Endosteal femoral bone loss after hip rearthroplasty

A controlled computed tomography study of 12 patients

Abstract

The cortical bone area of the middle femur was investigated with computed tomography in 12 patients after hip rearthroplasty due to aseptic prosthetic loosening. The patients had undergone their original arthroplasty because of unilateral arthrosis 11 years before these measurements. Both legs were scanned, and the reoperated side was compared with the healthy side. A control group was chosen of 13 patients with unilateral hip arthroplasty because of unilateral arthrosis, but without subsequent rearthroplasty. In the patients who had undergone rearthroplasty, there was an 11% loss in endosteal bone area of the middle femur compared with the contralateral side. In the control group (non-reoperated patients), only a loss of 6% was found compared with the contralateral side. The periosteal bone area of the reoperated femur and the non-reoperated femur showed no significant change compared with the corresponding healthy side. The larger endosteal resorption noted among patients in the rearthroplasty group could be ascribed to the primary prosthetic failure and could also contribute to further aseptic prosthetic loosening.
