Summary
Origins
- Upper part of the ischial tuberosity
Insertions
- Medial surface of the greater trochanter via the tendon of the obturator internus
Actions
- Laterally rotates the hip
- Stabilizes the femoral head in the acetabulum
The inferior gemellus forms part of the deep lateral rotator stack beneath the gluteus maximus. It bridges the ischial tuberosity to the medial 📍 greater trochanter, sharing a common tendon with the obturator internus to swing the femur outward and steady the hip.
