The extended latissimus dorsi muscle island flap for flexion or extension of the fingers.

We describe the technique of transferring the latissmus dorsi muscle as an island flap for the restoration of digital flexion or extension in 28 patients. The latissmus dorsi muscle is raised down to the posterior iliac crest and prolonged with the gluteal superficial facia. We believe that this method is particularly suitable for extensive and prolonged paralysis of the lower elements of brachial plexus. It can be used also for severe Volkmann's contracture or the loss of flexor or extensor muscles of the fingers due to extensive debridement. The technique does not require microsurgery and there is no delay in reinnervation of the muscle. Copyright 2000 The British Society for Surgery of the Hand.
