title: Locking of the metacarpophalangeal joint.
abstract: Intrinsic finger metacarpophalangeal (MP) joint locking is infrequent, although not rare. Our experience and the recent literature suggest that metacarpophalangeal locking is being recognized with increasing frequency. The various mechanisms responsible for intrinsic finger MP locking, as well as the diagnosis and treatment of this condition, are reviewed. Four additional cases of the condition are presented.
