Total vertebral body and pedicle arthroplasty.

Two new spinal procedures, a total vertebral body replacement using a one-stage posterior approach, and artificial pedicle replacement for extensive decompression laminectomies, are performed with the aid of a special segmental spine plating system. These spine plates, with their unique individual pedicle screw placement, create immediate and totally-rigid fixation as well as segmental control of each vertebral body. Surgeons are now free to perform laminectomies to their fullest extent without the consequence of an uncorrected, unstable back. The purpose of the procedure is to permit the patient to recover without immobilization or prolonged bed rest, and to return to normal activity and work without pain. Three cases are presented to demonstrate potential surgical indications and techniques.
