Bone spurs most often form due to osteoarthritis. Damaged discs or joints lead to excessive movement in spinal joints. In order to compensate for this extra movement, the body forms osteophytes on the surfaces of the joints and along the edges of the vertebrae. Degeneration of the articular cartilages and intervertebral disks occurs as a result of normal aging processes. Poor posture and spinal injury can lead to bone spurs formation even at a young age.
