通道辅助微创与切开跟腱缩短术治疗陈旧性跟腱过长的疗效比较

目的 比较通道辅助微创跟腱缩短术与切开跟腱缩短术治疗陈旧性跟腱断裂愈合后跟腱过长的疗效.方法 回顾分析2013年12月-2015年12月符合入选标准的19例患者的临床资料,其中8例采用通道辅助微创跟腱缩短术,11例采用切开Krackow跟腱缩短术.两组患者性别、年龄、受伤至手术时间、术前小腿周径、术前美国矫形足踝协会(AOFAS)评分等一般资料差异无统计学意义(P>0.05),具有可比性.比较两组的手术时间、手术切口长度、术后住院时间,术后跟腱恢复情况,小腿周径和AOFAS评分.结果 微创组手术时间、手术切口长度及术后住院时间均显著少于切开组(P<0.05).术后8周随访时MRI显示两组患者跟腱均恢复连续性.两组末次随访时小腿周径和AOFAS评分均高于术前,差异有统计学意义(P<0.05),但两组间比较差异无统计学意义(P>0.05).结论 通道辅助微创缩短术治疗陈旧性跟腱断裂愈合后跟腱过长的疗效与切开跟腱缩短术相似,且具有手术时间短、切口小、住院时间短、可避免腓肠神经损伤等优点.

Effectiveness comparison of channel-assisted mini-incision and open Achilles shortening for treatment of healed Achilles tendon rupture

Objective To compare the clinical effectiveness between the channel-assisted mini-invasion and open Achilles shortening for treatment of the elongated Achilles tendon following previous rupture.Methods The clinical data of 19 patients admitted from Dec. 2013 to Dec. 2015 and met the inclusion criteria were analyzed retrospectively. Eight patients were treated with shortening operation by channel-assisted minimally invasive repair system, while 11 patients received dissection of Krackow Achilles tendon shortening. There was no significant difference between the two groups in gender, age, injury to operation time, preoperative calf circumference and preoperative AOFAS (American Orthopaedic Foot & Ankle Society) score (P>0.05).Results The operation time, incision length and postoperative hospital days were significantly less in min-invasion group than in incision group (P<0.05). After operation, wound healing by first intention was obtained in incision group except 1 case which got infection and healed by treatment 2 weeks later. No sural nerve and vascular injury and lower extremity deep vein thrombosis existed. MRI showed that the Achilles tendon recovered in both groups at the 8th week follow-up. The patients were followed up for 12-17 months in the mini-invasion group and 12-20 months in the incision group. The calf circumference and AOFAS score of both groups were higher in the last follow-up than that in pre-operation (P<0.05), but no significant difference existed between the two groups at the last follow-up (P>0.05).ConclusionChannel-assisted minimally invasive Achilles tendon shortening operation has not only similar effectiveness to the incision shorting operation for the treatment of elongated Achilles tendon following previous rupture, but also has the advantages of shortening operation time and stay in hospital and avoidance of sural nerve injury.
