• The trapezoid ligament which runs from the medial border of the coracoid process to the trapezoid line at the inferior part of the lateral end of the clavicle. • The conoid ligament which is spanned between the base of the coracoid process and the conoid tubercle just medial to the trapezoid line. Movements in the acromioclavicular joint are directly related to those in the sternoclavicular joint and those of the scapula. This joint is also discussed inthe online chapter Applied anatomy of the shoulder. Movements in the sternoclavicular joint are possible around three axes: • Clavicular elevation and depression occur around an anteroposterior axis • Clavicular protraction – the lateral end of the clavicle moves forwards, and retraction – the lateral end of the clavicle moves backwards, around a vertical axis • Backwards and forwards rotation of the clavicle around its longitudinal axis.
