Predicting revision risk for aseptic loosening of femoral components in total hip arthroplasty in individual patients--a finite element study.
Advances in surgical procedure, prosthesis design, and biomaterials performance have considerably increased the longevity of total joint replacements. Preoperative planning is another step in joint replacement that may have the potential to improve clinical outcome for the individual patient, but has remained relatively consistent for a long time. One means of advancing this aspect of joint rep...
متن کاملEarly aseptic loosening of uncemented femoral components in primary total hip replacement. A review based on the Norwegian Arthroplasty Register.
The Norwegian Arthroplasty Register recorded 24,408 primary total hip replacements from 1987 to 1993; 2907 of them (13%) were performed with uncemented femoral components. We have compared the results of eight different designs, each used in more than 100 patients. Survivorship of the components was estimated by the Kaplan-Meier method using revision for aseptic loosening of the femoral compone...
متن کاملRestoration of bone stock after aseptic loosening of a distal post-resections femoral prosthesis.
Background. The aseptic loosening of the stem is a frequent complication of post-resection endoprosthesis. Material and methods. Twenty-one patients were operated for primary neoplasm of the distal femoral epiphysis. In 3 cases (14.3%) loosening of the endoprosthesis stem appeared 4 to 8 years after the resection-reconstruction procedure. In all cases the endoprosthesis was reinserted with reco...
متن کاملRadiological features predictive of aseptic loosening in cemented Charnley femoral stems.
The radiological features of the cement mantle around total hip replacements (THRs) have been used to assess aseptic loosening. In this case-control study we investigated the risk of failure of THR as predictable by a range of such features using data from patients recruited to the Trent Regional Arthroplasty Study (TRAS). An independent radiological assessment was undertaken on Charnley THRs w...
متن کاملA Hydroxyapatite Coated Collar Reduces Aseptic Loosening of Cemented Distal Femoral Massive Bone Tumour Prostheses
Background: Aseptic loosening of massive bone tumour implants remains one of the major causes of prosthesis failure. Question: The hypothesis of this study was that an osteointegrated hydroxyapatite (HA) coated collar would reduce the incidence of aseptic loosening around the cemented intramedullary stem in distal femoral bone tumour prostheses. Methods: Twenty-two patients were pair matched in...
