Abstract：
Background: The repair of zone 1 flexor tendon injury often relies on re-inserting the flexor digitorum profundus (FDP) tendon to the distal phalanx. The aim of this retrospective study is to compare outcomes at 12 weeks following traditional button-over-nail (BON) versus bone anchor (BA) repair of zone I FDP injury. Methods: Patients undergoing zone 1 FDP repair between April 2007 and September 2018 using a BON or a BA were included in the study. Patient demographics, complications, arc of flexion of distal (distal interphalangeal joint [DIPJ]) and proximal interphalangeal joint (PIPJ) and patient-rated outcomes were analysed. Results: Forty-three patients were included in the study: 21 in the BA group and 22 in the BON group. Good function was achieved by 20 patients in BA versus nine in BON. Complications occurred in five BA patients versus 10 BON patients. Patients achieved a mean active DIPJ flexion of 49° and 31° and PIPJ flexion of 92° and 57° in the BA and BON groups, respectively. Conclusion: Our study demonstrates better arc of motion, patient-rated outcomes and lower complications at 12 weeks after surgery in patients undergoing zone 1 FDP repair using a BA. Level of Evidence: Level III (Therapeutic).
摘要：
背景：1区屈肌腱损伤的修复通常取决于将指屈肌腱（FDP）肌腱重新插入远端指骨。这项回顾性研究的目的是比较传统的纽扣钉（BON）和骨锚（BA）修复I区FDP损伤后12周的结果。方法：在2007年4月至2018年9月期间使用BON或BA进行1区FDP修复的患者被纳入研究。患者人口统计学，并发症,分析了远端（远端指间关节[DIPJ]）和近端指间关节（PIPJ）的屈曲弧和患者评估的结果。结果：43例患者被纳入研究：BA组21例，BON组22例。BA患者20例，BON患者9例，功能良好。5例BA患者发生并发症，10例BON患者发生并发症。在BA和BON组中，患者的平均主动DIPJ屈曲为49°和31°，PIPJ屈曲为92°和57°。分别。结论：我们的研究证明了更好的运动弧度，在使用BA进行1区FDP修复的患者中，患者评估的结局和术后12周的并发症较低。证据级别：III级（治疗）。
