• ABSTRACT
    • The metacarpophalangeal (MP) joint is resistant to injury due to its strong capsuloligamentous structures, which include the volar plate and 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. The dorsal approach may offer the following advantages: 1) reduced risk to palmarly displaced neurovascular structures, 2) facilitated management of osteochondral fractures, and 3) full exposure of the volar plate. However, the dorsal approach requires splitting of the volar plate for adequate reduction, which may delay recovery.
