Cervical disc replacement is a surgical procedure that involves removing a damaged or degenerated cervical disc and replacing it with an artificial disc device. Cervical discs are the cushions or shock absorbers between the bones (vertebra) of the neck (cervical spine). Discs that become damaged either through trauma or degeneration can be a source of pain. If part of a disc moves out of its normal position it can cause pressure on the central spinal cord or on the individual nerve roots that exit from the spinal canal at each vertebral level. 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. Disc disruption and degeneration can be a source of neck pain as well as cause neurologic symptoms which may include pain, numbness or weakness that radiates from the neck into one or both arms.
