteroid and anesthetic. Therapeutic outcome was assessed 6 months after treatment by using a modified MacNab method. Results were evaluated by two observers blinded to patient distribution within the two groups. A satisfactory therapeutic outcome was obtained in both groups. In group A, treatment was a success (excellent or good outcome) in 70.3% and deemed a failure (poor outcome or recourse to surgery) in the remaining 29.7%. In group B, treatment was a success in 78.3% and deemed a failure in the remaining 21.7%. The difference in outcome between the two groups was statistically significant (P ozone and periganglionic injection of steroids has a cumulative effect that enhances the overall outcome of treatment for pain caused by disk herniation. Oxygen-ozone therapy is a useful treatment for lumbar disk herniation that has failed to respond to conservative management.

    The aims of this preliminary study were to demonstrate the feasibility of in vivo diffusion tensor imaging (DTI) and fibre tracking (FT) of the lumbar nerve roots, and to assess potential differences in the DTI parameters of the lumbar nerves between healthy volunteers and patients suffering from disc herniation. Nineteen patients with unilateral sciatica related to posterolateral or foraminal disc herniation and 19 healthy volunteers were enrolled in this study. DTI with tractography of the L5 or S1 nerves was performed. Mean fractional anisotropy (FA) and mean diffusivity (MD) values were calculated from tractography images. FA and MD values could be obtained from DTI-FT images in all controls and patients. The mean FA value of the compressed lumbar nerve roots was significantly lower than the FA of the contralateral nerve roots (p=0.0001) and of the nerve roots of volunteers (p=0.0001). MD was significantly higher in compressed nerve roots than in the contralateral nerve root (p=0.0002) and in the nerve roots of volunteers (p=0.04). DTI with tractography of the lumbar nerves is possible. Significant changes in diffusion parameters were found in the compressed lumbar nerves. (orig.)

    Retrospective case-control study. To quantify the athletic performance profiles after lumbar discectomy (LD) in a cohort of National Basketball Association (NBA) players in comparison with a control group of matched NBA players who did not undergo LD during the same study period. LD provides symptomatic relief and improved functional outcomes in the majority of patients as assessed by validated measures such as Oswestry Disability Index, Visual Analog Scale, and Short Form-36 (SF-36). Among professional athletes, however, the goal of lumbar HNP treated by discectomy is not only to improve functional status but also, ultimately, to return the player to preinjury athletic performance levels. No study to date has compared the athletic performance profiles before and after discectomy in professional athletes. An analysis of NBA games summaries, weekly injury reports, player profiles, and press releases was performed to identify 24 NBA players who underwent LD for symptomatic lumbar HNP between 1991 and 2007. A 1:2 case: control study was performed using players without history of lumbar HNP who were matched for age, position, experience, and body mass index as control subjects (n = 48). Paired t tests were conducted on the following parameters: games played, minutes per game, points per 40 minutes, rebounds per 40 minutes, assists per 40 minutes, steals per 40 minutes, blocks per 40 minutes, and shooting percentage. For each athletic performance outcome, between-group comparisons evaluating preindex to postindex season performance were done (index season = season of surgery). In the LD group, 18 of 24 players (75%) returned to play again in the NBA, compared with 42 of 48 players (88%, P = 0.31) in the control group. One year after surgery, between-group comparisons revealed statistically significant increase in blocked shots per 40 minutes in the LD (0.18) versus control group (-0.33; P = 0.008) and a smaller decrease in rebounds per 40 minutes in the LD (-0

    A number of clinical studies have demonstrated that enlargement of the lumbar spinal canal is one of the effective surgical procedures for the treatment of the lumbar degenerative spondylolisthesis and provides a good result. In the present study, we have evaluated the long-term outcome of the enlargement of the lumbar canal without fusion in thirty eight patients with lumbar degenerative spondylolisthesis using three-dimensional computed tomography (3D-CT) The improvement rate was excellent in 80% of the patients (mean improvement ratio, 83%) according to the Japanese Orthopedic Association scoring system. We found that the sufficient enlargement of the canal was obtained by the surgery and maintained for a long period of time. The results from 3D-CT suggested that a round shape was maintained in the canal after the surgery because of pressures of the dura mater against to the bony canal. None of patients showed lumbar instability. In conclusion, enlargement of lumbar canal without fusion is useful for the treatment of lumbar degenerative spondylolisthesis, and the enlarged canal has been maintained for a long period of time after the surgery. The results demonstrated the clinical utility of 3D-CT to evaluate the preoperative and postoperative shape of the spine. (author)

    OBJECTIVE The study aimed to determine if the intraoperative segmental lordosis (as calculated on a cross-table lateral radiograph following a single-level transforaminal lumbar interbody fusion [TLIF] for degenerative spondylolisthesis/low-grade isthmic spondylolisthesis) is maintained at discharge and at 6 months postsurgery. METHODS The authors reviewed images and medical records of patients ≥ 16 years of age with a diagnosis of an isolated single-level, low-grade spondylolisthesis (degenerative or isthmic) with symptomatic spinal stenosis treated between January 2008 and April 2014. Age, sex, surgical level, surgical approach, and facetectomy (unilateral vs bilateral) were recorded. Upright standardized preoperative, early, and 6-month postoperative radiographs, as well as intraoperative lateral radiographs, were analyzed for the pelvic incidence, segmental lumbar lordosis (SLL) at the TILF level, and total LL (TLL). In addition, the anteroposterior position of the cage in the disc space was documented. Data are presented as the mean ± SD; a p value level using a bullet-shaped cage. A bilateral facetectomy was performed in 17 patients (20.2%), and 89.3% of procedures were done at the L4-5 and L5-S1 segments. SLL significantly improved intraoperatively from 15.8° ± 7.5° to 20.9° ± 7.7°, but the correction was lost after ambulation. Compared with preoperative values, at 6 months the change in SLL was modest at 1.8° ± 6.7° (p = 0.025), whereas TLL increased by 4.3° ± 9.6° (p level of surgery, and use of a bilateral facetectomy did not significantly affect postoperative LL. CONCLUSIONS Following a single-level TLIF procedure using a bullet-shaped cage, the intraoperative improvement in SLL is largely lost after ambulation. The improvement in TLL over time is probably due to the decompression part of the procedure. The approach, level of surgery, bilateral facetectomy, and position of the cage do not seem to have a significant effect on LL achieved

    Field study, cross-sectional study to measure the posture and sEMG of the lumbar spine during office work for a better understanding of the lumbar spine within such conditions. There is high incidence of low back pain in office workers. Currently there is little information about lumbar posture and the activity of lumbar muscles during extended office work. Thirteen volunteers were examined for around 2h of their normal office work. Typical tasks were documented and synchronised to a portable long term measuring device for sEMG and posture examination. The correlation of lumbar spine posture and sEMG was tested statistically. The majority of time spent in office work was sedentary (82%). Only 5% of the measured time was undertaken in erect body position (standing or walking). The sEMG of the lumbar muscles under investigation was task dependent. A strong relation to lumbar spine posture was found within each task. The more the lumbar spine was flexed, the less there was activation of lumbar muscles (P sitting postures. Because of very low activation of lumbar muscles while sitting, the load is transmitted by passive structures like ligaments and intervertebral discs. Due to the viscoelasticity of passive structures and low activation of lumbar muscles, the lumbar spine may incline into de-conditioning. This may be a reason for low back pain.

    Side effects of iohexol lumbar myelography have been analyzed with respect to the influence of the type of radiological abnormality, sex and age in a group of 200 patients. Headache, postural headache, nausea and back/leg pain were significantly more frequent in patients without definite radiological abnormalities. Postural headache, nausea, dizziness and mental symptoms were more frequent in women, while headache, postural headache, nausea, dizziness, minor mental symptoms (i.e. anxiety or depression) and pain became less frequent with age. This pattern is similar to that reported after lumbar puncture. Young women without definite clinical signs of nerve root lesions probably have the greatest risk of experiencing side effects after iohexol lumbar myelography. (orig.)

    Congenital agenesis of lumbar vertebrae was diagnosed in a day-old female lamb based on radiology and clinical examinations. There was no neurological deficit in hindlimb and forelimb associated with standing disability. Radiography of the abdominal region revealed absence of lumbar vertebrae. Necropsy confirmed clinical and radiographic results. No other anomaly or agenesis was seen macroscopically in the abdominal and thoracic regions as well as vertebral column. Partial absence of vertebral column has been reported in human and different animal species, as an independent occurrence or associated with other organs anomalies. The latter has been designated as caudal regression syndrome. Vertebral agenesis may arise from irregularity in the differentiation of somites to the sclerotome or sclerotome to the vertebral primordium. Most of the previously reported cases of agenesis were related to the lumbosacral region, lonely or along with other visceral absences. This case was the first report of congenital agenesis of lumbar vertebrae in a lamb.

    Retrospective radiographic analysis of lumbar spine range of motion (ROM) after monosegmental fusion and posterior dynamic stabilization at the level L4-L5. Comparison of segmental ROM at the index level and the cranial and caudal adjacent levels and of global lumbar spine ROM after monosegmental fusion and posterior dynamic stabilization. The postulated advantage of nonfusion technology compared with fusion is based on the assumption that preservation of motion at the treated segment reduces the incidence of adjacent segment effects. Therefore, it is imperative to provide evidence that dynamic stabilization devices avoid hypermobility at the adjacent segments because this might substantiate a protective effect on the adjacent segments. Twenty-six patients with low back pain and claudication due to degenerative instability at the level L4-L5 with concomitant spinal stenosis were treated either with decompression and Dynesys (n = 11) or with decompression and fusion (n = 15). All patients underwent flexion/extension radiographs before surgery and at latest follow-up. ROM was assessed at the index level (L4-L5), the cranial/caudal adjacent levels (L3-L4/L5-S1), and at the lumbar spine from L2 to S1. There was a significant reduction of the global ROM of the lumbar spine (L2-S1) and the segmental ROM at the index level (L4-L5) in the fusion group, whereas adjacent level ROM did not change significantly. In the Dynesys group, no significant changes of global lumbar spine ROM (L2-S1) and segmental ROM (index level and cranial/caudal adjacent levels) were seen. This study shows that neither monosegmental instrumented fusion nor monosegmental posterior dynamic stabilization with Dynesys alter the ROM of the cranial and caudal adjacent levels. Consequently, monosegmental posterior dynamic stabilization with Dynesys has no effect with regard to adjacent segment mobility compared with monosegmental fusion.

    Although spondylolisthesis was traditionally treated with posterior lumbar interbody fusion (PLIF), minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) was recently proposed as an alternative treatment for spondylolisthesis. However, no studies have focused on the comparison of these 2 techniques' outcome on spondylolisthesis.The operative reports and perioperative data of patients who underwent single-level primary open PLIF (n = 29) and MIS-TLIF (n = 26) for I/II spondylolisthesis were retrospectively evaluated. Patients' demographics, operative blood loss, hospital length of stay, creatine kinase (CK) level, radiographic fusion, complications, and patient-reported outcomes were evaluated. Radiographic fusion was assessed using the Bridwell grading criteria. Preoperative and postoperative patient-reported outcomes included the visual analog scale (VAS) and Oswestry Disability Index (ODI).Average follow-up was 28 ± 3.6 months (range 24-32 months). Bed rest time, hospital stay, estimated blood loss, and operative time in the MIS-TLIF group were significantly lower than those in the PLIF group (P  .05).Compared with PLIF, MIS-TLIF for grade I/II spondylolisthesis can achieve similar reduction and fusion results with better short-term quality of life, shorter hospital stays, less estimated blood loss, and shorter operative times.

    [Purpose] To present the outcome of a patient, having sciatica and MRI-verified disc herniation/sequestration who underwent Chiropractic BioPhysics ® (CBP ® ) protocol designed to improve the lumbar lordosis. [Subject and Methods] A 56-year-old male suffered from chronic low back pain and recent sciatica due to lumbar disc herniation despite being under continuous care from three previous chiropractors. Radiographic analysis revealed a lumbar hypolordosis and MRI confirmed disc herniation and sequestration at L4-L5. Generalized decreased lumbar range of motion and multiple positive orthopedic and neurologic tests were present. [Results] After 26 treatments of CBP lumbar extension traction over 9-weeks a total reduction of the disc herniation and sequestration occurred with concomitant improvement in neurologic symptoms. Continuing maintenance treatments, an 8 year follow-up shows no relapse of condition and patient remained in good health. [Conclusion] A patient with lumbar disc herniation/sequestration was successfully treated with CBP technique procedures including lumbar extension traction that achieved a significant healing of herniation and significant reduction in symptoms not obtained following traditional chiropractic procedures alone. The quick reduction in lumbar disc herniation would appear to be related to a segmental disc unloading force produced during extension traction procedures for increasing the lumbar curvature.

    2014-01-01

    Full Text Available Most chronic low back pain is the result of degeneration of the lumbar intervertebral disc. Ligustrazine, an alkaloid from Chuanxiong, reportedly is able to relieve pain, suppress inflammation, and treat osteoarthritis and it has the protective effect on cartilage and chondrocytes. Therefore, we asked whether ligustrazine could reduce intervertebral disc degeneration. To determine the effect of ligustrazine on disc degeneration, we applied a rat model. The intervertebral disc degeneration of the rats was induced by prolonged upright posture. We found that pretreatment with ligustrazine for 1 month recovered the structural distortion of the degenerative disc; inhibited the expression of type X collagen, matrix metalloproteinase (MMP-13, and MMP3; upregulated type II collagen; and decreased IL-1β, cyclooxygenase (COX-2, and inducible nitric oxide synthase (iNOS expression. In conclusion, ligustrazine is a promising agent for treating lumbar intervertebral disc degeneration disease.

    To determine the probability of spontaneous disc regression among each type of lumbar herniated disc, using a systematic review. Medline, Cochrane Library, CINAHL, and Web of Science were searched using key words for relevant original articles published before March 2014. Articles were limited to those published in English and human studies. Articles had to: (1) include patients with lumbar disc herniation treated conservatively; (2) have at least two imaging evaluations of the lumbar spine; and (3) exclude patients with prior lumbar surgery, spinal infections, tumors, spondylolisthesis, or spinal stenosis. Two reviewers independently extracted study details and findings. Thirty-one studies met the inclusion criteria. Furthermore, if the classification of herniation matched the recommended classification of the combined Task Forces, the data were used for combined analysis of the probability of disc regression of each type. Nine studies were applicable for probability calculation. The rate of spontaneous regression was found to be 96% for disc sequestration, 70% for disc extrusion, 41% for disc protrusion, and 13% for disc bulging. The rate of complete resolution of disc herniation was 43% for sequestrated discs and 15% for extruded discs. Spontaneous regression of herniated disc tissue can occur, and can completely resolve after conservative treatment. Patients with disc extrusion and sequestration had a significantly higher possibility of having spontaneous regression than did those with bulging or protruding discs. Disc sequestration had a significantly higher rate of complete regression than did disc extrusion. © The Author(s) 2014.

    Patients with lumbar disc disease may present with low back pain, pain that radiates down to the lower extremity (radiculopathy), and leg pain that increases with ambulation (neurogenic claudication). Patients may first undergo diagnostic studies (magnetic resonance imaging, computed tomographic examinations) to determine whether there is any significant nerve root or thecal sac compression. Increasingly, patients with low back pain with/without radiculopathy are being screened by nurses rather than by neurologists or neurosurgeons/orthopedists. Recognition of the basic neurological symptoms and signs of lumbar disc disease is critical to manage and triage these patients. The neurological examination includes evaluation of the straight leg raising test (SLR/Lasegue Maneuver) and assessment of: motor function [grade 0 (no motion) to grade 5 (normal motion)], reflexes [Patellar and Achilles levels graded 0 (absent) to grade 4+ (clonus)], sensory loss (pin prick, light touch, position, and vibration), and cerebellar function (tandem gait, heel-shin, and finger-nose-finger testing). Learning to read MR and CT studies for disc herniations is critical. Nonsurgical discs include those that are minimally protruding or bulging. Alternatively, surgical disc herniations when correlated with significant neurological findings are extruded (ruptured through the annulus) or sequestrated (migrated beyond the disc space following rupture). Familiarity with symptoms, neurological signs, and radiographic presentations for patients with lumbar disc disease is critical for nurses. Here, we review the important factors nurses should know to better recognize, triage, and treat patients with lumbar disc disease.

    In the lumbar region the longissimus thoracis and iliocostalis lumborum are separated by the erector spinae aponeurosis and its ventral reflection--the lumbar intermuscular aponeurosis. Lumbar fibres of the longissimus arise from the ilium and the lumbar intermuscular aponeurosis and insert into the accessory processes and proximal ends of the transverse processes of the lumbar vertebrae. Lumbar fibres of iliocostalis insert into the costal elements of the first four lumbar vertebrae. The lum...

    The authors make a retrospective study of a series of 200 patients who had been surgically treated, within a period of 26 months, for a lumbar discal pathology. Twenty of these (20%) were over 65 years old. A similar study was carried out in a rheumatological unit over a period of three years, and has included 266 patients, 21 of whom (7,8%) were older than 65. The comparison of both these series permits us to make some considerations concerning the frequency of this pathology after the age of 65, its clinical presentation and its treatment, which, as for the younger adult, must be surgical when the correct treatment fails and when a complication appears.

    Fifty-seven patients were examined with CT 5 years after primary myelography for disabling sciatica and suspected herniated lumbar disk. Forty were in an operated group, 22 with good and 18 with poor results evaluated by occupational handicap (21) 5 years after surgery. Seventeen patients had myelography indicating disk herniation, but were treated conservatively, 9 with good and 8 with poor result. Various spinal dimensions measured at CT did not correlate with outcome. Operated patients had narrower canals than others, and male canals were broader than those in females. Increased amount of scar tissue at L4 level correlated with poor result (p=0.008). Operated patients with poor result had more advanced lateral stenosis than those treated conservatively (p<0.001). Patients with good result after operation had more degeneration observed on CT of erector spinae muscle than those treated conservatively with good outcome. Only 9% of operated patients did not have muscle degeneration. A tendency for more frequent recurrent disk herniations could be ssen for conservatively treated patients. The narrowing of the spinal canal 5 years after operation did not correlate with the 5-year outcome. (orig.).

    Instrumented lumbar fusion can provide immediate stability and assist in satisfactory arthrodesis in patients who have pain or instability of the lumbar spine. Lumbar adjunctive fusion with decompression is often a good procedure for surgical management of degenerative spondylolisthesis (DS). Among various lumbar fusion techniques, lumbar interbody fusion (LIF) has an advantage in that it maintains favorable lumbar alignment and provides successful fusion with the added effect of indirect decompression. This technique has been widely used and represents an advancement in spinal instrumentation, although the rationale and optimal type of LIF for DS remains controversial. We evaluated the current status and role of LIF in DS treatment, mainly as a means to augment instrumentation. We addressed the basic concept of LIF, its indications, and various types including minimally invasive techniques. It also has acceptable biomechanical features, and offers reconstruction with ideal lumbar alignment. Postsurgical adverse events related to each LIF technique are also addressed. PMID:27169496

    To present a radiculopathy case due to unilateral facet hypertrophy developing three years after a lumbar disc hernia operation. A fifty two-year-old female patient, who had been operated on for a left L5-S1 herniated lumbar disc three years ago, was hospitalized and re-operated with a diagnosis of unilateral facet hypertrophy. She had complaints of left leg pain and walking restrictions for the last six months. Left Straight Leg Raising test was positive at 40 degrees , left ankle dorsiflexion muscle strength was 4/5, left Extensor Hallucis Longus muscle strength was 3/5, and left Achilles reflex was hypoactive. Lumbar spinal Magnetic Resonance Imaging revealed left L5-S1 facet hypertrophy. Lumbar radiculopathy due to lumbar facet hypertrophy is a well-known neurological condition. Radicular pain develops during the late postoperative period following lumbar disc hernia operations that are often related to recurrent disc herniation or to formation of post-operative scar tissue. In addition, it can be speculated that unilateral facet hypertrophy, which may develop after a disc hernia operation, might also be one of the causes of radiculopathy.

    The posterior lumbar interbody fusion (PLIF) and transforaminal lumbar interbody fusion (TLIF) techniques are commonly used surgical methods for wide indications such as degeneration or trauma. Although they are rarely required for lumbar disk disease in younger patients, there are a few children and adolescents who are indicated for PLIF or TLIF for other reasons, such as congenital severe stenosis with or without lumbar instability that requires wide decompression or severe bony spur that need to be removed. In such cases, different pathophysiology and outcomes are expected compared with adult patients. We retrospectively reviewed data of 23 patients who underwent PLIF or TLIF surgery when less than 20 years old. Clinical and radiographic outcomes were assessed during a mean of 36.4 months follow-up period. The indications of lumbar interbody fusion, success of fusion, complications, and visual analog scale (VAS) were analyzed. Radiographs of all patients taken 6 months after the surgery showed fusion. Clinical outcome was also satisfactory, with improvement of VAS score from 7.7 preoperatively to 2.3 at 6 months after surgery. Only one patient had reoperation due to adjacent segment disease. For adolescent patients with severe bony spur, massive central disk rupture, or severe spondylolisthesis, lumbar interbody fusion surgery has good surgical outcome with few complications.

    Full Text Available OBJECTIVE: To determinate whether a surgical protocol with immediate extensive debridement, closed irrigation system and antibiotic therapy would be effective to achieve healing of deep wound infection without removing the instrumentation.METHODS: Prospective cohort study with 19 patients presenting degenerative spinal stenosis or degenerative spondylolisthesis, who developed infection after posterior lumbar arthrodesis. The diagnosis was confirmed by a microbial culture from subfascial lumbar fluid and/or blood. Patients were treated with a protocol of wound exploration, extensive flushing and debridement, placement of a closed irrigation system that was maintained for five days and intravenous antibiotics. The instrumentation system was not removed.RESULTS: Mean age was 59.31 (±13.17 years old and most patients were female (94.7%; 18/19. The mean period for the identification of the infection was 2 weeks and 57.9% underwent a single wound exploration. White blood count, erythrocyte sedimentation rate and C-reactive protein showed a significant decrease post-treatment when compared to pre-treatment values. A significant reduction of erythrocyte sedimentation rate and C-reactive protein was also observed at the final evaluation. No laboratory test was useful to predict the need for more than one debridement.CONCLUSION: Patients with wound infection after instrumentation can be treated without removal of the instrumentation through wound exploration, extensive flushing, debridement of necrotic tissue, closed irrigation system during 5 days and proper antibiotic therapy. The blood tests were not useful to predict surgical re-interventions.

