What should you know about infected olecranon bursitis?

The olecranon bursa cushions the bony point at the back of the elbow. Repeated pressure, a small break in the skin, or spread from a nearby infection can allow germs into this sac. The elbow may become tender, hot, red, and visibly swollen. Bending the elbow can be uncomfortable, although the joint itself may still move.

A clinician may look for a skin wound, check the elbow and nearby tissues, and use blood tests or imaging when necessary. Joint Aspiration can remove fluid from the swollen area for testing; this helps distinguish infection from non-infectious inflammation.

Keep pressure off the elbow and protect any skin break with a clean dressing. Do not squeeze the swelling, puncture it yourself, or share antibiotics. Treatment may include prescribed antibiotics, drainage, and review of the fluid findings. Anti-Inflammatory Medication may help selected non-infectious inflammation, but it does not replace assessment when infection is suspected.

If infection persists, returns, or leaves a troublesome bursa, Bursa Removal may be considered by an orthopaedic team. The choice depends on examination findings, response to treatment, and the condition of the overlying skin.

Seek same-day medical care for a rapidly enlarging swelling, spreading redness, pus, increasing pain, fever, chills, or difficulty moving the elbow. Go to emergency care if you feel faint, confused, severely weak, or develop breathing difficulty. A red streak moving up the arm or a new wound near the swelling also needs urgent review because infection can extend into surrounding tissue.

Ask whether the bursa or elbow joint is involved, whether fluid should be sampled, which treatment is appropriate, and how the dressing should be managed. Ask when you should return, how to reduce pressure on the elbow, and what symptoms would mean the infection is spreading.
