Hartford et al.^1* conducted a retrospective study of 798 primary total hip replacements by one surgeon performed using non-collared dual tapered femoral stems. The first group included 457 THA procedures implanted with the Avenir Hip System with a hybrid rasp-impaction broaching and the second included 341 THA implanted with another non-collared stem using impaction broaching¹.

Intra-operative and 90-day post-operative fractures were identified in each group. Bivariate tests and multivariate regression analysis were used to compare the two groups.

Conclusion from the study was that the use of a hybrid rasp-impaction broach compared with impaction broach led to a reduced incidence of periprosthetic fractures when using a dual tapered stem through the direct anterior approach.

*Study does not specifically analyse Avenir Complete System

Avenir Complete System is our cementless hip stem designed on the proven heritage² of Avenir Hip System to facilitate a precise, balanced, and intuitive femoral preparation and aimed to offer an accurate and precise stem seating thanks to its hybrid rasp-impaction broaching technique.
