The six deep external rotator muscles of the hip (piriformis (PI), quadratus femoris (QF), obturator internus (OI), obturator externus (OE), superior gemellus (SG), and inferior gemellus (IG)) play a role in both hip stabilization and rotation and are damaged and relocated during total hip arthroplasty surgery.
