Bone remodeling around cementless hip implants.
Bone remodeling results from the adaptation of bone to the stresses that act upon it. The insertion of an endoprosthesis into a femur changes the stress distribution within the femur, causing the bone to remodel. In this paper, we show how radiographic bone remodeling changes can be used to determine implant fixation and how bone remodeling changes can be quantitated by using dual-energy x-ray absorptiometry analysis as well as computer-assisted videodensitometry.
