In this article, the clavicle trimming of the research object was carried out, and the acromioclavicular ligament and the coracoclavicular ligament were completely retained. The modified acromioclavicular joints were randomly divided into groups according to the random allocation principle. A multifunctional strength machine was used as the experimental equipment and the load was 100mm / min. Speed, the tensile mechanics of the ligaments of the subject was measured, and the fracture strength and deformation of each ligament were recorded in detail on a computer connected to a biomechanical testing machine. When the ligament of group A was stretched at 100mm / min, the average breaking strength was 645.99N. When the ligaments of group B were stretched at 100mm / min, the average fracture strength was 551.33N, indicating that the strength of the coracoclavicular ligament is far less than that of the acromioclavicular ligament, but it has a little stabilizing effect in maintaining the stability of the clavicle. The experiments in this paper show that by comparing the tension between the acromioclavicular ligament and the coracoclavicular ligament, the results show that the acromioclavicular ligament can significantly maintain the stability of the acromioclavicular joint.
