Results of primary total hip replacement with first generation Bousquet dual mobility socket with more than twenty five years follow up. About a series of two hundred and twelve hips

Abstract

The aim of our study was to evaluate long-term survival and dislocation rate of this concept. It was a retrospective study, on 212 hips using a Bousquet dual mobility Novae® tripodal socket (SERF). Mean follow-up was 25.3 years (95 to 372 months). Mean age at the time of the surgery was 53 years. Pre-operative mean Harris and PMA scores were respectively 54.14 and 11.2. Their respective last follow-up counterparts were 83.6 and 16.9; 25 year follow-up cup survival rate was 90.6%. No dislocation occurred, 45 hips were revised (including 17 cup aseptic loosenings, ten intra prosthetic dislocations, nine liner changes, seven stem failures, two sepsis). Dual mobility socket global long term survival rate was comparable to similar cemented or uncemented series. The absence of dislocations proved the interest of dual mobility concept in hip stability. Implant improvements might widen DM socket indication.
