Definition
Six short muscles produce lateral (outward) rotation of the hip.
Detail
There are 6 short muscles that function in lateral rotation of the hips:
- Piriformis
- Gemellus superior
- Gemellus inferior
- Obturator externus
- Obturator internus
- Quadratus femoris
(Hip lateral / outward rotation ROM is 45 to 60 degrees.)
Key facts
- 6 hip lateral rotators: piriformis, gemellus superior, gemellus inferior, obturator externus, obturator internus, quadratus femoris.
- Hip lateral (outward) rotation ROM: 45–60°.
Connections
- External Rotation — the movement they produce (lateral/outward rotation).
- Hip Joint Range of Motion — hip lateral rotation ROM.
- The Hip Complex — the hip structure.

External Rotation
Rotation with the axis of the bone turning away from the body (e.g., the humerus turned outward).The Hip Complex
The musculature spanning the hip — including the iliopsoas, tensor fasciae latae, sartorius and the iliotibial band — that flexes, extends, adducts, abducts, and rotates the hip.Hip Joint Range of Motion
Hip flexion 90° (knee extended) to 120° (up to 135°, knee flexed); hyperextension 10–30°; adduction 30°; abduction 45°; medial rotation 30–45°; lateral rotation 45–60°.
