[Palmar dislocation of the metacarpophalangeal joint. A case report]

Palmar dislocation of the metacarpophalangeal joint of the long finger is a rare injury. The authors report a case of palmar dislocation of the metacarpophalangeal joint of the ring finger. The presumed mechanism is a combination of active flexion and forceful hyperextension. The dislocation was treated successfully by closed reduction shortly after injury. Closed reduction should be attempted in all cases of this injury.
