Insertion of Gluteus Medius is on which landmark?

Insertion of Gluteus Medius is on which landmark?

• A. Medial surface of tibia
• B. Iliac crest of ilium
• C. Greater Trochanter
• D. Head of fibula

Answer: (C)

The key idea is where the gluteus medius tendon attaches to the femur to exert its action. This muscle extends from the outer surface of the ilium and inserts onto the lateral aspect of the greater trochanter of the femur. That insertion point—the greater trochanter—provides the leverage needed to abduct the thigh and help stabilize the pelvis during gait. The other landmarks aren’t insertion sites for this muscle: the medial surface of the tibia is where some knee/leg muscles attach, the iliac crest is a common origin for hip muscles but not the insertion for gluteus medius, and the head of the fibula serves as an insertion for muscles crossing the knee, not the gluteus medius.
