Oba M, et al. - Researchers assessed the influence of femoral neck resection on the mechanical strength of the proximal femur in actual surgery. As per the results, an association of the bone resection depth measured at the head-neck junction and transcervical reference plane with fracture risk after osteochondroplasty was observed. On the contrary, at more proximal areas, bone resection did not have a significant effect on the postoperative femur model strength in FEA. They did not note an association of the total volume of resected bone with postoperative changes in femur model strength.
