Ossification of Cervical Posterior Longitudinal Ligament: ClinicoRadiological Correlation and Surgical Outcome.
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 16, Issue 4
Abstract
Background: The precise contribution of static and dynamic factors to the disease progression of the cervical OPLL ( Ossification of posterior longitudinal ligament ) remains controversial. So an attempt has been made to correlate the clinical features with preoperative radiological findings and postoperative outcome. Methods: After Institutional ethical clearance, written informed consent were taken from 26 patients (31 to 70 years of age) to enroll in this prospective longitudinal study over 3 years period. OPLL was proven radiologically and the degree of preoperative myelopathy was assessed by modified Japanese Orthopaedic Association( mJOA) score. Decompressive laminectomy was performed in all the patients and Hirabayashi’s recovery rate was assessed at 3 and 6 months postoperatively. Results: It was found that poor surgical outcome was correlated with age > 60 years, duration of myelopathy>2 years, preoperative bladder dysfunction (p< 0.001), MRI cord signal changes ( p=0.041) and lower cross sectional area of the cervical spinal cord (p = 0.035). Conclusion: Preoperative poor functional status of the patient as well as radiological findings of lower cross sectional area of cervical spinal cord and signal changes in MRI are predictive of poor outcome.
