Protocole à fin de constitution d’un registre français des prothèses de hanche

Abstract

INTRODUCTION: Use of joint prostheses is growing widely, in particular in developed countries. The « Société Française de Chirurgie Orthopédique et Traumatologique » (SOFCOT) has submitted in 2007 to the «Commission Nationale Informatique et liberté» (CNIL) a project for creating a hip prostheses registry. More recently, the « Conseil National Professionnel de chirurgie Orthopédique et Traumatologique » (CNP-COT) developed a national implants and observatory registry on surgical orthopaedic and traumatologic practices and pathologies (RENACOT) aiming to assure traceability and materio-vigilance of hip implants used in France. The main objective of the study is to report the current state of surgical techniques, used implants and their evolutions in hip arthroplasty in France using retrospective data provided by a multicenter registry since 2006.MATERIAL ET METHODS: On the one hand, the research systematically lists the main characteristics of all implants used in hip arthroplasty; and on the other hand, these informations are correlated with epidemiologic, demographic data, CROMs and PROMs. The study group consists by all patients receiving a hip reconstruction either in traumatology (femoral neck fractures) or above all for degenerative diseases. The data are collected in 2 questionnaires. The link between primary and revision surgery of the same prosthesis is automatic through the patient social security N°, sex and operated side.RESULTS: Patient demographics provides the corresponding population epidemiologic information’s. Registered data are available through 3 modes: 1- In running time, the registry board members only can accede to all collected data by internet 2- A biennal report of the national hip replacement activity 3- Any particular request about a specific matter or implant DISCUSSION One of the major registry interests in case of revision is the possibility to assure an automatic link with the corresponding primary arthroplasty. This is only possible if the primary questionnaire is already implemented and if the correspondence between the primary arthroplasty and the same hip reoperation/revision can automatically be established from the moment where both questionnaires are correctly completed in the registry. The CNP, through the RENACOT spreading use, aims to extend such registry practice to all orthopaedic and traumatologic surgical fields.
