    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.

    The uncommon variant of degenerative hip joint disease, termed rapidly progressive osteoarthritis, and highlighted by severe joint space loss and osteochondral disintegration, is well established. We present a similar unusual subset in the lumbar spine termed destructive discovertebral degenerative disease (DDDD) with radiological features of vertebral malalignment, severe disc resorption, and "bone sand" formation secondary to vertebral fragmentation. Co-existing metabolic bone disease is likely to promote the development of DDDD of the lumbar spine, which presents with back pain and sciatica due to nerve root compression by the "bone sand" in the epidural space. MRI and CT play a complimentary role in making the diagnosis.

    The present study aimed to evaluate the early effects of interspinous spacers on lumbar degenerative disease. The clinical outcomes of 23 patients with lumbar degenerative disease, treated using interspinous spacer implantation alone or combined with posterior lumbar fusion, were retrospectively studied and assessed with a visual analogue scale (VAS) and the Oswestry Disability Index (ODI). Pre-operative and post-operative interspinous distance, disc space height, foraminal width and height and segmental lordosis were determined. The early effects and complications associated with the interspinous spacers were recorded. The surgical procedures performed with the in-space treatment were easy and minimally invasive. The VAS scores and ODI were improved post-operatively compared with pre-operatively. Significant changes in the interspinous distance, disc space height, foraminal width and height and segmental lordosis were noted. In-space treatment for degenerative lumbar disease is easy and safe, with good early effects. The in-space system provides an alternative treatment for lumbar degenerative disease.

    In the last 25 years, scientific research has brought about drastic changes in the concept of low back pain and its management. Most imaging findings, including degenerative changes, reflect anatomic peculiarities or the normal aging process and turn out to be clinically irrelevant; imaging tests have proven useful only when systemic disease is suspected or when surgery is indicated for persistent spinal cord or nerve root compression. The radiologic report should indicate the key points of nerve compression, bypassing inconsequential findings. Many treatments have proven inefficacious, and some have proven counterproductive, but they continue to be prescribed because patients want them and there are financial incentives for doing them. Following the guidelines that have proven effective for clinical management improves clinical outcomes, reduces iatrogenic complications, and decreases unjustified and wasteful healthcare expenditures.

    One of the most common indications for performing magnetic resonance (MR) imaging of the lumbar spine is the symptom complex thought to originate as a result of degenerative disk disease. MR imaging, which has emerged as perhaps the modality of choice for imaging degenerative disk disease, can readily demonstrate disk pathology, degenerative endplate changes, facet and ligamentous hypertrophic changes, and the sequelae of instability. Its role in terms of predicting natural history of low back pain, identifying causality, or offering prognostic information is unclear. As available modalities for imaging the spine have progressed from radiography, myelography, and computed tomography to MR imaging, there have also been advances in spine surgery for degenerative disk disease. These advances are described in a temporal context for historical purposes with a focus on MR imaging's history and current state. (orig.)

    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{sup 2} in the femoral neck, while for controls the corresponding figures were 0.989g/cm{sup 2} and 0.765g/cm{sup 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 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.

    Full Text Available There have been few studies comparing the clinical and radiographic outcomes between the Dynesys dynamic stabilization system and posterior lumbar interbody fusion (PLIF. The objective of this study is to compare the clinical and radiographic outcomes of Dynesys and PLIF for lumbar degenerative disease.Of 96 patients with lumbar degenerative disease included in this retrospectively analysis, 46 were treated with the Dynesys system and 50 underwent PLIF from July 2008 to March 2011. Clinical and radiographic outcomes were evaluated. We also evaluated the occurrence of radiographic and symptomatic adjacent segment degeneration (ASD.The mean follow-up time in the Dynesys group was 53.6 ± 5.3 months, while that in the PLIF group was 55.2 ± 6.8 months. At the final follow-up, the Oswestry disability index and visual analogue scale score were significantly improved in both groups. The range of motion (ROM of stabilized segments in Dynesys group decreased from 7.1 ± 2.2° to 4.9 ± 2.2° (P < 0.05, while that of in PLIF group decreased from 7.3 ± 2.3° to 0° (P < 0.05. The ROM of the upper segments increased significantly in both groups at the final follow-up, the ROM was higher in the PLIF group. There were significantly more radiographic ASDs in the PLIF group than in the Dynesys group. The incidence of complications was comparable between groups.Both Dynesys and PLIF can improve the clinical outcomes for lumbar degenerative disease. Compared to PLIF, Dynesys stabilization partially preserves the ROM of the stabilized segments, limits hypermobility in the upper adjacent segment, and may prevent the occurrence of ASD.

    Full Text Available BACKGROUND: To evaluate by MRI intervertebral disc degeneration in patients with lumbar degenerative disease using the Pfirrmann grading system and to determine whether Modic changes correlated with the Pfirrmann grades and modified Pfirrmann grades of disc degeneration. METHODS: The clinical data of 108 surgical patients with lumbar degenerative disease were reviewed and their preoperative MR images were analyzed. Disc degeneration was evaluated using the Pfirrmann grading system. Patients were followed up and low back pain was evaluated using the visual analog scale (VAS and the effect of back pain on the daily quality of life was assessed using Oswestry disability index (ODI. RESULTS: Forty-four cases had normal anatomical appearance (Modic type 0 and their Pfirrmann grades were 3.77±0.480 and their modified Pfirrmann grades were of 5.81±1.006. Twenty-seven cases had Modic type I changes and their Pfirrmann grades were 4.79±0.557 and their modified Pfirrmann grades were 7.00±0.832. Thirty-six cases exhibited Modic type II changes and their Pfirrmann grades and modified Pfirrmann grades were 4.11±0.398 and 6.64±0.867, respectively. One case had Modic type III changes. Kruskal-Wallis test revealed significant difference in modified Pfirrmann grade among Modic type 0, I and II changes (P0.05. Binary regression analysis showed that Modic changes correlated most strongly with disc degeneration. Follow up studies indicated that the VAS and ODI scores were markedly improved postoperatively. However, no difference was noted in VAS and ODI scores among patients with different Modic types. CONCLUSION: Modic changes correlate with the Pfirrmann and modified Pfirrmann grades of disc degeneration in lumbar degenerative disease. There is no significant correlation between Modic types and surgical outcomes.

    Objective. Signal intensity changes in lumbar pedicles, similar to those described in vertebral body endplates adjacent to degenerated discs, have been described as an ancillary sign of spondylolysis on MRI. The purpose of this study was to determine whether pedicle marrow signal intensity changes also occur in association with facet degenerative joint disease.Design. Eighty-nine lumbar spine MRI examinations without spondylolysis were reviewed for marrow signal intensity changes in pedicles and vertebral bodies as well as for facet degenerative joint disease.Results. Five percent (46/890) of lumbar pedicles in 23 patients had marrow signal intensity changes. Ninety-one percent (42/46) of the abnormal pedicles had adjacent degenerative joint disease of the facets, while only 21% (189/890) of normal pedicles had adjacent facet degenerative joint disease (p<0.001). Eighty-nine percent (41/46) of the pedicles with marrow signal intensity changes had adjacent degenerative disc disease.Conclusions. Pedicle marrow signal intensity changes are not a specific sign of spondylolysis; they are commonly seen with adjacent facet degenerative joint disease in the absence of spondylolysis. Pedicle marrow signal intensity changes are probably a response to abnormal stresses related to abnormal motion or loading caused by the degenerative changes in the spinal segment. (orig.)

    Pedicle screw and rod instrumentation has become the preferred technique for performing stabilization and fusion in the surgical treatment of lumbar spine degenerative disease. Rigid fixation leads to high fusion rates but may also contribute to stress shielding and adjacent segment degeneration. Thus, the use of semirigid rods made of polyetheretherketone (PEEK) has been proposed. Although the PEEK rods biomechanical properties, such as anterior load sharing properties, have been shown, there are few clinical studies evaluating their application in the lumbar spine surgical treatment. This study examined a retrospective cohort of patients who underwent posterior lumbar fusion for degenerative disease using PEEK rods, in order to evaluate the clinical and radiological outcomes and the incidence of complications.

    A patient is presented in whom a focal reduction in marrow activity in the lumbar spine on both leucocyte and nanocolloid marrow scintigraphy was subsequently shown to be due to fatty infiltration of marrow in association with disc degeneration. Degenerative disease in the lumbar spine has not been previously described as a cause of abnormal bone marrow distribution by such means and needs to be distinguished from a more serious pathology, such as malignant infiltration and vertebral infection, which it may mimic. In a retrospective review of 33 nanocolloid bone marrow and 117 leucocyte scintigrams, 8 showed a degree of reduced marrow activity in the lumbar spine consistent with that caused by degenerative changes.

    Parallel imaging techniques such as GRAPPA have been introduced to optimize image quality and acquisition time. For spinal imaging in a clinical setting no data exist on the equivalency of conventional and parallel imaging techniques. The purpose of this study was to determine whether T1- and T2-weighted GRAPPA sequences are equivalent to conventional sequences for the evaluation of degenerative lumbar spine disease in terms of image quality and artefacts. In patients with clinically suspected degenerative lumbar spine disease two neuroradiologists independently compared sagittal GRAPPA (acceleration factor 2, time reduction approximately 50%) and non-GRAPPA images (25 patients) and transverse GRAPPA (acceleration factor 2, time reduction approximately 50%) and non-GRAPPA images (23 lumbar segments in six patients). Comparative analyses included the minimal diameter of the spinal canal, disc abnormalities, foraminal stenosis, facet joint degeneration, lateral recess, nerve root compression and osteochondrotic vertebral and endplate changes. Image inhomogeneity was evaluated by comparing the nonuniformity in the two techniques. Image quality was assessed by grading the delineation of pathoanatomical structures. Motion and aliasing artefacts were classified from grade 1 (severe) to grade 5 (absent). There was no significant difference between GRAPPA and non-accelerated MRI in the evaluation of degenerative lumbar spine disease (P > 0.05), and there was no difference in the delineation of pathoanatomical structures. For inhomogeneity there was a trend in favour of the conventional sequences. No significant artefacts were observed with either technique. The GRAPPA technique can be used effectively to reduce scanning time in patients with degenerative lumbar spine disease while preserving image quality. (orig.)

    Minimally invasive unilateral pedicle screw fixation for the treatment of degenerative lumbar diseases has won the support of many surgeons. However, few data are available regarding clinical research on unilateral pedicle screw fixation associated with minimally invasive techniques for the treatment of lumbar spinal diseases. The purpose of this study was to evaluate clinical outcomes in a selected series of patients with lumbar degenerative diseases treated with minimally invasive unilateral vs classic bilateral pedicle screw fixation and lumbar interbody fusion. Patients in the unilateral group (n=43) underwent minimally invasive unilateral pedicle screw fixation with the Quadrant system (Medtronic, Memphis, Tennessee). The bilateral group (n=42) underwent bilateral instrumentation via the classic approach. Visual analog scale pain scores, Oswestry Disability Index scores, fusion rate, operative time, blood loss, and complications were analyzed. Mean operative time was 75 minutes in the unilateral group and 95 minutes in the bilateral group. Mean blood loss was 220 mL in the unilateral group and 450 mL in the bilateral group. Mean postoperative visual analog scale pain score was 3.10±0.16 in the unilateral group and 3.30±1.10 in the bilateral group. Mean postoperative Oswestry Disability Index score was 15.67±2.3 in the unilateral group and 14.93±2.6 in the bilateral group. Successful fusion was achieved in 92.34% of patients in the unilateral group and 93.56% of patients in the bilateral group. Minimally invasive unilateral pedicle screw fixation is an effective and reliable option for the surgical treatment of lumbar degenerative disease. It causes less blood loss, requires less operative time, and has a fusion rate comparable with that of conventional bilateral fixation. Copyright 2013, SLACK Incorporated.

    There is increasing interest in the use of pelvic indices to evaluate sagittal balance and predict outcomes in patients with spinal disease. Conventional posterior lumbar fusion techniques may adversely affect lumbar lordosis and spinal balance. Minimally invasive fusion of the lumbar spine is rapidly becoming a mainstay of treatment of lumbar degenerative disc disease. To our knowledge there are no studies evaluating the effect of extreme lateral interbody fusion (XLIF) on pelvic indices. Hence, our aim was to study the effect of XLIF on pelvic indices related to sagittal balance, and report the results of a prospective longitudinal clinical study and retrospective radiographic analyses of patients undergoing XLIF in a single centre between January 2009 and July 2011. Clinical outcomes are reported for 30 patients and the retrospective analyses of radiographic data is reported for 22 of these patients to assess global and segmental lumbar lordosis and pelvic indices. Effect of XLIF on the correction of scoliotic deformity was assessed in 15 patients in this series. A significant improvement was seen in the visual analogue scale score, the Oswestry Disability Index and the Short Form-36 at 2months and 6months (p0.2). Global lumbar lordosis was not affected by XLIF (p>0.4). XLIF significantly increased segmental lumbar lordosis by 3.3° (psagittal balance. Long-term follow-up with a larger cohort will be required to further evaluate the effects of XLIF on sagittal balance.

    Full Text Available Mechanical articulated device to replace intervertebral disc as a treatment for low back pain secondary to disc degeneration has emerged as a promising tool for selected patients. The potential advantages are prevention of adjacent segment degeneration, maintenance of mobility as well as avoidance of all the complications associated with fusion. The short-term results have been comparable to that of fusion, a few mid-term results have shown mixed outcome, but information on long-term results and performance are not available at present. The rationale for lumbar disc arthroplasty, indications, contraindications, the various artificial devices in the market and the concepts intrinsic to each of them, basic technique of insertion, complications are discussed and a brief summary of our experience with one of the devices is presented.

    Background Bilateral transpedicular screw fixation in conjunction with interbody fusion is widely used to treat lumbar degenerative diseases; however,there are some disadvantages of using this fixation system.This study comparatively analyzes the results of unilateral and bilateral pedicle screw fixation combined with transforaminal lumbar interbody fusion (TLIF) for one-level lumbar degenerative diseases.Methods Sixty-six cases with one-level lumbar degenerative diseases were studied.The patients were divided according to surgical approach into a unilateral group (Group A) and a bilateral group (Group B).The patients were evaluated for pain by visual analog scale (VAS) and Oswestry Disability Index (ODI).Operating time,blood loss,duration of hospitalization,and complication rate were also evaluated.Patients were examined at 1,3,6,and 12 months postoperatively and every year thereafter.Results Group A patients' average preoperative VAS and ODI scores were 7.03 ± 0.98 and (64.22±6.38)%,respectively,significantly decreased to 2.91 ± 0.88 and (14.42±2.08)%,respectively,at the last follow-up (P =0.000).In Group B,the average preoperative VAS and ODI scores were 6.79±0.86 and (63.22±4.70)%,respectively,significantly decreased to 3.12±0.96 and (14.62±2.08)%,respectively,at the last follow-up (P=0.000).No significant difference in the duration of hospitalization was found between groups.Operating time and blood loss of (125.9±13.0) minutes and (211.4±28.3) ml,respectively,in Group A were significantly less than (165.2±15.3) minutes and (258.6±18.3) ml,respectively,in Group B (P=-0.000).All patients achieved good bone union and had no pseudarthrosis at the last follow-up.Conclusions There are no clinical differences between unilateral and bilateral pedicle screw fixation combined with TLIF for one-level lumbar degenerative diseases.Unilateral fixation reduces operating time,bleeding,and cost of hospitalization.

    Background The Dynamic Interspinous Assisted Motion (DIAM) system was designed to stabilize degenerative spinal segments without fusion surgery, maintain segment motion and prevent adjacent segment degeneration. The aim of thisstudy was to investigate clinical efficacy of the DIAM system in treatment of degenerative lumbar disease in China.Methods Eight cases of lumbar vertebral instability were treated with the DIAM system at Peking Union MedicalCollege Hospital from June 2006 to January 2008. There were 6 female and 2 male subjects with a mean age of 46.9years and a range of 40-52 years. Radiographs and scores on outcome measures included the visual analogue scale (VAS) for pain and the Oswestry disability index (ODI). These scores were recorded before surgery and after surgery at intervals of 3-month, 6-month, 1-year and the final follow-up visit.Results The follow-up time ranged from 12-31 months, with an average of 20.6 months. There were significant differences between preoperative and postoperative scores at each follow-up evaluation (P <0.05). However, there was no significant difference between each postoperative follow-up score (P >0.05). There were significant differences between preoperative and postoperative L4-5 segment activity at each time interval (P <0.05), but no obvious difference was found within each postoperative follow-up evaluation (P >0.05). The ODI and VAS score improvements were directly correlated with segment activity (r >0.7, P <0.05).Conclusions The DIAM system appears to be a useful and effective treatment in the surgical management of degenerative lumbar disease in certain patients. However, long-term follow-up is needed to evaluate the clinical outcomes of the device.

    Full Text Available Fusion and rigid instrumentation have been currently the mainstay for the surgical treatment of degenerative diseases of the spine over the last 4 decades. In all over the world the common experience was formed about fusion surgery. Satisfactory results of lumbar spinal fusion appeared completely incompatible and unfavorable within years. Rigid spinal implants along with fusion cause increased stresses of the adjacent segments and have some important disadvantages such as donor site morbidity including pain, wound problems, infections because of longer operating time, pseudarthrosis, and fatigue failure of implants. Alternative spinal implants were developed with time on unsatisfactory outcomes of rigid internal fixation along with fusion. Motion preservation devices which include both anterior and posterior dynamic stabilization are designed and used especially in the last two decades. This paper evaluates the dynamic stabilization of the lumbar spine and talks about chronologically some novel dynamic stabilization devices and thier efficacies.

    Magnetic resonance imaging was performed in 400 patients with degenerative disc disease. Signal changes and their sites in the vertebral body were classified and referred to narrowing of the intervertebral disc space. MR findings were compared with those of plain roentgenograms of the lumbar spine. Signal changes in the vertebral body were noted in 83 cases (102 vertebral bodies). Low-intensity abnormality on both T1- and T2-weighted images (WI) was the most common finding, and was most frequently seen at the end plate and/or the angle. These changes were correlated with narrowing of the disc space and osteosclerosis on the plain roentgenogram of the lumbar spine. Signal changes occasionally occurred in the inner region of the vertebral body, and these lesions tended to show a high-intensity abnormality on T1-WI. We conclude that signal changes in degenerative disc disease are not specific, but are sometimes difficult to distinguish from the signal changes in other conditions such as spinal tumor or bone marrow disorder.

    Three-dimensional (3-D) magnetic resonance (MR) images obtained from 10 patients with lumbar degenerative diseases were retrospectively reviewed to determine how far 3-D MR imaging is capable of demonstrating nerve roots. In 8 of the 10 patients, the area up to the dorsal root ganglion was visualized on 3-D MR images. Thus, it is capable of detecting a wide area of nerve roots, thereby allowing the determination of running of nerve root, and size and location of dorsal root ganglion. In delineating the area from the dural canal to root cyst, 3-D MR imaging was equal to conventional myelography. The former was superior to the latter in detecting the positional relation between the degenerative intervertebral disc and the nerve root, and herniation-compressed root cyst. In 3 of 9 patients who presented with root symptoms, disturbed nerve roots were of high signal on 3-D MR images. This may suggest that it has the potential for selectively detecting root nerves associated with clinical manifestations. (N.K.).

    A large number of interspinous process devices (IPD) have been recently introduced to the lumbar spine market as an alternative to conventional decompressive surgery in managing symptomatic lumbar spinal pathology, especially in the older population. Despite the fact that they are composed of a wide range of different materials including titanium, polyetheretherketone, and elastomeric compounds, the aim of these devices is to unload spine, restoring foraminal height, and stabilize the spine by distracting the spinous processes. Although the initial reports represented the IPD as a safe, effective, and minimally invasive surgical alternative for relief of neurological symptoms in patients with low back degenerative diseases, recent studies have demonstrated less impressive clinical results and higher rate of failure than initially reported. The purpose of this paper is to provide a comprehensive overview on interspinous implants, their mechanisms of action, safety, cost, and effectiveness in the treatment of lumbar stenosis and degenerative disc diseases.

    Degenerative conditions of the lumbar spine are extremely common. Ninety percent of people over the age of 60 years have degenerative change on imaging; however, only a small minority of people will require spine surgery (Hicks et al. Spine (Phila Pa 1976) 34(12):1301-1306, 2009). This minority, however, constitutes a core element of spinal surgery practice. Whilst the patient outcomes from spinal surgeries have improved in recent years, some patients will remain with pain and disability despite technically successful surgery. Advances in regenerative medicine and stem cell therapies, particularly the use of mesenchymal stem cells and allogeneic mesenchymal precursor cells, have led to numerous clinical trials utilising these cell-based therapies to treat degenerative spinal conditions. Through cartilage formation and disc regeneration, fusion enhancement or via modification of pain pathways, stem cells are well suited to enhance spinal surgery practice. This review will focus on the outcomes of lumbar spinal procedures and the role of stem cells in the treatment of degenerative lumbar conditions to enhance clinical practice. The current status of clinical trials utilising stem cell therapies will be discussed, providing clinicians with an overview of the various cell-based treatments likely to be available to patients in the near future.

    A retrospective and radiological study of degenerative spinal diseases. To explore the changes in spinopelvic sagittal alignment after lumbar instrumentation and fusion of degenerative spinal diseases. Efforts have been paid to clarify the ideal postoperative sagittal profile for degenerative spinal diseases. However, little has been published about the actual changes of sagittal alignment after lumbar lordosis reconstruction. Radiographical analysis of 83 patients with spinal degeneration was performed by measuring sagittal parameters before and after operations. Comparative studies of sagittal parameters between short (1 level) and long (≥ 2 level) instrumentation and fusion were performed. Different variances (Δ) of these sagittal parameters before and after operations were calculated and compared. Correlative study and linear regression were performed to establish the relationship between variances. No significant changes were shown in the short-fusion group postoperatively. In the long-fusion group, postoperative lumbar lordosis (LL) and sacral slope (SS) were significantly increased; pelvic tilt (PT), sagittal vertical axis (SVA), pelvic incidence minus lumbar lordosis, and PT/SS were significantly decreased. Different variances of ΔLL, ΔSS, ΔPT, ΔSVA, Δ(pelvic incidence - LL), and ΔPT/SS were significantly greater in the long-fusion group than the short-fusion group. Close correlations were mainly shown among ΔLL, ΔPT, and ΔSVA. Linear regression equations could be developed (ΔPT = -0.185 × ΔLL - 7.299 and ΔSVA = -0.152ΔLL - 1.145). In degenerative spinal diseases, long instrumentation and fusion (≥ 2 levels) provides more efficient LL reconstruction. PT, SS, and SVA improve corresponding to LL in a linear regression model. Linear regression equations could be developed and used to predict PT and SVA change after long instrumentation and fusion for LL reconstruction.

    Background Transforaminal lumbar interbody fusion (TLIF) through a minimally invasive approach (mTLIF) was introduced to reduce soft tissue injury and speed recovery.Studies with small numbers of patients have been carried out,comparing mTLIF with traditional open TLIF (oTLIF),but inconsistent outcomes were reported.Methods We conducted a meta-analysis to evaluate the effectiveness of mTLIF and oTLIF in the treatment of degenerative lumbar disease.We searched PubMed,Embase and Cochrane Database of Systematic Reviews in March 2013 for studies directly comparing mTLIF and oTLIF.Patient characteristics,interventions,surgical-related messages,early recovery parameters,long-term clinical outcomes,and complications were extracted and relevant results were pooled.Results Twelve cohort studies with a total of 830 patients were identified.No significant difference regarding average operating time was observed when comparing mTLIF group with oTLIF group (-0.35 minute,95% confidence interval (C/):-20.82 to 20.13 minutes).Intraoperative blood loss (-232.91 ml,95% CI:-322.48 to-143.33 ml) and postoperative drainage (-111.24.ml,95% CI:-177.43 to-45.05 ml) were significantly lower in the mTLIF group.A shorter hospital stay by about two days was observed in patients who underwent mTLIF (-2.11 days,95% CI:-2.76 to-1.45 days).With regard to long-term clinical outcomes,no significant difference in visual analog scale score (-0.25,95% CI:-0.63 to 0.13) was observed; however,there was a slight improvement in Oswestry Disability Index (-1.42,95% CI:-2.79 to-0.04) during a minimum of 1-year follow-up between the two groups.The incidence of complications did not differ significantly between the procedures (RR=1.06,95% CI:0.7 to 1.59).Reoperation was more common in patients in mTLIF group than in oTLIF group (5% vs.2.9%),but this difference was not significant (RR=1.62,95% CI:0.75 to 3.51).Conclusion Current evidence suggests that,compared with traditional open surgery

    Interbody fusion techniques have been promoted as an adjunct to lumbar fusion procedures in an effort to enhance fusion rates and potentially improve clinical outcome. The medical evidence continues to suggest that interbody techniques are associated with higher fusion rates compared with posterolateral lumbar fusion (PLF) in patients with degenerative spondylolisthesis who demonstrate preoperative instability. There is no conclusive evidence demonstrating improved clinical or radiographic outcomes based on the different interbody fusion techniques. The addition of a PLF when posterior or anterior interbody lumbar fusion is performed remains an option, although due to increased cost and complications, it is not recommended. No substantial clinical benefit has been demonstrated when a PLF is included with an interbody fusion. For lumbar degenerative disc disease without instability, there is moderate evidence that the standalone anterior lumbar interbody fusion (ALIF) has better clinical outcomes than the ALIF plus instrumented, open PLF. With regard to type of interbody spacer used, frozen allograft is associated with lower pseudarthrosis rates compared with freeze-dried allograft; however, this was not associated with a difference in clinical outcome.

    We report on the use and performance of an objective measure of functional impairment, the timed up and go (TUG) test, in clinical practice for patients with lumbar degenerative disc disease (DDD). We illustrate nine representative patients with lumbar DDD, who were selected from an ongoing prospective study, to report our clinical experience with the TUG test. In addition, a preliminary sample of 30 non-selected consecutive patients is presented. The following parameters were assessed preoperatively, and 3 days and 6 weeks postoperatively: back and leg pain using the visual analogue scale (VAS); functional impairment using the Oswestry disability index (ODI) and Roland-Morris disability index (RMDI); health-related quality of life using the EuroQol 5D (EQ5D) and Short-Form 12 (SF-12). The TUG test results improved by 2.6 and 5.4s after 3 days and 6 weeks compared to the baseline assessment. The mean VAS for back and leg pain decreased by 2.3 and 5.3, respectively, after 3 days, and by 2.7 and 4.6 after 6 weeks. The mean RMDI and ODI decreased by 3.4 and 23.3, respectively, after 3 days, and by 7.0 and 28.0 after 6 weeks. The mean EQ5D increased by 0.38 after 3 days and 0.358 after 6 weeks. The mean SF-12 mental component scale decreased by 0.2 after 3 days and increased by 5.6 after 6 weeks, whereas the mean SF-12 physical component scale increased by 6.4 after 3 days and by 9.8 after 6 weeks. The TUG test proved to be a useful, easy to use tool that could add a new, objective dimension to the armamentarium of clinical tests for the diagnosis and management of DDD. From our preliminary experience, we conclude that the TUG test accurately reflects a patient's objective functional impairment before and after surgery. Copyright © 2015 Elsevier Ltd.

    Assessment of functional patient-reported outcome following lumbar spinal fusion continues to be essential for comparing the effectiveness of different treatments for patients presenting with degenerative disease of the lumbar spine. When assessing functional outcome in patients being treated with lumbar spinal fusion, a reliable, valid, and responsive outcomes instrument such as the Oswestry Disability Index should be used. The SF-36 and the SF-12 have emerged as dominant measures of general health-related quality of life. Research has established the minimum clinically important difference for major functional outcomes measures, and this should be considered when assessing clinical outcome. The results of recent studies suggest that a patient's pretreatment psychological state is a major independent variable that affects the ability to detect change in functional outcome.

    Systematic review with meta-analysis. To (1) evaluate long-term patient-centered clinical outcomes after lumbar arthrodesis with or without decompression for lumbar spondylosis (LS); and (2) compare these outcomes with those of alternative treatments, including nonsurgical and surgical which maintain mobility of the lumbar spine. The effective treatment of LS is a complex clinical and economic concern for patients and health care providers. (1) randomized controlled clinical trials (RCTs) comparing treatment effects of lumbar arthrodesis with other interventions; (2) participants: skeletally mature adults with lumbar degenerative disk disease. Ovid MEDLINE, Embase, the Cochrane Library, and others. All years through February of 2013 were included. Patient-centered clinical outcomes before treatment, at 12, 24, or >24 months of follow-up, and rate of complications and additional surgical treatment were collected. A meta-analysis was performed to evaluate pooled treatment effects. The GRADE approach was applied to evaluate the level of evidence. The review included 38 studies of 5738 participants. All studies showed strong or at least moderate treatment effects of lumbar arthrodesis at 12, 24, and 48-72 months of follow-up. The level of evidence was moderate at 12 and 24 months, and low at 48-72 months. The pooled long-term treatment effect of lumbar arthrodesis exceeded those of: nonsurgical treatment (Pinferiority versus arthroplasty at 12 and 24 months of follow-up (P<0.001), but not after 24 months postoperative. This review indicates that surgical stabilization of the lumbar spine is an effective treatment for LS; in particular, for patients with severe chronic low back pain that has been resistant to ≥3 months of conservative therapy.

    Retrospective analysis of the spino-pelvic alignment in a population of 85 patients with a lumbar degenerative disease. Several previous publications reported the analysis of spino-pelvic alignment in the normal and low back pain population. Data suggested that patients with lumbar diseases have variations of sagittal alignment such as less distal lordosis, more proximal lumbar lordosis and a more vertical sacrum. Nevertheless most of these variations have been reported without reference to the pelvis shape which is well-known to strongly influence spino-pelvic alignment. The objective of this study was to analyse spino-pelvic parameters, including pelvis shape, in a population of 85 patients with a lumbar degenerative disease and compare these patients with a control group of normal volunteers. We analysed three different lumbar degenerative diseases: disc herniation (DH), n = 25; degenerative disc disease (DDD), n = 32; degenerative spondylolisthesis (DSPL), n = 28. Spino-pelvic alignment was analysed pre-operatively on full spine radiographs. Spino-pelvic parameters were measured as following: pelvic incidence, sacral slope, pelvic tilt, lumbar lordosis, thoracic kyphosis, spino-sacral angle and positioning of C7 plumb line. For each group of patients the sagittal profile was compared with a control population of 154 asymptomatic adults that was the subject of a previous study. In order to understand variations of spino-pelvic parameters in the patients' population a stratification (matching) according to the pelvic incidence was done between the control group and each group of patients. Concerning first the pelvis shape, patients with DH and those with DDD demonstrated to have a mean pelvic incidence equal to 49.8 degrees and 51.6 degrees, respectively, versus 52 degrees for the control group (no significant difference). Only young patients, less than 45 years old, with a disc disease (DH or DDD) demonstrated to have a pelvic incidence significantly lower (48

    Full Text Available OBJECTIVE: The purpose of this study was to analyze the clinical features and prognostic factors of surgical outcome of foot drop caused by lumbar degenerative disease and put forward the clinical stage. METHODS: We retrospectively reviewed 135 patients with foot drop due to lumbar degenerative disease. The clinical features and mechanism were analyzed. Age, sex, duration of palsy, preoperative muscle strength of tibialis anterior (TA, sensation defect of affected lower limb, affected foot, diagnosis and compressed nerve roots were recorded and compared with surgical outcome. RESULTS: Foot drop was observed in 8.1% of all inpatients of lumbar degenerative disease. L5 nerve root compression was observed in 126 of all 135 patients (93.3%. Single, double and triple roots compression was observed respectively in 43, 83, and 9 patients (31.9%, 61.5%, and 6.6%. But there was no significant relationship between preoperative muscle strength of TA and the number of compressed roots. The muscle strength of TA was improved in 113 (83.7% patients after surgery, but it reached to >=4 in only 21 (15.6% patients. Improvement of the muscle strength of TA was almost stable at the 6-month follow-up. At the last follow-up, the muscle strength of TA was 1, 2, 3, 4, 5 respectively in 28, 24, 62, 13, 8 patients. Multivariate logistic regression showed duration of palsy (p=0.0360, OR=2.543, preoperative muscle strength of TA (p=0.0064, OR=5.528 and age (p=0.0309, OR=3.208 were factors that influenced recovery following an operation. CONCLUSIONS: L5 nerve root was most frequently affected. The muscle strength of TA improved in most patients after surgery, but few patients can get a good recovery from foot drop. Patients of shorter duration of palsy, better preoperative muscle strength of TA and younger age showed a better surgical outcome.

    Retrospective study of a consecutive patient series. To review the radiographic classification of patients with sagittal imbalance due to lumbar degenerative kyphosis (LDK) and to determine correlation between thoracic and lumbar curve. Lumbar degenerative kyphosis is one of the common spinal deformities in Asian countries, especially Korea and Japan. However, there have been few studies regarding the classification and treatment of this disease. Seventy-eight patients with LDK were analyzed and classified according to the standing lateral whole spine findings. Total lumbar lordosis (L1-S1), thoracic kyphosis (T5-T12), sacral slope, thoracolumbar angle (T11-L1), and sagittal vertical axis (SVA) were measured on the lateral view of the whole spine. Spinal curve deformities were classified into 2 groups according to the thoracolumbar (T-L) junction angle: flat or lordotic angle (Group 1; N = 53) and kyphotic angle (Group 2; N = 25). In Group 1, significant correlations between the thoracic and lumbar curves (r = 0.772, P sagittal thoracic compensated group. In contrast, In Group 2, no correlation was found between the thoracic and lumbar curves in the decompensated group (r = 0.179, P = 0.391), but we found a significant correlation between lordosis and sacral slope (r = 0.442, P = 0.027). By this result, Group 2 was classified as sagittal thoracic decompensated group. There was significant difference in SVA between 2 groups (P = 0.020). The angle of the thoracolumbar junction is an important parameter in determining whether a sagittal thoracic compensatory mechanism exists in LDK. We assumed that existence of a compensatory mechanism in the proximal spine is central to the determination of the fusion levels in the treatment of LDK.

