改良M-Tang法阶梯式缝合技术在Ⅱ区指深屈肌腱修复中的应用

Application of Improved M-Tang Stepwise Suture Technique in the Repair of ZoneⅡDeep Finger Flexor Tendon

目的:分析改良M-Tang法阶梯式缝合在Ⅱ区指深屈肌腱修复手术中的应用效果。方法:选取2021年1月-2023年12月笔者医院收治的178例(共220个伤指)Ⅱ区指深屈肌腱损伤患者,按随机数字表法将伤指分为对照组(n=110)与观察组(n=110)。对照组采用津下缝合技术,观察组采用改良M-Tang法阶梯式缝合技术。统计比较两组手术时间、住院时间、患者满意度及术后1个月的手指主动关节活动度和手功能障碍评分。结果:观察组手术时间短于对照组(P<0.05),两组住院时间及患者满意度比较差异无统计学意义(P>0.05)。观察组总主动关节活动度优良率明显高于对照组(P<0.05);观察组近侧及远侧指间关节活动度优于对照组(P<0.05),两组掌指关节活动度比较差异无统计学意义(P>0.05);观察组手功能障碍程度评分低于对照组(P<0.05)。结论:改良M-Tang法阶梯式缝合技术在Ⅱ区指深屈肌腱修复中效果良好,能够改善手指主动活动范围与手功能,值得推广应用。

Objective To analyze the effect of the improved M-Tang ladder suture in the repair surgery of the flexor digitorum profundo's tendon in zoneⅡ.Methods A retrospective analysis was conducted on 178 patients(220 injured fingers)with deep flexor digitorum tendon injury in ZoneⅡof the author's hospital from January 2021 to December 2023.The injured fingers were divided into a control group and an observation group using random number method,with each group consisting of 110 fingers.The control group was treated with Tianjin suture technique,while the observation group was treated with improved M-Tang stepwise suture technique.The operation time,length of hospital stay,patient satisfaction,finger active joint range of motion and hand dysfunction score at 1 month after operation were compared between the two groups.Results The operation time of the observation group was shorter than that of the control group(P<0.05),and there was no significant difference in hospitalization time and patient satisfaction between the two groups(P>0.05).The excellent and good rate of total active joint activity in the observation group was significantly higher than that in the control group(P<0.05).The proximal and distal interphalangeal joint range of motion in the observation group was better than that in the control group(P<0.05),and there was no significant difference in the metacarpophalangeal joint range of motion between the two groups(P>0.05).The score of hand dysfunction in the observation group was lower than that in the control group(P<0.05).Conclusion The improved M-Tang stepwise suture technique has a good effect on the repair of the deep flexor tendon in zoneⅡ,which can improve the active range of finger movement and hand function.
