Discs can become damaged either through trauma or degeneration and can be a source of pain. If part of a disc moves out of its normal position it can cause pressure on the spinal cord or on the individual nerve roots that exit from the spinal canal at each vertebral level and cause arm pain. Over time, the body’s reaction to a disrupted disc is the formation of bone spurs called osteophytes which can also cause pressure on the spinal cord or nerve roots.
Anterior cervical discectomy and fusion is a surgical procedure that involves removing a damaged or degenerated cervical disc/s replacing it with a bone, plastic or metal spacer and bone graft or bone substitute. This causes fusion of the two adjacent vertebrae into one solid mass and relieve the symptoms.
