Artificial disc replacement (ADR) is a surgical procedure used to treat certain types of lower back pain caused by degenerative disc disease (DDD) in the lumbar spine. Degenerative disc disease occurs when the intervertebral discs between the vertebrae in the spine start to deteriorate, leading to pain, reduced mobility, and other symptoms.Not everyone is a suitable candidate for artificial disc replacement. Factors such as the extent of degeneration, the location of the affected disc, the patient’s overall health, and the presence of certain spinal conditions can influence whether ADR is recommended.
