中文摘要:
      目的:从生物力学方面比较Tossy Ⅲ型肩锁关节脱位的3种不同固定方式,为临床治疗提供理论依据? 方法:取6具成人尸体标本(12个肩关节),均制成Tossy Ⅲ型肩锁关节脱位模型?将12个肩关节随机分为3组,每组4例,分别进行钛缆内固定?锚钉内固定?锁骨钩钢板内固定?术后用MTS生物材料测试系统对3种内固定标本分离度进行测量?结果:3种内固定方式均能够达到完好的解剖复位?与锁骨钩钩钢板内固定组相比,其余两组关节活动度较大(P < 0.05)),且移位程度较小(P < 0.05)?结论:对于Tossy Ⅲ型肩锁关节脱位,锚钉及钛缆内固定分离度较小,活动度适中,更接近于正常生理状态?
英文摘要:
      Objective:To compare the biomechanical aspects among the three different fixation methods of Tossy type III acromioclavicular joint dislocation,and to guide the clinical treatment. Methods:Six adult cadaveric specimens were used in the study (12 shoulders). and made to the Tossy type Ⅲ acromioclavicular joint dislocation model. The 12 shoulder were randomly divided into 3 groups with 4 cases in each group,and the three groups received titanium cable fixation,anchor screw fixation and clavicular hook plate fixation respectively. After fixation,MTS biological material testing system was used to test the degree of excursion of three kinds of internal fixation. Results:All of the three internal fixation methods can be anatomical reduction. Compared with clavicular hook plate internal fixation group,the degree of activity in other two groups is larger(P < 0.05),and the degree of separation is smaller (P < 0.05). Conclusion:Congared with Tossy type Ⅲ acromioclavicular joint dislocation,the degree of separation of itanium cable fixation and anchor screw fixation is small,and the degree of activity is moderate,more closer to normal physiological state.
