Femoral bone remodeling: clinical experience with cemented and cementless total hip arthroplasty.
A radiographic study of femoral bone tissue remodeling around hip arthroplasty was carried out simultaneously in two series totalling 224 cementless and 77 cemented prostheses. Remodeling was analyzed by detailed visual evaluation of the radiographic assessment. The results show that the phenomenon of bone remodeling is still evolving more than 5 years after surgery. Bone demineralization of the proximal femur is more evident in cementless prostheses than in those stabilized with acrylic cement (24% vs. 12%). The preoperative state of mineralization significantly influences bone remodeling.
