    BackgroundReverse total shoulder arthroplasty (RTSA) has recently become an option for the treatment of proximal humerus fractures (PHFs) or as a salvage procedure after failure of another treatment. The purpose of this study was to compare primary RTSA with delayed RTSA in the treatment of displaced PHFs.Study Design & MethodsA retrospective cohort study was conducted on patients with PHFs who were treated between May 2013 and December 2021 with primary or delayed RTSA after failure of conservative treatment or osteosynthesis. Clinical data were withdrawn from our local computerized database. Complications, active range of motion, as well as the functional outcome were recorded at the end of the follow-up period. Differences between clinical outcomes were analyzed using a logistic regression analysis.ResultsA total of 70 individuals were included in this study (41 primary RTSA and 29 delayed RTSA). The mean of follow-up time was of 112 and 60 months, respectively. There were no differences between groups regarding fracture type according Neer Classification, ASA score or the presence of complications. Q-DASH and Oxford Shoulder scores were significantly better when patients underwent a primary RTSA (49.8 vs 31.4, p = 0.006 and 37.2 vs 27.5, p = 0.004 respectively). In addition, primary RTSA achieved more degrees of flexion and abduction than delayed RTSA (96.8 vs 72.9, p < 0.001 and 94.1 vs 69.3, p < 0.001 respectively).ConclusionPrimary RTSA for PHFs achieved better functional outcomes and a wider range of motion when compared with delayed RTSA. However, primary and delayed RTSA have similar complication and reintervention rates.Level Of Clinical Evidence3.Copyright © 2023 Elsevier Ltd. All rights reserved.
