Abstract:
In difficult cases of replantation following small finger avulsion injury, in which amputation occurs at the proximal interphalangeal joint, the ulnar parametacarpal island flap, rotated 180° (propeller flap), can be used as an alternative method for covering a skin defect of the proximal phalanx. This flap can prevent metacarpophalangeal joint dysfunction and additional finger shortening. We propose the use of an ulnar parametacarpal flap for this purpose and report the outcomes of two successful cases treated with this method and followed up for 12 months.
