Ten-Year Survivorship and Risk of Periprosthetic Fracture of a Cementless Tapered Stem

This article is a retrospective review of a consecutive series of 401 primary total hip arthroplasties with the use of cementless, ream and broach Synergy stem (Smith & Nephew, Memphis, TN, USA) with minimal 10-year follow-up. We report an overall 10-year survivorship of 99.6% with a total of 15 fractures during the study period. Six of these fractures occurred intraoperatively. This is the largest series to our knowledge reporting greater than 10-year follow-up. This stem has excellent survivorship with overall low risk of periprosthetic fracture.
