Current literature supports the use of total hip replacement (THR) for the treatment of displaced intra-capsular proximal femoral fractures (DIPFF). Case series of patients receiving this treatment show dislocation rates higher than that of patients who have THR to treat osteoarthritis. Large diameter THR have mechanical advantages in terms of dislocation and their role in PFF has yet to be assessed. To assess the role of large-diameter total hip replacements on the rate of dislocation when used to treat displaced intra-capsular proximal femoral fractures. Design: Single surgeon, case series Setting: Level I trauma centre Inclusion criteria: Displaced intra-capsular proximal femoral fracture (Garden III & IV). Independently mobile pre-operatively for distances greater than a mile, with no more than 1 stick as a mobility aid. Abbreviated mental test score of 9/10 or greater Exclusion criteria: Patient under 60 Pathological fractures Additional fractures of the femur Outcomes Mortality Morbidity (Including dislocation) Oxford Hip Score SF12 Patients/Participants: Retrospective study to assess patients who presented between May 2006 and December 2008 and met the requirements had a CPTÒ (Zimmer) cemented femoral stem, using 3rd generation cementation techniques, and large diameter Duronò (Zimmer) head and cup (uncemented) inserted as a primary procedure via a modified Hardinge technique. Follow up was via routine clinic appointments, letter to GP and phone conversation with patient.Introduction
