With displacement of the humerus upward, fractures may occur in the acromion, acromioclavicular joint, clavicle, coracoid process, or humeral tuberosities. Extreme soft tissue damage occurs to the capsule rotator cuff, biceps tendon, and surrounding muscles. Clinically, the head rides above the level of the acromion. The arm is short and adducted to the side. Shoulder movement is restricted and quite painful.
Neurovascular complications are usually present.
Most of these cases were the result of convulsions or violent trauma. The diagnosis was missed for over 12 hours. The patient had no complaints related to the shoulders and was able to place both hands on her head and behind her back. Disclaimer Please honor our copyrights and disclaimer. All rights reserved.
