    Full Text Available BACKGROUND: With the properties of three-column fixation and anterior-approach-only procedure, anterior transpedicular screw (ATPS is ideal for severe multilevel traumatic cervical instabilities. However, the accurate insertion of ATPS remains challenging. Here we constructed a patient-specific biocompatible drill template and evaluated its accuracy in assisting ATPS insertion. METHODS: After ethical approval, 24 formalin-preserved cervical vertebrae (C2-C7 were CT scanned. 3D reconstruction models of cervical vertebra were obtained with 2-mm-diameter virtual pin tracts at the central pedicles. The 3D models were used for rapid prototyping (RP printing. A 2-mm-diameter Kirschner wire was then inserted into the pin tract of the RP model before polymethylmethacrylate was used to construct the patient-specific biocompatible drill template. After removal of the anterior soft tissue, a 2-mm-diameter Kirschner wire was inserted into the cervical pedicle with the assistance of drill template. Cadaveric cervical spines with pin tracts were subsequently scanned using the same CT scanner. A 3D reconstruction was performed of the scanned spines to get 3D models of the vertebrae containing the actual pin tracts. The deviations were calculated between 3D models with virtual and actual pin tracts at the middle point of the cervical pedicle. 3D models of 3.5 mm-diameter screws were used in simulated insertion to grade the screw positions. FINDINGS: The patient-specific biocompatible drill template was constructed to assist ATPS insertion successfully. There were no significant differences between medial/lateral deviations (P = 0.797 or between superior/inferior deviations (P = 0.741. The absolute deviation values were 0.82±0.75 mm and 1.10±0.96 mm in axial and sagittal planes, respectively. In the simulated insertion, the screws in non-critical position were 44/48 (91.7%. CONCLUSIONS: The patient-specific drill template is biocompatible, easy

  2. SURVEY SUBAXIAL CERVICAL VERTEBRAE FOR TRANSPEDICULAR SCREW FIXATION

    Objective In this study, the pedicles of subaxial vertebrae from C3 to C7 were measured to provide some morphometric data for cervical transpedicular screw fixation. Methods 20 dried bone cervical spinal columns (C3-C7), pedicle dimensions (pedicle height, width, length), and transverse and sagittal angles of the pedicles were performed with vernier in linear and angular measurements. Results The obtained data revealed that the mean values were approximately ranging from 6.7 to 7.2 mm for pedicle height, 4.4 to 4.9 mm for pedicle width, 22.2 to 27.7 mm for pedicle axis length, 42.3° to 51.5° for transverse angle, and 5.2° to 14.1° for sagittal angle. Conclusion Linear measurements of pedicle dimensions and also axial angles from horizontal and vertical planes may provide some anatomic limitations for subaxial cervical transpedicular screw fixation, and also contribute to the safety of the surgical procedure.

    Full Text Available Background: Cervical transpedicular screw fixation is safe and is probably going to be the gold standard for cervical spine fixation. However, cervical transpedicular screw use in the Asian population can be limited as the transverse diameter in this group of patients may not be adequate to accommodate the 3.5-mm pedicular screw thus injuring the vital structures located in the close proximity of the pedicles. Thus lateral mass fixation remains the mainstay of treatment. The present study evaluated the transverse cervical pedicle diameter of C2-C7 vertebrae in a pilot study in 27 Indian subjects using computed tomography (CT imaging and evaluated the feasibility of transpedicular screw fixation in them. Aims: To evaluate the feasibility of transpedicular screw fixation in the Indian population. Settings and Design: The cervical pedicle diameter size differs between the Asian and non-Asian population. The authors studied the transverse pedicle diameter of the C2-C7 of the cervical spine in the Indian population using CT measurements. This cross-sectional study was carried out at a tertiary care centre for a period of four months from October 2010 to December 2010. Material and Methods: Measurements of cervical pedicles in the subjects were performed on the CT workstation from the CT images taken at 2.5-mm interval. The transverse pedicle diameter was defined as the outermost diameter of the pedicle, taken perpendicular to the axis of the pedicle at the narrowest point and measured in millimeters±0.1 mm. Statistical Analysis: Descriptive statistics was used to represent percentage of transverse diameter of cervical pedicles less than 5 mm in male and female subjects at C2-C7 levels. Since there is no previous study done in India, we initiated the study with sample size of 27 as a pilot study. The statistical analysis was performed using SPSS software. Results: The mean transverse diameters of the cervical pedicles of C2, C3, C4, C5, C6 and C7 in

    Full Text Available Objective: Cervical laminectomies with transpedicular insertion technique is known to be a biomechanically stronger method in cervical pathologies. However, its frequency of use is low in the routine practice, as the pedicle is thin and risk of neurovascular damage is high. In this study, we emphasize the results of cervical laminectomies with transpedicular fixation using fluoroscopy in degenerative cervical spine disorder. Materials and Methods: Postoperative malposition of the transpedicular screws of the 70 pedicles of the 10 patients we operated due to degenerative stenosis in the cervical region, were investigated. Fixation was performed between C3 and C7, and we used resected lamina bone chips for fusion. Clinical indicators included age, gender, neurologic status, surgical indication, and number of levels stabilized. Dominant vertebral artery of all the patients was evaluated with Doppler ultrasonography. Preoperative and postoperative Nurick grade of each patient was documented. Results: No patients experienced neurovascular injury as a result of pedicle screw placement. Two patients had screw malposition, which did not require reoperation due to minor breaking. Most patients had 32-mm screws placed. Postoperative computed tomography scanning showed no compromise of the foramen transversarium. A total of 70 pedicle screws were placed. Good bony fusion was observed in all patients. At follow-up, 9/10 (90% patients had improved in their Nurick grades. The cases were followed-up for an average of 35.7 months (30-37 months. Conclusions: Use of the cervical pedicular fixation (CPF provides a very strong three-column stabilization but also carries vascular injury without nerve damage. Laminectomies technique may reduce the risk of malposition due to visualization of the spinal canal. CPF can be performed in a one-stage posterior procedure. This technique yielded good fusion rate without complications and can be considered as a good

    Full Text Available Radiologist always examines X-ray to determine abnormal changes in cervical, lumbar & thoracic vertebrae. Osteophyte (bony growth may appear at the corners of vertebrae so that vertebral shape becomes abnormal. This paper presents the idea from Image processing techniques such as customised Hough transform which will be used for segmentation which should be independent of rotation, scale, noise & shape. This segmented image will be then used for computing size invariant, convex hull based features to differentiate normal cervical vertebrae from cervical vertebrae containing anterior osteophyte. This approach effectively finds anterior osteophytes in cervical vertebrae.

    Anterior cervical fusion has become a standard of care for numerous pathologic conditions of the cervical spine. However, subsequent development of clinically significant disc disease at levels adjacent to fused discs is a serious long-term complication of this procedure. As more patients live longer after surgery, it is foreseeable that adjacent segment pathology (ASP) will develop in increasing numbers of patients. Also, ASP has been studied more intensively with the recent popularity of motion preservation technologies like total disc arthroplasty. The true nature and scope of ASP remains poorly understood. The etiology of ASP is most likely multifactorial. Various factors including altered biomechanical stresses, surgical disruption of soft tissue and the natural history of cervical disc disease contribute to the development of ASP. General factors associated with disc degeneration including gender, age, smoking and sports may play a role in the development of ASP. Postoperative sagittal alignment and type of surgery are also considered potential causes of ASP. Therefore, a spine surgeon must be particularly careful to avoid unnecessary disruption of the musculoligamentous structures, reduced risk of direct injury to the disc during dissection and maintain a safe margin between the plate edge and adjacent vertebrae during anterior cervical fusion.

    Full Text Available The anterior retropharyngeal approach (ARPA accesses anteriorly situated lesions from the clivus to C3, in patients with a short neck, Klippel Feil anomaly or those in whom the C2-3 and C3-4 disc spaces are situated higher in relation to the hyoid bone and the angle of mandible where it is difficult to approach this region using the conventional anterior approach, due to the superomedial obliquity of the trajectory. The ARPA avoids the potentially contaminated oropharyngeal cavity providing for a simultaneous arthrodesis and instrumentation during the primary surgical procedure. Experience of five patients with high cervical extradural compression, who underwent surgery using this approach between 1994 and 1999, is presented. The surgical procedures included excision of ossified posterior longitudinal ligament (n=2; excision of prolapsed disc and osteophytes (n=2; and excision of a vertebral body neoplasm (n=1. Following the procedure, vertebral arthrodesis was achieved using an iliac graft in all the patients. Only one patient with vertebral body neoplasm required an additional anterior cervical plating procedure for stabilisation the construct. The complications included transient respiratory insufficiency and neurological deterioration in two patients; and, pharyngeal fistula and donor site infection in one patient.

    Full Text Available Background: Although microscopic anterior cervical discectomy with or without fusion are common surgical procedures for treatment of cervical herniated discs, loss of disc height, pseudarthrosis, and adjacent disc degeneration are some of the problems associated with it. This study is aimed to evaluate results of endoscopic microforaminotomy in cervical disc diseases. Materials and Methods: A prospective study of 50 patients of mono segmental soft or hard disc causing myeloradiculopathy was undertaken. A visual analogue scale (VAS for neck and arm pain and functional outcomes using the Nurick grading system were assessed. There were 28, 12, 8, and 2 patients at C5-6, C6-7, C4-5, and C3-4 levels disc diseases, respectively. Patients with two or more level disc, instabilities, disc extending more than half vertebral body height, and previous operation at the same segment were excluded. Results: Age ranged from 21 to 67 years. Average postoperative reduction in disc height, operating time, and blood loss was 1.1 mm, 110 minutes, and 30 ml, respectively. Average pre-operative VAS score for arm pain and Nurick grading was 7.6 and 2.7, which improved to 1.9 and 0.82, respectively. All patients improved; 1, 2, 3 grade improvement was seen in 10, 27, and 10 patients, respectively. There was no significant complication or any mortality. Conclusion: Although longer follow up of large number of patients is required, endoscopic microforaminotomy is a safe and an effective alternative to microscopic anterior discectomy with or without fusion.

    Full Text Available Background: Noncontiguous cervical spondylotic myelopathy (CSM is a special degenerative disease because of the intermediate normal level or levels between supra and infraabnormal levels. Some controversy exists over the optimal procedure for two noncontiguous levels of CSM. The study was to evaluate the outcomes of the anterior cervical discectomy and fusion (ACDF with zero-profile devices for two noncontiguous levels of CSM. Materials and Methods: 17 consecutive patients with two noncontiguous levels of CSM operated between December 2009 and August 2012 were included in the study. There were 12 men and 5 women with a mean age of 60.7 years (range 45-75 years. Involved disc levels were C3/4 and C5/6 in 11 patients and C4/5 and C6/7 in six patients. Preoperative plain radiographs, computed tomography (CT with 3-D reconstruction and magnetic resonance imaging (MRI of the cervical spine were taken in all patients. All radiographs were independently evaluated by 2 spine surgeons and 1 radiologist. The outcomes were assessed by the average operative time, blood loss, Japanese Orthopedic Association (JOA score, improvement rate, neck dysfunction index (NDI, swallowing quality of life (SWAL-QOL score, the cervical lordosis and complications. Results: The mean followup was 48.59 months (range 24-56 months. The average operative time and blood loss was 105.29 min and 136.47 ml, respectively. The preoperative JOA score was 8.35, which significantly increased to 13.7 at the final followup ( P 0.05. Cerebrospinal fluid leak, dysphagia and radiological adjacent segment degeneration occurred in one patient, respectively. Conclusion: The ACDF with zero-profile devices is generally effective and safe in treating two noncontiguous levels of CSM.

    Full Text Available Although anterior cervical arthrodesis is an effective procedure for the treatment of cervical disorders, the method has some complications. Here, we describe this rare complication of cervical instrumentation with a literature review. A 23-year-old male patient was operated for a C6-C7 dislocation. At postoperative month 10, he presented with hemoptysis and dysphagia. Cervical roentgenograms showed anterior migrations of one broken screw and a plate-locking screw at the C6 corpus. One screw was missing. We concluded that the missing screw had perforated the esophagus and had been eliminated spontaneously through the gastrointestinal tract. No screw should migrate. Even loose screws should be noted in follow-up X-ray studies. If such findings are detected, a second operation for revision should be considered as soon as possible to prevent potentially fatal complications.

METHODS: Prospective and descriptive study was conducted from January 2009 to April 2010. All patients who underwent arthrodesis of the cervical spine by anterior approach were included, regardless the diagnosis. Access was made by the anterior approach on the right side. We evaluated the number of operated levels (1, 2 or 3 levels and, the type of procedure performed: discectomy and placement of cage and plate (D+C+P, discectomy with placement of a cage (D+C or corpectomy with placement of cage and plate (C+C+P. All complications related to surgical approach were reported. RESULTS: We studied 34 patients, 70% male. The average age was 50 years and mean follow-up was 8 months. Eighteen percent of patients had complications, distributed as follows: dysphasia (33% and dysphonic (67%. Among patients who developed complications, most underwent to D+C+P (83% and no complications were found in patients where no cervical plate was used. Regarding levels, both complications were identified in patients operated to one or two levels. However, in patients operated on three levels, only dysphonia was identified. CONCLUSION: The most frequent complication was dysphonia. Patients who presented more complications were those undergoing discectomy and fusion with cage and anterior cervical plate. All cases of dysphonia were in this group. The number of accessible levels does not seem to have affected the incidence of complications.

    Three patients developed signs of a unilateral cervical cord lesion 6 to 36 h after the acute onset of severe cervico-brachial pain. The neurological deficit progressed over 6 to 18 h. On the painful side a central Horner's syndrome, a hemiparesis with plegia of the hand, and a slight pallhypaesthesia were found. On the opposite side thermhypaesthesia and hypalgesia were noted with a level at the dermatome C5 or C6. T2-weighted MR images revealed in one patient a small area of increased signal intensity restricted to one half of the cervical cord, and electromyography in another patient showed after 6 months evidence of segmental chronic denervation. Both abnormalities were found at the clinically expected level. The findings are consistent with a small infarction of the cervical cord in the perfusion territory of a central (sulco-commissural) artery, a duplicated anterior spinal artery or an anterior spinal branch of the vertebral artery.

    Background A considerable number of patients with cervical spondylosis complain about one or multiple atypical symptoms such as vertigo, palpitations, headache, blurred vision, hypomnesia, and/or nausea. It remains unclear whether surgical intervention for cervical spondylosis can also effectively alleviate those symptoms. The current study was performed to see if anterior cervical diskectomy and fusion (ACDF) offers such an extra benefit for patients with cervical spondylosis. Objective To investigate if patients who received ACDF for the treatment of cervical spondylotic myelopathy and/or radiculopathy can also achieve alleviation of certain atypical symptoms associated with cervical spondylosis after the surgery in the long run. Methods Sixty-seven patients who underwent ACDF for the treatment of cervical spondylotic myelopathy and/or radiculopathy were involved in this study. All these patients also complained about various associated atypical symptoms. They were followed up for 26 to 145 months after the surgery. Severity and frequency scores of the atypical symptoms before the surgery and at last follow-up were compared by paired t tests. Results Most patients reported significantly alleviated symptoms at the last follow-up compared with before the surgery. The severity of vertigo, headache, nausea, and palpitations were significantly alleviated at the last follow-up (with p values of p cervical spondylotic myelopathy and/or radiculopathy, but it is not effective in alleviating symptoms such as tinnitus, blurred vision, and hypomnesia. It can be considered for alleviating atypical symptoms when other treatment options prove ineffective. PMID:27168319

    Conclusion: ACDF has been demonstrated to be an effective surgical procedure in treating degenerative spine disease in patients with radiculopathy and/or myelopathy. However, in a population with isolated radiculopathy and radiological imaging confirming an anterolateral disc or osteophyte complex, the MIPKF can provide similar results without the associated risks that accompany an anterior cervical spine fusion.

    2007-01-01

    Objective:To investigate a novel surgical method for multilevel cervical spondylotic myelopathy (CSM). Methods: Totally 21 patients with multilevel CSM undergoing a novel surgical procedure from April 2001 to January 2004 were analyzed retrospectively. All patients experienced anterior cervical decompression surgery in subsection, autograft fusion and internal fixation. Preoperative, immediate postoperative and follow-up image data, X-rays and semi-quantitative Japanese orthopaedics association (JOA) scores were used to evaluate the restoration of lordosis (Cobb's angle), intervertebral heights, the stability of the cervical spine and the improvement of neurological impairment. Results: Preoperative symptoms were markedly alleviated or disappeared in most of the patients. According to the JOA scores, the ratio of improvement in neurological function was 72.2%, including excellent in 9 cases (42.9%), good in 7 cases (33.3%), fair in 3 cases (14.3%) and poor in 2 cases (9.5%). Immediate postoperative X-rays showed obvious improvements in lordosis and in the intervertebral height of the cervical spine (P<0.01). There is no evidence of instrument failure during the mean follow-up period of 14.2 months (9-24 months, P>0.01). Conclusion:Anterior cervical decompression in subsection, autograft fusion and internal fixation is a rational effective method for the surgical treatment of multilevel CSM.

    This study was aimed to explore the anterior cervical surgery methods to treat central cord syndrome without radiographic spinal fracture-dislocation (CCSWORFD), retrospectively analyze the cases of CCSWORFD, and evaluate the curative effect of anterior cervical surgery methods for CCSWORFD. Twenty four cases of CCSWORFD (19 males and 5 females), all suffering from cervical hyperextension injury, between 45-68 (average 59) years old, were operated on by anterior cervical surgery methods. Among these, 18 cases had been followed up for 6-24 (average 15) months; 18 cases, who had anterior decompression and plate fixation with titanium mesh bone grafting or iliac bone grafting achieved reliable effects based on the Japanese Orthopedics Association (JOA) evaluation (improved scores of cases with titanium mesh bone grafting, t = 2.800, P0.05). Most of these cases had degeneration of cervical vertebra. The decompression which relieves the oppression to the spinal cord can help lessen edema of the spinal cord, and early fixation for stability of cervical vertebra is better for the recovery of spinal cord injury. Anterior operation with titanium mesh bone grafting or iliac bone grafting are both reliable curative methods for CCSWORFD, and titanium mesh bone grafting can avoid the trauma of the supplying graft. Mesh bone grafting can also shorten hospital stay.

    Anterior cervical decompression for two or more cervical spondylotic levels can be performed using either multiple anterior cervical discectomies and fusion or anterior cervical corpectomy and fusion (ACCF). A variety of options for ACCF implants exist but to our knowledge, there is no clinical data for the use of tantalum trabecular metal implants (TTMI) for ACCF. A retrospective review was performed of prospectively collected data for ten patients undergoing ACCF with TTMI between 2011 and 2012. Radiological outcome was assessed by measuring the change in cervical (C) lordosis (fusion Cobb and C2-C7 Cobb), graft subsidence (anterior/posterior, determined by the subsidence of anterior/posterior body height of fused segments; cranial/caudal, determined by the cranial/caudal plate-to-disc distances) and rate of fusion using lateral cervical X-rays of patients at 0, 6, 12 and 24months post-operatively. The Neck Disability Index (NDI) assessed clinical outcome pre-operatively and at 6, 12 and 24months post-operatively. Cervical lordosis (Cobb angle of fused segment) was 5.2° (± 4.2°) at 0months and 6.0° (± 5.7°) at 24months post-operatively. Graft subsidence was observed to occur at 6months post-operatively and continued throughout follow-up. Anterior, posterior and caudal subsidence occurred more in the first 12months post-operatively than in the following 12months (p<0.05). Average pre-operative NDI was 45%. Average NDIs were 18%, 13% and 10% at 6, 12 and 24months post-operatively, respectively. ACCF patients treated with TTMI demonstrated stable cervical lordosis over 2years of follow-up and 100% fusion rates after 2years. Measures of subsidence appeared to decrease with time. Patients experienced improved clinical outcomes over the 2-year period. PMID:27515543

    To investigate the outcomes and reliability of hybrid surgery (HS) versus anterior cervical discectomy and fusion (ACDF) for the treatment of multilevel cervical spondylosis and disc diseases.Hybrid surgery, combining cervical disc arthroplasty (CDA) with fusion, is a novel treatment to multilevel cervical degenerated disc disease in recent years. However, the effect and reliability of HS are still unclear compared with ACDF.To investigate the studies of HS versus ACDF in patients with multilevel cervical disease, electronic databases (Medline, Embase, Pubmed, Cochrane library, and Cochrane Central Register of Controlled Trials) were searched. Studies were included when they compared HS with ACDF and reported at least one of the following outcomes: functionality, neck pain, arm pain, cervical range of motion (ROM), quality of life, and incidence of complications. No language restrictions were used. Two authors independently assessed the methodological quality of included studies and extracted the relevant data.Seven clinical controlled trials were included in this study. Two trials were prospective and the other 5 were retrospective. The results of the meta-analysis indicated that HS achieved better recovery of NDI score (P = 0.038) and similar recovery of VAS score (P = 0.058) compared with ACDF at 2 years follow-up. Moreover, the total cervical ROM (C2-C7) after HS was preserved significantly more than the cervical ROM after ACDF (P = 0.000) at 2 years follow-up. Notably, the compensatory increase of the ROM of superior and inferior adjacent segments was significant in ACDF groups at 2-year follow-up (P multilevel cervical spondylosis to preserve cervical ROM and reduce the risk of adjacent disc degeneration. Nonetheless, more well-designed studies with large groups of patients are required to provide further evidence for the benefit and reliability of HS for the treatment of cervical disk diseases.

    The primary aim of this study was to conduct a systematic review of reports of patients with cervical spondylotic myelopathy and to assess the value of intraoperative monitoring (IOM), including somatosensory evoked potentials, transcranial motor evoked potentials and electromyography, in anterior cervical procedures. A search was conducted to collect a small database of relevant papers using key words describing disorders and procedures of interest. The database was then shortlisted using selection criteria and data was extracted to identify complications as a result of anterior cervical procedures for cervical spondylotic myelopathy and outcome analysis on a continuous scale. In the 22 studies that matched the screening criteria, only two involved the use of IOM. The average sample size was 173 patients. In procedures done without IOM a mean change in Japanese Orthopaedic Association score of 3.94 points and Nurick score by 1.20 points (both less severe post-operatively) was observed. Within our sub-group analysis, worsening myelopathy and/or quadriplegia was seen in 2.71% of patients for studies without IOM and 0.91% of patients for studies with IOM. Variations persist in the existing literature in the evaluation of complications associated with anterior cervical spinal procedures. Based on the review of published studies, sufficient evidence does not exist to make recommendations regarding the use of different IOM modalities to reduce neurological complications during anterior cervical procedures. However, future studies with objective measures of neurological deficits using a specific IOM modality may establish it as an effective and reliable indicator of injury during such surgeries.

    Introduction Cervical spondylotic myelo-radiculopathy is a form of spinal cord dysfunction syndrome and usually accompanies age related degeneration of the spine. Aim To determine the functional outcome of anterior cervical discectomy with fusion and plating in single level degenerative cervical disc prolapse. Materials and Methods A total of 20 patients diagnosed with degenerative single level cervical disc prolapse who presented to the Department of Orthopaedic Surgery, Justice KS Hegde Charitable Hospital, Mangalore from the period of November 2012 to May 2014 were enrolled in the study. Complete clinical and radiological evaluation of the patients was done. A trial of conservative management was tried in all these patients for a period of two months. They were taken up for surgery only when conservative management had failed. Scoring of neck function before the surgery was done as per the Modified Japanese Orthopaedic Association (MJOA) score. All patients underwent anterior cervical discectomy and fusion (ACDF) with tricortical iliac crest bone grafting. Fixation was performed with titanium locking cervical plates. All patients were reviewed at 6 weeks and 6 months postoperatively. Assessment of neck function was done as per the MJOA scoring during all the reviews. Radiographic assessment was also done during all the reviews. The complications noted were documented. The statistical analysis was done using percentages; the arithmetic mean was calculated using SPSS software (version 16.0). Results Amongst the 20 patients included in the study, 1 patient died postoperatively due to oesophageal rupture. of the remaining 19 patients reviewed and followed up, all of them had improvement of symptoms and were reported to be in the ‘mild category’ as per the MJOA score. One patient developed dysphonia, in the immediate postoperative period due to recurrent laryngeal nerve palsy which recovered in a period of three months postoperative. Conclusion Single level

    The purpose of this article is to introduce and analyze the feasibility of simultaneously combined anterior-posterior approaches for subaxial cervical circumferential reconstruction in sitting position. A retrospective case review was performed for above surgery procedure. A 79-year-old man was confirmed subaxial cervical fracture and dislocation with facet locked by radiological examination, and the involved levels were C5-6. According to American Spinal Injury Association (ASIA) classification, the impairment scale was grade B. And the Subaxial Cervical Spine Injury and Severity Score (SLIC) were 9. The patient was restricted in sitting position with traction on a halo in extension to immobilize the head during the operation. A posterior laminectomy and pedicle screws insertion to the involved cervical spine was performed firstly. And then the anterior discectomy and strut graft were accomplished through an anterior cervical approach. The final fixation was finished by clamping the strut graft with pedicle screw system. Total blood loss was 600 ml and the total operating time was 150 min. The patient was followed up for 6 months. The symptom of neck pain improved distinctly and no evidence about implant failure was noted. Neurological status improvement was confirmed and the ASIA scale was improved to grade C. We believed that the simultaneously combined anterior-posterior approach in sitting position was safe and more advantageous for appropriate cases. PMID:26790982

    Full Text Available Cervical spondylosis is a progressive, chronic and insidious degenerative disease, which origins from the cervical intervertebral disc and then diffuses to surrounding bony and soft tissues. If the spine and nerve roots are involved due to degenerative changes, this is called as cervical spondylotic myeloradiculopathy (CSMR and it is the most frequent cause of myelopathy over age of 50. Cases with progressive character and functional neurological deficits and cases with a prolonged course refractory to conservative therapy shall be treated surgically. The aim of the surgical treatment is to relieve the pressure on the spinal cord and nerve roots, to preserve the proper anatomical alignment of the cervical vertebrae or to reestablish correct anatomical positioning if it is distorted and lastly to increase the life quality by relieving patients neurological signs and complaints. While achieving these goals, complications shall be avoided as much as possible. These goals can be accomplished by anterior or posterior surgical approaches to the cervical vertebrae. The style of the surgical approach can only be decided by a detailed evaluation of the patient's clinical and radiological features. The utmost aim of the surgical procedure, which is to achieve sufficient neurological decompression and to preserve/establish proper cervical vertebral alignment, can be provided best by anterior approaches. In our current study, the criteria to prefer anterior approach in surgical treatment of CSMR will be reviewed. [Cukurova Med J 2014; 39(4.000: 669-678

    Cervical nerve root compression caused by disco-osteophytic changes is classically operated by anterior transdiscal approach with disc replacement. If compression persists or recurs, reoperation via the same surgical route may be difficult, because of scar tissue and/or implants. An alternative approach may be necessary. We recommend the lateral cervical approach (retrojugular) as salvage operation in such cases. We report a patient with cervical nerve root compression operated by anterior tr...

    CONCLUSION: We achieved better cervical lordotic angles at the postoperative period by implanting one-level, two-level, three-level or four-level PEEK cage filled with demineralized bone matrix. Also, the causes of cervical root and or medulla spinalis impingement were different in group1 and 2. While extruded cervical disc impingement was the first pathology in group 1, osteophyte formation was the first pathology in group 2.