    The lumbar multifidus muscle provides an important contribution to lumbar spine stability, and the restoration of lumbar multifidus function is a frequent goal of rehabilitation. Currently, there are no reliable and valid physical examination procedures available to assess lumbar multifidus function among patients with low back pain. To examine the inter-rater reliability and concurrent validity of the multifidus lift test (MLT) to identify lumbar multifidus dysfunction among patients with low back pain. A cross-sectional analysis of reliability and concurrent validity performed in a university outpatient research facility. Thirty-two persons aged 18 to 60 years with current low back pain and a minimum modified Oswestry disability score of 20%. Study participants were excluded if they reported a history of lumbar spine surgery, lumbar radiculopathy, medical red flags, osteoporosis, or had recently been treated with spinal manipulation or trunk stabilization exercises. Concurrent measures of lumbar multifidus muscle function at the L4-L5 and L5-S1 levels were obtained with the MLT (index test) and real-time ultrasound imaging (reference standard). The inter-rater reliability of the MLT was examined by measuring the level of agreement between two blinded examiners. Concurrent validity of the MLT was investigated by comparing clinicians' judgments with real-time ultrasound imaging measures of lumbar multifidus function. Inter-rater reliability of the MLT was substantial to excellent (κ=0.75 to 0.81, p≤.01) and free from errors of bias and prevalence. When performed at L4-L5 or L5-S1, the MLT demonstrated evidence of concurrent validity through its relationship with the reference standard results at L4-L5 (rbis=0.59-0.73, p≤.01). The MLT generally failed to demonstrate a relationship with the reference standard results from the L5-S1 level. Our results provide preliminary evidence supporting the reliability and validity of the MLT to assess lumbar multifidus

    Lumbar disc arthroplasty has become a popular modality for the treatment of degenerative disc disease. The dimensions of the implants are based on early published geometrical measurements of vertebrae; the majority of these were cadaver studies. The fit of the prosthesis in the intervertebral space is of utmost importance. An undersized implant may lead to subsidence, loosening and biomechanical failure due to an incorrect center of rotation. The aim of the present study was to measure the dimensions of lumbar vertebrae based on CT scans and assess the accuracy of match in currently available lumbar disc prostheses. A total of 240 endplates of 120 vertebrae were included in the study. The sagittal and mediolateral diameter of the upper and lower endplates were measured using a digital measuring system. For the levels L4/L5 and L5/S1, an inappropriate size match was noted in 98.8% (Prodisc L) and 97.6% (Charite) with regard to the anteroposterior diameter. Mismatch in the anterior mediolateral diameter was noted in 79.3% (Prodisc L) and 51.2% (Charite) while mismatch in the posterior mediolateral diameter was observed in 91.5% (Prodisc L) and 78% (Charite) of the endplates. Surgeons and manufacturers should be aware of the size mismatch of currently available lumbar disc prostheses, which may endanger the safety and efficacy of the procedure. Larger footprints of currently available total disc arthroplasties are required.

    Lumbar spondylolysis and isthmic spondylolisthesis occur most commonly at only one spinal level. The authors report on 13 cases of lumbar spondylolysis with spondylolisthesis at multiple levels. During July 2007-March 2012, multiple-level spondylolysis associated with spondylolisthesis was diagnosed in 13 patients (10 male, 3 female) at Qilu Hospital of Shandong University. The mean patient age was 43.5 ± 14.6 years. The duration of low-back pain was 11.7 ± 5.1 months. Spondylolysis occurred at L-2 in 2 patients, L-3 in 4 patients, L-4 in all patients, and L-5 in 5 patients. Spondylolysis occurred at 3 spinal levels in 3 patients and at 2 levels in 10 patients. All patients had spondylolisthesis at 1 or 2 levels. Japanese Orthopaedic Association and visual analog scale scores were used to evaluate preoperative and postoperative neurological function and low-back pain. All patients underwent pedicle screw fixation and interbody fusion or direct pars interarticularis repair. Both low-back pain scores improved significantly after surgery (p spondylolysis and spondylolisthesis occurred more often in men. Most multiplelevel lumbar spondylolysis occurred at 2 spinal levels and was associated with sports, trauma, or heavy labor. Multiplelevel lumbar spondylolysis occurred mostly at L3-5; associated spondylolisthesis usually occurred at L-4 and L-5, mostly at L-4. The treatment principle was the same as that for single-level spondylolisthesis.

    Full text: Introduction Lumbar disc herniation can be treated with lumbar micro-invasive herniotomy under CT control through transforaminal posterolateral or transchannel approach. Percutaneous access by the fine needle probe in combination with X-ray and CT control is a micro - invasive surgery of the spine, which may be considered as an alternative to traditional surgery. The advantages of this method are: the small diameter of the used probe (not more than 16 G or 1,5 mm), allowing the dermal incision to be only a few millimeters as well as the realization of transchannel access, thereby reducing the risk for susceptible ligament injury and the avoidance of bone lesions on the back arc or neighboring muscular structures. Materials and Methods: The aim of this study is to demonstrate that percutaneous lumbar herniotomy under CT control and on posterolateral and foraminal disc herniation with symptoms of pain and root irritation, leads to a significant improvement of the complaints at times immediately postinterventsional and within 6 months ( D1 , D2, D7 , 1, 2 , 6 months) . This lecture presents 55 consecutive patients with symptoms of pain and root irritation, who have made significant progress after percutaneous lumbar herniotomy under CT control and who did not have satisfactory results despite an adapted medical treatment. All patients were clinically evaluated by using visual analogue scales (VAS) for pain, lumbar and root irritation, as well as by MR images postoperatively. Results: All 55 patients showed immediate postoperative improvement of clinical symptoms and signs. Postoperative MR images also show root decompression. It is not reported about complications during the procedure. After the first week it was noted a reduction in average VAS values of 71% and 67% in patients treated for posterolateral and foraminal herniated disc; in medial disc hernia it was noted an average reduction of only 45% . Six months after micro surgery treatment a positive

    Ice hockey players have a high incidence of lumbar spine disorders; however, there is no evidence in the literature to guide the treatment of an ice hockey player with a herniated lumbar disc. To determine the performance-based outcomes in professional National Hockey League (NHL) athletes with a lumbar disc herniation after either nonsurgical or surgical treatment. Descriptive epidemiological study. Athletes in the NHL with a lumbar disc herniation were identified through team injury reports and archives on public record. The return-to-play rate, games played per season, points per game, and performance score for each player were determined before and after the diagnosis of a lumbar disc herniation. Statistical analysis was used to compare preinjury and postinjury performance measures for players treated with either nonsurgical or surgical treatment. A total of 87 NHL players met the inclusion criteria; 31 underwent nonoperative care, 48 underwent a discectomy, and 8 underwent a single-level fusion. The return-to-play rate for all players was 85%. There was a significant decrease in performance in all players after a lumbar disc herniation in games played per season, points scored per game, and performance score. A comparison of the posttreatment results for the nonsurgical and surgical patient groups revealed no significant difference in performance measures. Notably, the lumbar fusion group did not show a decrease in games played per season or performance score after surgery, likely secondary to a small sample size. National Hockey League players with a lumbar disc herniation have a high return-to-play rate regardless of the type of treatment; however, performance-based outcomes may decrease compared with preinjury levels. The study data suggest that a lumbar fusion is compatible with a return to play in the NHL, which is in contrast to other professional sports.

    Lumbar disc prolapse, protrusion, and extrusion are the most common causes of nerve root pain and surgical interventions, and yet they account for less than 5% of all low back problems. The typical rationale for traditional surgery is that it is an effort to provide more rapid relief of pain and disability. It should be noted that the majority of patients do recover with conservative management. The primary rationale for any form of surgery for disc prolapse associated with radicular pain is to relieve nerve root irritation or compression due to herniated disc material. The primary modality of treatment continues to be either open or microdiscectomy, although several alternative techniques, including automated percutaneous mechanical lumbar discectomy, have been described. There is, however, a paucity of evidence for all decompression techniques, specifically alternative techniques including automated and laser discectomy. A systematic review of the literature of automated percutaneous mechanical lumbar discectomy for the contained herniated lumbar disc. To evaluate and update the effectiveness of automated percutaneous mechanical lumbar discectomy. The available literature on automated percutaneous mechanical lumbar discectomy in managing chronic low back and lower extremity pain was reviewed. The quality assessment and clinical relevance criteria utilized were the Cochrane Musculoskeletal Review Group criteria, as utilized for interventional techniques for randomized trials, and the criteria developed by the Newcastle-Ottawa Scale criteria for observational studies.The level of evidence was classified as good, fair, and limited or poor, based on the quality of evidence scale developed by the U.S. Preventive Services Task Force (USPSTF). Data sources included relevant literature identified through searches of PubMed and EMBASE from 1966 to September 2012, and manual searches of the bibliographies of known primary and review articles.

    Full Text Available Abstract We report the case of a 25-year-old Caucasian woman with symptomatic monostotic fibrous dysplasia of the fourth lumbar vertebral body. The patient suffered from a five-week history of progressive low back pain, radiating continuously to the left leg. Her medical history and physical and neurological examination did not demonstrate any significant abnormalities. Radiographs, computed tomography and magnetic resonance imaging revealed an osteolytic expansive lesion with a cystic component of the fourth lumbar vertebral body. Percutaneous transpedicular biopsy showed histological characteristics of fibrous dysplasia superimposed by the formation of aneurysmal bone cyst components. The patient was treated by subtotal vertebrectomy of the L4 vertebral body with anterior reconstruction and her postoperative course was uncomplicated. To our knowledge, this is the first reported case of a monostotic fibrous dysplasia with superimposed secondary aneurysmal bone cysts of a lumbar vertebral body.

    OBJECT Decompression without fusion for degenerative lumbar stenosis is an effective treatment for both the pain and disability of neurogenic claudication. Iatrogenic instability following decompression may require further intervention to stabilize the spine. The authors review the incidence of postsurgical instability following lumbar decompression, and assess the impact of surgical technique as well as study design on the incidence of instability. METHODS A comprehensive literature search was performed to identify surgical cohorts of patients with degenerative lumbar stenosis, with and without preexisting spondylolisthesis, who were treated with laminectomy or minimally invasive decompression without fusion. Data on patient characteristics, surgical indications and techniques, clinical and radiographic outcomes, and reoperation rates were collected and analyzed. RESULTS A systematic review of 24 studies involving 2496 patients was performed, assessing both open laminectomy and minimally invasive bilateral canal enlargement. Postoperative pain and functional outcomes were similar across the various studies, and postoperative radiographie instability was seen in 5.5% of patients. Instability was seen more frequently in patients with preexisting spondylolisthesis (12.6%) and in those treated with open laminectomy (12%). Reoperation for instability was required in 1.8% of all patients, and was higher for patients with preoperative spondylolisthesis (9.3%) and for those treated with open laminectomy (4.1%). CONCLUSIONS Instability following lumbar decompression is a common occurrence. This is particularly true if decompression alone is selected as a surgical approach in patients with established spondylolisthesis. This complication may occur less commonly with the use of minimally invasive techniques; however, larger prospective cohort studies are necessary to more thoroughly explore these findings.

    Minimally invasive surgical techniques have been developed to minimize tissue damage, reduce narcotic requirements, decrease blood loss, and, therefore, potentially avoid prolonged immobilization. Thus, the purpose of the present retrospective study was to assess the safety and efficacy of a minimally invasive posterior approach with transforaminal lumbar interbody debridement and fusion plus pedicle screw fixation in lumbar spondylodiscitis in comparison to an open surgical approach. Furthermore, treatment decisions based on the patient´s preoperative condition were analyzed. 67 patients with lumbar spondylodiscitis treated at our department were included in this retrospective analysis. The patients were categorized into two groups based on the surgical procedure: group (MIS) minimally invasive lumbar spinal fusion (n = 19); group (OPEN) open lumbar spinal fusion (n = 48). Evaluation included radiological parameters on magnetic resonance imaging (MRI), laboratory values, and clinical outcome. Preoperative MRI showed higher rates of paraspinal abscess (35.5 vs. 5.6%; p = 0.016) and multilocular location in the OPEN group (20 vs. 0%, p = 0.014). Overall pain at discharge was less in the MIS group: NRS 2.4 ± 1 vs. NRS 1.6 ± 1 (p = 0.036). The duration of hospital stay was longer in the OPEN than the MIS group (19.1 ± 12 days vs. 13.7 ± 5 days, p = 0.018). The open technique is effective in all varieties of spondylodiscitis inclusive in epidural abscess formation. MIS can be applied safely and effectively as well in selected cases, even with epidural abscess.

    Changes in thoracolumbar fascial thickness, structure and shear strain are associated with lower back pain (LBP). Therapeutic taping techniques such as Kinesio-Taping (KT) are increasingly used to treat LBP, albeit with variable effects and unclear mechanisms. However, evidence for quantifying how treatment effects in vivo fascia properties is inadequate. We therefore aimed to explore taping mechanisms using an in vivo ultrasound measurement. Thoracolumbar ultrasound videos of known orientations and positions were taken from 12 asymptomatic participants (8 males and 4 females, aged 22.9 ± 3.59) while performing velocity-guided lumbar flexion with and without KT applied. An automated algorithm using cross-correlation to track contiguous tissue layers across sequential frames in the sagittal plane, was developed and applied to two movements of each subject in each taping condition. Differences of inter-tissue movements and paracutaneous translation at tissue boundaries were compared. Significant reduction in the mean movement of subcutaneous tissue during lumbar flexion before and after taping was found. There was no difference in other observed tissue layers. Tissue paracutaneous translations at three boundaries were significantly reduced during lumbar flexion when KT was applied (skin-subcutaneous: 0.25 mm, p < 0.01; subcutaneous-perimuscular tissue: 0.5 mm, p = 0.02; and perimuscular-muscle: 0.46, p = 0.05). No overall reduction in lumbar flexion was found (p = 0.10). KT reduced subcutaneous inter-tissue movement and paracutaneous translation in the superficial thoracolumbar fascia during lumbar flexion, and the relationship of such difference to symptomatic change merits exploration. Combining ultrasound data with muscle activation information may be useful to reveal potential mechanisms of therapeutic taping in patients with LBP. Copyright © 2016 Elsevier Ltd.

    Full Text Available Minimally invasive (MI lumbar decompression became a common approach to treat lumbar stenosis. This approach may potentially mitigate postoperative increases in segmental motion. The goal of this study was to evaluate modifications to segmental motion in the lumbar spine following a MI unilateral approach as compared to traditional facet-sparing and non-facet sparing decompressions. Six human lumbar cadaveric specimens were used. Each specimen was tested in flexion-extension 0 N and 400 N of follower preload, axial rotation, and lateral bending. Each testing condition was evaluated following three separate interventions at L4-L5: 1 Minimally invasive decompression, 2 Facet-sparing, bilateral decompression, and 3 Bilateral decompression with a wide facetectomy. Range of motion following each testing condition was compared to intact specimens. Both MI and traditional decompression procedures create significant increases in ROM in all modes of loading. However, when compared to the MI approach, traditional decompression produces significantly larger increase in ROM in flexion-extension (p<0.005 and axial rotation (p<0.05. It additionally creates increased ROM with lateral bending on the approach side (p<0.05. Lateral bending on the non-approach side is not significantly changed. Lastly, wide medial facet removal (40% to 50% causes significant hypermobility, especially in axial rotation. While both MI and traditional lumbar decompressions may increase post-operative ROM in all conditions, a MI approach causes significantly smaller increase in ROM. With an MI approach, increased movement with lateral bending is only toward the approach side. Further, non-facet sparing decompression is further destabilizing in all loading modes.

    We compared the analgesic effects of intravenous (IV) paracetamol with that of dexketoprofen on postoperative pain and morphine consumption during the first 24 hour after a lumbar disk surgery. This prospective, placebo-controlled, double blind study investigated the analgesic effects of IV paracetamol and dexketoprofen on postoperative pain, morphine consumption, and morphine-related side effects after a lumbar disk surgery. Sixty American Society of Anesthesiologists 1 or 2 status patients scheduled for elective lumbar disk surgery under general anesthesia were included in the study. Patients were treated using patient-controlled analgesia with morphine for 24 hours after a lumbar disk surgery and randomized to receive IV paracetamol 1 g, dexketoprofen 50 mg, or isotonic saline (placebo). The primary endpoint was pain intensity measured by the visual analogue scale, and secondary endpoints were morphine consumption and related side effects. Pain intensity was lower in the dexketoprofen group (P=0.01) but not in the paracetamol group (P=0.21) when compared with the control group. Cumulative morphine consumption and morphine-related side effects did not reveal significant differences between the groups. The study showed that pain intensity during 24 hours after the lumbar disk surgery was significantly lowered by dexketoprofen, but not with paracetamol, as a supplemental analgesic to morphine patient-controlled analgesia when compared with controls.

    To evaluate the surgical outcome in terms of functional and subjective recovery, patients who needed discectomies at L1-L2, L2-L3 and L3-L4 levels were compared with an age and sex-matched group of patients who required L4-L5 and L5-S1 discectomies. We prospectively enrolled 50 consecutive patients, referred to our center, who had L1-L2, L2-L3 and L3-L4 herniations and required surgical intervention. Likewise, a comparative group of 50 consecutive patients with herniations at L4-L5 and L5-S1 were selected. All 100 patients were treated and followed for a 1 year period. Physical examination findings as well as Oswestry Disability Questionnaire before surgery were recorded. After 1 year, patients were requested to fill the same questionnaire. Significant decline in the Oswestry Disability Index (ODI) scores was considered to be a measure of functional improvement and recovery. The mean age of patients with upper lumbar disc herniation (L1-L2, L2-L3, L3-L4) was 45.7 years and patients with lower lumbar disc herniation (L4-L5, L5-S1) had a mean age of 41.2 years. There was no statistically significant difference in age between the two groups. The preoperative Oswestry Disability (ODI) Index score had a statistically significant impact on ODI score improvement after surgery in both lower and upper lumbar disc groups. All 100 patients with either lower or upper lumbar disc herniation had statistically significant ODI change after surgical intervention (P disability (ODI of 21-40%) did not show significant improvement, while patients with ODI greater than 40% had significant reduction (P = 0.018). Surprisingly, as many as 25% of the former had even an increase in ODI scores after surgery. Gender was also a conspicuous factor in determining the surgical outcome of patients with upper lumbar disc herniation, and male patients had more reduction in ODI score than female patients (P = 0.007). Since the functional recovery in patients with herniated lumbar disc, especially

    Post hoc analysis of a randomized controlled trial. To characterize the morphology and clinical relevance of vertebral endplate changes (VEPC) following limited lumbar discectomy with or without implantation of a bone-anchored annular closure device (ACD). Implantation of an ACD following limited lumbar discectomy has shown promise in reducing the risk of recurrent herniation in patients with large annular defects. However, the interaction between the ACD and the lumbar endplate over time is not well understood. Patients undergoing limited lumbar discectomy with large postsurgical annular defects were randomized intraoperatively to receive additional ACD implantation or limited lumbar discectomy only (Controls). VEPC morphology, area, and volume were assessed with low-dose computed tomography preoperatively and at 1 and 2 years follow-up. Of 554 randomized patients, the as-treated population consisted of 550 patients (267 ACD, 283 Controls). VEPC were preoperatively identified in 18% of patients in the ACD group and in 15% of Controls. At 2 years, VEPC frequency increased to 85% with ACD and 33% in Controls. Device- or procedure-related serious adverse event (8% vs. 17%, P = 0.001) and secondary surgical intervention (5% vs. 13%, P ACD group over Controls. In the ACD group, clinical outcomes were comparable in patients with and without VEPC at 2 years follow-up. In the Control group, patients with VEPC at 2 years had higher risk of symptomatic reherniation versus patients without VEPC (35% vs. 19%, P ACD reduces risk of postoperative complications despite a greater frequency of VEPC. VEPC were associated with higher risk of symptomatic reherniation in patients treated with limited lumbar discectomy, but not in those who received additional ACD implantation. 2.

    Objectives: To examine general practitioners' attitudes to plain lumbar spine radiographic examinations. Design: A postal questionnaire consisting of questions on background data and doctors' opinions about plain lumbar spine radiographic examinations, as well as eight vignettes (imaginary patient cases) presenting indications for lumbar radiography, and five vignettes focusing on the doctors' willingness to request lumbar radiography on the basis of patients' age and duration of symptoms. The data were analysed according to the doctor's age, sex, workplace and the medical school of graduation. Setting: Finland. Subjects: Six hundred and fifteen randomly selected physicians working in primary health care (64% of original target group). Results: The vignettes revealed that the use of plain lumbar radiographic examination varied between 26 and 88%. Patient's age and radiation protection were the most prominent factors influencing doctors' decisions to request lumbar radiographies. Only slight differences were observed between the attitudes of male and female doctors, as well as between young and older doctors. Doctors' willingness to request lumbar radiographies increased with the patient's age in most vignettes. The duration of patients' symptoms had a dramatic effect on the doctor's decision: in all vignettes, doctors were more likely to request lumbar radiography when patient's symptoms had exceeded 4 weeks. Conclusions: General practitioners commonly use plain lumbar spine radiographic examinations, despite its limited value in the diagnosis of low back pain. Further consensus and medical education is needed to clarify the indications for plain lumbar radiographic examination

    Problems of lumbar spondylolisthesis treatment are many surgical tactics, elderly patient, osteoporosis, complications and recurrence of the symptoms. PLIF (posterior lumbar interbody fusion) and PS (pedicle screw) fixation technique for lumbar spondylolisthesis provide good patient satisfaction. Good outcome has been reported by only laminectomy alone, but patient satisfaction becomes worse year after year. The role of instrumentation for lumbar spondylolisthesis is decompression of the nerve root, correction of lumbar pathologies, bony fusion and early mobilization. We show our surgical technique and long term outcome of PLIF with PS for lumbar spondylolisthesis. Three hundred and fifty cases of lumbar spondylolisthesis were operated on in Department of Neurosurgery, Fujita Health University during the period of from December 1992 to August 2008. Patient background: age 16-84 years old (mean 62.5), Gender: male 153, female 197. Follow-up period 1-180 months (mean 61.2). Degenerative: 255, Isthmic: 63, Dysplastic: 10, Fracture: 5 and scoliosis 16 cases. Surgical procedure was PS with interbody fusion cage: 331, Hybrid cage (titanium cage with hydroxyapatite) 314, PS with Cerabone: 2 and PS with autograft: 17. CT was done to evaluate bony fusion postoperatively. Post operative improvements by JOA (Japan Orthopedic Association) score is 11.4 before surgery, 24.1 (post op. within 2 years), 25.4 (post op. 2-5 years), 25.0 (post op. 5-10 years) and 22.4 (post op. 10-15 years). Significant improvements were observed in %Slip and Slip angle but no remarkable change was observed in lumbar lordotic angle by postoperative X-ray evaluation. No root injury, and systemic complication except 4 cases of cerebrospinal fluid (CSF) leakage during surgery. Two cases were reoperated in whom cage with autograft migration due to pseudoarthrosis. Two cases had to undergo screw and cage system removal due to infection. Two cases of adjacent level stenosis had to undergo operation 10

    To compare the effectiveness and changes of sagittal spino-pelvic parameters between minimally invasive transforaminal lumbar interbody fusion and conventional open posterior lumbar interbody fusion in treatment of the low-degree isthmic lumbar spondylolisthesis. Between May 2012 and May 2013, 86 patients with single segmental isthmic lumbar spondylolisthesis (Meyerding degree I or II) were treated by minimally invasive transforaminal lumbar interbody fusion (minimally invasive group) in 39 cases, and by open posterior lumbar interbody fusion in 47 cases (open group). There was no significant difference in gender, age, disease duration, degree of lumbar spondylolisthesis, preoperative visual analogue scale (VAS) score, and Oswestry disability index (ODI) between 2 groups (P>0.05). The following sagittal spino-pelvic parameters were compared between 2 groups before and after operation: the percentage of slipping (PS), intervertebral height, angle of slip (AS), thoracolumbar junction (TLJ), thoracic kyphosis (TK), lumbar lordosis (LL), sagittal vertical axis (SVA), spino-sacral angle (SSA), sacral slope (SS), pelvic tilt (PT), and pelvic incidence (PI). Pearson correlation analysis of the changes between pre- and post-operation was done. Primary healing of incision was obtained in all patients of 2 groups. The postoperative hospital stay of minimally invasive group [(5.1 ± 1.6) days] was significantly shorter than that of open group [(7.2 ± 2.1) days] (t = 2.593, P = 0.017). The patients were followed up 11-20 months (mean, 15 months). The reduction rate was 68.53% ± 20.52% in minimally invasive group, and was 64.21% ± 30.21% in open group, showing no significant difference (t = 0.725, P = 0.093). The back and leg pain VAS scores, and ODI at 3 months after operation were significantly reduced when compared with preoperative ones (P 0.05). The postoperative other sagittal spino-pelvic parameters were significantly improved (P 0.05), but there was no significant

