Direct trauma to the shoulder region, as in this case, is one of the major cause of scapular fractures. They usually are associated with other injuries:

• clavicle fracture (as in this case)
• rib fracture
• sternal fracture
• spinal fracture
• pneumothorax and/or pulmonary contusion
• brachial plexus injury

This case has no involvement of the glenoid, acromion, coracoid process, or humeral head.
