目的　探讨改良指蹼动脉穿支链掌背皮瓣修复手指创面的可行性。 方法   2009年9~2012年9月，对我们收治25例手指创面患者，采用改良指蹼动脉穿支链掌背皮瓣修复并进行随访。结果  术后皮瓣顺利成活，3例皮瓣远端出现张力性水泡，经换药后治愈，18例获随访，随访6～18个月，平均12个月。皮瓣外形良好，手指伸屈功能无障碍，皮瓣两点辨别觉8~10 mm。根据中华医学会手外科学会上肢部分功能评定试用标准评定手指主动活动度，优15例，良2例，可1例，优良率94 %。结论    改良指蹼动脉穿支链掌背皮瓣可修复手指近节及中远节较大创面，手术简单、血供可靠。可制成复合组织瓣一期修复肌腱及骨的复合组织缺损。

Objective  To investigate feasibility of the clinical application of modified fingerweb perforator artery chain-like dorsal metacarpal flap for finger wound repairing.  Methods   Our department treated 25 cases of finger wounds in patients from Sep. 2009 to Sep. 2012 .The modified fingerweb perforator artery chain-like dorsal metacarpal flap was used to repair finger wounds and the patients were followed up.Results   The flaps survived successfully, tension blisters appeared on distal ends of flaps 3 cases, which subsided after dressing changes; 18 cases were followed up for 6 to 18 months with an average of 12 months. The flaps grew in good shape, no dysfunction was found in finger flexion, two-point discriminations were 8 - 10mm. The initiative activities of the fingers were evaluated according to Upper Extremity Evaluation Trial Criteria of Hand Surgery Society of Chinese Medical Association, 15 cases got A, 2 cases got B, 1 case got C, the good rate was 94%.  Conclusion   The clinical application of modified fingerweb perforator artery chain-like blood-supply dorsal metacarpal flap is suitable for repair of larger wounds in proximal middle and distal segments of fingers and has advantages of being easy in operation and reliable in blood supply. It can be used to prepare composite tissue flaps for primary repair of tendon and bone tissue defects..