    Lumbar spinal stenosis in the presence of degenerative spondylolisthesis is generally treated by means of surgery. The role of lumbar decompression without fusion is not clear. Therefore, the aim of this study was to assess whether patients who undergo decompression alone have a favourable outcome without the need for a subsequent fusion. This is a prospective cohort study with single blinding of 83 consecutive patients with lumbar stenosis and degenerative spondylolisthesis treated by decompression, without fusion, using a spinous process osteotomy. Blinded observers collected pre- and post-operative Oswestry Disability Index (ODI), EuroQol Five Dimensions (EQ-5D), and visual analogue scale (VAS) for back and leg pain scores prospectively. Failures for this study were those patients who required a subsequent lumbar fusion procedure at the decompressed levels. Statistical analysis was performed using paired t test and Mann-Whitney test. There were 36 males and 47 females with a mean age of 66 years (range 35-82). The mean follow-up was 36 months (range 19-48 months). The mean pre-operative ODI, EQ-5D, and VAS scores were 52 [standard deviation (SD) 18], 0.25 (SD 0.30), and 61 (SD 22), respectively. All mean scores improved post-operatively to 38 (SD 23), 0.54 (SD 0.34) and 36 (SD 27), respectively. There was a statistically significant improvement in all scores (p ≤ 0.0001). Nine patients (11 %) required a subsequent fusion procedure and five patients (6 %) required revision decompression surgery alone. Our study's results show that a lumbar decompression procedure without arthrodesis in a consecutive cohort of patients with lumbar spinal stenosis with degenerative spondylolisthesis had a significant post-operative improvement in ODI, EQ-5D, and VAS. The rate of post-operative instability and subsequent fusion is not high. Only one in 10 patients in this group ended up needing a subsequent fusion at a mean follow-up of 36 months, indicating that fusion is

    Large lumbar or lumbosacral (LS) disc herniations usually expand from the paramedian space to the neuroforamen and compress both the transversing (lower) and the exiting (upper) nerve roots, thus leading to bi-radicular symptoms. Bi-radicular involvement is a statistically significant risk factor for poor outcome in patients presenting with far lateral or foraminal disc herniation after facet preserving microdecompression. There is evidence showing that patients suffering from large lumbar disc herniations treated with interbody fusion have significant superior results in comparison with those who received a simple discectomy. We report our experiences on managing large LS disc herniation with bi-radicular symptoms by transforaminal lumbar interbody fusion (TLIF) using one diagonal fusion cage with unilateral pedicle screw/rod fixation. Twenty-three patients who suffered from single level lumbar or LS disc herniation with bi-radicular symptoms treated with unilateral decompression and TLIF using one diagonal fusion cage with ipsilateral pedicle screw/rod fixation operated between January 2005 and December 2009, were included in this study. Operation time and blood loss were recorded. The pain and disability status were pre- and postoperatively evaluated by the visual analog score (VAS) and Oswestry Disability Index (ODI). Interbody bony fusion was detected by routine radiographs and computed tomography scan. Adjacent segment degeneration was detected by routine radiographs and magnetic resonance imaging examination. Overall outcomes were categorized according to modified Macnab classification. The patients were followed up for an average of 44.7 months. Pain relief in the VAS and improvement of the ODI were significant after surgery and at final followup. No severe complications occurred during hospital stay. Interbody bony fusion was achieved in every case. No cage retropulsion was observed, while 3 cases experienced cage subsidence. Adjacent segment degeneration

    Full Text Available Spondylolysis of the lumbar spine has traditionally been treated using a variety of techniques ranging from conservative care to fusion. Direct repair of the defect may be utilized in young adult patients without significant disc degeneration and lumbar instability. We used minimally invasive techniques to place pars interarticularis screws with the use of an intraoperative CT scanner in three young adults, including two athletes. This technique is a modification of the original procedure in 1970 by Buck, and it offers the advantage of minimal muscle dissection and optimal screw trajectory. There were no intra- or postoperative complications. The detailed operative procedure and the postoperative course along with a brief review of pars interarticularis defect treatment are discussed.

    Objective: To chronicle the conservative treatment and management of an osteoporotic patient presenting with acute back pain resulting from a lumbar compression fracture. Clinical features: A 74-year old male presented with acute back pain in the thoracolumbar region after an episode of lifting. Radiographic evaluation revealed generalized demineralization and a moderate wedge compression fracture at L1. Intervention and outcome: The conservative treatment approach included postural education, activity modification, interferential current, taping into extension, Graston Technique®, and rehabilitative exercise prescription. Outcome measures included verbal pain rating scale, medication use, and a return to activities of daily living (ADLs). The patient attained long-term symptom resolution with no recurrence of pain at 12 month follow-up. Summary: A combination of conservative rehabilitation strategies may be successfully implemented to treat osteoporotic patients with mild to moderate osteoporotic vertebral compression fracture of the lumbar spine.

    Full Text Available Intervertebral disc herniation of the lumbar spine is a common disease presenting with low back pain and involving nerve root radiculopathy. Some neurological symptoms in the majority of patients frequently improve after a period of conservative treatment. This has been regarded as the result of a decrease of pressure exerted from the herniated disc on neighboring neurostructures and a gradual regression of inflammation. Recently, with advances in magnetic resonance imaging, many reports have demonstrated that the herniated disc has the potential for spontaneous regression. Regression coincided with the improvement of associated symptoms. However, the exact regression mechanism remains unclear. Here, we present 2 cases of lumbar intervertebral disc herniation with spontaneous regression. We review the literature and discuss the possible mechanisms, the precipitating factors of spontaneous disc regression and the proper timing of surgical intervention.

    Side effect incidences after ambulatory (22G needle and two h bed rest) and after non-ambulatory (22 and 20G needles and 20 h bed rest) lumbar iohexol myelography have been estimated and compared. Headache incidence was significantly greater in ambulatory (50%, n=107) as compared to nonambulatory myelography (26%, n=58). Headaches in the ambulatory group tended to be of shorter duration and the difference between severe headaches in ambulatory and non-ambulatory groups was not significant. Serious adverse reactions did not occur and none of the ambulatory patients required readmission because of side effects. The headache was predominantly postural and occurred significantly earlier in the ambulatory group. Headache incidence was significantly greater after 20G needle myelography (44%, n=97) as compared to 22G needle iohexol myelography (26%, n=58). The results support the hypothesis that CSF leakage is a major cause of headache after lumbar iohexol myelography. (orig.)

    Full Text Available Lumbar spinal stenosis results from the progressive combined narrowing of the central spinal canal, the neurorecesses, and the neuroforaminal canals. In the absence of prior surgery, tumor, or infection, the spinal canal may become narrowed by bulging or protrusion of the intervertebral disc annulus, herniation of the nucleus pulposis posteriorly, thickening of the posterior longitudinal ligament, hypertrophy of the ligamentum flavum, epidural fat deposition, spondylosis of the intervertebral disc margins, or a combination of two or more of the above factors. Patients with spinal stenosis become symptomatic when pain, motor weakness, paresthesia, or other neurologic compromise causes distress. In one case, we administrated oriental medical treatment with acupuncture treatment and herb-medicine. Oriental medical treatment showed desirable effect on lumbar spinal stenosis.

    A 9 yr old castrated male golden retriever weighing 36 kg was presented for evaluation of progressive left pelvic limb paresis and fecal and urinary incontinence. MRI demonstrated an extradural, ovoid mass compressing the lumbar spinal cord. Surgical excision of the mass was performed. Histologically, the mass was consistent with hemangiosarcoma with no involvement of the adjacent vertebrae. The dog underwent a doxorubicin-based chemotherapy protocol with the addition of oral cyclophosphamide. After completion of chemotherapy, the dog was evaluated q 4 mo for restaging. Clinicopathological evidence of primary tumor recurrence or metastatic disease was not detected for 15 mo after initial diagnosis and treatment. To the authors' knowledge, this is the first report of a primary extradural hemangiosarcoma in the lumbar vertebral column in a dog. The clinical presentation, diagnosis, treatment, and outcome are also discussed.

    Although there are currently less invasive techniques available for the treatment of spinal injuries, open surgery is still required in many cases. Vascular injuries occurring during lumbar spine surgery, although uncommon, are of great importance due to their potential gravity. Clinical manifestations vary from an acute hemorrhagic shock that needs urgent treatment to save the patient's life, to insidious injuries or an asymptomatic evolution, and should be studied to choose the best therapeutic alternative. Four cases are reported that represent this range of possibilities and emphasize the importance of a careful surgical technique during lumbar spine interventions, and the need for high clinical suspicion, essential for the early diagnosis of these vascular complications. The current therapeutic options are also discussed. Copyright © 2014 SECOT. Published by Elsevier Espana. All rights reserved.

    Full Text Available Degree of hernia size influence on final result of PLME in 34 patients with discogenic neurocompressive lumbar spinal syndrome was detected. In medical center "Endoscopic Neurosurgery" from 2006 to 2010 we examined and treated 34 patients with hernia size from 6 to 8 mm by CT data. Patients were from 19 to 49 years of age. Average age was 35.9 ± 1.5 years. Males – 16 (47.1%, females – 18 (52.9%. Disease duration – 5.53 ± 0.44 months with duration of last exacerbation – 1.87 ± 0.21 months. Duration of conservative therapy is 4.6 ± 2.1 weeks. During survey and objec¬tive examination we determined pain syndrome intensity, pain location, degree of spinal static – dynamic function disorder. Neurological examination determined severity of sensory and motor disorders. Pain syndrome intensity, quality of life in patients before and after surgery, surgery effectiveness were determined by common scales: VAS, OSWESTRY, Roland - Morris, McNab. Before PLME we evaluated preoperative spondylograms performed with functional load. Height of intervertebral fissure was determined by these images. By SCT and MRI data we measured hernia size, its shape and location as well as intervertebral disk dehydration degree. For PLME performance we used neodymium laser with aluminum garnet (Dorinyer Fibertom Medilas 4060 with wave-length of 1.06 micrometers. In the next period of observation after PLME its effectiveness was 79%, and in 3-5 years - 76%. At the same time it must be emphasized that 75% of patients with discogenic neurocompressive lumbar spinal syndrome significantly and for a long time improved their life quality avoiding more traumatic surgery. Satisfactory results with PLM use in the nearest future could be obtained in 79% of patients, in the remote term - in 76% of patients with large hernia size.

    Retrospective review of patients who had pyogenic discitis and were managed surgically. To analyze the bacteriology, pathology, management and outcome of pyogenic discitis of the lumbar region treated surgically. Surgical management of pyogenic discitis is still an infrequently used modality of treatment. A total of 42 patients comprised of 33 males and 9 females who had pyogenic discitis with a mean age of 51.61 years (range, 16-75 years) were included in this study. All the cases were confirmed as having pyogenic discitis by pus culture report and histopathological examination. The mean follow-up period was 41.9 months. Debridement and posterior lumbar interbody fusion with autologous iliac bone graft was done in all cases. Thirteen (30.95%) patients had other medical co-morbidities. Five cases had a previous operation of the spine, and three cases had a history of vertebral fracture. Three patients were operated for gynaecological problems, and four cases had a history of urological surgery. L4-5 level was the most frequent site of pyogenic discitis. The most common bacterium isolated was Staphylococcus aureus (S. aureus). Radiologically good fusion was seen in the majority of patients. Pyogenic discitis should be suspected in people having pain and local tenderness in the spinal region with a rise in inflammatory parameters in blood. The most common bacterium was S. aureus, but there were still a greater number of patients infected with other types of bacteria. Therefore, antibiotics therapy should be started only after isolating the bacteria and making the culture sensitivity report.

    Multilevel lumbar stenosis, in which 1 level requires stabilization due to spondylolisthesis, is routinely treated with multilevel open laminectomy and fusion. We hypothesized that a minimally invasive (MI) decompression is biomechanically superior to open laminectomy and may allow decompression of the level adjacent the spondylolisthesis without additional fusion. To study the mechanical effect of various decompression procedures adjacent to instrumented segments in cadaver lumbar spines. Conditions tested were (1) L4-L5 instrumentation, (2) L3-L4 MI decompression, (3) addition of partial facetectomy at L3-L4, and (4) addition of laminectomy at L3-L4. Flexibility tests were performed for range of motion (ROM) analysis by applying nonconstraining, pure moment loading during flexion-extension, lateral bending, and axial rotation. Compression flexion tests were performed for motion distribution analysis. After instrumentation, MI decompression increased flexion-extension ROM at L3-L4 by 13% (P = .03) and axial rotation by 23% (P = .003). Partial facetectomy further increased axial rotation by 15% (P = .03). After laminectomy, flexion-extension ROM further increased by 12% (P = .05), a 38% increase from baseline, and axial rotation by 17% (P = .02), a 58% increase from baseline. MI decompression yielded no significant increase in segmental contribution of motion at L3-L4, in contrast to partial facetectomy and laminectomy (<.05). MI tubular decompression is biomechanically superior to open laminectomy adjacent to instrumented segments. These results lend support to the concept that in patients in whom a multilevel MI decompression is performed, the fusion might be limited to the segments with actual instability.

    Sixteen patients were operated on for lumbar pain and pain radiating into the sciatic nerve distribution. In all 16, when the anulus fibrosus was incised, soft, gray disc material extruded under pressure like toothpaste being squeezed from a tube. This syndrome of myxomatous degeneration is a distinct entity, different from classical fibrotic disc degeneration or herniated nucleus pulposus. Surgical removal associated with partial facetectomy produced excellent results. The concept of incompetence of the anulus fibrosis is discussed.

    One of the major clinical issues encountered after lumbar spinal fusion is the development of adjacent segment pathology (ASP) caused by increased mechanical stress at adjacent segments, and resulting in various radiographic changes and clinical symptoms. This condition may require surgical intervention. The incidence of ASP varies with both the definition and methodology adopted in individual studies; various risk factors for this condition have been identified, although a significant contro...

    Spondylolisthesis with or without spondylolysis is common in the lumbar spine. Associated fracture in the pedicle ('pediculolysis') is unusual. The margins of pedicular stress fractures, like spondylolysis, usually appear sclerotic. A patient with a pedicular stress fracture with minimal marginal sclerosis suggesting an injury of recent onset is presented here. There was associated bilateral spondylolysis. The findings in this patient suggest that established pediculolysis probably represents a stress fracture that has failed to heal. (authors)

    Here we provide the most extensive metric and morphological analysis performed to date on the Neandertal lumbar spine. Neandertal lumbar vertebrae show differences from modern humans in both the vertebral body and in the neural arch, although not all Neandertal lumbar vertebrae differ from modern humans in the same way. Differences in the vertebral foramen are restricted to the lowermost lumbar vertebrae (L4 and L5), differences in the orientation of the upper articular facets appear in the uppermost lumbar vertebrae (probably in L1 and L2-L3), and differences in the horizontal angle of the transverse process appear in L2-L4. Neandertals, when compared to modern humans, show a smaller degree of lumbar lordosis. Based on a still limited fossil sample, early hominins (australopiths and Homo erectus) had a lumbar lordosis that was similar to but below the mean of modern humans. Here, we hypothesize that from this ancestral degree of lumbar lordosis, the Neandertal lineage decreased their lumbar lordosis and Homo sapiens slightly increased theirs. From a postural point of view, the lower degree of lordosis is related to a more vertical position of the sacrum, which is also positioned more ventrally with respect to the dorsal end of the pelvis. This results in a spino-pelvic alignment that, though different from modern humans, maintained an economic postural equilibrium. Some features, such as a lower degree of lumbar lordosis, were already present in the middle Pleistocene populations ancestral to Neandertals. However, these middle Pleistocene populations do not show the full suite of Neandertal lumbar morphologies, which probably means that the characteristic features of the Neandertal lumbar spine did not arise all at once.

    A series of 235 patients examined by lumbar CT because of sciatica or other low back disorder was studied. The need of additional examinations and correlations to surgical findings were evaluated. Inadequate information was the cause of additional examination, mostly myelography in 20 patients (8,5%). It was concluded that lumbar CT is a suitable first examination of the lumbar spine in sciatica and low back pain. The indications to complementary myelography and its benefit are discussed.

    To evaluate the stenotic condition of the lumbar spinal canal, MRI was compared with myelography and with discography in 102 patients, all of whom underwent surgical exploration. Various pathologic conditions were studied including 50 cases of herniated nucleus pulposus, 39 cases of lumbar canal stenosis (central, peripheral type or combined type), and 13 cases of spondylolisthesis (degenerative, spondylolytic, and dysplastic type). High correlation was detected between the T2 weighted mid-sagittal image of the thecal sac and the lateral view of a full-column myelogram, but subtle changes such as adhesive changes, or redundancy, or anomalous changes of the nerve roots were more clearly demonstrated on myelograms than on MRI. Actually some of these changes could not be detected on MRI. The degrees of disc degeneration were classified into five grades according to the signal intensity and the irregularity of the disc on the T2-weighted image. The MRI evaluation of disc degeneration in this series was similar to that of the discography. However, MRI could not replace discography for identifying the source of pain in symptomatic patients. Although MRI might be the imaging modality for diagnostic screening and for detecting stenotic conditions of the lumbar spinal canal, it will not be able to replace myelography and/or discography for determining indication for surgery and preferred surgical approach.

    Study Design Cadaveric biomechanical study. Objectives Quantify the effects of vertebral body augmentation on biomechanics under axial compression by a total disc replacement (TDR) implant. Summary of Background Data TDR is a surgical alternative to lumbar spinal fusion to treat degenerative disc disease. Osteoporosis in the adjacent vertebrae to the interposed TDR may lead to implant subsidence or vertebral body fracture. Vertebral augmentation is used to treat osteoporotic compression fracture. The study sought to evaluate whether vertebral augmentation improves biomechanics under TDR axial loading. Methods Forty-five L1-L5 lumbar vertebral body segments with intact posterior elements were used. Peripheral quantitative computed tomography scans were performed to determine bone density, block randomizing specimens by bone density into augmentation and control groups. A semi-constrained keeled lumbar disc replacement device was implanted providing 50% endplate coverage. Vertebral augmentation of 17.6 ± 0.9% vertebral volume fill with Cortoss was performed on augmentation group. All segments underwent axial compression at a rate of 0.2 mm/s to 6mm. Results The load-displacement response for all specimens was non-linear. Subfailure mechanical properties with augmentation were significantly different from control; in all cases the augmented group was 2× higher than control. At failure, the maximum load and stiffness with augmentation was not significantly different from control. The maximum apparent stress and modulus with augmentation were 2× and 1.3× greater than control, respectively. The subfailure stress and apparent modulus with augmentation was moderately correlated with bone density while the control subfailure properties were not. The augmented maximum stress was not correlated with bone density, while the control was weakly correlated. The maximum apparent modulus was moderately correlated with bone density for both the augmented and control groups

    For elderly patients, posterior lumbar interbody fusion (PLIF) or transforaminal lumbar interbody fusion (TLIF) is usually performed to treat lumbar degenerative diseases. However, some patients exhibit pseudarthrosis following such procedures. The anabolic agent teriparatide is an approved treatment for promoting bone formation in osteoporotic patients. Our multicenter, prospective randomized study assessed the role of once-weekly teriparatide administration on patient outcomes following interbody fusion. Patients were females who were ≥50 years of age, had a bone mineral density (BMD) of teriparatide, administered subcutaneously starting at week 1, for 6 months postoperatively (the teriparatide arm), or no teriparatide (the control arm). Blinded radiographic evaluations were performed using dynamic radiography and computed tomography (CT) and assessed by modified intention-to-treat analysis and per-protocol analysis. Clinical and neurological symptoms were evaluated using the Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOA-BPEQ) and the Oswestry Disability Index (ODI). Seventy-five patients were randomized to treatment, and 66 patients completed treatment. At 4 months postoperatively, bone fusion in the 2 center CT slices was significantly higher in the teriparatide arm compared with the control arm in the age-adjusted modified intention-to-treat analysis and was significantly higher at 6 months in the per-protocol analysis. Radiographic examinations showed no disc-space narrowing and no intervertebral disc instability. JOA-BPEQ and ODI results were improved postoperatively in both treatment arms. Weekly administration of teriparatide promoted bone formation at the surgical fusion site and decreased bone resorption, as indicated by bone metabolic marker results, within the early postoperative period. Our findings suggest that combining lumbar interbody fusion and teriparatide treatment may be an effective option for managing lumbar

    Study Design: Prospective cohort study. Objective: Endplate lesions though have been implicated in the genesis of lumbar disc herniation (LDH), very little is known regarding their clinical course. Thus, the present study is aimed to investigate the incidence and types of endplate failure (EPF) in LDH and its correlation with the clinical symptoms and prognosis. Methods: Clinical and magnetic resonance imaging (MRI) features of 66 patients with isolated single level LDH were studied. Three-dimensional fast spoiled gradient (3D FSPGR) MRI and computed tomography scans were used to identify the bony and cartilaginous EPF. Twenty-five patients were operated on and 41 patients were treated conservatively. Changes in the pain score, function and neurology were noted at 3, 6, 12, 24, and 36 weeks. Results: Endplate lesions were observed in 64 patients (96.9%), including bony endplate failure (bony failure) in 47 patients (71.2%) and isolated cartilaginous endplate lesions in 17 patients (25.7%). Bony failure group had similar pain and functional scores but more severe neurological deficit at the initial evaluation. Clinical parameters improved in all groups, but the recovery was lesser in conservatively treated bony failure patients. Conclusion: Endplate lesions are commonly associated with symptomatic LDH. Presence of bony failure can increase neurological deficit and reduce the chance of recovery with conservative management. The 3D FSPGR sequence of MRI can be successfully used for detection of the endplate lesions in the herniated disc. PMID:28660105

    The purpose of this study was to report the functional outcomes of young active soccer players with lumbar spondylolysis undergoing conservative treatment. Between 2002 and 2004, all soccer players diagnosed with spondylolysis with a minimum 2-year follow-up were retrospectively reviewed. All patients were treated nonoperatively with cessation of sports activity and rehabilitation for 3 months. The rehabilitation protocol was identical for all patients and emphasized strengthening of abdominal muscles, stretching of the hamstrings, "core" stability exercises, and trunk rotational movements in a pain-free basis. Those patients with pain at rest and with daily life activities were also treated with a thoracolumbar orthosis. Symptomatic patients or those with positive SPECT were not allowed to return to sports and continued the rehabilitation protocol for 3 more months. The mean time of cessation of sports activity was 3.9 months (SD 0.8) and 5.2 months (SD 2.1) for a complete return to sports. At the 2-year follow-up, 28 patients (82%) obtained excellent results, 4 (12%) good results, 1 patient (3%) a fair result, and 1 patient (3%) a poor result. Conservative treatment of spondylolysis in young soccer players with cessation of sports and rehabilitation, with or without thoracolumbar orthosis, was associated with excellent functional results in terms of return to sports and level of achievable physical activity.

