指骨缓慢延长治疗手指缺损

Phalanx-Lengthening Method in the Treatment of Amputated Fingers

采用指骨缓慢延长方法治疗79例(180只缺损手指),使残指延长1～3.2 cm,平均2.2cm,通过对残指延长前后两点辨别觉、感觉神经传导速度及血氧饱和度的测定,证实以平均每天1 mm速度延长残指是安全的。可同时一次延长多个残指;延长时,相邻关节受到牵拉而不是挤压,从而避免了侧副韧带挛缩和关节面挤压性损伤;采用骨膜下截骨延长,保持了远期延长指长度。本法是治疗手指缺损的一种简单、安全、有效的方法。

79 cases (180 amputated fingers) underwent gradual distraction through phanlanges. The bone elongation obtained varied from 1 to 3.2 cm, with an average of 2.2 cm. Finger stumps were examined by measurement of 2 point discrimination (2PD) and sensative nerve conduction velocity as well as SO, both before and post lengthening. We confirmed that it was safe to distract the finger stump at a daily rate of 1 mm. Several fingers can be lengthened simultaneously using our device. The adjacent joint was also stretched other than compressed. Therefore, the lateral accessory ligament contraction and joint crush injury were avoided. The long-term length increase was maintained by subperiosteal osteotomy. Gradual finger lengthening is a simple, safe and effective method.
