Cross-Arm Double Flap in the Repair of Severe Adduction Contracture of the Thumb

Abstract

This paper describes the authors' technique of cross-arm, double flap for the repair of severe adduction contracture of the thumb. This technique has certain advantages over those previously described, the raw dorsal and volar regions are covered simultaneously and recurrent fibrosis is averted; risk or flap necrosis is minimal; intermetacarpal Kirschner wires are no longer required to maintain abduction from both the functional and aesthetic point of view, the results signal an advance in therapy (Figs. 12 and 13).