    To assess the radiographic results in patients who underwent transforaminal lumbar interbody fusion (TLIF), particularly the changes in segmental lordosis in the fusion segment, whole lumbar lordosis and disc height. Twenty six cases of single-level TLIF in degenerative lumbar diseases were analyzed. The changes in segmental lordosis, whole lumbar lordosis, and disc height were evaluated before surgery, after surgery and at the final follow-up. The segmental lordosis increased significantly after surgery but decreased at the final follow-up. Compared to the preoperative values, the segmental lordosis did not change significantly at the final follow-up. Whole lumbar lordosis at the final follow-up was significantly higher than the preoperative values. The disc height was significantly higher in after surgery than before surgery (p = 0.000) and the disc height alter surgery and at the final follow-up was similar. When performing TLIF, careful surgical techniques and attention are needed to restore and maintain the segmental lordosis at the fusion level.

    Fusion procedures are an accepted and successful management strategy to alleviate pain and/or neurological symptoms associated with degenerative disease of the lumbar spine. In 2005, the first version of the "Guidelines for the performance of fusion procedures for degenerative disease of the lumbar spine" was published in the Journal of Neurosurgery: Spine. In an effort to incorporate evidence obtained since the original publication of these guidelines, an expert panel of neurosurgical and orthopedic spine specialists was convened in 2009. Topics reviewed were essentially identical to the original publication. Selected manuscripts from the first iteration of these guidelines as well as relevant publications between 2005 through 2011 were reviewed. Several modifications to the methodology of guideline development were adopted for the current update. In contrast to the 2005 guidelines, a 5-tiered level of evidence strategy was employed, primarily allowing a distinction between lower levels of evidence. The qualitative descriptors (standards/guidelines/options) used in the 2005 recommendations were abandoned and replaced with grades to reflect the strength of medical evidence supporting the recommendation. Recommendations that conflicted with the original publication, if present, were highlighted at the beginning of each chapter. As with the original guideline publication, the intent of this update is to provide a foundation from which an appropriate treatment strategy can be formulated.

    Full Text Available Introduction. Outcome evaluation is an important aspect of the treatment of patients with degenerative lumbar disease. We evaluated the usefulness of the Core Outcome Measures Index (COMI in assessing people affected by degenerative lumbar disease in daily clinical practice. Methods. We evaluated 221 patients who had completed preoperatively and 2 years after surgery VAS pain, Short Form-36 (SF-36, Oswestry Disability Index (ODI and COMI. We calculated the change of scores and its sensitivity to change. The internal consistency of the COMI items and the correlation between the COMI scores and the scores of the other measurements were assessed. Results. Statistically significant differences were observed between the mean scores of the preoperative and 2 years questionnaires for nearly all measurements. COMI showed a good internal consistency, except for the preoperative pain subscale. The sensitivity to change was high for the total COMI and its pain and well-being subscales and moderate for the rest. The COMI demonstrated strong correlation with the other measurements. Conclusions. The COMI is a useful tool for assessing the patient-based outcome in the studied population. Given its simplicity, good correlation with the SF-36 and ODI and its good sensitivity to change, it could replace more cumbersome instruments in daily clinical practice.

    Full Text Available Produced spondilometric measurements of the lumbosacral spine is normal (20 cases and in patients with spinal cord injury and degenerative-dystrophic diseases of the spine (43 cases. The width of the facet joint space joints on both sides, its relation to the longitudinal axis of the body in degrees and another on the same level were studied. The width of the facet joint space at the lumbosacral level of 3.5–4.0 mm, the area of the intervertebral foramen varies from 96–132 mm2. Among the changes in the parameters of the vertebral-motor segment can distinguish moderate, marked and significant extent that is important in determining the amount of the alleged operation.

    Interspinous distraction devices provide an effective treatment for patients suffering from lumbar spinal stenosis and/or degenerative disk disease. The aim of this multicenter study was the prospective evaluation of patients treated for symptomatic lumbar spinal stenosis with interspinous process decompression (IPD) implants compared with a population of patients managed with conservative treatment. 542 patients affected by symptomatic lumbar spine degenerative disease were enrolled in a controlled trial. 422 patients underwent surgical treatment consisting of X-STOP device implantation, whereas 120 control cases were managed conservatively. Both patient groups underwent follow-up evaluations at 6, 12, 24, and 36 months using the Zurich Claudication Questionnaire, the Visual Analog Scale score and spinal lumbar X-rays, CT scans and MR imaging. One-year follow-up evaluation revealed positive good results in the 83.5% of patients treated with IPD with respect to 50% of the nonoperative group cases. During the first three years, in 38 out of the 120 control cases, a posterior decompression and/or spinal fixation was performed because of unsatisfactory results of the conservative therapy. In 24 of 422 patients, the IPD device had to be removed, and a decompression and/or pedicle screw fixation was performed because of the worsening of neurological symptoms. Our results support the effectiveness of surgery in patients with stenosis. IPD may offer an effective and less invasive alternative to classical microsurgical posterior decompression in selected patients with spinal stenosis and lumbar degenerative disk diseases.

    Full Text Available Some cases with lumbar degenerative diseases require multi-level fusion surgeries. At our institute, 27 and 4 procedures of 3- and 4-level fusion were performed out of a total 672 posterior lumbar interfusions (PLIFs on patients with lumbar degenerative disease from 2005 to 2010. We present 2 osteoporotic patients who developed proximal vertebral body fracture after 4-level fusion. Both cases presented with gait disability for leg pain by degenerative lumbar scoliosis and canal stenosis at the levels of L1/2-4/5. After 4-level fusion using L1 as the upper instrumented vertebra, proximal vertebral body fractures were found along with the right pedicle fractures of L1 in both cases. One of these patients, aged 82 years, was treated as an outpatient using a hard corset for 24 months, but the fractures were exacerbated over time. In the other patient, posterolateral fusion was extended from Th10 to L5. Both patients can walk alone and have been thoroughly followed up. In both cases, the fracture of the right L1 pedicle might be related to the subsequent fractures and fusion failure. In consideration of multi-level fusion, L1 should be avoided as an upper instrumented vertebra to prevent junctional kyphosis, especially in cases with osteoporosis and flat back posture.

    The clinical benefits and complications of posterior lumbar interbody fusion (PLIF) have been studied over the past 60 years. In recent years, spine surgeons have had the option of treating low back pain caused by degenerative disc disease using PLIF with machined allograft spacers and posterior pedicle fixation. The purpose of this clinical series was to assess the clinical benefits of using a machined PLIF allograft spacer and posterior pedicle fixation to treat degenerative disc disease, both in terms of fusion rates and patient outcomes, and to compare these results with those in previous studies using autograft and metal interbody fusion devices. Results were also compared with results from studies using transverse process fusion. This prospective, nonrandomized clinical series was conducted at 10 US medical centers. Eighty-nine (55 male, 34 female) patients underwent PLIF with a presized, machined allograft spacer and posterior pedicle fixation between January 2000 and April 2003. Their outcomes were compared with outcomes in previous series described in the literature. All patients had experienced at least 6 months of low back pain that had been unresponsive to nonsurgical treatment. Physical examinations were performed before surgery, after surgery, and at 4 follow-up visits (6 weeks, 6 months, 12 months, 24 months). At each interval, we obtained radiographs and patient outcome measures, including SF-36 Bodily Pain Score, visual analog scale pain rating, and Oswestry Disability Index. The primary outcome was fusion results at 12 and 24 months; the secondary outcomes were pain, disability, function/quality of life, and satisfaction. One-level PLIFs were performed in 65 patients, and 2-level PLIFs in 24 patients. Flexion-extension radiographs at 12 and 24 months revealed a 98% fusion rate. Of the 72 patients who reached the 12-month follow-up, 86% reported decreased pain and disability as measured with the Oswestry Disability Index. Decreased pain as measured

    This prospective interventional study carried out at Bangabandhu Sheikh Mujib Medical University and a private hospital in Dhaka, Bangladesh during the period from October 2003 to September 2011. Surgical treatment of degenerative disc disease (DDD) should aim to re-expand the interbody space and stabilize until fusion is complete. The present study conducted to find out the efficacy of using interbody fusion device (Cage) to achieve interbody space re-expansion and fusion in surgical management of DDD. We have performed the interventional study on 53 patients, 42 female and 11 male, with age between 40 to 67 years. All the patients were followed up for 36 to 60 months (average 48 months). Forty seven patients were with spondylolisthesis and 06 with desiccated disc. All subjects were evaluated with regard to immediate and long term complications, radiological fusion and interbody space re-expansion and maintenance. The clinical outcome (pain and disability) was scored by standard pre and postoperative questionnaires. Intrusion, extrusion and migration of the interbody fusion cage were also assessed. Forty seven patients were considered to have satisfactory outcome in at least 36 months follow up. Pseudoarthrosis developed in 04 cases and 06 patients developed complications. In this series posterior lumbar interbody fusion (PLIF) with interbody cage and instrumentation in DDD showed significant fusion rate and maintenance of interbody space. Satisfactory outcome observed in 88.68% cases.

    Abstract The purpose of this study was to explore incidence and risk factors of adjacent segment disease (ASD) following posterior decompression and instrumented fusion for degenerative lumbar disorders, and hope to provide references in decision making and surgical planning for both spinal surgeon and surgically treated patients. By retrieving the medical records from January 2011 to December 2013 in our hospital, 237 patients were retrospectively reviewed. According to the occurrence of ASD at follow up, patients were divided into 2 groups: ASD and N-ASD group. To investigate risk values for the occurrence of ASD, 3 categorized factors were analyzed statistically: Patient characteristics: age, sex, body mass index (BMI), bone mineral density (BMD), duration. Surgical variables: surgical strategy, number of fusion level, surgery segment, surgery time, blood loss, intraoperative superior facet joint violation. Radiographic parameters: preoperative lumbar lordosis, preoperative angular motion at adjacent segment, preoperative adjacent segment disc degeneration, preoperative paraspinal muscle degeneration. Postoperative ASD was developed in 15 of 237 patients (6.3%) at final follow up. There was no statistically significant difference between the 2 groups in patient characteristics of age, sex composition, BMD, duration, while the BMI was higher in ASD group than that in N-ASD group. There was no difference in surgical variables of surgical strategy, number of fusion level, surgery segment, surgery time, blood loss, while intraoperative superior facet joint violation was more common in ASD group than that in N-ASD group. There was no difference in radiographic parameters of preoperative lumbar lordosis, preoperative paraspinal muscle degeneration, while preoperative adjacent segment disc degeneration were more severe in ASD group than that in N-ASD group. The Logistic regression analysis revealed that, BMI >25 kg/m2, preoperative disc degeneration, and superior

    Background 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.Methods 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.Results 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<0.05).Neither anterior nor posterior disc height was significantly changed.Segmental lordosis of L4-L5 and total lordosis were all increased significantly(Topping-off group:t=-2.30 and-2.24,P<0.05;PLIF group:t=-2.76 and-1.83,P<0.01).In the hyperextension and hyperflexion view,Topping-off group's range of motion(ROM)and olisthesis in the L4-L5 segment did not significantly change in flexion,but decreased in extension.In PLIF group,ROM(t=-7.82 and-4.90,P<0.01)and olisthesis(t=-15.67and-18.58,P<0.01)both significantly increased in extension and flexion.Conclusions Compared with single segment PLIF surgery,Topping-off surgery can achieve similar

    To evaluate the influence of epidemiological factors on the outcomes of surgery for degenerative lumbar disease in terms of quality of life, disability and chronic pain. A total of 263 patients who received surgery for degenerative lumbar disease (2005-2008) were included in the study. The epidemiological data collected were age, gender, employment status, and co-morbidity. The SF-36, Oswestry Disability Index (ODI), Core Outcomes Measures Index (COMI), and VAS score for lumbar and sciatic pain were measure before and 2 years after surgery. The correlation between epidemiological data and questionnaire results, as well as any independent prognostic factors, were assessed in the data analysis. The mean age of the patients was 54.0 years (22-86), and 131 were female (49.8%). There were 42 (16%) lost to follow-up. Statistically significant correlations (P<.05) were observed between age, gender, co-morbidity, permanent sick leave, and pre-operative pain with changes in the ODI, COMI, physical and SF-36 mental scales, and lumbar and sciatic VAS. Linear regression analysis showed permanent sick leave and age as predictive factors of disability (β=14.146; 95% CI: 9.09 - 29.58; P<.01 and β=0.334; 95% CI: 0.40 - 0.98, P<.05, respectively), and change in quality of life (β=-8.568; 95% CI: -14.88 - -2.26; p<.01 and β=-0.228, IC 95% CI: -0.40 - -0.06, P<.05, respectively). Based on our findings, age and permanent sick leave have to be considered as negative epidemiologic predictive factors of the outcome of degenerative lumbar disease surgery. Copyright © 2012 SECOT.

    The utilization of orthotic devices for lumbar degenerative disease has been justified from both a prognostic and therapeutic perspective. As a prognostic tool, bracing is applied prior to surgery to determine if immobilization of the spine leads to symptomatic relief and thus justify the performance of a fusion. Since bracing does not eliminate motion, the validity of this assumption is questionable. Only one low-level study has investigated the predictive value of bracing prior to surgery. No correlation between response to bracing and fusion outcome was observed; therefore a trial of preoperative bracing is not recommended. Based on low-level evidence, the use of bracing is not recommended for the prevention of low-back pain in a general working population, since the incidence of low-back pain and impact on productivity were not reduced. However, in laborers with a history of back pain, a positive impact on lost workdays was observed when bracing was applied. Bracing is recommended as an option for treatment of subacute low-back pain, as several higher-level studies have demonstrated an improvement in pain scores and function. The use of bracing following instrumented posterolateral fusion, however, is not recommended, since equivalent outcomes have been demonstrated with or without the application of a brace.

    To assess the clinical potential and limitations of magnetic resonance imaging (MRI) in degenerative lumbar spinal diseases, the findings of MR imaging were compared with those of myelography and CT. The subjects were 80 patients with intervertebral disc herniation (46), spondylosis (28), degenerative spondylolisthesis (5), and spondylolysis (one). There was a good correlation between sagittal MRI (T1-weighted images) and myelography in measuring the anteroposterior diameter and the compression rate of the injured dural canal in all disease categories. However, MRI was inferior, irrespective of sagittal and coronal images, to myelography in detecting blocking of the dural canal and intradural findings such as redundant nerve roots. MRI was inferior to selective nerve root infiltration in visualizing the compression of the nerve root, irrespective of diseases; however, there was no difference in abnormal findings of the running of nerve root between the two modalities. Transverse MRI was superior to CT in visualizing the nerve root. Thus, MRI alone is insufficient for the diagnosis of degenerative lumbar spinal diseases, and the other modalities should be supplementary for pathophysiological understanding of these diseases.

    Objectives Despite lumbar degenerative disc disease (LDDD) being significantly associated with non-specific low back pain and effective treatment remaining elusive, specialist multidisciplinary clinical stakeholder opinion remains unexplored. The present study examines the views of such experts. Design A reliable and valid electronic survey was designed to establish trends using theoretical constructs relating to current assessment and management practices. Clinicians from the Society of Back Pain Research (SBPR) UK were invited to take part. Quantitative data were collated and coded using Bristol Online Surveys (BOS) software, and content analysis was used to systematically code and categorise qualitative data. Setting Specialist multidisciplinary spinal interest group in the UK. Participants 38/141 clinically active, multidisciplinary SBPR members with specialist spinal interest participated. Among them, 84% had >9 years postgraduate clinical experience. Interventions None. Outcome measures Frequency distributions were used to establish general trends in quantitative data. Qualitative responses were coded and categorised in relation to each theme and percentage responses were calculated. Results LDDD symptom recurrence, in the absence of psychosocial influence, was associated with physical signs of joint stiffness (26%), weakness (17%) and joint hypermobility (6%), while physical factors (21%) and the ability to adapt (11%) were postulated as reasons why some experience pain and others do not. No one management strategy was supported exclusively or with consensus. Regarding effective modalities, there was no significant difference between allied health professional and medic responses (p=0.1–0.8). The future of LDDD care was expressed in terms of improvements in patient communication (35%), patient education (38%) and treatment stratification (24%). Conclusions Results suggest that multidisciplinary expert spinal clinicians appear to follow UK

    Dynesys (Dynamic Neutralization System) was designed to overcome the shortcomings of fusion. The Dynesys top loading (DTL) system is a new alternative Dynesys system that can be applied via a minimally invasive procedure. This study aimed to ascertain whether DTL is a suitable device for motion preservation and prevention of instability, and to compare the clinical and radiological outcomes between DTL and Dynesys. In this study, 12 patients were treated with Dynesys and 21 patients were treated with DTL. Back and leg pain were evaluated using the visual analog scale. The Oswestry Disability Index was used to evaluate the patients' function. Range of motion (ROM) at the operative level and for the whole lumbar spine was measured pre- and postoperatively. The length of wound, blood loss, length of hospital stay, and operation duration were also compared. All patients were followed up for 12-76 months. Scores on the visual analog scale and Oswestry Disability Index were significantly improved postoperatively. The median ROM of the whole spine and index level ROM in all patients showed 12.5% and 79.6% loss, respectively. The DTL group exhibited significantly better results in terms of blood loss, wound length, and operation duration, in addition to early ambulation. In conclusion, Dynesys and DTL are semirigid fixation systems that can significantly improve clinical symptoms and signs. Our results suggested that DTL was better than Dynesys as a result of it being a minimally invasive procedure. However, further study with large sample sizes and longer follow-up durations is required to validate the effects of these dynamic stabilizers.

Our objective was to evaluate the safety and effectiveness of lumbar fusion in the treatment of LBP due to DDD. Materials and Methods: Two-hundred and five consecutive patients with single or multi-level DDD underwent lumbar decompression and instrumented fusion for the treatment of chronic LBP between the years of 2008 and 2011. The primary outcome measures in this study were back and leg pain visual analogue scale (VAS, patient reported % resolution of preoperative back pain and leg pain, reoperation rate, perioperative complications, blood loss and hospital length of stay (LOS. Results: The average resolution of preoperative back pain per patient was 84% (n = 205 while the average resolution of preoperative leg pain was 90% (n = 190 while a mean follow-up period of 528 days (1.5 years. Average VAS for combined back and leg pain significantly improved from a preoperative value of 9.0 to a postoperative value of 1.1 (P ≤ 0.0001, a change of 7.9 points for the cohort. The average number of lumbar disc levels fused per patient was 2.3 (range 1-4. Median postoperative LOS in the hospital was 1.2 days. Average blood loss was 108 ml perfused level. Complications occurred in 5% of patients (n = 11 and the rate of reoperation for symptomatic adjacent segment disease was 2% (n = 4. Complications included reoperation at index level for symptomatic pseudoarthrosis with hardware failure (n = 3; surgical site infection (n = 7; repair of cerebrospinal fluid leak (n = 1, and one patient death at home 3 days after discharge. Conclusion: Lumbar fusion for symptomatic DDD can be a safe and effective treatment for medically refractory LBP with or without leg pain.

    Lumbar degenerative kyphosis (LDK) is a subgroup of the flat-back syndrome and is most commonly caused by unique life styles, such as a prolonged crouched posture during agricultural work and performing activities of daily living on the floor. Unfortunately, LDK has been used as a byword for degenerative sagittal imbalance, and this sometimes causes confusion. The aim of this review was to evaluate the exact territory of LDK, and to introduce another appropriate term for degenerative sagittal deformity. Unlike what its name suggests, LDK does not only include sagittal balance disorder of the lumbar spine and kyphosis, but also sagittal balance disorder of the whole spine and little lordosis of the lumbar spine. Moreover, this disease is closely related to the occupation of female farmers and an outdated Asian life style. These reasons necessitate a change in the nomenclature of this disorder to prevent misunderstanding. We suggest the name "primary degenerative sagittal imbalance" (PDSI), which encompasses degenerative sagittal misalignments of unknown origin in the whole spine in older-age patients, and is associated with back muscle wasting. LDK may be regarded as a subgroup of PDSI related to an occupation in agriculture. Conservative treatments such as exercise and physiotherapy are recommended as first-line treatments for patients with PDSI, and surgical treatment is considered only if conservative treatments failed. The measurement of spinopelvic parameters for sagittal balance is important prior to deformity corrective surgery. LDK can be considered a subtype of PDSI that is more likely to occur in female farmers, and hence the use of LDK as a global term for all degenerative sagittal imbalance disorders is better avoided. To avoid confusion, we recommend PDSI as a newer, more accurate diagnostic term instead of LDK.

    Full Text Available Objective To compare the postoperative muscle damage after either posterior lumbar interbody fusion (PLIF or minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF with the aid of X-Tube system in patients with singlelevel degenerative lumbar spinal disease. Methods The clinical data of 52 patients (males 28, females 24, aged 54.3±7.8 years with single-level degenerative lumbar spinal disease undergoing MIS-TLIF assisted by the X-Tube system from Oct 2010 to Sep 2011 was analyzed retrospectively. The operative time, intraoperative blood loss, postoperative drainage volume, postoperative bedtime, and serum creatine kinase (CK level 1 day before surgery and 1, 3 and 5 days after surgery were recorded and compared with those of 38 patients (males 20, females 18, aged 51.6±8.6 years with the same disease undergoing conventional open PLIF during the corresponding period. The back pain visual analogue score (VAS, Oswestry disability index (ODI score and imaging examination were performed before operation, after operation and during follow-up duration for each patient. Results There was no significant difference in the gender, age, clinical diagnosis, lesion location, preoperative CK level, VAS and ODI scores between the two groups (P>0.05. The operative time was longer in MIS-TLIF group than in PLIF group (P0.05. Radiological followup observation revealed good fusion 6 months after operation in all the patients. Conclusion The X-Tube-assisted MIS-TLIF has several advantages over conventional open PLIF, such as less intraoperative blood loss, milder muscle damage, and lighter back pain.

    Paradigm change has recently taken place in spine surgery with the application of minimally invasive techniques. Minimally invasive techniques have several advantages over the open traditional techniques: less blood loss, preservation of spine muscle integrity, shorter hospitalization, early mobilization, reduced pain levels, lower risk of infection. The presented cases cover following lumbar pathologies: segmental spinal instability, LV-SI grade II. spondylolisthesis, degenerative spondylolisthesis, spine trauma. Unilateral or bilateral mini-open technique was employed in the degenerative cases, depending on symptoms and signes. If unilateral symptoms--pathology was identified, screws and rod were implanted percutaneously on the side contralateral to the pathology. The segmental fusion between vertebral bodies was always assured by a cage and autologous bone. The presented trauma case involved combined AO type A2 and B fractures. The anterior column was strengthened with vertebral body stents filled with bone cement, the posterior column was fixed with a percutaneously implanted screw rod system. Insertion of stents in the collapsed vertebra significantly increased the vertebral body height and also improved the stability of the spine. Minimally invasive spine surgery techniques appear more advantageous over the traditional open spine surgery that necessitates for large midline approaches.

    The current costs associated with spine care are unsustainable. The productivity loss and time away from work in gainfully employed patients contributes greatly to the financial burden. Therefore, it is vital to identify the factors associated with returning to work after lumbar spine surgery. We present a predictive model of ability to return to work (RTW) after lumbar spine surgery for degenerative spine disease. Total 4694 patients undergoing elective spine surgery for degenerative lumbar disease who were employed were entered into a prospective multicenter registry (N2QOD). Baseline and 3-month postoperative patient-reported outcomes: Oswestry Disability Index (ODI), EQ-5D, NRS back and leg pain were recorded. The time to RTW was defined as the period between operation time and date of returning to work. A multivariable Cox proportional hazards regression model, including an array of preoperative factors, was fitted for RTW. The model performance was measured by the c-index. Eighty-two percent of patients (n = 3855) returned to work within 3 -months postoperatively. The risk-adjusted predictors of lower likelihood of RTW were preoperatively employed but not working at the time of presentation, those occupied with manual labor, on worker's compensation, on liability insurance, baseline ODI and NRS-BP scores, female sex, African American race, history of diabetes mellitus, and higher ASA grades. The likelihood of RTW within 3 months was higher in patients with higher education level compared with those with less than high school level education. The c-index of our model performance was 0.71. We present a novel predictive model for probability of RTW after lumbar spine surgery. Spine care providers can use this model to educate patients and encourage them in shared decision making regarding the RTW outcome. This will result in better communication between patients and clinicians and improve recovery expectations, which will ultimately increase the likelihood of a

    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.

    There are few objective measures of functional impairment to support clinical decision making in lumbar degenerative disc disease (DDD). We present the validation (and reliability measures) of the Timed Up and Go (TUG) test. In a prospective, 2-center study, 253 consecutive patients were assessed using the TUG test. A representative cohort of 110 volunteers served as control subjects. The TUG test values were assessed for validity and reliability. The TUG test had excellent intra- (intraclass correlation coefficient: 0.97) and interrater reliability (intraclass correlation coefficient: 0.99), with a standard error of measurement of 0.21 and 0.23 seconds, respectively. The validity of the TUG test was demonstrated by a good correlation with the Visual Analog Scale (VAS) back (Pearson's correlation coefficient [PCC]: 0.25) and VAS (PCC: 0.29) leg pain, functional impairment (Roland-Morris Disability Index [PCC: 0.38] and Oswestry Disability Index [PCC: 0.34]), as well as with health-related quality of life (Short Form-12 Mental Component Summary score [PCC: -0.25], Short Form-12 Physical Component Summary score [PCC: -0.32], and EQ-5D [PCC: -0.28]). The upper limit of "normal" was 11.52 seconds. Mild (lower than the 33rd percentile), moderate (33rd to 66th percentiles), and severe objective functional impairment (higher than the 66th percentile) as determined by the TUG test was 18.4 seconds, respectively. The TUG test is a quick, easy-to-use, valid, and reliable tool to evaluate objective functional impairment in patients with lumbar degenerative disc disease. In the clinical setting, patients scoring a TUG test time of over 12 seconds can be considered to have functional impairment.

    OBJECT There is a paradigm shift toward rewarding providers for quality rather than volume. Complications appear to occur at a fairly consistent frequency in large aggregate data sets. Understanding how complications affect long-term patient-reported outcomes (PROs) following degenerative lumbar surgery is vital. The authors hypothesized that 90-day complications would adversely affect long-term PROs. METHODS Nine hundred six consecutive patients undergoing elective surgery for degenerative lumbar disease over a period of 4 years were enrolled into a prospective longitudinal registry. The following PROs were recorded at baseline and 12-month follow-up: Oswestry Disability Index (ODI) score, numeric rating scales for back and leg pain, quality of life (EQ-5D scores), general physical and mental health (SF-12 Physical Component Summary [PCS] and Mental Component Summary [MCS] scores) and responses to the North American Spine Society (NASS) satisfaction questionnaire. Previously published minimum clinically important difference (MCID) threshold were used to define meaningful improvement. Complications were divided into major (surgicalsite infection, hardware failure, new neurological deficit, pulmonary embolism, hematoma and myocardial infarction) and minor (urinary tract infection, pneumonia, and deep venous thrombosis). RESULTS Complications developed within 90 days of surgery in 13% (118) of the patients (major in 12% [108] and minor in 8% [68]). The mean improvement in ODI scores, EQ-5D scores, SF-12 PCS scores, and satisfaction at 3 months after surgery was significantly less in the patients with complications than in those who did not have major complications (ODI: 13.5 ± 21.2 vs 21.7 ± 19, lumbar spine surgery have significant impact on the short-term PROs. Patients with complications, however, do eventually achieve clinically meaningful outcomes and report satisfaction equivalent to those without major complications. This information allows a physician to

    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.

    BACKGROUND:Lumbar paravertebral muscles play an important role for lumbar spinal stability. Increasing studies emphasize on the change of paravertebral muscles in patients with lumbar degenerative disease and therefore have important clinical significance for the rehabilitation training of paravertebral muscle in patients with lumbar degenerative disease. OBJECTIVE:To review the research progress of the change of paravertebral muscle in patients with lumbar degenerative disease and to look into the future development prospects. METHODS:A computer-based online search of PubMed and WANFANG DATA between 1986 and 2014 was performed with the key words“lumbar vertebra, paravertebral muscle, psoas major, multifidus muscle, cross sectional area, muscle atrophy, fatty infiltration, muscle biopsy, MRI, electromyography”in English and Chinese, respectively. The clinical and experimental studies addressing the changes of paravertebral muscle in patients with lumbar degenerative disease were included. According to the inclusion and exclusion criteria, 48 literatures were included into the final analysis, 8 Chinese and 40 English. RESULTS AND CONCLUSION:The change of paravertebral muscle in patients with lumbar degenerative disease includes muscle atrophy and fatty infiltration. The changes of paravertebral muscles are often detected with B-ultrasound, CT, MRI, EMG and muscle biopsy. Due to the differences of sample size, age and study method, there are different results, even conflicting.

    In an effort to diminish pain or progressive instability, due to either the pathological process or as a result of surgical decompression, one of the primary goals of a fusion procedure is to achieve a solid arthrodesis. Assuming that pain and disability result from lost mechanical integrity of the spine, the objective of a fusion across an unstable segment is to eliminate pathological motion and improve clinical outcome. However, conclusive evidence of this correlation, between successful fusion and clinical outcome, remains elusive, and thus the necessity of documenting successful arthrodesis through radiographic analysis remains debatable. Although a definitive cause and effect relationship has not been demonstrated, there is moderate evidence that demonstrates a positive association between radiographic presence of fusion and improved clinical outcome. Due to this growing body of literature, it is recommended that strategies intended to enhance the potential for radiographic fusion are considered when performing a lumbar arthrodesis for degenerative spine disease.

    OBJECTIVE Current costs associated with spine care are unsustainable. Productivity loss and time away from work for patients who were once gainfully employed contributes greatly to the financial burden experienced by individuals and, more broadly, society. Therefore, it is vital to identify the factors associated with return to work (RTW) after lumbar spine surgery. In this analysis, the authors used data from a national prospective outcomes registry to create a predictive model of patients' ability to RTW after undergoing lumbar spine surgery for degenerative spine disease. METHODS Data from 4694 patients who underwent elective spine surgery for degenerative lumbar disease, who had been employed preoperatively, and who had completed a 3-month follow-up evaluation, were entered into a prospective, multicenter registry. Patient-reported outcomes-Oswestry Disability Index (ODI), numeric rating scale (NRS) for back pain (BP) and leg pain (LP), and EQ-5D scores-were recorded at baseline and at 3 months postoperatively. The time to RTW was defined as the period between operation and date of returning to work. A multivariable Cox proportional hazards regression model, including an array of preoperative factors, was fitted for RTW. The model performance was measured using the concordance index (c-index). RESULTS Eighty-two percent of patients (n = 3855) returned to work within 3 months postoperatively. The risk-adjusted predictors of a lower likelihood of RTW were being preoperatively employed but not working at the time of presentation, manual labor as an occupation, worker's compensation, liability insurance for disability, higher preoperative ODI score, higher preoperative NRS-BP score, and demographic factors such as female sex, African American race, history of diabetes, and higher American Society of Anesthesiologists score. The likelihood of a RTW within 3 months was higher in patients with higher education level than in those with less than high school

This work aims to elucidate sex differences in subjective and objective measures of pain, functional impairment, and health-related quality of life (HRQoL) in patients with lumbar degenerative disc disease. In a prospective 2-center study, back and leg pain (visual analogue scale [VAS]), functional disability (Oswestry Disability Index and Roland-Morris Disability Index), and HRQoL (EuroQol-5D and Short Form [SF12]) were collected for consecutive patients undergoing lumbar spine surgery. Objective functional impairment (OFI) was estimated using age-adjusted and sex-adjusted cutoff values for the timed-up-and-go (TUG) test. A healthy cohort of n = 110 subjects served as the control group. Univariate and multivariate analyses were performed to test the association between sex and pain, subjective and OFIs, and HRQoL. The study comprised n = 305 patients (41.6% females). Female patients had more VAS back pain (P = 0.002) and leg pain (P = 0.014). They were more likely to report higher functional impairment in terms of Oswestry Disability Index (P = 0.005). Similarly, HRQoL measured with the EuroQol-5D index (P = 0.012) and SF12 physical composite score (P = 0.005) was lower in female patients. Female patients reported higher VAS back and leg pain, functional impairment, and reduced HRQoL than male patients. However, there were no sex differences with respect to the presence and degree of OFI measured by the TUG test using age-adjusted and sex-adjusted cutoff values. As such, the TUG may be a good test to overcome sex bias for the clinical assessment of patients with degenerative disc disease.

    Prospective controlled clinical study on low back pain (LBP). To investigate the possible effects of radiographic and other related parameters on LBP in patients underwent decompression and posterolateral instrumented fusion for degenerative lumbar spine disease. Sagittal balance of the spine after spine surgery has gained increasing interest regarding its correlation with LBP and fusion rate. To our knowledge, no advanced statistical analysis on the effects of sagittal roentgenographic and other parameters on LBP after lumbar surgery has been published. Forty-five patients with an average age of 63 years, who underwent pedicle-screw fixation in 2, 3, and 4 vertebrae for degenerative lumbar spine disease were selected to be included in this study. Radiographic and self-assessment (bodily pain, short form-36) data were evaluated using advanced statistics (multifactorial analysis) to investigate all possible correlations between a dependent parameter (LBP) and independent parameters (sex, extension of instrumentation, sagittal spinal balance, and angular motion at the adjacent free level above instrumentation). All patients were observed for an average of 5.5 years (range, 5-7 years). Male patients showed significantly more improvement of LBP than female counterparts (P = 0.024). LBP improved after surgery by the first year (P spine disease.This research suggests that the methods directed at the improvement in sagittal spinal balance of the lumbar spine, careful selection of fusion levels, and improvement of fusion rate might be beneficial for decreasing LBP after surgery in degenerative lumbar spine disease.

