摘要
克氏针张力带是治疗髌骨骨折的首选治疗方法,但张力带原理却一直被错误解读。传统张力带原理认为张力带通过功能锻炼使骨折块的分离力转化压应力。但偏心固定和关节面开裂是其最大缺点,在静息和运动时都会使骨块分离,形成没有压力的裂隙。功能锻炼并不能使骨折块的分离力转化为压应力。
Kirschner＇s wire tension band was the first choice in the treatment of patella fracture. But the principle of tension band had been misunderstood for long time. In the traditional principle,it was believed that tension band could change the separating force between fracture fragments into compressing stress when exercising. Eccentric fixation and articular surface cracking were disadvantageous. These could make the fracture fragments separate either at resting or exercising,which cause the gaps without pressure. Thus excercising could not change the separating force into compressing stress.
