Objective?To investigate the surgical methods and clinical results of repairing soft tissue defects in the thumb with distally-based dorsal thumb neurocutaneous vascular flap.?Methods?From January 2006 to October 2007, 23 patients with soft tissue defect in the thumb were treated, including 20 males and 3 females aged 19-46 years old (average 27.5 years old). The defect was caused by crush injury in 1 case, electric planer accident in 6 cases, incised injury in 8 cases, and avulsion injury in 8 cases. The defect was located on the palmar aspect of the thumb distal phalanx in 3 cases, the dorsal-radial aspect of the thumb distal phalanx in 3 cases, and ulnar or dorsal aspect in 17 cases. The defect size ranged from 3.3 cm × 1.2 cm to 4.2 cm × 1.2 cm. Among them, 18 cases were complicated with distal 1/2 nail bed defect or injury. The time between injury and hospital admission was 1- 72 hours (average 22 hours). During operation, the defect was repaired with distally-based dorsal-radial neurovenocutaneous vascular flap of the thumb in 3 cases and distally-based dorsal-ulnar neurovenocutaneous vascular flap of the thumb in 20 cases. The size of those flaps was 4.0 cm × 1.6 cm-5.0 cm × 3.0 cm. The donor site underwent direct suture or split thickness skin graft repair.?Results?At 10 days after operation, 3 cases suffered from the epidermal necrosis in the distal part of the flap, 2 of them experienced the exfoliation of dark scab 14 days later and the flap survived, and the flap of the rest one survived after dressing change. The other flaps and the skin graft at the donor site all survived uneventfully. The wounds healed by first intention. All the patients were followed up for 10-16 months (average 12.6 months). The flaps were soft in texture and full in appearance. The two-point discrimination value 6 months after operation was 8-10 mm. At 12 months after operation, the growth of the residual fingernail was evident in 18 cases, including 4 cases of curved or hook fingernail. Active flexion and extension of the thumb were normal. The abduction of the first web space reached or surpassed 80 percent of the normal side in 20 cases and was below 80 percent of the normal side in 3 cases. The clinical outcomes were satisfactory in 11 cases, approximately satisfactory in 8 cases, and unsatisfactory in 4 cases according to self-designed evaluation system.?Conclusion?The operative method of repairing the soft tissue defects in the thumb with the distally-based dorsal thumb neurocutaneous vascular flap is simple, stable in anatomy, in line with the principle of proximity, and suitable for repairing thumb tip defect 3 cm in size. It can bring a good postoperative appearance of the thumb and little influence on the hand function.

目的總結應用第2指蹼動脈蒂復合組織瓣修復示、中指指背復合組織缺損的療效。
方法2007年6月-2013年7月,采用第2指蹼動脈蒂復合組織瓣修復7例機器絞傷導致的示、中指指背復合組織缺損。男5例,女2例;年齡18~55歲,平均36歲。中指3例,示指1例,示、中指均有缺損3例。受傷至入院時間6~36 h,平均15 h。軟組織缺損范圍2.5 cm×1.0 cm~4.5 cm×1.5 cm。第2指蹼動脈皮瓣切取范圍為3.0 cm×1.5 cm~6.0 cm×2.0 cm。供區均直接縫合。
結果術后7例皮瓣均完全成活,供、受區切口均Ⅰ期愈合。患者均獲隨訪,隨訪時間11~13個月,平均12個月。皮瓣外形良好,末次隨訪時根據中華醫學會手外科學會上肢部分功能評定試用標準評定手指總主動活動度均達優。供區遺留線性瘢痕。
結論第2指蹼動脈蒂復合組織瓣修復示、中指指背復合組織缺損具有手術操作簡便、療程短、皮瓣血供可靠等優點,術后手指外觀及功能良好。
