A dynamic myocutaneous flap for hand reconstruction.
Relocation of functional units by neurovascular pedicle transfer is firmly established in reconstructive hand surgery. Transfer of muscle and overlying skin, the myocutaneous flap, to provide skin cover is equally established. The dynamic myocutaneous flap is an extension of these concepts. Injection studies confirmed that the abductor digiti quinti muscle and its overlying hypothenar skin could be transferred on its neurovascular bundle. This dynamic myocutaneous flap was used to reconstruct both skin cover and functional opposition following resection of an arteriovenous malformation involving the thumb. Other clinical applications would include reconstruction of thenar skin and muscle lost secondary to electrical burns, avulsion, or tumor resection.
