case_images: Radiographic assessment of case 1. A: X-ray of the pelvis showing bilateral coxarthritis at the ankylosis stage. B: Control radiograph after the right prosthesis had been fitted. C: pelvis X-ray after completion of the left prosthesis, complicated intraoperatively by a peri-prosthetic fracture treated by steel wire cerclage. D: Immediate postoperative hip X-ray, profile view.

case_images: Also, given the position of the nerve on the greater trochanter, we were obliged to cut the pelvic trochanters almost flush with the bone, which led to considerable bleeding that we were unable to control, resulting in a state of hemorrhagic shock stabilized by drugs and transfusion (Figures 3-5).
case_images: Intraoperative image of case 3. The image is showing an unusual location of the greater sciatic nerve glued to the posterior aspect of the greater trochanter.. 1: Posterior aspect of the greater trochanter. 2: Greater sciatic nerve.

case_images: Radiographic findings in the case 3 patient with an abnormal location of the sciatic nerve. A: Front pelvis X-ray showing bilateral ankylosis of both hips secondary to ankylosing spondylitis. B: Postoperative control pelvis radiograph after the first prosthesis on the right, which passed without complication. C: Postoperative control pelvis radiograph after the second prosthesis on the left, during which this anatomical peculiarity was revealed.
