What should you know about sternoclavicular osteomyelitis?

The sternoclavicular joint connects the inner end of the collarbone to the breastbone. Infection may affect the joint, nearby bone, or surrounding soft tissues. Pain, tenderness, swelling, warmth, and reduced shoulder movement can occur, sometimes with fever or feeling unwell.

A clinician may examine the chest and shoulder, order blood tests and imaging, and collect a sample when possible to identify the organism. The appearance of the skin may not show the full extent of infection, so deeper pain or persistent symptoms should be assessed.

Treatment is planned by a medical team and commonly involves antimicrobial medicine chosen for the suspected or confirmed infection. The route and duration depend on the examination, test results, response, and whether the joint or surrounding tissues are involved.

Rest the affected shoulder as advised, but do not immobilise it indefinitely without guidance. Keep scheduled reviews and report changes in pain, swelling, temperature, or arm movement. If infected tissue does not settle or bone damage is substantial, a surgical opinion may be needed; bone grafting is one possible reconstructive topic, not an automatic treatment.

Seek urgent medical care for fever with increasing pain or swelling near the collarbone, spreading redness, drainage, shortness of breath, confusion, faintness, or marked weakness. These symptoms can indicate infection is progressing or affecting nearby structures.

Ask which tests are needed, whether a culture was obtained, how long treatment may continue, and which symptoms mean you should return urgently. Discuss shoulder movement, wound care if a procedure is performed, and how recovery will be monitored.
