Shoulder arthrodesis by external fixation.
The choice of pin site in shoulder arthrodesis after brachial plexus injury is important for efficient external fixation. The pins are inserted into the coracoid process from the anterior aspect and the scapular spine from the acromion. This insertion method holds the scapula more rigid and allows the patient to lie supine. Moreover, it makes it possible to correct the fixation angle after the operation. In 11 cases of brachial plexus injury, solid bony arthrodesis was obtained within three months.
