Abstract

The Register for Orthopaedic Prosthetic Implantation (RIPO) has been prospectively collecting data on hip prostheses performed in all the orthopaedic units in the region Emilia-Romagna since January 2000. The register aims to determine the characteristics of patients, evaluate the effectiveness of prostheses, and allow internal audit. Adherence to the register is compulsory (93% capture). By 31 December 2006 the register contained data on 35,041 primary total hip arthroplasty (THA), 14,613 hemiarthoplasties, and 5,878 revisions. All prosthetic components are registered on an individual basis. Survival analysis is done following the Kaplan Meier method. Cumulative survival rate at 7 years is 96.8% (95% CI: 96.4–97.1%) for THA and 97.6% (97.0–98.3%) for hemiarthroplasties. Multivariate analysis verified that survival of the THA is affected by pathology, where the worst conditions are rheumatoid arthritis, femoral neck fracture, and sequelae of coxitis or Paget’s disease. Results are comparable to other major registers of Northern Europe and Australia.

Résumé

Le Registre de Prothèses Orthopédiques (RIPO) a récupéré, progressivement les données des prothèses de hanches, réalisées dans des services d’orthopédie de la région Emilie – Romagne depuis le 1er janvier 2000. Le but de ce registre est de déterminer les caractéristiques des patients et d’évaluer les bénéfices des prothèses et permettre un audit interne. L’adhésion à ce registre n’est pas obligatoire mais volontaire, 93% d’adhésions. Au 31 décembre 2006, ce registre comprenait 35.041 prothèses totales de hanche primaires, 14.613 hémiarthroplasties et 5.878 révisions. Les courbes de survie ont été réalisées selon la méthode de Kaplan Meier. La courbe de survie cumulative à 7 ans était 96,8% (95% intervalle de confiance: 96.4–97.1%) pour les prothèses totales, 97.6% (97.0–98.3%) pour les hémiarthroplasties. Les courbes de survie sont affectées par la pathologie des patients. Les conditions les plus défavorables sont l’arthrite rhumatoïde, les fractures du col, les séquelles de coxite ou de maladie de Paget. En conclusion, les résultats de ce registre sont comparables aux autres registres du Nord de l’Europe et de l’Australie.
