Open Reduction of Complex Metacarpo-phalangeal Joint Dislocations

Abstract

The metacarpophalangeal (MP) joint is resistant to injury due to its strong capsuloligamentous structures, which include the volar plate, deep transverse metacarpal and collateral ligaments. Complex MP joint dislocations are, by definition, irreducible by closed means and require open reduction, as the volar plate becomes entrapped between the metacarpal head and proximal phalanx. Two cases of isolated closed & one case of open complex dislocation of the metacarpophalangeal joint of the three different fingers are presented. Such dislocations require open reduction, and the dorsal approach is simple and effective.
