Recurrent burner syndrome due to presumed cervical spine osteoblastoma in a collision sport athlete - a case report.

We present a case of a 35-year-old active rugby player presenting with a history of recurrent burner syndrome thought secondary to an osteoblastoma involving the posterior arch of the atlas. Radiographically, the lesion had features typical for a large osteoid osteoma or osteoblastoma, including osseous expansion, peripheral sclerosis and bony hypertrophy, internal lucency, and even suggestion of a central nidus. The patient subsequently underwent an en bloc resection of the posterior atlas via a standard posterior approach.

Thoracic paraparesis following an embolic vascular event during lumbar spinal surgery.

Objective: A case report illustrating the rare occurrence of thoracic paraparesis following the presumed occurrence of an embolic vascular event during lumbar spinal surgery is presented. The goal is to investigate the potential causes of acute postoperative paraparesis following lumbar spine surgery. A discussion of the symptoms, diagnosis, differential diagnosis, and management of spinal cord ischemia and postembolic infarction is presented.

Nucleus pulposus replacement: an emerging technology.

Debilitating low back pain as a result of symptomatic lumbar disc degeneration places a significant burden on an industrial society. Traditionally surgical treatment involving fusion of the anterior and posterior spinal elements has resulted in unpredictable and frequently irreproducible results, especially with regard to return to work rates. A new surgical method of managing symptomatic disc degeneration recalcitrant to nonoperative measures involves the partial or complete removal of the intervertebral disc with replacement with a motion-sparing device.
