Fünf- bis Zehn-Jahresergebnisse für den Oberflächenersatz des Hüftgelenks

Abstract

Hip resurfacing is a common method for therapy of coxarthritis and is currently under discussion. The aim of this study was to analyze hip resurfacing follow-up studies with more than 5 years follow-up time. A total of 17 studies which matched the inclusion criteria were analyzed. The survival rate after 5-6 years was 96.3%, after 7-8 years 93.8% and after 9-10 years 90%. Young men with primary coxarthritis and surgery by an experienced surgeon showed the best results. The main causes for revision were aseptic loosening with 34.4% and fracture of the proximal femur with 31.9%. Dislocation as a cause for revision was rare and occurred in 2.8% of all cases. Hip resurfacing showed worse results than conventional hip arthroplasty. The risk for complications was high especially for women, with small prostheses and in patients with suboptimal positioning of the prosthesis.

Femoral neck prostheses: A systematic analysis of the literature

“…7 Considering the demographic change a further increase in primary THA is predictable. 8,9 Estimations regarding THA in New Zealand indicate an increase of implantation rate up to 84.0% till 2026. 10 Estimations for Australia indicate an increase of 66% concerning the incidence rate (interventions per 100,000 inhabitants) of primary THA from 2013 to 2046.…”

“…In general, aseptic loosening is the most common cause for revision in THA. 9,12 Main risk factors for aseptic loosening are male sex, high activity level and patient’s age. 8…”
