✓ Synovial cysts of the ligamentum flavum, measuring 1 cm in diameter, caused compression of the lumbar nerve roots in four patients. The authors discuss the association of these cysts with advanced focal spondylosis, and speculate on their etiology.

✓ Two patients presenting with signs and symptoms suggestive of nerve root compression secondary to extradural masses were found to have ligamentum flavum hematomas. Both patients had neurological deficits preoperatively and regained normal function postoperatively. There was no significant antecedent injury in either case. The symptom course was longer than that for spontaneous epidural hematoma. In one case, there was remodeling of bone, initially suggesting either infection or tumor.

AbstractLigamentum flavum hematoma (LFH) is an extremely rare compressive epidural lesion of the spine. The clinical manifestations of LFH are similar to that caused by other more common pathologies of nerve root compression like disc herniation. In the diagnosis, magnetic resonance imaging (MRI) is very important but challenging due to the changing intensities of the hematoma in relation to the stages of the aging blood. Herein, we report a case of LFH compressing the spinal canal in a 60-year-old man with pars interarticularis defect. He presented with low back pain radiating to the left leg. The neurological examination was consistent with left S1 nerve root compression. The MRI revealed a left posterior epidural mass compressing the thecal sac and S1 nerve root at the left L5–S1 level near the pars interarticularis defect. After surgical removal of the lesion, histopathological examination confirmed the diagnosis of LFH. Following surgery, he recovered rapidly. LFH due to spinal instability is important in terms of the understanding of the pathophysiological mechanisms related with LFH.

Cervical Spine Fusion

Abstract After spontaneous remission of nerve root compression, a myelographic defect may persist. Similarly, myelopathy may remain nonprogressive for long periods despite appreciable myelographic deformity. Although operation may arrest or improve the symptoms of cervical disc lesions and spondylosis, the ultimate confirmation that entrapped neural elements have been relieved permanently can only be provided by postoperative myelography. Preoperative and postoperative myelography documents the significant improvement that can be achieved by using posterolateral and posterior approaches to the cervical spine in patients with nerve root or spinal cord compression. The results in this group of patients were achieved with none of the disadvantages or complications of cervical spine fusion or of the interbody removal of cervical disc tissue, also leading to cervical fusion.
