OBJECTIVE: This study was performed to describe the clinical presentation, surgical outcome in @entity1 with symptomatic @entity602 caused by ossification of the yellow ligament (OYL). METHODS: The authors reviewed consequent 12 @entity1 in whom posterior decompressive laminectomies were performed for OYL from 1999 to 2005. Diagnostic imagings including simple radiographs, computed tomography and magnetic resonance images were performed in each case. The @entity1 were reviewed to evaluate the clinical presentation, surgical outcome and complications of the operation. RESULTS: In all @entity1 , OYL was located in the lower thoracic region and all @entity1 presented with @entity1183 on both limbs and @entity158 . Among them, 5 @entity1 presented with gait disturbance due to paraparesis and two @entity1 had @entity1690 . Decompressive laminectomy through a posterior approach using microscope resulted in improvement of symptoms in all @entity1 , but, recovery was incomplete in a half of the @entity1 . The mean postoperative Japanese orthopaedics association (JOA) score was 7.9 when compared with 4.9 in preoperative assessment and the mean recovery rate was 65%. Dural tear was noticed in four @entity1 , so dural repair was performed, but there were no @entity51 related to @entity130 . CONCLUSION: OYL is an uncommon cause of @entity602 but it can lead to debilitating thoracic @entity602 . Careful decompressive laminectomy can achieve favorable results.