    Objective To investigate the safety and clinical effects of surgical treatment of degenerative lumbar spine diseases in elderly patients. Methods 42 patients with degenerative lumbar spine diseases who were enrolled from January 2008 to December 2011 selectively underwent surgical treatment, including 6 patients with lumbar disc herniation, 10 patients with lumbar disc herniation and spinal stenosis, 6 patients with degenerative lumbar spondylolisthesis and 20 patients with spinal stenosis. There were 28 males and 14 females, with an average age of 77.2 years old ( range;75-84 years ). They were followed up for a mean period of 31 months ( range;17-64 months ). The preoperative concomitant diseases, postoperative complications and relevant treatment methods were analyzed. The clinical effects were evaluated by the Oswestry Disability Index ( ODI ) and the Visual Analogue Scale ( VAS ). Based on the anteroposterior ( AP ), lateral and dynamic X-ray iflms of the lumbar spine during the follow-up, the lumbar spinal stability, lumbar spinal fusion and implants were observed after the surgery. Results The postoperative complications included 7 cases of increased blood pressure, 1 case of angina, 1 case of cerebral infarction, 4 cases of pulmonary infection and 3 cases of cerebrospinal lfuid leakage. Operational segment instability or internal ifxation failure was not found based on the X-ray films 1 year after the surgery or in the latest follow-up. The ODI was improved from ( 71.1±19.2 )%preoperatively to ( 22.0±11.3 )%postoperatively ( P<0.01 ). The VAS of low back pain was improved from ( 6.0±2.1 ) preoperatively to ( 2.2±1.7 ) postoperatively ( P<0.01 ). The VAS of lower leg pain was improved from ( 7.9±1.7 ) to ( 3.1±2.1 ) ( P<0.01 ). 39 of 42 patients got satisifed results, and the other 3 patients were basically content with the results. Conclusions With the concomitant diseases and postoperative complications actively controlled, elderly patients with

    Obesity (BMI>30Kg/m(2)) is a pandemic with severe medical and financial implications. There is growing evidence that relates certain metabolic processes within the adipose tissue, preferentially abdominal fat, with a low-intensity chronic inflammatory state mediated by adipokines and other substances that favor disk disease and chronic low back pain. Obesity greatly conditions both the preoperative evaluation and the spinal surgical technique itself. Some meta-analyses have confirmed an increase of complications following lumbar spine surgery (mainly infections and venous thrombosis) in obese subjects. However, functional outcomes after lumbar spine surgery are favorable although inferior to the non-obese population, acknowledging that obese patients present with worse baseline function levels and the prognosis of conservatively treated obese cohorts is much worse. The impact of preoperative weight loss in spine surgery has not been prospectively studied in these patients. Copyright © 2017 Sociedad Española de Neurocirugía. Publicado por Elsevier España, S.L.U.

    Full Text Available Introduction. Various clinical conditions can cause low back pain, and in most cases it is of a degenerative origin. Degenerative disc disease is a common condition which affects young to middle-aged men and women equally. Changes in the mechanical properties of the disc lead to degenerative arthritis in the intervertebral joints, osteophytes, and narrowing the intervertebral foramen or the spinal canal. Pathophysiology. Degenerative cascade, described by Kirkaldy-Willis, is the widely accepted pathophysiologic model describing the degenerative process as it affects the lumbar spine in 3 phases. Diagnosis. There are two forms of low back pain secondary to degenerative disc disease: a lumbalgia and b lumbar radiculopathy. Limitation of movement, problems with balance, pain, loss of reflexes in the extremities, muscle weakness, loss of sensation or other signs of neurological damage can be found on physical examination. For accurate diagnosis, it is often necessary to combine clinical examination and sophisticated technology. Treatment. Coservative treatment consists of rest, physical therapy, pharmacological therapy and injection therapy. Physical rehabilitation with active patient participation is a key approach to treatment of patients with discogenic pain. Physical therapy, occupational therapy and kinesitherapy are important for improving muscle strength, endurance, and flexibility. Disc surgery is performed if surgical intervention is required. .

    Full Text Available Study Design. Prospective clinical study. Objective. This study compares the clinical results of anterior lumbar total disc replacement and posterior transpedicular dynamic stabilization in the treatment of degenerative disc disease. Summary and Background Data. Over the last two decades, both techniques have emerged as alternative treatment options to fusion surgery. Methods. This study was conducted between 2004 and 2010 with a total of 50 patients (25 in each group. The mean age of the patients in total disc prosthesis group was 37,32 years. The mean age of the patients in posterior dynamic transpedicular stabilization was 43,08. Clinical (VAS and Oswestry and radiological evaluations (lumbar lordosis and segmental lordosis angles of the patients were carried out prior to the operation and 3, 12, and 24 months after the operation. We compared the average duration of surgery, blood loss during the surgery and the length of hospital stay of both groups. Results. Both techniques offered significant improvements in clinical parameters. There was no significant change in radiologic evaluations after the surgery for both techniques. Conclusion. Both dynamic systems provided spine stability. However, the posterior dynamic system had a slight advantage over anterior disc prosthesis because of its convenient application and fewer possible complications.

    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. In a recent study comparing 29 MI-TLIF patients and 29 open TLIF, MI-TLIF was associated with longer operative time, less blood loss, shorter hospital stay, with no difference in SF-36 scores at six months and two years. Whether it can replace traditional TLIF as the surgery of

    Numerous studies assessed the effects of smoking on lumbar degenerative disk disease (DDD); they focused on patient-reported outcome measures (PROMs) and yielded conflicting results. In this 2-center study on consecutive patients receiving surgical treatment for lumbar DDD, subjective functional impairment (SFI) in terms of PROMs including visual analog scale back and leg pain, Roland-Morris, Oswestry Disability Index, Euro-Qol-5D, and a Short-Form 12 physical component summary was determined at baseline, 3 days, 6 weeks, 6 months, and 1 year postoperatively. Age- and sex-adjusted T-scores of objective functional impairment (OFI) were determined using the Timed Up and Go test up to 6 weeks postoperatively. The responder status was defined by the minimal clinically important difference. We analyzed 375 patients (n = 96 [25.6%] smokers and n = 279 [74.4%] nonsmokers). SFI on any of the PROMs before treatment was similar in smokers and nonsmokers. Smokers were more likely to have OFI in univariate logistic regression analysis (95% confidence interval 1.31-3.37, P = 0.002). In multivariate analysis, however, this relationship became insignificant (95% confidence interval 0.85-2.38, P = 0.184). The smoking status had no predictive capacity on the 6-week SFI or OFI responder status, and there were no differences in any of the PROMs until the 1-year follow-up. PROMs measuring SFI for pain intensity, functional impairment, and health-related quality of life were similar in smokers and nonsmokers before surgery for lumbar DDD, as well as postoperatively. The smoking status has negligible impact on the Timed Up and Go test, which appears to be a robust assessment tool for OFI. Copyright © 2016 Elsevier Inc. All rights reserved.

    The Timed Up and Go (TUG) test, as a measure of objective functional impairment in lumbar degenerative disk disease (DDD), complements patient-reported outcome measures (PROMs) of subjective functional impairment. Prospective 2-center study on consecutive patients scheduled for surgical treatment for lumbar DDD who underwent an objective (TUG test) and subjective (PROMs) functional assessment before and 1 and 3 days after surgery. PROMs included the visual analog scale (VAS), Roland-Morris Disability Index (RMDI), Oswestry Disability Index (ODI), Euro-Qol (EQ-5D), and Short Form 12 (SF-12) questionnaires. On completion of each assessment, patients were asked whether they would prefer performing the TUG test or completing the PROMs questionnaires. A total of 109 of 125 patients (87.2%) completed the assessments. Preoperatively, patients were 2.18 times as likely to prefer the TUG test to the PROMs (odds ratio [OR], 2.18; 95% confidence interval [CI], 1.27-3.75). On postoperative days 1 and 3, patients were 5.79 (OR, 5.79; 95% CI, 3.23-10.37) and 6.33 times as likely to prefer the TUG test to the PROMs, respectively (OR, 6.33; 95% CI, 3.51-11.41). There were no statistical differences in baseline characteristics, TUG t scores, VAS, RMDI, ODI, SF-12, and EQ-5D index between patients preferring either the TUG test or the PROMs questionnaires. The TUG test is preferred over a battery of PROMs by 60%-70% of patients with lumbar DDD not only in the preoperative, but also in the postoperative, setting. High functional disability does not result in avoidance of the TUG test, and repeated assessments lead to higher preference. Copyright © 2016 Elsevier Inc. All rights reserved.

    This study was designed to determine the association between LSE, spondylolisthesis, facet arthropathy, lumbar canal stenosis, BMI, radiculopathy and bone marrow edema at conventional lumbar spine MR imaging. This is a retrospective radiological study; 441 consecutive patients with low back pain (224 men and 217 women; mean age 57.3 years; mean BMI 26) underwent conventional lumbar MRI using a 1.5-T magnet (Avanto, Siemens). Lumbar MR images were reviewed by consensus for the presence of LSE, spondylolisthesis, facet arthropathy, lumbar canal stenosis, radiculopathy and bone marrow edema. Descriptive statistics and association studies were conducted using STATA software 11.0. Association studies have been performed using linear univariate regression analysis and multivariate regression analysis, considering LSE as response variable. The overall prevalence of LSE was 40%; spondylolisthesis (p = 0.01), facet arthropathy (p back pain. Longitudinal simultaneous X-ray/MRI studies should be conducted to test the relationship of LSE with lumbar spinal instability and low back pain.

    In order to evaluate the predictive effect of non-invasive preoperative imaging methods on surgical outcomes of lumbar fusion for patients with degenerative disc disease (DDD) and refractory chronic axial low back pain (LBP), the authors conducted a retrospective review of 45 patients with DDD and refractory LBP submitted to anterior lumbar interbody fusion (ALIF) at a single center from 2007 to 2010. Surgical outcomes - as measured by Visual Analog Scale (VAS/back pain) and Oswestry Disability Index (ODI) - were evaluated pre-operatively and at 6 weeks, 3 months, 6 months, and 1 year post-operatively. Linear mixed-effects models were generated in order to identify possible preoperative imaging characteristics (including bone scan/99mTc scintigraphy increased endplate uptake, Modic endplate changes, and disc degeneration graded according to Pfirrmann classification) which may be predictive of long-term surgical outcomes . After controlling for confounders, a combined score, the Lumbar Fusion Outcome Score (LUFOS), was developed. The LUFOS grading system was able to stratify patients in two general groups (Non-surgical: LUFOS 0 and 1; Surgical: LUFOS 2 and 3) that presented significantly different surgical outcomes in terms of estimated marginal means of VAS/back pain (p = 0.001) and ODI (p = 0.006) beginning at 3 months and continuing up to 1 year of follow-up. In conclusion,  LUFOS has been devised as a new practical and surgically oriented grading system based on simple key parameters from non-invasive preoperative imaging exams (magnetic resonance imaging/MRI and bone scan/99mTc scintigraphy) which has been shown to be highly predictive of surgical outcomes of patients undergoing lumbar fusion for treatment for refractory chronic axial LBP.

    Full Text Available Osteoarthritis, a degenerative joint disease, is the most commonrheumatic disorder mainly in a geriatric population. Manifestationsare pain, stiffness and functional loss in the affected joint.According to etiology it is classifi ed as primary (or idiopathicand secondary. Some risk factors for disease development aregenetics, race, age, sex, obesity, occupational activities andarticular biomechanics. Pathogenesis is the same for any cause orlocalization, being catabolic alterations, with synthesis, inhibitionand reparing intent of the cartilage matrix. Metalloproteinases andcytokines (IL-1,IL-6,TNF-α actions promote infl ammatory reactionand cartilage degradation. Pain, the most important symptom,does not correlate with radiologic fi ndings. Peripheral osteoarthritisoccurs predominantly in the knee, hip and hand. Diagnosis is basedon clinical features, laboratorial tests and radiological changes.Rheumatological associations’ guidelines for treatment includenon-pharmacologic (education, physiotherapy, assistive devices,and pharmacologic (analgesics, anti-infl ammatory drugs therapyand surgery. Arthroplasty seems to work better than medicines, butshould be used if other treatments have failed.

    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.

    Degenerative cysts of the lumbar spine encompass a heterogeneous group of cystic lesions that are presumed to share a common aetiology. Some of these cysts may be incidental findings, whereas others may produce acute or chronic symptoms. These cysts have been categorized using various combinations of topographic and pathological characteristics and by their attachment to or communication with a specific spinal structure.

    The Timed Up and Go (TUG) test is a reliable tool for evaluating objective functional impairment (OFI) in patients with degenerative disc disease before a surgical intervention. The aim of this study is to assess the validity of the TUG test to measure change in function postoperatively. In a prospective two-center study, OFI was assessed by the TUG test in patients scheduled for lumbar spine surgery, as well as 3 days (D3) and 6 weeks (W6) postoperatively. At each time point, the TUG test results were correlated with established subjective measures of pain intensity (visual analogue scale (VAS) for back and leg pain), functional impairment (Oswestry Disability Index (ODI)) and health-related quality of life (HRQoL; Short Form-12 (SF12)). The patient cohort comprised 136 patients with a mean age of 57.7 years; 76 were males, 54 had a microdiscectomy for lumbar disc herniation, 58 a decompression for a lumbar spinal stenosis, 24 had a surgical fusion procedure. The mean OFI t-score was 125.1 before surgery, and as patients improved on the subjective measures in the postoperative interval, the OFI t-score likewise decreased to 118.8 (D3) and 103.4 (W6). The Pearson correlation coefficient (PCC) between the OFI t-score and VAS leg pain was 0.187 preoperatively (p = 0.029) and 0.252 at W6 (p = 0.003). The PCC between OFI t-score and the ODI was 0.324 preoperatively (p < 0.001) and 0.413 at W6 (p < 0.001). The PCC between OFI t-score and physical HRQoL (SF12) was -0.091 preoperatively (p = 0.293) and -0.330 at W6 (p < 0.001). The TUG test is sensitive to change, and reflects the postoperative functional outcome even more exact than preoperatively, as indicated by better correlation coefficients of the OFI t-score with subjective measures of pain intensity, functional impairment and HRQoL.

  10. Lumbar Degenerative Kyphosis’ Is Not Byword for Degenerative Sagittal Imbalance: Time to Replace a Misconception

    Lumbar degenerative kyphosis (LDK) is a subgroup of the flat-back syndrome and is most commonly caused by unique life styles, such as a prolonged crouched posture during agricultural work and performing activities of daily living on the floor. Unfortunately, LDK has been used as a byword for degenerative sagittal imbalance, and this sometimes causes confusion. The aim of this review was to evaluate the exact territory of LDK, and to introduce another appropriate term for degenerative sagittal deformity. Unlike what its name suggests, LDK does not only include sagittal balance disorder of the lumbar spine and kyphosis, but also sagittal balance disorder of the whole spine and little lordosis of the lumbar spine. Moreover, this disease is closely related to the occupation of female farmers and an outdated Asian life style. These reasons necessitate a change in the nomenclature of this disorder to prevent misunderstanding. We suggest the name “primary degenerative sagittal imbalance” (PDSI), which encompasses degenerative sagittal misalignments of unknown origin in the whole spine in older-age patients, and is associated with back muscle wasting. LDK may be regarded as a subgroup of PDSI related to an occupation in agriculture. Conservative treatments such as exercise and physiotherapy are recommended as first-line treatments for patients with PDSI, and surgical treatment is considered only if conservative treatments failed. The measurement of spinopelvic parameters for sagittal balance is important prior to deformity corrective surgery. LDK can be considered a subtype of PDSI that is more likely to occur in female farmers, and hence the use of LDK as a global term for all degenerative sagittal imbalance disorders is better avoided. To avoid confusion, we recommend PDSI as a newer, more accurate diagnostic term instead of LDK. PMID:28264231

    Study Design Retrospective study. Objectives To assess the fatty atrophy of the lumbar paraspinal muscles (LPMs) as determined using magnetic resonance imaging in patients with lumbar degenerative disk disease (DDD) and focal disk herniation and to determine if fatty atrophy is associated with patient-reported outcome measures (PROMS). Methods One hundred sixty-five patients with lumbar DDD were identified from a PROMS database of >1,500 patients. These patients were divided into two study groups: DDD alone (n = 58) and DDD with disk herniation (n = 107). A grid was randomly applied to the axial scans at the L3–L4, L4–L5, and L5–S1 levels. The muscle-to-fat ratio of the LPMs was recorded and compared with PROMS data. Subcutaneous fat thickness at each level was also measured. Results This study found no difference in the muscle-to-fat ratio between the DDD and disk herniation groups. There was no association between the muscle-to-fat ratio and PROMS data in either group. There was significantly more subcutaneous fat at all levels in the DDD group as compared with the disk prolapse group. In DDD and disk prolapses, subcutaneous fat was thicker in women (p = 0.013 and 0.001). In patients with DDD, more subcutaneous fat was associated with disability (p Muscle content of erector spinae and multifidus negatively correlated with increasing age in both groups at the L3–L4 level. Conclusions Muscle fat content in the LPM does not appear to relate to PROMS. Muscle content decreases with age. Those with low back pain (DDD) have greater subcutaneous fat thickness. PMID:27190744

    Patients presenting with stenosis associated with a spondylolisthesis will often describe signs and symptoms consistent with neurogenic claudication, radiculopathy, and/or low-back pain. The primary objective of surgery, when deemed appropriate, is to decompress the neural elements. As a result of the decompression, the inherent instability associated with the spondylolisthesis may progress and lead to further misalignment that results in pain or recurrence of neurological complaints. Under these circumstances, lumbar fusion is considered appropriate to stabilize the spine and prevent delayed deterioration. Since publication of the original guidelines there have been a significant number of studies published that continue to support the utility of lumbar fusion for patients presenting with stenosis and spondylolisthesis. Several recently published trials, including the Spine Patient Outcomes Research Trial, are among the largest prospective randomized investigations of this issue. Despite limitations of study design or execution, these trials have consistently demonstrated superior outcomes when patients undergo surgery, with the majority undergoing some type of lumbar fusion procedure. There is insufficient evidence, however, to recommend a standard approach to achieve a solid arthrodesis. When formulating the most appropriate surgical strategy, it is recommended that an individualized approach be adopted, one that takes into consideration the patient's unique anatomical constraints and desires, as well as surgeon's experience.

    OBJECTIVE The purpose of this study was to provide a systematic and comprehensive review of the existing literature regarding postfusion rehabilitation. METHODS Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, the authors conducted an exhaustive review of multiple electronic databases. Potential articles were screened using inclusion/exclusion criteria. Two authors independently analyzed these studies using predefined data fields, including study quality indicators such as level of evidence and availability of accepted patient-reported outcomes measures. These findings were synthesized in a narrative format. A third author resolved disagreements regarding the inclusion of a study. RESULTS Twenty-one articles with I or II levels of evidence were included in the review. The authors divided the findings of the literature review into several groups: rehabilitation terminology, timing and duration of postfusion rehabilitation, the need for rehabilitation relative to surgery-related morbidity, rehabilitation's relationship to outcomes, and cognitive and psychosocial aspects of postsurgical rehabilitation. Current evidence generally supports formal rehabilitation after lumbar fusion surgery. Starting physical therapy at the 12-week postoperative mark results in better outcomes at lower cost than an earlier, 6-week start. Where available, psychosocial support improves outcomes. However, a number of the questions could not be answered with high-grade evidence. In these cases, the authors used "best evidence available" to make recommendations. There are many cases in which different types of caregivers use clinical terminology differently. The data supporting an optimal protocol for postfusion rehabilitation remains elusive but, using the data available, the authors have crafted recommendations and a model protocol, which is currently undergoing prospective study. CONCLUSIONS Rehabilitation has long been a common feature in

    Study Design Retrospective database analysis. Objective To assess the effect glycemic control has on perioperative morbidity and mortality in patients undergoing elective degenerative lumbar spine surgery. Summary of background data Diabetes Mellitus (DM) is a prevalent disease of glucose dysregulation that has been demonstrated to increase morbidity and mortality following spine surgery. However, there is limited understanding of whether glycemic control influences surgical outcomes in DM patients undergoing lumbar spine procedures for degenerative conditions. Methods The Nationwide Inpatient Sample was analyzed from 2002 to 2011. Hospitalizations were isolated based on International Classification of Diseases Ninth Revision, Clinical Modification procedural codes for lumbar spine surgery and diagnoses codes for degenerative conditions of the lumbar spine. Patients were then classified into three cohorts: controlled diabetics, uncontrolled diabetics and non-diabetics. Patient demographic data, acute complications and hospitalization outcomes were determined for each cohort. Results A total of 403,629 (15.7%) controlled diabetics and 19,421(0.75%) uncontrolled diabetics underwent degenerative lumbar spine surgery from 2002-2011. Relative to non-diabetics, uncontrolled diabetics had significantly increased odds of cardiac complications, deep venous thrombosis and post-operative shock; additionally, uncontrolled diabetics also had an increased mean length of stay (approximately 2.5 days), greater costs (1.3-fold) and a greater risk of inpatient mortality (odds ratio=2.6, 95% confidence interval=1.5-4.8, p degenerative lumbar spine surgery leads to increased risk of acute complications and poor outcomes. Patients with uncontrolled DM, or poor glucose control, may benefit from improving glycemic control prior to surgery. PMID:24983935

Intracanal approaches frequently require partial or total facetectomy, which may lead to instability. Solely extraforaminal approaches may offer limited visualization of the more medial superiorly exiting and inferiorly exiting nerve roots; this approach is also more complicated at L5-S1 due to the often large L5 transverse process and the iliac wing. Methods: Nine patients with intraforaminal L5-S1 disc herniations, foraminal stenosis, or synovial cysts underwent contralateral interlaminar approaches for lesion resection. Preoperative and postoperative visual analog scale scores were evaluated, and complications were reviewed. Results: All 9 patients demonstrated immediate postoperative clinical improvement. None of the patients exhibited complications and none developed instability or neuropathic disorders. Conclusions: Although the number of cases in our sample was very small (9 in total), the contralateral interlaminar approach appeared to effectively address multiple degenerative L5-S1 foraminal pathologies. Large studies are needed to further evaluate the pros and cons of this approach. PMID:27713854

    Degenerative disease of the spine is a definition that includes a wide spectrum of degenerative abnormalities. Degeneration involves bony structures and the intervertebral disk, although many aspects of spine degeneration are strictly linked because the main common pathogenic factor is identified in chronic overload. During life the spine undergoes continuous changes as a response to physiologic axial load. These age-related changes are similar to pathologic degenerative changes and are a common asymptomatic finding in adults and elderly persons. A mild degree of degenerative changes is paraphysiologic and should be considered pathologic only if abnormalities determine symptoms. Imaging allows complete evaluation of static and dynamic factors related to degenerative disease of the spine and is useful in diagnosing the different aspects of spine degeneration.

    In an attempt to enhance the potential to achieve a solid arthrodesis and avoid the morbidity of harvesting autologous iliac crest bone (AICB) for a lumbar fusion, numerous alternatives have been investigated. The use of these fusion adjuncts has become routine despite a lack of convincing evidence demonstrating a benefit to justify added costs or potential harm. Potential alternatives to AICB include locally harvested autograft, calcium-phosphate salts, demineralized bone matrix (DBM), and the family of bone morphogenetic proteins (BMPs). In particular, no option has created greater controversy than the BMPs. A significant increase in the number of publications, particularly with respect to the BMPs, has taken place since the release of the original guidelines. Both DBM and the calciumphosphate salts have demonstrated efficacy as a graft extender or as a substitute for AICB when combined with local autograft. The use of recombinant human BMP-2 (rhBMP-2) as a substitute for AICB, when performing an interbody lumbar fusion, is considered an option since similar outcomes have been observed; however, the potential for heterotopic bone formation is a concern. The use of rhBMP-2, when combined with calcium phosphates, as a substitute for AICB, or as an extender, when used with local autograft or AICB, is also considered an option as similar fusion rates and clinical outcomes have been observed. Surgeons electing to use BMPs should be aware of a growing body of literature demonstrating unique complications associated with the use of BMPs.

    Study Design Retrospective study. Purpose To analyze outcomes of posterior lumbar interbody fusion (PLIF) stand-alone cages. Overview of Literature PLIF for degenerative disk disease using stand-alone cages has lost its popularity owing to implant-related complications and pseudoarthrosis. Methods We analyzed the records of 45 patients (18 women, 27 men), operated between January 1994 and December 1996, with a mean follow-up of 18 years 3 months (20 years 3 months–22 years 3 months). Clinical outcomes were measured using visual analogue score (VAS), Oswestry disability index (ODI), Odom's criteria, and radiological measurements of fusion rate, Cobb angle, and implant-related complications conducted at the preoperative evaluation, hospital discharge, 12-month follow-up, and final follow-up. Results Preoperative mean VAS (back) was 6.9 and VAS (radicular) was 7.2, with mean improvements (p Pseudoarthrosis was observed in five patients (11.1%), of whom, three (6.6%) required re-operation. Preoperative disk height was 9.23 mm, which increased to 13.33 mm in the immediate postoperative evaluation and was maintained at 10.0 mm at the final follow-up (p <0.05). The preoperative mean L1–S1 Cobb angle was 34.7°, which changed to 44.7° in the immediate postoperative evaluation and dropped to 39.7° at the final follow-up (p <0.005). Conclusions PLIF stand-alone cages were associated with good clinical outcomes. Although the fusion rate was excellent, maintenance of disk heights and a lordotic alignment were not achieved in the long term. PMID:27994787

    The Timed Up and Go Test (TUG Test) has previously been described as a reliable tool to evaluate objective functional impairment in patients with degenerative disc disease. The aim of this study was to assess the minimum clinically important difference (MCID) of the TUG Test. The TUG Test (measured in seconds) was correlated with validated patient-reported outcome measures (PROs) of pain intensity (Visual Analog Scale for back and leg pain), functional impairment (Oswestry Disability Index, Roland Morris Disability Index), and health-related quality of life measures (Short Form-12 and EuroQol 5D). Three established methods were used to establish anchor-based MCID values using responders of the following PROs (Visual Analog Scale back and leg pain, Oswestry Disability Index, Roland Morris Disability Index, EuroQol 5D index, and Short Form-12 Physical Component Summary) as anchors: (1) average change, (2) minimum detectable change, and (3) change difference approach. One hundred patients with a mean ± SD age of 56.2 ± 16.1 years, 57 (57%) male, 45 patients undergoing microdiscectomy, 35 undergoing lumbar decompression, and 20 undergoing fusion surgery were studied. The 3 MCID computation methods revealed a range of MCID values according to the PRO used from 0.9 s (Oswestry Disability Index based on the change difference approach) to 6.0 s (EuroQol 5D index based on the minimum detectable change approach), with a mean MCID of 3.4 s for all measured PROs. The MCID for the TUG Test time is highly variable depending on the computation technique used. The average TUG Test MCID was 3.4 s using all 3 methods and all anchors.

    Objective: To compare fast T1-weighted fluid-attenuated inversion recovery (FLAIR) and T1-weighted turbo spin-echo (TSE) imaging of the degenerative disc disease of the lumbar spine. Materials and methods: Thirty-five consecutive patients (19 females, 16 males; mean age 41 years, range 31-67 years) with suspected degenerative disc disease of the lumbar spine were prospectively evaluated. Sagittal images of the lumbar spine were obtained using T1-weighted TSE and fast T1-weighted FLAIR sequences. Two radiologists compared these sequences both qualitatively and quantitatively. Results: On qualitative evaluation, CSF nulling, contrast at the disc-CSF interface, the disc-spinal cord (cauda equina) interface, and the spinal cord (cauda equina)-CSF interface of fast T1-weighted FLAIR images were significantly higher than those for T1-weighted TSE images (P < 0.001). On quantitative evaluation of the first 15 patients, signal-to-noise ratios of cerebrospinal fluid of fast T1-weighted FLAIR imaging were significantly lower than those for T1-weighted TSE images (P < 0.05). Contrast-to-noise ratios of spinal cord/CSF and normal bone marrow/disc for fast T1-weighted FLAIR images were significantly higher than those for T1-weighted TSE images (P < 0.05). Conclusion: Results in our study have shown that fast T1-weighted FLAIR imaging may be a valuable imaging modality in the armamentarium of lumbar spinal T1-weighted MR imaging, because the former technique has definite superior advantages such as CSF nulling, conspicuousness of the normal anatomic structures and changes in the lumbar spinal discogenic disease and image contrast and also almost equally acquisition times.

    Full Text Available : BACKGROUND: Low back pain (LBP is a common presenting complaint affecting mostly middle aged and older person and traditionally considered as ageing process, but now-a-days large number of younger people are also affected by this debilitating chronic disorder. The cause of early onset of degenerative spine disease is multifactorial, but genetical predisposition plays very important role. AIMS AND OBJECTIVE: To find out association between genetic predisposition and degenerative spine disease in adult patients and to assess the pattern of MRI findings of various degenerative diseases in lumbo-sacral spine. MATERIAL AND METHOD: The present cross-sectional study had been performed among 100 selected patients in 1yr period, who presented with chief complaint of chronic low back pain. After taking detailed clinical and professional history, MRI of lumbosacral spine had been performed. Total 100 patients were divided in two groups on the basis of genetical predisposition. Prevalence and spectrum of degenerative changes were compared between both groups. RESULTS: Hundred patients of 20 to 35-year age had been selected with mean age of 27yr. Out of 100 patients; 47 were male and 53 were female. The most common degenerative findings were desiccation of disc (95% followed by disc bulge, herniation, spinal canal stenosis, ligamentum flavum hypertrophy, facet joint hypertrophy and modic changes. L4-L5 and L5- S1 were the most commonly involved spinal levels for any degenerative pathology. CONCLUSION: Good association is seen between early onset of degenerative spine disease and genetical predisposition in patients who have history of similar type degenerative spine disease in one or more first degree relatives in comparison to those patients who do not have any genetical predisposition. So it can be concluded that heredity play important role in early onset of degenerative spine disease in adults.

    OBJECTIVE The Dynesys, a pedicle-based dynamic stabilization (PDS) system, was introduced to overcome the drawbacks of fusion procedures. Nevertheless, the theoretical advantages of PDS over fusion have not been clearly confirmed. The aim of this study was to compare clinical and radiological outcomes of patients who underwent PDS using the Dynesys system with those who underwent posterior lumbar interbody fusion (PLIF). METHODS The authors searched PubMed, Embase, Web of Science, and the Cochrane Database. Studies that reported outcomes of patients who underwent PDS or PLIF for the treatment of degenerative lumbar spinal disease were included. The primary efficacy end points were perioperative outcomes. The secondary efficacy end points were changes in the Oswestry Disability Index (ODI) and back and leg pain visual analog scale (VAS) scores and in range of motion (ROM) at the treated and adjacent segments. A meta-analysis was performed to calculate weighted mean differences (WMDs), 95% confidence intervals, Q statistics, and I(2) values. Forest plots were constructed for each analysis group. RESULTS Of the 274 retrieved articles, 7 (which involved 506 participants [Dynesys, 250; PLIF, 256]) met the inclusion criteria. The Dynesys group showed a competitive advantage in mean surgery duration (20.73 minutes, 95% CI 8.76-32.70 minutes), blood loss (81.87 ml, 95% CI 45.11-118.63 ml), and length of hospital stay (1.32 days, 95% CI 0.23-2.41 days). Both the Dynesys and PLIF groups experienced improved ODI and VAS scores after 2 years of follow-up. Regarding the ODI and VAS scores, no statistically significant difference was noted according to surgical procedure (ODI: WMD 0.12, 95% CI -3.48 to 3.72; back pain VAS score: WMD -0.15; 95% CI -0.56 to 0.26; leg pain VAS score: WMD -0.07; 95% CI -0.47 to 0.32). The mean ROM at the adjacent segment increased in both groups, and there was no substantial difference between them (WMD 1.13; 95% CI -0.33 to 2.59). Although the

    OBJECT Unintended durotomy is a common occurrence during lumbar spinal surgery, particularly in surgery for degenerative spinal conditions, with the reported incidence rate ranging from 0.3% to 35%. The authors performed a systematic literature review on unintended lumbar spine durotomy, specifically aiming to identify the incidence of durotomy during spinal surgery for lumbar degenerative conditions. In addition, the authors analyzed the incidence of durotomy when minimally invasive surgical approaches were used as compared with that following a traditional midline open approach. METHODS A MEDLINE search using the term "lumbar durotomy" (under the 2015 medical subject heading [MeSH] "cerebrospinal fluid leak") was conducted on May 13, 2015, for English-language medical literature published in the period from January 1, 2005, to May 13, 2015. The resulting papers were categorized into 3 groups: 1) those that evaluated unintended durotomy rates during open-approach lumbar spinal surgery, 2) those that evaluated unintended durotomy rates during minimally invasive spine surgery (MISS), and 3) those that evaluated durotomy rates in comparable cohorts undergoing MISS versus open-approach lumbar procedures for similar lumbar pathology. RESULTS The MEDLINE search yielded 116 results. A review of titles produced 22 potentially relevant studies that described open surgical procedures. After a thorough review of individual papers, 19 studies (comprising 15,965 patients) pertaining to durotomy rates during open-approach lumbar surgery were included for analysis. Using the Oxford Centre for Evidence-Based Medicine (CEBM) ranking criteria, there were 7 Level 3 prospective studies and 12 Level 4 retrospective studies. In addition, the authors also included 6 studies (with a total of 1334 patients) that detailed rates of durotomy during minimally invasive surgery for lumbar degenerative disease. In the MISS analysis, there were 2 prospective and 4 retrospective studies. Finally

    双能X线骨密度仪检测骨密度是诊断骨质疏松症的“金标准”,学者推荐50岁以上人群采用腰椎前后位进行测量.然而骨质疏松症发病率较高的老年人群,常常合并罹患多种脊柱退行性疾病,例如腰椎间盘突出、退行性侧凸、骨赘增生等,这些病理改变可导致腰椎前后位骨密度值准确性降低.因此,提高腰椎骨密度测量准确性,对于骨质疏松症的诊断和治疗具有重要意义.本文就常见的脊柱退行性疾病对腰椎前后位骨密度的影响作一综述,以期帮助临床医生全面评估和诊断骨质疏松症.%Objective Bone mineral density (BMD) detected by dual-energy X-ray absorptiometry can be regarded as the "gold standard" for the diagnosis of osteoporosis. The scholars recommend that all adults over SO years old should conduct the anteroposterior position measurement. However, the elderly population with high incidence of osteoporosis often combines with many degenerative spinal diseases, such as intervertebral disc herniation, degenerative scoliosis, osteophyte formation, etc. These pathological changes in the lumbar spine might reduce the accuracy of BMD in anteroposterior position. So the increase of BMD accuracy is of great significance in diagnosis and treatment of osteoporosis. This article reviews the impacts of spinal degenerative diseases on lumbar bone mineral density and aims to facilitate clinicians to assess and diagnose osteoporosis comprehensively.