    There is limited evidence to support the use of high-volume lumbar taps over lower-volume taps in the diagnosis of normal pressure hydrocephalus. The purpose of this study is to detect whether the volume of CSF removed from patients undergoing high-volume diagnostic lumbar tap test for normal pressure hydrocephalus is significantly associated with post-lumbar tap gait performance. This retrospective study included 249 consecutive patients who underwent evaluation for normal pressure hydrocephalus. The patients were analyzed both in their entirety and as subgroups that showed robust response to the lumbar tap test. The volume of CSF removed was treated as both a continuous variable and a discrete variable. Statistical tests were repeated with log-normalized volumes. This study found no evidence of a relationship between the volume of CSF removed during the lumbar tap test and subsequent gait test performance in the patient population (Pearson coefficient r = 0.049-0.129). Log normalization of the volume of CSF removed and controlling for age and sex failed to yield a significant relationship. Subgroup analyses focusing on patients who showed greater than 20% improvement in any of the gait end points or who were deemed sufficiently responsive clinically to warrant surgery also yielded no significant relationships between the volume of CSF removed and gait outcomes, but there were preliminary findings that patients who underwent tap with larger-gauge needles had better postprocedure ambulation among patients who showed greater than 20% improvement in immediate time score ( P = .04, n = 62). We found no evidence to support that a higher volume of CSF removal impacts gait testing, suggesting that a high volume of CSF removal may not be necessary in a diagnostic lumbar tap test. © 2017 by American Journal of Neuroradiology.

    Adult scoliosis is a condition in which the spinal deformity occurs because of degeneration. Although various studies have agreed on the importance of restoring the sagittal balance, few have evaluated the relationship between functional scores and radiological parameters. The primary objective of this retrospective study was to demonstrate the correlation between radiographic parameters and functional outcomes in adult patients with lumbar or thoracolumbar degenerative scoliosis. The secondary objective was to assess the long-term effects of posterolateral fusion for treating this deformity. This single-centre retrospective study included 47 patients over 50years of age who had degenerative lumbar scoliosis treated with an instrumented posterolateral fusion; the mean follow-up was 6.4years (range 2 to 20). Radiographic analysis of A/P and lateral full spine standing radiographs was carried out with the KEOPS software. Three pelvic parameters (pelvic tilt, pelvic incidence, sacral slope), two spinal parameters (lumbar lordosis and thoracic kyphosis) and three sagittal balance parameters (C7 sagittal tilt, C7 Barrey's ratio and spinosacral angle) were calculated. The functional outcomes were evaluated through three self-assessment questionnaires: Oswestry Disability Index, SRS-30 and SF-36. The correlation between clinical and radiographic parameters was calculated with Spearman's correlation test. There was a significant correlation between the SF-36 (PCS) and the following three sagittal parameters: sacral slope (r=-0.31453; P=0.04), lumbar lordosis (r=-0.30198; P=0.0491) and spinosacral angle (r=-0.311967; P=0.0366). The mean ODI score was 33.61, which corresponds to minimal to moderate disability. The mean physical (PCS) and mental (MCS) component summary scores of the SF-36 were 37.70 and 38.40, respectively. The mean SRS-30 score was 3.07. It is essential that the sagittal balance be restored when treating degenerative lumbar scoliosis to generate better

    In this study, we are using a recently developed method: a minimally invasive retractor system and an operating microscope to treat far lateral lumbar herniated disc. This method decreases tissue dissection and blood loss, and improves postoperative recovery. This is a retrospective study of 46 patients, there was 25 female and 21 male. They all underwent minimal invasive surgery. The average age was 56 years old (19-83 years). Lumbar disc herniation is a common pathology. Far lateral disc herniation accounts for 2.6% to 11.2% of all lumbar disc herniation. A few surgical techniques have been describes to treat this type of disc pathology. All patients were operated under general anesthesia. The fluoroscopic guidance was absolutely necessary. A 12-15 mm skin incision was made on the side of the disc herniation (30 mm from the midline). Then, we inserted a tubular retractor system (muscle splitting approach) followed by a 14 mm diameter-working channel. Under operating microscope the pars interarticularis was dreamed to expose the nerve root and the disc. After removing the intertransverse ligament, we removed the herniated disc. The average time of surgery was 55 min. The operating time decreased with the experience of the surgical team. Postoperatively the radicular pain was around 2 (using an analogical visual scale), over 7 preoperatively. The length of hospitalization was 3 days. There were no complications in our study. The average follow-up was 2 years (6-36 months). There was no complication, no postoperative infection. This technique combines the advantages of endoscopic surgery and microscope guided surgery (3D vision) and provides good functional results in this study.

    Objective: To discuss the indications, long-term outcomes and complications of microendoscopy discectomy (MED) and percutaneous lumbar discectomy (PLD) in treating central lumbar intervertebral disc herniation, and to compare the advantages of the two procedures. Methods: During the period from Jan. 2001 to March 2002 surgical procedure was carried out in sixty-three patients with single central lumbar disc herniation. The surgeries included MED (n=23) and PLD (n=40). The clinical data were retrospectively analyzed. The lesion site, the operation time, the blood loss in operation, the time staying in bed, the hospitalization cost and the postoperative hospitalization days were recorded. Oswestry disability index (ODI) and MacNab score were determined. Statistical analysis was performed by using pair sample t-test, κ-test and Fisher exact test. All patients were followed up. Results: A mean follow-up time was (5.1±0.6) years for patients receiving MED and (6.6±0.7) years for patients receiving PLD. The ODI and MacNab scores of patients receiving MED were better than these of patients receiving PLD. The hospitalization cost and the postoperative hospitalization days of MED group was higher and longer than these of PLD group, the differences between the two groups were statistically significant. The occurrence of long-term complication in MED group was 3.49%, while no complication was seen in PLD group. Conclusion: For the treatment of central lumbar intervertebral disc herniation, both MED and PLD are safe and minimally-invasive procedures with satisfactory long-term effectiveness, and the patients recover from clinical symptoms quickly. The PLD has used more common than MED. The performance of MED needs more skill and experience. Therefore, an interventional radiologist has to follow a relatively long learning curve in order to get the sufficient training and practice before he or she can master the technique of MED with full confidence. However, the long

    To investigate the distribution and characteristics of the lumbar intervertebral disc height (IDH) in asymptomatic Asian population and to determine whether the lumbar IDH is related to the lumbar spine sagittal alignment. A cohort of 169 cases of asymptomatic volunteers was enrolled from January 2014 to July 2016. All participants underwent magnetic resonance imaging of the lumbar spine and panoramic radiography of the spine. Panoramic radiographs of the spine were taken to evaluate pelvic incidence (PI), sacral slope (SS), and pelvic tilt (PT) using Surgimap® software. Roussouly classification was utilized to categorize all subjects according to the four subtypes of sagittal alignment. The IDH was measured on the MRI mid-saggital section of the vertebral body. The relationships between lumbar IDH and spine-pelvic parameters were also assessed using the Spearman correlation analysis. The reference value ranges of IDH in asymptomatic Asian volunteers between L1/2, L2/3, L3/4, L4/5, and L5/S1 were (6.25, 10.99), (6.97, 12.08), (7.42, 13.3), (7.76, 14.57),and (7.11, 13.12) mm, respectively. Based on the above reference value, the high lumbar intervertebral space is defined as more than 14 mm. According to the Roussouly Classification, there are 33 cases in type I, 48 in type II, 66 in type III, and 22 in type IV. According to the definition of the high IDH, there are two cases in type I, three in type II, nine in type III, and eight in type IV. The results indicated that people in the Roussouly III and IV subtypes had greater values for IDH compared to those of Roussouly I and II subtypes, and the spinopelvic parameters were partly correlated with IDH in different subtypes. In addition, levels L4-L5 showed the highest IDH for all four groups followed by the L3-L4 and L5-S1 levels, and the value of L3-L4 is equivalent to that of L5-S1. All type groups showed moderate and positive correlations between the PI and IDH except the level of L1-L2 in type IV. The IDH may

    Several risk factors and causes of adjacent segment disease have been debated; however, no quantitative relationship to spino-pelvic parameters has been established so far. A retrospective case-control study was carried out to investigate spino-pelvic alignment in patients with adjacent segment disease compared to a control group. 45 patients (ASDis) were identified that underwent revision surgery for adjacent segment disease after on average 49 months (7-125), 39 patients were selected as control group (CTRL) similar in the distribution of the matching variables, such as age, gender, preoperative degenerative changes, and numbers of segments fused with a mean follow-up of 84 months (61-142) (total n = 84). Several radiographic parameters were measured on pre- and postoperative radiographs, including lumbar lordosis measured (LL), sacral slope, pelvic incidence (PI), and tilt. Significant differences between ASDis and CTRL groups on preoperative radiographs were seen for PI (60.9 ± 10.0° vs. 51.7 ± 10.4°, p = 0.001) and LL (48.1 ± 12.5° vs. 53.8 ± 10.8°, p = 0.012). Pelvic incidence was put into relation to lumbar lordosis by calculating the difference between pelvic incidence and lumbar lordosis (∆PILL = PI-LL, ASDis 12.5 ± 16.7° vs. CTRL 3.4 ± 12.1°, p = 0.001). A cutoff value of 9.8° was determined by logistic regression and ROC analysis and patients classified into a type A (∆PILL adjacent segment disease, whereas 78.3 % of patients classified as type B alignment had revision surgery. Classification of patients into type A and B alignments yields a sensitivity for predicting adjacent segment disease of 71 %, a specificity of 81 % and an odds ratio of 10.6. In degenerative disease of the lumbar spine a high pelvic incidence with diminished lumbar lordosis seems to predispose to adjacent segment disease. Patients with such pelvic incidence-lumbar lordosis mismatch exhibit a 10-times higher risk for undergoing revision surgery than controls if

    Full Text Available Background. In lumbar disc herniation, most authors recommend nonoperative treatment for the first few weeks of presentation, but what about the upper limit of this golden period? The aim of this study is to assess the effect of preoperative sciatica duration on surgical outcome of lumbar disc herniation. Methods. We retrospectively evaluated 240 patients (124 males and 116 females with a mean age of 36.4±5.9 years (range 16 to 63 surgically treated due to primary stable L4-L5 disc herniation. The patients were placed into two groups: with more and less than 12-month duration of preoperative sciatalgia. Disability and pain were measured by Oswestry Disability Index (ODI and Visual Analogue Scale (VAS. Wilcoxon test and Mann-Whitney U test were used for statistical analysis. Results. Total mean duration of preoperative sciatalgia and follow-up period were 13.3 months (range 2 to 65 and 33.7±5.1 months (range 24 to 72, respectively. Comparison between the groups showed that duration of preoperative sciatalgia either less or more than 12 months did not affect the surgical outcomes significantly. Conclusions. More or less than 12-month duration of preoperative sciatalgia may not affect the surgical outcomes of simple lumbar disc herniation in the patients undergoing discectomy.

    The aim of this study is to compare the clinical, radiological and functional outcome of anterior versus posterior surgical debridement and fixation in patients with thoracic and lumbar tuberculous spondylodiscitis. A total number of 42 patients with tuberculous spondylodiscitis of the thoracic and lumbar spine treated surgically were included in this study. Twenty patients (group A) underwent anterior debridement, decompression and instrumentation by anterior approach. Twenty-two patients (group B) were operated by posterolateral (extracavitary) decompression and posterior instrumentation. Operative parameters, clinical, radiographic and functional results for the two groups were analyzed and compared. The average follow-up period was 15 months (range 12-24) in both groups. The average operative time, blood loss and blood transfusion of anterior group were significantly less than the posterior one. There was significant better back pain relief, kyphotic angle correction and less angle loss in the posterior group than anterior. There was no significant difference between the two groups regarding neurological recovery, functional outcome and fusion rate. Both anterolateral and posterolateral approaches are sufficient for achieving the goals of surgical treatment of thoracic and lumbar Pott's disease but posterolateral approach allows significant better kyphotic angle correction, less angle loss, better improvement in back pain but unfortunately more operative time and blood loss.

  19. Bilateral post-injection fibrosis of the gluteal region mimicking lumbar disc herniation: a case report

    Full Text Available Tissue fibrosis is a known complication of intramuscular injections, which is especially seen in children due to vaccinations and injections. Herein we report a case of post injection gluteal fibrosis that had undergone two unsuccessful lumbar discectomies to treat the symptoms of this disease. A 45 years old male patient was consulted to our clinic from the department of neurochirurgy with complaints of bilateral hip pain. The patient was operated on for lumbar disc herniation in L4-5 level twice but his complaints had not resolved. A third operation including L4-5 instrumentation and fusion was planned. His examination revealed nodules in his both hips. His x-rays, MRI and blood tests were normal. He underwent bilateral gluteal fascia excision and his complaints resolved totally. The clinical diagnosis of post-injection fibrosis is problematic, due to the difficulty of determining the etiology. In many patients the diagnosis comes from a history of injection. Pain in the gluteal region is not a frequently described clinical feature of this condition. Many reports in the literature emphasize a contracture rather than pain. Post-injection fibrosis in the gluteal region may mimic lumbar disc herniation and a detailed physical examination is the key for correct differential diagnosis. In refractory cases not responding to conservative treatment, surgical excision of the nodules may lead to a complete clinical recovery of the patient.

    Purpose. The purpose of this study was to evaluate the effectiveness of a new pedicle screw-based posterior dynamic stabilization device PDS Percudyn System Trade-Mark-Sign Anchor and Stabilizer (Interventional Spine Inc., Irvine, CA) as alternative minimally invasive treatment for patients with lumbar spine stenosis. Methods. Twenty-four consecutive patients (8 women, 16 men; mean age 61.8 yr) with lumbar spinal stenosis underwent implantation of the minimally invasive pedicle screw-based device for posterior dynamic stabilization. Inclusion criteria were lumbar stenosis without signs of instability, resistant to conservative treatment, and eligible to traditional surgical posterior decompression. Results. Twenty patients (83 %) progressively improved during the 1-year follow-up. Four (17 %) patients did not show any improvement and opted for surgical posterior decompression. For both responder and nonresponder patients, no device-related complications were reported. Conclusions. Minimally invasive PDS Percudyn System Trade-Mark-Sign has effectively improved the clinical setting of 83 % of highly selected patients treated, delaying the need for traditional surgical therapy.

  1. Digitalized design of extraforaminal lumbar interbody fusion: a computer-based simulation and cadaveric study.

    Mingjie Yang

    Full Text Available PURPOSE: This study aims to investigate the feasibility of a novel lumbar approach named extraforaminal lumbar interbody fusion (ELIF, a newly emerging minimally invasive technique for treating degenerative lumbar disorders, using a digitalized simulation and a cadaveric study. METHODS: The ELIF surgical procedure was simulated using the Mimics surgical simulator and included dissection of the superior articular process, dilation of the vertebral foramen, and placement of pedicle screws and a cage. ELIF anatomical measures were documented using a digitalized technique and subsequently validated on fresh cadavers. RESULTS: The use of the Mimics allowed for the vivid simulation of ELIF surgical procedures, while the cadaveric study proved the feasibility of this novel approach. ELIF had a relatively lateral access approach that was located 8-9 cm lateral to the median line with an access depth of approximately 9 cm through the intermuscular space. Dissection of the superior articular processes could fully expose the target intervertebral discs and facilitate a more inclined placement of the pedicle screws and cage with robust enhancement. CONCLUSIONS: According to the computer-based simulation and cadaveric study, it is feasible to perform ELIF. Further research including biomechanical study is needed to prove ELIF has a superior ability to preserve the posterior tension bands of the spinal column, with similar effects on spinal decompression, fixation, and fusion, and if it can enhance post-fusion spinal stability and expedites postoperative recovery.

    The purpose of this study was to evaluate the efficacy and safety of percutaneous vertebroplasty for patients with symptomatic osteoporotic vertebral compression fractures adjacent to lumbar instrumented circumferential fusion. Between January 2005 and June 2010, eighteen patients in the authors' institution with lumbar instrumented circumferential fusion had adjacent symptomatic osteoporotic vertebral compression fractures. The patients received percutaneous vertebroplasty using polymethylmethacrylate bone cement augmentation. Radiographs and magnetic resonance imaging were used. The visual analog pain scale and modified Brodsky's criteria were used to compare clinical outcomes pre- and postoperatively. Minimum follow-up was 18 months. Dual-energy x-ray absorptiometry scan confirmed osteoporosis in all patients. The average interval between fusion surgery and sustaining osteoporotic vertebral compression fractures was 24.8 months. The average interval between sustaining osteoporotic vertebral compression fractures and undergoing percutaneous vertebroplasty was 49.3 days. One-level percutaneous vertebroplasty was performed in 13 patients, and 2 levels were performed in 5 patients. The patients' visual analog pain scale scores improved by an average of 53 points postoperatively. Fifteen patients returned to preinjury activities of daily living. The average restoration of the fractured vertebral body height was 12.1%. No major surgery-related complications, occurred except asymptomatic cement leakage in 3 patients. Elderly patients undergoing lumbar instrumented fusion surgery should be aware of the possibility of adjacent vertebral compression fractures. Percutaneous vertebroplasty is a minimally invasive and effective procedure to treat such adjacent segment disease. Copyright 2012, SLACK Incorporated.

    Full Text Available OBJECTIVE: Aim of this study is to assess and compare the outcomes of posterior lumbar interbody fusion (PLIF and posterolateral fusion (PLF in adult isthmic spondylosthesis. BACKGROUND: Posterolateral fusion has been considered the best method and widely been used for surgical treatment of adult spondylolisthesis.Superior results have subsequently been reported with interbody fusion with cages and posterior instrumentation MATERIALS AND METHODS: Thirty six patients with isthmic spondylolisthesis were operated. One group (20 patients had decompression and posterolateral fusion (PLF with a pedicle screw system; other group (16 patients was treated by decompression, posterior lumbar interbody fusion (PLIF and a Pedicle screw system. In both groups adequate decompression was done RESULTS: Seventy seven percent of the patients had a good result with (PLIF and 68 percent with posterolateral fusion (PLF. However there was no statistical difference in cases with low grade slipping, whereas the difference was significant for cases with high grade slipping. Fusion rate was 93% with (PLIF and 68% with (PLF, but without any significant incidence in the functional outcome. 78% has relief of sciatica and neurogenic claudication. CONCLUSION: Based on these findings we found that for high grade spondylolisthesis which requires reduction or if the disc space is still high posterior lumbar inter body fusion is preferable. For low grade spondylolisthesis or if the disc space is narrow posterolateral fusion is preferable. A successful result of fusion operation depends on adequate decompression which relieves radicular symptoms.

    Full Text Available This paper reviews the current published data regarding open transforaminal lumbar interbody fusion (TLIF in relation to minimally invasive transforaminal lumbar interbody fusion (MI-TLIF. Introduction. MI-TLIF, a modern method for lumbar interbody arthrodesis, has allowed for a minimally invasive method to treat degenerative spinal pathologies. Currently, there is limited literature that compares TLIF directly to MI-TLIF. Thus, we seek to discuss the current literature on these techniques. Methods. Using a PubMed search, we reviewed recent publications of open and MI-TLIF, dating from 2002 to 2012. We discussed these studies and their findings in this paper, focusing on patient-reported outcomes as well as complications. Results. Data found in 14 articles of the literature was analyzed. Using these reports, we found mean follow-up was 20 months. The mean patient study size was 52. Seven of the articles directly compared outcomes of open TLIF with MI-TLIF, such as mean duration of surgery, length of post-operative stay, blood loss, and complications. Conclusion. Although high-class data comparing these two techniques is lacking, the current evidence supports MI-TLIF with outcomes comparable to that of the traditional, open technique. Further prospective, randomized studies will help to further our understanding of this minimally invasive technique.

    Full Text Available Background. The relationship between underweight and lumbar spine surgery is still unknown. Aim. To evaluate the effect of underweight versus obesity based on surgical outcome of lumbar disc herniation. Material and Method. In this retrospective study, we evaluated 206 patients (112 male and 94 female with a mean age of 37.5±3.1 years old (ranged 20–72 who have been surgically treated due to the refractory simple primary L4-L5 disc herniation. We followed them up for a mean period of 42.4±7.2 months (ranged 24–57. We used Body Mass Index (BMI, Oswestry Disability Index (ODI, and Visual Analogue Scale (VAS for categorization, disability, and pain assessment, respectively. We used Wilcoxon and Mann-Whitney U tests for statistics. Results. Surgical discectomy in all weight groups was associated with significant improvement in pain and disability, but intergroup comparison showed these improvements in both underweight and obese groups and they were significantly lower than in normal weight group. Excellent and good satisfaction rate was also somewhat lower in both these ends of weight spectrum, but statistically insignificant. Conclusion. Both obesity and underweight may have adverse prognostic influences on the surgical outcome of lumbar disc herniation, although their impact on subjective satisfaction rate seems to be insignificant.

    Multiple osseous loose bodies in the lumbar spine have never been reported. We describe a rare surgical case of multiple osseous loose bodies associated with lumbar isthmic spondylolisthesis. A 74-year-old man who experienced left foot numbness and bilateral gluteal pain was diagnosed with lumbar spondylolisthesis 7 years previously and managed conservatively. He reported recurrence of the left foot numbness 6 months previously, at which time aggressive (rather than conservative) therapy became a consideration. Radiographs of the lumbar spine revealed L5 isthmic spondylolisthesis with dynamic instability at L5/S1. Magnetic resonance imaging of the lumbar spine revealed multiple mass lesions dorsally located in the lumbar canal. Computed tomography myelography demonstrated multiple osseous materials near the isthmic portion at the L5 level where compression of the dural sac by the lesions induced lumbar canal stenosis. The patient underwent posterior decompression surgery that enabled total removal of the osseous lesions. Intraoperative findings revealed osseous lesions located in the fibrocartilage material and no connection of the lytic portion at the L5 level or ligamentum flavum. Postoperative course of the patient was uneventful as his neurological symptoms improved. We described the first instance of multiple loose bodies in the spinal canal with lumbar canal stenosis. It is presumed that long standing minor trauma due to dynamic instability with a trend of hyperossification induced secondary synovial osteochondromatosis forming multiple loose bodies.

    A case report is presented. To describe a rare, previously undescribed pattern of spinal injury. This seems to be a unique injury with no previously described injuries matching the fracture pattern observed. This is a case report based on the experience of the authors. The discussion includes a short literature review based on pubmed searches. We report the case of a 26-year-old female cyclist involved in a road traffic accident with a truck resulting in complete disruption of the lumbar spine. The cyclist was caught on the inside of a truck turning left and seems to have passed under the rear wheels. She was brought to the local emergency department where, after appropriate resuscitation, trauma survey revealed spinal deformity with complete neurologic deficit below T12 and fractured pubic rami, soft tissue injuries to the perineum and multiple abrasions. Plain radiology showed a segmental fracture dislocation of her lumbar vertebrae, extending from the L1 superior endplate through to L4-L5 disc space. The entire segment was displaced in both anteroposterior and lateral planes. Computed tomography confirmed these injuries and ruled out significant visceral injury. She was transferred to the national spinal unit (author unit), where she underwent reduction and fixation with rods and screws from T9-S1, using one cross-link. After her immediate postoperative recovery, she was referred to the national rehabilitation unit. Although so-called "en bloc" lumbar fractures have been previously described, the authors were unable to find any injury of this degree in the literature. This rare injury seems to show a pattern of spinal injury previously undescribed.

