Traumatic Floating Clavicle: A Case Report and Updated Literature Review

Abstract

Traumatic floating clavicle or bipolar dislocation is a rare injury. Herein, we present a case of ipsilateral sternoclavicular and acromioclavicular joint dislocation after a motorcycle accident. The patient was a 43-year-old man who presented with right shoulder pain and limited range of motion. The radiograph revealed superior displacement of the acromioclavicular joint dislocation and suspected ipsilateral sternoclavicular joint dislocation and a CT scan confirmed injuries to both the medial and lateral ends of the clavicle. Due to the patient being active and young, we considered operative treatment. The sternoclavicular joint was stabilized with FiberTape® suture (Arthrex, Naples, FL), and the acromioclavicular joint with Dog Bone™ Button (Arthrex) and suture cerclage. At the one-year follow-up, the patient reported excellent outcomes without complications. We also summarize the literature on this particular injury, including its characteristics, surgical options, and treatment outcomes.
