AIMS: Loss or absence of proximal femoral bone in revision @entity572 ( @entity572 ) remains a significant challenge. While the main indication for the use of proximal femoral replacements (PFRs) is in the treatment of @entity5 , they have a valuable role in revision @entity572 for loosening, @entity174 and @entity281 in @entity1 with @entity604 . Our aim was to determine the clinical outcomes, implant survivorship, and complications of PFRs used in revision @entity572 for indications other than malignancy. @entity1 AND METHODS: A retrospective review of 44 @entity1 who underwent revision @entity572 using a PFR between 2000 and 2013 was undertaken. Their mean age was 79 years (53 to 97); 31 (70%) were @entity1 . The @entity604 was classified as Paprosky IIIB or IV in all @entity1 . The mean follow-up was six years (2 to 12), at which time 22 @entity1 had died and five were lost to follow-up. RESULTS: The mean Harris Hip Score improved from 42.8 (25.9 to 82.9) pre-operatively to 68.5 (21.0 to 87.7) post-operatively (p = 0.0009). A total of two PFRs had been revised, one for @entity281 eight years post-operatively and one for aseptic loosening six years post-operatively. The Kaplan-Meier survivorship free of any revision or removal of an implant was 86% at five years and 66% years at ten years. A total of 12 @entity1 (27%) had a complication including six with a dislocation. CONCLUSION: PFRs provide a useful salvage option for @entity1 , particularly the elderly with massive proximal femoral @entity604 who require revision @entity572 , with significant clinical improvement. While the survivorship of the implant is good at five years, dislocation continues to be the most common complication. The judicious use of larger femoral heads, dual-mobility constructs, or constrained liners may help to minimise the risk of dislocation. Cite this article: Bone Joint J 2017;99- @entity69397 .
