Coracoacromial refers to the anatomical relationship or ligament connecting the coracoid process to the acromion of the scapula. This structure forms part of the coracoacromial arch, which plays a critical role in stabilising the shoulder joint and preventing superior displacement of the humeral head. Clinically, the coracoacromial ligament is significant because it can contribute to shoulder impingement syndrome when thickened or ossified, leading to pain and restricted movement.
