“…Moreover, sagittal MR images better de®ne the extent of cephalocaudal involvement, which is an important surgical consideration. MRI is the imaging modality which best dierentiates calci®cation and ossi®cation of posterior elements, 14 and it can identify ventral pathologic lesions more accurately than CT. MRI has been more frequently used and is more useful in the authors' experience. In our series, the most frequent pathologic lesion was OLF.…”

Objectives: To describe the underlying causes, surgical results and prognostic factors in thoracic stenosis causing myelopathy. Methods: The underlying causes and surgical results were analyzed retrospectively in 28 cases of thoracic spinal stenosis which caused myelopathy. Degenerative spondylosis was the most common cause, and three cases were associated with systemic diseases. Decompressive laminectomy was performed in 24 cases, anterior decompression in ®ve cases, and combined decompression in one case. Ossi®cation of ligamentum¯avum was found in 18 cases, facet hypertrophy in 13, ossi®cation of posterior longitudinal ligament in six, and ventral spur in four. Postoperatively 16 patients improved and four patients worsened. Follow-up ranged from 2 months to 5 years and 8 months). Statistical analysis was performed using a w 2 test to investigate the relationship between subjects. Multivariant analysis (general linear model) was used to determine the factors which in¯uence surgical outcome. Results: There were neurological improvements in 16 patients, in whom Nurick grade changed from 3.3 preoperatively to 1.8 postoperatively. Eight patients showed no signi®cant change in functional grade and four patients deteriorated after decompressive laminectomy. The group of which initial symptom duration was less than 2 years showed better results (P=0.006). The group with sucient decompression and no additional proximal stenosis had better treatment outcome (P=0.005, P=0.002). Conclusion: Chronic severe myelopathy caused by thoracic spinal stenosis can be reversible with appropriate decompression. Surgical outcome was dependent on initial symptom duration, sucient decompression and presence of additional proximal stenosis.

Background: Ossification of the posterior longitudinal ligament (OPLL) is a complex multi-factorial disease process having both metabolic and biomechanical factors. The objective of this study was to assess the surgical out come and post operative functional improvement in patients with cervical OPLL at a tertiary care centre.Methods: This prospective observational study included 35 patients undergoing surgery for cervical OPLL in the department of neurosurgery, Care hospitals Hyderabad from October 2015 to October 2016 with follow up at 3months and 6 months.Results: Total 35 patients who underwent surgery, majority (77.15%) were males and (22.85%) were female. The age of the patients was between 30 to 70 years. The most common type of OPLL was found to be segmental and mixed type. Nurick grade improved by 1.12 in anterior approach vs 0.66 in posterior approach. Recovery rates observed in anterior approach is 57.72% while in posterior surgical approach it is 48.87%. No complication was observed in this study.Conclusions: OPLL is more common in males as compared to females. The average age of presentation is sixth decade. Younger patients have better outcomes. The most common variant of OPLL is segmental. The recovery rate achieved from anterior approach are better than those from the posterior approach. Improvement in NURICKS score is more in anterior surgical group than in posterior surgical group. No complications seen in this study. No mortality seen in this study.

ARTICLE INFO ABSTRACT The purpose of the study is to establish the role of magnetic resonance imaging (MRI) in the evaluation of various causes of compressive myelopathy, characterization of compressive lesions and to classify the lesions based on location into extradural / intradural compartments. Seventy patients who were clinically suspected to have compressive myelopathy were subjected for MRI. In this study, extradural compression due to degenerative changes (54.3%) was found to be the most common cause of compressive myelopathy, followed by infectious spondylitis (14.3%), post traumatic compressive myelopathy (12.8%), primary neoplasms & metastases (12.8%) and other causes (5.8%). There were 6 cases of intradural extramedullary pathology, remainder (64 cases) of the cases showed extradural location of pathology. MRI detected cord changes in 97% of cases with cord compression and also assessed the integrity of spinal cord, intervertebral discs and ligament after acute spinal trauma. MRI is very definitive, sensitive, accurate, though costly but very specific, non-invasive, radiation free modality for evaluation of compressive myelopathy.