    Study Design Level 4 retrospective review. Purpose To compare the radiographic and clinical outcomes between posterior lumbar interbody fusion (PLIF) and lateral lumbar interbody fusion (LLIF) with posterior segmental spinal instrumentation (SSI) for degenerative lumbar spondylolisthesis. Overview of Literature Both PLIF and LLIF have been performed for degenerative spondylolisthesis with good results, but no study has directly compared these two techniques so far. Methods The electronic medical and radiographic records of 78 matched patients were analyzed. In one group, 39 patients underwent PLIF with SSI at 41 levels (L3-4/L4-5), while in the other group, 39 patients underwent the LLIF procedure at 48 levels (L3-4/L4-5). Radiological outcomes such as restoration of disc height and neuroforaminal height, segmental lumbar lordosis, total lumbar lordosis, incidence of endplate fracture, and subsidence were measured. Perioperative parameters were also recorded in each group. Clinical outcome in both groups was assessed by the short form-12, Oswestry disability index and visual analogue scale scores. The average follow-up period was 16.1 months in the LLIF group and 21 months in the PLIF group. Results The restoration of disc height, foraminal height, and segmental lumbar lordosis was significantly better in the LLIF group (p<0.001). The duration of the operation was similar in both groups, but the average blood loss was significantly lower in the LLIF group (p<0.001). However, clinical outcome scores were similar in both groups. Conclusions Safe, effective interbody fusion can be achieved at multiple levels with neuromonitoring by the lateral approach. LLIF is a viable treatment option in patients with new onset symptoms due to degenerative spondylolisthesis who have had previous lumbar spine surgery, and it results in improved sagittal alignment and indirect foraminal decompression.

    Degenerative spinal disorders, including intervertebral disc disease and spondylosis, seldom occur in domestic cats. In contrast, a retrospective study of 13 lions (Panthera leo), 16 tigers (Panthera tigris), 4 leopards (Panthera pardis), 1 snow leopard (Panthera uncia), and 3 jaguars (Panthera onca) from the Knoxville Zoo that died or were euthanatized from 1976 to 1996 indicated that degenerative spinal disease is an important problem in large nondomestic felids. The medical record, radiographic data, and the necropsy report of each animal were examined for evidence of intervertebral disc disease or spondylosis. Eight (three lions, four tigers, and one leopard) animals were diagnosed with degenerative spinal disease. Clinical signs included progressively decreased activity, moderate to severe rear limb muscle atrophy, chronic intermittent rear limb paresis, and ataxia. The age at onset of clinical signs was 10-19 yr (median = 18 yr). Radiographic evaluation of the spinal column was useful in assessing the severity of spinal lesions, and results were correlated with necropsy findings. Lesions were frequently multifocal, included intervertebral disc mineralization or herniation with collapsed intervertebral disc spaces, and were most common in the lumbar area but also involved cervical and thoracic vertebrae. Marked spondylosis was present in the cats with intervertebral disc disease, presumably subsequent to vertebral instability. Six of the animals' spinal cords were examined histologically, and five had acute or chronic damage to the spinal cord secondary to disc protrusion. Spinal disease should be suspected in geriatric large felids with decreased appetite or activity. Radiographic evaluation of the spinal column is the most useful method to assess the type and severity of spinal lesions.

    Full Text Available Background: Degenerative lumbar scoliosis surgery can lead to development of adjacent segment degeneration (ASD after lumbar or thoracolumbar fusion. Its incidence, risk factors, morbidity and correlation between radiological and clinical symptoms of ASD have no consensus. We evaluated the correlation between the occurrence of radiologic adjacent segment disease and certain imperative parameters. Materials and Methods: 98 patients who had undergone surgical correction and lumbar/thoracolumbar fusion with pedicle screw instrumentation for degenerative lumbar scoliosis with a minimum 5 year followup were included in the study. We evaluated the correlation between the occurrence of radiologic adjacent segment disease and imperative patient parameters like age at operation, sex, body mass index (BMI, medical comorbidities and bone mineral density (BMD. The radiological parameters taken into consideration were Cobb′s angle, angle type, lumbar lordosis, pelvic incidence, intercristal line, preoperative existence of an ASD on plain radiograph and magnetic resonance imaging (MRI and surgical parameters were number of the fusion level, decompression level, floating OP (interlumbar fusion excluding L5-S1 level and posterolateral lumbar interbody fusion (PLIF. Clinical outcomes were assessed with the Visual Analogue Score (VAS and Oswestry Disability Index (ODI. Results: ASD was present in 44 (44.9% patients at an average period of 48.0 months (range 6-98 months. Factors related to occurrence of ASD were preoperative existence of disc degeneration (as revealed by MRI and age at operation ( P = 0.0001, 0.0364. There were no statistically significant differences between radiological adjacent segment degeneration and clinical results (VAS, P = 0.446; ODI, P = 0.531. Conclusions: Patients over the age of 65 years and with preoperative disc degeneration (as revealed by plain radiograph and MRI were at a higher risk of developing ASD.

    There is a debate regarding the distal fusion level for degenerative lumbar scoliosis. Whether a healthy L5-S1 motion segment should be included or not in the fusion remains controversial. The purpose of this study was to determine the optimal indication for the fusion to the sacrum, and to compare the results of distal fusion to L5 versus the sacrum in the long instrumented fusion for degenerative lumbar scoliosis. A total of 45 patients who had undergone long instrumentation and fusion for degenerative lumbar scoliosis were evaluated with a minimum 2 year follow-up. Twenty-four patients (mean age 63.6) underwent fusion to L5 and 21 patients (mean age 65.6) underwent fusion to the sacrum. Supplemental interbody fusion was performed in 12 patients in the L5 group and eleven patients in the sacrum group. The number of levels fused was 6.08 segments (range 4-8) in the L5 group and 6.09 (range 4-9) in the sacrum group. Intraoperative blood loss (2,754 ml versus 2,938 ml) and operative time (220 min versus 229 min) were similar in both groups. The Cobb angle changed from 24.7 degrees before surgery to 6.8 degrees after surgery in the L5 group, and from 22.8 degrees to 7.7 degrees in the sacrum group without statistical difference. Correction of lumbar lordosis was statistically better in the sacrum group (P = 0.03). Less correction of lumbar lordosis in the L5 group seemed to be associated with subsequent advanced L5-S1 disc degeneration. The change of coronal and sagittal imbalance was not different in both groups. Subsequent advanced L5-S1 disc degeneration occurred in 58% of the patients in the L5 group. Symptomatic adjacent segment disease at L5-S1 developed in five patients. Interestingly, the development of adjacent segment disease was not related to the preoperative grade of disc degeneration, which proved minimal degeneration in the five patients. In the L5 group, there were nine patients of complications at L5-S1 segment, including adjacent segment disease at

    This prospective longitudinal randomized clinical and radiological study compared the evolution of instrumented posterolateral lumbar and lumbosacral fusion using either coralline hydroxyapatite (CH), or iliac bone graft (IBG) or both in three comparable groups, A, B and C, which included 19, 18 and 20 patients, respectively, who suffered from symptomatic degenerative lumbar spinal stenosis and underwent decompression and fusion. The patients were divided randomly according to the graft used and the side that it was applied. The spines of group A received autologous IBG bilaterally; group B, IBG on the left side and hydroxyapatite mixed with local bone and bone marrow on the right side; group C, hydroxyapatite mixed with local bone and bone marrow bilaterally. The age of the patients in the groups A, B and C was 61+/-11 years, 64+/-8 years and 58+/-8 years, respectively. The SF-36, Oswestry Disability Index (ODI), and Roland-Morris (R-M) surveys were used for subjective evaluation of the result of the surgery and the Visual Analogue Scale (VAS) for pain severity. Plain roentgenograms including anteroposterior, lateral and oblique views, and lateral plus frontal bending views of the instrumented spine and CT scan were used to evaluate the evolution of the posterolateral fusion in all groups and sides. Two independent senior orthopaedic radiologists were asked to evaluate first the evolution of the dorsolateral bony fusion 3-48 months postoperatively with the Christiansen's radiologic method, and secondly the hydroxyapatite resorption course in the spines of groups B and C. The diagnosis of solid spinal fusion was definitively confirmed with the addition of the bending views, CT scans and self-assessment scores. The intraobserver and interobserver agreement (r) for radiological fusion was 0.71 and 0.69, respectively, and 0.83 and 0.76 for evaluation of CH resorption. T(12)-S(1) lordosis and segmental angulation did not change postoperatively. There was no

    The athletic activity of the adult U.S. population has increased markedly in the last 20 years. To evaluate the possible long-term effects of such activity on the cervical and lumbar spine, we studied a group of asymptomatic currently very active lifelong male athletes over age 40 (41-69 years old, av. age 53). Nineteen active, lifelong male athletes were studied with MRI and the results compared with previous imaging studies of other populations. An athletic history and a spine history were also taken. Evidence of asymptomatic degenerative spine disease was similar to that seen in published series of other populations. Degenerative changes including disk protrusion and herniation, spondylosis, and spinal stenosis were present and increased in incidence with increasing patient age. In this group, all MRI findings proved to be asymptomatic and did not limit athletic activity. The incidence of lumbar degenerative changes in our study population of older male athletes was similar to those seen in other populations. 14 refs., 8 figs., 1 tab.

    A dysexecutive syndrome is observed not only in frontotemporal lobar degeneration, but also in subcortical degenerative diseases, and even in Alzheimer's disease whose lesions predominate in temporoparietal associative areas. The association between a dysexecutive syndrome and various cerebral localisations may be explained by the fact that cognitive and behavioral organisation recruits anatomofunctional frontostriatal and frontoparietal circuits. Both animal experimentation and human clinical observation argue in favour of a functional continuity and complementarity among these loops. The prefrontal cortex would be particularly needed in new situations, to inhibit old programs of action not adapted to the present context and to elaborate new ones; the basal ganglia would be rather required by the repetition of the situation to progressively transform the new program in routine. If we refer to Shallice model, we can hypothesize that optimal executive functions require the preservation not only of the Supervisory Attentional System, mainly dependent on the prefrontal cortex, but also of the Contention Scheduling, recruiting the basal ganglia, and of the Schemas of Action, represented in parietal and premotor areas. Therefore, the neuropsychological assessment of patients with degenerative diseases contributes to the understanding of the anatomofunctional architecture of executive functions.

    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 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.

    2012-01-01

    Full Text Available Quantitative fluoroscopy (QF is an emerging technology for measuring intervertebral motion patterns to investigate problem back pain and degenerative disc disease. This International Forum was a networking event of three research groups (UK, US, Hong Kong, over three days in San Francisco in August 2009. Its aim was to reach a consensus on how best to record, analyse, and communicate QF information for research and clinical purposes. The Forum recommended that images should be acquired during regular trunk motion that is controlled for velocity and range, in order to minimise externally imposed variability as well as to correlate intervertebral motion with trunk motion. This should be done in both the recumbent passive and weight bearing active patient configurations. The main recommended outputs from QF were the true ranges of intervertebral rotation and translation, neutral zone laxity and the consistency of shape of the motion patterns. The main clinical research priority should initially be to investigate the possibility of mechanical subgroups of patients with chronic, nonspecific low back pain by comparing their intervertebral motion patterns with those of matched healthy controls.

    1995-06-01

    In order to estimate the ralationship between the position of dorsal root ganglia (DRG) and radicular symptoms, anatomical study was done on 81 cadavers, and a clinical study with MRI was done on 20 cases of lumbar disc herniation and 20 of lumbar spondylosis with L{sub 5} radiculopathy. The position of DRG is not related to the occurrence of radicular symptoms in disc herniation, while in lumbar spondylosis proximally placed DRG are related to both of unilateral and bilateral occurrence of redicular symptoms. Unilateral occurrence of radicular symptoms is influenced by surrounding tissues of the nerve root, rather than the position of DRG. (author).

    Abstract The purpose of our study is to evaluate sagittal parameters in 2-level lumbar degenerative spondylolisthesis (DS) (TLDS). A total of 15 patients with TLDS, 40 patients with single-level DS (SLDS), and 30 normal volunteers as control were included in our study. All subjects performed on full spine X-ray. Two categorized data were analyzed: patient characteristics—age, sex, body mass index, radiographic parameters-pelvic incidence (PI), pelvic tilt (PT), lumbar lordosis (LL), sacral slope (SS), PI–LL, Cobb between the fifth thoracic vertebral and 12th thoracic vertebral (T5–T12), sagittal vertical axis (SVA) Cobb angle of spondylolisthesis level (CSL), ratio of PT to SS (PT/SS), CSL/LL, variation trend of SS over PI, and LL over PI. The PI (73.1° vs 52.9°), SS (50.8° vs 32.2°), LL (53.1° vs 46.9°), SVA (66.1 vs 22.0 mm), PI–LL (20.0° vs 6.0°), and CSL (23.6° vs 20.0°) in TLDS were significantly larger than these in SLDS. The PI (73.1° vs 40.6°), PT (22.3° vs 17.1°), SS (50.8° vs 23.5°), LL (53.1° vs 32.5°), PI–LL (20.0° vs 8.1°), and SVA (66.1 vs 17.0 mm) in TLDS were significantly larger than those in the normal group (NG). The PI (52.9° vs 40.6°), PT (21.0° vs 17.1°), SS (32.2° vs 23.5°), LL (46.9° vs 32.5°), and SVA (22.0 vs 17.0 mm) in SLDS were significantly higher than those in NG. However, PT/SS (44.0%), LL over PI (y = 0.39x + 24.25), SS over PI (y = 10.79 + 0.55x) were lower in TLDS than these in SLDS (63.8%, y = 0.41x + 25, y = 0.65x − 2.09, respectively), and the similar tend between SLDS and NG (74.0%, y = 0.49x + 13.09, y = 0.67x − 3.9, respectively). Our results showed that 2-level lumbar DS, which was caused by multiple-factors, has a severe sagittal imbalance, but single-level has not any. When we plan for surgical selection for 2-level lumbar DS, global sagittal balance must be considered. PMID:27977581

    To evaluate the results of a novel rigid-dynamic stabilization technique in lumbar degenerative segment diseases (DSD), expressly pointing out the preservation of postoperative lumbar lordosis (LL). Forty-one patients with one level lumbar DSD and initial disc degeneration at the adjacent level were treated. Circumferential lumbar arthrodesis and posterior hybrid instrumentation were performed to preserve an initial disc degeneration above the segment that has to be fused. Clinical and spino-pelvic parameters were evaluated pre- and postoperatively. At 2-year follow-up, a significant improvement of clinical outcomes was reported. No statistically significant difference was noted between postoperative and 2-year follow-up in LL and in disc/vertebral body height ratio at the upper adjacent fusion level. When properly selected, this technique leads to good results. A proper LL should be achieved after any hybrid stabilization to preserve the segment above the fusion.

    Objective To summarize and analyze the efficacy of coflex interspinous fixation system in the treatment of lumbar degenerative diseases and the causes of postoperative disc re-herniation. Methods The clinical data of 40 patients with degenerative lumbar diseases who were treated with coflex interspinous fixation system from December 2008 to January 2011 were retrospectively summarized and analyzed. There were 16 males and 24 females, whose mean age was 58.3 years old (range; 39-77 years). Simple posterior decompression+coflex fixation were used in 15 patients and decompression+discectomy+coflex fixation in 25 patients. The oswestry disability index (ODI) and visual analogue scale (VAS) of lumbocrural pain were used to evaluate the clinical efficacy. The anteroposterior, lateral, hyperextension and hyperflexion X-ray films of the lumbar spine were taken in the preoperative and postoperative follow-up. The range of motion (ROM) of the lumbar of the operational segments and changes in disc height index were observed. The patients without significant symptom relief were examined with lumbar spine MRI. Results All patients were followed up. The mean follow-up time was 11.2 months (range; 6-24 months). The ODI index scores dropped from 43.88±16.34 preoperatively to 14.63±6.84 in the latest follow-up. The VAS scores dropped from 5.94±1.39 preoperatively to 1.13±0.96 in the latest follow-up. The differences were statistically significant (PO.05). The intervertebral space ROM was 8.32±3.56 preoperatively and 3.64±2.72 postoperatively The differences were statistically significant (P0.05). The disc height index had a significant increase postoperatively (P0.05). The index of the disc height was gradually decreased at the end of the follow-up. The differences were not statistically significant comparing with the preoperative data (P>0.05). Within 6 months postoperatively, original symptoms aggravated in 3 cases receiving single segment decompression and intervertebral

    Full Text Available Objective. To assess risk factors оf pedicle screw instability after decompression and fusion in patients with degenerative lumbar spine disease.Materials and methods. This is a prospective non-randomized study, the results of 130 surgical interventions with pedicle instrumentation in patients with degenerative lumbar spine diseases were studied. Minimal follow up period accounts for 18 months. Before intervention computed tomography (CT was applied and cancellous bone radiodensity was measured.Patients were treated with nerve root decompression and pedicle screw fixation stand-alone or with lumbar interbody fusion. During follow-up period computed tomography was applied and cases with evidence of pedicle screw loosening were detected. Radiodensity of cancellous bone, extension of fixation, extensiveness of decompression, application of interbody fusion, incomplete vertebra body reduction and heterogeneity of studied group were taken into account as potential risk factors of implant instability development. The correlation between pedicle screws loosening rate and mentioned predictors was estimated using logistic regression analysis.Results. Radiodensity of vertebra body cancellous bone getting decreased, the increase number of fixed levels and extensiveness of facet joints and ligaments resection are associated with the increased risk of a screw loosening development. Laminectomy, interbody fusion, altered biomechanics associated with incomplete vertebra body reduction and L5–S1 segment included into fixed zone did not have a significant influence on pedicle screws loosening rate. Bias related to heterogeneity of studied group was also insignificant. Goodness-of-fit of estimated general logistic regression model: № 2 = 67,57851; p < 0,0001. This model classified correctly 81,5% cases with sensitivity and specificity of 77,4% and 85,3% respectively.Conclusion. Radiodensity of a vertebra cancellous bone, number of fixed levels and

    Degenerative disc disease (DDD) is a common cause of lower back pain with radicular symptoms and has a significant socioeconomic impact given the associated disability. Limited effective conservative therapeutic options result in many turning to surgical alternatives for management, which vary in the rate of success and also carry an increased risk of morbidity and mortality associated with the procedures. Several animal based studies and a few human pilot studies have demonstrated safety and suggest efficacy in the treatment of DDD with mesenchymal stem cells (MSCs). The use of bone marrow-derived MSCs for the treatment of DDD is promising and in the present study we report on the safety and efficacy findings from a registry based proof of concept study using a percutaneous intradiscal injection of cultured MSCs for the management of DDD with associated radicular symptoms. Thirty-three patients with lower back pain and disc degeneration with a posterior disc bulge diagnosed on magnetic resonance imaging (MRI) met the inclusion criteria and were treated with culture-expanded, autologous, bone marrow-derived MSCs. Prospective registry data was obtained at multiple time intervals up to 6 years post-treatment. Collected outcomes included numeric pain score (NPS), a modified single assessment numeric evaluation (SANE) rating, functional rating index (FRI), measurement of the intervertebral disc posterior dimension, and adverse events. Three patients reported pain related to procedure that resolved. There were no serious adverse events (i.e. death, infection, or tumor) associated with the procedure. NPS change scores relative to baseline were significant at 3, 36, 48, 60, and 72 months post-treatment. The average modified SANE ratings showed a mean improvement of 60% at 3 years post-treatment. FRI post-treatment change score averages exceeded the minimal clinically important difference at all time points except 12 months. Twenty of the patients treated underwent

    Objective To investigate and analyze the clinical curative effect of transmultifidus lumbar interbody fusion in the treatment of lumbar degenerative diseases. Methods 62 patients with lumbar degenerative diseases who came to our hos-pital from April,2011 to July,2012 were randomly divided into the control group and the experimental group according to the random number method. There were 31 cases in each group. The control group accepted transforaminal lumbar interbody fusion while the experimental group accepted transmultifidus lumbar interbody fusion. The clinical curative effect of the two groups was compared. Results Blood loss and postoperative drainage volume of the experimental group was significantly less than that of the control group(P0. 05). The VAS score in the 3rd day and 2 weeks after the operation,the ODI index in 1st month and 6th month of the experimental group was statistically better than that of the control group(P0. 05).

    Abstract Objective: The aim of the study was to evaluate the efficacy and safety of transforaminal lumbar interbody fusion (TLIF) versus posterolateral fusion (PLF) in degenerative lumbar spondylosis. Methods: A systematic literature review was performed to obtain randomized controlled trials (RCTs) and observational studies (OSs) of TLIF and PLF for degenerative lumbar spondylosis. Trials performed before November 2015 were retrieved from the Medline, EMBASE, Cochrane library, and Chinese databases. Data extraction and quality evaluation of the trials were performed independently by 2 investigators. A meta-analysis was performed using STATA version 12.0. Results: Two RCTs and 5 OSs of 630 patients were included. Of these subjects, 325 were in the TLIF and 305 were in the PLF group. Results showed that TLIF did not increase the fusion rate based on RCTs (relative risk [RR] = 1.06; 95% confidence interval [CI]: 0.95–1.18; P = 0.321), but increased it based on OSs (RR = 1.14; 95% CI: 1.07–1.23; P = 0.000) and overall (RR = 1.11; 95% CI: 1.05–1.18; P = 0.001) as compared with PLF. TLIF was able to improve the clinical outcomes based on 1 RCT (RR = 1.33; 95% CI: 1.11–1.59, P = 0.002) and overall (RR = 1.19; 95% CI: 1.07–1.33; P = 0.001), but not based on OSs (RR = 1.11; 95% CI: 0.97–1.27; P = 0.129) as compared with PLF. There were no differences between TLIF and PLF in terms of visual analogue scale, Oswestry Disability Index, reoperation, complications, duration of surgical procedure, blood loss, and hospitalization. Conclusions: In conclusion, evidence is not sufficient to support that TLIF provides higher fusion rate than PLF, and this poor evidence indicates that TLIF might improve only clinical outcomes. Higher quality, multicenter RCTs are needed to better define the role of TLIF and PLF. PMID:27749558

    OBJECT Usually additional anchors into the ilium are necessary in long fusion to the sacrum for degenerative lumbar spine disorders (DLSDs), especially for adult spine deformity. Although the use of anchors is becoming quite common, surgeons must always keep in mind that the sacroiliac (SI) joint is mobile and they should be aware of the kinematic properties of the SI joint in patients with DLSDs, including adult spinal deformity. No previous study has clarified in vivo kinematic changes in the SI joint with respect to patient age, sex, or parturition status or the presence of DLSDs. The authors conducted a study to clarify the mobility and kinematic characteristics of the SI joint in patients with DLSDs in comparison with healthy volunteers by using in vivo 3D motion analysis with voxel-based registration, a highly accurate, noninvasive method. METHODS Thirteen healthy volunteers (the control group) and 20 patients with DLSDs (the DLSD group) underwent low-dose 3D CT of the lumbar spine and pelvis in 3 positions (neutral, maximal trunk flexion, and maximal trunk extension). SI joint motion was calculated by computer processing of the CT images (voxel-based registration). 3D motion of the SI joint was expressed as both 6 df by Euler angles and translations on the coordinate system and a helical axis of rotation. The correlation between joint motion and the cross-sectional area of the trunk muscles was also investigated. RESULTS SI joint motion during trunk flexion-extension was minute in healthy volunteers. The mean rotation angles during trunk flexion were 0.07° around the x axis, -0.02° around the y axis, and 0.16° around the z axis. The mean rotation angles during trunk extension were 0.38° around the x axis, -0.08° around the y axis, and 0.08° around the z axis. During trunk flexion-extension, the largest amount of motion occurred around the x axis. In patients with DLSDs, the mean rotation angles during trunk flexion were 0.57° around the x axis, 0.01

    Full Text Available This prospective study aimed to compare the efficacy of epidural (EDA versus intravenous (PCA application of analgesics after lumbar fusion. Fifty-two patients scheduled for elective posterior instrumented lumbar fusion were randomized into two groups. EDA patients received an epidural catheter intraoperatively, and administration of ropivacain and sulfentanil was started after a normal post-operative wake-up test in the recovery room area. PCA patients received intravenous opioids in the post-operative period. Differences between EDA and PCA groups in terms of patient satisfaction with respect to pain relief were not significant. Nevertheless, EDA patients reported less pain on the third day after surgery. There were significantly more side effects in the EDA group, including complete reversible loss of sensory function and motor weakness. There were no major side effects, such as infection or persisting neurological deficits, in either group. The routine use of epidural anesthesia for lumbar spine surgery has too many risks and offers very little advantage over PCA.

  6. Radiographical analysis concernig the etiology of degenerative spondylolisthesis of the lumbar spine

    The purpose of this article is to evaluate radiographically degenerative spondylolisthesis of the lumbar spine, with the main focus on the configuration of posterior elements. A comparative study between 49 cases of degenerative spondylolisthesis and 99 cases of other lumbar disorders was performed, using 13 radiographical parameters. The results clearly indicate the posterior elements of degenerative spondylolisthesis shifted horizontally and sagittally to allow slipping. This was due to the weak bony hook mechanism. Furthermore, almost all facet joints were morphologically classified as sagittal or intermediate type. Another meaningful difference was the alignment of the lumbar spine which showed an increase in both lordosis and lumbosacral angle. On the other hand, the level of Jacoby's line was almost the same in both groups. These characteristic configurations could be the cause of listhesis, although further study should be carried out to elucidate whether they are present at the non-listhetic stage. (author).

    This study investigates the effect of a new Chinese massage technique named "press-extension" on degenerative lumbar with disc herniation and facet joint dislocation, and provides a biomechanical explanation of this massage technique. Self-developed biomechanical software was used to establish a normal L1-S1 lumbar 3D FE model, which integrated the spine CT and MRI data-based anatomical structure. Then graphic technique is utilized to build a degenerative lumbar FE model with disc herniation and facet joint dislocation. According to the actual press-extension experiments, mechanic parameters are collected to set boundary condition for FE analysis. The result demonstrated that press-extension techniques bring the annuli fibrosi obvious induction effect, making the central nucleus pulposus forward close, increasing the pressure in front part. Study concludes that finite element modelling for lumbar spine is suitable for the analysis of press-extension technique impact on lumbar intervertebral disc biomechanics, to provide the basis for the disease mechanism of intervertebral disc herniation using press-extension technique.

    Cerebellar syndromes result in distinct clinical symptoms, such as ataxia, dysarthria, dysmetria, intention tremor and eye movement disorders. In addition to the medical history and clinical examination, imaging is particularly important to differentiate other diseases, such as hydrocephalus and multi-infarct dementia from degenerative cerebellar diseases. Degenerative diseases with cerebellar involvement include Parkinson's disease, multiple system atrophy as well as other diseases including spinocerebellar ataxia. In addition to magnetic resonance imaging (MRI), nuclear medicine imaging investigations are also helpful for the differentiation. Axial fluid-attenuated inversion recovery (FLAIR) and T2-weighted sequences can sometimes show a signal increase in the pons as a sign of degeneration of pontine neurons and transverse fibers in the basilar part of the pons. The imaging is particularly necessary to exclude other diseases, such as normal pressure hydrocephalus (NPH), multi-infarct dementia and cerebellar lesions. (orig.) [German] Klinisch imponieren Kleinhirnsyndrome durch Ataxie, Dysarthrie, Dysmetrie, Intentionstremor und Augenbewegungsstoerungen.

Zu den degenerativen Erkrankungen mit Kleinhirnbeteiligung gehoeren der Morbus Parkinson, die Multisystematrophie sowie weitere Erkrankungen einschliesslich der spinozerebellaeren Ataxien. Neben der MRT sind auch nuklearmedizinische Untersuchungen zur Differenzierung hilfreich.

    A comprehensive economic analysis generally involves the calculation of indirect and direct health costs from a societal perspective as opposed to simply reporting costs from a hospital or payer perspective. Hospital charges for a surgical procedure must be converted to cost data when performing a cost-effectiveness analysis. Once cost data has been calculated, quality-adjusted life year data from a surgical treatment are calculated by using a preference-based health-related quality-of-life instrument such as the EQ-5D. A recent cost-utility analysis from a single study has demonstrated the long-term (over an 8-year time period) benefits of circumferential fusions over stand-alone posterolateral fusions. In addition, economic analysis from a single study has found that lumbar fusion for selected patients with low-back pain can be recommended from an economic perspective. Recent economic analysis, from a single study, finds that femoral ring allograft might be more cost-effective compared with a specific titanium cage when performing an anterior lumbar interbody fusion plus posterolateral fusion.

    Proper patient selection is of utmost importance in the surgical treatment of degenerative disc disease (DDD) with chronic low back pain (CLBP). Among other factors, gender was previously found to influence lumbar fusion surgery outcome. This study investigates whether gender affects clinical outcome after lumbar fusion. This is a national registry cohort study. Between 2001 and 2011, 2,251 men and 2,521 women were followed prospectively within the Swedish National Spine Register (SWESPINE) after lumbar fusion surgery for DDD and CLBP. Patient-reported outcome measures (PROMs), visual analog scale (VAS) for leg and back pain, Oswestry Disability Index (ODI), quality of life (QoL) parameter EQ5D, and labor status and pain medication were collected preoperatively, 1 and 2 years after surgery. Gender differences of baseline data and PROM improvement from baseline were analyzed. The effect of gender on clinically important improvement of PROM was determined in a multivariate logistic regression model. Furthermore, gender-related differences in return-to-work were investigated. Preoperatively, women had worse leg pain (pback pain (p=.002), lower QoL (ppain, function, and QoL (all ppain (odds ratio [OR]=1.39, 95% confidence interval [CI]: 1.19-1.61, pback pain (OR=1.20,95% CI:1.03-1.40, p=.02) as well as ODI (OR=1.24, 95% CI:1.05-1.47, p=.01), but improved at a slower pace in leg pain (pback pain (p=.009), and disability (p=.008). No gender differences were found in QoL and return to work at 2 years postoperatively. Swedish women do not have worse results than men after spinal fusion surgery. Female patients present with worse pain and function preoperatively, but improve more than men do after surgery. Copyright © 2016 The Author(s). Published by Elsevier Inc. All rights reserved.

    Objectives: To investigate the morphology of endplate shape in lumbar degenerative disc disease by means of magnetic resonance imaging (MRI) and the correlation between endplate shape and lumbar disc degeneration. Methods: A retrospective review was carried out in this study. The preoperative lumbar MRIs of 110 patients with single lumbar intervertebral disc herniation (group A) and 35 patients suffering from disco-genic low back pain(group B) were reviewed and analyzed respectively. The morphology of endplate was classified into three groups: concave, flat and irregular based on the midsagittal Tl -weighed MRI; the degree of disc degeneration was graded on T2 -weighed MRI according to the Pfirrmann's method, with one to five points behaving grade 1 to V; all endplates were determined by Modic grading system. The associations between morphology of endplate in lower lumbar spine and disc degenerative degree as well as Modic changes were evaluated retrospectively. Results: (DAmong the 435 lower lumbar spine endplates, concave represented the maximum proportion(215/435), with 50.6% in group A(167/330) and 45.7% in group B(48/105), and they almost sited in L3/4(108/215) and 14/5(83/215). Flat accounted for 29.0%(126/435). mostly sited in L5/S1 (76/126). Irregular represented the least proportion(94/435), with 23.0% in group A(76/330) and 17.1% in group B(18/105), almost sited in L5/Sl(45/94). ?In group A, the average degenerative degree for concave, flat and irregular endplate was 3.31±0.81 point, 3.66±0.64 point and 4.16±0.67 point respectively, which showed significant difference (P0.05). ?In group B, the average degeneration degree for concave, flat and irregular endplale was 3.23±0.86 point, 3.54±0.85 point and 3.94±0.54 point respectively, with significant difference existing only in concave and irregular shape(P<0.05). Conclusions: Endplate morphology is associated with degree of disc degeneration and Modic changes. Disc degeneration presents from concave

    The most diffused surgical techniques for stabilization of the painful degenerated and instable lumbar spine, represented by transpedicular screws and rods instrumentation with or without interbody cages or disk replacements, require widely open and/or difficult and poorly anatomical accesses. However, such surgical techniques and approaches, although still considered "standard of care", are burdened by high costs, long recovery times and several potential complications. Hence the effort to open new minimally-invasive surgical approaches to eliminate painful abnormal motion. The surgical and radiological communities are exploring, since more than a decade, alternative, minimally-invasive or even percutaneous techniques to fuse and lock an instable lumbar segment. Another promising line of research is represented by the so-called dynamic stabilization (non-fusion or motion preservation back surgery), which aims to provide stabilization to the lumbar spinal units (SUs), while maintaining their mobility and function. Risk of potential complications of traditional fusion methods (infection, CSF leaks, harvest site pain, instrumentation failure) are reduced, particularly transitional disease (i.e., the biomechanical stresses imposed on the adjacent segments, resulting in delayed degenerative changes in adjacent facet joints and discs). Dynamic stabilization modifies the distribution of loads within the SU, moving them away from sensitive (painful) areas of the SU. Basic biomechanics of the SU will be discussed, to clarify the mode of action of the different posterior stabilization devices. Most devices are minimally invasive or percutaneous, thus accessible to radiologists' interventional practice. Devices will be described, together with indications for patient selection, surgical approaches and possible complications.

