Lumbar Corpectomy Surgery

The lumbar corpectomy is a procedure performed to relieve the pain caused when diseased or damaged vertebrae bone blocks and pinches nerve roots. It also corrects spinal column deformities.

During this procedure, the patient is positioned on his right side so the surgeon has access to the patient’s left side. The surgeon makes an incision and removes the diseased and damaged parts of the vertebral bone to relieve the pressure from the nerve roots. The discs above and below the affected vertebra are removed along with any diseased vertebral fragments. The bone surfaces are cleared and prepared to receive a bone graft. Bolts are screwed into the vertebrae above and below the gap to help the surgeon perform the rest of the procedure.

The surgeon then opens the vertebral space and corrects the spinal column curvature. This is known as reduction of deformity. While the vertebral space is open, the bone graft is inserted. Closing the vertebral space secures the bone graft tightly into place. A piece of metal called a Zplate is placed onto the two bolts, bridging the vertebrae levels above and below the bone graft. Two nuts hold the Zplate in place, and two additional screws are inserted. The Zplate keeps the area secure while the bone heals. During the healing process, the bone graft will knit with the vertebrae levels above and below to create one solid bone segment, known as a bone fusion.
