Spontaneous sternoclavicular joint infections.

Spontaneous sternoclavicular (SC) joint infections are uncommon. Most cases of contained SC joint infections respond well to conservative treatment measures such as intravenous antibiotics and local drainage. However, some cases are more extensive, extending beyond the boundaries of the joint capsule, occasionally involving the anterior chest wall and mediastinum. We report our experience with 3 patients with spontaneous advanced SC joint infections. Radical surgical treatment seemed to provide the best control of this infection.
