摘要
目的根据指伸肌腱止点的形态特点探讨其损伤分型与手术修复方法。方法依据将28例指伸肌腱止点区损伤情况分为带较大骨折块手指伸肌腱止点损伤、撕脱骨片小或骨折块粉碎无法固定及不带骨片的伸肌腱止点撕脱伤、靠近末节指骨基底背侧指伸肌腱腱性损伤3种类型。按损伤分型分别采骨块固定，末节指骨基底钻孔缝合固定及直接缝合修补等手术方法进行修复。结果28例无一例再度撕脱或断裂，其中3例远侧指间关节僵硬，其余25例远侧指间关节主动伸直受限度0°～10°，主动屈曲度30°～70°。结论根据伸肌腱止点损伤的分型，分别采用骨折块固定，末节指骨基底钻孔缝合崮定及直接修补缝合手术方法进行修复，方法简便，疗效可靠。
Objective To examine the methods of surgical repairs and clinical efficacy in the treatment of the extensor tendon insertion injury. Methods Twenty eight patients with finger extensor tendon insertion injury was categorized into 3 groups： fractures with large blocks, avulsion fracture of bone slices or small bone pieces without bone-crushing which can not be fixed, and tendinous injury at the insertion near the distal dorsal phalanx. The treatments were bone-fix, drilling-fix at the basement of distal phalanx, and direct suture, respectively. Results No re-avulsion or re-fraction occurred in these 28 patients. Stiffness of distal interphalangeal joint was observed in 3 patients. The remaining 25 patients had a limitation of initiative extension for the distal interphalangeal point 0°-10°, and initiative inflextion 30°-70°. Conclusions Targeted selections of bone-fix, drilling-fix at the basement of distal phalanx, and direct suture according to the types of injury are simple and effective in the treatment of insertion injury of digital extensor tendon.
