【摘要】：目的探讨应用单、双和三枚Endobutton术式重建喙锁韧带术后稳定性的生物力学差异。方法 40具新鲜冷冻肩关节标本按随机数表法随机分为4组,每组10具。将标本进行解剖处理,保留肩胛骨-喙锁韧带-锁骨结构。前3组为实验组(组1、组2、组3):将喙锁韧带切断后分别应用三种Endobutton固定术式重建;第4组为对照组(组4):即原喙锁韧带。处理后行垂直方向生物力学拉力实验,记录造成喙锁结构失效的最大拉力值。结果喙锁结构破坏时各组拉力值分别为:组1(597.10±65.58)N;组2(750.67±51.00)N;组3(774.82±64.94)N;组4(645.44±43.37)N。组1所承受的最大拉力略低于组4(P0.05);组2和组3所承受的最大拉力明显高于组4(P0.05);组3所承受的最大拉力值略高于组2(P0.05)。结论三种Endobutton术式均可用于喙锁韧带重建,双Endobutton和三Endobutton术式垂直稳定性优于单Endobutton术式,双Endobutton术式和三Endobutton术式垂直稳定性相似。
[Abstract]:Objective to investigate the biomechanical differences of the stability of coracoclavicular ligament reconstruction with single, double and three Endobutton procedures. Methods 40 fresh frozen shoulder specimens were randomly divided into 4 groups, 10 in each group. The specimens were dissected to preserve the scapular-coracoclavicular ligament-clavicle structure. The first three groups were experimental group (group 1, group 2, group 3): the coracoclavicular ligament was reconstructed by three kinds of Endobutton fixation after transection, and the fourth group was the control group (group 4): the proto-coracoclavicular ligament. After treatment, vertical biomechanical tension experiments were performed to record the maximum tensile force of beak lock structure. Results the tensile strength of each group was (597.10 卤65.58) N, group 2 (750.67 卤51.00) N, group 3 (774.82 卤64.94) N, group 4 (645.44 卤43.37) N, respectively. The maximum tension of group 1 was slightly lower than that of group 4 (P0.05); the maximum tension of group 2 and group 3 was significantly higher than that of group 4 (P0.05); the maximum tensile force of group 3 was slightly higher than group 2 (P0.05). Conclusion all three Endobutton procedures can be used to reconstruct the coracoclavicular ligament. The vertical stability of double Endobutton and three Endobutton is superior to that of single Endobutton. The vertical stability of double Endobutton and triple Endobutton is similar.
