Cementless Hydroxyapatite Coated Hip Prostheses
More than twenty years ago, hydroxyapatite (HA), calcium phosphate ceramics, was introduced as a coating for cementless hip prostheses. The choice of this ceramic is due to its composition being similar to organic apatite bone crystals. This ceramic is biocompatible, bioactive, and osteoconductive. These qualities facilitate the primary stability and osseointegration of implants. Our surgical e...
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...
متن کاملChanges in proximal femoral bone mineral density around a hydroxyapatite-coated hip joint arthroplasty.
OBJECTIVE To present the results of a prospective analysis of proximal femoral bone mineral density changes around a hydroxyapatite-coated total hip joint replacement. METHODS 14 patients with osteoarthritis of the hip were enrolled in the study and treated with an uncemented ABG prosthesis. Dual energy X-ray absorptiometry scanning was performed in 9 patients preoperatively, and at 3, 6, 12,...
متن کاملHydroxyapatite coated femoral stems in primary total hip arthroplasty: a meta-analysis.
We conducted meta-analysis of clinical studies of HA coated femoral stems in hip arthroplasty. After an exhaustive literature search, we abstracted relevant data on the outcomes of stem survival from aseptic loosening and Harris Hip scores. The risk ratios and mean differences with 95% confidence intervals (CI) are reported. 9 studies met our inclusion criteria for the analysis. The cumulative ...
متن کاملMedium-term results of cementless hydroxyapatite-coated primary total hip arthroplasty: a clinical and radiological review.
PURPOSE To evaluate the clinical and radiological outcomes following cementless primary hydroxyapatite-coated total hip arthroplasty. METHODS A retrospective study of 69 patients (82 hips) who underwent uncemented hydroxyapatite-coated Anatomic Benoist Girard total hip replacement between October 1991 and October 1995 at our institution was conducted. Patient records were reviewed. All patien...