    Zeliger Harold I.

    2015-03-01

    Full Text Available The onset of human degenerative diseases in humans, including type 2 diabetes, cardiovascular disease, neurological disorders, neurodevelopmental disease and neurodegenerative disease has been shown to be related to exposures to persistent organic pollutants, including polychlorinated biphenyls, chlorinated pesticides, polybrominated diphenyl ethers and others, as well as to polynuclear aromatic hydrocarbons, phthalates, bisphenol-A and other aromatic lipophilic species. The onset of these diseases has also been related to exposures to transition metal ions. A physiochemical mechanism for the onset of degenerative environmental disease dependent upon exposure to a combination of lipophilic aromatic hydrocarbons and transition metal ions is proposed here. The findings reported here also, for the first time, explain why aromatic hydrocarbons exhibit greater toxicity than aliphatic hydrocarbons of equal carbon numbers.

    [Objective]To investigate the clinical efficacy of applying the Quadrant minimally invasive treatment system for the treatment of lumbar degenerative disease. [Method] From February 2011 to April 2012,34 patients treated with lumbar fusion under Quadrant minimally invasive treatment system were analysed. The postoperative indexes, the intervertebral height recovery and complications were recorded. The clinical efficacy was evaluated according to the Japanese Orthopaedic Association (JOA) scores and visual analogue scale(VSA) scores. [Result]The average operation time was 174 min,the incision length was 4.2 cm,surgical blood loss was 252ml,surgical draining loss was 97ml,the postoperative ambulation time was 1.9 d,the hospital stay was 7.6 d. Complication was noted in one patient, which was the transient nerve root irritation symptom and ceased after treatment. The mean follow-up was 11.8 months. The JOA scores and the lumbocrural pain VSA scores before discharge and of the final follow-up improved than that of preoperation, and the difference was statistically significant(P <0. 01). The average improvement rate of life quality was 85.6% at final follow-up. The intervertebral height increased from( 5.68 ± 1.82) mm to( 10. 01 ± 1.31)mm. [Conclusion] Applying the Quadrant minimally invasive treatment system to treat the lumbar degenerative disease has many advantages such as less damage to the spine stability,less tissue trauma,less bleeding and quicker recovery and so on, beside of those advantages, it is easy to operate and has defined clinical efficacy. All of these suggest the clinical promotion.%[目的]探讨应用Quadrant微创系统治疗腰椎退行性疾病的临床疗效.[方法]对2011年2月~2012年4月本院应用Quadrant微创系统行腰椎融合手术患者34例进行分析,观察手术后各项指标、椎间隙高度恢复及并发症发生情况,并采用日本骨科学会(JOA)评分和疼痛视觉模拟量表(VAS)

    We sought to evaluate the clinical and radiologic efficacy of stand-alone anterior lumbar interbody fusion (ALIF) for low grade degenerative spondylolisthesis, the favoured surgical management approach at our institution. The optimal approach for surgical management of spondylolisthesis remains contentious. We performed a prospective analysis of all consecutive patients with low grade lumbar spondylolisthesis who underwent ALIF between 2009 and 2013 by a single surgeon (n=27). The mean age was 64.9 years with a male to female ratio of 14:13. There were 32 levels operated and the average preoperative spondylolisthesis was 14.8%, which reduced to 6.4% postoperatively and 9.4% at the latest follow-up (p=0001). Postoperative disc height was increased to 175% of preoperative values and was statistically significant (plumbar degenerative spondylolisthesis. Future studies should include adequately powered, prospective, multicentre registry studies with long term follow-up to allow a better assessment of the relative benefits and risks.

    The purpose of this paper is to discuss the capabilities and drawbacks of MR imaging in patients with trauma to the spine and degenerative spinal conditions. In spinal trauma MR imaging is secondary to plain X-ray films and CT because of the greater availability and ease of performance of these techniques and their superior capability for detecting vertebral fractures. Magnetic resonance imaging is useful for detecting ligamentous ruptures and intraspinal mass lesions such as hematoma, and for assessing the state of the spinal cord and prognosis of a cord injury. In degenerative spinal disease the necessity is emphasized of critically evaluating the clinical relevance of any abnormal feature detected, as findings of degenerative pathology are common in individuals without symptoms. Magnetic resonance myelography permits rapid and accurate assessment of the state of the lumbar nerve roots (compressed or not). In the cervical region the quality of the myelographic picture is often degraded in patients with a narrow spinal canal. (orig.) With 10 figs., 14 refs.

    BACKGROUND:Once lumbar degenerative diseases merge with lumbar spinal stenosis, lumbar instability and degenerative scoliosis, surgical therapy is required for corresponding clinical symptoms, and the usage of internal fixators cannot be inevitable. Osteoporosis is rather common in the elderly. Therefore, how to implant stable pedicle screw fixation system in serious osteoporosis patients wil be a big difficulty. In recent years, some studies have proven the biomechanical stability of polymethylmethacrylate augmentation of a cannulated and fenestrated pedicle screw in the vertebral body, so it becomes very hot in the spine surgery. OBJECTIVE: To explore the clinical efficacy of the use of polymethylmethacrylate augmentation of a cannulated and fenestrated pedicle screw fixation for the treatment of lumbar degenerative disease accompanied with osteoporosis. METHODS:Thirty-one patients with lumbar degenerative disease accompanied with osteoporosis from Jun 2008 to Jan 2013 were selected, including 11 males and 20 females with an average age of 73.5 years (range, 65-86 years). There were 14 cases of lumbar degenerative stenosis, 9 of lumbar intervertebral disc herniation combined with segmental instability, 6 of lumbar degenerative spondylolisthesis, and 2 of lumbar degenerative scoliosis. The patients were treated with lumbar canal decompression, fusion and polymethylmethacrylate augmentation of a cannulated and fenestrated pedicle screw fixation according to their clinical features and imaging data. Visual analog scale for pain evaluation was used before and after fixation, the Japanese Orthopaedic Association (JOA) scale was used for assessment of neurological function and life skils before internal fixation and during folow-up. RESULTS AND CONCLUSION:Al cases were folowed up for 40 months (range, 36-48months). No screw breakage, rod breakage, screw extraction, loosening, pseudoarticulation formation, or incision infection was found. The postoperative visual

    Physiotherapeutic management of patients immediately following lumbar spinal surgery is common. However, there is considerable variability in the interventions provided. To assess the effect of peri-operative physiotherapeutic intervention in adults undergoing surgery for the management of degenerative lumbar conditions. The Cochrane Library, Medline, Embase, CINAHL and PEDro were searched from inception to August 2012. Randomised controlled trials investigating physiotherapeutic interventions prior to and immediately following surgery for degenerative lumbar conditions were included. Two reviewers extracted data independently using a standardised form. Risk of bias was assessed using a modified version of the Cochrane Collaboration tool. The quality of evidence was assessed using the GRADE approach, and the treatment effect size was calculated where comparable outcome measures were used across multiple trials. Four studies were included. There is very-low-quality evidence that pre- and post-operative exercise in addition to standard physiotherapeutic care may reduce pain, time taken to achieve post-operative functional milestones, and post-operative time off work. Results from one study indicated that there is no clear benefit or risk of harm from performing either prone or side-lying transfers. Very-low-quality evidence suggests that physiotherapy may improve pain and function following lumbar surgery. Due to low numbers of included studies and variation in the interventions assessed, the current evidence provides limited guidance for physiotherapeutic practice. Further research is required to determine the effectiveness of physiotherapeutic interventions in this population. Copyright © 2014 Chartered Society of Physiotherapy. Published by Elsevier Ltd.

    Highlights: • This systematic literature review summarizes the current knowledge on MR imaging in degenerative disc disease. • Different classification systems for segmental spine degeneration are summarized. • It outlines the diagnostic limitations of MR imaging. - Abstract: Magnet resonance imaging (MRI) is the most commonly used imaging modality for diagnosis of degenerative disc disease (DDD). Lack of precise observations and documentation of aspects within the complex entity of DDD might partially be the cause of poor correlation of radiographic findings to clinical symptoms. This literature review summarizes the current knowledge on MRI in DDD and outlines the diagnostic limitations. The review further sensitizes the reader toward awareness of potentially untended aspects of DDD and the interaction of DDD and endplate changes. A summary of the available classifications for DDD is provided.

    The pharmacological treatment of degenerative joint diseases is restricted essentially to the alleviation of acute symptoms of activated arthropathies. Suitable compounds are the non-steroidal and steroidal antiinflammatory drugs, which however do not allow long-term therapy due to their overall catabolic effects on cartilage metabolism. Since causally acting drugs are not available, the progressive course of the disease cannot be prevented so far. Natural components of the cartilage's matrix, being recommended as so-called chondroprotective drugs, do not fulfill the expectation of a remission of the degenerative process. Indeed, regarding the necessity of multiple local applications of these drugs, they are not superior to antiinflammatory drugs. Provided careful dosing and surveillance of untoward gastrointestinal effects, non-steroidal antiinflammatory agents still are the drugs of first choice.

    Objective To investigate the causes and clinical features of misdiagnosis of lumbar disc degenerative dis-eases. Methods We conducted a retrospective analysis of a hospital database, including all patients admitted to the depart-ment of orthopaedic surgery of General Hospital of PLA Navy, with a diagnosis of lumbar disc degenerative diseases and subse-quent diagnosis of other diseases during January 2007 and December 2011. Results All the patients were found with low back pain syndrome, misdiagnosed as lumbar degenerative diseases including 18 cases of disc herniation, 8 cases of lumbar stenosis, 6 cases of discogenic low back pain, 2 cases of lumbar spondylolisthesis and 2 cases of lumbar joints abnormality. Definite diagnoses were primary spinal tumor (4 cases), metastatic tumor (3 cases), arterial occlusion of lower extremity (3 cases), sacroiliitis (3 cases), lumbar tuberculosis (5 cases), avascular necrosis of femoral head (6 cases), osteoarthrosis of hip (6 cases), etc. All patients underwent specific treatments after the exact diagnosis and showed obvious improvement. Conclusion Because low back pain syndrome may be misdiagnosed as disc degenerative diseases such as inflammation, tumor and blood vessel diseases, at an early stage, therefore a careful understanding of history and neurological examination, including impulse test is mandatory to maximally reduce the misdiagnosis rate.%目的:探讨腰腿痛症候群的背景疾病,以及与腰椎退行性疾病的鉴别诊断要点。方法对我科2007年1月—2011年12月误诊为腰椎退行性疾病36例临床资料进行回顾性分析。结果本组均以腰腿痛症候群为主诉,分别在本院及外院误诊,误诊疾病:腰椎间盘突出症18例,腰椎管狭窄症8例,椎间盘源性下腰痛6例,腰椎滑脱及腰椎小关节紊乱各2例。最终确诊疾病:股骨头缺血性坏死及髋关节骨性关节炎各6例,腰椎结核5例,腰椎管内肿瘤4例,腰椎转移性

  3. Studies on the pathogenesis of degenerative lumbar canal stenosis by computed tomography, 2. Investigation about measurements of the lumbar canal

    Kido, Kenji

    1987-07-01

    To evaluate the significance of measurement parameters for the lumbar canal (LC), a retrospective analysis was made of computed tomography (CT) scans in a total of 129 patients, including 20 with degenerative lumbar canal stenosis (DLCS), 65 with degenerative spondylosis, 21 with disc hernia, and 23 with lumbar pain. The shape of the transverse LC was not reflected by the anteroposterior and transverse diameters of LC, but was somewhat reflected by the transverse area of LC. The transverse area of dural sac (DS) was considered important in determining the degree of stenosis. Regarding the transverse area, the DS correlated more strongly with the LC with soft-tissue windows than that with bone windows. The angle of intervertebral joint was likely to be related to the pathophysiology of the LC. In particular, sagittal tendency was seen at the levels of L3-4 and L4-5 in the DLCS group. There was correlation between the angle of intervertebral joint and the transverse areas of both soft-tissue LC and DS at the levels of L4-5. A multivariate analysis suggested the possibility that the significance of measurement parameters might vary depending on the vertebral level for the lower lumbar spine. The following criteria for indicating DLCS were obtained: 1) a transverse area of less than or equal to 100 mm/sup 2/ for DS or less than or equal to 118 mm/sup 2/ for soft-tissue LC at the levels of L3-4; 2) a transverse area of less than or equal to 90 mm/sup 2/ for DS and an angle of less than or equal to 90 deg for the intervertebral joint at the levels of L4-5; and 3) lateral recess of less than or equal to 3 mm in anteroposterior diameter at the levels of L5-S1.

    there is not any correctly done study that compares the conservative and surgical treatments in the manegement of her-niated lumbar disc. For that reason , we are still triying to find new treatment options in the nonsurgical field of her-niated lumbar disc. When we analize the published results of the spine surgery, we must beard in mind what have been call in the "American Stock and Excahnge" "the bubble of spine surgery". The scientific literature does not show clear evidence in the cost-benefict studies of most instrumented surgical interventions of the spine compare with the conservative treatments. It has not been yet demostrated that fusion surgery and disc replacement are better options than the conservtive treatment. It´s necesary to point out that at present "there are relationships between the industry and back pain and there is also an industry of the back pain" . Nontheless, the "market of the spine surgery" is growing up because patients are demanding solutions for their back problems. The tide of scientific evidence seams to go against of the spinal fusions in the degenerative disc disease, discogenic pain and inespecific back pain. After decades of technological advances in this field, the results of spinal fusions are mediocre. Recent epidemiological studies show that "spinal fusion must be accepted as a non proved or experimental method for the treatment of back pain". The surgical literature on spinal fusion published in the last 20 years following the Cochrane’s method stablish that: 1- this is at least incomplete, not realiable and careless; 2- the instrumentation seems to sligthy increase the fusion rate ; 3- the instrumentation doesn’t improve the clinical results in general, lacking studies in subgroups of patients. We still are needing randomized studies to compare the surgical results with the natural history of the disease, the pacebo effect, or the conservative treatment.

    A number of pathologic changes have been reported in spinal surgery specimens. The frequency of many of these is not well defined. We retrospectively reviewed the histologic features of 985 extradural spinal surgery specimens. Of the cases, 1.6% were identified clinically as synovial cysts. In addition, synovial tissue was seen in another 5.3% of cases, often embedded within disk material. Neovascularization of disk tissue was present in 8.1% of cases, chondrocyte clusters in 18.3%, and calcium pyrophosphate crystals in 2.8%, predominantly within disk material. With the exception of crystal deposits, all of these changes were significantly more common in the lumbar spine. A better understanding of cell-based degenerative changes will become essential with increasing research into cell-based therapies for spinal disk disease. We report data on the frequency of different pathologic changes and describe synovial metaplasia as a reactive change not previously reported.

    Full Text Available Background: Lumbar degenerative spondylolisthesis (LDS is a degenerative slippage of the lumbar vertebrae. We aimed to evaluate the surgical outcome of degenerative spondylolisthesis with neural decompression, pedicular screw fixation, reduction, and posterolateral fusion. Methods: This before-after study was carried out on 45 patients (37 female and 8 male with LDS operated from August 2008 to January 2011. The patients’ pain and disability were assessed by visual analogue scale (VAS and Oswestry disability index (ODI questionnaire. In surgery, we applied distraction force to facilitate slip reduction. All the intra- and postoperative complications were recorded. The paired t-test and Pearson correlation coefficient were used for statistical analysis. Results: The mean age of patients and mean follow-up period were 58.3±3.5 years and 31.2±4.8 months, respectively. The mean slip correction rate was 52.2% with a mean correction loss of 4.8%. Preoperative VAS and ODI improved from 8.8 and 71.6 to postoperative 2.1 and 28.7, respectively. Clinical improvement was more prominent in more reduced patients, but Pearson coefficient could not find a significant correlation. Conclusion: Although spinal decompression with fusion and posterior instrumentation in surgical treatment of the patients with LDS result in satisfactory outcome, vertebral reduction cannot significantly enhance the clinical improvement.

    About one third of lumbar synovial cysts are associated with degenerative spondylolisthesis. Segmental instability is thought to contribute to the pathogenesis and recurrence of synovial cysts and lumbar fusion has been advocated as a treatment of choice in the presence of spondylolisthesis. In patients with spondylolisthesis, minimally invasive resection of lumbar synovial cysts, without fusion, could minimize surgically induced segmental instability while providing good pain relief. Clinical and radiological outcomes of lumbar synovial cyst patients with and without spondylolisthesis were retrospectively compared. Pain outcomes were assessed with modified Macnab criteria. Fifty-three patients (18 with grade 1 spondylolisthesis) underwent minimally invasive synovial cyst resection and all had either excellent or good pain outcome at ≤ 8 post- operative weeks (P = 1.000, n = 53). At > 8 post-operative weeks (mean (SD) follow-up of 200 (175) weeks), excellent or good outcomes were noted in 89% of patients without spondylolisthesis and in 75% of patients with spondylolisthesis (P = 0.425, n = 40). Four patients developed a new grade 1 spondylolisthesis at a mean follow-up of 2.6 ± 2.1 years. Nine patients were assessed for spondylolisthesis measurements at 1.2 ± 1.3 years of follow up and no significant difference was observed (5 ± 0 vs 5 ± 1 mm; P = 0.791). Two patients without spondylolisthesis and none of the patients with spondylolisthesis had a synovial cyst recurrence. Patients with concomitant lumbar degenerative spondylolisthesis and synovial cyst can have good short- and long-term clinical outcomes with minimally invasive surgery without fusion. Post-operative segmental instability does not appear to be significant in patients with spondylolisthesis. All patients included in this article signed an informed consent for the use of their medical information for research.

The height of the intervertebral disc with osteochondrosis below at all levels by an average of 25% of its value in the range 5,27±0,19 to 6,13±0,17mm, while the normal disc height varies from 6,88±030 to 9,36±0,28mm. The area of intervertebral holes normally ranging from 103,29±5,78 to 127,99±5,92mm2, with osteochondrosis aperture area is reduced to a greater extent by decreasing the vertical diameter in comparison with the horizontal. Conclusion. For the studied parameters characteristic topographic variability has been determined. The maximum values parameters are marked at the top of the lumbar lordosis, at chest height, lumbar and lumbosacral junctions sizes are reduced. In osteochondrosis the intervertebral disc height and the height of lumbar vertebral bodies are reduced; intervertebral foramina area is also reduced to a greater extent by reducing the vertical diameter than the horizontal one.

    Somatosensory profiling in affected and non-affected body regions can strengthen our insight regarding the underlying pain mechanisms, which can be valuable in treatment decision making and to improve outcomes, in patients with degenerative lumbar spine disorders pre-surgery. The aim was to describe somatosensory profiles in patients with degenerative lumbar spine disorders, to identify the proportion with altered somatosensory profile, and to analyze demographic characteristics, self-reported function, pain, and health pre- and 3 months post-surgery. In this prospective cohort study in a Spine Clinic, 105 patients scheduled for surgery for spinal stenosis, disc herniation, degenerative disc disease, or spondylolisthesis were consecutively recruited. Exclusion criteria were; indication for acute surgery or previous surgery at the same spinal level or severe grade of pathology. Quantitative sensory testing (QST) and self-reported function, pain, and health was measured pre- and 3 months post-surgery. The somatosensory profile included cold detection threshold, warmth detection threshold, cold pain threshold, heat pain threshold and pressure pain threshold in affected and non-affected body regions. On a group level, the patients' somatosensory profiles were within the 95% confidence interval (CI) from normative reference data means. On an individual level, an altered somatosensory profile was defined as having two or more body regions (including a non-affected region) with QST values outside of normal ranges for reference data. The 23 patients (22%) with altered somatosensory profiles, with mostly loss of function, were older (P = 0.031), more often female (P = 0.005), had higher back and leg pain (P = 0.016, 0.020), lower mental health component summary score (SF-36 MCS) (P = 0.004) and larger pain distribution (P = 0.047), compared to others in the cohort. Post-surgery there was a tendency to worse pain, function and health in the group with

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.

    As the life span and proportion of people over 65 years increase, the incidence of degenerative lumbar spine stenosis grows proportionally. Various parameters of the spinopelvic relationships are used to predict surgical treatment outcomes in patients with degenerative spine diseases. There are no unified protocols for evaluation, in terms of the sagittal balance, of surgical treatment outcomes in elderly patients. To study the impact of sagittal balance parameters on the life quality of elderly and senile patients after surgery for degenerative stenosis of the lumbar spine. The study included 109 patients. Decompression was performed in the first group of 53 patients. Decompression and stabilization were performed in the second group of 27 patients. In the third group of 29 patients, XLIF indirect decompression, scoliosis correction, reconstruction of disturbed spinopelvic relationships, and stabilization were carried out. We evaluated the following sagittal balance parameters: pelvic incidence (PI), sacral slope (SS), pelvic tilt (PT), lumbar lordosis (LL), and PI minus LL (PI-LL). The quality of life indicators were assessed using VAS, ODI, and SF36 scores. In the first group, there were not statistically significant differences for PT≤20° and PT>20°. A statistically significant change in the PI-LL parameter (p=0.0263) was in the first group. A decrease in PI-LL was accompanied by regression of pain (p20° as well as PI-LL≤10° and PI-LL>10 in the postoperative period. In the third group, postoperative improvement in PT (p=0.0002) and PI-LL (p=0.0008) parameters was accompanied by a decrease in pain in the legs (p=0.0002) and lumbar spine (p=0.0001). Improvement in the quality of life indicators in 48.6% of cases was achieved by decompression only; the sagittal balance parameters had no significant impact on quality of life. In 24.8% of cases, improvement in the quality of life indicators was achieved by decompression and stabilization because the dominant

    Full Text Available Degenerative valvular disease or endocardiosis is the most common cardiovascular pathology in dogs. It is characterized by regurgitation of blood into the atria with decreased cardiac output, leading to volume overload with eccentric hypertrophy and congestive heart failure. This report describes the clinical and autopsy findings of a dog, suggestive of valvular endocardiosis. The patient was admitted to the outpatient Veterinary Clinic “Carlos Martínez Hoyos” at the University of Nariño (Pasto, Colombia. His owner said the dog was sick for two months, with signs of respiratory disease, weight loss, and decay. Clinical examination showed very pale mucous membranes, inspiratory dyspnea, rale, split S2, grade 4 mid-systolic murmur of regurgitation, and abdominal dilatation with sign of positive shock wave. Necropsy evidenced plenty of translucent watery material in the abdominal, chest and pericardium cavity, severely enlarged and rounded heart with thickened atrioventricular valves, moderate reduction in liver size and signs of lobulation, severely diminished and pale kidneys with irregular surface showing the presence of multiple cystic areas in corticomedullary region. Samples were taken from these tissues and fixed in 10% buffered formalin to be processed for histopathological analysis at the Laboratory of Pathology at the University of Nariño, using hematoxylin and eosin stain. This way, degenerative valvular disease was diagnosed.

    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.

    Adult degenerative scoliosis associated with lumbar stenosis has become a common issue in the elderly population. But its surgical management is on debating. The main issue condenses on the management priority of scoliosis or stenosis. This study is to investigate surgical management strategy and outcome of adult degenerative scoliosis associated with lumbar stenosis. Between January 2003 and December 2010, 108 patients were admitted to the authors' institution for adult degenerative scoliosis associated with lumbar stenosis. They were divided into 3 groups based on the symptom. Then the surgical management was carried out. The clinical outcome was evaluated according to the Oswestry Disability Index (ODI) and Scoliosis Research Society-22 score (SRS-22 score) at follow up. Group 1 was with primary lumbar stenosis symptom, local decompression and short fusion were performed. Group 2 was with compensated spinal imbalance symptom, local decompression of the symptomatic spinal stenosis and short fusion were performed. Group 3 was with primary spinal imbalance, correction surgery and long fusion were performed. For Group 1, the ODI scores declined from 62.5 ± 4.2 preoperatively to 21.8 ± 2.5 at final follow up, the SRS-22 scores decreased from 44.8 ± 3.2 preoperatively to 70.9 ± 6.0 at final follow up. For Group 2, the ODI and SRS-22 scores were 73.4 ± 8.4 and 40.8 ± 8.5 before the surgery, declined to 22.4 ± 4.2 and 73.2 ± 7.9 at final follow up. For Group 3, the ODI and SRS-22 scores were 73.4 ± 4.9 and 45.3 ± 6.4 before surgery, declined to 30.4 ± 8.9 and 68.8 ± 8.1 at final follow up. It was effective to perform decompression and short fusion for Group 1 and correction surgery and long fusion for Group 3. For Group 2, the compensated imbalance symptom was always provoked by the symptomatic lumbar stenosis. The cases in the Group 2 got well clinical improvements after local surgical intervene on the

    OBJECTIVE Several biomechanical studies have demonstrated the favorable mechanical properties of the cortical bone trajectory (CBT) screw. However, no reports have examined surgical outcomes of posterior lumbar interbody fusion (PLIF) with CBT screw fixation for degenerative spondylolisthesis (DS) compared with those after PLIF using traditional pedicle screw (PS) fixation. The purposes of this study were thus to elucidate surgical outcomes after PLIF with CBT screw fixation for DS and to compare these results with those after PLIF using traditional PS fixation. METHODS Ninety-five consecutive patients underwent PLIF with CBT screw fixation for DS (CBT group; mean followup 35 months). A historical control group consisted of 82 consecutive patients who underwent PLIF with traditional PS fixation (PS group; mean follow-up 40 months). Clinical status was assessed using the Japanese Orthopaedic Association (JOA) scale score. Fusion status was assessed by dynamic plain radiographs and CT. The need for additional surgery and surgery-related complications was also evaluated. RESULTS The mean JOA score improved significantly from 13.7 points before surgery to 23.3 points at the latest follow-up in the CBT group (mean recovery rate 64.4%), compared with 14.4 points preoperatively to 22.7 points at final follow-up in the PS group (mean recovery rate 55.8%; p fusion was achieved in 84 patients from the CBT group (88.4%) and in 79 patients from the PS group (96.3%, p > 0.05). Symptomatic adjacent-segment disease developed in 3 patients from the CBT group (3.2%) compared with 9 patients from the PS group (11.0%, p fusion rate tended to be lower in the CBT group than in the PS group, although the difference was not statistically significant between the 2 groups.

    To assess the inter- and intra-reader agreement of commonly used quantitative and qualitative image parameters for the assessment of degenerative lumbar spinal canal stenosis (LSS) by magnetic resonance imaging (MRI). In this ethical board approved cross-sectional multicenter study, MRI of 100 randomly selected patients (median age 72.5 years, 48 % female) of the prospective Lumbar Stenosis Outcome Study (LSOS) were evaluated by two independent readers. A set of five previously published core imaging parameters as well as nine qualitative and five quantitative additional parameters regarding LSS and degenerative changes of the lumbar spine were assessed to calculate κ and intraclass correlation coefficients (ICC) for the inter-reader agreement. Additional repeated image evaluations were performed by one reader to calculate the intra-reader agreement. κ values for the core image parameters ranged between 0.42 (compromise of the foraminal zone) and 0.77 (relation between fluid and cauda equina) for inter-reader agreement and between 0.59 (compromise of the foraminal zone) and 0.8 (compromise of the central zone) for intra-reader agreement. The inter-reader agreement for the non-core parameters showed κ values of 0.27-0.69 and ICC values of 0.46-0.85. The intra-reader agreement showed κ values of 0.53-0.69 and ICC values of 0.81-0.88. The inter- and intra-reader agreement of commonly used quantitative and qualitative image parameters for the assessment of LSS showed quite a variability with previously defined core parameters having good to excellent inter- and intra-reader agreements.

    This study reviews the outcomes and revision rates of degenerative lumbar fusion surgery using cortical trajectory pedicle screws in lieu of traditional pedicle screw instrumentation. Pedicle screw fixation can be a challenge in patients with low bone mineral density. Wide posterior approaches to the lumbar spine exposing lateral to the facet joints and onto transverse processes causes an additional degree of muscular damage and blood loss not present with a simple laminectomy. A cortical bone trajectory pedicle screw has been proposed as an alternative to prevent screw pullout and decrease the morbidity associated with the wide posterior approach to the spine. We present a series of eight consecutive patients using a cortical bone trajectory instead of traditional pedicle screw fixation for degenerative conditions of the lumbar spine. A retrospective review of our institutional registry data identified eight patients who had cortical screws placed with the assistance of O-arm Stealth navigation (Medtronic Sofamor Danek, Memphis, TN, USA) from 2010-2013. We analyzed the need for revision, the maintenance of reduction and the incidence of screw pullout or breakage. Our review demonstrated that two of eight patients were revised at an average of 12months. The reasons for these revisions were pseudarthrosis and caudal adjacent segment failure. All patients who were revised had frank screw loosening. We present early clinical results of a new technique that has been shown to have a better fixation profile in laboratory testing. Our less than favorable early clinical results should be interpreted with caution and highlight important technical issues which should be considered. Copyright © 2015 Elsevier Ltd.

    Both forelimbs of rats were amputated, and these rats were kept in the custom-made cages that kept the rats in prolonged upright posture. Pathologic changes were observed in the lumbar spine at different time points after the surgery. To investigate the effect of upright posture on intervertebral discs of rat lumbar spine. Previous studies have shown that increased axial forces on the spine can decrease the height of the intervertebral disc, but there are no data to indicate whether or not long-term and repeated assumption of the upright posture could result in degenerative changes. The forelimbs of 30 rats were amputated when they were 1-month old. These rats were kept in the custom-made cages and were forced to stand upright on their hind-limbs and tails to obtain water and food. Normal rats of the same ages kept in regular cages were used as control. The rats were killed at 5, 7, and 9 months after the surgery, and the intervertebral discs samples of lumbar spine were harvested for histologic and immunohistochemical studies. Total RNA isolated from these samples was used for real-time PCR of type II collagen (Col2alpha1), type X collagen (Col10alpha1), matrix metalloproteinase-13 (MMP-13), aggrecan, and disintegrin and metalloproteinase with thrombospondin motifs 5 (ADAMTS-5). RESULTS.: Histologic analysis showed degenerative changes of the intervertebral discs after surgery such as disordered collagen structure of endplate cartilage, fragmentation of annulus fibrosus, and decreased height of disc. Immunostaining revealed decreased protein level of type II collagen and increased protein expression of type X collagen. Real-time PCR showed upregulated expression of MMP 13, ADAMTS-5, and Col10alpha1 mRNA and downregulated mRNA expression of Col2alpha1 and aggrecan. Long-term and repeated assumption of the upright stance accelerates disc degeneration in rats.

    Lumbar spinal stenosis is a common diagnosis in elderly individuals, and the rates of surgery have risen all over the world. The optimal approach to provide satisfactory decompression and minimize complications for lumbar spinal stenosis remains controversial. The purpose of this study was to evaluate the surgical outcome of interspinous spacers versus decompressive laminectomy in the management of degenerative lumbar canal stenosis. Our prospective, comparative study included 2 groups of patients who were operated on in Ain Shams University Hospitals between January 2010 and December 2014. In the first group, 28 patients underwent decompression and additional implantation of an interspinous spacer (ISP). In the second group, 25 patients underwent decompressive laminectomy (DL). Our statistical results revealed no significant difference in outcome between the 2 groups regarding visual analog scale score for leg pain and Oswestry Low Back Pain Disability Index. However, the improvement (visual analog scale score) for back pain was better in the DL group. Complication and reoperation rates were higher in the ISP group. Although decompression and additional implantation of an ISP are safe procedures, they do not show better improvement in clinical outcome as compared with decompressive laminectomy.

    助于早期功能恢复.%Objectives: To compare clinical outcomes of minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF group) via MAST Quadrant retractor vs conventional posterior open surgery(open group) for degenerative lumbar spine disease. Methods: From March 2008 to June 2010, 80 patients with single-level lumbar degenerative disease and failed with conservative treatment were enrolled in this study. All cases were divided into two groups randomly, with 40 patients in each group. There was no significant difference in age, gender, body weight, clinical diagnosis or the segment between the two groups (P>0.05). Minimally invasive transforaminal lumbar interbody fusion via MAST Quadrant retractor or the conventional posterior open surgery was performed randomly. The operation time, blood loss, postoperative drainage, hospital stay, creatine phos-phokinase(CPK) in serum, MRI-T2 relaxation time, visual analogue scores (VAS) for back and leg pain, Os-westry disability index(ODl), and fusion rate by 24-36 months follow-up(mean time, 29 months) between two groups were compared. Results: The MIS-TLIF group had similar operation time to the open surgery group (141.0±27.3min vs 139.5±33.7min, P>0.05). Intraoperative blood loss, postoperative drainage in MIS-TLIF group was 268.0±122.2ml and 25.6±32.4ml, which was significantly less than 370.0±147.1ml and 277.8± 167.4ml of the open group, respectively (P0.05). The CPK levels were significantly higher at 1, 3, 5 days after surgery(P0.05). Conclusions: Minimally invasive transforaminal lumbar interbody fusion via MAST Quadrant retractor surgery and conventional posterior open surgery both can achieve a good short-term efficiency, but the former surgery had less soft tissue intervention, and conducive to early functional recovery.

