Abstract

INTRODUCTION: The Present dissertation is going to be a prospective study of 80 cases of lumbar canal stenosis to be treated for a period of one year (2011-2012) by conservative treatment and operative modalities such as decompressive laminectomy, discectomy, foraminotomy / medial facectomy, excision of hypertrophied ligamentum flavum. AIMS AND OBJECTIVES: 1. To measure spinal canal at the level of disc, lateral recess, interpedicular distance using digital/ plain x ray LS spine, CT LS spine, MRI LS spine &correlation with clinical findings and outcome of various modalities of treatment. 2. To measure body/canal ratio (jones Thompson index) and correlation with clinical findings &outcome of surgery. 3. To illustrate the variations in spinal canal &lateral recess measurements using CT scan, MRI scan & study the statistical significance of the variations. 4. To evaluate the results of surgical treatment in LCS and its correlation with lumbar canal measurement by radiological investigations & clinical findings. 5. To compare the results of conservative and surgical treatment. MATERIALS AND METHODS: This is a randomized study of 80 patients of lumbar canal stenosis of age between 20-60 years which was carried out in department of neurosurgery during the year 2011-2012 at Govt. Stanley Medical College & Hospital, Chennai. Data will be collected from the patients by their history telling, clinical examination & appropriate investigation. Documentation of patients information consisting of the patients particulars, history, clinical findings, investigations, operative procedures and its findings, follow up were recorded on a proforma. CONCLUSIONS: Variations seen in the spinal canal and lateral recess diameter measured by Xray, CT, MRI lumbosacral spine in this study is satistically more significant than any other studies. Significant neurological deficit occurs even with mean spinal canal diameter of 15.1mm in this study when compared to diameter of 12 mm of other studies. Overall good surgical outcome compared to other studies and better surgical results when compared to conservative treatment in this study is due to foraminotomy/medial facectomy done in all cases. Jones Thompson index applied in this study correlates well with clinical neurological deficit as well as with surgical outcome.
