Arthropathy, Neurogenic

**Definition:** Chronic progressive degeneration of the stress-bearing portion of a joint, with bizarre hypertrophic changes at the periphery. It is probably a complication of a variety of neurologic disorders, particularly TABES DORSALIS, involving loss of sensation, which leads to relaxation of supporting structures and chronic instability of the joint.
