Acromioclavicular dislocation with adjacent clavicular fracture in a horseback rider

This report describes an unusual injury--complete acromioclavicular dislocation with midshaft clavicular fracture. The treatment decisions involved how best to treat a floating section of bone largely stripped of its soft tissue attachments. By a limited exposure, the acromioclavicular joint was reduced and pinned. The clavicle was then treated closed, obviating the need for additional soft tissue stripping and loss of blood supply. The successful outcome suggests this approach is effective in cases of this type.
