We present the unusual case of posttraumatic asymmetric bilateral shoulder dislocations in a woman in her late 70s - an inferior dislocation of the glenohumeral joint (luxatio erecta0 in the right shoulder and an anterior dislocation in the left shoulder. Bilateral shoulder dislocations and luxatio erecta dislocations are both rare by themselves, with only a few reported cases of each. To our knowledge, this is the first reported case of asymmetrical bilateral shoulder dislocations involving a luxatio erecta dislocation.

With appropriate treatment of an uncomplicated shoulder dislocation, and after reduction, patients should regain full function and strength. Our patient's ROM and strength - immediately and weeks after reduction - were limited, which suggests a possible complication of her injury. In surgical candidates, MRI should be ordered to evaluate for possible rotator cuff tear and other shoulder pathology.
