We examined the influence of fixation method on revision rate and mortality. Methods: We analyzed approximately 25,000 hemiarthroplasty cases from the AOA National Joint Replacement Registry. Deaths at 1 day, 1 week, 1 month, and 1 year were compared for all patients and among subgroups based on implant type. Results: Patients treated with cemented monoblock hemiarthroplasty had a 1.7-times higher day-1 mortality compared to uncemented monoblock components (p < 0.001). This finding was reversed by 1 week, 1 month, and 1 year after surgery (p < 0.001). Modular hemiarthroplasties did not reveal a difference in mortality between fixation methods at any time point. Interpretation: This study shows lower (or similar) overall mortality with cemented hemiarthroplasty of the hip.enOpen Access - This article is distributed under the terms of the Creative Commons Attribution Noncommercial License which permits any noncommercial use, distribution, and reproduction in any medium, provided the source is credited.HumansHip FracturesPostoperative ComplicationsProsthesis FailureArthroplasty, Replacement, HipFracture Fixation, InternalReoperationCementationRegistriesHip ProsthesisAgedAged, 80 and overAustraliaFemaleMaleJournal article002010916310.3109/17453674.2011.5842080002910600000042-s2.0-7995781685629514Pratt, N.
