Clinical Factors that Predict the Surgical Outcome of Ossification of Ligamentum Flavum of Spine – Series of 31 Cases
Journal Title: International Journal of Contemporary Medical Research - Year 2018, Vol 5, Issue 11
Abstract
Introduction: Ossification of the Ligamentum Flavum (OLF) is a pathological ailment that affects the ligament and causes slowly progressive myeloradiculopathy in adults. Current study aimed to find out the Radiological and Pathological factors that are predictive of the surgical outcome of patients with OLF. Material and Methods: A prospective study of 31 patients studied for radio-pathological factors: number of segments affected by OLF, Sato’s CT–based classification, and the presence of intramedullary hyper-intensity on T2w MRI and CPPD Crystal deposition (pseudogout). All cases underwent decompressive laminectomies. Specimen sent for Polarizedlight microscopic studies and analyzed for characteristic rodshaped, birefringent CPPD crystals. Follow up done with a mean duration of 5 months. Recovery rate was calculated with pre-op and post-op “Modified JOA” scoring system. Results: Recovery was Excellent in 10 cases, Good in 6 cases, Fair in 12 cases, Poor in 3 cases. The author conducted a review of literature in English, Japanese and Korean literature and compared their studies. Conclusion: Early and correct diagnosis is required to avoid poorer results. Long-term follow up needed to determine the factors that predict the surgical outcome. This study also shows how this disease is highly under-reported in India