    Opacification of collateral pathways other than the central channels is very rare in lumbar epidural venography. Two cases of opacification of the inferior mesenteric vein following extravasation of contrast medium at the tip of the lateral sacral vein catheter are reported. One case is presented in which filling of normal parametrial venous plexuses and the left ovarian vein occurred as a consequence of incompetent or absent valves in the internal iliac vein. The literature containing comparable collateral flow patterns in disease is reviewed. The significance of the phlebographic features in our cases is discussed. (orig.)

    To demonstrate the surgical technique and advantages of the mini-open transforaminal approach for lumbar interbody fusion (TLIF) combined with transpedicular screw fixation. Clinical and radiographic results were assessed to determine the clinical outcomes in twelve consecutive patients selected for minimally invasive access (mini-open technique) for TLIF in Prasat Neurological Institute. A retrospective analysis was performed on 12 patients (age range, 38-74 yr; mean, 54. 8 yr) who underwent mini-open transforaminal approach for lumbar interbody fusion (TLIF) combined with transpedicular screw fixation between September 2006 and June 2008. The titanium pedicle screws were introduced bilaterally through the 3.5 cm length, skin incisions with Spine Classics MLD- system retractor, autologous bone graft were inserted to perform TLIF in all patients. Eight patients were augmented anterior column support with titanium interbody cage, unilateral cage insertion in four patients and the others were inserted bilaterally interbody cages. Six patients presented with low back pain and associated radiculopathy, and six presented with low back pain only. Transforaminal lumbar interbody fusion was performed at L3-L4 in two patients, L4-L5 in four patients, L5-S1 in five patients, and two levels fusion in one patient. All patients were able to ambulate after spinal fusion. The patients were able to walk within 1.4 days (range 1-2 days). The hospital stay averaged 4.4 days (range 3-7 days). Periodic follow-up took place 1 to 21 months after surgery (mean, 7.4 months). The radiological fusion was archived in all nine patients who were operated on more than two months age. The other three patients who had been follow-up less than two months were probably fusion on the 1-month followed-up radiological examination. The use of mini-open technique for pedicle screw instrumentation with spinal fusion procedure provides excellent clinical results and may be an operation of choice for

    The lateral lumbar interbody fusion approach (LLIF), which encompasses the extreme lateral interbody fusion or direct lateral interbody fusion techniques, has gained popularity as an alternative to traditional posterior approaches. With rapidly expanding applications, this minimally invasive surgery (MIS) approach is now utilized in basic degenerative pathologies as well as complex lumbar degenerative deformities and tumors. Given the intimate relationship of the psoas muscle, and hence the lumbar plexus, to this MIS approach, several authors have examined the surgical anatomy of this approach. Understanding this regional neural anatomy is imperative given the potential for serious injuries to both the motor and sensory nerves of the lumbar plexus. In this review, we critically and comprehensively discuss all published studies detailing the surgical anatomy of the lateral lumbar approach with respect to the MIS LLIF techniques. This is a timely review given the rapidly growing number of surgeons utilizing this technique. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Musculoskeletal simulations of lumbar spine loading rely on a geometrical representation of the anatomy. However, this data has an inherent inaccuracy. This study evaluates the in uence of dened geometrical parameters on lumbar spine loading utilizing ve parametrized musculoskeletal lumbar spine...... models for four different postures. The in uence of the dimensions of vertebral body, disc, posterior parts of the vertebrae as well as the curvature of the lumbar spine were studied. Additionally, simulations with combinations of selected parameters were conducted. Changes in L4/L5 resultant joint force...... were used as outcome variable. Variations of the vertebral body height, disc height, transverse process width and the curvature of the lumbar spine were the most in uential. The results indicated that measuring these parameters from X-rays would be most important to morph an existing musculoskeletal...

    A retrospective survey using privacy-conscious questionnaires. To determine the quality and frequency of sexual activities in patients with lumbar disc herniation before and after surgery. Patients and health care professionals often hesitate to talk about the effects of disease, illness, or surgery on sexuality, but it is imperative that sexuality issues be addressed. Of 90 consecutive patients, 64 who had surgically-treated lumbar disc herniation participated in this survey after informed consent. There were 43 males and 21 females with mean age of 36 years. Duration of symptom was averaged 42 weeks. The patients were asked to complete questionnaires concerning sexual desire, activity, adjustment, and satisfaction. About 83% of the patients had sexual desire, and 89% achieved satisfaction during sexual activities in presick period. Lumbar disc herniation decreased sexual desire in 50% and frequency of sexual activity in 59% of the patients. About 67% of males and 81% of females felt discomfort during sexual activity; satisfaction decreased in 28% of male and 41% of females. Adjustment in sexual position was required in 54% of males and 86% of females. Surgery improved sexual desire, frequency of sexual activity, and satisfaction in 85%, 88%, and 94%, respectively. However, 31% of females did not regain sexual desire and 46% still felt discomfort during sexual activity (the rates were 7% and 17% in males, respectively). Sexual activity was resumed within 2 postoperative weeks in 23% (27% in males and 14% in females), and 4 weeks in 53%. Males resumed sexual activity earlier than females. Lumbar disc herniation largely impacted sexual desire, activity, and satisfaction. Adjustment in sexual position was required in large number of patients to avoid discomfort during sexual activities. Surgical treatment improved quality of sexual activities, but more females did not regain sexual desire, felt sexual discomfort, and thereby resumed sexual activities later than males

    Full Text Available   Background: Literature recommends that refractory cases with lumbar disc herniation and appropriate indications are better to be treated surgically, but do all the patients throughout the world consent to the surgery with a same disability and pain threshold? We aim to elucidate the prevalence and severity of disabilities and pain in Iranian patients with lumbar disc herniation who have consented to the surgery.   Methods: In this case series study, we clinically evaluated 194 (81 female and 113 male admitted patients with primary, simple, and stable L4-L5 or L5-S1 lumbar disc herniation who were undergoing surgical discectomy. The mean age of the patients was 38.3±11.2 (range: 18-76 years old. Disabilities were evaluated by the items of the Oswestry Disability Index (ODI questionnaire and severity of pain by the Visual Analogue Scale (VAS. Chi-square test was used to compare the qualitative variables. Results: Severe disability (39.2% and crippled (29.9% were the two most common types of disabilities. Mean ODI score was 56.7±21.1 (range: 16-92. Total mean VAS in all patients was 6.1±1.9 (range: 0-10. Sex and level of disc herniation had no statistical effect on preoperative ODI and VAS. The scale of six was the most frequent scale of preoperative VAS in our patients. Conclusion: Iranian patients with lumbar disc herniation who consented to surgery have relatively severe pain or disability. These severities in pain or disabilities have no correlation with sex or level of disc herniation and are not equal with developed countries.

    Decompression and fusion is considered as the 'gold standard' for the treatment of degenerative lumbar diseases, however, many disadvantages have been reported in several studies, recently like donor site pain, pseudoarthrosis, nonunion, screw loosening, instrumentation failure, infection, adjacent segment disease (ASDis) and degeneration. Dynamic neutralization system (Dynesys) avoids many of these disadvantages. This system is made up of pedicle screws, polyethylene terephthalate cords, and polycarbonate urethane spacers to stabilize the functional spinal unit and preserve the adjacent motion after surgeries. This was a retrospective cohort study to compare the effect of Dynesys for treating degenerative lumbar diseases with posterior lumbar interbody fusion (PLIF) based on short term followup. Seventy five consecutive patients of lumbar degenerative disease operated between October 2010 and November 2012 were studied with a minimum followup of 2 years. Patients were divided into two groups according to the different surgeries. 30 patients underwent decompression and implantation of Dynesys in two levels (n = 29) or three levels (n = 1) and 45 patients underwent PLIF in two levels (n = 39) or three levels (n = 6). Clinical and radiographic outcomes between two groups were reviewed. Thirty patients (male:17, female:13) with a mean age of 55.96 ± 7.68 years were included in Dynesys group and the PLIF group included 45 patients (male:21, female:24) with a mean age of 54.69 ± 3.26 years. The average followup in Dynesys group and PLIF group was 2.22 ± 0.43 year (range 2-3.5 year) and 2.17 ± 0.76 year (range 2-3 year), respectively. Dynesys group showed a shorter operation time (141.06 ± 11.36 min vs. 176.98 ± 6.72 min, P degenerative disease showed clinical benefits with motion preservation of the operated segments, but does not have the significant advantage on motion preservation at adjacent segments, to avoid the degeneration of adjacent intervertebral disk.

    Lumbar interbody fusion is currently the gold standard in treating patients with disc degeneration or segmental instability. Despite it having been used for several decades, the non-union rate remains high. A failed fusion is frequently attributed to an inadequate mechanical environment after instrumentation. Finite element (FE) models can provide insights into the mechanics of the fusion process. Previous fusion simulations using FE models showed that the geometries and material of the cage can greatly influence the fusion outcome. However, these studies used axisymmetric models which lacked realistic spinal geometries. Therefore, different modeling approaches were evaluated to understand the bone-formation process. Three FE models of the lumbar motion segment (L4-L5) were developed: 2D, Sym-3D and Nonsym-3D. The fusion process based on existing mechano-regulation algorithms using the FE simulations to evaluate the mechanical environment was then integrated into these models. In addition, the influence of different lordotic angles (5, 10 and 15°) was investigated. The volume of newly formed bone, the axial stiffness of the whole segment and bone distribution inside and surrounding the cage were evaluated. In contrast to the Nonsym-3D, the 2D and Sym-3D models predicted excessive bone formation prior to bridging (peak values with 36 and 9% higher than in equilibrium, respectively). The 3D models predicted a more uniform bone distribution compared to the 2D model. The current results demonstrate the crucial role of the realistic 3D geometry of the lumbar motion segment in predicting bone formation after lumbar spinal fusion. Copyright © 2018 Elsevier Ltd.

    Controlled laboratory study, repeated-measures design. Diminished multifidus activation and cross-sectional area are frequent findings in persons with low back pain. Increasing lumbar lordosis has been shown to increase activation of the multifidus with a minimal increase in activation of the long global extensors during unsupported sitting. To examine the influence of postural cueing to increase lumbar lordosis on lumbar extensor activation during trunk stabilization exercises. Thirteen asymptomatic participants (9 male, 4 female) were instructed to perform 6 trunk stabilization exercises using a neutral position and increasing lumbar lordosis. Electrical activity of the deep multifidus and longissimus thoracis was recorded using fine-wire intramuscular electrodes. The mean root-mean-square of the electromyography (EMG) signal obtained during each exercise was normalized to a maximum voluntary isometric contraction (MVIC). A 2-way, repeated-measures analysis of variance (posture by exercise) was performed for each muscle. When averaged across the 6 exercises, postural cueing to increase lumbar lordosis resulted in greater multifidus EMG activity compared to performing the exercises in a neutral posture (35.3% ± 15.1% versus 29.5% ± 11.2% MVIC). No significant increase in longissimus thoracis EMG activity was observed when exercising with cueing to increase lumbar lordosis. This study suggests that postural cueing to increase lumbar lordosis during trunk stabilization exercises may better promote multifidus activation than traditional stabilization exercises alone. Future studies are needed to determine whether increasing lumbar lordosis improves multifidus activation in persons with low back pain.

    Various lumbar exercise programs are prescribed for rehabilitation purposes following microdiscectomy applied for the treatment of lumbar disk herniation. The literature contains several studies on this subject. However, there are no studies investigating the effects of supervised dynamic lumbar stabilization exercises on fear and fear/regression attitudes of patients and on their return to work. This study investigates the effects of supervised dynamic lumbar stabilization exercises during postoperative rehabilitation on spinal mobility, pain, functional status, return to work, quality of life, and fear/regression attitude of patients who underwent lumbar microdiscectomy for the first time. The study was conducted at physical therapy and rehabilitation clinics. A randomized clinical trial comparing exercise programs after lumbar microdiscectomy. Forty-four lumbar microdiscectomy patients were randomized into two groups. Each group was assessed in terms of low back pain, leg pain, spinal mobility, Oswestry Disability Index (ODI), and Nottingham Health Profile (NHP), at the postoperative first, second, and sixth months. Fear/regression beliefs and level of pain were evaluated through the Fear Avoidance Belief Questionnaire (FABQ). Forty-four patients were randomly divided into two equal groups of 22 subjects, respectively, as a study group with Dynamic Lumbar Stabilization (DLS) exercises and home exercises, and a control group with only home exercises for a period of four weeks. Leg pain decreased more in the study group compared with the control group (P=0.004). Spinal mobility scores demonstrated greater increases in the study group (Pwork periods.

    Retrospective analysis. The object is to assess the correlation between whole lumbar lordosis (LL) and the segmental angle (SA) after single-level anterior lumbar interbody fusion for degenerative lumbar spondylolisthesis. The restoration of the SA at lower lumbar spine is meaningful, considering it contributes approximately 60% of LL, and revision surgery due to flat back or adjacent segment pathology was necessary decades after the initial surgery. However, little is known about the change of whole lumbar curvature after single-level lower lumbar fusion surgery, especially for balanced spine. We included 41 consecutive patients (M:F=9:32; mean age, 59.8±9.3 y) with a single-level anterior lumbar interbody fusion surgery for low-grade degenerative spinal spondylolisthesis, with C7 plumb line of <5 cm and ≥2-year follow-up period. The operated levels were L4-L5 in 34 patients and L5-S1 in 7 patients. Whole LL, SA, pelvic tilt, and sacral slope were compared. According to the Macnab criteria, a favorable outcome (excellent, 21; good, 15) was achieved in 36/41 (88%; excellent, 21; good, 15) patients. LL and SA were significantly changed from -50.8±9.9 to -54.6±11.1 degrees and -15.6±6.1 to -18.7±5.1 degrees (P<0.01), and a positive correlation (r=0.43, P=0.01) was observed between LL and SA at postoperative month 24. The changes to the pelvic tilt and sacral slope were not significant. Whole lumbar sagittal alignment was influenced by single SA. Therefore, obtaining adequate segmental lordosis is desirable considering the effect on the whole spine for a long time.

    To evaluate the predictive value of Modic typeII changes on nuclear magnetic resonance (NMR) prior to intervention by discectomy for lumbar disc herniation in patients with radicular symptoms. Retrospective descriptive study of 190 patients (58.2% men and 41.8% women) with a mean age of 43.5 years, treated between December 2005 and January 2013. They were divided into group 1, single disc herniation (n=85), and group 2, with disc herniation and changes Modic typeII (n=80). Variables studied: weight, height, handedness, level of injury, previous neurological deficit, postoperative complications, persistent pain and need for posterior lumbar fusion, with a mean of 67 months (group 1: 68.1; group 2: 66.8). In group 1 there were four hernia recurrences requiring revision surgery and six patients needed lumbar fusion. In group 2, four recurrences were also revised and eight cases requiring arthrodesis were observed. No statistically significant differences were found when comparing the occurrence of relapse (P=.903), the need for subsequent fusion (P=.572) or in the remaining variables. The data obtained and the characteristics of our study, we cannot say that Modic typeII changes were a predictive sign of the result of lumbar discectomy in our study population.

    The therapeutic modalities available for the conservative management of chronic cervical and lumbar pain include underwater traction, the usefulness of which is not universally acknowledged. No reports have been published on clinical trials evaluating underwater traction. This study was intended to ascertain any beneficial impact of weightbath therapy on the clinical parameters and quality of life of patients with cervical/lumbar discopathy. The study population comprised 72 subjects. Two groups of 18 patients each received underwater traction therapy of the cervical or lumbar spine with add-on McKenzie exercises and iontophoresis. The remaining two groups, treated with exercises and iontophoresis, served as controls. VAS and SF36 scores, range of motion were monitored to appraise therapeutic efficacy in cervical discopathy, whereas these parameters were supplemented by the Oswestry index in lumbar discopathy. A MRI scan was done at baseline and after 3 months of follow-up. Underwater cervical or lumbar traction therapy for discopathy achieved significant improvement of all study parameters, which was still evident 3 months later. Among the controls, significant improvement of just a single parameter was seen in patients with lumbar, and of two parameters in those with cervical discopathy. Underwater traction therapy effectively mitigates pain, enhances joint flexibility, and improves the quality of life of patients with cervical or lumbar discopathy. The equipment required to administer weightbath therapy is simple to install and treatment technique is straightforward.

    Full Text Available Early diagnosis of meningitis and encephalitis and prompt initiation of appropriate therapy is vital and any delay will lead to high mortality and serious and permanent morbidity. The main purpose of this study was to evaluate the management of 220 patients with suspected central nervous system (CNS infections (meningitis and encephalitis to determine the percentage of patients’ suspected CNS infection undergo lumbar puncture in acceptable time (in accordance with conventional algorithms. In this descriptive study, patients with suspected CNS infections admitted to Bu-Ali and Qods hospitals, in the period July 2013 to December 2015 were studied. Information of 220 patients was collected. Continuous variables were summarized as means ± standard deviation and categorical variables as frequencies and percentages. Lumbar puncture (LP in patients was delayed in 200 cases (91%. Most common causes of delay in performing LP were prolongation of the process of determining patient needs to puncture, satisfying patients, CT scan delay and the delay in allowing LP by neurologist. In this study, delaying LP rate was higher than other studies. It seems certain pattern in assistants’ visits for counseling. CT requests and neurologic consultation before LP performed for all adult patients.

    The lumbar facet disease is a frequently overlooked cause of sciatic pain, but the lumbar facet joints are well-recognized source of low back pain and radiating leg pain which can be confused with sciatica due to herniated disc. We measured the angulation of the facet joints on axial spine CT films in 149 cases which contains 41 normal group and 108 abnormal group and studied the relationship between the angulation and degeneration of the facets, the asymmetry of each sided facets and facet degeneration, the asymmetry and disc protrusion, and the asymmetry and annular bulging of the disc. The results were as follows: 1. Facet angulation in abnormal group were more sagittally oriented than the normal group. 2. The angulation of right facet was more sagittally oriented than the left in L4-5 level of abnormal group. 3. Degeneration of facet joints occur asymmetrically, and the more facet joint degenerates, the more it orients sagittally, particularly in L4-5. 4. Asymmetry in facet joint degeneration and unilateral disc protrusion of L5-SI level is greater than the normal gro0008.

    In order to evaluate the stenotic condition of lumbar spinal canal, MRI was compared with myelogram and with discogram in 82 patients, all of whom underwent surgical exploration. Pathologic conditions were studied including herniated nucleus pulposus in 36, lumbar canal stenosis (central, peripheral portion, combined) in 35, and spondylisthesis (degenerative, spondylolytic, dysplastic) in 11. Correlation between T2 mid-sagittal image of the thecal sac and profile view of full-column myelogram was very high, but fine parts such as adhesive change or redundancy or anomalous condition of nerve roots were more clearly observed on myelogram than on MRI. And some of them were not detected on MRI. The stage of disc degeneration was classified in 5 grades according to signal intensity and irregularity of the disc on T2-weighted image. The evaluation of disc degeneration was similar to discogram. But MRI will not replace discography for identifying the source of pain in symptomatic patients. Although MRI is the most important imaging modality to diagnostic screening and to post-operative evaluation of the stenotic condition, determination of the strict indication and the method of the operation will need myelogram and/or discogram and so on.

    In this paper the authors discuss the clinical problem of lumbar hypermobility. The therapeutical possibilities are resumed briefly. The philosophy of medical training therapy ("Heilgymnastik") is described. More extensive the extra-advantages of hydrotherapy (methodical back-stroke swimming) are searched for in a theoretical deductive way. The authors found that: 1. swimming is a low-impact sport so far as the articulations are concerned, 2. back-stroke is done mainly in a lumbar kyphosis, 3. swimming is also an excellent cardiopulmonary training, 4. when swimming the muscles of the shoulder girdle and pelvic girdle are trained in a nearly isokinetic way (power-endurance), 5. the short transverso-spinal muscles are indirectly trained in their tonic more than phasic stretch reflex (posture function), 6. the muscles of the trunk are trained in a nearly isometric way in the appropriate angles (erect position), 7. the position of the head in the water facilitates the abdominal muscles (tonic neck reflex), 8. the cool temperature of the water generates training-enhancing stress-responses, 9. endurance-training is ideal for the postural function of the lower back muscles (especially the deeper layers near the spine) which are anatomical and physiological suited for this purpose, 10. warming-up and cooling-down procedures prepare the neuromuscular, the cardiovascular and metabolic functions before the workout-session (a cold shower afterwards acts to tonicize the skin and muscles).

  20. Lumbar spondylolysis in the adolescent athlete.

    Lawrence, Kevin J; Elser, Tim; Stromberg, Ryan

    2016-07-01

    Spondylolysis is a common occurrence for adolescent athletes who have low back pain. The injury involves a defect in the pars interarticularis, occurring as a result of repeated hyperextension and rotation. Clinical findings might include tightness of the hip flexors and hamstrings, weakness of the abdominals and gluteals, and an excessive lordotic posture. The validity of several clinical tests were compared alongside magnetic resonance imaging, but were not able to distinguish spondylolysis from other causes of low back pain. Medical referral should be arranged so that medical imaging and diagnostic testing can be completed to insure a proper diagnosis. Initial intervention includes rest from sport, which may vary from 2 weeks to 6 months. Bracing is also used to help minimize lumbar lordosis and lumbar extension. Exercises that focus on stabilization and spine neutral position should be incorporated in physical therapy intervention. Avoiding end ranges is important while performing exercises to minimize the translational and rotational stresses on the spine. Surgical interventions have also been recommended for athletes who have had persistent low back pain for more than six months with no relief from rest and bracing. Copyright © 2016 Elsevier Ltd.

    Spondylodiscitis is an infection of the intervertebral disc and adjacent vertebrae. With the advent of minimally invasive spinal surgery, less invasive approaches have been considered for the treatment of discitis. To date, however, there have been no reported cases of a minimally invasive lateral retroperitoneal transpsoas approach for the treatment of spondylodiscitis. The authors report a case of medically refractory discitis in a patient with multiple comorbidities who underwent a successful limited debridement via a lateral transpsoas corridor. This case describes a minimally invasive approach used to treat a patient with lumbar discitis/osteomyelitis who was otherwise a suboptimal surgical candidate.

  3. Unusual Relapse of Primary Central Nervous System Lymphoma at Site of Lumbar Puncture

    2014-01-01

    Full Text Available Primary CNS lymphoma (PCNSL is a rare non-Hodgkin’s lymphoma confined to the CNS. Local relapse of this disease is common, but extracranial or subcutaneous metastasis is rare with only a few cases being reported in literature. We report a 63-year-old male patient, who responded well to treatment for PCNSL but relapsed two and half years later with a lumbosacral nodule at the site of a previous lumbar puncture due to microscopic tumor seeding. Clinicians treating patients with PCNSL must remain alert to the possibility of extracranial solitary relapse even after the resolution of initial disease because prompt treatment can result in a good outcome.

    In summary a fascinating case is presented in a 54-year-old man who developed a chordoma of the fourth lumbar vertebra which was treated by radiotherapy, with good results. The man remained asymptomatic relatively for several years and then presented with recurrence of back pain and neurological deficits. Plain films, CT and myelography showed considerable destruction of the body of L4 with a sclerotic pattern suggesting the effects of previous radiotherapy.

