Does primary treatment of proximal humerus fractures show favourable functional outcomes over secondary treatment with reverse shoulder arthroplasty?

Background: This multicentre retrospective cohort study assessed whether functional outcomes after primary reverse shoulder arthroplasty (RSA) are favourable compared to secondary placement in elderly patients with displaced proximal humerus fractures (PHFs).

Methods: Fifty-three patients with primary and 32 with secondary RSA were included. Patient-reported outcome measures (PROMs) were assessed: Constant-Murley Score (CMS), Oxford Shoulder Score (OSS), Disabilities of the Arm, Shoulder and Hand (DASH) score, and Visual Analogue Scale (VAS).
