Anatomical study of the palmar intermetacarpal perforator flap.

The authors present an anatomical study of a small flap that may be harvested from any of the palmar intermetacarpal spaces while performing fasciectomy in Dupuytren's contracture. The flap is diamond-shaped, vascularised by two perforating branches originating from the underlying true digital arteries and may be rotated through 90 degrees to 180 degrees in either direction to provide skin cover and subcutaneous padding over the distal palm and/or the base of the finger.
