Where is the most likely site of elbow bursitis in a patient with swelling near the elbow?

• A. Olecranon
• B. Capitellum
• C. Lateral epicondyle
• D. Medial epicondyle

Answer: (A)

The most likely site for elbow bursitis is the olecranon bursa, which sits directly over the olecranon at the posterior tip of the elbow. This superficial bursa is the one that commonly inflames with friction, trauma, prolonged pressure, or infection, producing a bump right over the back of the elbow. The other sites are bony landmarks or tendon attachment points rather than a superficial bursa. The capitellum is part of the distal humerus within the joint area, not a separate fluid-filled sac you’d expect to swell there. The lateral and medial epicondyles are prominent bony points where forearm tendons attach, so swelling in those areas would suggest epicondylitis or related tendon issues rather than bursitis. So, swelling near the elbow, especially at the posterior tip, points to inflammation of the olecranon bursa.
