Fig. 1From: Comparison of postoperative effectiveness of less invasive short external rotator sparing approach versus standard posterior approach for total hip arthroplastySurgical approaches in surgical methods. Virtual images of a standard surgery: cutting off the piriformis, obturator internus, gemellus superior and inferior, and quadratus femoris. Virtual images of b corrective surgery: transection of the quadratus femoris, inferior gemellus, and distal obturator internus; longitudinal splitting of the obturator internus; and conserving the piriformis tendon, superior gemellus, and upper part of the obturator internus. Real images of c external rotator sparing approach in corrective surgery. Real images of d after repairing in corrective surgeryBack to article page
