串联手指侧方皮支链皮瓣修复手指贯通伤

Composite lateral finger flap for repairing penetrating injury of fingertip

目的：探讨利用串联手指侧方皮支链皮瓣修复手指贯通伤的临床疗效。方法：2009年8月～2015年6月对收治的15例手指贯通伤的患者采用串联的手指侧方皮支链修复掌侧及背侧贯通伤口创面，以手指指固有动脉背侧皮支为血运，在手指近节背侧设计2个串联的指动脉皮之链皮瓣修复2个缺损创面，切取皮瓣面积1．5cm ×2．5cm～2．5cm ×3．5cm，轴线为手指侧方正中，皮瓣蒂部带5．0～1．0mm宽的筋膜。供区直接缝合或取中厚皮片移植。结果：2例皮瓣术后出现水泡，经间断拆除皮瓣蒂部缝合线，水泡消失，其余皮瓣全部成活，术后随访6个月～1年，皮瓣外形质地满意，皮瓣两点分辨良好，患指屈伸功能恢复良好。结论：串联手指侧方皮之链皮瓣是修复手指贯通伤的理想方法。

Objective：To explore the effects of composite lateral finger flap for repairing the penetrating injury of the finger .Meth-ods：From August 2009to June 2015,the composite lateral Finger flap tiled in repair of the finger penetrating injury in 15 cases, skin of dorsal of fingers close quarter back side was designed into two composite cutaneous branches-chain flap to repair palmar and dorsal soft tissue defect of the finger, and based on digital proper artery, gutted flap range from 1.5cm ×2.5cm-2.5cm ×3.5cm, axis for the founder of the finger lateral, the width of the fascia range from 5.0-1.0mm was included in the flap pedicle division.The donor sites were repaired with the intermediate split thickness free skin grafts or direct suturing .Results：2 cases blisters appeared after operation, the symptoms relieved after removing the stitches at intervals in the flap pedicle division.All skin flaps were survived .All of the patients were followed up from 6 to 12 months after operation, all flaps presented the satisfactory appearance and texture ,recovered portective feel-ing, the flexion and extension function of wounded fingers recovered to normal .Conclusion：Use the composite lateral finger flap for re -pairing the penetrating injury of the finger might be an effective method.