    To determine the effect of degenerative disease of the lumbar spine on bone mineral density in the lumbar spine and femoral neck. We reviewed radiographs and dual energy x-ray absorptiometry scans of the lumbar spine and hip in 305 Caucasian women with suspected osteoporosis. One hundred and eight-six patient remained after excluding women less than 40 years of age (n=18) and those with hip osteoarthritis, scoliosis, lumbar spine fractures, lumbar spinal instrumentation, hip arthroplasty, metabolic bone disease other than osteoporosis, or medications known to influence bone metabolism (n=101). On the basis of lumbar spine radiographs, those with absent/mild degenerative disease were assigned to the control group and those with moderate/severe degenerative disease to the degenerative group. Spine radiographs were evaluated for degenerative disease by two radiologists working independently; discrepant evaluations were resolved by consensus. Lumbar spine and femoral neck bone mineral density was compared between the two groups. Forty-five (24%) of 186 women were assigned to the degenerative group and 141 (76%) to the control group. IN the degenerative group, mean bone mineral density measured 1.075g/cm? in the spine and 0.788g/cm 2 in the femoral neck, while for controls the corresponding figures were 0.989g/cm 2 and 0.765g/cm 2 . Adjusted for age, weight and height by means of analysis of variance, degenerative disease of the lumbar spine was a significant predictor of increased bone mineral density in the spine (p=0.0001) and femoral neck (p=0.0287). Our results indicate a positive relationship between degenerative disease of the lumbar spine and bone mineral density in the lumbar spine and femoral neck, and suggest that degenerative disease in that region, which leads to an intrinsic increase in bone mineral density in the femoral neck, may be a good negative predictor of osteoporotic hip fractures

    The purpose of this paper is to evaluate and analyze the radiological findings of 13 cases of lumbar spondylolisthesis with intact neural arch at Han-Gang Sung- Shim Hospital during period from Jan. 1975 to June 1980. 1. The age distribution of the patients varied from 31 to 83 years old. The average of the age was 53 years old. 12 patients were female and only one patient was male. 2. All cases revealed anterior slipping of the L4 body on the L5 body, of which degree was classified by Meyerding's method, first degree in 12 patients and second degree in one patient. 3. The angle between the pedicle and inferior articular facet of affected vertebra was measured by Junghann's method. The average of angle was 123 degree. 4. Of 13 cases, 2 cases who had neural compression caused by dislocation of the vertebral bodies and intrusion of lamina and arthritic facets into stenotic spinal canal treated by laminar decompression including foraminotomy. Good results were obtained. 5. The secondary degenerative change of the vertebra was considered to be the cause of the spondylolisthesis with intact neural arch.

    Bibliometric review of the literature. To analyze and quantify the most frequently cited papers in lumbar spine surgery and to measure their impact on the entire lumbar spine literature. Lumbar spine surgery is a dynamic and complex field. Basic science and clinical research remain paramount in understanding and advancing the field. While new literature is published at increasing rates, few studies make long-lasting impacts. The Thomson Reuters Web of Knowledge was searched for citations of all papers relevant to lumbar spine surgery. The number of citations, authorship, year of publication, journal of publication, country of publication, and institution were recorded for each paper. The most cited paper was found to be the classic paper from 1990 by Boden et al that described magnetic resonance imaging findings in individuals without back pain, sciatica, and neurogenic claudication showing that spinal stenosis and herniated discs can be incidentally found when scanning patients. The second most cited study similarly showed that asymptomatic patients who underwent lumbar spine magnetic resonance imaging frequently had lumbar pathology. The third most cited paper was the 2000 publication of Fairbank and Pynsent reviewing the Oswestry Disability Index, the outcome-measure questionnaire most commonly used to evaluate low back pain. The majority of the papers originate in the United States (n=58), and most were published in Spine (n=63). Most papers were published in the 1990s (n=49), and the 3 most common topics were low back pain, biomechanics, and disc degeneration. This report identifies the top 100 papers in lumbar spine surgery and acknowledges those individuals who have contributed the most to the advancement of the study of the lumbar spine and the body of knowledge used to guide evidence-based clinical decision making in lumbar spine surgery today. 3.

    Lumbar interbody fusion is a widely accepted surgical procedure for patients with lumbar degenerative spondylolisthesis and lumbar spinal instability in the active age group. However, in elderly patients, it is often questionable whether it is truly necessary to construct rigid fixation for a short period of time. In recent years, we have been occasionally performing posterior dynamic stabilization in elderly patients with such lumbar disorders. Posterior dynamic stabilization was performed in 12 patients (6 women, 70.9 ± 5.6 years old at the time of operation) with lumbar degenerative spondylolisthesis in whom % slip was less than 20% or instability associated with lumbar disc herniation between March 2011 and March 2013. Movement occurs through the connector linked to the pedicle screw. In practice, 9 pairs of D connector system where the rod moves in the perpendicular direction alone and 8 pairs of Dynamic connector system where the connector linked to the pedicle screw rotates in the sagittal direction were installed. The observation period was 77–479 days, and the mean recovery rate of lumbar Japanese Orthopedic Association (JOA) score was 65.6 ± 20.8%. There was progression of slippage due to slight loosening in a case with lumbar degenerative spondylolisthesis, but this did not lead to exacerbation of the symptoms. Although follow-up was short, there were no symptomatic adjacent vertebral and disc disorders during this period. Posterior dynamic stabilization may diminish the development of adjacent vertebral or disc disorders due to lumbar interbody fusion, especially in elderly patients, and it may be a useful procedure that facilitates decompression and ensures a certain degree of spinal stabilization.

    Background: Instrumented lumbar spine surgery is associated with an increased risk of adjacent segment disease (ASD). Multiple studies have explored the various risk factors contributing to ASD that include; fusion length (especially, three or more levels), sagittal malalignment, facet injury, advanced age, and prior cephalad degenerative disease. Methods: In this selective review of ASD, following predominantly instrumented fusions for lumbar degenerative disease, patients typically underwent open versus minimally invasive surgery (MIS), transforaminal lumbar interbody fusions (TLIFs), posterior lumbar interbody fusions (PLIFs), or rarely posterolateral lumbar instrumented or noninstrumented fusions (posterolateral lumbar fusion). Results: The incidence of ASD, following open or MI lumbar instrumented fusions, ranged up to 30%; notably, the addition of instrumentation in different series did not correlate with improved outcomes. Alternatively, in one series, at 164 postoperative months, noninstrumented lumbar fusions reduced the incidence of ASD to 5.6% versus 18.5% for ASD performed with instrumentation. Of interest, dynamic instrumented/stabilization techniques did not protect patients from ASD. Furthermore, in a series of 513 MIS TLIF, there was a 15.6% incidence of perioperative complications that included; a 5.1% frequency of durotomy and a 2.3% instrumentation failure rate. Conclusions: The incidence of postoperative ASD (up to 30%) is greater following either open or MIS instrumented lumbar fusions (e.g., TLIF/PLIF), while decompressions with noninstrumented fusions led to a much smaller 5.6% risk of ASD. Other findings included: MIS instrumented fusions contributed to higher perioperative complication rates, and dynamic stabilization did not protect against ASD. PMID:26693387

    Background: Spondylolithesis is forward slipping of upper vertebra in relation to its lower one, which at times requires surgery. The objective of present study is to document the outcome of surgical treatment in spondylolisthesis of lumbosacral region. Methods: We reviewed outcome of surgery in 45 patients with spondylolisthesis. Improvement in pain intensity, neurological status and union achieved after surgery was studied. All patients requiring surgical treatment were included in the study. The patients were operated by single spine surgeon. A proforma was made for each patient and records were kept in a custom built Microsoft access database. Results: Majority of our patient were in 4th and 5th decade with some male domination. Pain was main indication for surgery which was excruciating in 6, severe in 33, and moderate in 6 cases. The neurological status was normal in 34 cases while 11 patients had some deficit. L5-S1 was affected in 26, L4-L5 in 13 and multi or high level was found in rest of cases. Slip grade was measured with Meyerding grades, 18 had grade II, 15 had I, 9 had III and 3 had IV spondylolisthesis. Posterior lumbar inter body fusion (PLIF) was done in 24 patients, posterolateral, transforaminal lumbar inter body and anterior inter body fusion in others. Translaminar screw fixation, transpedicular transdiscal transcorporial and Delta fixation in some cases. Pedicle screw fixation was done in most cases, AO fixator internae and 4.5 mm screw in others. Average follow up was 2 years and 5 months, max 5 years and minimum 6 months. Pain relief was achieved in 82%, neurological improvement 60% and union in 91% cases. There was no deterioration of neurological status, two implant failure and one wound infection. Conclusion: Surgical procedure for Spondylolisthesis must be individualised. Young patients with spondylolysis can be treated with osteosynthesis and sparing of motion segment. PLIF provides satisfactory results in majority of low to moderate

    Full Text Available OBJECTIVES: Hydrodiscectomy is a new technique used for percutaneous spinal discectomy that employs a high-intensity stream of water for herniated disc ablation and tissue aspiration. No previous clinical study has examined the effects of percutaneous hydrodiscectomy. The aim of this study is to evaluate the outcomes of hydrodiscectomy compared to open microdiscectomy regarding pain, function, satisfaction, complications and recurrence rates. METHODS: In this randomized clinical trial, patients referred to our tertiary hospital for lumbar back pain were recruited and included in the study if they had disc protrusion or small herniation in only one level, without neurological deficits and with no resolution after six weeks of conservative treatment. One group underwent open microdiscectomy, and the other group underwent percutaneous microdiscectomy via hydrosurgery. Function was evaluated using the Oswestry Disability Index and pain was assessed using a visual analog scale. Evaluations were performed preoperatively, and then during the first week and at one, three, six and twelve months postoperatively. Personal satisfaction was verified. Clinicaltrials.gov: NCT01367860. RESULTS: During the study period, 20 patients were included in each arm and 39 completed one-year of follow-up (one patient died of unrelated causes. Both groups exhibited equal improvement on the visual analog scale and Oswestry evaluations after treatment, without any significant differences. The improvement in the lumbar visual analog scale score was not significant in the hydrodiscectomy group (p=0.138. The rates of infection, pain, recurrence and satisfaction were similar between the two groups. CONCLUSION: Percutaneous hydrodiscectomy was demonstrated to be as effective as open microdiscectomy for reducing pain. The rates of complications and recurrence of herniation were similar between groups. Patient satisfaction with the treatment was also similar between groups.

    There are two modified TLIF, including MIS-TLIF and TLIF through Wiltse approach (W-TLIF). Although both of the two minimally invasive surgical procedures can be effective in the treatment for lumbar degenerative diseases, no comparative analysis has been made so far regarding their clinical outcomes. To compare the clinical outcomes of MIS-TLIF and W-TLIF for the treatment for single-segment degenerative lumbar diseases. Ninety-seven patients with single-segment degenerative lumbar disorders were included in this study. Forty-seven underwent MIS-TLIF surgery (group A). For group B, fifty patients underwent W-TLIF. The Japanese Orthopedic Association (JOA) score, the visual analog scale (VAS) of low back pain (LBP) and leg pain, MRI score and atrophy rate of CSA, interbody fusion rate were assessed during the postoperative follow-up. Incision length, blood loss, operative time, CPK, and postoperative incision pain VAS were better in group A (P degenerative disease. MIS-TLIF has less blood loss, shorter surgical incision, and less lower postoperative back pain, while W-TLIF is less expensive for hospital stay with lower exposure to X-rays.

    Professional basketball players are at risk for lumbar disc herniation (LDH), yet the evidence guiding treatment after operative or nonoperative management of this condition in the National Basketball Association (NBA) is limited. NBA players with LDH will have different performance outcomes based on treatment type. Case-control study. Level 4. Athletes in the NBA with an LDH were identified through team injury reports, transaction records, and public sports archives. A 1:2 case-control study was performed in which LDH players and players without LDH were matched for player variables. Statistical analysis was employed to compare pre- and postindex season performance (games played and player efficiency rating [PER]) and career longevity between test subjects and controls in the operatively treated (OT) and nonoperatively treated (NOT) cohorts. A total of 61 NBA players with LDH were included, of whom 34 underwent discectomy and 27 were managed nonoperatively. Return-to-play (RTP) rates did not differ between NOT and OT players (77.8% vs. 79.4%). When compared with controls, OT players played significantly fewer games and had a lower PER than controls during the first postoperative season, but no difference was seen 2 and 3 years after surgery, with no difference in postoperative career length. In contrast, no difference in games played or PER was seen between NOT players and controls, although NOT players played significantly fewer postindex seasons. NBA players have a high RTP rate regardless of type of treatment for LDH; however, postindex performance differs between surgically and nonoperatively managed patients when compared with players without an LDH. However, further studies with a larger sample size are required for more definitive recommendations. There is a high RTP rate after LDH in the NBA, although postindex performance may differ based on operative versus nonoperative treatment. © 2015 The Author(s).

    Abstract The conventional location methods for minimally invasive spinal surgery (MISS) were mainly based on repeated fluoroscopy in a trial-and-error manner preoperatively and intraoperatively. Localization system mainly consisted of preoperative applied radiopaque frame and intraoperative guiding device, which has the potential to minimize fluoroscopy repetition in MISS. The study aimed to evaluate the efficacy of a novel lumbar localization system in reducing radiation exposure to patients. Included patients underwent minimally invasive transforaminal lumbar interbody fusion (MISTLIF) or percutaneous transforaminal endoscopic discectomy (PTED). Patients treated with novel localization system were regarded as Group A, and patients treated without novel localization system were regarded as Group B. For PTED, The estimated effective dose was 0.41 ± 0.13 mSv in Group A and 0.57 ± 0.14 mSv in Group B (P fluoroscopy exposure time of PTED was 22.18 ± 7.30 seconds in Group A and 30.53 ± 7.56 seconds in Group B (P fluoroscopy exposure time was 25.41 ± 5.52 seconds in Group A and 32.82 ± 5.03 seconds in Group B (P < .001); The estimated cancer risk was 24.90 ± 5.15 (10–6) in Group A and 31.96 ± 5.04 (10–6) in Group B (P < .001). There were also significant differences in localization time and operation time between the 2 groups either for MISTLIF or PTED. The lumbar localization system could be a potential protection strategy for minimizing radiation hazards. PMID:28538369

    A prospective cohort study with 100% follow-up. To assess incidence and risk factors for development of post-traumatic stress disorder (PTSD) symptoms after elective lumbar arthrodesis. Invasive medical care results in substantial physical and psychological stress to patients. The reported incidence of PTSD after medical care delivery in patients treated for trauma, cancer, and organ transplantation ranges from 5% to 51%. Similar data after elective lumbar spinal arthrodesis have not been reported. A consecutive series of 73 elective lumbar spine arthrodesis patients were evaluated prospectively, using the PTSD checklist-civilian version at 6 weeks, 3 months, 6 months, 9 months, and 12 months after surgery. Patient's sex, age, education level, job status, marital status, psychiatric history, prior surgery with general anesthetic, surgical approach, blood loss, postoperative intubation, length of intensive care unit and hospital stay, and occurrence of perioperative complications were analyzed as predictors of PTSD symptoms, using χ analyses. The overall incidence of symptoms of PTSD identified at at least 1 time point was 19.2% (14 of 73). At each time point, the percentage of the population that was positive was 7.5% (6 wk), 11.6% (3 mo), 7.8%, (6 mo), 13.6% (9 mo), and 11.0% (12 mo). The presence of a prior psychiatric diagnosis proved to be the strongest predictor of postarthrodesis symptoms of PTSD (odds ratio [OR] = 7.05, P = 0.002). Occurrence of a complication also proved to be significantly correlated with the development of PTSD symptoms (OR = 4.33, P = 0.04). Age less than 50 years, blood loss of more than 1 L, hospital stay of more than 10 days, and diagnosis trended toward but failed to reach statistical significance. None of the remaining variables approached statistical significance. Positive PTSD symptoms occurred at least once in 19.2% of patients after elective lumbar arthrodesis, with 7.5% to 13.6% of patients experiencing these symptoms at any 1

    To analyze the clinical effects of percutaneous transforaminal endoscopic technique in treating lumbar intervertebral disc herniation and sciatica. From June 2011 to January 2012,the clinical data of 46 patients with lumbar intervertebral disc herniation and sciatica underwent percutaneous transforaminal endoscopic technique were retrospectively analyzed. There were 28 males and 18 females,ranging in age from 11 to 77 years old with an average of (39.7_ 15.3) years old,20 cases were L5S1 and 26 cases were L4,5. All patients had the symptoms such as lumbago and sciatica and their straight-leg raising test were positive. Straight-leg raising test of patients were instantly repeated after operation;operative time,volume of blood loss,complication, length of stay and duration of back to work or daily life were recorded. The clinical effects were assessed according to the VAS,JOA and JOABPEQ score. All operations were successful,postoperative straight-leg raising test were all negative. Operative time,volume of blood loss,length of stay,duration of back to work or daily life,follow-up time were (93.0+/-28.0) min, (20.0+/-9.0)ml, (3.1+/-1.5) d, (11.6+/-4.2) d, (13.9+/-1.6) months,respectively.

    Full Text Available Enzyme replacement therapy with intravenous idursulfase (recombinant iduronate-2-sulfatase is approved for the treatment of Hunter syndrome. Intravenous administration does not, however, treat the neurological manifestations, due to its low central nervous system bioavailability. Using intrathecal-lumbar administration, iduronate-2-sulfatase is delivered directly to the central nervous system. This study investigates the central nervous system biodistribution of intrathecal-lumbar administered iduronate-2-sulfatase in cynomolgus monkeys. Twelve monkeys were administered iduronate-2-sulfatase in one 30 mg intrathecal-lumbar injection. Brain, spinal cord, liver, and kidneys were collected for iduronate-2-sulfatase concentration (measured by an enzyme linked immunosorbent assay and enzyme activity measurement (via a method utilizing 4-methylumbelliferyl-α-iduronate-2-sulfate at 1, 2, 5, 12, 24, and 48 hours following administration. The tissue enzyme linked immunosorbent assay confirmed iduronate-2-sulfatase uptake to the brain, spinal cord, kidneys, and liver in a time-dependent manner. In spinal cord and brain, iduronate-2-sulfatase appeared as early as 1 hour following administration, and peak concentrations were observed at ~2 and ~5 hours. Iduronate-2-sulfatase appeared in liver and kidneys 1 hour post intrathecal-lumbar dose with peak concentrations between 5 and 24 hours. Liver iduronate-2-sulfatase concentration was approximately 10-fold higher than kidney. The iduronate-2-sulfatase localization and enzyme activity in the central nervous system, following intrathecal administration, demonstrates that intrathecal-lumbar treatment with iduronate-2-sulfatase may be considered for further investigation as a treatment for Hunter syndrome patients with neurocognitive impairment.

    Full Text Available Disc cysts are uncommon intraspinal cystic lesions located in the ventrolateral epidural space. They communicate with the nucleus pulposus of the intervertebral disc and cause symptoms by radicular compression. We report a unique case of lumbar disc cyst that was associated with disc herniation and contralateral radiculopathy. A 22 year old male presented with one month history of back-ache radiating to the left leg. Magnetic Resonance Imaging (MRI showed L3-L4 disc herniation with annular tear and cystic lesion in the extradural space anterior to the thecal sac on right side, which increased in size over a period of 3 weeks. L3 laminectomy and bilateral discectomy and cyst excision was done with partial improvement of patients symptoms.

    Scattered reports exist in the medical literature regarding facet tropism. However, this finding has had mixed conclusions regarding its origin and impact on the normal spine. We performed a literature review of the anatomy, embryology, biomechanics, and pathology related to lumbar facet tropism. Facet tropism is most commonly found at L4-L5 vertebral segments and there is some evidence that this condition may lead to facet degenerative spondylolisthesis, intervertebral disc disease, and other degenerative conditions. Long-term analyses of patients are necessary to elucidate relationships between associated findings and facet tropism. In addition, a universally agreed definition that is more precise should be developed for future investigative studies. Copyright © 2017 Elsevier Inc. All rights reserved.

    Gas production as a part of disc degeneration can occur but rarely causes nerve compression syndromes. The clinical features are similar to those of common sciatica. CT is very useful in the detection of epidural gas accumulation and nerve root compression. We report a case of symptomatic epidural gas accumulation originating from vacuum phenomenon in the intervertebral disc, causing lumbo-sacral radiculopathy. A 45-year-old woman suffered from sciatica for 9 months. The condition worsened in recent days. Computed tomography (CT) demonstrated intradiscal vacuum phenomenon, and accumulation of gas in the lumbar epidural space compressing the dural sac and S1 nerve root. After evacuation of the gas, her pain resolved without recurrence.

  9. Adjacent Segment Pathology after Lumbar Spinal Fusion

    2015-01-01

    One of the major clinical issues encountered after lumbar spinal fusion is the development of adjacent segment pathology (ASP) caused by increased mechanical stress at adjacent segments, and resulting in various radiographic changes and clinical symptoms. This condition may require surgical intervention. The incidence of ASP varies with both the definition and methodology adopted in individual studies; various risk factors for this condition have been identified, although a significant controversy still exists regarding their significance. Motion-preserving devices have been developed, and some studies have shown their efficacy of preventing ASP. Surgeons should be aware of the risk factors of ASP when planning a surgery, and accordingly counsel their patients preoperatively. PMID:26435804

    To compare the usefulness of dynamic contrast enhanced lumbar spine MR imaging with that of conventional delayed contrast enhanced MR imaging in the assessment of postoperative herniated lumbar disc. Forty-one postoperative herniated lumbar disc (HLD) lesions of 32 patients with back pain were examined with MR imaging (1.5T, Vision, Siemens, Germany). Five-phase dynamic 2D FLASH sagittal images (TR/TE = 118.1msec/4.1msec) were obtained every 19 seconds with a 4 minutes delayed image after contrast injection. As seen on delayed images, the discs were assessed as recurred, fibrosis, or no change. On dynamic images, the pattern of enhancement was evaluated as follows : Type 1 (no change in peripheral disc enhancement between the early and late phases) ; or Type 2 (minimal internal extension of marginal smooth enhancement during the late phase) ; or Type 3 (marked internal extension of peripheral irregular enhancement). Dynamic and delayed imaging were compared, and early epidural space enhancement with rapid wash-out was also evaluated. Of 41 postoperative HLDs, 39 lesions showed peripheral contrast enhancement. Evaluation depended on delayed imaging, and was as follows : recurred HLD (n=27) ; fibrosis (n=5) ; no change in postoperative disc (n=7). On dynamic contrast-enhanced imaging, enhancement patterns were Type 1 (n=29), Type 2 (n=7), and Type 3 (n=3). In 29 Type 1 lesions, there were no significant differences in image findings between dynamic and delayed images. However, in ten lesions (type 2 : n=7, type 3 : n=3), findings additional to those revealed by delayed images were demonstrated by dynamic contrast-enhanced MR imaging. Nine of the ten Type 2 and 3 lesions were diagnosed as recurred HLD. On dynamic images, five lesions showed early epidural space enhancement. Dynamic contrast-enhanced lumbar spine MR imaging provided additional findings such as increased peripheral disc enhancement, and epidural space enhancement, which cannot be detected on

    Inverse dynamic musculoskeletal human body models are commonly used to predict the spinal loads and trunk muscle forces. These models include rigid body segments, mechanical joints, active and passive structural components such as muscles, tendons and ligaments. Several studies used simple definition of lumbar spinal discs idealized as spherical joints with infinite translational stiffness. The aim of the current sensitivity study was to investigate the influence of disc translational stiffness (shear and compressive stiffness) on the joint kinematics and forces in intervertebral discs (L1-L5), trunk muscles and ligaments for an intermediately flexed position (55°). Based on in vitro data, a range of disc shear stiffness (100-200N/mm) and compressive stiffness (1900-2700N/mm) was considered in the model using the technique of force dependent kinematics (FDK). Range of variation in spinal loads, trunk muscle forces and ligaments forces were calculated (with & without load in hands) and compared with the results of reference model (RM) having infinite translational stiffness. The discs' centers of rotation (CoR) were computed for L3-L4 and L4-L5 motion segments. Between RM and FDK models, maximum differences in compressive forces were 7% (L1-L2 & L2-L3), 8% (L3-L4) and 6% (L4-L5) whereas in shear forces 35% (L1-L2), 47% (L2-L3), 45% (L3-L4) and more than 100% in L4-L5. Maximum differences in the sum of global and local muscle forces were approximately 10%, whereas in ligament forces were 27% (supraspinous), 40% (interspinous), 56% (intertransverse), 58% (lig. flavum) and 100% (lig. posterior). The CoRs were predicted posteriorly, below (L3-L4) and in the disc (L4-L5). FDK model predicted lower spinal loads, ligament forces and varied distribution of global and local muscle forces. Consideration of translational stiffnesses influenced the model results and showed increased differences with lower stiffness values. Copyright © 2017 IPEM. Published by Elsevier Ltd. All

    2017-03-01

    Full Text Available Minimally invasive spine surgery prevents alteration of paraspinal muscles and avoids traditional open surgery, so in the majority of cases, recovery is much quicker and patients have less back pain after surgery. The authors describe an endoscopic approach to lumbar disc herniation by the Destandau's method originated in Bordeaux. Destandau designed ENDOSPINE for discectomy will be inserted, and the procedure will continue using endoscopy. The Endoscopic approach to lumbar disc herniation by Destandau's method offers a convenient access to lumbar disc herniation with less complications and negligible morbidity. It gives maximum exposure to the disc space with maximal angles and minimal cutaneous incision. Contrary to other minimally invasive approaches, the visual field in discectomy by Destandau technique is broad and depending on the workability of ENDOSPINE an adequate access to lumbar disc herniation is possible.

