目的 探讨指动脉背侧支带蒂皮瓣与V-Y推进皮瓣瓦合修复手指指端脱套伤及掌背动脉返支逆行带蒂岛状皮瓣接力修复近节背侧供区软组织缺损的效果。 方法 2016年6月—2019年1月,唐山市第二医院手外科收治21例第2~5指指端脱套伤患者,其中男14例、女7例,年龄24~60岁,进行回顾性临床随访研究。清创后创面面积为2.0 cm×1.5 cm~3.5 cm×2.2 cm。于患指近节背侧设计带指固有神经背侧支和指背神经的指动脉背侧支带蒂皮瓣修复患指末节背侧创面,皮瓣面积为1.6 cm×1.5 cm~2.6 cm×2.4 cm;于患指掌侧设计V-Y推进皮瓣修复患指末节掌侧创面,皮瓣面积为0.8 cm×0.6 cm~2.0 cm×1.5 cm。采用掌背动脉返支逆行带蒂岛状皮瓣修复近节背侧供区软组织缺损,皮瓣面积为1.8 cm×1.7 cm~2.8 cm×2.6 cm,手背皮瓣供区直接缝合。观察术后3种皮瓣成活情况及随访时皮瓣的血运、外观。末次随访,测量3种皮瓣静态两点辨别觉距离,采用Michigan手部功能问卷评估患者对手部外观的满意度,参照中华医学会手外科学会上肢部分功能评定试用标准评估患指关节总活动度。 结果 术后所有皮瓣完全成活,其中1个指动脉背侧支带蒂皮瓣表面出现张力性水疱,经拆除蒂部缝线、换药处理后创面愈合。随访6~20个月,平均12个月,3种皮瓣外形美观、质地柔软、色泽与周围组织相近,手背供区仅残留线性瘢痕。末次随访时,V-Y推进皮瓣静态两点辨别觉距离为4~7 mm,指动脉背侧支带蒂皮瓣静态两点辨别觉距离为5~10 mm,掌背动脉返支逆行带蒂岛状皮瓣静态两点辨别觉距离为8~15 mm。16例患者对手部外观非常满意,5例患者对手部外观满意;患指关节总活动度评定为优17例、良4例。 结论 指动脉背侧支带蒂皮瓣与V-Y推进皮瓣瓦合修复手指指端脱套伤及掌背动脉返支逆行带蒂岛状皮瓣接力修复近节背侧供区软组织缺损,手术方式简单可靠,患指外观、功能恢复良好,供区损伤小。
Abstract:Objective To investigate the effects of the dorsal branch of digital artery pedicled flap combined with V-Y advancement flap for repair of degloving injury of fingertip and reverse dorsal metacarpal recurrent artery pedicled island flap for relaying repair of the soft tissue defects in the donor sites of the proximal dorsum. Methods A total of 21 patients with degloving injuries of fingertips at the 2nd to 5th fingers were hospitalized in the Department of Hand Surgery of the Second Hospital of Tangshan from June 2016 to January 2019, including 14 males and 7 females aged 24-60 years. The retrospective clinical follow-up study was conducted. The areas of wounds after debridement ranged from 2.0 cm×1.5 cm to 3.5 cm×2.2 cm. The dorsal branch of digital artery pedicled flaps with dorsal branch of the proper digital nerve and dorsal digital nerve were designed in the proximal dorsum of the affected fingers to repair dorsal wounds in the distal dorsum of the affected fingers, and the sizes of the flaps ranged from 1.6 cm×1.5 cm to 2.6 cm×2.4 cm. The V-Y advancement flaps in the palmar side of the affected fingers were designed to repair palmar wounds in the distal segment of the affected fingers, and the sizes of the flaps ranged from 0.8 cm×0.6 cm to 2.0 cm×1.5 cm. The reverse dorsal metacarpal recurrent artery pedicled island flaps were used to repair the soft tissue defects in the donor sites of proximal dorsum, the sizes of the flaps ranged from 1.8 cm×1.7 cm to 2.8 cm×2.6 cm, and the donor sites of the flaps in back of hand were sutured directly. The survivals after the operation and the blood supply and appearance during follow-up of the three flaps were observed. At the final follow-up, the static two-point discrimination distance of the three flaps was measured, the satisfaction degree of patients for the appearance of hand was evaluated based on Michigan Hand Function Questionnaire, and the total active range of motion of the injured finger joints was assessed by the trial standard for the evaluation of the functions of the upper limbs of the Hand Surgery Society of the Chinese Medical Association. Results All the flaps survived after operation. Tension blisters appeared on the surface of one dorsal branch of digital artery pedicled flap, and the wound healed after removing the stitch at the pedicle and changing dressings. During follow-up of 6-20 months, with an average of 12 months, the three kinds of flaps had good appearance, soft texture, and similar color with surrounding tissue, and with only linear scars in donor sites of the dorsal hand. At the final follow-up, the static two-point discrimination distances of V-Y advancement flaps, dorsal branch of digital artery pedicled flaps, and reverse dorsal metacarpal recurrent artery pedicled island flaps were 4-7 mm, 5-10 mm, and 8-15 mm, respectively. Sixteen patients were strongly satisfied with the appearance of hand, and the remaining five patients were satisfied with the appearance of hand. The total active range of motion of the injured finger joints was evaluated as excellent in 17 cases, good in 4 cases. Conclusions The operation is simple and reliable for dorsal branch of digital artery pedicled flap combined with V-Y advancement flap to repair the degloving injury of fingertip, and reverse dorsal metacarpal recurrent artery pedicled island flaps to repair the soft tissue defects in the donor sites of the proximal dorsum, and the appearance and function of the affected fingers recover well, with minimal injury.