    Degenerative lumbar scoliosis(DLS),as one of common degenerative spinal diseases, is common among senior patients. The incidence of DLS is rising, and is becoming a common disease in spine surgery clinics. DLS is a major cause of back pain, leg pain and intermittent claudication of elderly people. Therefore, the primary purpose of the treatment of DLS is to relieve pain and to improve quality of life. Patients of DLS often have other chronic diseases, so under this condition.As for the surgical treatment, options such as simply decompression, extreme lateral interbody fusion, decompression combined with long-segment fixation, internal fixation combined with short stage decompression can be applied based on the size of Cobb angle and the basic conditions of the patients’ body. This article will elaborate on different treatment options.%退行性腰椎侧凸(Degenerative lumbar scoliosis, DLS)作为一种脊柱常见退变性疾病,多见于中老年患者。发病率呈上升趋势,逐渐成为脊柱外科临床常见疾病,是引起老年人腰痛、下肢痛和间歇性跛行的一个重要原因。解除疼痛、提高生活质量成为治疗该 DLS 的首要目的。根据不同的病情,此类疾病的好发人群常伴其他慢性疾病。手术治疗根据Cobb 角的大小、患者身体基础条件等选择单纯减压、极外侧椎间融合术、减压联合长节段内固定、减压联合短节段内固定治疗。本文根据不同的治疗方案进行阐述。

    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 lordosis mismatch. In type A spino-pelvic alignment, 25.5 % of patients underwent revision surgery for 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

    Several papers have studied the degenerative changes of endplates, but there are no publications referring to the Mexican population. The purpose of the study is to report the incidence of Modic degenerative changes in the patients seen at the Spine Service, Monterrey Regional ISSSTE Hospital. Specific objectives are: to describe the type of Modic change and the most frequent location, to describe the degeneration patterns and to report the incidence of the various diagnoses made during 2009. Incidence study using the MRI records at the Radiology Department, Monterrey Regional ISSSTE Hospital, interpreted blindly and independently by two observers. A total of 240 lumbar spine MRIs were reviewed, for a total of 1,200 intervertebral spaces. They were divided by age groups. Group I included 16 patients, Group II 32, Group III 80, and Group IV 112. No patients in Group I had Modic changes. Four patients (12.5%) in Group II had type II Modic changes with 25% involvement of L4-L5 (10%); 32% of Group IV patients had changes, with L5-S1 as the most affected level. Most Modic changes (85%) were located in L4-L5 and L5-S1, with the latter as the most frequently affected level. Type I represented 5%, Type II 30%, and Type III 65%. The percentage of patients with Modic changes increased with age, which confirms that degenerative changes are age related. Morphologic disc changes are expressed as the percentage of affected patients in each group. Besides the severity of degeneration, the number of affected levels also increases with age. Thirty percent of patients ages 30-39 years have one or two degenerated levels, while 50% of those over age 50 have 3 or more degenerated levels. The most frequently degenerated level was L5-S1, followed by L4-L5 and L3-L4. The most frequent degeneration pattern was lower segment degeneration (L4-L5, L5-S1). A small proportion of patients over age 50 (4%) did not have disc degeneration, suggesting that age is not the only factor that determines

    The authors investigate the correlation between thoracic and lumbar curves in patients with degenerative flat back syndrome, and demonstrate the predictability of spontaneous correction of the thoracic curve and sacral angle after surgical restoration of lower lumbar lordosis. The cases of 28 patients treated with combined anterior and posterior spinal arthrodesis were retrospectively reviewed. Inclusion criteria included loss of lower lumbar lordosis resulting in sagittal imbalance. Total lumbar lordosis, thoracic kyphosis, sacral slope, and C-7 plumb line length were measured on pre- and postoperative lateral views of the whole spine. Postoperative changes in thoracic kyphosis, sacral slope, and length of the C-7 plumb line were measured and evaluated according to extent of lumbar lordosis restoration. The mean (+/- standard deviation) preoperative sagittal imbalance was 64.6 +/- 63.2 mm, which improved to 15.8 +/- 20.7 mm after surgery (p sagittal alignment and balance. Surgical restoration of lumbar lordosis results in predictable spontaneous correction of the thoracic curve and sacral slope in patients with degenerative flat back syndrome.

    Lumbar degenerative kyphosis (LDK) is characterized by sagittal imbalance resulting from a loss of lumbar lordosis (LL). The pelvic incidence (PI) regulates the sagittal alignment of the spine and pelvis. The purpose of this study is to evaluate the spinopelvic parameters in patients with LDK and to compare them with those of a normal population. A cross-sectional study. The selected patients showed characteristic clinical features of LDK. As control group, asymptomatic volunteers without spinal pathology were recruited. Full-length radiographs of the spine in the anteroposterior and lateral planes were taken, extending from the base of the skull to the proximal femur. Pelvic incidence, sacral slope (SS), pelvic tilt (PT), main thoracic kyphosis (TK), thoracolumbar junction (TLJ), LL, and sagittal vertical axis (SVA) were evaluated. In terms of PI, the patient and control groups were divided into three groups: low (PI≤45°), middle (45°60°). All the spinopelvic parameters were compared between each group and between the patient and control groups in each group. The correlations between each of the parameters were analyzed. We evaluated 172 patients with symptomatic LDK and 39 healthy volunteers. The number of LDK patients with low, middle, and high PI groups were 44 (25.6%), 72 (44.8%), and 51 (29.6%), respectively. In the control group, the number of low, average, and high PI patients were 18 (46.2%), 15 (38.5%), and 6 (15.4%), respectively. In the control group, PI determined all spinopelvic parameters except SVA. In the LDK group, PI also determined spinopelvic parameters except for TK and SVA. Lumbar degenerative kyphosis with low PI was associated with pronounced kyphosis in LL and TLJ; LDK with a high PI was associated with relatively preserved lordosis in LL with a flat or lordotic TLJ. In terms of pelvic parameters, low PI showed flattened SS and low PT, whereas high PI showed steep SS and high PT. The results of this study suggest the importance of the

    Full Text Available Retinal degenerative diseases are major causes of vision loss and blindness worldwide and are characterized by chronic and progressive neuronal loss. One common feature of retinal degenerative diseases and brain neurodegenerative diseases is chronic neuroinflammation. There is growing evidence that retinal microglia, as in the brain, become activated in the course of retinal degenerative diseases, having a pivotal role in the initiation and propagation of the neurodegenerative process. A better understanding of the events elicited and mediated by retinal microglia will contribute to the clarification of disease etiology and might open new avenues for potential therapeutic interventions. This review aims at giving an overview of the roles of microglia-mediated neuroinflammation in major retinal degenerative diseases like glaucoma, age-related macular degeneration, and diabetic retinopathy.

    Degenerative spondylolisthesis is common in adults. No consensus is available about the analysis or surgical treatment of degenerative spondylolisthesis. In 2013, the French Society for Spine Surgery (Societe francaise de chirurgie du rachis) held a round table discussion to develop a classification system and assess the outcomes of the main surgical treatments. A multicentre study was conducted in nine centres located throughout France and Luxembourg. We established a database on a prospective cohort of 260 patients included between July 2011 and July 2012 and a retrospective cohort of 410 patients included in personal databases between 2009 and 2013. For patients in the prospective cohort clinical assessments were performed before and after surgery using the self-administered functional impact questionnaire AQS, SF12, and Oswestry Disability Index (ODI). Type of treatment and complications were recorded. Antero-posterior and lateral full-length radiographs were used to measure lumbar lordosis (LL), segmental lordosis (SL), pelvic incidence (PI), pelvic tilt (PT), sagittal vertical axis (SVA), and percentage of vertebral slippage. Mean follow-up was 10 months. We started a randomised clinical trial comparing posterior fusion of degenerative spondylolisthesis with versus without an inter-body cage. 60 patients were included, 30 underwent 180° fusion and 30 underwent 360° fusion using an inter-body cage implanted via a transforaminal approach. We evaluated the quality of neural decompression achieved by minimally invasive fusion technique. In a subgroup of 24 patients computed tomography (CT) was performed before and after the procedure and then compared. Mean age was 67 years and 73% of degenerative spondylolisthesis were located at L4-L5 level. The many surgical procedures performed in the prospective cohort were posterior fusion (39%), posterior fusion combined with inter-body fusion (36%), dynamic stabilization (15%), anterior lumbar fusion (8%), and postero

    A retrospective, observational study. The aim of this study was to determine the utilization of various treatment modalities in the management of degenerative spondylolisthesis within Medicare beneficiaries. Degenerative lumbar spondylolisthesis is a condition often identified in symptomatic low back pain. A variety of treatment algorithms including physical therapy and interventional techniques can be used to manage clinically significant degenerative spondylolisthesis. This study utilized the 5% national sample of Medicare carrier claims from 2000 through 2011. A cohort of beneficiaries with a new International Classification of Diseases 9th edition (ICD-9) diagnosis code for degenerative lumbar spondylolisthesis was identified. Current procedural terminology codes were used to identify the number of procedures performed each year by specialty on this cohort. A total of 95,647 individuals were included in the analysis. Average age at the time of initial diagnosis was 72.8 ± 9.8 years. Within this study cohort, spondylolisthesis was more prevalent in females (69%) than males and in Caucasians (88%) than other racial demographics. Over 50% of beneficiaries underwent at least one injection, approximately one-third (37%) participated in physical therapy, one in five (21%) underwent spinal surgery, and one-third (36%) did not utilize any of these interventions. Greater than half of all procedures (124,280/216,088) occurred within 2 years of diagnosis. The ratio of focal interventions (transforaminal and facet interventions) to less selective (interlaminar) procedures was greater for the specialty of Physical Medicine and Rehabilitation than for the specialties of Anesthesiology, Interventional Radiology, Neurosurgery, and Orthopedic Surgery. The majority of physical therapy was dedicated to passive treatment modalities and range of motion exercises rather than active strengthening modalities within this cohort. Interventional techniques and physical therapy are

    Full Text Available Etiology of degenerative joint diseases Etiology of degenerative joint diseases is still not clearly understood and there is no specific management for this group of diseases. Various pathological conditions cause damage of the articular cartilage and lead to clinically and radiographically recognized impairment. Biomechanical, metabolic, genetic factors inflammation and other risk factors contribute to development of osteoarthrosis. Pathophysiology of degenerative joint diseases Osteoarthrosis is characterized by progressive erosion of articular cartilage and bone overgrowth at the joint margins. Cartilage integrity requires balance between synthesis and degradation of matrix components. Chondrocytes react to various mechanical and chemical stresses in order to stabilize and restore the tissue. Failures in stabilizing and restoring the tissue lead to cartilage degeneration that may be irreversibile. For better understanding of conservative management of degenerative joint diseases it is important to know the impact of pathophysiology mechanisms on development of degenerative joint diseases. There is great variability in the rate of progression of erosive processes in articular cartilage in clinical radiographic signs and course of the disease. This is in relation with many factors, as well as with management and response to therapy. Treatment of degenerative joint diseases Treatment should vary depending on the severity of disease and patient's expectations and level of activity. Besides analgesic and anti-inflammatory drugs, conventional and not conventional treatment and techniques can be used for management of osteoarthrosis. Physical therapy and exercises are very important for maintaining muscle strength, joint stability and mobility, but should be closely monitored for optimal efficacy.

    The goal of surgical treatment for degenerative lumbar spinal stenosis (LSS) is to effectively relieve the neural structures by various decompressive techniques. Microendoscopic decompressive laminotomy (MEDL) is an attractive option because of its minimally invasive nature. The aim of prospective study was to investigate the effectiveness of MEDL by evaluating the clinical outcomes with patient-oriented scoring systems. Sixty consecutive patients receiving MEDL between December 2005 and April 2007 were enrolled. The indications of surgery were moderate to severe stenosis, persistent neurological symptoms, and failure of conservative treatment. The patients with mechanical back pain, more than grade I spondylolisthesis, or radiographic signs of instability were not included. A total of 53 patients (36 women and 17 men, mean age 62.0) were included. Forty-five patients (84.9%) were satisfied with the treatment result after a follow-up period of 15.7 months (12-24). The clinical outcomes were evaluated with the Oswestry disability index (ODI) and the Japanese Orthopedic Association (JOA) score. Of the 50 patients providing sufficient data for analysis, the ODI improved from 64.3 +/- 20.0 to 16.7 +/- 20.0. The JOA score improved from 9.4 +/- 6.1 to 24.2 +/- 6.0. The improvement rate was 73.9 +/- 30.7% and 40 patients (80%) had good or excellent results. There were 11 surgical complications: dural tear in 5, wrong level operation in 2, and transient neuralgia in 4 patients. No wound-related complication was noted. Although the prevalence of pre-operative comorbidities was very high (69.8%), there was no serious medical complication. There was no post-operative instability at the operated segment as evaluated with dynamic radiographs at final follow-up. We concluded that MEDL is a safe and very effective minimally invasive technique for degenerative LSS. With an appropriate patient selection, the risk of post-operative instability is minimal.

    We retrospectively reviewed patient charts to compare the approach-related (convex versus concave) neurological complications and magnitude of correction in patients undergoing lateral lumbar interbody fusion (LLIF). It is yet to be quantitatively determined if correction of adult degenerative scoliosis from either side of the curve apex using a LLIF results in a reduction in complications and/or improved corrective ability. The inclusion criteria for this study were patients who underwent a LLIF for adult degenerative thoracolumbar scoliosis and had the LLIF prior to any other supplemental procedures. Patients were grouped based on the approach toward the curve apex concavity (CAVE) or the convexity (VEX). Standard coronal and sagittal radiographic measurements were made. Neurological complications and reoperation indications were also recorded. We included 32 patients for review (CAVE: 17; VEX: 15) with a mean age of 65.5 years±a standard deviation of 10.2, and mean follow-up of 17.0 months±15.7. There were eight postoperative neurological complications in eight patients (25.0%), and seven reoperations for six patients (18.8%; CAVE: 4/17 [23.5%]; VEX: 2/15 [13.3%]). The CAVE group had 6/17 neurological complications (35.3%; four ipsilateral and two contralateral to approach side) and VEX had 2/15 (13.3%; one ipsilateral and one bilateral to approach side; p>0.05). All patients significantly improved in the mean regional and segmental Cobb angles (p0.05). There were no significant differences between the groups for any of the radiographic parameters measured (p>0.05). Approaching the curve apex from either the concave or convex side resulted in significant improvements. The concave approach was associated with more postoperative neurological complications.

      Objective To explore the value of plain film and CT in diagnosing the lumbar degenerative spondylolisthesis. Methods We colected 92 cases of lumbar degenerative spondylolisthesis and made a retrospective analysis on the results of plain film and CT. Results Within degree I, the lumbar degenerative spondylolisthesis was most likely to occur on the fourth lumbar vertebra, together with certain kind of vertebral degeneration. The plain film was the simplest and most effective way to directly demonstrate the disease. The advantage of CT was that the changes in intervertebral discs, duralsca, articular process and spinal canal could be showed clearly. Conclusion The combination of plain film and CT does play an important role in the diagnosis and treatment of lumbar degenerative spondylolisthesis.%  目的探讨X线平片和CT对颈椎退变椎间孔变形原因的诊断价值.方法收集颈椎退变椎间孔变形86例,对其X线平片和CT进行回顾性分析.结果颈椎退变椎间孔变形好发于C3~7,以C4~6发病率最高,多为钩椎关节及关节突关节的退行性变.X线平片能直观地显示颈椎椎间孔形态,是诊断本病最简单而有效的方法,而CT能清楚显示椎间盘、硬膜囊、关节突、钩椎关节和椎管内外结构的变化.X线平片及CT结合可清楚地显示小关节的解剖结构及病理改变,对颈椎椎间孔变形原因的诊断具有较高价值,为临床的诊断和治疗提供了可靠的影像学依据.

    This study aimed to analyze the effect of patient positions on the lordosis and scoliosis of patients with degenerative lumbar scoliosis (DLS).Seventy-seven patients with DLS were retrospectively analyzed. We measured lordosis and Cobb's angle on preoperative upright x-rays and magnetic resonance imagings in supine position. The lordosis and scoliosis of surgical segments in intraoperative prone position were measured on intraoperative radiographs of 20 patients to compare with that in standing position. Paired t tests were performed to investigate the parameters of the sample.From standing to supine position the whole lordosis increased (29.2 ± 15.7 degree vs. 34.9 ± 11.2 degree), and the whole scoliosis decreased (24.3 ± 11.8 degree vs. 19.0 ± 10.5 degree); 53 of 77 (68.8%) cases had increased lordosis, and 67 of 77 (87%) cases had decreased scoliosis. The lordosis of surgical segments in standing position had no difference with that in intraoprerative prone position. But in changing from supine/standing position to intraoprerative prone position, the scoliosis of surgical segments decreased (14.7 ± 9.4 degree vs. 11.4 ± 7.0 degree; 19.0 ± 11.8 degree vs. 11.4 ± 7.0 degree, respectively), and 18 of 20 (90%) cases had decreased scoliosis in intraoperative prone position than that in standing position.Compared with standing position in DLS patients, supine position increased lordosis and reduced scoliosis, and intraoperative prone position reduced scoliosis significantly. When evaluating the severity of DLS and making preoperative surgical plans, lumbar lordosis in supine position should also be evaluated in addition to upright x-ray, and the effects of different positions should be taken into consideration to reduce deviation.

    Full Text Available Objective. To date, there is still no consensus on the treatment of spinal degenerative disease. Current surgical techniques to manage painful spinal disorders are imperfect. In this paper, we aimed to evaluate the prospective results of posterior transpedicular dynamic stabilization, a novel surgical approach that skips the segments that do not produce pain. This technique has been proven biomechanically and radiologically in spinal degenerative diseases. Methods. A prospective study of 18 patients averaging 54.94 years of age with distant spinal segment degenerative disease. Indications consisted of degenerative disc disease (57%, herniated nucleus pulposus (50%, spinal stenosis (14.28%, degenerative spondylolisthesis (14.28%, and foraminal stenosis (7.1%. The Oswestry Low-Back Pain Disability Questionnaire and visual analog scale (VAS for pain were recorded preoperatively and at the third and twelfth postoperative months. Results. Both the Oswestry and VAS scores showed significant improvement postoperatively (P<0.05. We observed complications in one patient who had spinal epidural hematoma. Conclusion. We recommend skipping posterior transpedicular dynamic stabilization for surgical treatment of distant segment spinal degenerative disease.

    This study intends to develop a method of quantitative sagittal balance parameters assessment, based on a geometrical model of lumbar spine and sacrum. One hundred eight patients were divided into 2 groups. In the experimental group have been included 59 patients with lumbar spinal stenosis on L1-5 level. Forty-nine healthy volunteers without history of any lumbar spine pathlogy were included in the control group. All patients have been examined with supine MRI. Lumbar lordosis has been adopted as circular arc and described either anatomical (lumbar lordosis angle), or geometrical (chord length, circle segment height, the central angle, circle radius) parameters. Moreover, 2 sacral parameters have been assessed for all patients: sacral slope and sacral deviation angle. Both parameters characterize sacrum disposition in horizontal and vertical axis respectively. Significant correlation was observed between anatomical and geometrical lumbo-sacral parameters. Significant differences between stenosis group and control group were observed in the value of the "central angle" and "sacral deviation" parameters. We propose additional parameters: lumbar coefficient, as ratio of the lordosis angle to the segmental angle (Kl); sacral coefficient, as ratio of the sacral tilt (ST) to the sacral deviation (SD) angle (Ks); and assessment modulus of the mathematical difference between sacral and lumbar coefficients has been used for determining lumbosacral balance (LSB). Statistically significant differences between main and control group have been obtained for all described coefficients (p = 0.006, p = 0.0001, p = 0.0001, accordingly). Median of LSB value of was 0.18 and 0.34 for stenosis and control groups, accordingly. Based on these results we believe that that spinal stenosis is associated with an acquired deformity that is measureable by the described parameters. It's possible that spinal stenosis occurs in patients with an LSB of 0.2 or less, so this value can be predictable

    The magnetic resonance imaging findings recorded in patients after surgery for degenerative disc disease in the lumbar and cervical spine are discussed in comparison with conventional radiographs and computed tomography findings. In the lumbar spine normal postoperative findings in the immediate postoperative period can be demonstrated by MR imaging. Contrast-enhanced MR imaging can differentiate disc herniation from postoperative scar formation with a greater degree of confidence than other imaging modalities. MR imaging improves differentiation between other causes of failed back syndrome such as postoperative hematoma and infection, lateral spinal stenosis and arachnoiditis. In the cervical spine types of operative approaches, the appearance of bony stenosis and disc herniations by MR imaging are discussed. Computer tomography still has a role in the assessment of osseous complications such as central or foraminal stenosis. (orig.)

    2004-11-01

    We tried to assess the value of posterior epidural fat for distinguishing isthmic spondylolisthesis from degenerative lumbar spondylolisthesis on midline sagittal MR images. The midline sagittal MR images of the lumbar spines were retrospectively studied for 50 patients without spondylolisthesis, for 78 patients with isthmic spondylolisthesis and for 43 patients with degenerative spondylolisthesis. The anteroposterior diameter of the posterior epidural fat (ADEF) was measured at each intervertebral disc level by two radiologists and these values were then compared between each group. To normalize for difference of body size, the posterior epidural fat ratio (PEFR) at each level of spondylolisthesis and at L1-2 were also determined for each level of spondylolisthesis, and the PERF was compared between each group. Statistical analysis was performed by the chi-square method. For the patients with isthmic spondylolisthesis, the ADEFs at the spinal levels with spondylolisthesis were significantly greater than those ADEFs in the control group that were measured at the corresponding disc levels (p<0.05). For the patients with degenerative spondylolisthesis, the ADEFs at the spinal level with spondylolisthesis were significantly less than the ADEFs in the control group that were measured at the corresponding disc levels (p<0.05). The PEFRs obtained at L4-5 were 1.37{+-}0.12 for the control group, 2.61{+-}1.31 for the patients with isthmic spondylolisthesis, and 0.60{+-}0.05 for the patients with degenerative spondylolisthesis. The PEFRs obtained at L5-S1 were 2.25{+-}1.32 for the control group, 3.47{+-}1.69 for the patients with isthmic spondylolisthesis and 1.65{+-}0.18 for the patients with degenerative spondylolisthesis. At both levels, the PEFRs were greatest for the isthmic spondylolisthesis group and smallest for the degenerative spondylolisthesis group, and all the differences were statistically significant.

    Degenerative-inflammatory lumbar spinal pathology is one of the most common reasons why individuals seek medical care, and low back pain is the main symptom among those most commonly associated with this pathologic condition. Pain is commonly attributed to degenerative disc disease, particularly herniated discs, but many different spinal and perispinal structures may undergo degenerative-inflammatory phenomena and produce pain: discs, bone, facet joints, ligaments and muscles. In particular, in patients with non-radicular low back pain, this syndrome may arise from changes of the posterior elements/perispinal tissues of the lumbar spine (i.e., the ''posterior vertebral compartment''). They include: facet joint pathology (e.g., osteoarthritis, joint effusion, synovitis and synovial cysts), spondylolysis, spinal/perispinal ligamentous degenerative-inflammatory changes and perispinal muscular changes. It is well known that magnetic resonance is the most sensitive imaging method for the evaluation of spinal degenerative pathology, even in the initial stages of the disease. T2-weighted sequences with fat saturation, and when indicated the use of contrast-enhanced T1-weighted images with fat saturation, permit the visualization of degenerative-inflammatory changes of the posterior elements of the lumbar spine that in most cases would have been overlooked with conventional non-fat suppressed imaging.

    Full Text Available Nontraumatic anterior subluxation and dislocation of the hip joint are extremely rare. A 58-year-old woman presented to our outpatient clinic with left hip pain with a duration of 15 years. There was no history of trauma or other diseases. Her hip pain usually occurred only on walking and not at rest. Physical examinations demonstrated no tenderness in the hip joint. The range of motion of both hip joints was almost normal. Laxity of other joints was not observed. The bone mineral density of the lumbar spine and proximal femur confirmed a diagnosis of osteoporosis. A plain radiograph showed osteoarthritic changes of the hip joints, severe posterior pelvic tilt, and superior displacement of both femoral heads, especially in a standing position. Three-dimensional computed tomography (3DCT revealed anterior subluxation of both femoral heads. Seven years after the initial visit, both hip joints showed progression to severe osteoarthritis. Although the exact cause remains unclear, lumbar kyphosis, posterior pelvic tilt, and a decrease in acetabular coverage may have influenced the current case. We should be aware of these factors when we examine patients with hip osteoarthritis.

    The measure of radiographic pelvic and spinal parameters for sagittal balance analysis has gained importance in reconstructive surgery of the spine and particularly in degenerative spinal diseases (DSD). Fusion in the lumbar spine may result in loss of lumbar lordosis (LL), with possible compensatory mechanisms: decreased sacral slope (SS), increased pelvic tilt (PT) and decreased thoracic kyphosis (TK). An increase in PT after surgery is correlated with postoperative back pain. A decreased SS and/or abnormal sagittal vertical axis (SVA) after fusion have a higher risk of adjacent segment degeneration. High pelvic incidence (PI) increases the risk of sagittal imbalance after spine fusion and is a predictive factor for degenerative spondylolisthesis. Restoration of a normal PT after surgery is correlated with good clinical outcome. Therefore, there is a need for comparative prospective studies that include pre- and postoperative spinopelvic parameters and compare complication rate, degree of disability, pain and quality of life.

    Although the anatomy of the thoracic pedicle in adolescent idiopathic scoliosis is well known, that of the lumbar pedicle in degenerative lumbar scoliosis is not. The morphometric differences between the pedicles on the concave and convex sides can result in an increased risk of malpositioned pedicle screws. The purpose of this study was to analyze the lumbar pedicle morphology in degenerative lumbar scoliosis using multiplanar reconstructed CT. The study group comprised 16 consecutive patients (1 man and 15 women, mean age 70.9 ± 4.5 years) with degenerative lumbar scoliosis characterized by a Cobb angle of at least 30° who underwent preoperative helical CT scans. The CT data in DICOM format were reconstructed, and the following parameters were measured for each pedicle inside the curves: the inner cortical transverse pedicle width (TPWi) and outer cortical transverse pedicle width (TPWo) and axial angle, all on an axial plane, and the inner cortical minimum pedicle diameter (MPDi) and outer cortical minimum pedicle diameter (MPDo) and cephalocaudal inclination of the pedicle, all on the plane perpendicular to the pedicle axis. The cortical thickness and cortical ratio of the pedicles on the axial plane and the plane perpendicular to the pedicle axis were calculated. Data were obtained for a total of 124 pedicles; L-1, 26 pedicles in 13 patients; L-2, 32 pedicles in 16 patients; L-3, 32 pedicles in 16 patients; L-4, 28 pedicles in 14 patients; and L-5, 6 pedicles in 3 patients. Among the target vertebrae, the TPWi, MPDi, and MPDo were significantly smaller and the axial angle was significantly larger on the concave side than on the convex side (TPWi, 6.37 vs 6.70 mm, p < 0.01; MPDi, 5.15 vs 5.67 mm, p < 0.01; MPDo, 7.91 vs 8.37 mm, p < 0.05; axial angle, 11.79° vs 10.56°, p < 0.01). The cortical ratio of the pedicles was larger on the concave side than on the convex side (on the axial plane, 0.29 vs 0.26, p < 0.05; on the plane perpendicular to the pedicle

    To determine if cantilever transforaminal lumbar interbody fusion (C-TLIF) using the crescent-shaped titanium interbody spacer (IBS) favors acquisition of segmental and lumbar lordosis even for degenerative spondylolisthesis (DS) on a long-term basis. We analyzed 23 consecutive patients who underwent C-TLIF with pedicle screw instrumentations fixed with compression for a single-level DS. Measurements on the lateral radiographs taken preoperatively, 2 weeks postoperatively and at final follow-up included disc angle (DA), segmental angle (SA), lumbar lordosis (LL), disc height (%DH) and slip rate (%slip). There was a good functional recovery with 100 % fusion rate at the mean follow-up of 62 months. Segmental lordosis (DA and SA) and %DH initially increased, but subsequently decreased with the subsidence of the interbody spacer, resulting in a significant increase (p = 0.046) only in SA from 13.2° ± 5.5° preoperatively to 14.7° ± 6.4° at the final follow-up. Changes of LL and %slip were more consistent without correction loss finally showing an increase of LL by 3.6° (p = 0.005) and a slip reduction by 6.7 % (p lordosis on a long-term basis, which would be of benefit in preventing hypolordosis-induced back pain and the adjacent level disc disease.

    Intervertebral disc degeneration and facet joint osteoarthritis of the lumbar spine are, among others, wellknown as a cause of low back and lower extremity pain. Together with their secondary disorders they set a big burden on health care systems and economics worldwide. Despite modern imaging modalities, such as magnetic resonance imaging, for a large proportion of patients with low back pain(LBP) it remains difficult to provide a specific diagnosis. The fact that nearly all the lumbar structures are possible sources of LBP, may serve as a possible explanation. Furthermore, our clinical experience confirms, that imaging alone is not a sufficient approach explaining LBP. Here, the Oswestry Disability Index, as the most commonly used measure to quantify disability for LBP, may serve as an easy-toapply questionnaire to evaluate the patient’s ability to cope with everyday life. For therapeutic purposes, among the different options, the lumbar facet joint intraarticular injection of corticosteroids in combination with an anaesthetic solution is one of the most frequently performed interventional procedures. Although widely used the clinical benefit of intra-articular steroid injections remains controversial. Therefore, prior to therapy, standardized diagnostic algorithms for an accurate assessment, classification and correlation of degenerative changes of the lumbar spine are needed.

    Eight patients with parenchymatous cerebellar degeneration (PCD) group (3 with late cortical cerebellar atrophy and 5 with Holmes' hereditary ataxia), 14 with olivo-ponto-cerebellar atrophy (OPCA) group (4 with Shy-Drager syndrome, 6 with OPCA without family history and 4 with Menzel type SCS), 15 with Parkinson's disease and 44 control with other neurological diseases were studied. In all the spinocerebellar degenerative disorders (SCD) cases, CVI values corresponding to the cerebellar atrophy were definitely reduced. On the other hand, PVI values corresponding to the pontine atrophy were only significantly decreased in OPCA group. However, since there were several cases showing only questionable pontine atrophy, it seems difficult to clearly differentiate individual OPCA cases from other SCD cases on CT films alone. Concerning monoamine metabolites in CSF, it was noted that a significant reduction of HVA and total MHPG was found in the OPCA group. Among them, the patients with overt autonomic failure showed the lowest HVA level and the cases of Menzel type of SCD showed a slight reduction of HVA but an unexpected elevation of free MHPG values. The cases of Parkinson's disease showed a definite reduction of HVA. On the other hand, the cases of PCD group showed no significant difference against controls. 5-HIAA levels were not significantly different among the SCD subgroups.

    Directory of Open Access Journals (Sweden)

    Yin'gang Zhang, Zhengming Sun, Jiangtao Liu, Xiong Guo

    2008-01-01

    Full Text Available The traditional view that the etiology of lumbar disc herniation is primarily due to age, gender, occupation, smoking and exposure to vehicular vibration dominated much of the last century. Recent research indicates that heredity may be largely responsible for the degeneration as well as herniation of intervertebral discs. Since 1998, genetic influences have been confirmed by the identification of several genes forms associated with disc degeneration. These researches are paving the way for a better understanding of the biologic mechanisms. Now, many researchers unanimously agree that lumbar disc herniation appears to be similar to other complex diseases, whose etiology has both environmental and hereditary influence, each with a part of contribution and relative risk. Then addressing the etiological of lumbar disc herniation, it is important to integrate heredity with the environment factors. For the purpose of this review, we have limited our discussion to several susceptibility genes associated with disc degeneration.

