A Biomechanical Model of the Shoulder Including Acromioclavicular Joint Ligaments: Preliminary Results

In this study an upper limb biomechanical model which includes strain-adjustable ligaments of the acromioclavicular joint was developed. The model including 7° of freedom is able to evaluate the movements of the shoulder, elbow and wrist. The ligaments strain can be adjusted in order to simulate different types of Rockwood acromioclavicular dislocation.
