Cemented stems have given good results with no difference in outcome when comparing taper slip and composite beam designs in short-term randomised trials. We aimed to ascertain differences in outcome between the different cemented design philosophies using a large-scale registry analysis. A retrospective cohort study of National Joint Registry of England and Wales (NJREW) was conducted. The study population included all primary total hip operations performed in the UK from 1 April 2003 to 31 September 2012. All cemented stems were identified and categorised as taper slip (polished) or composite beam (non-polished).Introduction
