Disc replacement or Disc Arthroplasty, is a treatment alternative to spinal fusion. Instead of fusing together a painful disc, an artificial prosthesis can be implanted. The theoretical benefits of disc replacement over fusion are the avoidance of extra stress around the spinal fusion and the preservation of motion in the spine that one loses when a disc space is fused.
This patient underwent a successful C5-6 Disc replacement (pictured left) rather than a cervical fusion. The patient had immediate relief of the right arm pain that bothered her preoperatively. She had normal range of motion of her neck after surgery.
