[Case of volar dislocation of 4 ulnar metacarpals]. / A propos d'un cas de luxation antérieure des quatre derniers métacarpiens.

ABSTRACT

A case of volar dislocation involving the four ulnar metacarpals treated by open reduction and fixation with Kirschner wires is reported. A review of the literature leads the authors to suggest several pathogenic hypotheses. The mechanism may be direct or indirect according to whether the trauma is sustained on the metacarpal heads or on the bases of the metacarpals. Emergency treatment by open reduction and fixation usually provides excellent results.