    Full Text Available Hematoma alone is the most common vascular complication reported after anterior cervical decompression and fusion (ACDF. We present this case to report the occurrence of postoperative cervical hematoma complicated by ipsilateral carotid thrombosis and aphasia after an uncomplicated C4–6 ACDF. This is a case of a 65-year-old woman who underwent revision fusions of the C4-5 and C6-7 levels complicated by postoperative cervical hematoma and carotid thrombosis. The patient's history, clinical examination, imaging findings, and treatment are reported. The revision fusions were performed and deemed routine. Approximately eight hours later 200 mL of blood was evacuated from a postoperative cervical hematoma. The patient became unresponsive and disoriented a few hours after evacuating the hematoma. Computed tomography and magnetic resonance imaging of the brain were normal, but magnetic resonance angiography demonstrated total occlusion of the left carotid artery. Thrombectomy was performed and the patient was discharged without residual deficits. At the latest followup she is fully functional and asymptomatic in her neck. We suggest, after evacuating a cervical hematoma, an evaluation of the carotids be made with MRA or cerebral angiography, as this may demonstrate a clot before the patient develops symptoms.

    This study reports 7 cases of cervical Pott's disease, gathered during 6 years in the department of neuro-surgery of Ibn Rochd U.H.C. 4 females and 3 males, aged between 9 and 52 years were included. All the patients complained of cervicobrachial pain and weakness of the limbs. Clinical features were: deterioration of general status, rachidian syndrome and neurological impairement with motor and sensitive deficit. Radiological analysis found a destructive and extensive lesion, cervical kyphosis from 10 degrees to 60 degrees, retropharyngeal abscess and intraspinal canal extension of infection. Diagnosis was confirmed by histological study in all cases. In addition to antituberculous therapy and preoperative cervical traction in 4 cases, all the patients had spinal fusion using an anterior approach. Post operative immobilization in a cervical collar varied from 9 to 12 months. All 7 patients had full neurological recovery, 6 patients had an excellent bony fusion and cervical kyphosis was corrected. For the remaining patient, the bone graft was mobilized without neurological disorders. This study confirms anterior arthrodesis efficiency. This procedure in conjunction with preoperative traction, allowed stabilization of the spine and healing of vertebral lesions with excellent kyphosis correction. PMID:9452797

    A pharyngeal diverticulum is a rare complication of an anterior cervical discectomy and fusion (ACDF). We present a case of a pharyngeal diverticulum after an ACDF, which was misdiagnosed as a typical Zenker diverticulum. A 54-year-old woman presented with dysphagia and a sense of irritation in the neck following C5 through C7 cervical fusion 3 years prior. The patient underwent open surgery to resect the diverticulum with concurrent cricopharyngeal myotomy. An ACDF-related diverticulum is difficult to distinguish from a typical Zenker diverticulum.

    Full Text Available OBJECTIVE: To estimate the effectiveness of anterior cervical discectomy with arthroplasty (ACDA compared to anterior cervical discectomy with fusion (ACDF for patient-important outcomes for single-level cervical spondylosis. DATA SOURCES: Electronic databases (MEDLINE, EMBASE, Cochrane Register for Randomized Controlled Trials, BIOSIS and LILACS, archives of spine meetings and bibliographies of relevant articles. STUDY SELECTION: We included RCTs of ACDF versus ACDA in adult patients with single-level cervical spondylosis reporting at least one of the following outcomes: functionality, neurological success, neck pain, arm pain, quality of life, surgery for adjacent level degeneration (ALD, reoperation and dysphonia/dysphagia. We used no language restrictions. We performed title and abstract screening and full text screening independently and in duplicate. DATA SYNTHESIS: We used random-effects model to pool data using mean difference (MD for continuous outcomes and relative risk (RR for dichotomous outcomes. We used GRADE to evaluate the quality of evidence for each outcome. RESULTS: Of 2804 citations, 9 articles reporting on 9 trials (1778 participants were eligible. ACDA is associated with a clinically significant lower incidence of neurologic failure (RR = 0.53, 95% CI = 0.37-0.75, p = 0.0004 and improvement in the Neck pain visual analogue scale (VAS (MD = 6.56, 95% CI = 3.22-9.90, p = 0.0001; Minimal clinically important difference (MCID = 2.5. ACDA is associated with a statistically but not clinically significant improvement in Arm pain VAS and SF-36 physical component summary. ACDA is associated with non-statistically significant higher improvement in the Neck Disability Index Score and lower incidence of ALD requiring surgery, reoperation, and dysphagia/dysphonia. CONCLUSIONS: There is no strong evidence to support the routine use of ACDA over ACDF in single-level cervical spondylosis. Current trials lack long-term data required to

    Abstract Background Titanium (TTN) cages have a higher modulus of elasticity when compared with polyetheretherketone (PEEK) cages. This suggests that TTN-cages could show more frequent cage subsidence after anterior cervical discectomy and fusion (ACDF) and therefore might lead to a higher loss of correction. We compared the long term results of stand-alone PEEK- and TTN-cages in a comparable patient collective that was operated under identical operative settings. Methods From 2002 to 2007 15...

    Full Text Available Aim: The aim of this study was to clinically and radiologically evaluate the efficacy of anterior cervical discectomy and fusion (ACDF in the treatment of adjacent level degeneration. Methods: We retrospectively evaluated 89 patients (55 females, 34 males who underwent ACDF. Adjacent segment degeneration findings were evaluated by investigating new osteophyte formation, growth of existing osteophytes, ossification of the anterior longitudinal ligament, presence of intervertebral disc space narrowing, sagittal alignment and range of motion (ROM using serial radiographs and magnetic resonance imaging. Results: The mean age of the 89 patients was 41.3 (24-76 years. The mean follow-up duration was 34.3 (12-64 months. Radiographic evidence of adjacent segment degeneration was observed in 12 patients (13.4%. Nine (75% patients had new complaints. Of the patients who had degenerative changes, 7 were (58% were male, 5 (42% were female; the mean age was 46 (30- 62 years. It was observed that the level of fusion and the number of fusion did not increase the adjacent segment degeneration. All of 12 patients were observed to have a non lordotic cervical spine and increased ROM. Conclusion: Development of degeneration at the level adjacent to region anterior cervical discectomy and fusion performed is higher compared to non-adjacent levels. The level of fusion and the number of fusion levels have no effect on the development of degeneration. (The Medical Bulletin of Haseki 2015; 53:120-3

    Full Text Available Background: The optimal approach to provide satisfactory decompression and minimize complications for ossification of the posterior longitudinal ligament (OPLL involving multiple levels (3 levels or more remains controversial. The purpose of this study was to compare the results of two surgical approaches for cervical OPLL involving multiple levels; anterior direct decompression and fixation, and posterior indirect decompression and fixation. We present a retrospective review of 56 cases followed at a single Institution. Materials and Methods: We compared patients of multiple levels cervical OPLL that were treated at a single institution either with anterior direct decompression and fixation or with posterior indirect decompression and fixation. The clinical records of the patients with a minimum duration of follow-up of 2 years were reviewed. The associated complications were recorded. Results: Fifty-six patients constitute the clinical material. 26 cases were treated by anterior corpectomy and fixation and 30 cases received posterior laminectomy and fixation. The two populations were similar. It was found that both anterior and posterior decompression and fixation can achieve satisfactory outcomes, and posterior surgery was accomplished in a shorter period of time with lesser blood loss. Although patients had comparable preoperative Japanese Orthopaedics Association (JOA scores, those with a canal occupancy by OPLL more than 50% and managed anteriorly had better outcomes. However, for those with more severe stenosis, anterior approach was more difficult and associated with higher risks and complications. Despite its limitations in patients with high occupancy OPLLs, through the multiple level laminectomy, posterior fixation can achieve effective decompression, maintaining or restoring stability of the cervical spine, and thereby improving neural outcome and preventing the progression of OPLL. Conclusions: The posterior indirect decompression

    Full Text Available Background: Subaxial cervical spine dislocations are common and often present with neurological deficit. Posterior spinal fusion has been the gold standard in the past. Pain and neck stiffness are often the presenting features and may be due to failure of fixation and extension of fusion mass. Anterior spinal fusion which is relatively atraumatic is thus favored using autogenous grafts and cages with anterior plate fixation. We evaluated fresh frozen fibular allografts and anterior plate fixation for anterior fusion in cervical trauma. Materials and Methods: Sixty consecutive patients with single-level dislocations or fracture dislocations of the subaxial cervical spine were recruited in this prospective study following a motor vehicle accident. There were 38 males and 22 females. The mean age at presentation was 34 years (range 19-67 years. The levels involved were C5/6 ( n = 36, C4/5 ( n = 15, C6/7 ( n = 7 and C3/4 ( n = 2. There were 38 unifacet dislocations with nine posterior element fractures and 22 were bifacet dislocations. Twenty-two patients had neurological deficit. Co-morbidities included hypertension ( n = 6, non-insulin-dependent diabetes mellitus ( n = 2 and asthma ( n = 1. All patients were initially managed on skull traction. Following reduction further imaging included Computerized Tomography and Magnetic Resonance Imaging. Patients underwent anterior surgery (discectomy, fibular allograft and plating. All patients were immobilized in a Philadelphia collar for eight weeks (range 7-12 weeks. Eight patients were lost to follow-up within a year. Follow-up clinical and radiological examinations were performed six-weekly for three months and subsequently at three-monthly intervals for 12 months. Pain was analyzed using the visual analogue scale (VAS. The mean follow-up was 19 months (range 14-39 months. Results: Eight lost to followup, hence 52 patients were considered for final evaluation.

    Full Text Available BACKGROUND: Results showed good clinical outcomes of anterior corpectomy and fusion (ACCF for patients with cervical spondylotic myelopathy (CSM during a short term follow-up; however, studies assessing long term results are relatively scarce. In this study we intended to assess the long term clinical and radiographic outcomes, find out the factors that may affect the long term clinical outcome and evaluate the incidence of adjacent segment disease (ASD. METHODS: This is a retrospective study of 145 consecutive CSM patients on ACCF treatment with a minimum follow-up of 5 years. Clinical data were collected from medical and operative records. Patients were evaluated by using the Japanese Orthopedic Association (JOA scoring system preoperatively and during the follow-up. X-rays results of cervical spine were obtained from all patients. Correlations between the long term clinical outcome and various factors were also analyzed. FINDINGS: Ninety-three males and fifty-two females completed the follow-up. The mean age at operation was 51.0 years, and the mean follow-up period was 102.1 months. Both postoperative sagittal segmental alignment (SSA and the sagittal alignment of the whole cervical spine (SACS increased significantly in terms of cervical lordosis. The mean increase of JOA was 3.8 ± 1.3 postoperatively, and the overall recovery rate was 62.5%. Logistic regression analysis showed that preoperative duration of symptoms >12 months, high-intensity signal in spinal cord and preoperative JOA score ≤ 9 were important predictors of the fair recovery rate (≤ 50%. Repeated surgery due to ASD was performed in 7 (4.8% cases. CONCLUSIONS: ACCF with anterior plate fixation is a reliable and effective method for treating CSM in terms of JOA score and the recovery rate. The correction of cervical alignment and the repeated surgery rate for ASD are also considered to be satisfactory.

  18. Cervical total disc replacement is superior to anterior cervical decompression and fusion: a meta-analysis of prospective randomized controlled trials.

    Directory of Open Access Journals (Sweden)

    Yujie Zhang

    Full Text Available Despite being considered the standard surgical procedure for symptomatic cervical disc disease, anterior cervical decompression and fusion invariably accelerates adjacent segment degeneration. Cervical total disc replacement is a motion-preserving procedure developed as a substitute to fusion. Whether cervical total disc replacement is superior to fusion remains unclear.We comprehensively searched PubMed, EMBASE, Medline, and the Cochrane Library in accordance with the inclusion criteria to identify possible studies. The retrieved results were last updated on December 12, 2014. We classified the studies as short-term and midterm follow-up.Nineteen randomized controlled trials involving 4516 cases were identified. Compared with anterior cervical decompression and fusion, cervical total disc replacement had better functional outcomes (neck disability index [NDI], NDI success, neurological success, neck pain scores reported on a numerical rating scale [NRS], visual analog scales scores and overall success, greater segmental motion at the index level, fewer adverse events and fewer secondary surgical procedures at the index and adjacent levels in short-term follow-up (P 0.05.Cervical total disc replacement presented favorable functional outcomes, fewer adverse events, and fewer secondary surgical procedures. The efficacy and safety of cervical total disc replacement are superior to those of fusion. Longer-term, multicenter studies are required for a better evaluation of the long-term efficacy and safety of the two procedures.

    Objective: To analyze and compare the clinical efficacy of anterior and posterior decompression in the treatment of multi-segmental cervical spondylotic myelopathy (MCSM), providing certain guidance for the clinical treatment. Methods:A total of 72 patients with MCSM who were admitted in our hospital from September, 2012 to October, 2014 were included in the study and divided into the anterior group (n=37) and the posterior group (n=35) according to different surgical methods. The patients in the anterior group were given anterior cervical discectomy fusion (ACDF) and anterior cervical corpectomy fusion (ACCF), while the patients in the posterior group were given laminoplasty (LP). The general materials, surgical materials, and postoperative functional recovery in the two groups were compared. Results:The comparison of gender, age, course, preoperative JOA score, follow-up time, and affected segment between the two groups was not statistically significant. The operation time in the anterior group was significantly longer than that in the posterior group, but the intraoperative amount of bleeding was significantly less than that in the posterior group. The postoperative spinal cord function in the two groups was significantly improved when compared with before operation;moreover, the improved degree in the anterior group was more obvious. The postoperative cervical physiological curvature in the anterior group was significantly increased, but in the posterior group was significantly reduced. The comparison of the occurrence rate of postoperative complications between the two groups was not statistically significant. Conclusions:The anterior and posterior surgeries in the treatment of MCSM can significantly improve the postoperative spinal cord function, among which the anterior surgery can effectively recover the cervical physiological curvature. It is recommended that an appropriate surgical method should be reasonably selected by comprehensively considering the

    Full Text Available Aims : To determine the surgical approach in patients with multisegmental (four or more segments OPLL of the cervical spine. Methods and Materials : Data of 27 patients who had undergone either an anterior (corpectomy with excision of OPLL and interbody fusion=14 patients or posterior approach (laminectomy=12, laminoplasty=1 patient for the multisegmental cervical OPLL was analyzed retrospectively. The patients in each group were statistically similar in respect to preoperative factors such as age, duration of symptoms, preoperative modified Japanese orthopedic association score, OPLL thickness, effective canal diameter, and antero-posterior cord compression ratio. The clinical outcome was assessed by the Harsh grading system and recovery rate was assessed by Hirabayashi method. Results : There was no statistical difference in the outcome, and recovery rate. Nine patients developed complications after anterior approach in contrast to one after posterior approach. Conclusions : In patients with multisegmental cervical OPLL, there was no significant difference in the short-term recovery rate and outcome between two groups. The immediate postoperative complications were less in patients who had undergone posterior approach. From our analysis, it appears that the posterior approach is probably the preferred method of treatment in a multisegmental OPLL in absence of preoperative kyphosis.

    2002-01-01

    Full Text Available Serial roentgenograms of 40 patients who had 70 cervical intervertebral spaces grafted with ethylene oxide sterilized cadaver bone and 28 patients who received 44 iliac crest auto grafts for anterior cervical spine fusion, were studied. The radiological evaluation was made on the basis of settlement of intervertebral spaces, fusion rate, delayed union, non-union, graft collapse and extrusion of the graft. Indigenous methodologies were designed for the assessment of settlement of grafted intervertebral spaces in percentage. Disc space settlement was more common in autografts (93% cases than in allografts (80% cases. The average percentage of settlement of intervertebral disc space (S% was 22 in autografts and 28 in allografts during the first four months. By the end of eight months, allograft disc spaces settle more. No significant difference was noted in fusion rate at the end of one year viz. allografts (90% cases and autografts (93% cases. Autograft and allograft (ethylene oxide sterilized cadaver bone are equally useful in anterior cervical spine fusions.

The excellent and good rates of nerve function amelioration were 93.0% and 90.7% at 3 and 12 months postoperation, respectively, which was not significantly different. Twenty-seven cases exhibited a significantly reduced protrusion area (P <0.01) at 3 months postoperation. No serious side effects were noted.To our knowledge, this is the first study to demonstrate that the use of radiofrequency combined with low-dose collagenase injection into the disc interior via an anterior cervical approach is effective and safe for the treatment of cervical intervertebral disc herniation.

    This study aimed to determine the therapeutic effect of radiofrequency combined with low-dose collagenase injected into the disc interior via an anterior cervical approach for cervical intervertebral disc herniation.Forty-three patients (26-62-year old; male/female ratio: 31/12) with cervical intervertebral disc herniation received radiofrequency combined with 60 to 100 U of collagenase, injected via an anterior cervical approach. The degree of nerve function was assessed using the current Japanese Orthopaedic Association (JOA) scoring system at 3 and 12 months postoperation. A visual analogue scale (VAS) was used to evaluate the degree of pain preoperation and 7 days postoperation. The preoperative and 3 month postoperative protrusion areas were measured and compared via magnetic resonance imaging (MRI) and picture archiving and communication systems (PACS).Compared with the preoperative pain scores, the 7-day postoperative pain was significantly reduced (P <0.01).

    OBJECTIVE Esophageal perforation is a rare but well-known complication of anterior cervical spine surgery. The authors performed a systematic review of the literature to evaluate symptomatology, direct causes, repair methods, and associated complications of esophageal injury. METHODS A PubMed search that adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines included relevant clinical studies and case reports (articles written in the English language that included humans as subjects) that reported patients who underwent anterior spinal surgery and sustained some form of esophageal perforation. Available data on clinical presentation, the surgical procedure performed, outcome measures, and other individual variables were abstracted from 1980 through 2015. RESULTS The PubMed search yielded 65 articles with 153 patients (mean age 44.7 years; range 14-85 years) who underwent anterior spinal surgery and sustained esophageal perforation, either during surgery or in a delayed fashion. The most common indications for initial anterior cervical spine surgery in these cases were vertebral fracture/dislocation (n = 77), spondylotic myelopathy (n = 15), and nucleus pulposus herniation (n = 10). The most commonly involved spinal levels were C5-6 (n = 51) and C6-7 (n = 39). The most common presenting symptoms included dysphagia (n =63), fever (n = 24), neck swelling (n = 23), and wound leakage (n = 18). The etiology of esophageal perforation included hardware failure (n = 31), hardware erosion (n = 23), and intraoperative injury (n = 14). The imaging modalities used to identify the esophageal perforations included modified contrast dye swallow studies, CT, endoscopy, plain radiography, and MRI. Esophageal repair was most commonly achieved using a modified muscle flap, as well as with primary closure. Outcomes measured in the literature were often defined by the time to oral intake following esophageal repair. Complications included

    Full Text Available Abstract Background Spinal surgery is increasingly being done in the outpatient setting. We reviewed our experience with inpatient and outpatient single-level anterior cervical discectomy and fusion with plating (ACDF+P. Methods All patients undergoing single-level anterior cervical discectomy and fusion with plating between August 2005 and May 2007 by two surgeons (RPB or JAF were retrospectively reviewed. All patients underwent anterior cervical microdiscectomy, arthrodesis using structural allograft, and titanium plating. A planned change from doing ACDF+P on an inpatient basis to doing ACDF+P on an outpatient basis was instituted at the midpoint of the study. There were no other changes in technique, patient selection, instrumentation, facility, or other factors. All procedures were done in full-service hospitals accommodating outpatient and inpatient care. Results 64 patients underwent ACDF+P as inpatients, while 45 underwent ACDF+P as outpatients. When outpatient surgery was planned, 17 patients were treated as inpatients due to medical comorbidities (14, older age (1, and patient preference (2. At a mean follow-up of 62.4 days, 90 patients had an excellent outcome, 19 patients had a good outcome, and no patients had a fair or poor outcome. There was no significant difference in outcome between inpatients and outpatients. There were 4 complications, all occurring in inpatients: a hematoma one week post-operatively requiring drainage, a cerebrospinal fluid leak treated with lumbar drainage, syncope of unknown etiology, and moderate dysphagia. Conclusion In this series, outpatient ACDF+P was safe and was not associated with a significant difference in outcome compared with inpatient ACDF+P.

    Full Text Available Background: To investigate the association between single nucleotide polymorphisms (SNPs of bone morphogenic proteins-4 (BMP-4 gene and the susceptibility of cervical spondylotic myelopathy (CSM and its outcome after surgical treatment. Method: A total of 499 patients with CSM and 602 healthy volunteers were recruited. 425 CSM patients received anterior cervical corpectomy and fusion (ACF and were follow-up until 12 months. The SNPs of BMP-4 were determined. Results: For 6007C > T polymorphism, the cases had a significant lower prevalence of TT genotype than controls. With the CC genotype as reference, the TT genotype carriages significantly influence the CSM risk. The T allele carriage represented a higher risk for CSM as well. The TT of 6007C>T polymorphisms is also associated with higher chance to gain improvement from ACF surgery. The T allele carriage of 6007C>T had markedly higher chance to have a better post-operative outcome compared with C allele carriage. The genotype and allele distributions of -5826G>A polymorphism did not show positive association with risk and outcome of CSM in this study. Conclusion: BMP-4 genetic polymorphisms may be used as a molecular marker for the CSM susceptibility and its postoperative outcome in those underwent surgical treatment.

    Background: Isolated cervical anterior spinal artery aneurysms are extremely rare. Subarachnoid hemorrhage (SAH) secondary to such lesions have been described only in six cases to the best of our knowledge. Case Description: We describe an unusual clinical picture of SAH due to rupture of anterior spinal artery aneurysm in a patient with previous normal angiogram. Due to the location of the aneurysm and clinical status of the patient, conservative management was proposed, and she was discharged to further follow-up. Monthly routine angiograms revealed resolution of the aneurysm 90 days after bleeding, which was highly suggestive of vascular dissection. Conclusion: We highlight the need to consider these aneurysms in the differential diagnosis of SAH, especially when occurring in the posterior fossa and when angiography findings are inconclusive.

    The purpose of this study was to compare the results of 2 surgical strategies for 4-level cervical spondylotic myelopathy: a hybrid procedure using anterior cervical diskectomy and fusion (ACDF) combined with segmental corpectomy versus posterior laminectomy and fixation. Between 2002 and 2010, fifty-one patients with consecutive 4-level cervical spondylotic myelopathy were treated surgically, with 27 patients undergoing the hybrid procedure and 24 undergoing posterior laminectomy and fixation. Radiologic data were compared between the 2 groups, including cervical curvature and cervical range of motion (ROM) in the sagittal plane. Pre- and postoperative neurological status was evaluated using the Japanese Orthopaedic Association (JOA) scoring system and the Nurick grading system. Mean ROM at last follow-up was not significantly different between the 2 groups (P>.05). In the hybrid group, mean JOA score and Nurick grade improved from 9.6±1.4 and 2.74±0.45 respectively, preoperatively, to 13.9±1.3 and 0.86±0.38 respectively, postoperatively. In the fixation group, mean JOA score and Nurick grade improved from 9.4±1.2 and 2.81±0.42 respectively, preoperatively, to 13.1±1.5 and 1.32±0.36 respectively, postoperatively. The JOA scores and Nurick grades at last follow-up were significantly different between the 2 groups (Pcervical kyphosis, preoperative JOA score and Nurick grade were not significantly different between the 2 groups (P>.05); however, JOA scores and Nurick grades at last follow-up showed better improvement in the hybrid group than in the fixation group (Pcervical lordosis, the preoperative and last follow-up JOA score and Nurick grade were not significantly different between the 2 groups (P>.05).

    Full Text Available Abstract Background Patients with cervical radicular syndrome due to disc herniation refractory to conservative treatment are offered surgical treatment. Anterior cervical discectomy is the standard procedure, often in combination with interbody fusion. Accelerated adjacent disc degeneration is a known entity on the long term. Recently, cervical disc prostheses are developed to maintain motion and possibly reduce the incidence of adjacent disc degeneration. A comparative cost-effectiveness study focused on adjacent segment degeneration and functional outcome has not been performed yet. We present the design of the NECK trial, a randomised study on cost-effectiveness of anterior cervical discectomy with or without interbody fusion and arthroplasty in patients with cervical disc herniation. Methods/Design Patients (age 18-65 years presenting with radicular signs due to single level cervical disc herniation lasting more than 8 weeks are included. Patients will be randomised into 3 groups: anterior discectomy only, anterior discectomy with interbody fusion, and anterior discectomy with disc prosthesis. The primary outcome measure is symptomatic adjacent disc degeneration at 2 and 5 years after surgery. Other outcome parameters will be the Neck Disability Index, perceived recovery, arm and neck pain, complications, re-operations, quality of life, job satisfaction, anxiety and depression assessment, medical consumption, absenteeism, and costs. The study is a randomised prospective multicenter trial, in which 3 surgical techniques are compared in a parallel group design. Patients and research nurses will be kept blinded of the allocated treatment for 2 years. The follow-up period is 5 years. Discussion Currently, anterior cervical discectomy with fusion is the golden standard in the surgical treatment of cervical disc herniation. Whether additional interbody fusion or disc prothesis is necessary and cost-effective will be determined by this trial

    Eighty-two patients operated on in our Department between 1989 and 1995 with an anterior cervical approach for soft and hard cervical disc herniations and cervical stenosis were included in this study. In 41 cases a heterologous intersomatic bovine graft (Surgibone) was used. Another 41 patients underwent surgery with a biocompatible osteoconductive polymer (BOP) as intervertebral graft. Both groups were retrospectively reviewed and compared with the objectives of evaluating the biodynamic behaviour of the grafts in the intersomatic space, the complications which appeared (specially those related to the grafts), the bone fusion rate achieved and the clinical outcome of the patients. The results of our study show that the BOP group presented a higher tendency to intersomatic space collapse 6 months after discectomy. There were no differences in the general surgical complications between both groups, but those related directly to the graft were significantly higher in the BOP group. The vast majority of the graft complications recorded had no clinical correlation. Without a strict radiological follow-up such complications would never have been discovered. Bone fusion in the BOP group was significantly slower and worse. Finally, the clinical outcome in both groups did not show any significant difference. PMID:10398991

    To discuss the pathological characteristics of cervical spinal fracture complicating ankylosing spondyli-tis-(AS) and the effect of combined anterior and posterior operation. Methods: Eighteen AS patients with traumatic cervical fracture-dislocation were treated operatively from January 2000 to January 2006. The symptom duration of AS was 14.5 years on average. Three cases had undergone osteotomy in lumbar spine. There were 4 cases of Grade A, 3 cases of Grade B, 9 cases of Grade C and 2 cases of Grade D accord-ing to Frankel's score. There were 15 cases of Grade Ⅲ dislocation and 3 cases of Grade Ⅱ. All patients underwent surgical procedures by combined anterior and posterior approach.Results: There were 4 anterior-posterior procedures, 8 anterior-posterior-anterior procedures and 6 posterior-an-terior procedures. Seven patients had one stage operation and 11 cases underwent two stage surgeries. There was certain extent of neorological improvement in 14 incomplete paraplegic patients, but no improvement in 4 complete paraplegic patients. The follow-up period was 21.2 months on average and the time for bone fusion was 3.6 months. There were 4 complications during operation and a long-term complication in follow-up. Conclusions: The study suggests that anterior com-bined with posterior approach makes the spine stable and relieves the pressure immediately. It is a reasonable surgical strategy for treatment of cervical spinal fracture-dislocation with AS.

