A biomechanical in vitro test was performed to determine the stabilizing effect of various implants for the surgical treatment of the torn acromioclavicular joint. In a specially designed testing device, plastic and cadaver specimens of the shoulder girdle were stressed in various ways. Different dislocations between the acromion and the clavicle and between the clavicle and the coracoid were determined, as well as the stiffness of the implants. A convenient stabilizing effect combined with less rigid fixation to secure the newly treated AC joint was provided by K-wire fixation with cerclage. Interfering shear and bending stresses could be avoided with this method, while the other implants showed various disadvantages. From a biomechanical point of view, a carbon-fiber ligament replacement provides sufficient stability in cases of chronic acromioclavicular separation.
进行了一项生物力学体外测试，以确定各种植入物对肩锁关节撕裂手术治疗的稳定效果。在一个专门设计的测试装置中，以各种方式对塑料和尸体肩带标本施加应力。确定了肩峰与锁骨之间以及锁骨与喙突之间的不同脱位情况，以及植入物的刚度。克氏针环扎固定提供了一种方便的稳定效果，同时固定刚度较小，以确保新治疗的肩锁关节。使用这种方法可以避免干扰性的剪切和弯曲应力，而其他植入物则显示出各种缺点。从生物力学角度来看，碳纤维韧带替代物在慢性肩锁关节分离的情况下提供了足够的稳定性。