  16. Inflammation and the degenerative diseases of aging.

    Science.gov (United States)

    McGeer, Patrick L; McGeer, Edith G

    2004-12-01

    Chronic inflammation is associated with a broad spectrum of neurodegenerative diseases of aging. Included are such disorders as Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis, the Parkinson-dementia complex of Guam, all of the tauopathies, and age-related macular degeneration. Also included are such peripheral conditions as osteoarthritis, rheumatoid arthritis, atherosclerosis, and myocardial infarction. Inflammation is a two-edged sword. In acute situations, or at low levels, it deals with the abnormality and promotes healing. When chronically sustained at high levels, it can seriously damage viable host tissue. We describe this latter phenomenon as autotoxicity to distinguish it from autoimmunity. The latter involves a lymphocyte-directed attack against self proteins. Autotoxicity, on the other hand, is determined by the concentration and degree of activation of tissue-based monocytic phagocytes. Microglial cells are the brain representatives of the monocyte phagocytic system. Biochemically, the intensity of their activation is related to a spectrum of inflammatory mediators generated by a variety of local cells. The known spectrum includes, but is not limited to, prostaglandins, pentraxins, complement components, anaphylotoxins, cytokines, chemokines, proteases, protease inhibitors, adhesion molecules, and free radicals. This spectrum offers a huge variety of targets for new anti-inflammatory agents. It has been suggested, largely on the basis of transgenic mouse models, that stimulating inflammation rather than inhibiting it can be beneficial in such diseases as AD. If this were the case, administration of NSAIDs, or other anti-inflammatory drugs, would be expected to exacerbate conditions such as AD, PD, and atherosclerosis. However, epidemiological evidence overwhelmingly demonstrates that the reverse is true. This indicates that, at least in these diseases, the inflammation is harmful. So far, advantage has not been taken

    Thanks to the development of several new researches, the lifetime presented a significant increase, even so, we still have many obstacles to overcome – among them, manage and get responses regarding neurodegenerative diseases. Where we are in the understanding of neuroprotection? Do we really have protective therapies for diseases considered degeneratives such as amyotrophic lateral sclerosis and its variants, Parkinson’s disease, Alzheimer’s disease and many others? Neuroprotection is defined by many researches as interactions and interventions that can slow down or even inhibit the progression of neuronal degeneration process. We make some considerations on this neuroprotective effect. PMID:27127599

  19. Vitiligo: a possible model of degenerative diseases.

    Directory of Open Access Journals (Sweden)

    Barbara Bellei

    Full Text Available Vitiligo is characterized by the progressive disappearance of pigment cells from skin and hair follicle. Several in vitro and in vivo studies show evidence of an altered redox status, suggesting that loss of cellular redox equilibrium might be the pathogenic mechanism in vitiligo. However, despite the numerous data supporting a pathogenic role of oxidative stress, there is still no consensus explanation underlying the oxidative stress-driven disappear of melanocytes from the epidermis. In this study, in vitro characterization of melanocytes cultures from non-lesional vitiligo skin revealed at the cellular level aberrant function of signal transduction pathways common with neurodegenerative diseases including modification of lipid metabolism, hyperactivation of mitogen-activated protein kinase (MAPK and cAMP response element-binding protein (CREB, constitutive p53-dependent stress signal transduction cascades, and enhanced sensibility to pro-apoptotic stimuli. Notably, these long-term effects of subcytotoxic oxidative stress are also biomarkers of pre-senescent cellular phenotype. Consistent with this, vitiligo cells showed a significant increase in p16 that did not correlate with the chronological age of the donor. Moreover, vitiligo melanocytes produced many biologically active proteins among the senescence-associated secretory phenotype (SAPS, such as interleukin-6 (IL-6, matrix metallo proteinase-3 (MMP3, cyclooxygenase-2 (Cox-2, insulin-like growth factor-binding protein-3 and 7 (IGFBP3, IGFBP7. Together, these data argue for a complicated pathophysiologic puzzle underlying melanocytes degeneration resembling, from the biological point of view, neurodegenerative diseases. Our results suggest new possible targets for intervention that in combination with current therapies could correct melanocytes intrinsic defects.

Consistent with this, vitiligo cells showed a significant increase in p16 that did not correlate with the chronological age of the donor. Moreover, vitiligo melanocytes produced many biologically active proteins among the senescence-associated secretory phenotype (SAPS), such as interleukin-6 (IL-6), matrix metallo proteinase-3 (MMP3), cyclooxygenase-2 (Cox-2), insulin-like growth factor-binding protein-3 and 7 (IGFBP3, IGFBP7). Together, these data argue for a complicated pathophysiologic puzzle underlying melanocytes degeneration resembling, from the biological point of view, neurodegenerative diseases. Our results suggest new possible targets for intervention that in combination with current therapies could correct melanocytes intrinsic defects. PMID:23555779

    Vitiligo is characterized by the progressive disappearance of pigment cells from skin and hair follicle. Several in vitro and in vivo studies show evidence of an altered redox status, suggesting that loss of cellular redox equilibrium might be the pathogenic mechanism in vitiligo. However, despite the numerous data supporting a pathogenic role of oxidative stress, there is still no consensus explanation underlying the oxidative stress-driven disappear of melanocytes from the epidermis. In this study, in vitro characterization of melanocytes cultures from non-lesional vitiligo skin revealed at the cellular level aberrant function of signal transduction pathways common with neurodegenerative diseases including modification of lipid metabolism, hyperactivation of mitogen-activated protein kinase (MAPK) and cAMP response element-binding protein (CREB), constitutive p53-dependent stress signal transduction cascades, and enhanced sensibility to pro-apoptotic stimuli. Notably, these long-term effects of subcytotoxic oxidative stress are also biomarkers of pre-senescent cellular phenotype.

    To compare MR myelography(MRM) using heavily T2 weighted fast spin echo(FSE) with conventional myelography in the evaluation of lumbar degenerative disc diseases. A total of 50 patients with lumbar degenerative disc diseases underwent both MRM and conventional myelography. A 1.5 T Sigma MR system was used. For MRM, heavily T2 weighted FSE pulse sequences were performed in sagittal, coronal and both oblique planes. The images of MRM and conventional myelography were analyzed retrospectively and compared, focusing on the pattern of compression of the cal sac and nerve roots. MRM yielded comparable images to conventional myelography in 68% (34/50). MRM was superior to conventional myelography in 11 cases (22%), and the opposite resulted in 5 cases(10%). MRM could visualize the spinal canal below the level of complete block in 6 patients, provided better contrast in the cases of dural ectasia in 3 cases and better delineation of individual nerve roots with source images in 1 case. Additional informations such as incidental retroperitoneal vascular malformation and extravasation of the CSF could be obtained by MRM in 1 case each. Disadvantages of MRM were poor contrast in the cases of multiple spinal stenosis, obscuration of the nerve roots by engorged paraspinal vessels, and occasional difficulty in defining the levels due to vanishment of the bony background image. MRM is a safe, noninvasive, nonionizing which in very effective in evaluating the lumbosacral disc disease. Use of FSE-MRM in addition to the routine MR imaging could be very helpful not only for better evaluation of nerve roots but also for the additional informations.

    Objective To summarize and evaluate the cause and preventions of peri-operational complications associ-ated with surgical treatment for lumbar degenerative diseases. Methods A total of 784 patients with degenerative diseases of lumbar spine undergoing posterior surgical treatment between October 2005 and October 2011 were analyzed retrospectively. Results 80 cases (10. 2%) experienced peri-operation complications in 784 patients. The most common complication was temporary postsurgical sciatica (4. 6%, 36 patients), which was relieved after symptomatic treatment. There were 31 patients (4. 0%) with cerebrospinal fluid leakage, of the 27 patients with dural tears during the operations, 24 had the tear repair im-mediately, and 3 were covered by adipose tissue. 4 patients had CSF leakage without obvious dural tears during the surgery. Wound drainage was kept for 12 days post surgery or less than 50 ml of 24-hour-drainage for the treatment of CSF leakage. There were 9 patients (1. 1%) with neurological deficit after operation, 7 patients recovered completely in 3 months post sur-gery. Only one had numbness of dorsal foot and one had foot drop. Deep wound infections occurred in 4 patients (0. 5%), 2 of these patients recovered after debridement and systemic antibiotics treatments without removal of spinal instrumentation. One patient died of secondary multiple organs failure after debridement and implants extraction. One patient was successfully trea-ted with systemic antibiotics therapy only. Conclusion Comprehensive knowledge anatomy of the lumbar spine, appropriate surgical technique and intense careful skills during operation are critical in preventing, detecting, and managing complications in low back surgeries.%目的:总结分析下腰椎退行性疾病后路手术相关早期并发症发生情况,探讨其发生原因及处理对策。方法回顾分析2005年10月—2011年10月我院采用后路手术治疗下腰椎退行性疾病784例的临床

    Idiopathic Parkinson's disease (PD) and Alzheimer's disease (AD) are the main neuro-degenerative diseases (NDDs) seen clinically. They share some common clinical symptoms and neuro-pathological findings. The increase of life expectancy in the developed countries will inevitably contribute to enhance the prevalence of these diseases. Behavioral disorders, common in NDDs, will produce major care management challenges. Idiopathic Parkinson's disease corresponds to a histopathological diagnosis, based on the observation of a de-pigmentation and a neuronal loss in the substantia nigra, as well as on the presence of intra-neuronal inclusion bodies. AD is insidious with slowly progressive dementia in which the decline in memory constitutes the main complaint. The diagnosis of definite AD requires the presence of clinical criteria as well as the histopathological confirmation of brain lesions. The two main lesions are the presence of senile plaques and neuro-fibrillary tangles. Positron emission tomography (PET) explores cerebral metabolism and neurotransmitter kinetics in NDDs using principally [{sup 18}F]-deoxyglucose and [{sup 18}F]-dopa. Nigrostriatal dopaminergic function is altered in PD, as evidenced by the low uptake of [{sup 18}F]-dopa in the posterior putamen as compared to anterior putamen and caudate nucleus. In contrast, [{sup 18}F]-dopa uptake is equally depressed in all striatal structures in progressive supra-nuclear palsy. Regional glucose metabolism at rest is preserved in elderly once cerebral atrophy is taken into account. On the contrary, glucose metabolism is globally reduced in AD, with marked decrease in the parietal and temporal regions. PET has proved to be useful to study in vivo neurochemical processes in patients suffering from NDDs. The potential of this approach is still largely unexploited, and depends on new ligand production to establish early diagnosis and treatment follow-up. (author)

    BACKGROUND CONTEXT. Proximal junctional kyphosis (PJK) following surgical treatment of lumbar degenerative kyphosis (LDK) is one of the critical complications leading to the failure of instrumentation and additional extensive surgery. However, most previous studies have focused on idiopathic scoliosis resulting from variable surgical techniques. LDK usually differ from other scoliotic deformities in terms of patient characteristics and disease mechanisms. PURPOSE. Identification of the prevalence of PJK after the surgical treatment of LDK and searching for the predictable value for the progression of PJK. Study design. Retrospective comparative study. Patient sample (must be included in clinical studies). Forty-seven consecutive patients who underwent surgical correction of a sagittal imbalance due to LDK, from January 2005 to December 2008 in a single spine clinic, were evaluated with a minimum 2 years follow-up (mean 3.8 years). METHODS. Patients were divided into 2 groups: with or without the occurrence of PJK, and three categorized factors according to patient characteristics, surgical variables, and the radiographic spinopelvic parameters were evaluated. RESULTS. PJK had occurred in 29 of 47 patients (61.7%). Among variable factors, old age, upper-instrumented vertebra below L2, lumbar lordosis to PI ratio, and the sum of lumbar lordosis, and the sacral slope related to PI were found to be statistically significant. CONCLUSIONS. The overall incidence of PJK following surgical treatment of LDK patients was higher than expected. Spinal biomechanics may be changed after long instrumented fusion surgery. Thorough consideration of these factors is needed in the treatment strategy of LDK patients. A long-term follow-up study should be conducted.

    Introduction Degenerative lumbar spinal stenosis (DLSS) is a major public health problem and the primary reason why older adults seek lumbar spine surgery. Acupuncture may be effective for DLSS, but the evidence supporting this possibility is still limited. Methods and analysis A total of 80 participants with DLSS will be randomly allocated to either an acupuncture group or a sham acupuncture (SA) group at a ratio of 1:1. 24 treatments will be provided over 8 weeks. The primary outcome is the score change of the Modified Roland-Morris Disability Questionnaire (RMDQ) responses from baseline to week 8. The secondary outcomes include the assessment of lower back pain and leg pain using the Numeric Rating Scale (NRS), the change in the number of steps per month, and the assessment of the specific quality of life using the Swiss Spinal Stenosis Questionnaire (SSSQ). We will follow-up with the participants until week 32. All of the participants who received allocation will be included in the statistical analysis. Ethics/dissemination This protocol has been approved by the Research Ethical Committee of Guang'anmen Hospital (Permission number: 2015EC114) and Fengtai Hospital of Integrated Traditional and Western Medicine (Permission number: 16KE0409). The full data set will be made available when this trial is completed and published. Applications for the release of data should be made to ZL (principal investigator).

    The high energy (1-4MeV) focused ion beam (nuclear microbeam) has found uses in many scientific disciplines through a wide variety of ion beam based techniques. Of the many techniques available, the powerful combination of Particle Induced X-Ray Emission (PIXE), Rutherford Backscattering Spectrometry (RBS), and Scanning Transmission Ion Microscopy (STIM) is proving to be extremely useful, particularly in the characterisation and elemental analysis of thin specimens. In this paper we briefly review these ion beam techniques, as well as the hardware required for their application. Finally, we describe the application of the PIXE, RBS and STIM techniques in conjunction with a scanning focused 2MeV proton microbeam (nuclear microscopy). The examples chosen to illustrate the potential of nuclear microscopy are recent investigations into the degenerative diseases atherosclerosis (coronary heart disease), Parkinson`s disease and Alzheimer`s disease.

    Full Text Available OBJECTIVE: Perform radiographic analysis of the use of Transverse Traction Device (DTT with respect to fusion rate in patients submitted to vertebral arthrodesis for degenerative lumbar diseases. METHODS: We selected x-ray images on anteroposterior, lateral and oblique views and with maximum flexion and extension dynamics of 23 patients submitted to posterolateral arthrodesis of the lumbar spine with a minimum follow-up period of six months. The images were evaluated and classified by the Linovitz's system by two spine surgeons. RESULTS: We evaluated the radiographs of 23 patients after the minimum postoperative period of 6 months and of these, 11 have used DTT. With regard to the consolidation rate, seven patients (63.6% in the group of DTT were classified as fusion as well as six patients (50% who were not submitted to the treatment. There was no statistical difference between the groups regarding the consolidation rate. CONCLUSION: The use of transverse traction device in this study showed no significant difference in the rate of consolidation in radiographic evaluation. Studies on the effective participation of this device in the stability of pedicle fixation systems are still lacking in the literature.

    Full Text Available Background: Recent studies have indicated the relation of vertebral endplate lesions (Modic changes to low back pain (LBP. The aim of this study was to investigate the Modic changes in magnetic resonance imaging (MRI of patients with low back pain, and its correlation with age, sex, type of changes, number of involved segments and location of changes. Additionally, association of degenerative disc changes and disc herniation was assessed. Methods: In this retrospective study, MRI records of 229 patients with LBP referring to Medical Center of Hazrat-e-Rasoul Hospital, Tehran, Iran, from August to February 2014, were assessed and Modic changes and degenerative and herniated disc changes were recorded. Results: Based on our observations, a significant association between Modic type and age (P= 0.003 existed in patients with LBP. The highest prevalence in Modic location were observed in anterior part of vertebral endplate (48.8%, P= 0.001. Although, observation of the Modic changes in superior vertebral endplate was higher than inferior parts, but this differences was not statistically significant. The highest prevalence in degenerative disc disease was disc dehydration which was observed in 18.1% of patients (P= 0.04. The relationship between the degenerative changes and Modic type was significant (P= 0.04, while the most prevalent change of disc contour was disc bulging which occurred in 23.7% of patients (P= 0.01. The highest frequency of abnormal disc contour were observed in Modic type 2 which was statistically significant (P= 0.01. Modic surface involvement above 25% was significantly associated with disc herniation (P= 0.04. There was no significant association between Modic height involvement above 25% and disc herniation. Conclusion: Considering significant association between Modic changes and degenerative and herniated disc changes, reporting of Modic changes is necessary.

  16. Long term results of radiotherapy of degenerative joint diseases

    1982-04-01

    At the Radiologic Department of the Staedt. Krankenhaus Passau, 473 patients with degenerative diseases in the big joints and the spine were irradiated with the caesium unit between 1971 and 1979. Among these patients, 249 could be followed up during a prolonged period (1/2 to 9 years, i.e. 4.2 years on an average). According to the categories of v. Pannewitz, 11% were pain-free at this moment, 21% showed an essential improvement, 29% showed an improvement, and 39% were not influenced by the treatment. 13.5% showed recurrent pains; these were mentioned as 'not influenced' in the statistical analysis. It is proved that the relief of pain does not depend on the age of the patients, but on the anamnesis period, the results of the X-ray examiantion, and the degree of the restriction of mobility. Due to the delay of irradiation, a preliminary treatment mostly produces a less favorable radiotherapeutic result. Compared with other therapeutic methods, the long term results of radiotherapy of degenerative joint diseases are generally favorable. This conclusion is also confirmed by the results of patients checked up more than five years after the treatment.

    The paper presents a clinical and neurological analysis of 110 patients with discal hernias who were divided into 2 groups: 1) 50 patients with normal sizes of the vertebral column; 2) 51 patients with its stenosis. Compression syndromes were major in all cases. In patients in whom discal hernia was concurrent with lumbar stenosis, the clinical course was characterized by dull or aching pains in the low back and legs, by symptoms of dysbasia neurasthenica intermittens, severe motor and sensory disorders with autonomic impositions.

    Conclusions: The post-operative VAS, ODI, JOA, SF-36 scores showed a significant improvement from the preoperative ones. Postoperative thecal sac measurements showed a significant neural decompression substantiating the results of improvement in the functional assessment scores after surgery. The treadmill test is a quantifiable means of dynamic function. It may be considered as a useful tool for the assessment of functional impairment and for the correlation of thecal sac CSA with lumbar canal stenosis. A combination of functional scores, treadmill test, and thecal sac CSA may be included in the preoperative assessment of outcome in patients with LCS.

    The complement system is a key innate immune defence against infection and an important driver of inflammation; however, these very properties can also cause harm. Inappropriate or uncontrolled activation of complement can cause local and/or systemic inflammation, tissue damage and disease. Complement provides numerous options for drug development as it is a proteolytic cascade that involves nine specific proteases, unique multimolecular activation and lytic complexes, an arsenal of natural inhibitors, and numerous receptors that bind to activation fragments. Drug design is facilitated by the increasingly detailed structural understanding of the molecules involved in the complement system. Only two anti-complement drugs are currently on the market, but many more are being developed for diseases that include infectious, inflammatory, degenerative, traumatic and neoplastic disorders. In this Review, we describe the history, current landscape and future directions for anti-complement therapies.

    A literature review. The purpose of this study was to review lumbar segmental and regional alignment changes following treatment with a variety of minimally invasive surgery (MIS) interbody fusion procedures for short-segment, degenerative conditions. An increasing number of lumbar fusions are being performed with minimally invasive exposures, despite a perception that minimally invasive lumbar interbody fusion procedures are unable to affect segmental and regional lordosis. Through a MEDLINE and Google Scholar search, a total of 23 articles were identified that reported alignment following minimally invasive lumbar fusion for degenerative (nondeformity) lumbar spinal conditions to examine aggregate changes in postoperative alignment. Of the 23 studies identified, 28 study cohorts were included in the analysis. Procedural cohorts included MIS ALIF (two), extreme lateral interbody fusion (XLIF) (16), and MIS posterior/transforaminal lumbar interbody fusion (P/TLIF) (11). Across 19 study cohorts and 720 patients, weighted average of lumbar lordosis preoperatively for all procedures was 43.5° (range 28.4°-52.5°) and increased 3.4° (9%) (range -2° to 7.4°) postoperatively (P lordosis increased, on average, by 4° from a weighted average of 8.3° preoperatively (range -0.8° to 15.8°) to 11.2° at postoperative time points (range -0.2° to 22.8°) (P lordosis and change in lumbar lordosis (r = 0.413; P = 0.003), wherein lower preoperative lumbar lordosis predicted a greater increase in postoperative lumbar lordosis. Significant gains in both weighted average lumbar lordosis and segmental lordosis were seen following MIS interbody fusion. None of the segmental lordosis cohorts and only two of the 19 lumbar lordosis cohorts showed decreases in lordosis postoperatively. These results suggest that MIS approaches are able to impact regional and local segmental alignment and that preoperative patient factors can impact the extent of correction gained

Background: Different methods are available for treating lumbar spinal canal stenosis (LSCS. A minimally invasive surgery, namely, space shuttle laminotomy, has recently been proposed. Here, we describe the surgical method for this novel technique. To conduct this surgery accurately, surgeons must have perfect knowledge of anatomy, especially regarding the LF. Materials and Methods and Results: We use this interlaminectomy technique for all cases of LSCS. All patients with LSCS recovered from their neurological deficits in shorter hoslital stays than regular laminectomy. Conclusion: Minimally invasive space shuttle laminotomy (MISSL, which involves a microsurgical technique, is a safe, complication-free procedure.

  9. Vitamin K, osteoporosis and degenerative diseases of ageing.

    2011-03-01

    The function of vitamin K is to serve as a co-factor during the post-translational carboxylation of glutamate (Glu) residues into γ-carboxyglutamate (Gla) residues. The vital importance of the Gla-proteins essential for normal haemostasis is well recognized. During recent years, new Gla-containing proteins have been discovered and the vitamin K-dependent carboxylation is also essential for their function. It seems, however, that our dietary vitamin K intake is too low to support the carboxylation of at least some of these Gla-proteins. According to the triage theory, long-term vitamin K inadequacy is an independent, but modifiable risk factor for the development of degenerative diseases of ageing including osteoporosis and atherosclerosis.

    Stem cell-derived retinal pigment epithelium (RPE) and photoreceptors (PRs) have restored vision in preclinical models of human retinal degenerative disease. This review discusses characteristics of stem cell therapy in the eye and the challenges to clinical implementation that are being confronted today. Based on encouraging results from Phase I/II trials, the first Phase II clinical trials of stem cell-derived RPE transplantation are underway. PR transplant experiments have demonstrated restoration of visual function in preclinical models of retinitis pigmentosa and macular degeneration, but also indicate that no single approach is likely to succeed in overcoming PR loss in all cases. A greater understanding of the mechanisms controlling synapse formation as well as the immunoreactivity of transplanted retinal cells is urgently needed.

    The therapeutic effect of Tuina combined with core stability exercises on low back pain resulted from lumbar degenerative instability is unclear. This article aims to evaluate whether core stability exercises can improve the effect of Tuina in this regard. This trial was designed as a randomized controlled trial and carried out in Qingzhou hospital of Traditional Chinese medicine between June 2011 and June 2013. Eighty-eight patients with low-grade lumbar degenerative instability were included and divided randomly into experimental and control groups, 44 in each. The experimental group were treated using Tuina combined with core stability exercises, but the control group using Tuina alone. The evaluation of Visual analogue scale (VAS), Japanese Orthopaedic Association scores (JOA) and recurrence rate were performed. Two weeks after treatment, JOA scores increased (p0.05) between the two groups. At the end of six weeks, VAS scores (pcore stability exercises has better effect than Tuina alone in treating low back pain resulted from low-grade lumbar degenerative instability.

    In order to evaluate the diagnostic efficacy of pinhole collimator (PHC) imaging combined with an X-ray for vertebral metastasis, our prospective study has employed receiver operating characteristics (ROC) analysis in 21 patients, 11 with osseous metastasis and 15 with degenerative joint disease in the lumbar vertebrae. PHC imaging provided better anatomic information on the extent of {sup 99m}Tc-MDP accumulation. PHC vertebral scintigraphy had a considerable impact on the decision-making process, although with variations and not very satisfactory results among the physicians with little experience. Our study suggests that PHC imaging and X-ray film are useful in differentiating between osseous metastasis and degenerative joint disease in the vertebra. (author).

    Physical therapy is commonly prescribed for patients with lumbar spinal stenosis (LSS); however, little is known about its effectiveness. The purpose of this study was to systematically review randomized controlled trials (RCTs), controlled trials, and cohort studies evaluating the effectiveness of physical therapy for LSS. Studies were searched on electronic databases to January 2012. Inclusion criteria were: clinical diagnosis of LSS with confirmatory imaging, evaluation of physical therapy treatment, presence of a comparison group, and outcomes of pain, disability, function, or quality of life. Outcomes were extracted and, when possible, pooled using RevMan 5, a freely available review program from the Cochrane Library. Ten studies were included: 5 RCTs, 2 controlled trials, 2 mixed-design studies, and 1 longitudinal cohort study. Pooled effects of 2 studies revealed that the addition of a physical therapy modality to exercise had no statistically significant effect on outcome. Pooled effects results of RCTs evaluating surgery versus physical therapy demonstrated that surgery was better than physical therapy for pain and disability at long term (2 years) only. Other results suggested that exercise is significantly better than no exercise, that cycling and body-weight-supported treadmill walking have similar effects, and that corsets are better than no corsets. The limitations of this review include the low quality and small number of studies, as well as the heterogeneity in outcomes and treatments. No conclusions could be drawn from the review regarding which physical therapy treatment is superior for LSS. There was low-quality evidence suggesting that modalities have no additional effect to exercise and that surgery leads to better long-term (2 years) outcomes for pain and disability, but not walking distance, than physical therapy in patients with LSS.

    OBJECTIVE The development of symptomatic adjacent-segment disease (ASD) is a well-recognized consequence of lumbar fusion surgery. Extension of a fusion to a diseased segment may only lead to subsequent adjacent-segment degeneration. The authors report the use of a novel technique that uses dynamic stabilization instead of arthrodesis for the surgical treatment of symptomatic ASD following a prior lumbar instrumented fusion. METHODS A cohort of 28 consecutive patients was evaluated who developed symptomatic stenosis immediately adjacent to a previous lumbar instrumented fusion. All patients had symptoms of neurogenic claudication refractory to nonsurgical treatment and were surgically treated with decompression and dynamic stabilization instead of extending the fusion construct using a posterior lumbar dynamic stabilization system. Preoperative symptoms, visual analog scale (VAS) pain scores, and perioperative complications were recorded. Clinical outcome was gauged by comparing VAS scores prior to surgery and at the time of last follow-up. RESULTS The mean follow-up duration was 52 months (range 17-94 months). The mean interval from the time of primary fusion surgery to the dynamic stabilization surgery was 40 months (range 10-96 months). The mean patient age was 51 years (range 29-76 years). There were 19 (68%) men and 9 (32%) women. Twenty-three patients (82%) presented with low-back pain at time of surgery, whereas 24 patients (86%) presented with lower-extremity symptoms only. Twenty-four patients (86%) underwent operations that were performed using single-level dynamic stabilization, 3 patients (11%) were treated at 2 levels, and 1 patient underwent 3-level decompression and dynamic stabilization. The most commonly affected and treated level (46%) was L3-4. The mean preoperative VAS pain score was 8, whereas the mean postoperative score was 3. No patient required surgery for symptomatic degeneration rostral to the level of dynamic stabilization during the

    The measurement of transverse pedicle width is still recommended for selecting a screw diameter despite being weakly correlated with the minimum pedicle diameter, except in the upper lumbar spine. The purpose of this study was to reveal the difference between the minimum pedicle diameter and conventional transverse or sagittal pedicle width in degenerative lumbar spines. A total of 50 patients with degenerative lumbar disorders without spondylolysis or lumbar scoliosis of >10° who preoperatively underwent helical CT scans were included. The DICOM data of the scans were reconstructed by imaging software, and the transverse pedicle width (TPW), sagittal pedicle width (SPW), minimum pedicle diameter (MPD), and the cephalocaudal inclination of the pedicles were measured. The mean TPW/SPW/MPD values were 5.46/11.89/5.09 mm at L1, 5.76/10.44/5.39 mm at L2, 7.25/10.23/6.52 mm at L3, 9.01/9.36/6.83 mm at L4, and 12.86/8.95/7.36 mm at L5. There were significant differences between the TPW and MPD at L3, L4, and L5 (p < 0.01) and between the SPW and MPD at all levels (p < 0.01). The MPD was significantly smaller than the TPW and SPW at L3, L4, and L5. The actual measurements of the TPW were not appropriate for use as a direct index for the optimal pedicle screw diameter at these levels. Surgeons should be careful in determining pedicle screw diameter based on plain CT scans especially in the lower lumbar spine.

    Degenerative disc disease (DDD) develops in the spine as vertebral discs degenerate and osseous excrescences or outgrowths naturally form to restabilize unstable segments of the spine. These osseous excrescences, or osteophytes, may progress or stabilize in size as the spine reaches a new equilibrium point. We have previously created a CAD system that detects DDD. This paper presents a new system to determine the severity of DDD of individual vertebral levels. This will be useful to monitor the progress of developing DDD, as rapid growth may indicate that there is a greater stabilization problem that should be addressed. The existing DDD CAD system extracts the spine from CT images and segments the cortical shell of individual levels with a dual-surface model. The cortical shell is unwrapped, and is analyzed to detect the hyperdense regions of DDD. Three radiologists scored the severity of DDD of each disc space of 46 CT scans. Radiologists' scores and features generated from CAD detections were used to train a random forest classifier. The classifier then assessed the severity of DDD at each vertebral disc level. The agreement between the computer severity score and the average radiologist's score had a quadratic weighted Cohen's kappa of 0.64.

    Objective: To evaluate the influence of PI-LL (pelvic incidence minus lumbar lordosis mismatch) on scoliosis correction, living quality and internal fixation related complications for adult degenerative scoliosis (ASD) after long posterior instrumentation and fusion. Methods: A total of 79 patients with ADS underwent long posterior instrumentation and fusion in the Department of Orthopedics at Beijing Chao Yang Hospital from January 2010 to January 2014 were retrospectively reviewed.There were 21 males and 58 females aging from 55 to 72 years with the mean age (63.4±4.8)years. The patients were divided into three groups according to immediately postoperative PI-LL: PI-LL20°.Compare the Cobb's angles, PI-LL, Japanese Orthopaedic Association (JOA) score, Oswestry Disability Index (ODI), Visual Analog Scale (VAS) and Lumbar Stiffness Disability Index (LSDI). Measurement data were compared via t test and ANOVA, enumeration data were compared via Kruskal-Wallis test, noncontiguous data was performed by χ(2) test. Univariate linear regression equation was performed to investigate the relative influences of postoperative PI-LL on postoperative radiographic parameters and clinical outcome. Results: All the operations were successful without intraoperative complications.

    Full Text Available Among the various components of the diet, fat receives very dose attention because of its relationship to several chronic degenerative diseases (CDD. Currently most of the available information on these relationships is derived from epidemiologic or experimental studies in which lipid intake is calculated using food composition tables. In most of these tables the quoted lipid content is that of raw food, whereas most foods are usually consumed only after being subjected to several culinary processes. Often there is no indication of the type of fat used in food processing in general or in frying in particular. But as it known, in the course of these processes the lipid content undergoes important qualitative and quantitative changes and not keeping them in mind may be the underlying cause of the difficulties an the confounding results in studies trying to establish the relationship between lipid intake an health. In the Mediterranean diet, about 50% of total dietary fat is derived not from the food itself but from the cooking fat, of which only a small fraction is eaten raw (as dressings and the greatest proportion is used in thermal culinary processes, mainly deep-frying. The scientific study of the process whereby fat penetrates into fried foods has shown the benefits of this cooking method. If the process is correctly carried out, the amount of fat ingested with fried foodstuffs is not greater than when other procedures involving fat are used (for example, sautening, stewing or canning in oil. Very schematically deep-frying is a technique that replaces a fraction of the water content of food by cooking fat. Consecuently, the fat composition of the fried lean foods will be the same as that cooking fat. The process is more complex with fatty foods, and there are not great changes in the total quantity of fat in the fried food before and after frying. However, there are notable quality changes and these depend on the concentration gradients

    Concerning the Modic change of lumbar spinal endplate, the Modic change types, forming causes, and the relationship between Modic change and degenerative lumbar diseases have been studied from anatomy, pathology, molecular biology and many other aspects at present. The degeneration of lumbar disc is a high risk factor of the Modic change. The degeneration of lumbar disc usually starts from cartilage endplate degeneration. The injury of cartilage endplate could accelerate the degeneration of lumbar disc. This article reviews the significance of Modic change of lumbar spinal endplate in lumbar disc degeneration. The cause of Modic change of the endplate, pathological change, the influence of inflammatory mediators on the endplate and the significance of Modic change in the treatment of degenerative lumbar diseases are summarized to analyze the relationship between the degeneration of lumbar disc and Modic change of endplate and to describe the influence of Modic change in the treatment of degenerative lumbar disc diseases.

    Long-standing scaphoid nonunion, scaphoid malunion, and chronic scapholunate dissociation result in malalignment of the carpal bones, progressive carpal collapse, instability, and osteoarthritis of the wrist. The most commonly used procedures to treat scaphoid nonunion advanced collapse (SNAC) and scapholunate advanced collapse (SLAC) wrists are the four-corner fusion (4CF) and the proximal row carpectomy (PRC). The purpose of this study was to evaluate the clinical outcome of a different treatment modality: radial styloidectomy and scaphocapitolunate (SCL) arthrodesis. This treatment option is chosen in an effort to maintain the joint contact surface and load transmission across the radiocarpal joint. We conducted a retrospective review of 20 patients (average age 62 years, range: 27 to 75 years) treated from 1994 to 2010. Seven patients were treated for SNAC, 12 patients for SLAC wrists, and 1 for degenerative joint disease following a transscapho-transcapitate perilunar dislocation. Sixteen patients had Herbert screw fixation, and four had Spider plate fixation. All patients had autologous bone graft used for the arthrodesis. The mean follow-up was 4.6 years (range: 2 to 9.6 years). Patients were evaluated clinically and radiographically. Nineteen of 20 arthrodeses healed on an average of 9.6 weeks. One patient was reoperated 8 months after the initial operation with salvage of the SCL arthrodesis with a spider plate with an adequate result. The mean active flexion-extension arc was 70 degrees and the radioulnar deviation arc was 23 degrees. Pain decreased in all patients, 13 of whom were pain free postoperatively. The average postoperative disabilities of arm, shoulder, and hand score was 24. Radiographically, neither radiolunate nor radioscaphoid arthritis was noted on follow-up. SCL arthrodesis with radial styloidectomy resulted in an adequate residual range of motion and pain relief. This method preserves the normal ulnar sided joints of the carpus and

    Since the 1950s a causal relation between water hardness and cardiovascular diseases (CVD) in humans has been hypothesized. In order to evaluate the influence of calcium and magnesium, the minerals responsible for the hardness of drinking water, on human health, a review of all the articles published on the subject from 1980 up to today has been carried out. Many but not all geographic correlation studies showed an inverse association between water hardness and mortality for CVD. Most case-control and one cohort studies showed an inverse relation, statistically significant, between mortality from CVD and water levels of magnesium, but not calcium. Consumption of water containing high concentrations of magnesium seems to reduce of about 30-35% the mortality for CVD, but not the incidence. This inverse association is supported by clinical and experimental findings and is biologically plausible and in line with Hill's criteria for a cause-effect relationship.

