Disc replacement surgery (arthroplasty) involves replacing a herniated intervertebral disc (lumbar or cervical) with a prosthesis designed to retain the mobility of the spine. The goal of disc replacement is to reduce pain and neurological symptoms associated with nerve root or cord compression. The disc prosthesis is designed to re-establish the original disc height and emulate the natural biomechanics and movement of the spine. Disc replacement is an option for certain patients when non-surgical measures have failed to resolve or reduce symptoms.
Procedure
During the disc replacement surgery, a small 3-to-4 centimetre incision is made in the front of your neck to access your cervical spine. For the lower back the incision is given from the front usually. The damaged disc is removed and the impinged nerve is then relieved. The disc prosthesis is then inserted into the disc space using specialized and precise instruments. After the new disc is successfully placed, the incision is closed.
