Volar Metacarpophalangeal Dislocation of Fingers: Review of the Literature.

Isolated volar metacarpophalangeal dislocations of fingers are extremely rare. There are few cases published in English and French literature. In this article, we aim to review the literature and present a case of isolated open volar dislocation of a finger. We treated this dislocation first by a dorsal approach alone and later, after recurrence, using a combined dorsal and volar approach. This report emphasizes the pathology of such injuries, clarifies the mechanisms, and outlines the treatment options of the dislocations. Close reduction can be achieved and maintained if done early. It must be attempted first for all cases. In irreducible or reducible but unstable dislocations, we recommend surgical restoration. During an open reduction, the major torn or avulsed soft tissue joint stabilizers must be repaired. A combined dorsal and volar approach, starting dorsally, is useful.
