Abstract
BackgroundThis study aims to evaluate the influence of stabilization of acromioclavicular (AC) joint dislocation through the modified Weaver-Dunn technique and coracoclavicular (CC) ligaments using the finite element method. The goal is to determine which surgical technique allows behavior that is most similar to the joint, guaranteeing the necessary stability without restricting joint movements for the considered conditions. MethodsThe analysis is based on the three-dimensional finite element models. The control group of this study is represented by a three-dimensional model of the whole structure based on finite element methods. FindingsThe finite element models showed the stress and displacement values found in the intact acromioclavicular joint and surgical procedures. It was concluded that transferring the coracoacromial ligament to stabilize the acromioclavicular joint did not have a positive impact on the outcome. InterpretationThe finite element analysis on the treatment of acromioclavicular dislocation presented here provides medical teams with new parameters for choosing a suitable surgical procedure in the occurrence of acromioclavicular dislocation. The development and validation of the finite element models allow the variation of the conditions and enables different surgical configurations to be simulated.
