| 摘 要： | 背景:研究表明喙锁韧带在维持肩锁关节的稳定性中起重要作用,因而重建喙锁韧带至关重要.目的:对比观察三重固定纽扣钢板重建肩锁关节复位的生物力学性能. 方法:采集新鲜肩关节标本15具,造成肩锁关节脱位,分别行三重固定纽扣钢板重建和双Endobutton钢板重建,进行生物力学应力分析,对照比较两者重建肩锁关节的性能和效果. 结果与结论:三重固定纽扣钢板技术在应力-应变关系中,强度比正常喙锁韧带和双Endobutton钢板分别高25%和15%,弹性模量分别高17%和14%,轴向刚度分别高24%和14%,差异均有显著性意义(P < 0.05). 结果提示,三重固定纽扣钢板重建肩锁关节的生物力学性能,在强度、刚度均远超过初始的喙锁韧带的生物力学性能,而三重固定纽扣钢板重建肩锁关节复位的性能和效果比双Endobutton钢板重建更具有力学上的优势.

| Abstract: | BACKGROUND:Coracoclavicular ligament plays an important role in maintaining acromioclavicular joint (ACJ) stability,thus,ACJ reconstruction is necessary.OBJECTIVE:To observe the biomechanics of acromioclavicular joint reduction using triple button plates.METHODS:Fifteen fresh shoulders were collected,prepared for ACJ dislocation,and reconstructed using triple button plate or double Endobutton.Biomechanical stress analysis was used to compare performances and the effects of two methods.RESULTS AND CONCLUSION... |
