A Conservatively Managed Posterior Sternoclavicular Joint Dislocation in a Young Adult

Abstract

Posterior sternoclavicular joint dislocation (SCJ) is rare especially in the young patients and can be complicated by serious complications related to the proximity of the joint to mediastinal structures. We describe the case of a previously healthy 22-year-old male who presented with a right shoulder injury. Clinically, the patient only complained of pain in the right shoulder and right hemithorax with no functional deficit or signs of neurovascular or cardiorespiratory impairment. Following imaging, the diagnosis of a closed posterior SCJ dislocation without associated mediastinal injury was confirmed. Conservative management was initially planned because of the lack of complications and the patient's stable clinical condition. This is noteworthy with regards to that it is an unusual non-severe presentment of diagnosis of posterior SCJ dislocation. Currently, there is minimal evidence in the literature of this type of injury, but it should be taken into account as it may lead to fatal complications. Early imaging and multidisciplinary evaluation are necessary for the selection of appropriate management. The patient achieved complete recovery following conservative treatment, emphasizing that non-operative management can be effective in select cases with stable clinical presentation.
