Aseptic necrosis of the metacarpal head was first reported by Dieterich1 in 1932. This is an uncommon problem, and there are only a few isolated case reports in the literature2-5. The symptoms range in severity; some patients are asymptomatic, while others have a complete collapse of the metacarpal head with a painful and restricted range of motion of the metacarpophalangeal joint6. Because of the limited experience with this problem, no single modality of treatment can be recommended as ideal.
