Abstract: The present invention provides an acromioclavicular stabilizer including a waist band, a shoulder strap, a pad carried by the strap for positioning in the location of the acromioclavicular joint and an elbow cuff removably coupled to the waist band or shoulder strap. The present invention is adapted for non-surgical or post-operative care for reducing anatomically deforming forces present in AC separations or dislocations, and is convertible from a sling and stabilizer configuration to a stabilizer only configuration.
