BACKGROUND Aseptic implant loosening and periprosthetic bone loss are major problems after total hip arthroplasty (THA). We present an in vivo method of computed tomography (CT) assisted osteodensitometry after THA that differentiates between cortical and cancellous bone density (BD) and area around the femoral component. METHOD Cortical and cancellous(More)
Periprosthetic bone loss after total hip arthroplasty is common. It can be progressive and, in the extreme, may compromise survival of the prosthesis. With quantitative computed tomography, we determined the pattern of periacetabular cortical and cancellous bone density changes after press-fit cup implantation with alumina liners. We recruited 24 patients(More)
AIMS We prospectively analyzed the cancellous and cortical periprosthetic femoral bone reaction after implantation of a cementless total hip arthroplasty with computertomography assisted osteodensitometry after a mean of 1 and 6 years. MATERIALS AND METHODS Twenty-one patients (Ø age at implantation: 52 years) with osteoarthrits of the hip joint received(More)
