Synchronous Vertebral Decompression and Posterior Stabilization in the Treatment of Spinal Malignancy

Thirty-four patients with metastatic tumors of the spinal column exhibiting vertebral collapse and posterior element disease were treated by a single-stage operation combining decompression of the vertebral body with posterior spinal instrumentation. Attention is drawn to the use of computed tomographic scanning in planning the operative approach. The indications for surgery were neurological deficit in 32 patients and pain in 2; 14 patients received preoperative radiotherapy. Of the 21 patients who were nonambulant preoperatively, 67% walked again, 21% regained sphincter control, and 68% had less pain. The surgical mortality was 12%; wound infection and dehiscence occurred in 15%. These results indicate that a single-stage decompression and posterior stabilization may improve neurological function dramatically in patients with malignant cord compression. The operative morbidity and mortality is comparable to that of laminectomy.
