中文摘要：

目的：介绍我院自行研制的胫骨结节骨牵引防滑脱装置生物力学评价.方法：在12 具尸体 24 条胫骨行胫骨结节骨牵引,随机分成2组.观察组安装胫骨结节骨牵引防滑脱装置,对照组是普通的胫骨结节骨牵引.比较2组的抗拉伸、 抗弯曲,以及抗旋转强度.结果：生物力学测定观察组与对照组,抗弯曲强度无显著差异, 两者无统计学意义 （P=0.3419）;观察组抗拉伸强度明显增强, 统计学结果有显著意义（P〈0.05）.结论：我院自行研制的胫骨结节骨牵引防滑脱装置设计独特, 具有良好的抗拉伸、抗弯曲能力,值得临床推广.

英文摘要：

Objective：To introduce our hospital developed by biomechanical evaluation of tibial tubercle traction non - skid device. Methods ： In 12 bodies of 24 tibia line tibial tubercle traction, randomly divided into two groups. Experimental installation tibial tubercle traction non - skid device, control group is ordinary tibial tubercle traction. Compare two groups of the tensile, bending, and the rotation strength. Results： Of biomechanics determination of the experimental group and control group, the bending strength had no significant difference, the two have no statistical significance （P = 0. 3419 ） ;Experimental tensile strength enhanced obviously, statistical results have significant meaning （ P 〈 0.05 ）. Conclusion： Developed by our hospital tibial tubercle traction non - skid device design was unique, had good tensile strength, bending capacity, worth clinical promotion.
