title: [Dumbbell-shaped double-leaf flap for the repair of penetrating wound of palm with tissue defect].
abstract: The penetrating wound of palm with the defect of tissues was usually caused by blunt crushing of gun-shot injury. It was difficult to treat clinically. In order to repair the skin defect of palm and dorsum in one operation, 2 kinds of dumbbell-shaped double-leaf flap were desigened. From February 1993 to March 1996, 5 cases with penetrating wound of palm were treated by this method in which the interosseous posterior artery flap in 4, and the superficial epigastric flap in 1. There were 4 males and 1 female with the ages ranging from 15 to 47 years old. The results were as follows: total survival of the flap in 4 cases and partial necrosis of skin margin of the distal leaf in 1 case. The appearance and function of the flap were satisfactory after a follow-up from 4 months to 3 years. It was concluded that the interosseous posterior artery flap had a long vascular pedicle with its constant anatomical distribution, and the 2nd stage of division of the pedicle of the flap was not necessary. It was a perfect flap in repairing the penetrating wound of the palm with small skin defect. The superficial epigastric flap was cumbersome in appearance and was necessary to divide the pedicle of the flap in 2nd staged operation. It was suitable in repairing the penetrating wound with large skin defect. Regarding the operative technique, a meticulous debridement and the appropriate flap area were required, and the blood vessel of the flap should not be compressed by the surrounding tissues. The advantages of this operation provided a simple method to handle, high rate of survival, and one-staged operation.
