BACKGROUND
Traumatic amputation of the digit requiring revision amputation at the level of the proximal phalanx provides the opportunity to improve flexor function via tenodesis of the remaining flexor digitorum superficialis (FDS) tendon. Salvage of the remaining FDS and performing flexor tenodesis to the proximal phalanx allows increased flexion at the metacarpophalangeal (MCP) joint.
METHODS
This series reviews FDS tenodesis, outlining its surgical technique with clinical and functional outcomes. Institutional review board-approved retrospective study was performed. Twelve digits in 8 patients were included.
RESULTS
Average flexion-extension arc of affected MCP joint was 82°, and average grip strength was 70% of unaffected extremity. No patients required revision surgery or revision amputation. One patient had a minor wound infection treated successfully with oral antibiotics.
CONCLUSIONS
FDS tenodesis is a reliable motion-preserving procedure for patients with amputations at the level of the proximal phalanx to maintain flexion at the MCP joint.
背景
手指创伤性截肢需要在近节指骨水平进行修正性截肢，这为通过保留的指浅屈肌腱（FDS）腱固定术来改善屈肌功能提供了机会。保留剩余的FDS并对近节指骨进行屈肌腱固定术可增加掌指关节（MCP）的屈曲度。
方法
本系列回顾了FDS腱固定术，概述了其手术技术以及临床和功能结果。进行了经机构审查委员会批准的回顾性研究。纳入了8例患者的12根手指。
结果
患侧MCP关节的平均屈伸弧为82°，平均握力为健侧肢体的70%。没有患者需要再次手术或修正性截肢。1例患者出现轻微伤口感染，经口服抗生素治疗成功。
结论
对于在近节指骨水平截肢的患者，FDS腱固定术是一种可靠的保留运动的手术，可维持MCP关节的屈曲。
