Spinal cord monitoring using SSEPs is an accepted adjunct in the surgical correction of spinal deformities, but does not directly assess motor function. Motor-evoked potentials have been introduced in an effort to meet this important need. In this series of 18 patients, the feasibility of intraoperative monitoring using transcranial magnetic motor-evoked potentials is documented. The potential value of this neurophysiologic monitoring technique, as well as the pitfalls in interpretation, are reviewed.

Anterior stabilization of thoracolumbar burst fractures using the Kaneda device: a preliminary report.
Anterior decompression and fusion is a valuable technique in the treatment of thoracolumbar burst fractures. Anterior instrumentation has evolved to correct deformity and stabilize the spinal segments during decompression and bone grafting as a single-stage procedure. One anterior device developed by Kaneda has been used in our institution since 1989. ⋯ In some patients, coronal plane deformity was created by the device. No effect on neurologic recovery could be shown with this small series. Perioperative complication rate was 30%, and 1 patient developed pseudarthrosis.

Thirty-one patients with unstable displaced pelvic or acetabular fractures were admitted and underwent an open reduction and internal fixation of their fracture. All patients were studied prospectively for the incidence of proximal deep vein thrombosis (DVT) utilizing venous duplex ultrasound. Duplex scans were repeated at 1 week postoperatively in all patients. ⋯ Two of the three positive scans were noted only on postoperative examination. The third scan was positive on the preoperative phase. Duplex ultrasound was easily applied and well tolerated by the multiply injured patient.
