Gerdy's tubercle is a landmark on which bone?

• A. Fibula
• B. Tibia
• C. Femur
• D. Humerus

Answer: (B)

Gerdy's tubercle marks the insertion of the iliotibial band on the tibia, located on the lateral aspect of the proximal tibia just below the knee. The tibia is the weight-bearing bone of the lower leg, and the iliotibial band runs along the outer thigh to attach there, helping stabilize the knee during movement. This makes the tibia the correct bone for this landmark. The fibula sits laterally but does not host this insertion, and the humerus and femur have other distinct landmarks rather than Gerdy’s tubercle.
