Reconstruction of a tendon defect is a challenging task in hand surgery. Delayed repair of a ruptured flexor pollicis longus (FPL) tendon is often associated with tendon defect. Primary repair of the tendon is often not possible, particularly after debridement of the unhealthy segment of the tendon. As such, various surgical treatments have been described in the literature, including single-stage tendon grafting, 2-stage tendon grafting, flexor digitorum superficialis tendon transfer from ring finger, and interphalangeal joint arthrodesis. We describe step cut lengthening of FPL tendon for the reconstruction of FPL rupture. This is a single-stage reconstruction without the need for tendon grafting or tendon transfer. To our knowledge, no such technique has been previously described.
在手部外科手术中，肌腱缺损的重建是一项具有挑战性的任务。拇长屈肌腱（FPL）断裂的延迟修复常伴有肌腱缺损。肌腱的一期修复往往无法实现，尤其是在对肌腱不健康部分进行清创之后。因此，文献中描述了各种手术治疗方法，包括一期肌腱移植、二期肌腱移植、从环指进行指浅屈肌腱转移以及指间关节融合术。我们描述了用于重建FPL断裂的FPL肌腱阶梯式延长术。这是一种无需肌腱移植或肌腱转移的一期重建手术。据我们所知，此前尚未有过这样的技术描述。
