Primary septic arthritis of the sterno-clavicular joint

Septic arthritis of the sternoclavicular joint (SCJ) is an uncommon form of arthritis generally occurring in immuno-compromised patients with contiguous or distant foci of infection and central venous catheters. Septic SCJ arthritis in previously healthy subjects is a very rare occurrence requiring a high index of suspicion for the diagnostic assessment. We report here one patient without predisposing factors presenting Staphylococcus aureus SCJ infection.