    Full Text Available Interspinous spacers were developed to treat local deformities such as degenerative spondylolisthesis. To treat patients with chronic instability, posterior pedicle fixation and rod-based dynamic stabilization systems were developed as alternatives to fusion surgeries. Dynamic stabilization is the future of spinal surgery, and in the near future, we will be able to see the development of new devices and surgical techniques to stabilize the spine. It is important to follow the development of these technologies and to gain experience using them. In this paper, we review the literature and discuss the dynamic systems, both past and present, used in the market to treat lumbar degeneration.

    Visual Impairment and Intracranial Pressure Syndrome (VIIP) has caused symptomatology during and after long duration missions on the International Space Station (ISS). Only indirect measurements of intracranial pressure (ICP), such as ultrasound, have been performed on ISS. Discussion and interest has happened at NASA about performing lumbar puncture (LP) in microgravity. Only the "blind" palpation approach and the ultrasound-assisted approach have been discussed. This article, as proof of concept, discusses the possibility of portable radiography to assist lumbar punctures in microgravity. An anthropomorphic radiological phantom of an adult lumbar spine was made containing a fluid-filled space in the spinal canal with a latex membrane which simulated the dural sac and cerebrospinal fluid. A portable direct-digital radiography system with wireless transmitting image receptor and screen was used to perform image-guided lumbar puncture. Using the same equipment and technique, this procedure was then performed on a cadaver for final proof of concept. Technical success was achieved in all approaches on the first try without needle redirection. There was no difference between the cadaver model and the phantom model in terms of difficulty in reaching the fluid space or visually confirming needle location. Portable radiography via proof of concept has the potential to guide lumbar puncture while minimizing volume and mass of equipment. This could be ideal for assisting in performing lumbar puncture in microgravity, as this is the standard of care on Earth for difficult or failed "blind" lumbar punctures.

    The mechanical properties of normal lumbar vertebra and one with the interarticular part cut off to simulate hemi-spondylolysis were measured by the double exposure holographic interferometry. In the normal lumbar vertebra, displacement due to the load applied to the inferior articular process was greater than that of superior articular process under the same load. The interarticular part was subjected to the high stress. From these points, one of the valuable data to consider the cause of spondylolysis was obtained.

    1992-01-01

    Of 46 patients who underwent a lumbar or lumbo-sacral anterior interbody fusion at one or two levels, 16 were available for a follow-up of 16-20 years. The indications for operation were instability, degenerative disc disease, pseudarthrosis of a posterior fusion, and spondylolisthesis. Preoperative roentgenograms were compared with those made at follow-up 16 years (or more) later. In only a minority of patients was discopathy or instability found. The roentgenographic findings of the operated patients at a follow-up of at least 16 years were compared with those of a group of age- and sex-matched controls not previously treated for backache. We found that most degenerative changes of the adjacent discs occurred at a rate nearly similar to that in the corresponding levels of the controls. These results may suggest that lumbar anterior interbody spondylodesis does not accelerate the development of degenerative changes in adjacent discs.

    Full Text Available ABSTRACT Spinal tuberculosis (Pott disease can produce severe deformities when it is not properly treated. Long instrumentations through single or combined double approaches are usually required to prevent and correct the deformity. The authors present a case of severe deformity secondary to tuberculous spondylodiscitis in the lumbar spine treated with a monosegmental instrumentation through a double approach in a patient with idiopathic scoliosis. Deformity correction and infection resolution through debridement and arthrodesis is observed after one year of follow-up.

    The term spondylodiscitis aims to describe any spinal infection. Medical treatment is the gold standard; nevertheless, surgical treatment can be indicated. The aim of this work was to study the epidemiological profile in a group of patients with spondylodiscitis surgically treated in the same medical institution between 1997 and 2013. Eighty five patients with spondylodiscitis were surgically treated in this period. The authors analysed clinical data and image studies for each patient. We treated 51 male and 34 female patients with an average age of 48 years old (min: 6 - max: 80). The lumbar spine was more often affected and Mycobacterium tuberculosis the most frequent pathogen. The number of cases through the years has been grossly stable, with a slight increase of dyscitis due to Staphylococcus aureus and decrease of the dyscitis without pathogen identification. Paravertebral abscess was identified in 39 patients and 17 had also neurological impairment, mostly located in the thoracic spine and with tuberculous aetheology. Immunosuppression was documented in 10 patients. In this epidemiologic study we found a tuberculous infection, male gender and young age predominance. Despite a relative constant number of patients operated over the years, pyogenic infections due to Staphylococcus aureus seems to be uprising. Paravertebral abscess and neurological impairment are important dyscitis complications, especially in tuberculous cases. Spinal infections requiring surgical treatment are still an important clinical condition. Mycobacterium tuberculosis and Staphylococcus aureus represent the main pathogens with a growing incidence for the latest.

Quantify cerebrospinal fluid leak closed by lumbar drainage with IP. Retrospective descriptive case series study. patients undergoing transsphenoidal pituitary surgery, Chiari surgery and laminectomy, that developed postoperative cerebrospinal fluid leak treated with continuous external lumbar drainage by IP. age, sex, type of intervention, variables related to the practice of the pump and complications. Average and medians were calculated for quantitative variables, frequencies and percentages for qualitative. Sample: 11 subjects. Incidence in running IP: disconnection, occlusion and acoustic alarm activation. Most frequently complication is headache; a case of pneumocephalus. The small number of subjects and the heterogeneity of these do not allow for comparison or establishing associations between variables. The resolution of the cerebrospinal fluid leak with continuous IP is lower in this study than others, and may be influenced by the small number of subjects. It should be noted the frequent activation of the pump alarm for no apparent cause. Protocol would be developed for preparing the IP team to reduce the acoustic alarm activation, and would make a prospective multicenter study. Copyright © 2016 Elsevier España, S.L.U.

    Ito, S.; Muro, T.; Eisenstein, S.

    1998-01-01

    Analysis of single photon emission computed tomographic images and plain X-ray films of the lumbar vertebrae was performed in 15 patients with lumbar spondylosis and 15 patients with lumbar degenerative spondylolisthesis. The facet joint and osteophyte images were observed in particular, and the slipping ratio of spondylolisthetic vertebrae was determined. The slipping ratio of degenerative spondylolisthesis ranged from 11.8 % to 22.3 %. Hot uptake of 99mTc-HMDP by both L4-5 facet joints was significantly greater in the patients with degenerative spondylolisthesis than in those with lumbar spondylosis. The hot uptake by the osteophytes in lumbar spondylosis was nearly uniform among the three inferior segments, L3-4, L4-5 and L5-S, but was localized to the spondylolisthetic vertebrae, L4-5, or L5-S, in the patients with spondylolisthesis. Half of the osteophytes with hot uptake were assigned to the 3rd degree of Nathan's grading. It was suggested that stress was localized to the slipping vertebrae and their facet joints in patients with lumbar degenerative spondylolisthesis. (author)

    In patients undergoing lumbar fusion, osteoporosis has been shown to lead to poorer outcomes and greater incidence of fusion-related complications. Given the undesirable effect of osteoporosis on lumbar fusion surgery, a number of medications have been proposed for use in the peri- and postoperative period to mitigate risks and enhance outcomes. The purpose of this review was to summarize and synthesize the current literature regarding medical management of osteoporosis in the context of lumbar fusion surgery. A literature search of PubMed, Embase, and Web of Science was conducted in October 2016, using permutations of various search terms related to osteoporosis, medications, and lumbar fusion. Teriparatide injections may lead to faster, more successful fusion, and may reduce fusion-related complications. Bisphosphonate therapy likely does not hinder fusion outcomes and may be useful in reducing certain complications of fusion in osteoporotic patients. Calcitonin and selective estrogen receptor modulator therapy show mixed results, but more research is necessary to make a recommendation. Vitamin D deficiency is associated with poor fusion outcomes, but evidence for supplementation in patients with normal serum levels is weak. Overall, the current body of research appears to support the use of teriparatide therapy to enhance lumbar fusion outcomes in the osteoporotic patient, although the extent of research on this topic is limited. Additionally, very little evidence exists to cease any of the mentioned osteoporosis treatments prior to lumbar fusion.

Because of their similar size to humans, pigs remain an important spine model. For pigs to serve as a model for the human spine, basic similarities and differences must be understood. In this study, morphometric data of the lumbar spine of Munich miniature pigs (Troll) were recorded radiologically, evaluated, and compared with recorded human data. Whereas humans have a constant number of 5 lumbar vertebrae, Munich minipigs had 5 or 6 lumbar vertebrae. Compared with their human counterparts, the lumbar vertebral bodies of the minipigs were remarkably larger in the craniocaudal (superior–inferior) direction and considerably smaller in the dorsoventral and laterolateral directions. The porcine vertebral canal was smaller than the human vertebral canal. The spinal cord extended into the caudal part of the porcine lumbar vertebral canal and thus did not terminate as cranial, as seen in humans. The lumbar intervertebral spaces of the pig were narrower in craniocaudal direction than human intervertebral spaces. These differences need to be considered when planning surgical actions, not only to avoid pain and irreversible damage to the minipigs but also to achieve accurate scientific results. PMID:27177570

    To investigate the incidence and risk of stroke after lumbar spinal fusion surgery. Study subjects were identified from a nationwide cohort of 1 million people from 2000 to 2005 and were divided into the lumbar spinal fusion group (n = 2,015), who received posterior lumbar spinal fusion surgery, and the comparison group (n = 16,120) composed of age-, sex-, and propensity score-matched control subjects. The matching process was intended to adjust for demographics, comorbidities, and other immeasurable covariates to minimize selection bias. All subjects were followed up for 3 years for stroke, including hemorrhagic and ischemic strokes. Kaplan-Meier and Cox regression analyses were performed. The overall incidence rate of stroke in the cohort was 9.99 per 1,000 person-year. The lumbar spinal fusion group was less likely to have any stroke (adjusted hazard ratio (HR) = 0.83, p = 0.293), hemorrhagic stroke (adjusted HR = 0.74, p = 0.739) and ischemic stroke (adjusted HR = 0.81, p = 0.250) than the comparison group, but without significance. Three years post-operatively, patients who received lumbar spinal fusion had stroke incidence rates similar to those without surgery. Posterior lumbar spinal fusion surgery is not associated with increased risks for any kind of stroke.

    To explore the method and clinical effect of MAST Quadrant for lumbar spondylolisthesis with adjacent segment degeneration. From April 2014 to January 2016, 36 cases of lumbar spondylolisthesis with adjacent segment degeneration were treated by MAST Quadrant(target nerve decompression and transforaminal lumbar interbody fusion or articulationes zygapophysiales fusion by unilateral fixation with MAST Quadrant). Twenty-three cases were degenerative lumbar spondylolisthesis and 13 cases were isthmic lumbar spondylolisthesis. According to Meyerding grade of spondylolisthesis, 16 cases were grade I, 17 cases were grade II, and 3 cases were grade III. Visual analogue score (VAS), Oswesty Disability Index (ODI) and JOA score were used to evaluate the clinical outcome. The amount of intraoperative bleeding was 230 to 480 ml with an average of 340 ml and the amount of postoperative blood loss was 15 to 80 ml with an average of 43 ml. Operative time was 176 to 240 min with an average of 193 min; X-ray exposure time was 2 to 6 s with an average of 3.6 s. Two cases were complicated with dural tear without nerve injury during operation. Thirty cases were followed up from 12 to 17 months with an average of 15.2 months. VAS scores for preoperative, 5 days, 3 months after surgery were 7.6±1.7, 1.9±0.4, 0.8±0.4 respectively, and there was significant difference before and after operation( P <0.05). The ODI scores for preoperative and 3 months after surgery were 35.9±1.2 and 3.7±0.7 respectively, and there was significant difference before and after operation( P <0.05). JOA scores for preoperative, 5 days, 1 months, 3 months after surgery were 13.2±0.4, 24.4±0.4, 27.4±0.1, 27.9±0.5 respectively, and there was significant difference before and after operation( P <0.05). MAST Quadrant can be applied to treat lumbar spondylolisthesis with adjacent segment degeneration, and the minimally invasive sugical technique is a safe and effective method, with the advantage of simple

    Bone metastases at the thoracic and lumbar segment of the spine are usually presented with painful sensation and medullar compression. The treatment is based on the clinical and neurological conditions of the patient and the degree of tumor invasion. In the present study, 32 patients with spinal metastasis of thoracic and lumbar segment were prospectively analyzed. These patients were treated by decompression and internal stabilization followed by radiotherapy or irradiation with external immobilization. The election of the groups was in accordance with the tumor radiotherapy sensitivity, clinical conditions, spinal stability, medullar or nerve compression and patient's decision. The Frankel scale and pain visual test were applied at the moment of diagnosis and after 1 and 6 months. The surgical group had better results with preserving the ambulation longer and significant reduction of pain.(author)

    Prognosis of minor lumbar curve correction after selective thoracic fusion in idiopathic scoliosis is well defined. However, the prognosis of minor thoracic curve after isolated anterior fusion of the major lumbar curve has not been well described. To define the prognosis of spontaneous thoracic curve correction after selective anterior fusion of the lumbar/thoracolumbar curve in idiopathic scoliosis. A retrospective cohort study on the prognosis of the minor curve after selective anterior correction and fusion of the lumbar/thoracolumbar curve in idiopathic scoliosis. Idiopathic lumbar scoliosis patients treated with anterior spinal fusion. The Scoliosis Research Society 22 questionnaire was used as an outcome measure at the final follow-up. Twenty-eight patients were included in this study. Four patients were male, 24 patients were female, and average age at the time of surgery was 16 years. Mean follow-up was 48 months. According to the Lenke Classification, 22 patients were 5CN, 5 were 5C-, and 1 was 5C+. All operations were performed in the same institution. Standing long posterior-anterior and lateral radiographs were taken just before surgery, 1 week after surgery, and at final follow-up. The mean preoperative Cobb angle of the lumbar (major) curve was 53° (standard deviation [SD]=8.6) and that of the thoracic (minor) curve was 38.4° (SD=6.24). The lumbar and thoracic curves were corrected to 10° (SD=7.6) and 25° (SD=8.3) postoperatively and measured 17° (SD=10.6) and 27° (SD=7.7), respectively, at the last follow-up. There was a significant difference between the preoperative and postoperative measurements of the minor curves (p.05). Regarding the overall sagittal balance, there was no significant difference between preoperative, early, and late postoperative measurements (p>.05). Selective anterior fusion of the major thoracolumbar/lumbar curve was an effective method for the treatment of Lenke Type 5C curves. Minor thoracic curves did not progress

    Whether compensation for professional services drives the use of those services is an important question that has not been answered in a robust manner. Specifically, there is a growing concern that spine care practitioners may preferentially choose more costly or invasive procedures in a fee-for-service system, irrespective of the underlying lumbar disorder being treated. (1) Were proportions of interbody fusions higher in the fee-for-service setting as opposed to the salaried Department of Defense setting? (2) Were the odds of interbody fusion increased in a fee-for-service setting after controlling for indications for surgery? Patients surgically treated for lumbar disc herniation, spinal stenosis, and spondylolisthesis (2006-2014) were identified. Patients were divided into two groups based on whether the surgery was performed in the fee-for-service setting (beneficiaries receive care at a civilian facility with expenses covered by TRICARE insurance) or at a Department of Defense facility (direct care). There were 28,344 patients in the entire study, 21,290 treated in fee-for-service and 7054 treated in Department of Defense facilities. Differences in the rates of fusion-based procedures, discectomy, and decompression between both healthcare settings were assessed using multinomial logistic regression to adjust for differences in case-mix and surgical indication. TRICARE beneficiaries treated for lumbar spinal disorders in the fee-for-service setting had higher odds of receiving interbody fusions (fee-for-service: 7267 of 21,290 [34%], direct care: 1539 of 7054 [22%], odds ratio [OR]: 1.25 [95% confidence interval 1.20-1.30], p service setting irrespective of the underlying diagnosis. These results speak to the existence of provider inducement within the field of spine surgery. This reality portends poor performance for surgical practices and hospitals in Accountable Care Organizations and bundled payment programs in which provider inducement is allowed to

    Can a mixture of hydroxyapatite (HA) and autologous bone from decompression sites produce similar results when used for transforaminal lumbar interbody fusion (TLIF)? In the current literature, autologous iliac crest bone grafts (ICBGs) have been reported the gold standard for this procedure. Indeed, to date, no clinical data have confirmed that a mixture of equal volumes of HA and local autologous bone produce similar results in term of fusion as the same volume of autologous ICBG alone. Study design/setting This study was approved by the local ethics committee and completed in a prospective, randomized, single-blinded manner. The results of lumbar fusion using TLIF and different bone grafting materials were compared. Patient sample The patient sample included patients with spinal lumbar degenerative disease. Outcome measures The clinical outcome was determined using the Oswestry Low Back Pain Disability Questionnaire (ODI) and Visual Analog Scale (VAS). The radiological outcomes and fusion rates were determined with radiographs evaluated using the McAfee criteria and computed tomography (CT) data evaluated by the Williams criteria. Three blinded investigators (one radiologist and two orthopedic surgeons) assessed the data. The secondary variables included donor site morbidity. Methods The patients were admitted to our department for orthopedic surgery with degenerative lumbar pathologies (L2-S1) that required stabilization in one or two segments using a TLIF procedure. The patients were 18-80 years old. Only those patients who had degenerative lumbar pathologies and agreed to be educated about the study were included. The patients were divided into the following two randomized groups: group A: TLIF procedure using autologous ICBGs alone; and group B: TLIF procedure using local bone from decompression site mixed with hydroxyapatite. Each group received equal graft volumes. The mixture in group B consisted of equal volumes of local autograft (5 cc) and synthetic

    206 patients scheduled for spinal surgery (lumbar discopathy) were randomly premedicated with diclofenac, pethidine, diazepam or hydroxizine. The frequency of persisted postoperative pain was evaluated from the 3-ed. postoperative day to the end of hospitalisation--as the need for additional concomitant treatment with dexamethasone and intravenous analgesics. The frequency of persisted pain was significantly decreased in patients premedicated with diclofenac (together with diazepam) before spinal surgery (limited to fenestration) in comparison to patients premedicated with pethidine. The pre-emptive analgesic effect of diclofenac was even more evident in patients treated with non-steroidal anti-inflammatory drugs (NSAID) before surgery, but was not observed in patients after more traumatic surgery (laminectomy) premedicated with diazepam. The results are supporting the important role of NSAID given before surgery to decrease the frequency of persisted pain after spinal surgery (limited to fenestration), in patients treated with NSAID.

    Lumbar posterior apophyseal ring fracture is an uncommon finding in children, but lumbar spondylolysis is a common disorder. Both disorders are prevalent in young athletes. We describe 3 adolescent athletes who showed both lumbar spondylolysis and lumbar posterior apophyseal ring fracture. Because lumbar spondylolysis is comparatively easy to diagnose, a concurrent posterior lumbar apophyseal ring fracture is likely to be overlooked. In patients with severe low back and radicular pain in whom spondylolysis is suspected, it is important to perform not only magnetic resonance imaging and radiography but also computed tomography for identifying posterior apophyseal ring fractures.

