【摘要】：目的探讨应用示指尺侧指固有神经及其背侧支移位修复拇指两侧指固有神经撕脱离断伤的临床疗效。方法 2007年1月—2015年5月,采用示指尺侧指固有神经及其背侧支移位修复23例拇指两侧指固有神经撕脱离断伤患者。其中男17例,女6例;年龄16~63岁,平均32岁。致伤原因:机器绞伤10例,电锯伤8例,坚锐物品剐伤5例。拇指完全撕脱离断8例,拇指不完全离断2例,拇指掌侧裂伤13例(合并屈肌腱断裂7例)。受伤至手术时间为1.0~3.5 h,平均2.2 h。结果术后患者切口均Ⅰ期愈合,10例再植拇指全部成活。23例患者均获随访,随访时间5个月~2年8个月,平均1年4个月。患指指腹感觉恢复良好,末次随访时两点辨别觉为3~9 mm,平均6.8 mm。按照中华医学会手外科学会上肢部分功能评定试用标准评价,拇指指腹感觉达S418例、S3+5例,示指尺侧感觉为S3。结论应用示指尺侧指固有神经及其背侧支移位修复拇指指固有神经撕脱离断伤,能恢复拇指指腹良好感觉,手术操作简便,疗效确切。
[Abstract]:Objective to investigate the clinical effect of the transposition of the ulna digital nerve and its dorsal branch in the repair of avulsion injury of the digital nerve on both sides of the thumb. Methods from January 2007 to May 2015, 23 patients with bilateral finger avulsion injury were repaired by transposition of ulna digital nerve and its dorsal branch. There were 17 males and 6 females with an average age of 32 years. The causes of injury were machine strangulation in 10 cases, chainsaw injury in 8 cases and sharp object wound in 5 cases. There were 8 cases of complete avulsion of thumb, 2 cases of incomplete amputation of thumb and 13 cases of palm laceration of thumb (7 cases complicated with rupture of flexor tendon). The time from injury to operation was 1.0 脳 3.5 h, with an average of 2.2 h. Results all the incisions healed in the first stage after operation, and all the 10 cases survived. All 23 cases were followed up for 5 months to 2 years and 8 months, with an average of 1 year and 4 months. The finger abdomen feeling recovered well, and the two point discrimination sense was 3 鈮，