    Full Text Available Introduction: Although perforation of the esophagus, in the anterior cervical spine fixation, is well established, cases with delayed onset, especially cases that present pseudodiverticulum, are not common. In addition, management of the perforation in this situation is debated.  Case Report:   Delayed esophageal pseudodiverticulum was managed in two patients with a history of anterior spine fixation. Patients were operated on, the loose plate and screws were extracted, the wall of the diverticulum was excised, the perforation on the nasogastric tube was suboptimally repaired, and a closed suction drain was placed there. The NGT was removed on the 7th day and barium swallow demonstrated no leakage at the operation site; therefore, oral feeding was started without any problem.  Conclusion:  In cases with delayed perforation, fistula, or diverticulum removal of anterior fixation instruments, gentle repair of the esophageal wall without persistence on definitive and optimal perforation closure, wide local drainage, early enteral nutrition via NGT, and antibiotic prescription is suggested.

    Full Text Available We report a patient with congenital anomaly of cervical spine, who presented with clinical features suggestive of cervical compressive spondylotic myelopathy. He underwent C3 median corpectomy, graft placement, and stabilization from C2 to C4 vertebral bodies. Postoperative period was uneventful and he improved in his symptoms. Eight years later, he presented with a difficulty in swallowing and occasional regurgitation of feeds of 2 months duration and oral extrusion of screw while having food. On oral examination, there was a defect in the posterior pharyngeal wall through which the upper end of plate with intact self-locking screw and socket of missed fixation screw was seen. This was confirmed on X-ray cervical spine. He underwent removal of the plate system and was fed through nasogastric tube and managed with appropriate antibiotics. This case is presented to report a very rare complication of anterior cervical plate fixation in the form of very late-onset dislodgement, migration of anterior cervical plate, and oral extrusion of screw through perforated posterior pharyngeal wall.

    Full Text Available Abstract Introduction There have been few reports of patients with bilateral cervical facet dislocations that remain untreated for eight weeks or more. We report the case of a 76-year-old man with an old bilateral cervical facet joint dislocation fracture that was treated by posterior-anterior reduction and fixation. Case presentation A 76-year-old Asian man was involved in a road traffic accident. He presented with neck pain and arm pain on his right side, but motor weakness and paralysis were not observed. He was treated conservatively; however, instability and spondylolisthesis at the C5 to C6 joint increased eight weeks after the injury. We performed a posterior-anterior reduction and fixation. After surgery, bony union was achieved, and his neck pain and arm pain disappeared. Conclusion We recommend reduction and fixation surgery if a patient has an old bilateral facet joint dislocation fracture in the cervical spine.

    Full Text Available Intervertebral fusion through an anterior approach with polymethylacrylate is a wellestablished neurosurgical technique in the treatment of cervical spine degeneration. However, questions still remain concerning the post-surgical outcome. Factors influencing surgical outcome that could help to predict which patients need further post-surgical treatment and what to expect after surgery are the subject of numerous studies. In the present study, we retrospectively collected data from patients who had undergone intervertebral fusion and defined which pre-operative factors could influence the surgical outcome. Between 1993 and 1997, 379 patients were surgically treated with the ventral fusion technique in our hospital. In 2006, we sent a questionnaire to the patients and 164 responses were received. We identified pre-operative presence of severe pain, hypesthesia, palsy and gait disturbance as negative predictive factors, whereas age, body mass index, pre-operative physical strain and the cervical segment involved did not seem to influence prognosis. In conclusion, identifying preoperative factors which influence prognosis after intervetebral fusion will help predict postoperative outcome.

  19. Use of autologous bone graft in anterior cervical decompression: morbidity & quality of life analysis.

    Heneghan, Helen M

    2009-01-01

    BACKGROUND: Autologous iliac crest graft has long been the gold standard graft material used in cervical fusion. However its harvest has significant associated morbidity, including protracted postoperative pain scores at the harvest site. Thus its continued practice warrants scrutiny, particularly now that alternatives are available. Our aims were to assess incidence and nature of complications associated with iliac crest harvest when performed in the setting of Anterior Cervical Decompression (ACD). Also, to perform a comparative analysis of patient satisfaction and quality of life scores after ACD surgeries, when performed with and without iliac graft harvest. METHODS: All patients who underwent consecutive ACD procedures, with and without the use of autologous iliac crest graft, over a 48 month period were included (n = 53). Patients were assessed clinically at a minimum of 12 months postoperatively and administered 2 validated quality of life questionnaires: the SF-36 and Cervical Spine Outcomes Questionnaires (Response rate 96%). Primary composite endpoints included incidence of bone graft donor site morbidity, pain scores, operative duration, and quality of life scores. RESULTS: Patients who underwent iliac graft harvest experienced significant peri-operative donor site specific morbidity, including a high incidence of pain at the iliac crest (90%), iliac wound infection (7%), a jejunal perforation, and longer operative duration (285 minutes vs. 238 minutes, p = 0.026). Longer term follow-up demonstrated protracted postoperative pain at the harvest site and significantly lower mental health scores on both quality of life instruments, for those patients who underwent autologous graft harvest CONCLUSION: ACD with iliac crest graft harvest is associated with significant iliac crest donor site morbidity and lower quality of life at greater than 12 months post operatively. This is now avoidable by using alternatives to autologous bone without compromising clinical

    Full Text Available OBJECT: The concept of minimum clinically important difference (MCID has been used to measure the threshold by which the effect of a specific treatment can be considered clinically meaningful. MCID has previously been studied in surgical patients, however few studies have assessed its role in spinal surgery. The goal of this study was to assess the role of MCID in patients undergoing anterior cervical discectomy and fusion (ACDF for cervical spondylotic myelopathy (CSM. METHODS: Data was collected on 30 patients who underwent ACDF for CSM between 2007 and 2012. Preoperative and 1-year postoperative Neck Disability Index (NDI, Visual-Analog Scale (VAS, and Short Form-36 (SF-36 Physical (PCS and Mental (MCS Component Summary PRO scores were collected. Five distribution- and anchor-based approaches were used to calculate MCID threshold values average change, change difference, receiver operating characteristic curve (ROC, minimum detectable change (MDC and standard error of measurement (SEM. The Health Transition Item of the SF-36 (HTI was used as an external anchor. RESULTS: Patients had a significant improvement in all mean physical PRO scores postoperatively (p<0.01 NDI (29.24 to 14.82, VAS (5.06 to 1.72, and PCS (36.98 to 44.22. The five MCID approaches yielded a range of values for each PRO: 2.00-8.78 for PCS, 2.06-5.73 for MCS, 4.83-13.39 for NDI, and 0.36-3.11 for VAS. PCS was the most representative PRO measure, presenting the greatest area under the ROC curve (0.94. MDC values were not affected by the choice of anchor and their threshold of improvement was statistically greater than the chance of error from unimproved patients. CONCLUSION: SF-36 PCS was the most representative PRO measure. MDC appears to be the most appropriate MCID method. When MDC was applied together with HTI anchor, the MCID thresholds were: 13.39 for NDI, 3.11 for VAS, 5.56 for PCS and 5.73 for MCS.

    Full Text Available Anterior cervical discectomy and fusion is a commonly performed procedure for prolapse of cervical intervertebral disc. It involves retraction of soft tissue of neck for adequate exposure of anterior spinal canal. Increased cuff pressure with retractor application may affect the postoperative vocal cord function. Cuff pressures of tracheal tube were measured continuously in 37 patients using air-filled pressure transducer connected to the pilot balloon. Changes of pressure from baseline values were noted after application of cervical retractor. At the end of procedure, vocal cord movement was observed using fibreoptic bronchoscope. Significant increase in cuff pressure (168% of baseline values and airway pressure of tracheal tube during cervical retraction was observed. The vocal cord function was assessed using fibreoptic laryngoscope. One patient developed right vocal cord palsy (2.7% and two patients had postoperative hoarseness of voice (5.4%. All these complications improved over a period of time. It is suggested that the cuff of tracheal tube should be inflated to achieve ′just seal′, with adequate cuff pressure monitoring. Intermittent release of cervical retraction may help to prevent laryngeal morbidities.

    Different types of cages have recently become available for reconstruction following anterior cervical corpectomy. We review the results using titanium mesh cages (TMC) and stackable CFRP (carbon fibre reinforced polymer) cages. Forty-two patients who underwent anterior cervical corpectomy between November 2001 and September 2008 were retrospectively reviewed. Pathologies included cervical spondylotic myelopathy (CSM), cervical radiculopathy, OPLL (ossified posterior longitudinal ligament), metastasis/primary bone tumour, rheumatoid arthritis and deformity correction. All patients were evaluated clinically and radiologically. Outcome was assessed on the basis of the Odom's criteria, neck disability index (NDI) and myelopathy disability index (MDI). Mean age was 60 years and mean follow-up was 1½ years. Majority of the patients had single-level corpectomy. Twenty-three patients had TMC cages while 19 patients had CFRP cages. The mean subsidence noted with TMC cage was 1.91 mm, while with the stackable CFRP cage it was 0.5 mm. This difference was statistically significant (p 0.05) or between subsidence and post-operative sagittal alignment (p > 0.05) in either of the groups. Three patients had significant subsidence (> 3 mm), one of whom was symptomatic. There were no hardware-related complications. On the basis of the Odom's criterion, 9 patients (21.4%) had an excellent outcome, 14 patients (33.3%) had a good outcome, 9 patients (21.4%) had a fair outcome and 5 patients (11.9%) had a poor outcome, i.e. symptoms and signs unchanged or exacerbated. Mean post-operative NDI was 26.27% and mean post-operative MDI was 19.31%. Fusion was noted in all 42 cases. Both TMC and stackable CFRP cages provide solid anterior column reconstruction with good outcome following anterior cervical corpectomy. However, more subsidence is noted with TMC cages though this might not significantly alter the clinical outcome unless the subsidence is significant (>3 mm).

    Objectives: To explore the clinical features of traumatic atlantoaxial instability combined with subaxial cervical spinal cord injury (CSCI), and to analyze the feasibility, indication and therapeutic effects of anterior-posterior approach in such cases.Methods: From March 2004 to September 2009, 16cases with this trauma were admitted and surgically treated in our department. Before surgery, skull traction was performed. Posterior atlantoaxial pedicle screw internal fixation and bone graft fusion were conducted to manage traumatic atlantoaxial instability. As for subaxial CSCI, anterior cervical corpectomy or discectomy decompression, bone grafting and internal fixation with steel plates were applied.Results: All operations were successful. The average operation time was 3 hours and operative blood loss 400 ml. Satisfactory reduction of both the upper and lower cervical spine and complete decompression were achieved. All patients were followed up for 12 to 36 months. Their clinical symptoms were improved by various levels. The Japanese Orthopaedic Association (JOA) scores ranged from 10to 16 one year postoperatively, 13.95±2.06 on average (improvement rate= 70.10% ). X-rays, spiral CT and MRI confirmed normal cervical alignments, complete decompression and fine implants' position. There was no breakage or loosening of screws, nor exodus of titanium mesh or implanted bone blocks. The grafted bone achieved fusion 3-6 months postoperatively and no atlantoaxial instability was observed.Conclusions: Traumatic atlantoaxial instability may combine with subaxial CSCI, misdiagnosis of which should be especially alerted and avoided. For severe cases, one stage anterior-posterior approach to decompress the upper and lower cervical spine, together with reposition, bone grafting and fusion, as well as internal fixation can immediately restore the normal alignments and stability of the cervical spine and effectively improve the spinal nervous function, thus being an ideal

    Bioresorbable plates have recently been used with anterior cervical discectomy and fusion (ACDF). Compared with metallic plates, bioresorbable plates provide segmental stabilization with minimal imaging artifact, eventual resorption, and increased load sharing. The objectives of the present study were to determine whether a bioresorbable plate can withstand simulated physiologic static and cyclic loading, to compare the reduction in flexibility provided by bioresorbable and titanium plates, and to quantify load sharing between the plate and spine with graft. Sixteen human cervical motion segments were tested to +/-2.5 Nm in flexion-extension, lateral bending, and axial rotation. Range of motion (ROM) was measured (1) in the intact state, (2) with ACDF without plating, (3) after addition of either a bioresorbable or titanium plate, and (4) after 500 cycles of combined flexion-extension and axial torsion. Load sharing was evaluated by applying the same fixed rotation both without and with the plate, and was calculated as the moment resisted by the uninstrumented ACDF expressed as a percentage of the plated ACDF state. No plate failures or graft migration occurred during testing. Compared with the uninstrumented ACDF, bioresorbable plates reduced mean ROM by 49% in flexion-extension and 25% in lateral bending, with very little change in torsion. Titanium plates reduced uninstrumented ACDF ROM by 69% in flexion-extension, 45% in lateral bending, and 27% in torsion. Differences between bioresorbable and titanium plates were significant in flexion-extension and lateral bending. Cyclic loading did not significantly change ROM for either plate. More moment was shared in lateral bending by the spine/graft with bioresorbable plates (78%) compared with titanium plating (63%). Bioresorbable plates contained an intervertebral graft, provided some stabilization, remained intact throughout the simulated immediate postoperative loading, and shared more load with the graft and

    Anterior cervical fusion (ACF) after discectomy and/or corpectomy is a common procedure with traditionally good patient outcomes. Though typically mild, postoperative dysphagia can result in significant patient morbidity. In this study, we examine the relationship between postoperative dysphagia and in-hospital outcomes, readmissions, and overall costs. The University HealthSystem Consortium (UHC) database was utilized to perform a retrospective cohort study of all adults who underwent a principal procedure of ACF of the anterior column (International Classification of Diseases, Ninth Revision [ICD-9] procedure code 81.02) between 2013 and 2015. Patients with a diagnosis of dysphagia (ICD-9 78720-78729) were compared to those without. Patient demographics, length of stay, in-hospital mortality, 30-day readmissions, and direct costs were recorded. A total of 49,300 patients who underwent ACF were identified. Mean age was 54.5years and 50.2% were male. Dysphagia was documented in 3,137 patients (6.4%) during their hospital stay. Patients with dysphagia had an average 2.1 comorbidities, while patients without dysphagia had 1.5 (p<0.01). Mean length of stay was 6.38days in patients with dysphagia, and 2.13days in those without (p<0.01). In-hospital mortality was 0.10% in patients without dysphagia, and 0.61% in those with dysphagia (p<0.01). Direct costs were $13,099 in patients without dysphagia, and $21,245 in those with dysphagia (p<0.01). Thirty-day readmission rate was 2.9% in patients without dysphagia, and 5.3% in those with dysphagia (p=0.01). In summary, dysphagia in patients who undergo ACF correlates with significantly increased length of stay, 30-day readmissions, and in-hospital mortality. Direct costs are similarly increased as a result.

    This study reports on a 70-year-old man with recurrent cervical myelopathy 20 years after anterior decompression and fusion of C4-7 using a free vascularised strut graft. The recurrent myelopathy was secondary to a kyphotic deformity of a fractured graft and residual ossification of the posterior longitudinal ligament with stenosis at C3/4. Intraoperative spinal cord-evoked potentials indicated that spinal cord traction secondary to progressive kyphosis of the cervical spine after the graft fracture was the cause. The patient underwent laminoplasty at C3 and laminectomy at C4 to decompress the stenosis at C3/4 as well as posterior cervical spinal fusion at C3-7 with pedicle screws and a lateral mass screw and a bone graft to prevent further progression of the kyphosis. At postoperative 18 months, the patient's Japanese Orthopaedic Association score had improved to 14 from 8, and he could walk without support. PMID:26321562

    To assess the long-term clinical and radiographic outcomes of anterior cervical corpectomy and fusion (ACCF) with a neotype nano-hydroxyapatite/polyamide 66 (n-HA/PA66) strut in the treatment of cervical spondylotic myelopathy (CSM). Fifty patients with CSM who underwent 1- or 2-level ACCF with n-HA/PA66 struts were retrospectively investigated. With a mean follow-up of 79.6 months, the overall mean JOA score, VAS and cervical alignment were improved significantly. At last follow-up, the fusion rate was 98%, and the subsidence rate of the n-HA/PA66 strut was 8%. The “radiolucent gap” at the interface between the n-HA/PA66 strut and the vertebra was further noted to evaluate the osteoconductivity and osseointegration of the strut, and the incidence of it was 62% at the last follow-up. Three patients suffered symptomatic adjacent segment degeneration (ASD). No significant difference was detected in the outcomes between 1- and 2-level corpectomy at follow-ups. In conclusion, the satisfactory outcomes in this study indicated that the n-HA/PA66 strut was an effective graft for cervical reconstruction. Moreover, the osteoconductivity and osseointegration of the strut is still need to be optimized for future clinical application owing to the notably presence of “radiolucent gap” in present study.

    Full Text Available Introduction: A microsurgical anterior cervical approach with discectomy and fusion (MACDF is one of the most widely used procedures for treating radicular disorders. This approach is highly successful; however, it is not free from complications. These can be associated with soft tissue injuries. Aim of the Study: The recognition of the risks for these complications should be identified for timely prevention and safe treatment. Materials and Methods: Study Design: Retrospective case control study. This study includes a retrospective case series of 37 patients, paying special attention to immediate complications related to the use of mechanical retraction of soft tissue (dysphagia, dysphonia, esophageal lesions and local hematoma; and a comparative analysis of the outcomes after changes in the retraction method. Results: All selected cases had a positive neurological symptom response in relation to neuropathic pain. Dysphagia and dysphonia were found during the first 72 h in 94.1% of the cases in which automatic mechanical retraction was used for more than one hour during the surgical procedure. A radical change was noted in the reduction of the symptoms after the use of only manual protective blades without automatic mechanical retraction: 5.1% dysphagia and 0% dysphonia in the immediate post-operative period, P = 0.001. Conclusions: Soft tissue damage due to the use of automatic retractors in MACDF is not minor and leads to general discomfort in the patient in spite of good neurological results. These problems most often occur when automatic retractors are used continuously for more than 1 hour, as well as when they are used in multiple levels. Dysphagia, dysphonia and local pain decreased with the use of transient manual blades for retraction, and with intermittent release following minimally invasive principles.

    Full Text Available Abstract Background Titanium (TTN cages have a higher modulus of elasticity when compared with polyetheretherketone (PEEK cages. This suggests that TTN-cages could show more frequent cage subsidence after anterior cervical discectomy and fusion (ACDF and therefore might lead to a higher loss of correction. We compared the long term results of stand-alone PEEK- and TTN-cages in a comparable patient collective that was operated under identical operative settings. Methods From 2002 to 2007 154 patients underwent single-level ACDF for degenerative disc disease (DDD. Clinical and radiological outcome were assessed in 86 eligible patients after a mean of 28.4 months. 44 patients received a TTN- and 42 patients a PEEK-cage. Results Solid arthrodesis was found in 93.2% of the TTN-group and 88.1% of the PEEK-group. Cage subsidence was observed in 20.5% of the TTN- and 14.3% of the PEEK-group. A significant segmental lordotic correction was achieved by both cage-types. Even though a loss of correction was found at the last follow-up in both groups, it did not reach the level of statistical significance. Statistical analysis of these results revealed no differences between the TTN- and PEEK-group. When assessed with the neck disability index (NDI, the visual analogue scale (VAS of neck and arm pain and Odom’s criteria the clinical data showed no significant differences between the groups. Conclusions Clinical and radiological outcomes of ACDF with TTN- or PEEK-cages do not appear to be influenced by the chosen synthetic graft. The modulus of elasticity represents only one of many physical properties of a cage. Design, shape, size, surface architecture of a cage as well as bone density, endplate preparation and applied distraction during surgery need to be considered as further important factors.

    OBJECTIVE Recurrent laryngeal nerve (RLN) injury is one of the most frequent complications of anterior cervical discectomy and fusion (ACDF) procedures. The frequency of RLN is reported as 1%-11% in the literature. (4 , 15) The rate of palsy after reoperative ACDF surgery is not well defined. This meta-analysis was performed to review the current medical evidence on RLN injury after ACDF surgery and to determine a relative rate of RLN injury after reoperative ACDF. METHODS MEDLINE, PubMed, and Google Scholar searches were performed using several key words and phrases related to ACDF surgery. Included studies were written in English, addressed revisionary ACDF surgery, and studied outcomes of RLN injury. Statistical analysis was then performed using a random-effects model to calculate a pooled rate of RLN injury. The heterogeneity of the studies was assessed using Cochran's Q statistic and I(2) statistic, and a funnel plot was constructed to evaluate publication bias. RESULTS The search initially identified 345 articles on this topic. Eight clinical articles that met all inclusion criteria were included in the meta-analysis. A total of 238 patients were found to have undergone reoperative ACDF. Thirty-three of those patients experienced an RLN injury. This analysis identified a rate of RLN injury in the literature after reoperative ACDF of 14.1% (95% confidence interval [CI] 9.8%-19.1%). CONCLUSIONS The rate of RLN palsy of 14.1% was greater than any published rate of RLN injury after primary ACDF operations, suggesting that there is a greater risk of hoarseness and dysphagia with reoperative ACDF surgeries than with primary procedures as reported in these studies.

    Dysphonia and dysphagia are common complications of anterior cervical discectomy (ACD). We sought to determine the relationship between dysphagia and in-hospital mortality, complications, speech therapy/dysphagia training, length of hospitalization, and costs associated with ACD. Discharge data from the Nationwide Inpatient Sample for 1,649,871 patients who underwent ACD of fewer than four vertebrae for benign acquired disease between 2001 and 2010 were analyzed using cross-tabulations and multivariate regression modeling. Dysphagia was reported in 32,922 cases (2.0 %). Speech therapy/dysphagia training was reported in less than 0.1 % of all cases and in only 0.2 % of patients with dysphagia. Dysphagia was significantly associated with age ≥65 years (OR = 1.5 [95 % CI 1.4-1.7], P prosthesis placement (OR = 1.5 [1.0-2.0], P = 0.029), and vocal cord paralysis (OR = 11.6 [8.3-16.1], P vocal cord paralysis, and aspiration pneumonia were significant predictors of increased length of hospitalization and hospital-related costs, with aspiration pneumonia having the single largest impact on length of hospitalization and costs. Dysphagia is significantly associated with increased morbidity, length of hospitalization, and hospital-related costs in ACD patients. Despite the known risk of dysphagia in ACD patients and an established role for the speech-language pathologist in dysphagia management, speech-language pathology intervention appears underutilized in this population.

    The purpose of this study was to describe the clinical features of noncontiguous cervical degenerative disc disease (cDDD), investigate the efficacy and complications of a stand-alone anchored spacer (SAAS) for patients with noncontiguous cDDD, and present radiologic analysis of the intermediate segment (IS) after skip-level fusion. Nineteen consecutive patients with noncontiguous cDDD who underwent skip-level anterior cervical discectomy and fusion (ACDF) with SAAS from January 2010 to December 2012 were enrolled in this study. Clinical outcomes were assessed preoperatively and at 24 months postoperatively using the Japanese Orthopaedic Association score, Neck Disability Index, and Visual Analog Scale. Overall cervical alignment (OCA) of the cervical spine, and the range of motion (ROM), intervertebral disc height (IDH), disc signal intensity and disc protrusion of IS were measured and compared before and after surgery. Clinical outcomes significantly improved compared to preoperative scores. The OCA was corrected and maintained at 24 months postoperatively compared with preoperative values (p0.05). However, decreased signal intensity on T2-weighted MRI was evidenced in three mobile IS at final follow-up (20.0%). Skip-level ACDF with SAAS may be an efficacious option for the treatment of noncontiguous cDDD. PMID:26597607

    This report presents two cases of cervicobrachialgia and radiculopathy due to multiple cervical herniated discs and spur formation that dealt with anterior cervical discectomy and fusion (ACDF) using different titanium interbody cages. The description of the clinical presentation, magnetic resonance imaging (MRI) appearances and management strategy are discussed. Both cases showed chronic neck pain and radiating pain from the shoulder to the arm. They had a history of blurry vision, cluster head ache, weakness, and numbness on the shoulder for 2 years. MRI revealed multiple herniated discs between C4-7 and accompanied by the spur formation leading to the narrowness of the spinal canal and its foramina bilaterally. ACDF were performed and complete decompression of the spinal canal and its foramina were carried out. Twin M-cages (Ammtec Inc.-Japan) were placed in the first case at C5-7 levels and single cage of Smith Robinson (SR) was placed in the second case at C5-6 levels. There were no more blurry vision, cluster headache, weakness, and numbness, immediately after surgery. To our knowledge, this is the first reported cases of ACDF, using twin M-cages and single SR cage in Indonesia, with improvement immediately after surgery. Cervical spondylosis can present with cervicobrachialgia and radiculopathy and surgical treatment produces good functional outcome. PMID:27695567

    Full Text Available This study aimed to investigate the mid- to long-term outcomes of cervical disc arthroplasty (CDA versus anterior cervical discectomy and fusion (ACDF for the treatment of 1-level or 2-level symptomatic cervical disc disease.Medline, Embase, and the Cochrane Central Register of Controlled Trials databases were searched to identify relevant randomized controlled trials that reported mid- to long-term outcomes (at least 48 months of CDA versus ACDF. All data were analyzed by Review Manager 5.3 software. The relative risk (RR and 95% confidence intervals (CIs were calculated for dichotomous variables. The weighted mean difference (WMD and 95%CIs were calculated for continuous variables. A random effect model was used for heterogeneous data; otherwise, a fixed effect model was used.Eight prospective randomized controlled trials (RCTs were retrieved in this meta-analysis, including 1317 and 1051 patients in CDA and ACDF groups, respectively. Patients after an ACDF had a significantly lower rate of follow-up than that after CDA. Pooled analysis showed patients in CDA group achieved significantly higher rates of overall success, Neck Disability Index (NDI success, neurological success and significantly lower rates of implant/surgery-related serious adverse events and secondary procedure compared with that in ACDF group. The long-term functional outcomes (NDI, Visual Analog Scale (VAS neck and arm pain scores, the Short Form 36 Health Survey physical component score (SF-36 PCS, patient satisfaction and recommendation, and the incidence of superior adjacent segment degeneration also favored patients in CDA group with statistical difference. Regarding inferior adjacent segment degeneration, patients in CDA group had a lower rate without statistical significance.This meta-analysis showed that cervical disc arthroplasty was superior over anterior discectomy and fusion for the treatment of symptomatic cervical disc disease in terms of overall success, NDI

    Conclusions : Patients undergoing an anterior revision surgery for ASD after ACDF have higher rates of postoperative radiculopathy and redevelopment of ASD when compared with posteriorly approached patients. Patients receiving posterior revision surgery had higher intraoperative blood loss, hospitalizations, and postoperative complications such as wound infections and discharge to rehabilitation, but had a statistically lower chance of redevelopment of ASD requiring secondary revision surgery. This may be due to the fact that posterior revision surgeries involved more levels fused. This study provides one of the longest and most comprehensive follow-ups of this challenging patient population. Prospective studies comparing surgical approaches and techniques are needed to corroborate our findings.

