Hydroxyapatite-coated total hip arthroplasty: The impact on survival and thigh pain
Journal Title: Αρχεία Ελληνικής Ιατρικής - Year 2008, Vol 25, Issue 6
Abstract
OBJECTIVE The purpose of this study was to evaluate the long term clinical outcome of primary total hip arthroplasty using an uncemented, hydroxyapatite-coated implant. METHOD A consecutive series of 164 patients (176 hips), who underwent total hip arthroplasty with the Furlong fully-hydroxyapatite coated implant was followed for a mean of 12.8 years (range 11-14 years). Clinical and radiological examinations were performed. X-ray evaluation of the femoral side of the hip was performed using the Gruen zones and of the acetabular side using the DeLee and Charnley zones. Engh's radiological score was employed to assess fixation and stability of the stem. The clinical result was evaluated by the Harris hip score. RESULTS The mean Harris hip score preoperatively was 46 and postoperatively 85, as recorded at the last follow up. The mean Engh score was 23. No hip had been revised for aseptic loosening of the femoral component at the time of final follow-up. Thigh pain incidence was very low (1.21%). The survival analysis showed excellent results (95.8% at the end point). CONCLUSIONS The clinical and radiological results with the Furlong hydroxyapatite coated implant are encouraging, rendering the implant reliable and safe for hip arthroplasties.
