Posterior sternoclavicular joint dislocation.

Area of Science:

• Orthopedic Surgery
• Trauma Care
• Radiology

Background:

• Posterior sternoclavicular (SC) joint dislocations are uncommon injuries.
• These dislocations can lead to life-threatening complications like hemorrhage or tracheal compromise.
• Misdiagnosis is possible, with initial presentations sometimes mistaken for other injuries.

Purpose of the Study:

• To describe a case of posterior SC joint dislocation in a young athlete.
• To highlight the diagnostic role of CT scans in identifying posterior SC joint dislocations.
• To emphasize the importance of recognizing clinical signs and employing prompt reduction techniques.

Main Methods:

• Case report of a 21-year-old college football player with a shoulder injury.
• Initial diagnosis based on physical examination and plain radiographs.
• Further evaluation with CT scan to confirm the diagnosis.

Main Results:

• Initial diagnosis was an apophyseal injury of the SC joint.
• Increased pain prompted further investigation.
• CT scan revealed a posterior SC joint dislocation.

Conclusions:

• Posterior SC joint dislocations require prompt diagnosis and management.
• CT imaging is essential for accurate identification of posterior SC joint dislocations.
• Knowledge of diagnostic signs and reduction techniques can mitigate serious complications.
