Homodigital flexor digitorum superficialis transposition (HFT) is proposed as a new technique for A2-C1 pulley reconstruction. Flexor digitorum superficialis is transposed on the proximal phalanx and inserted on the pulley rims, crossing over flexor digitorum profundus and acting as a pulley.
The kinematic feasibility was investigated in a cadaveric bowstring model (after A2 and C1 pulley removal) on 22 fingers (thumb excluded).
HFT was effective in restoring the correct flexion of proximal and distal interphalangeal joints, compared to bowstring model. No adverse events were registered.
HFT is a feasible technique. Clinical application is encouraged.
同向指浅屈肌移位术(HFT)被提议作为一种用于重建A2 - C1滑车的新技术。指浅屈肌被移位至近节指骨并插入滑车边缘,跨过指深屈肌并起到滑车的作用。
在一个尸体弓弦模型(去除A2和C1滑车后)上对22根手指(拇指除外)进行了运动学可行性研究。
与弓弦模型相比,同向指浅屈肌移位术在恢复近端和远端指间关节的正确屈曲方面是有效的。未记录到不良事件。
同向指浅屈肌移位术是一种可行的技术。鼓励临床应用。
