The unstable shoulder girdle: early functional treatment utilizing open reduction and internal fixation.

The unstable shoulder girdle--a combination of a scapular neck fracture with a clavicular fracture, acromioclavicular dislocation, or sternoclavicular dislocation--represents a rare and often underestimated injury. Sufficient treatment to permit early function is necessary to avoid a frozen shoulder as well as to treat concomitant thoracic injuries. This is possible only by open reduction and internal fixation. In most cases this can be achieved by a sole osteosynthesis of the clavicular injury. We retrospectively analyzed 12 cases and classified the results according to the Constant Score. This analysis showed excellent functional results in nearly all cases.
