We reviewed 21 patients with 22 ruptures of the extensor pollicis longus at a mean of 5.3 years after transfer of the extensor indicis proprius tendon. Of these, 19 with 21 transfers described the result as good, and two as fair. The mean deficit of extension between the operated and unoperated thumbs was 1.4 cm, and the mean flexion deficit 0.6 cm. Pressure gauge measurements showed that the strength of the transfer was 51% of that of the uninjured extensor. The two fair results had an extensor lag of over 1.5 cm. Independent extension of the index was maintained in all patients, none having a discernible lag, but the strength of index extension was reduced to 49% of that of the normal finger. There was no evidence of functional loss. Extensor indicis proprius transfer for rupture of the extensor pollicis longus tendon is a simple and reliable procedure with few complications. It gives satisfactory long-term extension of the thumb.
我们回顾了21例患者，这些患者在示指固有伸肌腱转移术后平均5.3年发生了22次拇长伸肌腱断裂。其中，19例患者进行了21次转移，结果为良好，2例为一般。手术侧拇指与未手术侧拇指之间的平均伸展缺损为1.4厘米，平均屈曲缺损为0.6厘米。压力计测量显示，转移肌腱的力量为未受伤伸肌腱力量的51%。2例结果一般的患者伸肌滞后超过1.5厘米。所有患者的示指均可独立伸展，无一例有明显滞后，但示指伸展力量降至正常手指的49%。没有功能丧失的证据。对于拇长伸肌腱断裂，示指固有伸肌腱转移是一种简单可靠的手术，并发症少。它能使拇指获得令人满意的长期伸展效果。
