Is Coracoid Fracture With AC Dislocation An Unusual Case?

Abstract The coracoid process is the hook-shaped anterior process of the scapula, which runs cranially to the scapula and then to the anterolateral side. Its size, shape, and orientation vary from person to person. Coracoid fractures are rare. They can be missed on routine X-rays due to their anatomy. We present a rare case of fracture of the coracoid process and conservatively managed acromioclavicular joint dislocation. A 46-year-old day laborer presented to our emergency department with pain in his left shoulder and restricted movement following the traffic collision. The radiograph of the left shoulder demonstrated just AC joint dislocation. We ordered a CT scan of the shoulder based on the findings of the physical exam and a suspicious-looking X-ray. The CT scan revealed a minimally displaced coracoid fracture. Despite the concomitant dislocation, we managed the patient conservatively. After six weeks, the fracture had healed completely. The patient had a satisfactory outcome following rigorous physical therapy. Coracoid fractures are often overlooked due to their anatomical structure. We recommend specific shoulder x-ray views such as the scapula Y or axillary view to rule out a coracoid fracture. CT scan is considered to be the gold standard for diagnosis. Fractures can be treated conservatively or surgically, depending on the indication.
