Simultaneous ipsilateral proximal interphalangeal and metacarpophalangeal dislocation of the fifth phalanx: A case report.

Introduction: There is no case of simultaneous ipsilateral proximal interphalangeal and metacarpophalangeal dislocation of a finger in the literature.

Case Presentation: A 61 years old male patient sustained an ipsilateral dorsal dislocation of the PIP joint of his fifth finger and dorsal dislocation of the metacarpophalangeal joint. Closed reduction of proximal interphalangeal joint was achieved while open reduction of the metacarpophalangeal joint was carried out.

Conclusion: The single most important element preventing reduction of the metacarpophalangeal joint was an interposition of the volar plate between proximal end of the phalanx and the head of the metacarpal.