    Background and Aim. First-line treatment strategy for managing cervical disc herniation is conservative measures. In some cases, surgery is indicated either due to signs/symptoms of severe/progressive neurological deficits, or because of persistence of radicular pain despite 12 weeks of conservative treatment. Success for treatment of cervical disc herniation using ACDF has been successfully reported in the literature. We aim to determine the outcome of ACDF in treatment of cervical disc herniation among Iranians. Methods and Materials/Patients. In a retrospective cohort study, we evaluated 68 patients who had undergone ACDF for cervical disc herniation from March 2006 to March 2011. Outcome tools were as follows: (1) study-designed questionnaire that addressed residual and/or new complaints and subjective satisfaction with the operation; (2) recent (one week prior to the interview) postoperative VAS for neck and upper extremity radicular pain; (3) Japanese Orthopaedic Association Myelopathy Evaluation Questionnaire (JOACMEQ) (standard Persian version); and (4) follow-up cervical Magnetic Resonance Imaging (MRI) and lateral X-ray. Results. With mean follow-up time of 52.93 (months) ± 31.89 SD (range: 13-131 months), we had success rates with regard to ΔVAS for neck and radicular pain of 88.2% and 89.7%, respectively. Except QOL functional score of JOAMEQ, 100% success rate for the other 4 functional scores of JOAMEQ was achieved. Conclusion. ACDF is a successful surgical technique for the management of cervical disc herniation among Iranian population.

  10. Pelvic Floor Support Defect in Apical Anterior Vaginal Prolapse with Cervical Hypertrophy. Review with Case Report in a 20-year-old Cadaver.

    Apical anterior vaginal wall prolapse (AVWP) with central defect is uncommon in young non hysterectomized patients causing considerable mortality after the fourth decade of life. Its high propensity to recurrence poses the greatest challenge to pelvic reconstructive surgeons. Approximately 40% of women with prolapse have hypertrophic cervical elongation and the extent of elongation increases with greater degrees of prolapse. Women with prolapse either have inherent hypertrophic elongation of the cervix which predisposes them to prolapse or the downward traction in prolapse leads to cervical elongation. The Pelvic Organ Prolapse Quantification (POP-Q) examination includes measurement of the location of the posterior fornix (point D) with the assumption that this measurement is associated with cervical elongation. Multifocal site involvement with apical and perineal descent primarily afflicts elderly, postmenopausal women after the fourth decade while cervical hypertrophic elongation with prolapse is observed in younger women less than 40 years of age. A review of the anatomical implication of the association of cervical hypertrophy in prolapse is carried out in this article. We observed a combination of distension type anterior vaginal prolapse with apical descent and cervical hypertrophy in a 20-year-old cadaver during routine dissection for undergraduate medical students at Sikkim Manipal Institute of Medical Sciences in 2013. Distension type anterior vaginal prolapse with central defect is rarer as most reported cases are of the displacement type, paravaginal defect. Hypertrophic cervical elongation is either the cause or consequence of prolapse and its identification before reconstructive surgery is paramount as uterine suspension in the face of cervical elongation is contraindicated. Inappropriate identification of all support defects and breaking of tissues is the primary cause of failure of laparoscopic pelvic reconstructive surgery. PMID:26557506

    Full Text Available We are presenting a case of cervical (C4 aneurysmal bone cyst in a 13-year-old girl, came to the outpatient department with neck pain and stiffness since 6 months and normal neurology. We did an en bloc excision of locally aggressive tumor through anterior plus posterior approach and stabilization by lateral mass screw fixation and anterior cervical instrumentation. Involvement of several adjacent cervical vertebrae by an aneurysmal bone cyst is rare, and conventional treatment with curettage and bone grafting is most likely to carry a high rate of recurrence and spinal instability. We recommend complete excision of the tumor and instrumentation in a single stage to avoid instability.

    Clinical features (weakness and amyotrophy of intrinsic hand muscles and obliquely distributed amyotrophy of forearm muscles, figure 1), needle electromyographic findings (distribution of neurogenic activities, figure 2), and pathological findings (ischemic necroses of the anterior horns between C6 and T1, figure 3) of Hirayama disease suggest that understanding of somatotopic representation of the anterior horn innervating arm muscles in the cervical enlargement of spinal cord differs from the known doctrine. Anterior horn cells of the intrinsic hand muscles are located between C7 and T1, those of forearm muscles and triceps brachii muscle as elbow extensor are, contrary to the known doctrine, located in C5 and C6, and those of elbow flexors such as biceps brachii and brachioradialis are located in C4 and above (figure 5). Development of dexterity in human hand may reflect development of cervical enlargement in accord with larger areas representing the hand and fingers on cerebral motor cortex.

    Full Text Available Abstract Background PROCON was designed to assess the clinical outcome, development of adjacent disc disease and costs of cervical anterior discectomy without fusion, with fusion using a stand alone cage and implantation of a Bryan's disc prosthesis. Description of rationale and design of PROCON trial and discussion of its strengths and limitations. Methods/Design Since proof justifying the use of implants or arthroplasty after cervical anterior discectomy is lacking, PROCON was designed. PROCON is a multicenter, randomized controlled trial comparing cervical anterior discectomy without fusion, with fusion with a stand alone cage or with implantation of a disc. The study population will be enrolled from patients with a single level cervical disc disease without myelopathic signs. Each treatment arm will need 90 patients. The patients will be followed for a minimum of five years, with visits scheduled at 6 weeks, 3 months, 12 months, and then yearly. At one year postoperatively, clinical outcome and self reported outcomes will be evaluated. At five years, the development of adjacent disc disease will be investigated. Discussion The results of this study will contribute to the discussion whether additional fusion or arthroplasty is needed and cost effective.

    We report the case of a 41-year-old woman who underwent cervical total disc replacement at C4C5 and C5C6 levels and fusion at C6C7 level through an anterior right-side approach. After anesthesia recovery, the patient presented left hemiparesia and facial palsy due to large right hemispheric stroke. Diffusion-weighted magnetic resonance imaging was performed as soon as the patient developed neurologic symptoms of stroke and revealed a right internal carotid artery dissection. Digital substraction angiography, endovascular stenting, angioplasty and thrombectomy were performed. Six months after treatment, clinical examination showed mild left-arm spasticity. To the best of our knowledge, only two cases of internal carotid artery stroke without dissection or thrombosis are reported. In conclusion, although vascular complications are rare after anterior cervical spine procedure, internal carotid artery dissection can occur. Suspected risk factors are prolonged retraction of the carotid artery and neck extension.

The motion segment C3–C4 was first tested intact; the following groups were tested after complete discectomy: autologous tricortical iliac crest bone graft, Medtronic–Wego polyetheretherketone (PEEK cage, Solis PEEK cage, and BCFC. The autologous bone graft group was tested with an anterior plate. The mean range of motion (ROM was calculated from the load-displacement curves.Results: BCFC significantly decreased ROM in lateral bending and axial rotation compared to other implants, and no significant difference in ROM between two types of PEEK cages and BCFC could be observed in flexion and extension. Anterior cervical plate (ACP significantly decreased ROM in flexion and extension, but no significant difference in ROM between BCFC and bone graft plus ACP could be determined in lateral bending and axial rotation.Conclusion: The BCFC device showed better stability to autologous tricortical iliac crest bone graft and PEEK cages in single-level anterior cervical discectomy and fusion models and thus may be a potential alternative to the current PEEK cages.Keywords: biomechanics, cervical spine, cages, bioabsorbable, sheep

    BACKGROUND CONTEXT: Dysphagia is a frequent complication after anterior cervical interbody fusion (ACIF). Although dysphagia usually improves over 6 months, it remains a significant and persistent problem for some patients. The etiology is poorly understood but has been reported to be associated with vocal cord paralysis, dislodgement of instrumentation and unidentified causes, such as hematoma, adhesion formation and denervation of the pharyngeal plexus. A surgical treatment of dysphagia after ACIF has not been reported.

    Full Text Available Background : The authors have focused their attention to the radiological durability of cervical sagittal alignment after anterior cervical discectomy and fusion (ACDF using autologous bone grafting. Materials and Methods : Among the patients who underwent ACDF with trans-unco-discal (TUD approach between 1976 and 1997, 22 patients (16 males and 6 females made return visits for a clinical evaluation. Patients with trauma or previously treated by anterior cervical fusion or by posterior decompression were excluded from the present study. Clinical evaluation included adjacent segment degeneration (ASD, osseous fusion, local angle at the fused segments and C2-7 angle of cervical spine. Results : The duration after ACDF ranged from 13 to 34 years with an average of 21.3 ± 7.0 years. A single level fusion was done on 8 patients, 2 levels on 11 patients, 3 levels on 2 patients, and 4 levels on 1 patient. Imaging studies indicated that 12 of the 22 patients (54.5% were graded as having symptomatic ASD. Osseous bony fusion at ACDF was recognized in all cases. None of the patients demonstrated kyphotic malalignment of the cervical spine. Average degrees of local angle at the fused segments and the C2-7 angle were 7.06 and 17.6, respectively. Statistical analysis indicated a significant relationship between the local at the fused segments and C2-7 angles. Conclusions : Sagittal alignment of the cervical spine was durable long after ACDF when the local angle at the fused segments was well stabilized.

    Objective To compare the clinical effect and radiological results between anterior cervical corpectomy with fusion (ACCF) and anterior cervical discectomy with fusion (ACDF) in the treatment of nulttilevel cervical spondylosis.Methods A total of 118 patients with multilevel cervical spondylosis who underwent ACCF or ACDF from June 2002 to June 2007 were analyzed respectively. And the patients were divided into Group A (2-level treated with ACCF, n = 33), Group B (2-level treated with ACDF,n =30), Group C (3-level treated with ACCF, n=28), Group D (3-level treated with ACDF,n=27) The clinical outcomes were compared between Group A and Group B, and also between Group C and Group D.Results Compared with Group B, Group A had shorter operation time and a higher postoperative 3 months fusion rate, and the differences were statistically significant ( P <0. 05 ). Compared with Group D, Group C had more blood loss in operation lower fusion rate and lower increased height of fusion segment of postoperative 3 months, and the differences were statistically significant ( P <0. 05 ); but the postoperative curvature of fusion segment of Group C was better than that of Group D and the differences were statistically significant ( P < 0. 05). Tne differences of other datas between Group A and Group B or Group C and Group D were not statistially significant ( P > 0. 05 ). Conclusion For patients with 2-level cervical spondylosis, ACCF and ACDF are both effective operation types; but the ACCF has a better field of vision than ACDF. For patients with 3-level cervical spondylosis, both operation types can be used; and the postoperative curvature of fusion segment of ACDF was worse than ACCF, but cage subsidence maybe occur after ACCF.%目的 比较椎体次全切除减压植骨融合术(anterior cervical corpectomy with fusion,ACCF)和经椎间隙减压植骨融合术(anterior cervical discectomy with fusion,ACDF)治疗多节段颈椎病的临床疗效及影像学结果.方法

    Forestier's disease or diffuse idiophatic skeletal hyperostosis is a systemic reumathological abnormality of unknown etiology. It produces calcificationossification of the anterior longitudinal ligament. The low dorsal region is the most affected in the raquis. These patients are tipically asymptomatic or with few symptoms (minimal joint pain, spinal pain, stiffness). Dysphagia is the most common symptom when the disease affects the cervical spine; less frequent is dyspnea, both secondary to extrinsic compression of the esophagus and trachea. Neurological complaints are quite rare. In the 1970s Resnick described specific radiological criteria for the diagnosis of Forestier's disease that are still used today. It affects men more frequently than women (2:1); the peak occurrence is in patients in their 60s. We present two cases diagnosed by severe difficulty with deglution, a 84 years-old woman and a 54 years-old man; we operated on them for surgical decompression of the esophagus with resection of osteophytes C3-C4 and C5-C6 respectively through a conventional anterolateral neck approach. Relief of difficulty in swallowing was immediately ensued.

    Full Text Available This was an in vitro and in vivo study to develop a novel artificial cervical vertebra and intervertebral complex (ACVC joint in a goat model to provide a new method for treating degenerative disc disease in the cervical spine. The objectives of this study were to test the safety, validity, and effectiveness of ACVC by goat model and to provide preclinical data for a clinical trial in humans in future. We designed the ACVC based on the radiological and anatomical data on goat and human cervical spines, established an animal model by implanting the ACVC into goat cervical spines in vitro prior to in vivo implantation through the anterior approach, and evaluated clinical, radiological, biomechanical parameters after implantation. The X-ray radiological data revealed similarities between goat and human intervertebral angles at the levels of C2-3, C3-4, and C4-5, and between goat and human lordosis angles at the levels of C3-4 and C4-5. In the in vivo implantation, the goats successfully endured the entire experimental procedure and recovered well after the surgery. The radiological results showed that there was no dislocation of the ACVC and that the ACVC successfully restored the intervertebral disc height after the surgery. The biomechanical data showed that there was no significant difference in range of motion (ROM or neural zone (NZ between the control group and the ACVC group in flexion-extension and lateral bending before or after the fatigue test. The ROM and NZ of the ACVC group were greater than those of the control group for rotation. In conclusion, the goat provides an excellent animal model for the biomechanical study of the cervical spine. The ACVC is able to provide instant stability after surgery and to preserve normal motion in the cervical spine.

    The purpose of this study was to find whether excessive distraction of the disc space for cage insertion was a risk factor for adjacent segment degeneration (ASD) after anterior cervical decompression and fusion (ACDF). One hundred and sixteen consecutive patients who underwent ACDF for single-level cervical disc herniation between June 2006 and November 2008 were retrospectively reviewed. Preoperative, postoperative and final follow-up disc height (DH), sagittal segmental alignment (SSA), and sagittal alignment of the cervical spine (SACS) were measured and compared between the ASD group and non-ASD group. In 116 patients, ASD was radiographically proven in 28 (24.1%) patients. The clinical outcomes were significantly improved compared to the preoperative scores in both groups. However, the postoperative and final follow-up DH of the ASD group were significantly higher than in the non-ASD group (p<0.05). In addition, the postoperative DH was significantly correlated with the postoperative or final follow-up SSA (p<0.05). However, postoperative DH was not found to significantly correlate with postoperative or final follow-up SACS (p=0.072 and p=0.096, respectively). Multivariate analysis showed that postoperative DH was the most significant risk factor for ASD. The clinical outcomes of ACDF for single-level degenerative cervical disc disease were satisfactory. Postoperative DH (the distracted distance) had the greatest impact on the incidence of ASD. Excessive disc space distraction is a considerable risk factor for the development of radiographic ASD.

    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.

    Full Text Available OBJECTIVE: The anterior approach for multilevel CSM has been developed and obtained favorable outcomes. However, the operation difficulty, invasiveness and operative risks increase when multi-level involved. This study was to assess surgical parameters, complications, clinical and radiological outcomes in the treatment of 2-, 3- and 4-level CSM. METHODS: A total of 248 patients with 2-, 3- or 4-level CSM who underwent anterior decompression and fusion procedures between October 2005 and June 2011 were divided into three groups, the 2-level group (106 patients, the 3-level group (98 patients and the 4-level group (44 patients. The clinical and Radiographic outcomes including Japanese Orthopedic Association (JOA score, Neck Disability Index (NDI score, Odom's Scale, hospital stay, blood loss, operation time, fusion rate, cervical lordosis, cervical range of motion (ROM, and complications were compared. RESULTS: At a minimum of 2-year follow-up, no statistical differences in JOA score, NDI score, Odom's Scale, hospital stay, fusion rate and cervical lordosis were found among the 3 groups. However, the mean postoperative NDI score of the 4-level group was significantly higher than that in the other two groups (P<0.05, and in terms of postoperative total ROM, the 3-level group was superior to the 4-level group and inferior to 2-level group (P<0.05. The decrease rate of ROM in the 3-level group was significantly higher than that in the 2-level group, and lower than that in the 4-level group (P<0.05. CONCLUSIONS: As the number of involved levels increased, surgical results become worse in terms of operative time, blood loss, NDI score, cervical ROM and complication rates postoperatively. An appropriate surgical procedure for multilevel CSM should be chosen according to comprehensive clinical evaluation before operation, thus reducing fusion and decompression levels if possible.

    BACKGROUND:Bioactive glass has been largely reported to have perfect clinical results in the bone nonunion and fracture healing, but its effect during spinal fusion progress is rarely reported. OBJECTIVE:To explore the safety and effectiveness of anterior cervical discectomy and fusion by cervical cage with bioactive glass METHODS:A total of 68 cases of cervical spondylosis myelopathy were treated with single level anterior cervical discectomy and fusion. Their clinical data were retrospectively analyzed. Al the cases underwent polyetheretherketone cervical cage with autogenous bone (n=32, control group) or bioactive glass (n=32, experimental group). The bone fusion, neurological functional recovery, intervertebral height, change of cervical curve and wound complications in the two groups was recorded and analyzed. RESULTS AND CONCLUSION:Neurological improvement had no difference between the two groups and there was no complication about wound, such as infection and delayed healing. The average rate of bone fusion was 97%in the control group while 94%in the experiment group 3 months after operation which had no significant differences. Six months after operation, al cases gained bone fusion. The intervertebral height and change of cervical curve both maintained wel in the two groups within 3, 6, 12 months after operation which had no significant differences between the two groups. So, anterior cervical discectomy and fusion by cervical cage with bioactive glass is safe and effective.%背景:已有文献报道生物活性玻璃在骨不连、骨折愈合过程中有较佳的临床疗效,但其在脊柱骨融合过程中的效果鲜有报道。  目的:观察生物活性玻璃联合颈椎椎间融合器在颈椎前路椎间融合中应用的安全性和有效性。  方法:回顾性分析68例颈椎前路单节段椎间融合患者资料,全部病例均采用聚醚醚酮材料椎间融合器,其中内填充自体松质骨植骨32

    Full Text Available OBJETIVO: Descrever a anatomia do nervo laríngeo recorrente (NLR bilateralmente, correlacionando-a com os prováveis mecanismos de lesão na abordagem cervical anterior. MÉTODO: Foram examinados 12 cadáveres de adultos provenientes do Laboratório de Microcirurgia da Faculdade de Medicina da UFMG. Os dados foram analisados em termos de freqüência, média e desvio-padrão. RESULTADOS: O NLR esquerdo teve comprimento total médio de 9,4 ± 1,6 cm. Penetra na laringe em 36,3% dos casos na altura de C5, 18,2% de C4, 18,2% de C5-C6, 18,2% de C6 e 9,1% de C4-C5. Recorre em 45,4% dos casos na altura de T3, 18,2% de T3-T4, 18,2% de T4 e 18,2% de T5. O NLR direito teve comprimento total médio de 5 ± 0,3 cm. Penetra na laringe em 44,4% dos casos na altura de C5, em 44,4% de C6 e 11,1% de C3-C4. Recorre em 60% dos casos na altura de T1, 30% de C7 e 10% de T2. CONCLUSÃO: O NLR direito encontra-se mais vulnerável a lesões operatórias por dois aspectos diferentes e complementares: trajetória e comprimento. Devido ao fato de apresentar trajetória mais oblíqua e desprotegida, não se relacionando de forma íntima com o sulco traqueoesofágico, existe maior possibilidade de ocorrerem traumas diretos, como a compressão por retratores ou a secção acidental, principalmente nas abordagens envolvendo níveis vertebrais mais baixos. Da mesma forma, o seu menor comprimento favorece o estiramento de suas fibras durante a tração per-operatória.OBJECTIVE: To present an anatomical description of the recurrent laryngeal nerve (RLN on both sides of the larynx as it relates to the possible lesion mechanisms in anterior cervical spine surgery.

    The surgical treatment of cervical kyphotic deformity remains challenging. As a surgical method that is safer and avoids major complications, the authors present a procedure of single-stage anterior and posterior fusion to correct cervical kyphosis using anterior interbody fusion cages without plating, as illustrated by three consecutive cases. Case 1 was a 78-year-old woman who presented with a dropped head caused by degeneration of her cervical spine. Case 2 was a 54-year-old woman with athetoid cerebral palsy. She presented with cervical myelopathy and cervical kyphosis. Case 3 was a 71-year-old woman with cervical kyphotic deformity following a laminectomy. All three patients underwent anterior release and interbody fusion with cages and posterior fusion with cervical lateral mass screw (LMS) fixation. Postoperative radiographs showed that correction of kyphosis was 39° in case 1, 43° in case 2, and 39° in case 3. In all three cases, improvement of symptoms was established without major perioperative complications, solid fusion was achieved, and no loss of correction was observed at a minimum follow-up of 61 months. We also report that preoperative total spine sagittal malalignment was improved after corrective surgery for cervical kyphosis and was maintained at the latest follow-up in all three cases. The combination of anterior fusion cages and LMS is considered a safe and effective procedure in cases of severe cervical kyphotic deformity. Preoperative total spine sagittal malalignment improved, accompanied by correction of cervical kyphosis, and was maintained at last follow-up in all three cases. PMID:26119893

    OBJECTIVE The purpose of this study was to present an initial surgical experience in the management of 1- or 2-level degenerative disc disease of the cervical spine using biodegradable anterior cervical plates (bACPs) in anterior cervical discectomy and fusion (ACDF). The authors also aimed to provide insight into this critical and controversial clinical issue by clarifying outcomes for patients receiving bACPs and by comparing their outcomes with those achieved using a traditional metallic anterior cervical plate (mACP) implant. METHODS A retrospective review was conducted for 2 series of patients who had undergone ACDF using either bACP (31 patients, 38 segments) or mACP (47 patients, 57 segments) instrumentation. The patients were followed up for a mean 13.5 ± 0.9 months (range 12-18 months) in the bACP group and 14.8 ± 1.5 months (range 14-22 months) in the mACP group. Clinical outcomes were determined according to scores on the visual analog scale (VAS), the modified Japanese Orthopaedic Association (mJOA) scoring system, and Odom's criteria. Radiological images were used to assess fusion rates, intervertebral height, Cobb's angle, and the width of prevertebral soft tissue. RESULTS Both VAS and mJOA scores were significantly improved at each follow-up in both groups. Excellent or good results according to Odom's criteria were achieved in 93.5% (29/31) of patients in the bACP group and 93.6% (44/47) of patients in the mACP group. At 6 months postoperatively, the fusion rate was 94.7% (36/38) in the bACP group and 96.5% (55/57) in the mACP group, but subsidence of the intervertebral space at the surgical level was more evident in the bACP group. Angulation, as measured by Cobb's angle, demonstrated obvious healing in both groups, while better maintenance was observed in the mACP group. The local inflammatory reaction was uneventful during follow-up. Dysphonia and dysphagia were observed in both groups during the follow-up. CONCLUSIONS The relatively comparable

    Background and Objectives: The aim of the study was to determine the effect of two access cavity designs on the peri-cervical dentin thickness before and after instrumentation using cone beam computed tomography (CBCT). Materials and Methods: Sixty mandibular anterior teeth were divided into two groups of thirty teeth each: Group I: conventional access cavity preparation, where access was prepared just above the cingulum and Group II: incisal access cavity preparation, where access was prepared in proximity to the incisal edge. CBCT scans were taken preoperatively, following access cavity preparation and post instrumentation. 200 μm thick slices were obtained 4mm apical and coronal to the cemento-enamel junction. The peri-cervical dentin thickness was calculated on the facial, lingual, mesial, and distal for all the three obtained scans. Results: The analysis showed that access cavity preparation and instrumentation resulted in a significant loss of tooth structure in Group I on all surfaces, but in Group II, there was a significant loss of tooth structure only in the mesial, lingual, and distal surfaces (P < 0.05). Conclusion: Incisal access cavity preparation resulted in lesser loss of dentin in the peri-cervical region. PMID:27656065

    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.

    Cervical radiculopathy is a common clinical scenario. Patients with radiculopathy typically present with neck pain, arm pain, or both. We review the epidemiology of cervical radiculopathy and discuss the diagnosis of this condition. This includes an overview of the pertinent findings on the patient history and physical examination. We also discuss relevant clinical syndromes that must be considered in the differential diagnosis including peripheral nerve entrapment syndromes and shoulder pathology. The natural history of cervical radiculopathy is reviewed and options for management are discussed. These options include conservative management, non-operative modalities such as physical therapy, steroid injections, and operative intervention. While the exact indications for surgical intervention have not yet been elucidated, we provide an overview of the available literature regarding indications and discuss the timing of intervention. The surgical outcomes of anterior cervical decompression and fusion (ACDF), cervical disc arthroplasty (CDA), and posterior cervical foraminotomy (PCF) are discussed. PMID:27250042

  4. Narrative review of the in vivo mechanics of the cervical spine after anterior arthrodesis as revealed by dynamic biplane radiography.

    2016-01-01

    Arthrodesis is the standard of care for numerous pathologic conditions of the cervical spine and is performed over 150,000 times annually in the United States. The primary long-term concern after this surgery is adjacent segment disease (ASD), defined as new clinical symptoms adjacent to a previous fusion. The incidence of adjacent segment disease is approximately 3% per year, meaning that within 10 years of the initial surgery, approximately 25% of cervical arthrodesis patients require a second procedure to address symptomatic adjacent segment degeneration. Despite the high incidence of ASD, until recently, there was little data available to characterize in vivo adjacent segment mechanics during dynamic motion. This manuscript reviews recent advances in our knowledge of adjacent segment mechanics after cervical arthrodesis that have been facilitated by the use of dynamic biplane radiography. The primary observations from these studies are that current in vitro test paradigms often fail to replicate in vivo spine mechanics before and after arthrodesis, that intervertebral mechanics vary among cervical motion segments, and that joint arthrokinematics (i.e., the interactions between adjacent vertebrae) are superior to traditional kinematics measurements for identifying altered adjacent segment mechanics after arthrodesis. Future research challenges are identified, including improving the biofidelity of in vitro tests, determining the natural history of in vivo spine mechanics, conducting prospective longitudinal studies on adjacent segment kinematics and arthrokinematics after single and multiple-level arthrodesis, and creating subject-specific computational models to accurately estimate muscle forces and tissue loading in the spine during dynamic activities.

