Which condition involves inflammation of a bursa?

• A. Fracture
• B. Bursitis
• C. Kyphosis
• D. Osteoarthritis

Answer: (B)

Bursitis occurs when a bursa, the small fluid-filled sac that cushions joints and reduces friction between moving tissues, becomes inflamed. This inflammation leads to pain, tenderness, swelling, and sometimes warmth around the affected joint, with movement that aggravates the symptoms being especially uncomfortable. The bursa’s job is to provide a smooth gliding surface for tendons and bones, so when it’s inflamed, the cushioning is compromised and irritation increases.

This condition is distinct from a fracture, which is a break in bone; kyphosis, which is an abnormal curvature of the spine; and osteoarthritis, which is degeneration of joint cartilage. So inflammation of a bursa specifically identifies bursitis.
