Comparative Analysis of Short and Mid-Term Results of Primary Total Hip Replacement by Serial Cemented and Uncemented Fixation Implants

Abstract

Analysis of short-term (5 - 8 years) and mid-term (10 - 14 years) results of primary total hip replacement using cemented and uncemented fixation implants of foreign (Zimmer) and home (Endoservice) serial production. The study was based on the results of 2620 surgical interventions (2911 operations, out of them 1512 - with ESI, 1399 - with Zimmer implants) performed in two independent clinics. Revision intervention due to aseptic loosening of implant components was required in 62 (ESI) and 66 (Zimmer) cases and the terms of that complication development were practically the same. In 5 to 8 years after operation excellent, good and satisfactory results (70 - 100 points by Harris) were observed in 95.2% of patients operated on using ESI implants and in 94.8% of patients - with Zimmer implants. In 10 - 14 years the indices made up 89.2 and 88.2%, respectively. Thus, the results of different implants application were comparable
