Baseball pitchers are most commonly affected by which bursitis?

• A. Trochanteric Bursitis
• B. Infrapatellar Bursitis
• C. Subacromial Bursitis
• D. Olecranon Bursitis

Answer: (C)

Overhead throwing puts repetitive stress on the shoulder, especially in the space between the rotator cuff tendons and the acromion where the subacromial bursa sits. With repeated throwing motions, this bursa becomes irritated and inflamed, leading to pain and impingement during an overhead throw. That makes subacromial bursitis the most common bursitis seen in baseball pitchers, since their sport directly involves long periods of arm elevation and rapid throwing mechanics.

Hip bursitis (trochanteric) is more typical in runners or those with hip abductor weakness. Knee bursitis (infrapatellar) relates to kneeling or jumping activities. Elbow (olecranon) bursitis occurs with direct trauma or sustained pressure on the elbow, not as a typical throwing-related injury.
