For olecranon bursitis, how is the diagnosis best established?

• A. Imaging is mandatory
• B. Ultrasound-guided aspiration is required
• C. Blood tests are necessary
• D. The diagnosis can be made from history and the physical examination, with no additional workup

Answer: (D)

Olecranon bursitis is typically a clinical diagnosis. A careful history and exam usually identify it: a boggy swelling over the back of the elbow that develops after repetitive elbow pressure or a minor injury, with or without mild discomfort. In uncomplicated cases, imaging and blood tests aren’t required because they won’t change management. Look for signs that would prompt drainage and fluid analysis for infection (septic bursitis): fever or systemic symptoms, warmth or marked redness around the swelling, severe focal tenderness, or drainage from the bursa. If infection is suspected, aspirating the bursa and sending fluid for cell count, Gram stain, and culture is appropriate and guides treatment. Imaging is not routinely needed to diagnose straightforward olecranon bursitis and is reserved for cases with diagnostic uncertainty or to evaluate alternative or complicating issues (for example, persistent swelling despite treatment, concern for fracture, or underlying pathology).
