BackgroundThere is a paucity of data comparing periprosthetic hip fracture (PPHFx) outcomes and resource utilization to native fractures. Many surgeons consider periprosthetic hip fractures to be more severe injuries than native fractures. The aim of this systematic review is to characterize the outcomes of PPHFx and assess their severity relative to native hip fractures (NHFx).MethodsA Preferred Reporting Items for Systematic Reviews and Meta-Analysis systematic review was conducted using Medline, Biosis, and Cinahl. Primary outcomes were time to surgery, length of stay (LOS), cost of management, disposition, complication rates, readmission rates, and mortality.Results14 articles (13,489 patients) from 2010 to 2018 were included in the study. Study quality was generally low. Patient follow-up ranged from 1 month to 3.2 years. LOS ranged from 5.2 to 38 days. US cost of management was best estimated at $53,669 ± 19,817. Discharge to skilled nursing facilities ranged from 64.5 to 74.5%. Time to surgery ranged from 1.9 to 5.7 days. Readmission rates ranged from 12 to 32%. Per Clavien-Dindo classification, 33.9% suffered minor complications; 14.3% suffered major complications. 1 month and 1 year mortality ranged from 2.9% to 10% and 9.7% to 45%, respectively.ConclusionTime to surgery and LOS were longer for PPHFx relative to NHFx. Complications' rates were higher for PPHFx compared to NHFx. There is no evidence for differences in LOS, cost, discharge, readmission rates, or mortality between PPHFx and NHFx. These results may serve as a baseline in future evaluation of PPHFx management.© 2023. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.
