髌骨骨折生物力学研究及治疗方法的评价

Biomechanical study and evaluation of therapeutic methods of patellar fracture

本文分析了髌骨及髌骨骨折采用改良强力带钢丝固定法的生物力学。对采用改良张力带钢丝固定治疗髌骨骨折６４例进行观察。根据生物力学的原理和临床观察结果显示，此术式具有骨折愈合快，关节功能恢复好等明显优越于其它诸多方法之特点。同时还介绍了用２枚空心螺丝钉加钢丝固定治疗髌骨横形骨折的新方法。

Patellar fracture usually occur under distraction,three point bending of the patellar and direct blows. Operative treatment is necessary in which displacement excessmore than 2mm and may include open reduction and internal fixation. We have presented a new technique for the stabilization of patellar fractures that has provided superior results of 64 cases in biomechanics and clinical study. Provisional stabilization of the fracture can usually be obtained with dirschner wires. Definitive fixation can be achieved with wires. The modified tension-band technique has provided the best stability and the tension -band technique is recommended.
