目的　探讨指背皮支链皮瓣修复手指背侧组织缺损的手术方法和疗效。  方法　应用指背皮支链皮瓣修复手指背侧组织缺损10例，切取皮瓣面积 1.0 cm×1.5 cm~2.0 cm×3.0 cm。   结果　术后仅1例远端出现表皮积液，经相应处理，皮瓣均成活，术后随访3~12 月。皮瓣修复后手指外形美观，转移皮瓣外观良好，色泽自然，质地柔软，不臃肿，手指各关节活动功能优良。  结论　指背皮支链皮瓣血供恒定，不牺牲指动脉，皮瓣设计简易，切取方便，是修复手指背侧组织缺损的简单、安全、有效的方法。

Objective　To investigate the surgical method and efficacy of dorsal cutaneous branch-chain flaps in repairing dorsal skin defects of the finger.　Methods　Ten cases of dorsal skin defects of the finger were repaired using dorsal cutaneous branch-chain flaps, with a flap area of 1.0 cm×1.5 cm~2.0 cm× 3.0 cm.　Results　Postoperatively, only 1 case presented effusion at the distal epidermis. After drawing out effusions and wound dressing, all flaps survived. Postoperative follow-up was performed for 3~12 months. After flap repair, fingers showed good appearance. Flaps presented good appearance and color, pliability and no bloating, and all finger joints had good activity function.　Conclusion　The dorsal cutaneous branch-chain flap is characterized by stable blood supply, digital artery preservation, convenient design and simple harvest. Therefore, it is a simple and safe ideal method to repair dorsal skin defects of the finger.