    In the geriatric population, pain with sciatic irradiation requires a differential diagnosis to enable a distinction to be made mainly between a herniated disc, lateral recess stenosis or lumbar stenosis. In addition, in many cases the degenerative problems are often associated with lumbar listhesis or instability. Furthermore, these patients present very diverse associated cardiovascular, pulmonary or metabolic pathologies which can make surgery complicated and, above all, prolong post-operative recovery, as well as increasing morbidity and mortality. We reviewed a group of 50 patients aged between 70 and 87 who had been submitted to surgery between 1997 and 2003; 27 were females and 23 males. 76% of them presented associated systemic pathologies and 22% had a history of previous spinal surgery. In 15 cases clinical symptoms were gait disorders involving claudication, there were three cases of paraparesis with cauda equina syndrome, 19 lumbagos with bilateral sciatica and 16 cases of lumbago with unilateral sciatica. Unilateral decompression hemilaminectomy was performed in 16 patients (group I) with microdiscectomy in 13 cases, laminectomy of one or several vertebrae (group II) was carried out in 17 patients and another 17 patients were submitted to decompression laminectomy plus arthrodesis with transpedicular instrumentation (group III). Overall a significant improvement was observed in 86% of patients. Detected complications involved two serious deep infections (4%), one of which was secondary to cerebrospinal fluid fistula, and the other occurred in an instrumented patient. No instabilities secondary to the laminectomy were observed in non-instrumented patients. No intraoperative anaesthetic or surgical complications were produced. Patients are followed up simultaneously during the post-operative period by both Internal Medicine and Neurosurgery. In the geriatric population there is a high incidence of degenerative problems, not only involving canal stenosis

    The objective of this study was to assess the reduction in quality of life (QoL) caused by the persistence of primary plantar hyperhidrosis (PPH) symptoms and the level of satisfaction in PPH patients after retroperitoneoscopic lumbar sympathectomy (RLS). The efficacy, safety, and procedure of bilateral RLS in both sexes are also described in this study. This is a longitudinal study of consecutive patients who sought specific treatment from a private practitioner for severe PPH as classified on the Hyperhidrosis Disease Severity Scale (HDSS) from October 2005 to October 2014. The patients were asked to report the symptoms of PPH experienced in the immediate preoperative period and to complete a standardized QoL questionnaire developed by de Campos at least 12 months after RLS. Disease outcomes, recurrence of symptoms, and any adverse effects of surgery were evaluated after 30 days and at least 12 months after RLS. Lumbar sympathectomy was performed 116 times in 58 patients; 30 days after surgery, PPH was resolved in all patients. Three patients (5.2%) reported transient thigh neuralgia, and 19 (32.7%) reported transient paresthesia in the lower limbs. There were no reports of retrograde ejaculation. At a minimum of 12 months after RLS, 49 of the 58 patients had fully and correctly answered the follow-up questionnaire and noted a mild (HDSS 2) to moderate (HDSS 3) increase in pre-existing compensatory sweating. One patient had a PPH relapse within 6 months. Improvement in QoL due to the resolution of PPH was reported in 98% of the 49 patients. None of the operations necessitated a change in the laparotomy approach, and none of the patients died. RLS is safe and effective for the treatment of severe PPH in both sexes. There were no reports of retrograde ejaculation after resection of L3 and L4 ganglia. There was a mild to moderate increase in compensatory sweating in about half of the patients, but without any regret or dissatisfaction for having undergone the

    A growing number of studies focus on sex differences in the pre- and postoperative setting in patients with degenerative disc disease (DDD). The exact pathomechanism behind this phenomenon, however, remains unclear. The objective of this study was to investigate pre- and postoperative sex differences in patients with lumbar DDD. In a prospective two-center study, back and leg pain (Visual Analogue Scale (VAS)), functional disability (Oswestry Disability Index (ODI) and Roland-Morris Disability Index) and health-related quality of life (HRQoL) (EuroQol 5D and Short-Form (SF12)) were collected for patients scheduled for lumbar spine surgery. In addition to the subjective functional impairment (SFI), objective functional impairment (OFI) was estimated using age- and sex-adjusted cut-off values for the timed-up-and-go (TUG) test. The 6-week responder status was defined using minimally clinically important differences of the ODI, SF12 PCS, VAS back and leg pain in all patients. Six months and one year follow-up (FU) was available in n=127 and n=87 patients, respectively. The patient cohort comprised of n=214 patients (41.6% females). Preoperatively, female patients scored significantly worse on VAS back and leg pain, ODI and SF12 PCS (psex-related differences had resolved for SFI and OFI was similar as well (p=0.333). There were no sex differences in the mean improvement after 6 weeks for all measures of pain intensity, functional impairment and HRQoL (p>0.182). Male and female patients profited equally on measures of SFI and HRQoL up to six months and one year after surgery (p>0.091). Preoperatively, female patients scored worse in terms of SFI, while OFI was similar. Consecutively, OFI appears to be less prone to sex bias and may thus serve as a valuable surrogate-marker of disability. The disadvantageous preoperative SFI-status did not translate into worse postoperative results, as no sex differences were present at the 6-week, 6-months and 1-year follow

Various modalities of treatments are utilized in managing discogenic and axial low back pain including epidural injections. However, there is a paucity of evidence regarding the effectiveness, indications, and medical necessity of any treatment modality utilized for managing axial or discogenic pain, including epidural injections. In an interventional pain management practice in the US, a randomized, double-blind, active control trial was conducted. The objective was to assess the effectiveness of lumbar interlaminar epidural injections of local anesthetic with or without steroids for managing chronic low back pain of discogenic origin. However, disc herniation, radiculitis, facet joint pain, or sacroiliac joint pain were excluded. Two groups of patients were studied, with 60 patients in each group receiving either local anesthetic only or local anesthetic mixed with non-particulate betamethasone. Primary outcome measures included the pain relief-assessed by numeric rating scale of pain and functional status assessed by the, Oswestry Disability Index, Secondary outcome measurements included employment status, and opioid intake. Significant improvement or success was defined as at least a 50% decrease in pain and disability. Significant improvement was seen in 77% of the patients in Group I and 67% of the patients in Group II. In the successful groups (those with at least 3 weeks of relief with the first two procedures, the improvement was 84% in Group I and 71% in Group II.

    The established protocols of treatment of postoperative lumbar discitis have not been validated till date. We report a retrospective analysis of a series of patients with discitis following single level lumbar discectomy. We analyzed the outcome of conservative treatment of postoperative discitis with the objective to define when and what surgery was required when the conservative treatment failed. A total of 17 cases of postoperative discitis treated from 2002 to 2009 were followed up and evaluated clinically, radiologically and by laboratory investigations. All the patients were treated initially conservatively with rest and antibiotic therapy after diagnosis and those who did not respond to conservative treatment of at least 4 weeks were treated surgically. The cases were followed up with serial C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), X-ray, computed tomography (CT) scan and magnetic resonance imaging (MRI) for at least 1 year. The mean followup was 40.38 months (range 12-86 months). Four cases failed to respond to conservative therapy and were treated surgically. In three of these four cases, open debridement, transpedicular fixation and posterolateral fusion was performed, and in the fourth case percutaneous transpedicular fixation was done. In the former group, one case was diagnosed to be tubercular, in another case Staphylococcus aureus was cultured where as the third case culture was sterile. All operated patients showed evidence of interbody fusion at 1 year followup. Early detection and aggressive treatment are paramount in managing postoperative discitis and the majority do well with conservative treatment. Surgical management in the form of transpedicular fixation and debridement, when required, gives excellent results.

    Transforaminal percutaneous endoscopic lumbar discectomy (PELD) for high-grade migrated disc herniation has been regarded as a challenging task, but because of the remarkable improvement in navigable instruments and advanced epiduroscopic technique, it can be used for the treatment of high- or very high-grade migrated disc herniation. The purpose of this study was to describe in detail the standardized technique of transforaminal PELD for very high-grade migrated disc herniation and demonstrate the clinical results. Very high-grade lumbar migrated disc herniation was defined as a disc migration beyond the inferior margin of the pedicle. Thirteen consecutive patients with very high-grade lumbar migrated disc herniation were treated with transforaminal PELD, which has three stages: (1) direction-oriented transforaminal approach, (2) release of periannular anchorage, and (3) epiduroscopic fragmentectomy with navigable instruments. The surgical outcomes were assessed using the visual analogue pain score (VAS), Oswestry disability index (ODI), and modified Macnab criteria. The operated levels were L3-4 in 2 (15.4%) patients, L4-5 in 10 (76.9%), and L5-S1 in 1 (7.7%). The directions of migration were cranial in 8 patients and caudal in 5. The mean VAS for leg pain improved from 7.86±1.28 preoperatively to 2.54±1.51 at 6 weeks postoperatively and 1.85±1.07 at 1year postoperatively (Pdisc herniation, and a standardized technique may provide a reliable and reproducible result.

    Objective: To assess the feasibility and efficacy of a novel, minimally invasive spinal surgery technique for the correction of lumbar spinal stenosis involving unilateral approach for bilateral decompression. Study Design: Cross-sectional observational study. Place and Duration of Study: Neurosurgery Department of PGMI, Lady Reading Hospital, Peshawar, from January to December 2010. Methodology: A total of 60 patients with lumbar stenosis were randomly assigned to undergo either a conventional laminectomy (30 patients, Group A), or a unilateral approach (30 patients, Group B). Clinical outcomes was measured using the scale of Finneson and Cooper. All the data was collected by using a proforma and different parameters were assessed for a minimum follow-up period of three months. Data was analyzed by descriptive statistics using SPSS software version 17. Results: Adequate decompression was achieved in all patients. Compared with patients in the conventional laminectomy group, patients who received the novel procedure (unilateral approach) had a reduced mean duration of hospital stay, a faster recovery rate and majority of the patients (88.33%) had an excellent to fair operative result according to the Finneson and Cooper scale. Five major complications occurred in all patient groups, 2 patients had unintended dural rent and 2 wound dehiscence each and fifth patient had worsening of symptoms. There was no mortality in the series. Conclusion: The ultimate goal of the unilateral approach to treat lumbar spinal stenosis is to achieve adequate decompression of the neural elements. An additional benefit of a minimally invasive approach is adequate preservation of vertebral stability, as it requires only minimal muscle trauma, preservation of supraspinous/intraspinous ligament complex and spinous process, therefore, allows early mobilization. This also shortens the hospital stay, reduces postoperative back pain, and leads to satisfactory outcome. (author)

In these studies, varying procedural techniques were utilized to ablate the nerves that innervate the facet joints. To date, no comparison studies have been performed to suggest superiority of one technique or even compare the prevalence of side effects and complications. Materials and methods: A retrospective chart review was performed on patients who underwent a lumbar facet denervation procedure. Each patient's chart was analyzed for treatment technique (early versus advanced Australian, preprocedural visual numeric scale (VNS score, postprocedural VNS score, duration of pain relief, and complications. Results: Pre- and postprocedural VNS scores and change in VNS score between the two groups showed no significant differences. Patient-reported benefit and duration of relief was greater in the advanced Australian technique group (P=0.012 and 0.022, respectively. The advanced Australian technique group demonstrated a significantly greater median duration of relief (4 months versus 1.5 months, P=0.022. Male sex and no pain-medication use at baseline were associated with decreased postablation VNS scores, while increasing age and higher preablation VNS scores were associated with increased postablation VNS scores. Despite increasing age being associated with increased postablation VNS scores, age and the advanced Australian technique were found to confer greater patient self-reported treatment benefit. Conclusion: The advanced Australian technique provides a significant benefit over the early Australian technique for the treatment of lumbar facet pain, both in

    Study Design Case report. Objective The purpose of this report is to discuss the surgical management of lumbar vertebral osteomyelitis with a spinal epidural abscess (SEA) and present a single-stage, posterior-only circumferential decompression and reconstruction with instrumentation using an expandable titanium cage and without segmental nerve root sacrifice as an option in the treatment of this disease process. Methods We report a 42-year-old man who presented with 3 days of low back pain and chills who rapidly decompensated with severe sepsis following admission. Magnetic resonance imaging of his lumbosacral spine revealed intramuscular abscesses of the left paraspinal musculature and iliopsoas with SEA and L4 vertebral body involvement. The patient failed maximal medical treatment, which necessitated surgical treatment as a last resort for infectious source control. He underwent a previously undescribed procedure in the setting of SEA: a single-stage, posterior-only approach for circumferential decompression and reconstruction of the L4 vertebral body with posterior segmental instrumented fixation. Results After the surgery, the patient's condition gradually improved; however, he suffered a wound dehiscence necessitating a surgical exploration and deep wound debridement. Six months after the surgery, the patient underwent a revision surgery for adjacent-level pseudarthrosis. At 1-year follow-up, the patient was pain-free and off narcotic pain medication and had returned to full activity. Conclusion This patient is the first reported case of lumbar osteomyelitis with SEA treated surgically with a single-stage, posterior-only circumferential decompression and reconstruction with posterior instrumentation. Although this approach is more technically challenging, it presents another viable option for the treatment of lumbar vertebral osteomyelitis that may reduce the morbidity associated with an anterior approach.

    A retrospective review of prospectively collected radiographic and clinical data. This study aims to investigate the relationship between cage subsidence and bone mineral density (BMD), and to reveal the clinical implications of cage subsidence. Posterior lumbar interbody fusion (PLIF) has become one of the standard treatment modality for lumbar degenerative disease. However, cage subsidence might result in recurrent foraminal stenosis and deteriorate the clinical results. Furthermore, numbers of osteoporosis patients who underwent PLIF are increasing. Therefore, the information on the correlations between cage subsidence, BMD, and clinical results will be of great significance. A total 139 segments was included in this retrospective study. We examined functional rating index (Visual Analogue Scale for pain, Oswestry Disability Index, Short Form-36 score) preoperatively, and investigated their changes after postoperative 1 year. Correlation between cage subsidence and clinical scores was investigated. Plain anteroposterior and lateral radiograph were taken preoperatively and postoperatively and during follow-up. Preoperative BMD and subsidence measured by postoperative 1 year 3-dimensional computed tomography were achieved and their correlation was assessed. All postoperative clinical scores improved significantly compared with preoperative ones (pain Visual Analogue Scale: 7.34-2.89, Oswestry Disability Index: 25.34-15.86, Short Form-36: 26.45-16.46, all Psubsidence (r=-0.285, Psubsidence (>3 mm) compared with the segments in which T score were higher than -3.0 (P=0.012), and its odds ratio was 8.44. Subsidence had no significant correlation with all clinical scores. This study revealed that cage subsidence is relevant to BMD. However, it was demonstrated that subsidence is not related to the clinical deterioration. Therefore, PLIF procedure which is conducted carefully can be a good surgical option to treat lumbar degenerative disease for osteoporotic patients.

    To understand the location characteristics of the lumbosacral autonomic nerve plexus and the morphological changes so as to provide the anatomic theoretical basis for the protection of autonomic nerve during the lower lumbar anterior approach operation. A random anatomic investigation was carried out on 19 formalin-treated adult cadavers (15 males and 4 females; aged 44-78 years, mean 64 years). The anterior median line (connection of suprasternal fossa point and the midpoint of the symphysis pubis) was determined, and the characteristics of abdominal aortic plexus (AAP), inferior mesenteric plexus (IMP), and superior hypogastric plexus (SHP) were observed. The relationship between the autonomic nerve and the anterior median line was measured and recorded. APP and IMP were found to be located chiefly in front of the abdominal aorta in a reticular pattern, and the nerve fibers of the two nerve plexuses were more densely at the left side of abdominal aorta than at the right side. Superior hypogastric plexus showed more distinct main vessel variations, including 4 types. The main vessel length of the SHP was (59.38 ± 12.86) mm, and the width was (11.25 ± 2.92) mm. The main vessels of SHP were mainly located at the left side of the ventral median line (10, 52.6%) and anterior lumbar vertebra (13, 68.4%). The main vessels extended down to form the left and right hypogastric nerves. It is applicable to expose the nerve from the right side of centrum and move the autonomic nerve and blood vessel as a whole during anterior lower lumbar operation. In this way, the dissection to separate nerve plexus is not needed, thus nerve injury can be avoided to the largest extent.

    Pain afflictions are the basic problems in patients with discopathy of the lumbar backbone. Pain control is the key therapeutic task in patients with a disease of the intervertebral disc. Degree of reduction of the pain sensations is one of the most important criteria in assessment of the treatment efficacy. of this study was to evaluate the pain afflictions in patients with lumbar discopathy treated with conservative and operative therapies. 665 patients aged between 16 and 76 years with discopathy at L4-L5 and L5-S1 levels have been enrolled to the study. In estimated group 348 patients received only a conservative therapy whereas 317 patients undergone an operative procedure. Analysis has been performed based on pain rating scores: Low Back Pain Rating Scale (LBPRS), Japanese Orthopedic Association Low Back Pain Score (JOA-LBPS), Domial's pain rating score. Results of performed studies show that conservative and operative treatment significantly alleviate pain affliction in patients with lumbar discopathy. Complete abatement of pain afflictions more frequent refers to operated patients than those only receiving conservative therapy. Alleviation of pain afflictions within a period of three years following operating procedure is significantly higher than within analogous period of conservative treatment. Reduction of pain obtained as a result of surgical procedure in higher degree refers to limb than backbone. Treatment method does not exert an influence on nature of pain afflictions within distant period. Alleviation of pain afflictions within a period of three years following operating procedure is significantly higher than within analogous period of conservative treatment. Treatment method does not exert an influence on nature of pain afflictions within distant period. Patients at the age of above 50 notify the higher level of intensity of pain ailments than young patients and patients in mid age.

    Sacrectomy and ilio-lumbar reconstruction is an uncommonly performed complex surgical procedure for the treatment of sacral neoplasia. There are many challenges in the post-operative period including the potential for tumor recurrence, infection, and construct failure. We present our experience of this patient cohort and describe the complications and imaging appearances that can be encountered during the follow-up period. Retrospective review of our Orthopaedic Oncology database was undertaken which has been collected over a 30-year period to identify patients that had undergone sacrectomy and ilio-lumbar reconstruction. Pre and post-operative imaging including radiographs, CT, and MRI was reviewed. These were viewed by two experienced musculoskeletal radiologists with consensus opinion if there was disagreement over the imaging findings. Data regarding patient demographics, tumor type, and dimensions was collected. Serial review of radiographs, CT, and MRI was performed to assess implant position and integrity, strut graft position and union, and for the presence of recurrence within the surgical bed. Five male and two female patients (mean age 36 years, age range 15-54 years) were treated with this procedure. Histological diagnoses included chordoma, chondrosarcoma, osteosarcoma, and spindle cell sarcoma. Mean maximal tumor size on pre-operative imaging was 10.7 cm (range, 6-16 cm). Post-operative follow-up ranged from 10-46 months. A total of 76 imaging studies were reviewed. Commonly identified complications included vertical rod and cross-connector fracture and screw loosening. Fibula strut graft non-union and fracture was also evident on imaging review. Two patients demonstrated disease recurrence during the follow-up period. This study demonstrates the spectrum and frequency of complications that can occur following sacrectomy and ilio-lumbar reconstruction for sacral neoplasia. (orig.)

    OBJECT Failed solid bony fusion, or pseudarthrosis, is a well-known complication of lumbar arthrodesis. Recent advances in radiographic technology, biologics, instrumentation, surgical technique, and understanding of the local biology have all aided in the prevention and treatment of pseudarthrosis. Here, the current literature on the diagnosis and management of lumbar pseudarthroses is reviewed. METHODS A systematic literature review was conducted using the MEDLINE and Embase databases in order to search for the current radiographie diagnosis and surgical treatment methods published in the literature (1985 to present). Inclusion criteria included: 1) published in English; 2) level of evidence I-III; 3) diagnosis of degenerative lumbar spine conditions and/or history of lumbar spine fusion surgery; and 4) comparative studies of 2 different surgical techniques or comparative studies of imaging modality versus surgical exploration. RESULTS Seven studies met the inclusion criteria for current radiographie imaging used to diagnose lumbar pseudarthrosis. Plain radiographs and thin-cut CT scans were the most common method for radiographie diagnosis. PET has been shown to be a valid imaging modality for monitoring in vivo active bone formation. Eight studies compared the surgical techniques for managing and preventing failed lumbar fusion. The success rates for the treatment of pseudarthrosis are enhanced with the use of rigid instrumentation. CONCLUSIONS Spinal fusion rates have improved secondary to advances in biologies, instrumentation, surgical techniques, and understanding of local biology. Treatment of lumbar pseudarthrosis includes a variety of surgical options such as replacing loose instrumentation, use of more potent biologies, and interbody fusion techniques. Prevention and recognition are important tenets in the algorithm for the management of spinal pseudarthrosis.

    The objective of this study is to analyze CSF red blood cell (RBC) count from first-attempt lumbar punctures and to analyze parameters associated with first-attempt lumbar punctures and hemorrhagic lumbar puncture. This is a prospective analysis of consecutive patients who underwent lumbar puncture for any reason other than suspected acute subarachnoid hemorrhage. Analyzed parameters were the following: age, indication for lumbar puncture, aPTT ratio, PTT, platelet count, patient's position, needle type (atraumatic/standard), needle diameter, person performing lumbar puncture (medical student/resident/attending physician), number of lumbar levels punctured, necessity of needle repositioning, CSF RBC and white blood cell count, and protein level. Lumbar puncture resulting in RBC count > 5 RBC/mm 2 was classified as hemorrhagic lumbar puncture (different cut-offs were studied: > 5/> 10/> 100/> 500/> 1000 RBC). In total, 169 elective lumbar punctures in 165 different patients were included. First-attempt lumbar puncture occurred in 22% > 5 RBC, in 19.5% > 10 RBC, in 4.5% > 100 RBC, in 3% > 500 RBC, and 1.5% > 1000 RBC count. First-attempt lumbar puncture was associated with non-hemorrhagic lumbar puncture for each of the RBC count cut-offs (OR for non-hemorrhagic lumbar puncture in first-attempt lumbar puncture 2.8, 95% CI 1.4-5.7). The presence of a hemorrhagic disorder (concerning cerebral amyloid angiopathy in all patients) and higher aPTT ratio were associated with hemorrhagic lumbar puncture. Atraumatic needle use was associated with non-hemorrhagic lumbar puncture for RBC count cut-offs ≤ 5 and ≤ 10 RBC (OR for non-hemorrhagic lumbar puncture in atraumatic needle use 2.5 [95% CI 1.3-4.8] and 2.2 [95% CI 1.1-4.4], respectively). First-attempt lumbar puncture and hemorrhagic lumbar puncture were not associated with other parameters. Slightly elevated CSF RBC count after first-attempt lumbar puncture occurs relatively frequently, but is even more

    Abstract Recurrent lumbar disc herniation (rLDH) is a common complication following primary discectomy. This systematic review aimed to investigate the current evidence on risk factors for rLDH. Cohort or case-control studies addressing risk factors for rLDH were identified by search in Pubmed (Medline), Embase, Web of Science, and Cochrane library from inception to June 2015. Relevant results were pooled to give overall estimates if possible. Heterogeneity among studies was examined and publication bias was also assessed. A total of 17 studies were included in this systematic review. Risk factors that had significant relation with rLDH were smoking (OR 1.99, 95% CI 1.53–2.58), disc protrusion (OR 1.79, 95% CI 1.15–2.79), and diabetes (OR 1.19, 95% CI 1.06–1.32). Gender, BMI, occupational work, level, and side of herniation did not correlate with rLDH significantly. Based on current evidence, smoking, disc protrusion, and diabetes were predictors for rLDH. Patients with these risk factors should be paid more attention for prevention of recurrence after primary surgery. More evidence provided by high-quality observational studies is still needed to further investigate risk factors for rLDH. PMID:26765413

    Along with the population aging in China, patients with lumbar spinal stenosis(LSS) caused by recessive change incessantly increase. At present, there is no adequate evidence to recommend any specific nonoperative treatment for LSS, and surgery is still an effective method. The cilincal symptoms of the patients without conservative treatment got improvement after surgery, which is the strongest evidence base. Spinal instability after simple decompression promotes the development of fusion technique, and the accelerated adjacent segment degeneration and no relief in symptoms after fusion lead to dynamic fixation technology emerge as the times require. Patients with spinal canal decompression whether need bone fusion or not is still controversial. For the past few years, the operation of simple decompression for LSS obviously decreased, whereas the decompression plus fusion surgery showed sustainable growth. Decompression complicated with fusion was more and more adopted in LSS, in order to reduce the hidden risk of spinal instability and deformity. Although decompressive operation has determinate effect, now it is still unclear if the therapeutic effect of decompression complicated with fusion is better than simple decompression. This article reviews the current studies to explore whether decompression plus bone fusion is applicable for LSS. To further explore the best choice of surgical treatment for LSS, we focused on evidence-based therapeutic options. Copyright© 2017 by the China Journal of Orthopaedics and Traumatology Press.

    We reported the 18 patients which underwent surgical exploration and reviewed these CT findings. Method All CT scans were obtained on Somatom II, high resolution CT scanner, with the patient in the supine position. A lateral localizer image (Topogram) was used to select the appropriate intervertebral disk space. The slice thickness was 4 mm. Results 1) CT findings in lumbar degenerative diseases include bony canal stenosis (central canal stenosis, narrowed lateral recess), soft tissue abnormalities (herniated nucleus pulposus, bulging annulus, hypertrophy and/or ossification of ligamentum flavum, no delineation of nerve root in lateral recess), and spinal instability (spondylolisthesis, vacuum phenomenon). 2) The above three factors contribute to narrowing of spinal canal. 3) No delineation of nerve root or soft tissue replacement of epidural fat in lateral recess suggests that the nerve root may be compressed by some factors. 4) Herniated nucleus pulposus may cause nerve root compression with or without canal stenosis. Conclusion This study revealed that the CT findings correlated closely with the surgical findings and the site of nerve root compression could be determined.
