Through Anatomical terms of motion
All muscles in the lateral rotator group originate from the hip bone and insert on to the upper extremity of the femur. The muscles are innervated by the sacral plexus (L4-S2), except the obturator externus muscle, which is innervated by the lumbar plexus.

Other lateral rotators
This group does not include all muscles which aid in lateral rotation of the hip joint: rather it is a collection of ones which are known for primarily performing this action. Other muscles that contribute to lateral rotation of the hip include:
- Gluteus maximus muscle (lower fibres)
- Gluteus medius muscle and gluteus minimus muscle when the hip is flexed (become medial rotators when hip is extended)
- Psoas major muscle
- Psoas minor muscle
- Sartorius muscle
