目的 探讨肘内侧小切口带血管尺神经前置的手术方法及治疗效果.方法 自2015年6月至2017年6月收治22例重度肘管综合征患者,根据手术方式不同分为带血管的尺神经筋膜下前置组和肘部小切口带血管的尺神经筋膜下前置组.参照上肢部分功能评定标准比较两组患者术后经肘关节尺神经传导速度、小指指腹两点分辨觉及术区切口长度.结果 22例患者随访8～15个月,平均12.2个月.带血管的尺神经筋膜下前置(对照组)优良率为82.29％,肘部小切口带尺侧下动脉的尺神经筋膜下前置手术组(研究组)优良率为80.91％.比较两组手术前后的尺神经传导速度变化和小指末节指腹两点分辨觉恢复差异无统计学意义(P＞0.05),采用肘内侧小切口后将平均13.4 cm的常规切口降至平均4.7 cm.结论 血管化的尺神经前置手术保证了肘局部尺神经的血供,是一种治疗重度肘管综合征的手术方式,在此基础上选择肘内侧小切口同样可达到常规手术切口长度的治疗效果,且小切口恢复快、术区美观.“,”Objective To investigate the surgical method and clinical efficacy ofvasculafized anterior subcutaneous transposition of the ulnar nerve with inferior ulnar collateral artery for treatment of severe cubital tunnel syndrome through minimal incision in the medial elbow.Methods From June 2015 to June 2017,22 patients with severe cubital tunnel syndrome were admitted and divided into two groups according to different surgical methods:the vascularized anterior subcutaneous transposition of the ulnar nerve and the vascularized anterior subcutaneous transposition of the ulnar nerve through minimal incision in elbow.The conduction velocity of ulnar nerve through elbow joint,the two-point discrimination of the distal pulp of the little finger and the length of incision were compared between the two groups.Results All the 22 patients were follow-up for 8 to 15 months,with an average of 12.2 months.The excellent and good rate was 82.29％ in the vascularized anterior subcutaneous transposition of the ulnar nerve group and 80.91％ in the group with minimal incision in elbow.There was no significant difference between the two groups in the changes of ulnar nerve conduction velocity before and after the operation and in the recovery of two-point discrimination of the distal pulp of the little finger.After using the minimal incision in elbow,the average conventional incision of 13.4 cm was reduced to 4.7 cm.Conclusion The vascularized anterior subcutaneous transposition of the ulnar nerve operation ensures the blood supply of the local ulnar nerve of the elbow.It is a kind of operation method for the treatment of severe cubital tunnel syndrome.On this basis,the selection of the minimal incision on the medial side of the elbow can also achieve the clinical efficacy of the conventional incision length.The minimal incision can recover more quickly and the appearance of operation area is better.