    Full Text Available Background: In the surgical treatment of thoracolumbar fractures, the major problem after posterior correction and transpedicular instrumentation is failure to support the anterior spinal column, leading to loss of correction and instrumentation failure with associated complaints. We conducted this prospective study to evaluate the outcome of the treatment of acute thoracolumbar burst fractures by transpedicular balloon kyphoplasty, grafting with calcium phosphate cement and short pedicle screw fixation plus fusion. Materials and Methods : Twenty-three consecutive patients of thoracolumbar (T 9 to L 4 burst fracture with or without neurologic deficit with an average age of 43 years, were included in this prospective study. Twenty-one from the 23 patients had single burst fracture while the remaining two patients had a burst fracture and additionally an adjacent A1-type fracture. On admission six (26% out of 23 patients had neurological deficit (five incomplete, one complete. Bilateral transpedicular balloon kyphoplasty with liquid calcium phosphate to reduce segmental kyphosis and restore vertebral body height and short (three vertebrae pedicle screw instrumentation with posterolateral fusion was performed. Gardner kyphosis angle, anterior and posterior vertebral body height ratio and spinal canal encroachment were calculated pre- to postoperatively. Results : All 23 patients were operated within two days after admission and were followed for at least 12 months after index surgery. Operating time and blood loss averaged 45 min and 60 cc respectively. The five patients with incomplete neurological lesions improved by at least one ASIA grade, while no neurological deterioration was observed in any case. The VAS and SF-36 (Role physical and Bodily pain domains were significantly improved postoperatively. Overall sagittal alignment was improved from an average preoperative 16° to one degree kyphosis at final follow-up observation. The anterior

    Full Text Available Background:   After cervical discectomy, autogenetic bone is packed into the cage to increase the rate of union between adjacent vertebral bodies, but donor site–related complications can still occur. In this study we evaluate the use   of hydroxyapatite granules as a substitute for autograft for interbody fusion.     Methods:   From November 2008 to November 2011, 236 patients participated in this study. Peek cages were packed with autologous bone grafts taken from the iliac crest in 112 patients and hydroxyapatite (HA granules in 124 patients.   Patients were followed for 12 months. The patients’ neurological signs, results, and complications were fully recorded   throughout the procedure. Radiological imaging was done to assess the fusion rate and settling ratio.     Results:   Formation of bony bridges at the third month was higher in the autograft group versus the granule group. However, there was no difference between both groups at the 12-month follow-up assessment. No difference (     P > 0.05   was found regarding improvement in neurological deficit as well as radicular pain and recovery rate between the two groups. Conclusions:   Interbody fusion cage containing HA granules proved to be an effective treatment for cervical spondylotic radiculopathy and/or myelopathy. Clinical and neurological outcome, radiographic measurement and fusion rate   in cage containing HA are similar and competitive with autograft packed cages.

    Objective:To determine the effectiveness of posterior Moss-Miami transpedicular system for the treatment of adolescent idiopathic scoliosis in 24 patients with a 2-year minimum follow up. Methods:24 patients who underwent operations between September 2002 and November 2003 were evaluated for curve correction, spinal balance, and complications. Age at surgery averaged 13.8 years (range from 10 to20). The spinal deformities were evaluated by Cobb method with anteroposterior and lateral bending radiographs. All patients were right thoracic curves. Posterior instrumentation (Moss-Miami transpedicular system) was used. The transpedicular screws were placed between T2 and L2. All the patients were assessed both clinically and radiographically. Follow-up averaged 2.8 years. Results: There was an average correction of 72% of the primary curve (pre-operation standing average 54 degrees (range from 40 to 67degrees), post-operation average 15.2 degrees (range from 2 to 27 degrees), at last examination average 16.1 degrees (range from 2 to 30 degrees). Infection and neurological complications were not noted. No major complications were observed. Conclusions: Frontal and sagittal thoracic curve correction of thoracic scoliosis can be satisfactorily obtained using Moss Miami transpedicular instrumentation. It seems that control of the three columns of the spine by the transpedicular screws offers sufficient apical translation and coronal realignment.

    Of twenty-two patients who had had anterior decompression of the spinal canal for ossification of the posterior longitudinal ligament and cervical myelopathy, seven had absence of the dura adjacent to the ossified part of the ligament. The spinal cord and nerve-roots were visible through this defect. Although the arachnoid membrane appeared to be intact and watertight in most patients, a cerebrospinal-fluid fistula developed postoperatively in five, and three had a second operation to repair the defect in the dura. On the basis of this experience, we recommend use of autogenous muscle or fascial dural patches, immediate lumbar subarachnoid shunting, and modification of the usual postoperative regimen, such as limitation of mechanical pulmonary ventilation to the shortest time that is safely possible and use of anti-emetic and antitussive medications to protect the remaining coverings of the spinal cord when the dura is found to be absent adjacent to an ossified portion of the posterior longitudinal ligament in the cervical spine.

    Anterior cervical discectomy and fusion (ACDF) is a widely accepted surgical treatment for symptomatic cervical spondylosis. Some patients develop symptomatic adjacent segment degeneration, occasionally requiring further treatment. The cause and prevalence of adjacent segment degeneration and disease is unclear at present. Proponents for motion preserving surgery such as disc arthroplasty argue that this technique may decrease the "strain" on adjacent discs and thus decrease the incidence of symptomatic adjacent segment degeneration. The purpose of this study was to assess the pre-operative prevalence of adjacent segment degeneration in patients undergoing ACDF. A database review of three surgeons' practice was carried out to identify patients who had undergone a one- or two-level ACDF for degenerative disc disease. Patients were excluded if they were operated on for recent trauma, had an inflammatory arthropathy (for example, rheumatoid arthritis), or had previous spine surgery. The pre-operative MRI of each patient was reviewed and graded using a standardised methodology. One hundred and six patient MRI studies were reviewed. All patients showed some evidence of intervertebral disc degeneration adjacent to the planned operative segment(s). Increased severity of disc degeneration was associated with increased age and operative level, but was not associated with sagittal alignment. Disc degeneration was more common at levels adjacent to the surgical level than at non-adjacent segments, and was more severe at the superior adjacent level compared with the inferior adjacent level. These findings support the theory that adjacent segment degeneration following ACDF is due in part to the natural history of cervical spondylosis.

  12. Percutaneous coaxial transpedicular biopsy of vertebral body lesions during vertebroplasty

    International Nuclear Information System (INIS)

    We evaluated the safety and histological results of percutaneous transpedicular biopsy in patients undergoing vertebroplasty for vertebral collapse. Over a 6 year period, we carried out biopsies in 46 patients who underwent percutaneous injection of acrylic surgical cement for 57 collapsed vertebrae, because the diagnosis was not clearly established on clinical or imaging grounds. All procedures were performed under fluoroscopic guidance via a coaxial bitranspedicular approach used for vertebroplasty. We performed a clinical examination and CT after every procedure and approximately 6 months thereafter. Biopsies contributed to in 55 (96.5 %) of the 57 vertebral lesions. Biopsy material was inadequate in one case (1.7 %) and one biopsy was a false-negative (1.7 %). The accuracy of the histological results was 98.2 %, allowing a correct diagnosis in 55 of the 56 procedures. Of the 37 lesions in 28 patients with a history of a tumour, the final diagnosis was osteoporotic collapse in 25 (67.6 %), metastasis in nine (24.3 %), and myeloma in three (8.1 %). The final diagnosis in the 19 lesions in 17 patients without a known tumour was osteoporotic collapse in 12 (63.2 %), metastasis in five (26.3 %), and amyloidosis in two (10.5 %), the latter in one patient. No complications were observed. (orig.)

    BackgroundEndovascular aortic repair (EVAR) requires further intervention in 20-30 % of cases, often due to type II endoleak (T2EL). Management options for T2EL include transarterial embolization, direct puncture (DP), or transcaval embolization. We report the case of an 80-year-old man with T2EL who successfully underwent DP embolization.MethodsEmbolization by DP was performed with a transpedicular approach using an isocenter puncture (ISOP) method. An isocenter marker (ICM) was placed at a site corresponding to the aneurysm sac on fluoroscopy in two directions (frontal and lateral views). A vertebroplasty needle was inserted tangentially to the ICM under fluoroscopy and advanced to the anterior wall of the vertebral body. A 20 cm-length, 20-G-PTCD needle was inserted through the outer needle of the 13-G needle and advanced to the ICM. Sac embolization using 25 % N-buty-2-cyanoacrylate diluted with Lipiodol was performed. After complete embolization, rotational DA confirmed good filling of the sac with Lipiodol. The outer cannula and 13-G needle were removed and the procedure was completed.ResultsThe patient was discharged the next day. Contrast-enhanced computed tomography 1 and 8 months later showed no Lipiodol washout in the aneurysm sac, no endoleak recurrence, and no expansion of the excluded aneurysm.ConclusionDP with a transpedicular approach using ISOP may be useful when translumbar and transabdominal approaches prove difficult.

    Full Text Available OBJECTIVE: To retrospectively compare the efficacy of the titanium mesh cage (TMC and the nano-hydroxyapatite/polyamide66 cage (n-HA/PA66 cage for 1- or 2-level anterior cervical corpectomy and fusion (ACCF to treat multilevel cervical spondylotic myelopathy (MCSM. METHODS: A total of 117 consecutive patients with MCSM who underwent 1- or 2-level ACCF using a TMC or an n-HA/PA66 cage were studied retrospectively at a mean follow-up of 45.28 ± 12.83 months. The patients were divided into four groups according to the level of corpectomy (1- or 2-level corpectomy and cage type used (TMC or n-HA/PA66 cage. Clinical and radiological parameters were used to evaluate outcomes. RESULTS: At the one-year follow-up, the fusion rate in the n-HA/PA66 group was higher, albeit non-significantly, than that in the TMC group for both 1- and 2-level ACCF, but the fusion rates of the procedures were almost equal at the final follow-up. The incidence of cage subsidence at the final follow-up was significantly higher in the TMC group than in the n-HA/PA66 group for the 1-level ACCF (24% vs. 4%, p = 0.01, and the difference was greater for the 2-level ACCF between the TMC group and the n-HA/PA66 group (38% vs. 5%, p = 0.01. Meanwhile, a much greater loss of fused height was observed in the TMC group compared with the n-HA/PA66 group for both the 1- and 2-level ACCF. All four groups demonstrated increases in C2-C7 Cobb angle and JOA scores and decreases in VAS at the final follow-up compared with preoperative values. CONCLUSION: The lower incidence of cage subsidence, better maintenance of the height of the fused segment and similar excellent bony fusion indicate that the n-HA/PA66 cage may be a superior alternative to the TMC for cervical reconstruction after cervical corpectomy, in particular for 2-level ACCF.

    Objective To explore the clinical features and operative strategy of upper cervical injury combined with noncontiguous lower cervical fracture. Methods From May 2004 to August 2007,9 cases of upper cervical injury combined noncontiguous lower cervical fracture were treated by one-stage operation. Posterior instrumentation was chosen for the upper cervical injury,including 8 cases of transpedicular screw fixation and fusion on the atlantoaxial vertebra and 1 case of occipital-cervical fixation,Lower cervical fractures were managed by posterior transpedicular screw fixation in 6 cases,including 4 cases of short segmental fix-ation with noncontiguous screws and 2 cases of long segmental fixation with contiguous upper cervical screws. The other 3 cases were treated by anterior lower cervical decompression and titanic plate fixation. Results They were followed up for an average of 13.7 months (from 6 to 48 months) . No injury to the vertebral artery occurred during operation. After operation,no tracheotomy was needed and intubation was not pro-longed. Satisfactory reduction and fusion were obtained,without post-operative complications such as severe pulmonary infection,respiratory failure and stress gastric ulcer. Two lower cervical pedicle screws were bro-ken. Neural function was not improved in 2 cases of preoperative Frankel A and the Frankel scores were E in the other cases. Conclusions Upper cervical injury combined with noncontiguous lower cervical fracture often leads to the utmost instability of the cervical spine and lower cervical neural dysfunction. Appropriate one-stage operative technique,which includes posterior transpedicular screw fixation in the upper and lower cervical spine or anterior lower cervical decompression,is advocated because of its safety and efficacy.%目的 探讨上颈椎损伤合并不连续的下颈椎损伤的临床特点及手术治疗策略.方法 2004年5月至2007年8月,对上颈椎损伤合并不连续的下颈椎损伤9例患

    Full Text Available Abstract Background Anterior cervical discectomy with fusion (ACDF is challenging with respect to both patient selection and choice of surgical procedure. The aim of this study was to evaluate the clinical outcome of ACDF, with respect to both patient selection and choice of surgical procedure: fusion with an autologous iliac crest graft (AICG versus fusion with an artificial cage made of polyetheretherketone (PEEK. Methods This was a non-randomized prospective single-center outcome study of 258 patients who underwent ACDF for cervical disc degeneration (CDD. Fusion was attained with either tricortical AICG or PEEK cages without additional anterior plating, with treatment selected at surgeon's discretion. Radicular pain, neck-pain, headache and patient satisfaction with the treatment were scored using the visual analogue scale (VAS. Results The median age was 47.5 (28.3-82.8 years, and 44% of patients were female. 59% had single-level ACDF, 40% had two level ACDF and 1% had three-level ACDF. Of the patients, 181 were fused with AICG and 77 with a PEEK-cage. After surgery, the patients showed a significant reduction in radicular pain (ΔVAS = 3.05, neck pain (ΔVAS = 2.30 and headache (ΔVAS = 0.55. Six months after surgery, 48% of patients had returned to work: however 24% were still receiving workers' compensation. Using univariate and multivariate analyses we found that high preoperative pain intensity was significantly associated with a decrease in pain intensity after surgery, for all three pain categories. There were no significant correlations between pain relief and the following patient characteristics: fusion method (AICG or PEEK-cage, sex, age, number of levels fused, disc level fused, previous neck surgery (except for neck pain, previous neck trauma, or preoperative symptom duration. Two hundred out of the 256 (78% patients evaluated the surgical result as successful. Only 27/256 (11% classified the surgical result as a failure

    stages. Artificial disc replacement can not only play a role in mitigation of cervical disease neurological symptoms and signs, but also maintain stability and semental activity of cervical spine, and reduce secondary adjacent segmental degeneration. These two methods which applied in cervical degenerative intervertebral disc herniation stil remain controversial. OBJECTIVE:To investigate the short-term effect of artificial cervical disc replacement and anterior cervical decompression and fusion for the treatment of single segmental cervical disc herniation. METHODS:Total y 48 patients with single segment radiculopathy or myelopathy cervical diseases induced by cervical disc herniation that required surgery and received a three-month fol ow-up were included and retrospectively analyzed. These patients were divided into replacement group (n=21) and fusion group (n=27) according to the different repair programs. Patients in the replacement group were subjected to Prestige LP cervical artificial disc replacement, and patients in the fusion group were subjected to disc fusion using interbody fusion cage of Johnson or al ogeneic fibularing. They were fol owed up at 1 week, 3, 6, 12, 24, 36 months after treatment. Complications were recorded during the fol ow-up. The pain of patients was evaluated using neck and upper limb pain visual analogue scale scores. The therapeutic effect was evaluated using Japanese Orthopaedic Association (JOA) score. The clinical symptoms improvement and daily functional status of patients after treatment were evaluated using cervical disability index. RESULTS AND CONCLUSION:During the final fol ow-up, the fusion rate in fusion group was 93%(25/27). Comparisons between groups:at the 1 week and final fol ow-up after treatment, the visual analog scale scores of neck and upper limbs and cervical dysfunction indexes were al lower than those before treatment;the Japanese Orthopaedic Association scores were higher than those before treatment (P0.05).

    : Study Design. Retrospective chart review and literature review.Objective. To identify cases where a CSF leak occurred during an ACDF and to create a management algorithm based on the findings.Summary of Background Data. Anterior cervical discectomy and fusion (ACDF) is a commonly performed spinal operation. It is effective with very low complication rates. One rare complication of ACDF is a CSF leak. There is limited information on the management of CSF leaks following ACDF and management is on a surgeon-by-surgeon basis.Methods. We reviewed 3 surgeons' case logs and identified cases where a CSF leak was encountered during ACDF and reviewed the patients' medical records, operative reports and imaging to determine how these leaks were managed. We also performed a PubMed search for articles about the presentation and management of CSF leaks following ACDF.Results. Thirteen CSF leaks were identified in 1223 ACDFs, corresponding to a CSF leak rate of 1%. Of these, 9 were successfully treated with intraoperative repair. Postoperative lumbar drainage was used in the remaining 4 patients and was successful in 1 patient. Three patients underwent neck re-exploration and attempted delayed repair. Three patients, including one who was found to have hydrocephalus, ultimately required continuous CSF diversion via shunting. We identified 7 case reports of CSF leak in ADCF in the literature and 1 article that reviewed the prevalence and management of this complication.Conclusion. CSF leak following ACDF is an uncommon complication that can usually be repaired. We provide a stepwise management strategy for CSF leaks in ACDF.

    OBJECTIVE The purpose of this study was to report the outcome of a study of 2-level cervical total disc replacement (Mobi-C) versus anterior cervical discectomy and fusion (ACDF). Although the long-term outcome of single-level disc replacement has been extensively described, there have not been previous reports of the 5-year outcome of 2-level cervical disc replacement. METHODS This study reports the 5-year results of a prospective, randomized US FDA investigational device exemption (IDE) study conducted at 24 centers in patients with 2-level, contiguous, cervical spondylosis. Clinical outcomes at up to 60 months were evaluated, including validated outcome measures, incidence of reoperation, and adverse events. The complete study data and methodology were critically reviewed by 3 independent surgeon authors without affiliation with the IDE study or financial or institutional bias toward the study sponsor. RESULTS A total of 225 patients received the Mobi-C cervical total disc replacement device and 105 patients received ACDF. The Mobi-C and ACDF follow-up rates were 90.7% and 86.7%, respectively (p = 0.39), at 60 months. There was significant improvement in all outcome scores relative to baseline at all time points. The Mobi-C patients had significantly more improvement than ACDF patients in terms of Neck Disability Index score, SF-12 Physical Component Summary, and overall satisfaction with treatment at 60 months. The reoperation rate was significantly lower with Mobi-C (4%) versus ACDF (16%). There were no significant differences in the adverse event rate between groups. CONCLUSIONS Both cervical total disc replacement and ACDF significantly improved general and disease-specific measures compared with baseline. However, there was significantly greater improvement in general and disease-specific outcome measures and a lower rate of reoperation in the 2-level disc replacement patients versus ACDF control patients.

    BACKGROUND:Bryan cervical disc replacement and anterior cervical discectomy and fusion have a dispute in the treatment of cervical spondylosis. OBJECTIVE:To evaluate the clinical effects of Bryan cervical disc replacement and anterior cervical discectomy and fusion by meta-analysis, thereby providing clinical evidence for treatment strategy of cervical spondylosis. METHODS:The authors searched Medline, PubMed, EMBASE, OVID, CBM, CNKI and also searched manual y seven relevant Chinese orthopedic journals for articles pertinent to clinical research of Bryan cervical disc replacement and anterior cervical discectomy and fusion. Extracted data included the range of motion of the cervical spine, visual analog scale score, neck disability index, the Japanese Orthopaedic Association score. Meta-analysis and forest plots were conducted with RevMan4.2.2 Software. RESULTS AND CONCLUSION:There are eight articles in the meta-analysis, including 883 patients (430 patients receiving Bryan cervical disc replacement, and 453 patients receiving anterior cervical discectomy and fusion). Meta-analysis did detect statistical y significant differences in the range of motion of the cervical spine at 3 months and 24 months postoperatively between the two groups, but did not detect statistical y significant differences in visual analog scale score, neck disability index, the Japanese Orthopaedic Association score between the two groups. These findings indicate that Bryan cervical disc replacement is superior to anterior cervical discectomy and fusion in the range of motion of the cervical spine. However, the current literature offers no evidence to support superiority of the Bryan cervical disc replacement over the anterior cervical discectomy and fusion.%背景:Bryan颈椎间盘置换与颈前路间盘切除植骨融合治疗颈椎病的临床疗效存在争议。  目的:应用 Meta 分析方法,评价 Bryan 颈椎间盘置换与颈前路间盘切除植骨融合治疗颈椎病

    Objectives: To study biomechanical effects of different anterior decompression and fusion on the stability of cervical vertebrae. Methods: 18 cadaveric specimens of cervical spine were divided into three group randomly: ①anterior cervical discectomy and fusion (ACDF); ②anterior cervical hybrid decompression and fusion(combined with corpectomy and discectomy (ACHDF) ; ③anterior cervical corpectomy and fusion (ACCF); Specimens of every group endured the movements of flexion, extension, lateral bending, and axial rotation. The range of motion of all directions was recorded stereophotogrammetrieally niter flexion-extension fatigue loading of 2000 cycles on the specimens of 3 groups. Results: Anterior plate made all of specimens more stable. After flexion-extension fatigue loading of 1200 cycles, there were no changes of ROM between ACDF and ACHDF groups, however, ROM of ACCF group increased. After 2000 cycles, SPIROM and SPINZ of ACDF and ACHDF groups had no difference, however, that of ACCF group decreased. Conclusions: Three kinds of anterior decompression and fusion technique could restore the stability of cervical vertebrae. Under the fatigue loading, the stability and tolerance of ACDF and ACHDF groups are superior to that of ACCF group.%目的:研究颈椎前路多节段病变不同减压、融合固定方式对生物力学稳定性的影响.方法:18具新鲜人尸体颈椎标本,分别行前路椎间盘切除植骨融合(ACDF)、分节段混合减压植骨融合(ACHDF)及椎体次全切除植骨融合(ACCF)术,依次测定正常状态、减压植骨后、钢板固定后、疲劳2000次后的三维活动度,计算稳定潜能指数(SPI),测定疲劳2000次后尾端螺钉和椎体间的活动度.结果:3种方式减压、植骨、钢板固定后,稳定性均明显提高;届伸疲劳1200次后,ACDF、ACHDF组标准化的螺钉-椎体间活动度曲线无变化,而ACCF组曲线升高;疲劳2000次后,ACDF组三维运动SPIROM及SPINZ无变

    Objective To investigate the efficacy and the selection of surgery time of anterior operation for cervical ossification of posterior longitudinal ligament combined with cervical disc herniation. Methods Totally 24 cases of cervical ossification of posterior longitudinal ligament combined with cervical disc herniation underwent anterior operation in our department from January 2005 to January 2011. There were 21 males and 3 females. The mean age was 52 years old (range; 40-68 years). Preoperatively, 2-3 ossified segments of the posterior longitudinal ligament combined with contiguous cervical herniated disc compressing the spinal cord were revealed through cervical X-ray film, CT and MRI examinations. All patients were treated with the anterior cervical subtotal corpectomy combined with the discectomy of contiguous cervical herniated disc by the cage fusion surgery of internal fixation for reconstruction. The preoperative and postoperative Japanese Orthopaedic Association (JOA) scores were analyzed and compared, and the improvement rate was also calculated. Results All patients were followed up for an average period of 22 months (range; 8-36 months). The mean JOA score of neurological function was preoperatively 7.5 points (range; 4-13 points). The mean JOA score was postoperatively 13.6 points (range; 10-16 points). The mean improvement rate of neurological function was 65.6% (range; 32%-81%). The efficacy of 7 cases was excellent, 12 cases good, 5 cases fair and none bad. The excellence rate was 79.1%. Conclusions Cervical ossification of posterior longitudinal ligament often combines with contiguous cervical herniated disc resulting in spinal cord injury. To avoid the sharp deterioration of spinal cord function, early surgical intervention should be taken. The anterior cervical subtotal corpectomy combined with the discectomy of contiguous cervical herniated disc by the cage fusion surgery of internal fixation for reconstruction in the treatment of cervical

    OBJECTIVE In an era of escalating health care costs and pressure to improve efficiency and cost of care, ambulatory surgery centers (ASCs) have emerged as lower-cost options for many surgical therapies. Anterior cervical discectomy and fusion (ACDF) is one of the most prevalent spine surgeries performed, and the frequency of its performance is rapidly increasing as the aging population grows. Although ASCs offer significant cost advantages over hospital-based surgical centers, concern over the safety of outpatient ACDF has slowed its adoption. The authors intended to 1) determine the safety of the first 1000 consecutive ACDF surgeries performed in their outpatient ASC, and 2) compare the safety of these outpatient ACDFs with that of consecutive ACDFs performed during the same time period in the hospital setting. METHODS A total of 1000 consecutive patients who underwent ACDF in an ACS (outpatient ACDF) and 484 consecutive patients who underwent ACDF at Vanderbilt University Hospital (inpatient ACDF) from 2006 to 2013 were included in this retrospective study of patients' medical records. Data were collected on patient demographics, comorbidities, operative details, and perioperative and 90-day morbidity. Perioperative morbidity and hospital readmission were compared between the outpatient and inpatient ACDF groups. RESULTS Of the first 1000 outpatient ACDF cases performed in the authors' ASC, 629 (62.9%) were 1-level and 365 (36.5%) were 2-level ACDFs. Mean patient age was 49.5 ± 8.6, and 484 (48.4%) were males. All patients were observed postoperatively at the ASC postanesthesia care unit (PACU) for 4 hours before being discharged home. Eight patients (0.8%) were transferred from the surgery center to the hospital postoperatively (for pain control [n = 3], chest pain and electrocardiogram changes [n = 2], intraoperative CSF leak [n = 1], postoperative hematoma [n = 1], and profound postoperative weakness and surgical reexploration [n = 1]).

    Full Text Available Multilevel cervical degenerative disc disease is well known in the cervical spine pathology, with radicular syndromes or cervical myelopathy. One or two level cervical herniated disc is common in adult and multilevel cervical degenerative disc herniation is common in the elderly, with spinal stenosis, and have the same cause: the gradual degeneration of the disc. We report the case of a patient with two level cervical disc herniation (C4 – C5 and C5 – C6 treated by anterior cervical microdiscectomy both levels and fusion at C5 – C6; after five years the patient returned with left C7 radiculopathy and MRI provided the image of a left C6 – C7 disc herniation, he underwent an anterior microsurgical discectomy with rapid relief of symptoms. Three-level cervical herniated disc are rare in adults, and the anterior microdiscectomy with or without fusion solve this pathology.

    Full Text Available Este estudo tem como objetivo avaliar a efetividade e a segurança do uso de órteses no pós-operatório de afecções degenerativas da coluna cervical. Apesar de amplamente utilizados, não existem critérios definidos para a aplicação de colares cervicais e sua relevância na artrodese cervical. Foi realizada uma revisão sistemática da literatura, além de um estudo multicêntrico controlado, composto por 32 serviços, com um total de 257 pacientes que satisfizeram os critérios de inclusão da revisão. Foram comparados desfechos clínicos e radiográficos de pacientes operados em um único nível anatômico que fizeram uso ou não de colar cervical rígido por 6 a 12 semanas após a cirurgia. As evidências disponíveis na literatura, apesar de fracas, sugerem que o uso do colar cervical diminui os escores clínicos nas primeiras semanas após o procedimento cirúrgico. Além disto, não altera a taxa de fusão quando utilizado concomitantemente à placa e aos parafusos por acesso anterior, em doenças degenerativas cervicais em um único nível anatômico.

