Volar perilunate dislocation of the carpus: a case report and elucidation of its mechanism of occurrence.

Perilunate dislocation is a rare injury. The dorsal type, in which the distal row of the carpus displaces posterior to the lunate, is more common; the volar dislocation of the carpus on the lunate is an extremely rare injury. In addition to a case report of this rare injury, a probable mechanism is described with cadaveric studies. The proposed mechanism, to the author's best knowlege, has not been reported or recognized in the English literature, previously.
