Summary
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 as well as the stiffness of the implants were determined. 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 can be avoided with this method while the other implants showed various disadvantages. From a biomechanical point of view, a carbon fibre ligament replacement provides sufficient stability in cases of chronic acromio-clavicular separation.