    OBJECTIVE Beginning in 2008, the Centers for Medicare and Medicaid Service (CMS) determined that certain hospital-acquired adverse events such as surgical site infection (SSI) following spine surgery should never occur. The following year, they expanded the ruling to include deep vein thrombosis (DVT) and pulmonary embolism (PE) following total joint arthroplasty. Due to their ruling that "never events" are not the payers' responsibility, CMS insists that the costs of managing these complications be borne by hospitals and health care providers, rather than billings to health care payers for additional care required in their management. Data comparing the expected costs of such adverse events in patients undergoing spine and orthopedic surgery have not previously been reported. METHODS The California State Inpatient Database (CA-SID) from 2008 to 2009 was used for the analysis. All patients with primary procedure codes indicating anterior cervical discectomy and fusion (ACDF), posterior lumbar interbody fusion (PLIF), lumbar laminectomy (LL), total knee replacement (TKR), and total hip replacement (THR) were analyzed. Patients with diagnostic and/or treatment codes for DVT, PE, and SSI were separated from patients without these complication codes. Patients with more than 1 primary procedure code or more than 1 complication code were excluded. Median charges for treatment from primary surgery through 3 months postoperatively were calculated. RESULTS The incidence of the examined adverse events was lowest for ACDF (0.6% DVT, 0.1% PE, and 0.03% SSI) and highest for TKA (1.3% DVT, 0.3% PE, 0.6% SSI). Median inpatient charges for uncomplicated LL was $51,817, compared with $73,432 for ACDF, $143,601 for PLIF, $74,459 for THR, and $70,116 for TKR. Charges for patients with DVT ranged from $108,387 for TKR (1.5 times greater than index) to $313,536 for ACDF (4.3 times greater than index). Charges for patients with PE ranged from $127,958 for TKR (1.8 times greater than

    Objective To investigate the feasibility and advantages of slow anesthesia induced by amnesia and analgesia for anterior cervical surgery. Methods A total of 52 patients receiving surgery of anterior cervical spine were averagely divided into groups A and B before operation. Patients of Group A developed slow anesthesia induced by amnesia and analgesi-a through endotracheal intubation, and those of group B underwent quick induction of anesthesia through tracheal intubation. The cough response during tracheal intubation and the tolerance of incubating conditions were recorded respectively. At the same time, the postoperative impression of tracheal intubation was followed up. Results Both group A and B had successful operation procedures. The patients in group A were intubated without changing the head positions; their own muscle tension effectively protected the cervical spine; and the patients were well tolerant to intubation after surgery. Whereas, the patients of group B had to have their cervical spine well-protected by others, and were not tolerant to intubation removal. In this group, 19 cases had restlessness during intubation taking-off and drug had to be applied for intubation tolerance. Conclusion Slow anesthesia induced by amnesia and analgesia is a simple, convenient and practical approach for anterior cervical surgery, which can effectively protect the cervical spine and patients well tolerate intubation.%目的 探讨健忘镇痛慢诱导用于颈椎前路手术的可行性和优势.方法 将52例颈椎前路手术患者平均分为2组:A组行健忘镇痛慢诱导气管插管全麻,B组行快诱导气管插管全麻.分别记录患者气管插管过程中的呛咳反应、带气管插管患者耐管情况,随访患者术后对气管插管的印象.结果 A组和B组都顺利完成手术,A组患者插管不改变头位,在自身肌张力保护下插管,有效保护颈椎病变部位,且术后能很好耐受带管.B组插管时令专人保护颈椎,

    Few reports have described the combined use of unilateral pedicle screw fixation and interbody fusion for lumbar stenosis. We retrospectively reviewed 79 patients with lumbar stenosis. The rationale and effectiveness of unilateral pedicle screw fixation were studied from biomechanical and clinical perspectives, aiming to reduce stiffness of the implant. All patients were operated with posterior interbody fusion using a diagonal cage in combination with unilateral transpedicular screw fixation and had reached the 3-year follow-up interval after operation. The mean operating time was 115 minutes (range=95-150 min) and the mean estimated blood loss was 150 mL (range=100-200 mL). The mean duration of hospital stay was 10 days (range=7-15 days). Clinical outcomes were assessed prior to surgery and reassessed at intervals using Denis' pain and work scales. Fusion status was determined from X-rays and CT scans. At the final follow-up, the clinical results were satisfactory and patients showed significantly improved scores (pdiagonal cage with unilateral transpedicular fixation is an effective treatment for decompressive surgery for lumbar stenosis.

    OBJECTIVE Heterotopic ossification (HO) has been reported following total hip, knee, cervical, and lumbar arthroplasty, as well as following posterolateral lumbar fusion using recombinant human bone morphogenetic protein-2 (rhBMP-2). Data regarding HO following anterior cervical discectomy and fusion (ACDF) with rhBMP-2 are sparse. A subanalysis was done of the prospective, multicenter, investigational device exemption trial that compared rhBMP-2 on an absorbable collagen sponge (ACS) versus allograft in ACDF for patients with symptomatic single-level cervical degenerative disc disease. METHODS To assess differences in types of HO observed in the treatment groups and effects of HO on functional and efficacy outcomes, clinical outcomes from previous disc replacement studies were compared between patients who received rhBMP-2/ACS versus allograft. Rate, location, grade, and size of ossifications were assessed preoperatively and at 24 months, and correlated with clinical outcomes. RESULTS Heterotopic ossification was primarily anterior in both groups. Preoperatively in both groups, and including osteophytes in the target regions, HO rates were high at 40.9% and 36.9% for the rhBMP-2/ACS and allograft groups, respectively (p = 0.350). At 24 months, the rate of HO in the rhBMP-2/ACS group was higher than in the allograft group (78.6% vs 59.2%, respectively; p disc spaces significantly reduced range of motion, more so in the rhBMP-2/ACS group. At 24 months, HO negatively affected Neck Disability Index scores (excluding neck/arm pain scores), neurological status, and overall success in patients in the rhBMP-2/ACS group, but not in patients in the allograft group. CONCLUSIONS Implantation of rhBMP-2/ACS at 1.5 mg/ml with polyetheretherketone spacer and titanium plate is effective in inducing fusion and improving pain and function in patients undergoing ACDF for symptomatic single-level cervical degenerative disc disease. At 24 months, the rate and dimensions (length and

    Objective To investigate the incidence and causes of non-fusion segment disease ( NFSD ), both adjacent and non-adjacent to the fused segment, after the anterior cervical arthrodesis.Methods This is a retrospective cohort study. Between January 1998 and January 2011, 171 patients who had anterior cervical decompression and fusion for the intervertebral disc herniation and cervical spondylosis were followed clinically. There were 97 males and 74 females, and the average age at the operation was ( 51.90 ± 9.28 ) years ( range: 31 - 72 years ). We evaluated the correlation between the incidence of symptomatic non-fusion segment disease and the following clinical parameters ( age at the operation, fusion levels ) and radiological parameters ( preoperative and postoperative cervical spine alignment, Pavlov’s ratio at the C5 level, and preoperative existence of a non-fusion segment degeneration on magnetic resonance imaging ).Results Of the 171 patients reviewed, 16 patients had non-fusion segment disease ( 9.36% ), 12 patients had adjacent segment disease and 4 had non-adjacent segment disease. Postoperative cervical lordosis in the non-fusion segment disease group was signiifcantly smaller than that of the disease-free group [ ( 7.38 ± 12.37 ) ° vs. ( 17.26 ± 9.75 ) °,P < 0.001 ]. Fusion levels in the NFSD group were 1.63 whereas 2.27 in disease-free group (P = 0.002 ). The incidence of disc degeneration in non-fused segments was more severe in the NFSD group than in the disease-free group [ ( 2.63 ± 0.62 )vs. ( 1.62 ± 0.99 ), P = 0.008 ].Conclusions The incidence of symptomatic non-fusion segment disease after the anterior cervical arthrodesis has multifactorial causes. Postoperative cervical lordosis, disc degeneration in non-fusion segments, and the number of fusion levels are all factors in the incidence of NFSD.%目的:探讨颈椎前路减压融合术后非融合节段病变( non-fusion segment disease,NFSD )的发生率和

    Objective To discuss the application effect of nano-hydroxyapatite and polyamide composite (n-HA/PA66) in anterior cervical subtotal corpectomy and fusion with plate for the treatment of cervical spondylotic myelopathy. Methods Thirty patients with cervical spondylotic myelopathy were treated with anterior cervical subtotal corpectomy, in which n-HA/PA66 was grafted and platted for the decompression and fusion. The clinical results and graft fusion were evaluated after the operation. Results All patients were operated successfully and followed up for 9 to 17 months with an average of 12.6 months. The neurological symptoms and signs of patients were greatly improved. There was no allergic and toxic reactions induced by n-HA/PA66 implantation. Imaging studies showed that cervical alignments and intervertebral height were well maintained, and graft fusions were achieved in all cases 6 to 8 months after operation. However, there were heterotopic ossifications of different degrees in the posterior edge of n-HA/PA66 artificial vertebral body. Conclusions n-HA/PA66 artificial vertebral body has good fusion rate, and could effectively maintain the biological alignment and cervical intervertebrai height. The long-term effects depend on further follow-up.%目的 探讨纳米羟基磷灰石/聚酰胺(n-HA/PA66)在脊髓型颈椎病椎体次全切减压融合术中的应用效果.方法 对30例脊髓型颈椎病患者均行颈椎前路椎体次全切n-HA/PA66植入钛板内固定术,对其疗效及融合情况进行评价.结果 30例患者均成功完成手术并获得随访,随访时间9~17个月,平均12.6个月.所有患者神经症状均明显改善,植入物未引起过敏及毒性反应,颈椎生理曲度、椎间高度有良好的恢复和维持,术后6~8个月时获得植骨融合,n-HA/PA66人工椎体后缘存在不同程度的异位骨化.结论 n-HA/PA66人工椎体作为颈椎前路手术植骨材料融合率高,可以有效保持颈椎生理曲度及椎

    Objective To study adjacent level degeneration after anterior cervical spine fusion with a plate and its relation to the plate position.Methods Totally 165 patients were received anterior cervical spine fusion with plates months, who had a bony fusion wholly.The cephalad and caudal plate to disc distance(PDD) was measured on thepostoperative lateral radiograph and was used to divide the patients into two groups. In group A the PDD was<5mm, and in group B it was>5mm. The severity of the ossification at the two adjacent disc space was classified on a scale ranging from grade 0(no ossification ) to grade 2(complete bridging ). Preoperative, immediate postoperative and 6 to 46 months follow-up radiographs were taken, measured the height of cephalad and caudal adjacent intervertebral and adjacent vertebral body, and then calculated the ratio of intervertebral height to vertebral body height (R), besides, calculated the angle(α)of upper and down endplate gradient of two adjacent disc. Results In cephalad adjacent disc, group A had 53.7% levels developed ossification and 29.8% in group B; compared to caudal adjacent disc, group A and B was 38.5% and 19.7%, respectively. The rate of ossification was higher in group A than in group B, both at two adjacent disc (P<0.05). There was no significant difference between preoperative and postoperative both R ratio and angle α in group A of cephalad adjacent disc (P>0.05), but it was significant decreased when followed up comparing to preoperative and postoperative (P<0.05). The result of R ratio of caudal adjacent disc was similar with cephalad adjacent disc in group A, but angle α was not. There was no significant difference among preoperative, postoperative and following up time both R ratio and angle α in group B of cephalad and caudal adjacent disc (P>0.05).Conclusion Adjacent segments degeneration was one of the common complications after anterior cervical spine fusion. The incidence could be affected

    Posterior lumbar interbody fusion (PLIF) using threaded cages has gained wide popularity for lumbosacral spinal disease. Our biomechanical tests showed that PLIF using a single diagonal cage with unilateral facetectomy does add a little to spinal stability and provides equal or even higher postoperative stability than PLIF using two posterior cages with bilateral facetectomy. Studies also demonstrated that cages placed using a posterior approach did not cause the same increase in spinal stiffness seen with pedicle screw instrumentation, and we concluded that cages should not be used posteriorly without other forms of fixation. On the other hand, placement of two cages using a posterior approach does have the disadvantage of risk to the bilateral nerve roots. We therefore performed a prospective study to determine whether PLIF can be accomplished by utilizing a single diagonal fusion cage with the application of supplemental transpedicular screw/rod instrumentation. Twenty-seven patients underwent a PLIF using one single fusion cage (BAK, Sulzer Spine-Tech, Minneapolis, MN, USA) inserted posterolaterally and oriented anteromedially on the symptomatic side with unilateral facetectomy and at the same level supplemental fixation with a transpedicular screw/rod system. The internal fixation systems included 12 SOCON spinal systems (Aesculap AG, Germany) and 15 TSRH spinal systems (Medtronic Sofamor Danek, USA). The inclusion criteria were grade 1 to 2 lumbar isthmic spondylolisthesis, lumbar degenerative spondylolisthesis, and recurrent lumbar disc herniations with instability. Patients had at least 1 year of low back pain and/or unilateral sciatica and a severely restricted functional ability in individuals aged 28-55 years.

    2005-07-01

    Late-onset vertebral body (VB) fracture after lumbar transpedicular fixation has not been previously described in the literature. The authors present three cases in which VB fracture occurred several months after posterolateral fixation in patients with degenerative disease or traumatic injury. The authors suggest that postoperative osteopenia, modified load-sharing function, and intravertebral clefts were responsible for the fractures. Two women and one man were evaluated at a mean follow-up interval of 3 months. Two patients suffered recurrent lumbar pain. Radiography and magnetic resonance imaging revealed fracture of some of the instrumentation-treated VBs. These two patients underwent surgical superior or inferior extension of instrumentation. The third, an asymptomatic patient, received conservative management. The two patients who underwent reoperation made complete recoveries, and there was no evidence of further bone collapse in any case. The authors speculate that alterations in the VBs may occur following application of spinal instrumentation. In rare cases, the device can fracture and consequently lead to recurrent lumbar back pain. Recovery can be achieved by extending the instrumentation in the appropriate direction.

  6. Degenerative cervical myelopathy.

    Science.gov (United States)

    Kato, So; Fehlings, Michael

    2016-09-01

    Cervical myelopathy is the most common cause of acquired spinal cord compromise. The concept of degenerative cervical myelopathy (DCM), defined as symptomatic myelopathy associated with degenerative arthropathic changes in the spine axis, is being introduced. Given its progressive nature, treatment options have to be chosen in a timely manner. Surgical options include anterior discectomy and fusion (ACDF), anterior corpectomy and fusion (ACCF), arthroplasty (in highly select cases), posterior laminectomy with/without fusion, and laminoplasty. Indications for each should be carefully considered in individual patients. Riluzole, a sodium-glutamate antagonist, is a promising option to optimize neurologic outcomes post-surgery and is being examined in the CSM-Protect Randomized Controlled Trial. Preoperative risk assessment is mandatory for prognostication. Sagittal alignment is known to play an important role to optimize surgical outcome. Guidelines for optimal management of DCM are in process. In principle, all but the mildest cases of DCM should be offered surgery for optimal outcome. PMID:27250040

    Background Lower cervical dislocation with locked facets is common in cervical injury. The locked facets include unilateral and bilateral types. Different successful closed reduction rates has been achieved between unilateral and bilateral types by using rapid skull traction, which was commonly used to reduce the cervical dislocation. It is important to investigate a suitable management specific to patients with different types of cervical locked facets.Methods A total of 38 patients with cervical dislocation with locked facet due to cervical injury treated by rapid skull traction and operation from 1988 to 2005 were reviewed. Rapid skull traction was used in all the patients. Successful closed reduction rate was 88.0% in patients with bilateral cervical locked facets and that was 15.4% in those with unilateral cervical locked facets. These data were then statistically compared by Chi-square test. Patients who were reduced successfully underwent anterior cervical discectomy and fusion at the injured level, and those who failed in closed reduction received posterior open reduction and fixation.Results In this series, there was statistically significant difference (P<0.05) in the rate of successful closed skull traction reduction between unilateral and bilateral locked facets dislocation. Unilateral cervical locked facets dislocation was not easily reduced by skull traction which was suitable for reduction of bilateral cervical locked facets dislocation. However,unilateral cervical locked facets dislocation can be reduced by posterior open reduction.Conclusions Unilateral cervical locked facets dislocation should be treated immediately with posterior open reduction and instrumentation. Bilateral cervical locked facets dislocation can be reduced by rapid skull traction firstly and anterior cervical discectomy and interbody fusion later.

    Full Text Available Lutz Weise, Olaf Suess, Thomas Picht, Theodoros KombosNeurochirurgische Klinik, Charité – Universitätsmedizin Berlin, Berlin, GermanyObjective: Transpedicular screws are commonly and successfully used for posterior fixation in spinal instability, but their insertion remains challenging. Even using navigation techniques, there is a misplacement rate of up to 11%. The aim of this study was to assess the accuracy of a novel pedicle screw system.Methods: Thoracic and lumbar fusions were performed on 67 consecutive patients for tumor, trauma, degenerative disease or infection. A total of 326 pedicular screws were placed using a novel wire-guided, cannulated, polyaxial screw system (XIA Precision®, Stryker. The accuracy of placement was assessed post operatively by CT scan, and the patients were followed-up clinically for a mean of 16 months.Results: The total medio-caudal pedicle wall perforation rate was 9.2% (30/326. In 19 of these 30 cases a cortical breakthrough of less than 2 mm occurred. The misplacement rate (defined as a perforation of 2 mm or more was 3.37% (11/326. Three of these 11 screws needed surgical revision due to neurological symptoms or CSF leakage. There have been no screw breakages or dislocations over the follow up-period.Conclusion: We conclude that the use of this cannulated screw system for the placement of pedicle screws in the thoracic and lumbar spine is accurate and safe. The advantages of this technique include easy handling without a time-consuming set up. Considering the incidence of long-term screw breakage, further investigation with a longer follow-up period is necessary.Keywords: spinal instrumentation, pedicle screws, misplacement, pedicle wall perforation

  11. Comparison of the safety of three methods of lumbar transpedicular screw fixation

    Objective: To choose a proper method of lumbar transpedicular screw fixation at different lumbar levels among the three methods ( Roy-Camille's method, Magerl's method and Du's method) in the Chinese population.Methods: Three-dimensional ( 3-D ) images were reconstructed with image data of 42 adult lumbar segments that were scanned by Electron Beam CT. The three methods of lumbar pedicle screw fixation were simulated on the 3-D reconstructed images and the parameters of implanting pedicle screws were measured.Results: There was statistically significant difference at the distance from the entrance point to the pedicle axis between the three methods (P < 0. 001). The distances measured by Du's method were shortest from L1 to L4,and the distances measured by Magerl's method were shortest at L5 (P < 0.05). There was no significant difference from L1 to L2 (P > 0.05) but significant difference from L3 to L5 at inserting safe ranges of TSA (transverse section angle) was found between the three methods (P <0.05). From L3 to L4, the inserting safe ranges of TSA measured by Du's and Magerl's methods were significantly larger than that measured by Roy-Camille's method (P <0.05), but there was no significant difference between them (P > 0.05). At L5, the inserting safe ranges of TSA measured by Magerl's method were largest among the three methods (P < 0.05).Conclusions: Among the three methods, Du's method is the best choice from L1 to LA because its distance from the entrance point to the pedicle axis is shortest and the safe range of TSA is largest; Magerl's method can be used from L3 to L5 and is the best choice at L5; Roy-Camille's method is applicable at L1 and L2.

    INTRODUCTION Cervical kyphosis is a progressive cervical sagittal plane deformity that may cause a reduction in the ability to look horizontally, breathing and swallowing difficulties, sense of thoracic oppression and social isolation. Moreover, cervical kyphosis can cause myelopathy due to a direct compression by osteo-articular structures on the spinal cord or to a transitory ischaemic injury. The treatment of choice is surgery. The goals of surgery are: nervous structures decompression, cervical and global sagittal balance correction and vertebral stabilization and fusion. PRESENTATION OF CASE In October 2008 a 35 years old woman underwent surgical removal of a cervical-bulbar ependymoma with C1–C5 laminectomy and a C2–C5 laminoplasty. Five months after surgery, the patient developed a kyphotic posture, with intense neck and scapular girdle pain. The patients had a flexible cervical kyphosis. Therefore, we decided to perform an anterior surgical approach. We performed a corpectomy C4–C5 in order to achieve the anterior decompression; we placed a titanium expansion mesh. DISCUSSION Cervical kyphosis can be flexible or fixed. Some authors have reported the use of anterior surgery only for flexible cervical kyphosis as discectomy and corpectomy. This approach is useful for anterior column load sharing however it is not required for deformity correction. CONCLUSION The anterior approach is a good surgical option in flexible cervical kyphosis. It is of primary importance the sagittal alignment of the cervical spine in order to decompress the nervous structures and to guarantee a long-term stability. PMID:25462050

    Objective:To explore the early clinical effects of cervical anterior hybrid technique using anterior corpectomy and fusion (ACF) combined with cervical artificial disc replacement (C-ADR) for multilevel spondylotic myelopathy.Method: Hybrid technique was applied in 24 cases of multilevel cervical spondylotic myelopathy (group A), and 28 patients were treated by the traditional anterior noncontiguous decompression and fusion (group B) between Oct 2008 and Jun 2009. Clinical results were evaluated by JOA score preoper-atively and postoperatively at 3d,3 months, 12 months,and 24 months.The operative time and blood loss were recorded.The range of movement (ROM) in replaced segment and C2-7 of all cases were evaluated by radiograph (X-rays of bending,extending).CT or MRI scan was applied postoperatively to find out the pressure of the spine and heterotopic ossification in the replaced segment.Result: There was no serious complication.Improvement in all cases occurred obviously, and JOA score increased (P0.05).The mean C2-7 ROM of both groups did not recover to the preoperative value,but group A showed faster and better C2-7 ROM recovery. Replaced segment achieved stability and restored partial of ROM.There was no prosthesis subsidence or ex-cursion.No hetertopic ossification was found in the replaced level,and the movement had no significant difference (P>0.05) between preoperative and postoperative at two years post-operation.But the deteriorated adjacent level of 2 cases were found in group B.Conclusion:In term of surgical time,blood loss and restoring stabilityand partial motion of the C2-7 ROM,the anterior hybrid technique is superior compared with the traditional anterior noncontiguous decompression and fusion.At the same time,less compensatory motion occurs at the adjacent segments,and less ASD will result.%目的:探讨颈椎前路减压后行融合与人工椎间盘置换联合手术治疗多节段脊髓型颈椎病的临床疗效.方法:2008年10月~2009年6

    Cervical arthroplasty after anterior decompression with insertion of a prosthetic total disc replacement has been suggested as an alternate to anterior cervical fusion. It develops quickly during recent years. Currently there are several cervical arthroplasty devices. Each device varies in terms of materials, range of motion and constraint. Early studies suggest that in the short term, the complication rate and efficacy is no worse than fusion surgery. Long-term results have not yet been reported. This review examines the current prostheses as well as discussing issues regarding indications and technique. It is hoped that an improvement of cervical arthroplasty occurs in terms of materials and design as spinal surgeons enter a new dines of the management of cervical spine disease.

[Methods] From 1986.1 to 1999. 12, a total of 346 patients with cervical degenerative disease underwent the surgery of enlarged decompression with circular saw and auto iliac bone grafting. Among them there were 1 segment in 55 patients, 2 segments in 223 patients and 3 segments in 68 patients. The two motion segments adjacent to the fused segment and interval from the fused segment were evaluated respectively for imaging changes and divided the results into groups for statistical test. [Results] The patients were followed up for 13. 5 (4.1 ~ 18) years on average. Total 156 cases (45. 1% ) had obvious adjacent segment degeneration, 23 cases (6. 6% ) had obvious interval segment degeneration. The interval segment degeneration was less than that of adjacent segment degeneration, and the comparative differences had statistically significance (P 0.05 ) .

    Keegan (1965) reported a patient who presented with "dissociated motor loss," an acute paralysis of the upper extremity with minimal sensory signs and no long tract signs, and documented an anterior root lesion following autopsy. Sobue et al. (1975) reported similar cases using the term "cervical spondylotic amyotrophy (CSA)," but postulated pathology of the anterior horn. Although Keegan's "dissociated motor loss" surely referred to isolated motor paresis with no or minimal sensory signs, contrary to existing criticism, a more general term, CSA, should be preferred. CSA is divided into proximal and distal types. Distal CSA often presents with a drop finger, and thus may be misdiagnosed as posterior interosseous nerve palsy. Documentation of the involvement of ulnar muscles by clinical signs and EMG would lead to the diagnosis of distal CSA. Proximal CSA may be confused with neuralgic amyotrophy (NA), although the sparing of the serratus anterior and the stereotypic involvement of deltoid, infraspinatus, biceps brachii, and brachioradialis suggest CSA. Cervical MRI is not diagnostic in around half of CSA cases, and denervation in paraspinal EMG is a more sensitive test that can exclude NA. Amyotrophic lateral sclerosis is another important differential diagnosis for CSA. PMID:27156504

    Full Text Available Introduction: The vertebral artery is unique among the cervico-cephalic vessels by virtue of its position and relationship to the adjacent structures. The advent of new techniques and materials for surgical treatment of lower cervical spinal condition has come along with possible potential complications. As vertebral artery normally passes through transverse foramen of sixth cervical vertebra, these procedures can safely be done on seventh cervical vertebra. Aim: To study the anatomical variation of vertebral artery entering the transverse foramen of cervical vertebrae. Material & Methods: 50 vertebral arteries were dissected in 25 embalmed cadavers, out of which 19 cadavers were male and 6 were female. Vertebral artery was dissected from its origin to its entry into foramen magnum. Results: 4 (8 % cases were found where vertebral artery entered into transverse foramen of 7th cervical vertebrae out of which 1 was bilateral, and 2 was on left side. In 46 cases (92% it entered through transverse foramen of 6th cervical vertebrae. Conclusion: In 8% cases as vertebral artery enters through C7 transverse foramina, the relation is important while performing transpedicular fixation or other spinal surgeries.

    Instrumentation of the cervical spine enhances stability and improves arthrodesis rates in children undergoing surgery for deformity or instability. Various morphologic and clinical studies have been conducted in children, confirming the feasibility of anterior or posterior instrumentation of the cervical spine with modern implants. Knowledge of the relevant spine anatomy and preoperative imaging studies can aid the clinician in understanding the pitfalls of instrumentation for each patient. Preoperative planning, intraoperative positioning, and adherence to strict surgical techniques are required given the small size of children. Instrumentation options include anterior plating, occipital plating, and a variety of posterior screw techniques. Complications related to screw malposition include injury to the vertebral artery, neurologic injury, and instrumentation failure. PMID:27097300

    2012-02-01

    The surgical treatment of cervical spondylosis and resulting cervical radiculopathy or myelopathy has evolved over the past century. Surgical options for dorsal decompression of the cervical spine includes the traditional laminectomy and laminoplasty, first described in Asia in the 1970\\'s. More recently the dorsal approch has been explored in terms of minimally invasive options including foraminotomies for nerve root descompression. Ventral decompression and fusion techniques are also described in the article, including traditional anterior cervical discectomy and fusion, strut grafting and cervical disc arthroplasty. Overall, the outcome from surgery is determined by choosing the correct surgery for the correct patient and pathology and this is what we hope to explain in this brief review.

    Objective To explore the clinical efficacy of transpedicular intracorporeal grafting combined with posterior short-segment pedicle screw via the injured vertebra for thoracolumbar fractures treatment. Methods A total of 52 patients of thoracolumbar fractures were treated with transpedicular intracorporeal grafting combined with posterior short-segment pedicle screw via the injured vertebra from June 2006 to December 2009. According to the AO classification, all of them are type A fracture. Preoperative, postoperative and follow-up X-ray were performed for evaluating anterior heights of the injured vertebra(AHIV) and Cobb's angle, as well, preoperative and postoperative CT scans were taken to measure the sagittal canal diameter(SCD). Postoperative complications and neurofunctional recovery of the spinal cord were evaluated. Results All cases were followed up about 12 to 30 months, averagely 16.5±7.8 months. There was no infection of incision and no aggravation of spinal cord function. There was no implant failure and no loss of spinal curvatures. After surgery and at final follow-up, anterior heights of the injured vertebra showed good recovery, and Cobb's angel appeared smaller.

