Abstract

This clinical study was performed to evaluate the effect of narrowing of spinal canal and calcified mass size on clinical manifestation in patients with ossification of posterior longitudinal ligament. Among cervical myelopathy patients with ossification of posterior longitudinal ligament in plain film and C-spine CT at Seoul National University Hospital From Mar. 1984 to Feb. 1986. All patients were male, ages ranging from 37 to 67 years. Ossified mass size and spinal canal AP diameter were measured in CT film. Patients were grouped by their functional status as Group I and Group II. Ossified mass size was markedly larger in disabled patients but spinal canal AP diameter excluding ossified mass was not so different. Actual AP diameter of spinal canal also markedly decreased in disabled patients. It seemed, therefore, that calcified mass size and actual spinal canal AP diameter had more significant effect on symptom and disability.
