掌长肌腱转位重建屈肌支持带的临床应用

Clinical application of the reconstruction of flexor retinaculum by transposition of palmaris longus muscle tendon

目的:介绍用掌长肌腱逆行转位重建屈肌支持带的方法。方法:应用掌长肌腱逆行转位,折返、重叠、编织等方法,在涉及屈肌支持带延长、松解、缺失等术式中重建屈肌支持带21例(23侧)。结果:本组重建屈肌支持带21例(23侧)全部成功,随访16例(18侧),在对抗强阻力下屈曲腕关节无一例出现腕部"弓弦畸形"及肌力减低,正中神经卡压等情况。肌腱按TAM评价法评定:总优良率88.9%。结论:掌长肌腱转位重建屈肌支持带是一种简便易行,疗效确切的方法。

Objective： To introduce the reconstruction of flexor retinaculum by transposition of palmaris longus muscle tendon. Methods： Refering to extension, looseness, absence of flexor retinaculum, the reconstruction was done by retrograde transposition, tucking, overlapping and weaving of the palmaris longus muscle tendon. Results： 21cases （23 sides） of the reconstruction of flexor retinaculum were involved. 16 cases （18sides） were followed up and proved that, under strong counterwork, no case appeared bow-string effect, muscle strength impairment and median nerve entrapment syndrome. According to the evaluation of TAM scales, excellent and good results were achieved in 16 sides （88.9%）. Conclusions： Transposition of palmaris longus muscle tendon is a simple and effective way on reconstructing flexor retinaculum.
