Twenty-two patients underwent surgical stabilization of thoracic and lumbar spine fractures. Twenty patients were operated on within 4 weeks of the injury and two patients more than 1 year following injury. Harrington rods were used in 21 and Dwyer instrumentation in one. The presenting neurological deficits were: four complete, five incomplete, and 13 intact. Clinical failure was noted in four patients, two of whom underwent posterior instrumentation more than 1 year following the initial injury. The most important contributing factor to failure was use of instrumentation in deviation from standard practice. The aim of operative treatment to maintain fracture reduction, decompress neural elements, promote fracture healing, and shorten hospitalization was achieved.
A case of a high division of the median nerve associated with a persistent median artery and three transligamentous thenar motor branches is presented. To our knowledge, three transligamentous motor branches have not been previously reported in the literature.
Six patients with a normal myelogram were found to have evidence of a herniated nucleus pulposus (HNP) at the L5-S1 level on computed tomography (CT) scan. In all six patients, the presence of the herniated disk was confirmed at surgery. Five of the six herniations were lateral. The authors found no patients with an abnormal myelogram and a normal CT at the L5-S1 level in a technically good study. The sensitivity of the CT in diagnosing an HNP at the L5-S1 interspace is greater than with myelography if images in the exact plane of the disk can be obtained.

The clinical histories of four patients with extreme lateral lumbar disc herniations are presented to demonstrate the ineffectiveness of myelography and the value of computed tomography.
