Hamatolunate impingement is an uncommon cause of ulnar-sided wrist pain. The condition occurs most commonly in wrists where there is type II lunate morphology (existence of a medial facet on the distal lunate for articulation with the hamate). Repeated impaction of the opposing articular surfaces particularly during ulnar deviation is thought to lead to chondromalacia and ultimately degenerative joint disease. Approximately 50% of lunate bones have type II morphology and about one fourth of these show loss of cartilage. Surgical management via arthroscopic burring of the apex of the hamate shows good short-term results.