    The rheumatoid involvement of the cervical spine can be divided into three phases. In the early stage of the disease there is an isolated atlantoaxial subluxation (AAS), followed by vertical instability and subaxial instability. If patients show clear symptoms of cervical myelopathy, which can occur during any stage of the disease, the progression cannot be stopped by conservative treatment, which is of great importance at the beginning of the cervical manifestation. Patient education, physiotherapy and immobilization with a stiff collar can significantly reduce pain. Early and effective DMARD therapy can have a positive effect on the natural history of the disease. In case of progressive instability, cervical myelopathy or severe pain operative treatment is indicated. If there is an isolated AAS, fusion can be restricted to the C1/C2 segment. The Magerl transarticular screw fixation is the preferred technique for stabilization. If there is evidence for vertical instability or severe destruction of the C0/C1 joints, occipital cervical fusion has to be performed. Durin the preoperative planning it is necessary to look for signs of subaxial instability. If this is the case, fusion should include the entire cervical spine. Transoral decompression may be necessary when there is persistent anterior compression of the myelon, typically seen in fixed AAS. Non-ambulatory myelopathic patients are more likely to develop severe surgical complications. Therefore, it is important to avoid the development of severe cervical instability by early surgical intervention. The right timing for surgery is still a matter of controversy. Future prospective randomized trials should address this topic to improve the treatment concept for the rheumatoid patient.

    We present a case of a 47-year-old-woman with a complaint of cervical pain with paresthetic appearance on her left arm. She was treated with analgetics. Further radiological evaluation because of the persistent pain revealed an osteolytic destruction of the fourth cervical vertebra. The patient underwent anterior cervical corpectomy with total excision of the tumor. Stabilization of the cervical spine was performed. Histology confirmed the diagnosis of Langerhans cell histiocytosis (LCH) of the cervical spine. This case report presents the histopathological evaluation, diagnostic work-up and the treatment procedures because of rarity of cervical spinal LCH cases in the literature. PMID:20669118

    In the acute setting, accurate radiological interpretation of paediatric cervical spine trauma can be difficult due to a combination of normal variants and presence of multiple synchondroses. We present a rare case of a fracture through the anterior atlantal synchondrosis in a paediatric spine. A five-year-old boy, who fell backwards onto the top of his head while swinging across on a monkey bar frame, presented with neck pain, cervical muscle spasm and decreased right lateral rotation and extension of his neck. Computed tomography showed a displaced diastatic fracture through right anterior atlantal synchondrosis. There are only 12 cases of paediatric C1 fractures reported in the world literature. The importance of considering this diagnosis in the appropriate clinical setting, and the normal variants in the paediatric atlas that can cause diagnostic dilemma to the interpreting radiologist, are discussed in this case report.

    Full Text Available Objective: The most common used technique for posterolateral cervical disc herniations is anterior approach. However, posterior cervical laminotoforaminomy can provide excellent results in appropriately selected patients with foraminal stenosis in either soft disc prolapse or cervical spondylosis. The purpose of this study was to present the clinical outcomes following posterior laminoforaminotomy in patients with radiculopathy. Materials and Methods: We retrospectively evaluated 35 patients diagnosed with posterolateral cervical disc herniation and cervical spondylosis with foraminal stenosis causing radiculopathy operated by the posterior cervical keyhole laminoforaminotomy between the years 2010 and 2015. Results: The file records and the radiographic images of the 35 patients were assessed retrospectively. The mean age was 46.4 years (range: 34-66 years. Of the patients, 19 were males and 16 were females. In all of the patients, the neurologic deficit observed was radiculopathy. The posterolaterally localized disc herniations and the osteophytic structures were on the left side in 18 cases and on the right in 17 cases. In 10 of the patients, the disc level was at C5-6, in 18 at C6-7, in 2 at C3-4, in 2 at C4-5, in 1 at C7-T1, in 1 patient at both C5-6 and C6-7, and in 1 at both C4-5 and C5-6. In 14 of these 35 patients, both osteophytic structures and protruded disc herniation were present. Intervertebral foramen stenosis was present in all of the patients with osteophytes. Postoperatively, in 31 patients the complaints were relieved completely and four patients had complaints of neck pain and paresthesia radiating to the arm (the success of operation was 88.5%. On control examinations, there was no finding of instability or cervical kyphosis. Conclusion: Posterior cervical laminoforaminotomy is an alternative appropriate choice in both cervical soft disc herniations and cervical stenosis.

    Objectives To evaluate clinical effect of multilevel cervical spondylotic myelopathy( CSM) treated by an-terior vertebral subtotal resection conjugated with intervertebral space decompression and bone graft fusion. Methods Forty-six cases of CSM whose three segments were received anterior approach treatment. Among them, 24 cases re-ceived vertebral subtotal resection conjugated with single cell gap decompression and bone graft fusion as Group A, and the other 22 cases were given subtotal resection decompression of two vertebral bodies and decompression and bone graft fusion as Group B. Operation time and bleeding, bone graft fusion rate, nerve function amelioration and cervical vertebra physiological curvature restoration were observed and compared. Results All patients were followed up for 15~36 months. Operation time in Group A was (105 ± 20) min, while that in Group B was (180 ± 30) min, bleeding during operation were (120 ± 35) ml in group A and (210 ± 25) ml in group B, the difference of the data between two groups were statistically significant ( P0. 05). Postopera-tion cervical vertebra physiological curvature of both groups were obviously ameliorated, without statistical significance (P>0. 05). Conclusions Multilevel CSM treatment by anterior vertebral subtotal resection conjugated with interver-tebral space decompression and bone graft fusion can gain satisfactory effect, with advantages such as relatively simp-ler operations, less bleeding, shorter operation time, higher bone graft fusion rates, and so on. It is a safe, effective operation method which can also reduce complications.%目的:评价前路椎体次全切除结合椎间隙减压植骨融合术治疗多节段脊髓型颈椎病( CSM )的临床疗效。方法采用前路手术治疗累及3个节段的CSM患者46例。其中24例行椎体次全切除+单间隙减压植骨融合术( A组);22例行2个椎体次全切除减压植骨融合术( B组)。观察比较两组手术时间、术中

    2014-10-01

    Cervical radiculopathy is a common cause of pain in the arm. It is caused by nerve root compression in the neck, as a consequence of a herniated disc, or spondyliotic foraminal stenosis. It causes severe pain, especially during the first few weeks, and paraesthesias in the forearm and hand. Patients also suffer from neck pain and loss of strength in the relevant arm. The arm pain can be exacerbated by certain movements of the head; these should be avoided as much as possible. Diagnosis can be made on the basis of history and physical examination. The pain generally disappears without active patient treatment. A semi-rigid cervical collar is recommended to accelerate pain relief. In cases of persistent pain, surgery will be considered. In such cases an MRI should be performed to show the cause and level of nerve root compression. PMID:26185991

    In the surgical management of cervical spondylosis, the application of rigid internal fixation can enhance the immediate stability of the cervical spine. The sophistication of such internal fixation systems and the indications for their use are continuously evolving. A sound understanding of regional anatomy, biomechanics, and kinematics within the cervical spine is essential for the safe and effective application of internal fixation. Numerous options currently exist for anterior cervical plating systems; some lock the screws to the plate rigidly (constrained), whereas others allow for some rotational or translational motion between the screw and plate (semiconstrained). The role of anterior fixation in single and multilevel fusions is still the subject of some controversy. Long anterior cervical reconstructions may require additional posterior fixation to reliably promote fusion. Rigid fixation in the posterior cervical spine can be achieved with lateral mass screws or pedicle screws. Although lateral mass screws provide excellent fixation within the subaxial cervical spine, the regional anatomy of C2 and C7 often make it difficult to place such screws, and pedicle screws at these levels are advocated. Pedicle screws achieve fixation into both the anterior and posterior column and are arguably the most stable form of rigid internal fixation within the cervical spine. Familiarity with these internal fixation techniques can be an extremely valuable tool for the spine surgeon managing these degenerative disorders of the cervical spine.

    Objective To evaluate the outcome of open-door laminoplasty for the treatment of failed anterior cervical spine surgery. Methods From February 2003 to June 2009, 15 patients underwent opendoor laminoplasty for the failed anterior cervical spine surgery. The causes of revision and the progression of disease were analyzed. Japanese Orthopedic Association (JOA)scores and Nurick grade were adopted to record the improvement of neurological status and walking ability. Results Two patients were excluded for analysis because of lost follow-up and follow-up less than 12 months. The mean follow-up period after revision surgery for the other 13 patients was 26 months (ranged 13-52 months). The mean interval between the initial and revision surgery was 24 months ( ranged 5 months to 6 years). The causes of revision were as following: degeneration of the adjacent segment in 2 cases, inadequate decompression in 5 cases, misdiagnosis of ossification of posterior longitudinal ligament(OPLL) as myelopathy in 4 cases, and progression of OPLL in 2 cases. Posterior laminoplasty was recommended for each patient. After the operation,13 patients improved neurologically with respect to JOA score, 12 patients improved their walking ability while 1 remained unchanged. The mean modified JOA scores improved from 10. 5 to 13.8 ( P < 0. 05 ), the average recovery rate was 53.0% after the revision operation. The mean overall Nurick grade was 3.1 preoperatively and 1.9 at the final follow-up ( P < 0.05 ), the mean improvement of the Nurick grade was 1. 2. Complications included cerebrospinal fluid leakage in 1 case, new axial neck pain in 1 case, and transient C5 nerve root palsy in 1 case. Conclusions Open-door laminoplasty is a straightforward and effective treatment for failed anterior cervical spine surgery due to inadequate decompression, progressive OPLL or degeneration of the adjacent segment. The merit of the open-door laminoplasty for failed anterior spine fusion is able to avoid

    Full Text Available Background: Evaluation of result of anterior cervical approach with manubriotomy and anterior instrumentation in tuberculosis of cervicothoracic spine in terms of the neurological recovery, reconstruction of spine and prevention of deformity along with relief of pain. Materials and Methods: All five patients with cervicothoracic caries spine had surgery through anterior cervical approach with manubriotomy in our hospital and underwent excision of the involved vertebrae and intervertebral discs followed by anterior spinal reconstruction with titanium spacer cage filled with cancellous iliac crest bone graft and Orion plate with locking screw. Antitubercular drugs were administered for 12 months. The follow-up period ranged from 12 to 36 months. Results: Analysis of result was done on the basis of clinical and radiological criteria. Clinical assessment based on Frankel grade and modified JOA score showed significant improvement from preoperative findings. Radiological assessment showed osteointegration, no spinal instability and no progression of the deformity. The pain control, based on visual analog scale changed from a pre-operative average of 7.5 to 2 at the last follow-up thereby indicating significant improvement and all patients returned to preoperative functional status. One patient had transient hoarseness of voice. No other complication had been encountered in the immediate post operative and during the follow-up period. Conclusions: Our study showed that anterior cervical approach with manubriotomy and anterior insertion of titanium cage, filled with autogenous bone graft, secured with locking plate instrumentation has a successful role in the eradication of infection, neurological recovery, segmental spinal reconstruction and it also reduces surgical time, blood loss, and surgical complications and approach related comorbidity in follow up period.

    The aim of this study was to describe the method and the value of cervical discography as correlated with the MR findings. Twenty-one discs in 11 consecutive patients who underwent cervical discography were analyzed. MR and CT discography (CTD) were performed in all patients. Discography was performed after swallowing barium for visualizing the pharynx and the esophagus to prevent penetration. We also analyzed the preceding causes of the subjects' cervical pain. The results of the pain provocation test were classified into concordant pain, discordant pain and a negative test. MRI was analyzed according to the T2-signal intensity (SI) of the disc, disc height, annular bulging and disc herniation. The CTD was analyzed for degeneration or radial tear of the disc, epidural leakage of the contrast agent and pooling of the contrast agent at the periphery of the disc. The pain provocation tests were correlated with the MR and CTD findings. We used the chi-square test to analyze the results. Concordant pain was observed in 14 cases, discordant pain in 3 cases and there were negative tests in 4 cases. There were no complications related to the procedure. Four patients had undergone anterior cervical fusion and four patients that developed after traffic injuries. The decreased T2-SI and annular bulging on MRI, disc degeneration and peripheral pooling of the contrast agent on CT were significantly correlated with pain provocation. When the diagnosis of disc disease is difficult with performing MRI, cervical discography with using swallowed barium solution to reduce the penetration of the esophagus or hypopharynx may play be helpful. The decreased T2-SI and annular bulging on MRI correlated significantly with a positive result on the pain provocation test.

    Full Text Available O aumento da utilização de novas técnicas e materiais de síntese para o tratamento cirúrgico de afecções da coluna cervical baixa foi acompanhado da crescente preocupação em relação às complicações que podem ocorrer. A técnica de fixação transpedicular, amplamente utilizada para os outros níveis da coluna vertebral, quando realizada na coluna cervical, apesar de conferir maior estabilidade quando comparada a outras técnicas, pode cursar com complicações graves como lesão da artéria vertebral, lesão de raiz nervosa, além de lesão da articulação facetária. A vértebra C7, no entanto, é considerada mais segura para a realização de tal procedimento, já que, na grande maioria das pessoas, segundo os estudos anatômicos disponíveis, esta não possui a artéria vertebral dentro de seu forame transverso, pois este vaso irá penetrar tal estrutura apenas na vértebra C6. Como hoje existem apenas estudos de imagem para avaliação do trajeto desta artéria e suas variações anatômicas, realizamos este estudo anatômico dissecando 40 artérias vertebrais de cadáveres para avaliar a incidência das variações anatômicas. Encontramos 3 casos onde a artéria vertebral penetrou o forame transverso já em C7 (7,5%, o que aumentaria o risco de uma técnica transpedicular neste nível. O restante das peças anatômicas possuíam anatomia habitual.The increasing use of new techniques and materials for surgical treatment of lower cervical spine conditions has come along with an increasing concern regarding potential complications that might occur. The transpedicular fixation technique, frequently used in other spine levels, is used on the cervical spine, while providing more stability than other techniques, it may cause serious complications such as vertebral artery injury, nervous root injury, or facet joint injuries. However, the C7 vertebra is considered safer for performing this procedure, since, in the vast majority of

    Conclusion: We feel that on table decompression and reduction followed by anterior stabilization can be used as the initial surgical approach to manage most types of cervical injuries. In rotation/translational cases where reduction cannot be achieved, monitored cervical traction on the decompressed spine can safely achieve reduction and hence avoid the need for a posterior facetectomy in a large percentage of cases.

    Directory of Open Access Journals (Sweden)

    A. F. Ozer

    2013-01-01

    Full Text Available Surgery of lumbar disc herniation is still a problem since Mixter and Barr. Main trouble is dissatisfaction after the operation. Today there is a debate on surgical or conservative treatment despite spending great effort to provide patients with satisfaction. The main problem is segmental instability, and the minimally invasive approach via microscope or endoscope is not necessarily appropriate solution for all cases. Microsurgery or endoscopy would be appropriate for the treatment of Carragee type I and type III herniations. On the other hand in Carragee type II and type IV herniations that are prone to develop recurrent disc herniation and segmental instability, the minimal invasive techniques might be insufficient to achieve satisfactory results. The posterior transpedicular dynamic stabilization method might be a good solution to prevent or diminish the recurrent disc herniation and development of segmental instability. In this study we present our experience in the surgical treatment of disc herniations.

    Full Text Available Laminoplasty is one surgical option for cervical spondylotic myelopathy. It was developed to avoid the significant risk of complications associated with alternative surgical options such as anterior decompression and fusion and laminectomy with or without posterior fusion. Various laminoplasty techniques have been described. All of these variations are designed to reposition the laminae and expand the spinal canal while retaining the dorsal elements to protect the dura from scar formation and to preserve postoperative cervical stability and alignment. With the right surgical indications, reliable results can be expected with laminoplasty in treating patients with multilevel cervical myelopathy.

    Full Text Available The incidence of cervical fibroids is 0.5-1%. It is usually single; they are usually confined to supravaginal portion of the cervix. Rarely it becomes submucous and polypoidal. So it is usually subserous or interstitial. It can be anterior, posterior or central in position. We had different types of cervical fibroids of which we will describe a few. Usually cervical fibroids cause infertility, difficulty in labor, infections, metrorrhagia, menorrhagia, constipation, retention of urine and dyspareunia. The cervical fibroid distorts the shape of cervix and grows bigger. It pushes the uterus upward giving the appearance of lantern of Saint Paul’s dome in a case of a central cervical fibroid. Most of the patients in the reproductive age get admitted for menorrhagia due to fibroid. Its growth is dependent on estrogen. It does not grow after menopause

    Full Text Available Background: Cervical disc replacement is becoming an increasingly popular treatment option for cervical myelopathy. It retains motion at the affected segment, unlike anterior cervical discectomy and fusion. The aim of this study is to assess the outcomes of a series of patients who underwent Activ C disc replacement for cervical myelopathy. Materials and Methods: A series of patients at the above Trust with clinical and radiological evidence of cervical myelopathy who were suitable for cervical disc replacement from 2007 to 2009 were included. Implants were inserted by one of two consultant surgeons {IMS, MO′M}. Patients were assessed preoperatively and at six, 12 and 24 months, postoperatively, with a visual analogue score (VAS for neck and arm pain severity and frequency, the Neck Disability Index questionnaire (NDI and the Centre for Epidemiologic Studies Depression questionnaire (CES-D. Results: Ten patients underwent surgery between May 2007 and July 2009, 6 women, and 4 men. Average age was 54 years (40-64. Disc levels replaced were: four at C4-5; eight at C5-6; seven at C6-7. Three patients had one disc replaced, five patients had two discs replaced, and two patients had three discs replaced. The VAS for neck pain improved from 5.9 pre-operatively to 1.4-24 months postoperatively and the VAS arm pain improved from 5.4 to 2.6. The NDI improved from 51% preoperatively to 26.8% at 24 months postoperatively. The CES-D showed a slight increase from 19.5 preoperatively to 21.7 at 24 months, postoperatively. Conclusion: Cervical decompression and disc replacement improves pain and function in patients with cervical myelopathy. This benefit is maintained at 24 months post op, with no cases requiring revision.

    2012-01-01

    Full Text Available Cervical spondylotic myelopathy and radiculopathy are common disorders which can lead to significant clinical morbidity. Conservative management, such as physical therapy, cervical immobilisation, or anti-inflammatory medications, is the preferred and often only required intervention. Surgical intervention is reserved for those patients who have intractable pain or progressive neurological symptoms. The goals of surgical treatment are decompression of the spinal cord and nerve roots and deformity prevention by maintaining or supplementing spinal stability and alleviating pain. Numerous surgical techniques exist to alleviate symptoms, which are achieved through anterior, posterior, or circumferential approaches. Under most circumstances, one approach will produce optimal results. It is important that the surgical plan is tailored to address each individual's unique clinical circumstance. The objective of this paper is to analyse the major surgical treatment options for cervical myelopathy and radiculopathy focusing on outcomes and complications.

During one year of severe neck and left arm pain she gradually lost the ability to sing difficult operatic passages which brought an end to her music career. Following a three level anterior cervical decompression and fusion, the neck and arm pain was immediately relieved. One week later her voice and singing ability returned to its full strength and power permitting her to resume her activities as a vocalist. The diagnosis of paresis of the left hemi-diaphragm as part of the cervical disc syndrome was implied by postoperative retrospective inference.

    Objective Cervical hollow threaded fixator (CHTY) was designed and applied to stabilize tha cervical spine following anterior decompression due to cervical spondylosis or acute cervical disc herniation. Methods Medical use titanium alloy with no magnetism was made into a hollow threaded structure with holes on the wall of the fixator. Forly-two patients with cervical spondylosis and acute cervical disc herniation were stabilized using the CHTF technique after anterior decompression. X-ray films and CT scans were taken after the oberation to observe the stability ann fusion rate of the segments. Results Patients were allowed to walk one day after the operation and were followed up for 6 to 36 months. The operated segments were stable and solid fusion was observed 3-6 months after surgery. Conclusions Immediate stability of the operated segments can be obtained using the CHTF technique. Patients ware easy to manage after5 the operation and returned to their jobs in a short time.The CHTF technique is safe and simpa to perfoirme and eliminates the complications of an autograft.It may be an alternative to traditional cervical interbody fusion with bone graft.

    In 1976, Dr. Zhao Dinglin and Dr. Zhang Wenming made the breakthrough. Based on the purpose of releasing bone induced pressure they had completed the first anterior radical cervical decompression and bone grafting + partial rotation. Since then, chinese scholars had continuously explored the pathogenesis, pathological anatomy, pathophysiological features, reasonable classiifcation and many other related issues of cervical spondylosis. In several years from 1970s, the author proposed the concept of cervical nonfusion technology, to accomplish various designs and producing, which was subsequently used in clinical treatment. We brought forward Luschka’s joint diseases and anterior-lateral decompression surgery on the purpose of resecting Luschka’s joints. To reduce the damage to the cervical spine anatomy, we had designed a cervical anterior undermining decompression instrument ( including “L” shape, “T” shape, “Y” shape and single vertebrae ). We cooperated with Shanghai No. Six Surgical Instruments Factory and produced both conventional and special instruments on cervical spine surgery to improve the accuracy and security in operations. After that, we designed cervical hollow threaded ifxator, artiifcial cervical vertebra body and artiifcial vertebra plate. Combined with the research results concluded by three national forums, we elaborated basic concepts and definitions of cervical researches at different periods. On this basis we introduced those crucial issues such as the natural outcome of the cervical spondylosis, pathological anatomy features, pathogenesis and so on. Also, for some related trending topics we expressed personal viewpoints. For instance, selection of operative approach ( anterior or posterior ), origin, choice and effectiveness of nonfusion technique, and operative essentials of less invasion. Furthermore we put forward the main points on more common clinical diseases: Luschka’s joint diseases and anterior central spinal artery

    2014-11-01

    Video-assisted thoracoscopic surgery (VATS) has been widely used, but surgical resections of superior sulcus tumours remain challenging because of their anatomical location. For such cases, less-invasive procedures, such as the anterior transcervical-thoracic and transmanubrial approaches, have been widely performed because of their excellent visualization of the subclavian vessels. Recently, a combined operative technique with an anterior surgical approach and VATS for anterior superior sulcus tumours has been introduced. Herein, we report three cases of anterior superior sulcus tumours successfully resected by surgical approaches combined with a VATS-based lobectomy. In all cases, operability was confirmed by VATS, and upper lobectomies with hilar and mediastinal lymph node dissections were performed. Subsequently, dissections of the anterior inlet of the tumours were performed using the transmanubrial approach in two patients and the anterior trans-cervical-thoracic approach in one patient. Both approaches provided excellent access to the anterior inlet of the tumour and exposure of the subclavian vessels, resulting in radical resection of the tumour with concomitant resection of the surrounding anatomical structures, including the chest wall and vessels. In conclusion, VATS lobectomy combined with the anterior surgical approach might be an excellent procedure for the resection of anterior superior sulcus tumours.

    Although disc injury is common in cervical spinal fractures the mechanism of disc herniation in cervical fracture dislocations is not known. This study evaluated the pathogenesis of disc hernia in cervical fracture dislocations. Twenty-two patients who underwent anterior and posterior spinal fixation were studied. Findings of preoperative magnetic resonance imaging (MRI) were compared with surgical findings. During surgery, cervical disk hernia were found in six patients (27 %), and the MRI finding of these patients were evaluated in detail. We concluded that the characteristic MRI findings of cervical disc hernia are as follows: (1) discontinuity of injured disc, (2) anterior indentation of spinal cord at the site of dislocated vertebral body, and (3) signal irregularity at the site of interspace between dislocated vertebral body and spinal cord.

METHOD: We present the evaluation of the arthrodesis' rate and cervical alignment in 48 patients with cervical degenerative disease (CDD submitted to anterior cervical discectomy with interposition of polymethylmetacrylate (PMMA. Odom and Nürick scales were used to evaluation of functional status before and after surgery. Cervical spine X-rays were used to access arthrodesis and alignment, at least 2 years after the procedure. RESULTS: Excellent and good results (Odom I and II were obtained in 91% of the patients with radiculopathy and in 69% of those with myelopathy. Using the chi square test of independence (1% of significance, there was no association between excellent and good clinical results with the presence of arthrodesis verified in cervical X-rays. The presence of cervical alignment had association with good results, whereas the misalignment was associated with unfavorable outcomes. Two patients died: one cervical hematoma and other from graft migration with cord compression. CONCLUSIONS: Cervical alignment was more important than fusion to achieve good surgical results in CDD.TEMA E OBJETIVO: O tratamento cirúrgico da radiculopatia cervical com ou sem mielopatia é um tema controverso, embora a discectomia por via anterior seja uma das formas mais comuns de tratamento.

    Degeneration of the cervical spine is part of the normal aging process, usually occurring without clinical symptoms. Symptomatic degeneration most often occurs in the lower cervical spine, presenting as axial neck pain, radiculopathy, myelopathy, or any combination of the three. When conservative treatment does not adequately manage these symptoms, surgical intervention may be required. The longstanding surgical treatment for cervical degeneration is arthrodesis achieved through anterior cerv...

    Percutaneous endoscopic cervical discectomy has evolved as an efficient, minimally invasive spine surgery for cervical disc herniation or radiculopathy. The development of the working channel endoscope makes definitive decompression surgery through a percutaneous approach feasible. There are two methods of approach to target the pathology: anterior and posterior approach. The approach can be determined according to the zone of pathology or the surgeon's preference. The most significant benefits of this endoscopic surgical technique are minimal access tissue trauma and early recovery from the intervention. However, this technique is still evolving and have a steep learning curve. Extensive development of surgical technique and working channel endoscopes will enable us to treat cervical disc herniation more practically. The objective of this review is to describe the cutting-edge techniques of endoscopic surgery in the cervical spine and to discuss the pros and cons of these minimally invasive surgical techniques.

