摘要

摘要: 目的探讨前臂外侧皮神经终末支营养血管皮瓣修复拇指指端、指腹创面的临床效果。方法采用回顾性观察性研究方法。2016年2月—2019年4月，唐山市第二医院收治符合入选标准的21例（21指）拇指指端、指腹创面患者，其中男13例、女8例，年龄21~65岁，缺损部位：指端14例、指腹7例，均存在骨骼和/或肌腱外露。本组患者清创后创面面积为2.0 cm×1.5 cm~4.0 cm×2.7 cm，均采用前臂外侧皮神经终末支营养血管皮瓣修复，皮瓣切取面积为2.3 cm×1.8 cm~4.3 cm×3.0 cm。术中将皮瓣携带的前臂外侧皮神经终末支与创面内指固有神经残端吻合，供区直接缝合。观察术后皮瓣成活、供区伤口愈合情况及随访时皮瓣和供瓣区外观。末次随访时，测量皮瓣静态两点辨别觉距离，参照Michigan手部功能问卷评定标准评估患者对患手外观满意度，测量患指与健侧拇指关节总主动活动度（TAM）及患手与健手虎口角。对数据行配对样本t检验。结果术后21例患者皮瓣全部成活，血运良好、无感染；供区伤口愈合。所有患者均获随访，时间8~22个月，皮瓣外形良好，颜色及质地与周围组织相近；指端及指腹无疼痛，皮瓣无异位感，拇指桡侧供区仅残留轻微线性瘢痕。末次随访时，本组患者皮瓣静态两点辨别觉距离为6~11 mm。18例患者对患手外观表示非常满意，3例患者对患手外观表示满意。本组患者患指TAM为（140±5）º、患手虎口角为（94±9）°，分别与健侧拇指的（141±5）°、健手的（95±9）°相近（t=-2.024、-1.142，P>0.05）。结论前臂外侧皮神经终末支营养血管皮瓣解剖恒定、操作简便，修复拇指指端、指腹创面后，拇指外形美观、功能恢复好，为拇指指端、指腹创面修复提供了一种较佳的治疗方法，尤其适合急诊开展。

Abstract: Objective To investigate the clinical effects of neurocutaneous vascular flap innervated by terminal branch of lateral antebrachial cutaneous nerve in repairing finger tip or finger pulp wounds of the thumb. Methods A retrospective observational study was conducted. From February 2016 to April 2019, a total of 21 patients (21 fingers) with finger tip or finger pulp wounds of the thumbs met the inclusion criteria and were admitted to the Second Hospital of Tangshan, including 13 males and 8 females, aged 21 to 65 years, with the defects located at the finger tips of 14 patients and the finger pulps of 7 patients, and all having exposed bones and/or tendons. The wound sizes of patients in this group after debridement ranged from 2.0 cm×1.5 cm to 4.0 cm×2.7 cm. All the wounds were repaired with the neurocutaneous vascular flap innervated by terminal branch of lateral antebrachial cutaneous nerve, with the flap sizes ranging from 2.3 cm×1.8 cm to 4.3 cm×3.0 cm. In surgery, the terminal branch of lateral antebrachial cutaneous nerve carried by the flaps was anastomosed with the end of the proper digital nerve of the wounds. The donor sites of flaps were sutured directly. The survival of flaps and healing of wounds in donor sites after operation were observed. The appearance of flaps and donor sites were observed during follow-up. At the final follow-up, the static two-point discrimination distances of the flaps were measured, and the degree of satisfaction of patients for the appearances of injured hands were evaluated based on Michigan Hand Function Questionnaire. The total action motion (TAM) of the injured and contralateral thumbs and the angle of thumb web of the injured and contralateral hands were measured. Data were statistically analyzed with paired sample t test. Results All the flaps of the 21 patients survived with good blood supply and no infection. The wounds at the donor sites were all healed. All the patients were followed up, with the time ranging from 8 to 22 months. The appearances of flaps were good with their color and texture similar to the surrounding tissue. There was no pain in the finger tip or finger pulp, nor any ectopic sensation in flaps. There was only some linear scar left at the radial side of thumb. At the final follow-up, the static two-point discrimination distances of the flaps of the patients were 6 to 11 mm; 18 patients were very satisfied and 3 patients were satisfied with the overall appearance of the injured hand. The TAM of injured thumbs and the angle of thumb web of the injured hands of the patients were respectively (140±5)º and (94±9)°, which were similar to (141±5)º of the thumbs and (95±9)° of hands in the contralateral side, respectively (t=-2.024, -1.142, P>0.05). Conclusions The neurocutaneous vascular flap innervated by terminal branch of lateral antebrachial cutaneous nerve has constant anatomy and is easy to perform. It can repair the finger tip or finger pulp wounds of the thumb achieving good appearance and function recovery. It provides a good option for repair of finger tip or finger pulp wounds of the thumb and is especially suitable for emergency application.
