This study aimed to compare two different tendon grafting techniques for coracoclavicular ligament reconstruction from the data obtained using finite element analysis.
Three different finite element models of the shoulder girdle were formulated using computerized tomography images: the reference model, coracoid loop technique (CLT), and drilling technique (DT) model. In all these models, forces were applied to the clavicle along three axes (x, y, and z) of the trapezius and sternocleidomastoid muscles. Thereafter, data regarding the loading values of the tendon grafts, loads on the coracoid base, and coracoclavicular vertical distance were measured.
While the reference model yielded the lowest values for all the loading conditions as well as the shortest coracoclavicular distance, the DT model demonstrated the highest values for all the loading conditions and the largest coracoclavicular distance.
Different tendon grafting techniques may offer different loading values on both bone surface and tendon graft during coracoclavicular ligament reconstruction. The drilling technique may be associated with increased loading on the tendon graft and bone surface, causing further loss of reduction and consequent complications.
本研究旨在通过有限元分析获得的数据，比较两种不同的肌腱移植技术用于喙锁韧带重建的效果。
利用计算机断层扫描图像建立了三种不同的肩带有限元模型：参考模型、喙突环技术（CLT）模型和钻孔技术（DT）模型。在所有这些模型中，沿着斜方肌和胸锁乳突肌的三个轴（x、y和z）向锁骨施加力。此后，测量了肌腱移植物的加载值、喙突基部的负荷以及喙锁垂直距离的数据。
参考模型在所有加载条件下产生的数值最低，喙锁距离最短，而DT模型在所有加载条件下显示出最高的数值和最大的喙锁距离。
在喙锁韧带重建过程中，不同的肌腱移植技术可能在骨表面和肌腱移植物上提供不同的加载值。钻孔技术可能与肌腱移植物和骨表面的负荷增加有关，导致复位进一步丢失并引发并发症。
