Which anatomical feature is the rounded bony projection on the outer side of the ankle?

• A. Gout
• B. Malleolus
• C. Deep venous thrombosis
• D. Contracture

Answer: (B)

Recognize the rounded bony projection on the outer ankle as the lateral malleolus, the distal end of the fibula. This bony prominence forms part of the ankle mortise with the tibia and talus, giving lateral stability to the joint. The other terms aren’t bone landmarks: gout is a crystal-induced arthritis, deep venous thrombosis is a blood clot in a deep vein, and contracture is a shortening or tightening of soft tissues. So, the outer ankle projection is the lateral malleolus.
