A. 76 year old female. Antero-posterior right hip X-ray. We can observe osteolysis and debonding around femoral stem of right hip. B. Immediate postoperative radiography. Conversion of standard to modular, distal fixation stems. We kept acetabular component because it was well fixed. C) Measure of the distance between the shoulder of the stem and the caudal edge of the lesser trochanter → 57,85 mm. D) 26 months later, you can see the distance decreases to 54,56 mm.