    BACKGROUND:With the aging population, the incidence of lumbar degenerative disease was apparently increased, but how to treatment of degenerative lumbar disease remains controversial. OBJECTIVE:To compare clinical and radiographic results of minimaly invasive posterior lumbar interbody fusion and open posterior lumbar interbody fusion for single-segment degenerative lumbar disease. METHODS: We retrospectively analyzed the clinical data of 97 patients with single-segment degenerative lumbar disease, who were treated in the Huishan District People’s Hospital of Wuxi City from July 2006 to July 2012. These patients were divided into minimal group (minimaly invasive posterior lumbar interbody fusion;n=51) and open group (open posterior lumbar interbody fusion;n=46). These data were compared between the two groups, including operative time, blood loss (intraoperative blood volume+postoperative drainage volume), total blood transfusion, postoperative back pain (visual analogue scale), length of hospital stay, bed time, perioperative complications, clinical function (Oswestry disability index), and radiographic results. RESULTS AND CONCLUSION:Al of 97 patients were folowed up. The duration of folow-up was 28-78 months and 27-76 months in minimal group and open group, respectively. There was no significant difference between the minimal group and open group in term of folowed-up time (P=0.981). Operative time, blood loss, total blood transfusion, bed time, length of hospital stay and visual analogue scale score during final folow-up were significantly lower in the minimal group than in the open group (P 0.05). These results indicate that for the single-segment degenerative lumbar disease, the use of minimaly invasive posterior lumbar interbody fusion or open posterior lumbar interbody fusion can obtain satisfactory clinical function, but the minimaly invasive posterior lumbar interbody fusion has the advantages of a less trauma, shorter length of hospital stay and bed

    Retinal degenerative diseases, including age-related macular degeneration and retinitis pigmentosa, are the prodominant causes of human blindness in the world; however, these diseases are difficult to treat. Currently, knowledge on the mechanisms of these diseases is still very limited and no radical drugs are available. Induced pluripotent stem (iPS) cells are an innovative technology that turns somatic cells into embryonic stem (ES)-like cells with pluripotent potential via the exogenous expression of several key genes. It can be used as an unlimited source for cell differentiation or tissue engineering, either of which is a promising therapy for human degenerative diseases. Induced pluripotent cells are both an unlimited source for retinal regeneration and an expectant tool for pharmaprojects and developmental or disease modelling. In this review, we try to summarize the advancement of iPS-based technologies and the potential utility for retinal degenerative diseases. We also discuss the challenges of using this technology in the retinology field.

    Morphometric data were obtained from fresh cadaver dissections, and observations of degenerative changes in the joint cartilage (DCs) were analyzed to determine whether the morphometric parameters of the lumbar zygapophyseal joint capsule varied according to the presence and severity of DCs. There have been no previous morphometric studies of the facet capsule that describe age-related DCs. Using 23 fresh osteoligamentous lumbar spines from donated cadavers, we performed morphometric investigations of the surface areas of the joints and their capsules and measured the capsular thickness. We hypothesized that the ratio of the inner capsular area to the joint surface area for each facet (the capsule/facet index) could serve as an index showing a functional aspect of a large or small capsule. Our results showed that the joint surface area increased significantly with increasing severity of DCs, according to Grogan's classification. Facets with advanced DCs tended to have a small inner capsular surface. The capsule/facet index generally correlated positively with capsular thickness, especially the dorsal portion; however, this was not true for the ventral portion. The index also correlated negatively with DC progression. Thus, lumbar facet DCs were strongly linked to reconstructive alterations in capsular size, thickness, and looseness. The occurrence and progression of DCs narrowed the joint capsule, especially the dorsal portion, and this seemed to decrease the potential looseness of the joint. Conversely, these capsular alterations seemed to accelerate DC progression. A negative adaptation cycle seemed to occur.

    Full Text Available Abstract Background Available information suggests a mismatch between radiographic and orthopedic examination findings in cats with DJD. However, the extent of the discrepancy between clinical and radiographic signs of OA in companion animals has not been described in detail. This study aimed to evaluate the relationship between orthopedic examination findings, joint goniometry, and radiographic signs of DJD in 100 cats, in a prospective observational design. Cat temperament, pain response to palpation, joint crepitus, effusion and thickening were graded. Radiographs of appendicular joints and the axial skeleton were made under sedation. Joint motion was measured by use of a plastic goniometer before and after sedation. Associations between radiographic degenerative joint disease (DJD and examination findings were assessed to determine sensitivity, specificity and likelihood estimations. Results Pain response to palpation was elicited in 0-67% of the joints with DJD, with a specificity ranging from 62-99%; crepitus was detected in 0-56% of the joints and its specificity varied between 87 and 99%; for effusion, values ranged between 6 and 38% (specificity, 82-100%, and thickening, 0-59% (specificity, 74-99%. Joints with DJD tended to have a decreased range of motion. The presence of pain increased the odds of having DJD in the elbow (right: 5.5; left: 4.5; the presence of pain in the lower back increased the odds of spinal DJD being present (2.97 for lumbar; 4.67 for lumbo-sacral. Conclusions Radiographic DJD cannot be diagnosed with certainty using palpation or goniometry. However, negative findings tend to predict radiographically normal joints. Palpation and goniometry may be used as a tool to help to screen cats, mostly to rule out DJD.

    BACKGROUND:Osteoporosis is characterized as bone microstructure damage of the whole body and systemic osteopenia. Some scholars believe that the anterior vertebral height of patients with osteoporosis cannot decrease, but shows a trend of increase. OBJECTIVE: To investigate the correlation between degenerative lumbar scoliosis and osteoporosis. METHODS:Thirty-seven patients with degenerative lumbar scoliosis were selected as observation group and another 37 inpatients with no lumbar scoliosis as control group. Modified Cobb method was used to detect the maximum angle between paralel lines to the endplate on the T12-L5 vertebrae, and the vertebrae with these two paralel lines were regarded as upper and lower vertebrae. Dual energy X-ray absorptiometry was used to measure the bone mineral density of L2-L4 segments, femoral neck, Ward's triangle and femoral trochanter. Linear regression analysis was used to analyze the correlation between osteoporosis and degenerative lumbar scoliosis. RESULTS AND CONCLUSION:There were significant differences in the T values in the L2-L4 segments, femoral neck, Ward's triangle and femoral trochanter between the observation and control groups (P < 0.05), and the bone density of the femoral parts was lower than that of the lumbar vertebrae (L2-L4). The incidence of osteoporosis in the patients with lumbar scoliosis was significantly higher than that in the patients with no lumbar scoliosis (P < 0.05). Osteoporosis was a risk factor for degenerative lumbar scoliosis, and the T values of the lumbar vertebra and proximal femur had no remarkable correlation with Cobb's angles. These findings indicate that osteoporosis is the risk factor for degenerative lumbar scoliosis, but it has no correlation with the severity of scoliosis.%背景:骨质疏松是以全身骨组织显微结构损坏及全身骨量减少为特征,有学者认为骨质疏松患者腰椎椎体前高不会减少,反而会有增加的趋势.目的:分析退行性腰椎侧凸

    2015-09-01

    Lumbar degenerative disc disease without disc herniation, also known as discogenic pain, is an elusive diagnosis of chronic low back pain. Lumbar provocation discography and fusion surgery have been frequently utilized for several decades as the gold standards for the diagnosis and treatment of symptomatic lumbar discogenic pain, though controversial, based on conjecture, rather than evidence. In addition to lumbar fusion, various other operative and nonoperative modalities of treatments are available in managing chronic lumbar discogenic pain. This review provides an updated assessment of the management of chronic lumbar discogenic pain with a critical look at the many modalities of treatments that are currently available.

    The surgical repair of degenerative mitral valve disease involves a number of technical points of importance. The use of artificial chordae for the repair of degenerative disease has increased as a part of the move from mitral valve replacement to repair of the mitral valve. The use of artificial chordae provides an alternative to the techniques pioneered by Carpentier (including the quadrangular resection, transfer of native chordae and papillary muscle shortening/plasty), which can be more technically difficult. Despite a growth in their uptake and the indications for their use, a number of challenges remain for the use of artificial chordae in mitral valve repair, particularly in the determination of the correct length to ensure optimal leaflet coaptation. Here, we analyse over 40 techniques described for artificial chordae mitral valve repair in the setting of degenerative disease. PMID:22962321

    Full Text Available Osteoporosis has become a major medical problem as the aged population of the world rapidly grows. Osteoporosispredisposes patients to fracture, progressive spinal deformities, and stenosis, and is subject to be a major concernbefore performing spine surgery, especially with bone fusions and instrumentation. Osteoporosis has often beenconsidered a contraindication for spinal surgery, while in some instances patients have undergone limited and inadequateprocedures in order to avoid concomitant instrumentation. As the population ages and the expectations of older patientsincrease, the demand for surgical treatment in older patients with osteoporosis and spinal degenerative diseasesbecomes progressively more important. Nowadays, advances in surgical and anesthetic technology make it possible tooperate successfully on elderly patients who no longer accept disabling physical conditions. This article discusses thebiomechanics of the osteoporotic spine, the diagnosis and management of osteoporotic patients with spinal conditions,as well as the novel treatments, recommendations, surgical indications, strategies and instrumentation in patients withosteoporosis who need spine operations.

    This study prospectively examined the relationship of direct and indirect measures of shoulder activity with the risks of tear progression and pain development in subjects with an asymptomatic degenerative rotator cuff tear. A cohort of asymptomatic degenerative rotator cuff tears was prospectively monitored annually, documenting tear size progression with ultrasound imaging and potential shoulder pain development. Shoulder activity level, self-reported occupational and physical demand level, and hand dominance were compared with risks of tear enlargement and future pain development. The study monitored 346 individuals with a mean age of 62.1 years for a median duration of 4.1 years (interquartile range [IQR], 2.4-7.9 years). Tear enlargement was seen in 177 shoulders (51.2%), and pain developed in 161 shoulders (46.5%) over time. Tear presence in the dominant shoulder was associated with a greater risk of tear enlargement (hazard ratio, 1.40; P = .03) and pain development (hazard ratio, 1.63; P = .002). Shoulder activity level (P = .37) and occupational demand level (P = .62) were not predictive of tear enlargement. Occupational demand categories of manual labor (P = .047) and "in between" (P = .045) had greater risks of pain development than sedentary demands. The median shoulder activity score for shoulders that became painful was lower than for shoulders that remained asymptomatic (10.0 [IQR, 7.0-13.0] vs. 11.0 [IQR, 8.0-14.0], P = .02). Tear enlargement and pain development in asymptomatic tears are more common with involvement of the dominant shoulder. Shoulder activity level is not related to tear progression risks. Pain development is associated with a lower shoulder activity level even though patients with higher occupational demands are more likely to develop pain.

    The purpose of this study was to evaluate the effects of 12-week aqua walking and jogging program on muscle function, ankle range of motion (ROM), balance and fell efficacy in degenerative lumbar spinal stenosis (DLSS) patients. Six patients (2 males, 4 females) with DLSS participated in aquatic exercise program 3 times per week with each session of 60 min (warming-up, aqua walking, aqua jogging and cool down) at 1 m 20 cm-1 m 30 cm deep pool. Janda's muscle function test, ankle ROM, Berg balance scale (BBS) and fall efficacy scale (FES) were analyzed before and after the training intervention. We found significant increases in balance, muscle function, ankle ROM and fall efficacy after training intervention. In conclusion, aquatic exercise seems to affect physical function and fall efficacy positively in elderly DLSS patients.

    Full Text Available Cumulatively, degenerative disease is one of the most fatal groups of diseases, and it contributes to the mortality and poor quality of life in the world while increasing the economic burden of the sufferers. Oxidative stress and inflammation are the major pathogenic causes of degenerative diseases such as rheumatoid arthritis (RA, diabetes mellitus (DM, and cardiovascular disease (CVD. Although a number of synthetic medications are used to treat these diseases, none of the current regimens are completely safe. Phytochemicals (polyphenols, carotenoids, anthocyanins, alkaloids, glycosides, saponins, and terpenes from natural products such as dietary fruits, vegetables, and spices are potential sources of alternative medications to attenuate the oxidative stress and inflammation associated with degenerative diseases. Based on in vitro, in vivo, and clinical trials, some of these active compounds have shown good promise for development into novel agents for treating RA, DM, and CVD by targeting oxidative stress and inflammation. In this review, phytochemicals from natural products with the potential of ameliorating degenerative disease involving the bone, metabolism, and the heart are described.

    The aim of this study was to test our observation that back pain in thalassemic patients could be caused by premature and extensive lumbar degenerative disc disease, when compared to non-thalassemic patients with back pain. Sixteen thalassemic patients with their sex- and age-matched controls were recruited into the study, 12 with thalassemia major, and 4 with thalassemia intermedia. Both the thalassemia patients and control subjects suffered from back pain, which was subjective rather than measured/pain scored. All subjects underwent magnetic resonance (MR) imaging of the lumbar spine, and 11 of the cases and 8 controls had lumbar spine radiographs. Each lumbar disc was scored for radiographic appearances and MR features of disc degeneration and disc protrusion. Proportion values for these parameters and median scores were derived at each disc level, and were analyzed and compared. There was a statistically-significant difference between proportion values of cases and controls for the MR features (P value=0.01, n=16) and the radiographic features (P value=0.01, n=11 cases, n=8 controls) of disc degeneration. The median disc level scores for the thalassemic group were uniformly high across all lumbar discs, and at all levels except at L 4/5. The control group conversely demonstrated a predilection for disc degeneration at L4/5 level. The distribution of lumbar disc degeneration in thalassemic patients with back pain is more extensive, severe and multi-level in nature compared to matched controls, and disc degeneration should be considered as a significant cause of back pain in this population group.

    As Magnetic Resonance (MR) imaging and Ultrasound (US) allow the evaluation of soft-tissue structures not previously possible with other imaging techniques, a clinical study has been undertaken to determine the value of these 2 modalities in the detection of lesions in the Achilles tendon (AT), other than acute total rupture. Seven healthy subjects and 28 symptomatic patients with Achillodynia and/or signs of thickening of the AT were investigated with MR and US; all results were compared with the clinical features. Surgical findings were available in 14 patients. Patients were divided into 3 groups; those with tendon thickening, incomplete and complete ruptures. Thickening of the AT was easily detected with both methods. MR was superior in the detection of incomplete tendon rupture and in the evaluation of various stages of chronic degenerative changes. It is concluded that only if US remains unclear, an additional MR study should be performed and together with the clinical diagnosis indication for surgery can be made more efficient.

    Industry sponsorship of clinical research of degenerative diseases of the spine has been associated with excessive positive published results as compared to research carried out without industry funding. We sought the rates of publication of clinical trials of degenerative diseases of the spine based on funding source as a possible explanation for this phenomenon. We reviewed all clinical trials registered at clinicaltrials.gov relating to degenerative diseases of the spine as categorized under six medical subject heading terms (spinal stenosis, spondylolisthesis, spondylolysis, spondylosis, failed back surgery syndrome, intervertebral disc degeneration) and with statuses of completed or terminated. These collected studies were categorized as having, or not having, industry funding. Published results for these studies were then sought within the clinicaltrials.gov database itself, PubMed and Google Scholar. One hundred sixty-one clinical trials met these criteria. One hundred nineteen of these trials had industry funding and 42 did not. Of those with industry funding, 45 (37.8%) had identifiable results. Of those without industry funding, 17 (40.5%) had identifiable results. There was no difference in the rates of publication of results from clinical trials of degenerative diseases of the spine no matter the funding source.

    Full Text Available The cerebellum is essentially involved in movement control and plays a critical role in motor learning. It has remained controversial whether patients with degenerative cerebellar disease benefit from high-intensity coordinative training. Moreover, it remains unclear by which training methods and mechanisms these patients might improve their motor performance. Here, we review evidence from different high-intensity training studies in patients with degenerative spinocerebellar disease. These studies demonstrate that high-intensity coordinative training might lead to a significant benefit in patients with degenerative ataxia. This training might be based either on physiotherapy or on whole-body controlled videogames (“exergames”. The benefit shown in these studies is equal to regaining one or more years of natural disease progression. In addition, first case studies indicate that even subjects with advanced neurodegeneration might benefit from such training programs. For both types of training, the observed clinical improvements are paralleled by recoveries in ataxia-specific dysfunctions (e.g., multijoint coordination and dynamic stability. Importantly, for both types of training, the retention of the effects seems to depend on the frequency and continuity of training. Based on these studies, we here present preliminary recommendations for clinical practice, and articulate open questions that might guide future studies on neurorehabilitation in degenerative spinocerebellar disease.

    Full Text Available One of the chronic progressive disorders of the spinal cord in dogs is the degenerative myelopathy (DM. The most predisposed age in dog is 5 to 14 years, while rarely noted in younger, there is no gender predisposition. This disorder most commonly appears in dogs of the German shepherd breed, but it can appear in other breeds too. The main changes about this disease are degeneration of the myelin, especially in the thoracic-lumbar segments of the spinal cord and the dorsal nerve roots. The progression of the disease is slow and can last months to years. Undoubtedly, diagnosis is made by examinations of the CSF and establishing elevated level of protein segments.

    The aim of the present study was to analyze outcome, with respect to functional disability, pain, fusion rate, and complications of patients treated with transforaminal lumbar interbody fusion (TLIF) in compared to instrumented poserolateral fusion (PLF) alone, in low back pain. Spinal fusion has become a major procedure worldwide. However, conflicting results exist. Theoretical circumferential fusion could improve functional outcome. However, the theoretical advantages lack scientific documentation. Prospective randomized clinical study with a 2-year follow-up period. From November 2003 to November 2008 100 patients with severe low back pain and radicular pain were randomly selected for either posterolateral lumbar fusion [titanium TSRH (Medtronic)] or transforaminal lumbar interbody fusion [titanium TSRH (Medtronic)] with anterior intervertebral support by tantalum cage (Implex/Zimmer). The primary outcome scores were obtained using Dallas Pain Questionnaire (DPQ), Oswestry disability Index, SF-36, and low back pain Rating Scale. All measures assessed the endpoints at 2-year follow-up after surgery. The overall follow-up rate was 94 %. Sex ratio was 40/58. 51 patients had TLIF, 47 PLF. Mean age 49(TLIF)/45(PLF). No statistic difference in outcome between groups could be detected concerning daily activity, work leisure, anxiety/depression or social interest. We found no statistic difference concerning back pain or leg pain. In both the TLIF and the PLF groups the patients had significant improvement in functional outcome, back pain, and leg pain compared to preoperatively. Operation time and blood loss in the TLIF group were significantly higher than in the PLF group (p fusion rates was detected. Transforaminal interbody fusion did not improve functional outcome in patients compared to posterolateral fusion. Both groups improved significantly in all categories compared to preoperatively. Operation time and blood loss were significantly higher in the TLIF group.

    Full Text Available Abstract Background The objective of this clinical study is to evaluate the safety and effectiveness of the Activ-L Artificial Disc for treatment of single-level degenerative disc disease of the lumbar spine in patients who have been unresponsive to at least six months of prior conservative care. The hypothesis of the study is that the Activ-L Disc is non-inferior to the control (the Charité® Artificial Disc [DePuy Spine] or ProDisc-L® Total Disc Replacement [Synthes Spine] with respect to the rate of individual subject success at 24 months. Individual subject success is a composite of effectiveness and safety. Methods/Design The study proposed is a prospective, randomized, single-masked, controlled, multi-center clinical trial consisting of an estimated 414 subjects with single-level DDD of the lumbar spine (L4/L5, or L5/S1 who have failed to improve with conservative treatment for at least six months prior to enrollment. After enrollment, subjects will be randomized in a 2:1 ratio to either the Activ-L Disc (investigational device or the control (Charité or ProDisc-L. Radiographic endpoints will be evaluated by an independent reviewer at an imaging core laboratory. Each subject will be followed for 5 years post-treatment. Discussion The safety and effectiveness of the Activ-L Artificial Disc for treatment of single-level degenerative disc disease of the lumbar spine will be equivalent to Charité® Artificial Disc [DePuy Spine] or ProDisc-L® Total Disc Replacement [Synthes Spine] at 24 months.

    Objectives: Nucleoplasty is a minimally invasive procedure that is developed to treat patients with symptomatic, but contained disc herniations or bulging discs. The purpose of this study was to evaluate a decade follow-up of coblation nucleoplasty treatment for protruded lumbar intervertebral disc. Methods: In this retrospective study there a total 50 patients who underwent intradiscal coblation therapy for symptomatic, but contained lumbar degenerative disc disease were included. Relief of low back pain, leg pain and numbness after the operation were assessed by visual analog pain scale (VAS). Function of lower limb and daily living of patients were evaluated by the Oswestry disability index (ODI) and subjective global rating of overall satisfaction were recorded and analyzed. Results: There were 27 male and 23 female with followup mean follow up of 115 months (range 105–130 months) with a mean age was 52 years (range 26–74 years). Analgesic consumption was reduced or stopped in 90% of these cases after 1 year. At 24 months follow up VAS was four points and ODI was 7.2. In three patients, we repeated the cool ablation after 36 months, at L3–4 level in two cases. Ten patients continue to be asymptomatic after 114 months of intervention. There were no complications with the procedure including nerve root injury, discitis or allergic reactions. Conclusions: Nucleoplasty may provide intermittent relief in contained disc herniation without significant complications and minimal morbidity. In accordance with the literature the evidence for intradiscal coablation therapy is moderate in managing chronic discogenic low back pain; nucleoplasty appears to be safe and effective.

    Herrmann, Wolfgang; Knapp, Jean-Pierre

    2002-01-01

    Hyperhomocysteinemia (HHCY) is a consequence of disturbed methionine metabolism. It results from enzyme and/or vitamin deficiency. Epidemiological and clinical studies have proven HHCY to be an independent risk factor for atherosclerotic cardiovascular diseases, stroke, peripheral arterial occlusive disease and venous thrombosis. Trials in progress may clarify the "causality" of high homocysteine (HCY) concentrations and will assess the value of HCY lowering therapy. HHCY is also seen as a risk factor for neurodegenerative diseases such as cognitive impairment, dementia, Alzheimer's disease, and also for depression. There is a high prevalence of HHCY as a syndrome of vitamin shortage in elderly subjects, which strongly increases with advancing age. Elderly people have a high frequency of vitamin B12 deficiency which is more reliably diagnosed by measurement of serum methylmalonic acid and holotranscobalamin II, the metabolically active B12 fraction, than by total serum vitamin B12. Subjects who follow a strict vegetarian diet also have a high prevalence of HHCY caused by vitamin B12 deficiency. For prevention of neurological damages an early diagnosis of vitamin B12 deficiency is important. Furthermore, HHCY is a factor in the pathogenesis of neural tube defects and preeclampsia. HCY should be measured in patients with a history of atherothrombotic vessel diseases, in patients with diabetes or hyperlipidemia, in renal patients, in adipose subjects, in elderly people, in vegetarians, in postmenopausal women, and in early pregnancy.

    To evaluate the role that post-operative difference value of pelvic incidence and lumbar lordosis (PI-LL) played on loss of correction, implant failure and health-related quality of life during follow-up in degenerative scoliosis patients. Retrospective review of 62 patients (average age (57 ± 10) years, 11 male and 51 female patients) with degenerative scoliosis who underwent one stage posterior surgical instrumentation in the affiliated Drum Tower Hospital of Nanjing University Medical School from January 2005 to December 2011. The mean follow-up duration was 4.2 years. Long-cassette standing upright sagittal radiographs were obtained before and after operation and at the last follow-up. At the last follow-up, visual analogue scale and Oswestry disability index were collected. Based on post-operative PI-LL, patients were divided into two groups: group A (-9° 9°). Independent t test and χ(2) test were performed for statistical analysis. For all statistical analysis, the level of significance was set at P < 0.05. No difference was observed in terms of loss of correction between two groups during follow-up. More implant failure were observed in group B (15.63% vs. 6.7%, χ(2) = 21.85, P = 0.012). In addition, patients with better PI-LL matching came with better visual analogue scale (3.9 ± 2.4 vs. 5.2 ± 3.3, F = 0.089, P = 0.024). Worse quality of life and increased risk for implant failure during follow-up may be related to mismatched PI-LL.

    Full Text Available Abstract Background Degenerative spinal stenosis and instability requiring multilevel spine surgery has been associated with large blood losses. Factors that affect perioperative blood loss include time of surgery, surgical procedure, patient height, combined anterior/posterior approaches, number of levels fused, blood salvage techniques, and the use of anti-fibrinolytic medications. This study was done to evaluate the efficacy of tranexamic acid in reducing blood loss in spine surgery. Methods This retrospective case control study includes 97 patients who had to undergo surgery because of degenerative lumbar spinal stenosis and instability. All operations included spinal decompression, interbody fusion and posterior instrumentation (4-5 segments. Forty-six patients received 1 g tranexamic acid intravenous, preoperative and six hours and twelve hours postoperative; 51 patients without tranexamic acid administration were evaluated as a control group. Based on the records, the intra- and postoperative blood losses were measured by evaluating the drainage and cell saver systems 6, 12 and 24 hours post operation. Additionally, hemoglobin concentration and platelet concentration were reviewed. Furthermore, the number of red cell transfusions given and complications associated with tranexamic acid were assessed. Results The postoperative hemoglobin concentration demonstrated a statistically significant difference with a p value of 0.0130 showing superiority for tranexamic acid use (tranexamic acid group: 11.08 g/dl, SD: 1.68; control group: 10.29 g/dl, SD: 1.39. The intraoperative cell saver volume and drainage volume after 24 h demonstrated a significant difference as well, which indicates a less blood loss in the tranexamic acid group than the control group. The postoperative drainage volume at12 hours showed no significant differences; nor did the platelet concentration Allogenic blood transfusion (two red cell units was needed for eight patients

    Degenerative disease of the lumbar spine is a common and increasingly prevalent condition that is often implicated as the primary reason for chronic low back pain and the leading cause of disability in the western world. Surgical management of lumbar degenerative disease has historically been approached by way of open surgical procedures aimed at decompressing and/or stabilizing the lumbar spine. Advances in technology and surgical instrumentation have led to minimally invasive surgical techniques being developed and increasingly used in the treatment of lumbar degenerative disease. Compared to the traditional open spine surgery, minimally invasive techniques require smaller incisions and decrease approach-related morbidity by avoiding muscle crush injury by self-retaining retractors, preventing the disruption of tendon attachment sites of important muscles at the spinous processes, using known anatomic neurovascular and muscle planes, and minimizing collateral soft-tissue injury by limiting the width of the surgical corridor. The theoretical benefits of minimally invasive surgery over traditional open surgery include reduced blood loss, decreased postoperative pain and narcotics use, shorter hospital length of stay, faster recover and quicker return to work and normal activity. This paper describes the different minimally invasive techniques that are currently available for the treatment of degenerative disease of the lumbar spine. PMID:25610845

    Through the consultation of TCM ancient classical theory, the relationship of kidney essence, marrow and brain is analyzed. It is discovered that the degenerative brain diseases, represented by Alzheimer's disease (AD) and Parkinson's disease (PD) share the same etiological basis as "kidney essence deficiency and brain marrow emptiness" and have the mutual pathological outcomes as yang qi declining. The Governor Vessel gathers yang qi of the whole body and maintains the normal functional activity of zangfu organs in the human body through the storage, regulation and invigoration of yang qi. It is viewed that the theory of the Governor Vessel is applied to treat the different degenerative brain diseases, which provides the theoretic support and practice guide for the thought of TCM as the same therapeutic program for the different diseases. As a result, the degenerative brain diseases can be retarded and the approach is provided to the effective prevention and treatment of degenerative diseases in central nerve system:

    Lumbar fusion has become a major surgical method in the treatment of lumbar degenerative diseases. Transforaminal lumbar interbody fusion ( TLIF ) has a series of advantages such as less damage to lumbar structure, less nerve injuries and less postoperative complications. With the constant increase of lumbar degenerative diseases, TLIF has been rapidly developed in recent years. With the development of surgery, minimally invasive technique has been used in TLIF. Minimally invasive-TLIF ( MI-TLIF ) has become one of the research hotspots in spinal surgery. The development process, technical features, biomechanical advantages, internal ifxation methods and fusion materials of TLIF and MI-TLIF are reviewed in this paper.

    The visual cycle is a sequential enzymatic reaction for vitamin A, all-trans-retinol, occurring in the outer layer of the human retina and is essential for the maintenance of vision. The central source of retinol is derived from dietary intake of both retinol and pro-vitamin A carotenoids. A series of enzymatic reactions, located in both the photoreceptor outer segment and the retinal pigment epithelium, transform retinol into the visual chromophore 11-cis-retinal, regenerating visual pigments. Retina specific proteins carry out the majority of the visual cycle, and any significant interruption in this sequence of reactions is capable of causing varying degrees of blindness. Among these important proteins are Lecithin:retinol acyltransferase (LRAT) and retinal pigment epithelium-specific 65-kDa protein (RPE65) known to be responsible for esterification of retinol to all-trans-retinyl esters and isomerization of these esters to 11-cis-retinal, respectively. Deleterious mutations in these genes are identified in human retinal diseases that cause blindness, such as Leber congenital amaurosis (LCA) and retinitis pigmentosa (RP). Herein, we discuss the pathology of 11-cis-retinal deficiency caused by these mutations in both animal disease models and human patients. We also review novel therapeutic strategies employing artificial visual chromophore 9-cis-retinoids which have been employed in clinical trials involving LCA patients.

    Degenerative retinal diseases affect millions of people worldwide, which can lead to the loss of vision. However, therapeutic approaches that can reverse this process are limited. Recent efforts have allowed the possibility of the stem cell-based regeneration of retinal cells and repair of injured retinal tissues. Although the direct differentiation of pluripotent stem cells into terminally differentiated photoreceptor cells comprises one approach, a series of studies revealed the intrinsic regenerative potential of the retina using endogenous retinal stem cells. Muller glial cells, ciliary pigment epithelial cells, and retinal pigment epithelial cells are candidates for such retinal stem cells that can differentiate into multiple types of retinal cells and be integrated into injured or developing retina. In this review, we explore our current understanding of the cellular identity of these candidate retinal stem cells and their therapeutic potential for cell therapy against degenerative retinal diseases.

    Neuroimaging offers a powerful means to assess the trajectory of brain degeneration in a variety of disorders, including Alzheimer's disease (AD). Here we describe how multi-modal imaging can be used to study the changing brain during the different stages of AD. We integrate findings from a range of studies using magnetic resonance imaging (MRI), positron emission tomography (PET), functional MRI (fMRI) and diffusion weighted imaging (DWI). Neuroimaging reveals how risk genes for degenerative disorders affect the brain, including several recently discovered genetic variants that may disrupt brain connectivity. We review some recent neuroimaging studies of genetic polymorphisms associated with increased risk for late-onset Alzheimer's disease (LOAD). Some genetic variants that increase risk for drug addiction may overlap with those associated with degenerative brain disorders. These common associations offer new insight into mechanisms underlying neurodegeneration and addictive behaviors, and may offer new leads for treating them before severe and irreversible neurological symptoms appear.

    To evaluate the short-term and long-term effects of fluoroscopically guided caudal epidural steroid injection (ESI) for the management of degenerative lumbar spinal stenosis (DLSS) and to analyze outcome predictors. All patients who underwent caudal ESI in 2006 for DLSS were included in the study. Response was based on chart documentation (aggravated, no change, slightly improved, much improved, no pain). In June 2009 telephone interviews were conducted, using formatted questions including the North American Spine Society (NASS) patient satisfaction scale. For short-term and long-term effects, age difference was evaluated by the Mann-Whitney U test, and gender, duration of symptoms, level of DLSS, spondylolisthesis, and previous operations were evaluated by Fisher's exact test. Two hundred and sixteen patients (male: female = 75:141; mean age 69.2 years; range 48{proportional_to}91 years) were included in the study. Improvements (slightly improved, much improved, no pain) were seen in 185 patients (85.6%) after an initial caudal ESI and in 189 patients (87.5%) after a series of caudal ESIs. Half of the patients (89/179, 49.8%) replied positively to the NASS patient satisfaction scale (1 or 2). There were no significant outcome predictors for either the short-term or the long-term responses. Fluoroscopically guided caudal ESI was effective for the management of DLSS (especially central canal stenosis) with excellent short-term and good long-term results, without significant outcome predictors.

    Human pluripotent stem cells represent a unique source for cell-based therapies and regenerative medicine. The intrinsic features of these cells such as their easy accessibility and their capacity to be expanded indefinitely overcome some limitations of conventional adult stem cells. Furthermore, the possibility to derive patient-specific induced pluripotent stem (iPS) cells in combination with the current development of gene modification methods could be used for autologous cell therapies of some genetic diseases. In particular, muscular dystrophies are considered to be a good candidate due to the lack of efficacious therapeutic treatments for patients to date, and in view of the encouraging results arising from recent preclinical studies. Some hurdles, including possible genetic instability and their efficient differentiation into muscle progenitors through vector/transgene-free methods have still to be overcome or need further optimization. Additionally, engraftment and functional contribution to muscle regeneration in pre-clinical models need to be carefully assessed before clinical translation. This review offers a summary of the advanced methods recently developed to derive muscle progenitors from pluripotent stem cells, as well as gene therapy by gene addition and gene editing methods using ZFNs, TALENs or CRISPR/Cas9. We have also discussed the main issues that need to be addressed for successful clinical translation of genetically corrected patient-specific pluripotent stem cells in autologous transplantation trials for skeletal muscle disorders.