    To enhance the fusion of graft bone in thoracolumbar vertebrae and minimize the postoperative loss of correction, short-segment pedicle screw fixation was reinforced with posterior moselizee bone grafting in vertebrae for spinal fusion in patients with thoracrolumbar vertebrate fractures. Seventy patients with thoracrolumbar vertebrate fractures were treated by short-segment pedicle screw fixation and were randomly divided into two groups. Fractures in group A (n=20) were reinforced with posterior morselized bone grafting in vertebrae for spinal fusion, while patients group B (n=50) did not receive the morselized bone grafting for bone fusion. The two groups were compared in terms of kyphotic deformity, anterior vertebral height, instrument failure and neurological functions after the treatment. Frankel grading system was used for the evaluation of neurological evaluation and Denis scoring scale was employed for pain assessment. The results showed that the kyphosis correction was achieved in both group A and group B (group A: 6.4 degree; group B: 5.4 degree)/At the end of follow-up, kyphosis correction was maintained in group A but lost in group B (P=0.0001). Postoperatively, greater anterior height was achieved in group A than in group B (P<0.01). During follow-up study, anterior vertebral height was maintained only in Group A (P<0.001). Both group A and group B showed good Denis pain scores (P1 and P2) but group A outdid group B in terms of control of severe and constant pain (P4 and P5). By Frankel criteria, the changes in neurological functions in group A was better than those of group B (P<0.001). It is concluded that reinforcement of short-segment pedicle fixation with morselized bone grafting for the treatment of patients with thoracolumbar vertebrae fracture could achieve and maintain kyphosis correction, and it may also increase and maintain anterior vertebral height. Morselized bone grafting in vertebrae offers immediate spinal stability in patients with

    2014-10-01

    Cervical spondylotic myelopathy (CSM) is a common condition. Uninstrumented laminectomy may be complicated by postoperative instability, whereas anterior or posterior decompression with fusion may be associated with stiffness and adjacent segment disease. Cervical laminoplasty, initially oriented towards pediatric patients and ossification of the posterior longitudinal ligament, becomes an interesting surgical alternative to decompress and reconstruct cervical anatomy without fusion. Eighteen patients (12 men, 6 women), mean age 64.2 who presented with CSM were treated surgically using multilevel laminoplasty, and reviewed after 1 month, 6 months, 1 year and 2 years. Clinical evaluation was performed based on the Benzel-JOA and Nurick scores. The preoperative mean Benzel-JOA score was 13.55; Preoperative mean Nurick score was 1.88. Preoperative MRI was carried-out in 16/18 patients. Intramedullary hyperintensity in T2 was observed in 6 patients. The operation was performed on 2 levels (4 patients) 3 levels (11 patients) and 4 levels (3 patients). We used the open-door hinged laminoplasty technique, using metallic implants, without bone graft. At one month FU, mean JOA score was 15.44, and Nurick dropped to 1.05. At 6 months, mean JOA was 16.28 and Nurick was 0.71. At one year, the mean JOA score was 16.16, and Nurick was 0.83. At 2 years, mean JOA was 17.5, and Nurick was 0.25. One infection, one dural tear and one transient episode of C5 paresthesia were observed. We conclude that spinal cord decompression by open-door laminoplasty for CSM allows significant clinical improvement observed progressively in the two years following surgery. PMID:25239380

    Full Text Available Animals are commonly used to model the human spine for in vitro and in vivo experiments. Many studies have investigated similarities and differences between animals and humans in the lumbar and thoracic vertebrae. However, a quantitative anatomic comparison of calf, pig, and human cervical spines has not been reported.To compare fundamental structural similarities and differences in vertebral bodies from the cervical spines of commonly used experimental animal models and humans.Anatomical morphometric analysis was performed on cervical vertebra specimens harvested from humans and two common large animals (i.e., calves and pigs.Multiple morphometric parameters were directly measured from cervical spine specimens of twelve pigs, twelve calves and twelve human adult cadavers. The following anatomical parameters were measured: vertebral body width (VBW, vertebral body depth (VBD, vertebral body height (VBH, spinal canal width (SCW, spinal canal depth (SCD, pedicle width (PW, pedicle depth (PD, pedicle inclination (PI, dens width (DW, dens depth (DD, total vertebral width (TVW, and total vertebral depth (TVD.The atlantoaxial (C1-2 joint in pigs is similar to that in humans and could serve as a human substitute. The pig cervical spine is highly similar to the human cervical spine, except for two large transverse processes in the anterior regions ofC4-C6. The width and depth of the calf odontoid process were larger than those in humans. VBW and VBD of calf cervical vertebrae were larger than those in humans, but the spinal canal was smaller. Calf C7 was relatively similar to human C7, thus, it may be a good substitute.Pig cervical vertebrae were more suitable human substitutions than calf cervical vertebrae, especially with respect to C1, C2, and C7. The biomechanical properties of nerve vascular anatomy and various segment functions in pig and calf cervical vertebrae must be considered when selecting an animal model for research on the spine.

    Full Text Available The objective of this study was to measure intradiscal pressure (IDP changes in the lower cervical spine during a manual cervical distraction (MCD procedure. Incisions were made anteriorly, and pressure transducers were inserted into each nucleus at lower cervical discs. Four skilled doctors of chiropractic (DCs performed MCD procedure on nine specimens in prone position with contacts at C5 or at C6 vertebrae with the headpiece in different positions. IDP changes, traction forces, and manually applied posterior-to-anterior forces were analyzed using descriptive statistics. IDP decreases were observed during MCD procedure at all lower cervical levels C4-C5, C5-C6, and C6-C7. The mean IDP decreases were as high as 168.7 KPa. Mean traction forces were as high as 119.2 N. Posterior-to-anterior forces applied during manual traction were as high as 82.6 N. Intraclinician reliability for IDP decrease was high for all four DCs. While two DCs had high intraclinician reliability for applied traction force, the other two DCs demonstrated only moderate reliability. IDP decreases were greatest during moving flexion and traction. They were progressevely less pronouced with neutral traction, fixed flexion and traction, and generalized traction.

    Criteria for return to sports and athletic activities after cervical spine surgery are unclear. There is limited literature regarding the outcomes and optimal criteria. Determining return to play criteria remains a challenge and continues to depend on the experience and good judgment of the treating surgeon. There is strong consensus in the literature, despite lack of evidence-based data, that athletes after single-level anterior cervical discectomy and fusion (ACDF) may safely return to collision and high-velocity sports. The athlete should be counseled and managed on a case-by-case basis, taking into consideration the type of sport, player-specific variables, and type of surgery performed. PMID:27543397

    Langerhans cell histiocytosis (LCH), a disorder of the phagocytic system, is a rare condition. Moreover, spinal involvement causing myelopathy is even rare and unusual. Here, we report a case of atypical LCH causing myelopathy, which was subsequently treated by corporectomy and fusion. An 8-year-old boy presented with 3 weeks of severe neck pain and limited neck movement accompanying upper and lower limbs motor weakness. CT scans revealed destruction of C5 body and magnetic resonance imaging showed a tumoral process at C5 with cord compression. Interbody fusion using anterior cervical plate packed by autologus iliac bone was performed. Pathological examination confirmed the diagnosis of LCH. After the surgery, the boy recovered from radiating pain and motor weakness of limbs. Despite the rarity of the LCH in the cervical spine, it is necessary to maintain our awareness of this condition. When neurologic deficits are present, operative treatment should be considered. PMID:22552159

    Full Text Available Cervical arthroplasty after anterior decompression with insertion of a prosthetic total disc replacement has been suggested as an alternate to anterior cervical fusion. Currently there are four cervical arthroplasty devices available on the market whose results in clinical use have been reported. Each device varies in terms of materials, range of motion, insertion technique and constraint. It is not known which device is ideal. Early studies suggest that in the short term, the complication rate and efficacy is no worse than fusion surgery. Long-term results have not yet been reported. This review examines the current prostheses available on the market as well as discussing issues regarding indications and technique. Pitfalls are discussed and early experiences reviewed. In time, it is hoped that a refinement of cervical arthroplasty occurs in terms of both materials and design as well as in terms of indications and clinical outcomes as spinal surgeons enter a new era of the management of cervical spine disease.

    A 35 year old woman with endometrial cancer and cervical extension underwent F18 FDG PET CT and MRI studies after resection of a cervical mass presumed to be cervical myoma. The patient underwent cervical myomectomy and the histopathologic report revealed poorly differentiated invasive carcinoma. Cervical cancer was ruled out because the patient had no history of sexual intercourse and was negative for human papilloma virus infection. The patient underwent radical hysterectomy, bilateral salpingo oophorectomy, pelvic and para aortic lymph node dissection, and multiple biopsies. F18 FDG PET CT showed intense FDG uptake along the cervix wall. T2 weighted MRI also revealed a mass lesion with high SI involving the anterior and posterior lips of the uterine cervix. Another area of focal increased uptake above the endometrial lesion in the left pelvic cavity was observed on PET CT and MRI, possibly due to a functioning ovary. PET CT and MRI were interpreted as showing a dual concordant malignant lesion due to separated FDG uptakes and high SI without any connection between the cervical and endometrial lesions. F18 FDG PET CT showed intense FDG uptake along the endometrium. Given the patient's history and the fact that she was not menstruating at the time of imaging, this intense uptake was interpreted as another pathologic lesion, suggesting dual primary lesions. A suspected heterogeneous mass lesion along the endometrium suggesting concordant endometrial cancer was found on MRI. Endometrial cancer with cervical extension is sometimes difficult to differentiate from primary cervical cancer. The final histopathologic report showed poorly differentiated endometrial adenocarcinoma with cervical extension, although the FDG PET CT and MRI findings were suggestive of concordant cervical and endometrial cancer. Although histopathologic confirmation is necessary for final diagnosis, MRI and FDG PET CT studies may aid in the differential diagnosis. A metastatic cervical mass

    2013-11-01

    Full Text Available Objective To investigate the clinical characteristics, classification, surgical approach, complication and prognosis of cervical dumbbell-shaped tumors. Methods Twenty-six consecutive cases with cervical dumbbell-shaped tumors were retrospectively studied. According to tumor location by imaging examination, all tumors were divided into 3 types. Type Ⅰ (17 cases was mostly intravertebral and foraminal. Surgery through posterior approach was performed and internal fixation was operated in 8 cases. Type Ⅱ (4 cases was mostly paravertebral and foraminal. Surgery through the anterolateral approach was performed without internal fixation. Type Ⅲ (5 cases was equalization of intravertebral and paravertebral, and underwent surgery through combined posterior-anterolateral approach and internal fixation was performed in all of those cases. If the unilateral facet joint was destroyed, internal fixation was necessary. Lateral mass screw internal fixation and transpedicular screw fixation supplemented by fusion with autologous iliac bone graft were used to maintain cervical spinal stability. Results Among 26 patients there were 19 schwannomas, 4 neurofibromas, 2 gangliocytoma and 1 spinal meningioma. Total and subtotal tumor resection was achieved in 23 and 3 patients respectively. Among them 50% (13/26 of the cases were used internal fixation including 8 TypeⅠand 5 Type Ⅲ patients. The follow-up period was from 7 to 62 months, and mean time was 30 months. Four cases (15.38% were found local tumor recurrence. Two cases suffered with surgical infection and cerebrospinal fluid leakage. There was no spinal cord injury and spinal deformity. Conclusion In order to increase the total resection rate and decrease recurrence rate, surgical approach should be selected according to the imaging classification of tumors. Stability reconstruction is absolutely necessary for the patients with facet joint destroyed.

    Cervical cancer is one of the leading causes of cancer and cancer-related deaths among women worldwide. More than 85% of cases and deaths occur in the developing world where the availability of effective screening is limited. In this issue of the journal, Pierce and colleagues (beginning on page 1273) describe a novel technique using a high-resolution microendoscope (HRME) to diagnose cervical dysplasia. This perspective reviews the limitations of existing cervical cancer screening methods currently in use in low-resource settings and the potential for HRME imaging to contribute to cervical cancer prevention in the developing world.

    Objective To explore the feasibility of one stage solution and posterior fusion surgery through the high anterior cervical retropharyngeal approach for irreducible atlantoaxial dislocation and its curative effect. Method The solution and posterior fusion surgery was performed in 12 patients (age range, 26~58 years; mean age, 46 years) with irreducible atlantoaxial dislocation, of whom, 8 were males and 4 females. All the patients received skull traction and the translocation and rotation of the atlas were assessed by X-ray, MRI and CT three-dimensional reconstruction before the surgery in all the patients. The articular capsules of articulatio atlantoepistrophicas were exposed and the scar tissue and steophyma were resected by the surgery. With continuous skull traction, the atlas was reduced and fixed with pedicle screws and the atlantoaxial fusion was performed by iliac bone graft during one stage surgery. Japanese orthopaedic Association (JOA) score system was used to evaluate the clinical outcomes before the surgery and 12 months after the surgery. Results All the patients were followed up from 12 to 28 months (mean, 18 months). Hypoglossal palsy occurred in one patient, who recovered from hypoglosed palsy 2 months after the surgery. The nerves, vertebral arteries and esophagus injuries, and leakage of cerebrospinal fluid were not observed in all the patients. JOA score [(15.6±l.l)points] was significantly higher 12 months after the surgery than that [(9.3±l.l)points] before the surgery (P<0.05). The grafted bones was well fused into the receptor bones and there was good internal fixation in all the patients. Conclusion The one stage solution and posterior fusion surgery through the high anterior cervical retropharyngeal approach is an effective method to treat the irreducible atlantoaxial dislocation.%目的 探讨一期颈椎前方高位咽后入路松解后路寰枢椎融合治疗难复性寰枢椎脱位的可行性及效果.方法 本组共收治

    Full Text Available These days, as a consequence of the improvement in technology and increase in the use of motor vehicles, spine injuries have become common. Spine traumas, which often occur after motor vehicle accidents, are observed mostly in cervical regions, particularly in the subaxial cervical region, which is also known as the subcervical region, and neurological damage occurs in 70% of the patients. Despite still being controversial, the common ranging for neurological evaluation is the American Spinal Injury Association ranging, which includes the motor and sensory loss and accordingly, the impairment rate. In subaxial cervical traumas, acute neurological deterioration is an indication and therefore requires urgent surgical treatment. The choice of anterior or posterior approach substantially depends on the traumatization mechanism, affected tissues, and neurological deterioration occurring after. The state of patient and instability are the most two important factors affecting the treatment decision. Although the anterior approach is accepted as a routinely available and easily applicable surgical technique, it lacks in the burst fractures involving the three colons, which shows a stabilization disorder. The anterior plate screw technique and posterior lateral mass screw application applied in our clinic are reviewed in literature and are discussed in two cases. Although the best clinical results are achieved in cases where only anterior surgery is performed and in cases where instability is excessive, in unstable compression and blow-out fractures, even if neurological deficit and three colon involvement are not observed in the patient, the requirement of posterior fusion is observed.

    Full Text Available We report a rare patient of a simultaneous extradural and intradural compression of the cervical spinal cord due to co-existent intervertebral disc herniation and an intradural schwannoma at the same level. The intradural lesion was missed resulting in recurrence of myelopathy after a surprisingly complete functional recovery following anterior cervical discectomy. Retrospectively, it was noted that the initial cord swelling noticed was tumor being masked by the compression produced by the herniated disc. A contrast magnetic resonance imaging scan is important in differentiating intradural tumors of the spinal cord. A high index of suspicion is often successful in unmasking both the pathologies.

    Visualization of the lower cervical spine with a lateral radiograph poses a challenge secondary to encroachment of the shoulders. Applying traction to the arms or taping the shoulders down provides adequate visualization in most patients, but imaging the mid- to lower cervical levels presents a significant challenge in patients with stout necks. We present a variation of the lateral radiograph that is 30º oblique from horizontal and 30º cephalad from neutral and used in a series of patients with stout necks that require anterior instrumentation of the lower cervical spine. We reviewed intraoperative images of 2 patients who underwent anterior cervical spine surgery at our institution, and assessed type of procedure, body mass index, and outcome scores. Our variation provided improved visualization relative to a lateral view and was used intraoperatively to confirm correct-level hardware placement in both patients. PMID:26866322

    2004-07-01

    Objective: The objective of this study was to evaluate the diagnostic value of prevertebral soft tissue swelling in cervical spine injuries. Materials and methods: A group of 107 consecutive patients with suspected injuries of the cervical vertebrae were reviewed retrospectively to identify the presence of prevertebral soft tissue swelling and to investigate the association of prevertebral soft tissue swelling with the types and degrees of cervical spine injuries. Results: Prevertebral soft tissue swelling occurred in 47 (43.9%) patients. Of the 47 patients, 38 were found with bony injury and nine were without. The statistic difference was significant (P<0.05). No correlation was demonstrated between soft tissue swelling and either the injured level of the cervical vertebrae or the degree of the spinal cord injury (P>0.05). Anterior element injuries in the cervical vertebrae had widening of the prevertebral soft tissue more than posterior element injuries (P<0.05). Conclusion: The diagnostic value of prevertebral soft tissue swelling for cervical spine injuries is significant, but the absence of this sign does not mean that further image evaluation can be spared.

    Post-traumatic cervical spondyloptosis is a rare condition associated with high energy injuries, and to our knowledge only case reports are available. There are no universally accepted treatment paradigms for these cases and management is individualised according to the case and surgeon preference. We retrospectively analysed our management and clinical outcomes of this condition. From January 2007 to August 2014 we treated eight patients with cervical spondyloptosis at our institute. Only two patients had no neurological deficits; all the remaining patients had partial cord injury. Seven were treated surgically with preoperative traction followed by anterior cervical discectomy and fusion with fixation in three patients, and combined anterior and posterior fusion and fixation in four. Depending on the presence of anterior compression by a disc an anterior first or posterior first approach was advocated. All four combined anterior and posterior fusion and fixation patients needed to be turned more than once (540°). There was no neurological deterioration in any of the patients, as they either improved or remained stable neurologically. Post-traumatic cervical spondyloptosis is a challenging entity to manage. Surgery can be done safely with good clinical and radiological outcome and needs to be tailored to the individual patient. PMID:26922508

    The plicae palmatae are normal endocervical folds on the anterior and posterior walls. The median longitudinal ridges of the plicae palmatae have been considered to represent a remnant of fused Müllerian ducts. We present a case of uterus didelphys in which the longitudinal ridge of the plicae palmatae were obviously demonstrated on both of the uterine cervices on axial T2-weighted image. The observation of the plicae palmatae on the duplicated uterine cervices indicates the plicae palmatae is an inherent structure of the cervical canal, not a remnant of fused Müllerian duct.

    Full Text Available The Thoracic Outlet is bounded by the first thoracic Vertebra posteriorly, superior border of manubrium sternum anteriorly, and the first rib and costal cartilage laterally. Thoracic outlet syndrome is a general term for a number of disorders producing neurovascular compression over this area. Cervical Rib is a congenital bony abnormality in which an extra rib is present superior to first rib is attached to C7 vertebra. Of the many factors which can cause neurovascular compression, 30% of the cases is due to bony abnormalities. Cervical rib is one of the important bony factors which lead to thoracic outlet syndrome due to the displacement and compression of the neurovascular structures while crossing the thoracic outlet to the upper limb. In the collection of bones in the Institute of Anatomy Madras medical college, cervical ribs were present bilaterally in two specimens. The present paper will definite be useful to clinicians while dealing with thoracic outlet syndrome.

    Background A simple, safe and effective therapeutic strategy for traumatic instability of the subaxial cervical spine, as well as its prognostic assessment, is still controversial.Methods The therapeutic options for 83 patients of traumatic instability of the subaxial cervical spine, whose average age was 35 years, were determined, according to the Allen-Ferguson classification, general health and concomitant traumatic conditions, neurological function, position of compression materials, concomitant traumatic disc herniation/damage, concomitant locked-facet dislocation, the involved numbers and position, and the patients' economic conditions. An anterior, posterior or combination approach was used to decompress and reconstruct the cervical spine. No operations with an anterior-posterior-anterior approach were performed.Results The average follow-up was three years and nine months. Distraction-flexion and compression-flexion were the most frequent injury subtypes. There were 46, 28 and 9 cases of anterior, posterior and combination operations, respectively. The average score of the Japanese Orthopaedics Association, visual analog scale and American Spinal Cord Injury Association (ASIA) motor index improved from 11.2, 7.8 and 53.5, respectively, before operation, to 15.3, 2.6 and 67.8, respectively, at final follow-up. For incomplete spinal cord injury (SCI), the average ASIA neurological function scale was improved by 1-2 levels. Patients with complete SCI had no neurological recovery, but recovery of nerve root function occurred to different extents. After surgery, radiological parameters improved to different extents. Fusion was achieved in all patients and 12 developed complications.Conclusions The best surgical strategy should be determined by the type of subaxial cervical injury, patients' general health, local pathological anatomy and neurological function.

    Full Text Available Background: Cervical spondylotic amyotrophy (CSA is a rare clinical syndrome resulting from cervical spondylosis. Surgical treatment includes anterior cervical decompression and fusion (ACDF, and laminoplasty with or without foraminotomy. Some studies indicate that ACDF is an effective method for treating CSA because anterior decompression with or without medial foraminotomy can completely eliminate anterior and/or anterolateral lesions. We retrospectively evaluated outcome of surgical outcome by anterior cervical decompression and fusion (ACDF. Materials and Methods: 28 CSA patients, among whom 12 had proximal type CSA and 16 had distal type CSA, treated by ACDF, were evaluated clinicoradiologically. The improvement in atrophic muscle power was assessed by manual muscle testing (MMT and the recovery rate of the patients was determined on the basis of the Japanese Orthopedic Association (JOA scores. Patient satisfaction was also examined. Results: The percentage of patients, who gained 1 or more grades of muscle power improvement, as determined by MMT, was 91.7% for those with proximal type CSA and 37.5% for those with distal type CSA (P < 0.01. The JOA score-based recovery rates of patients with proximal type and distal type CSA were 60.8% and 41.8%, respectively (P < 0.05. Patient satisfaction was 8.2 for those with proximal type CSA and 6.9 for those with distal type CSA (P < 0.01. A correlation was observed among the levels of improvement in muscle power, JOA score based recovery rate, patient satisfaction and course of disease (P < 0.05. Conclusion: ACDF can effectively improve the clinical function of patients with CSA and result in good patient satisfaction despite the surgical outcomes for distal type CSA being inferior to those for proximal type CSA. Course of disease is the fundamental factor that affects the surgical outcomes for CSA. We recommend that patients with CSA undergo surgical intervention as early as possible.

    Congenital anterior urethral diverticulum (CAUD) may be found all along the anterior urethra and may present itself at any age, from infant to adult. Most children with this condition present with difficulty in initiating micturition, dribbling of urine, poor urinary stream, or urinary tract infection. A careful history will reveal that these children never had a good urinary stream since birth, and the telltale sign is a cystic swelling of the penile urethra. In this paper, we present two cases of CAUD that were managed by excision of the diverticulum with primary repair. PMID:26328174

  5. Operative treatment via anterior approaches for cervicothoracic vertebrae tumors: surgical techniques and primary outcome

    2006-01-01

    Objective: To sum up 7 patients with cervicothoracic vertebrae tumors (C7 to T3) from March 1999 and May 2002, who underwent operative treatment via anterior approaches. Methods :The anterior approaches included low anterior cervical approach and high transthoracic approach. In 5 cases of segments of T1 and above involved, the low anterior cervical approaches were adopted, otherwise the high transthoracic approaches were used(2 cases). Excision of tumor was carried out according to demands of the Weinstein-Boriani-Biagini (WBB) staging system. Spine stability was reconstructed by bone autografting and instrumentation. There were 4 cases of primary tumor and 3 of metastases. Their mean age was 45.1 years (23 to 66). The mean follow up was 18.9 months (3 to 45). Results were evaluated by occurrence of complications, improvement of symptoms, local recurrence and mortality. Results: All patients stood surgery well. No significant complications occurred during and after operation. Local pain was significantly alleviated and neurological deficit was improved at least one Frankel grade. Three patients died.Local tumor control was obtained in 6 patients (85.7 %) until the end of follow-up. Conclusion:Our experience showed that via low anterior cervical approach and high transthoracic approach, the cervicothoracic vertebrae tumor could be excised safely and adequately. Moreover, excision of tumor according to the WBB surgical staging system and reconstruction of spine stability have made great contribution to local tumor control and the neurological function improvement.

    The objective was to study characteristic MRI findings in cervical spine fractures complicating ankylosing spondylitis (AS). Technical issues related to MRI are also addressed. A review of 6,774 consecutive cervical spine multidetector CT (MDCT) scans obtained during 6.2 years revealed 33 ankylosed spines studied for suspected acute cervical spine injury complicating AS. Of these, 20 patients also underwent MRI. On MRI, of these 20 patients, 19 had a total of 29 cervical and upper thoracic spine fractures. Of 20 transverse fractures traversing both anterior and posterior columns, 7 were transdiskal and exhibited less bone marrow edema than did those traversing vertebral bodies. One Jefferson's, 1 atlas posterior arch (Jefferson's on MDCT), 2 odontoid process, and 5 non-contiguous spinous process fractures were detectable. MRI showed 2 fractures that were undetected by MDCT, and conversely, MDCT detected 6 fractures not seen on MRI; 16 patients had spinal cord findings ranging from impingement and contusion to complete transection. Magnetic resonance imaging can visualize unstable fractures of the cervical and upper thoracic spine. Paravertebral hemorrhages and any ligamentous injuries should alert radiologists to seek transverse fractures. Multiple fractures are common and often complicated by spinal cord injuries. Diagnostic images can be obtained with a flexible multipurpose coil if the use of standard spine array coil is impossible due to a rigid collar or excessive kyphosis. (orig.)

The aim of this paper is to report an arthroplasty failure in a patient with KFS. A 36-year-old woman with KFS underwent two-level arthroplasty for adjacent segment disc degeneration. Anterior migration of the cranial prosthesis was encountered 5 months postoperatively and was successfully revised with anterior cervical fusion. Cervical arthroplasty in an extensively stiff and fused neck is challenging and may lead to catastrophic failure. Although motion preservation is desirable in KFS, the special biomechanical features may hinder arthroplasty. Fusion or hybrid constructs may represent more reasonable options, especially when multiple fused segments are present.

    Of the many types of human papillomavirus (HPV), more than 30 infect the genital tract. The association between certain oncogenic (high-risk) strains of HPV and cervical cancer is well established. Although HPV is essential to the transformation of cervical epithelial cells, it is not sufficient, and a variety of cofactors and molecular events influence whether cervical cancer will develop. Early detection and treatment of precancerous lesions can prevent progression to cervical cancer. Ident...

    Full Text Available Introduction: Inflammatory cervical swelling may have several causes. The jugular vein thrombosis is a rare entity, often forgotten. Most frequently arises due to a cervical sepsis by the use of a central venous catheter or intravenous drug abuse (drug addicts. Rarely, is secondary to a hypercoagulability state associated with a visceral carcinoma (Trousseau Syndrome. Material and Methods: The authors present the case of a 65 years old male, who used the ENT Emergency Service due to a painful left cervical swelling with local and systemic inflammatory signs of 3 days duration. Results: An cervical ultrasound suggested a neck abscess. CT was performed and confirmed the ultrasound results. Because of its location in the path of the internal jugular vein, we requested re-evaluation by CT with intravenous contrast and doppler ultrasound, obtaining the diagnosis of thrombosis of the internal jugular vein. Further studies were conduct to clarify the hypercoagulability state, since the patient had no known predisposing factor. Finally the diagnosis of unresectable gastric carcinoma was made. Discussion and Conclusion: The ENT must be aware and be able to understand any cervical imagiologic studies. A deep knowledge of the anatomical imagiología is important for the diagnosis of jugular thrombosis. When we have a case of spontaneous jugular thrombosis, we must look for possible visceral carcinoma.

    This study reports on a case that forces re-examination of merits and demerits of anterior cervical fusion. A 79-year-old male was brought to the emergency room (ER) of our hospital after he fell and struck the occipital region of his head following excessive alcohol consumption. Four years prior, he had undergone anterior cervical discectomy and fusion of C5/6 and a magnetic resonance imaging (MRI) performed 3 years after this surgery indicated that he was suffering from degeneration of C6/7 intervertebral discs. After arriving at the ER, he presented motor impairment at level C7 and lower of manual muscle testing grade 1 as well as moderate loss of physical sensation from the trunk and peripheries of both upper limbs to the peripheries of both lower limbs (Frankel B). Cervical computed tomography (CT) indicated anterior dislocation of C6/7, and MRI indicated severe spinal cord edema. We performed manipulative reduction of C6/7 with the patient under general anesthesia. Next, we performed laminectomy on C5-T1 and posterior fusion on C6/7. Postoperative CT indicated that cervical alignment had improved, and MRI indicated that the spinal cord edema observed prior to surgery had been mitigated. Three months after surgery, motor function and sensory impairment of the lower limbs had improved, and the patient was ambulatory upon discharge from the hospital (Frankel D). In the present case, although C5 and 6 were rigidly fused, degeneration of the C6/7 intervertebral disc occurred and stability was compromised. As a result, even slight trauma placed a severe dynamic burden on the facet joint of C6/7, which led to dislocation. PMID:26933361
