Treatment of traumatic posterior sternoclavicular dislocations.

BACKGROUND Traumatic posterior sternoclavicular joint injuries are rare, but complications are common and include brachial plexus and vascular injury, esophageal rupture, and death. MATERIALS AND METHODS The records of 21 patients treated at our institution for a posterior sternoclavicular injury were reviewed. All patients underwent a trial of closed reduction, which was effective in 8 patients (group I). The remaining 13 patients were treated with open reduction and sternoclavicular joint reconstruction (group II). RESULTS Closed reduction was more likely to be successful (P < .05) in dislocations treated within 10 days of injury. Patients were evaluated by use of the University of California, Los Angeles rating scale. Overall, 18 of 21 patients were graded as good or excellent. Patients treated with either open or closed reduction as their definitive management compared favorably in terms of ratings for pain, strength, and motion. CONCLUSION Our experience suggests that closed reduction compares favorably with open reduction. Of patients treated, 38% required only closed reduction as their definitive treatment. In this series early closed reduction was successful and obviated the risks of surgery. Patients who in whom closed reduction failed obtained good results with operative treatment aimed at reconstruction of the costoclavicular ligaments.
