目的介绍一个新的皮瓣供区一一前臂背桡侧逆行筋膜蒂岛状皮的瓣的临床应用价值．方法以骨间后动脉桡侧支为轴型血管设计前臂背桡侧逆行的膜蒂岛状皮瓣修复手部软组织缺损８例，皮瓣面积６ｃｍ×３ｃｍ～１４ｃｍ×６ｃｍ．结果８个皮瓣全部成活，创口一期愈合．结论前臂背桡侧皮具有血供丰富，切取方便，损伤小，皮瓣质地佳，可制成感觉皮瓣等优点．逆行转位可修复腕、手部的皮肤缺损，其旋转弧可达近指关节． Objective To introduce a new flap for regional clinical application of the flap of the dorsal radial fascia pedicel island. Methods 8 cases of soft tissue defects of the hand were repaired by the pedicle membrane flap pedicled with the dorsal radial artery on the radial artery of the interosseous artery. The flap area was 6cm × 3cm ~ 14cm × 6cm. Results All eight flaps survived and the wounds healed in the first period. Conclusion The dorsal radial forearm possesses the advantages of rich blood supply, easy excision, small injury, good flap texture and sensory flap. Retrograde transposition can repair the wrist, hand skin defects, the revolving arc up to the knuckles.
