Triple Disruption of the Superior Shoulder Suspensory Complex - A Case Report

Superior shoulder suspensory complex (SSSC) plays a key role in maintaining stable upper extremity- axial skeleton connection. Injury to one component is a common occurrence while double disruption leading to floating shoulder is a rare occurrence. Disruption of more than one component of this complex leads to significant morbidity and interferes with adequate shoulder function and requires surgical intervention.

This case report describes a rare triple disruption of SSSC in a 40-year female in dominant shoulder involving fracture of lateral end of clavicle, Type 1 coracoid fracture, and an acromion fracture. She underwent operative fixation of all the components and reported excellent functional outcome at the end of 1-year follow-up.

The triple disruption of the SSSC is an extremely rare injury comprising breakages of the ring at three distinct locations, which usually follow high-velocity injuries associated with other musculoskeletal and visceral injuries. Proper pre-operative evaluation and appropriate surgical intervention give good results and avoid long-term complications such as chronic pain, weakness, and subacromial impingement of shoulder.
