Long-Term Outcomes of RSA vs Nonoperative Care for Proximal Humerus Fractures .
This study has been identified as potentially high impact.
OE's AI-driven High Impact metric estimates the influence a paper is likely to have by integrating signals from both the journal in which it is published and the scientific content of the article itself.
Developed using state-of-the-art natural language processing, the OE High Impact model more accurately predicts a study's future citation performance than journal impact factor alone.
This enables earlier recognition of clinically meaningful research and helps readers focus on articles most likely to shape future practice.
Long-term outcomes of reverse shoulder arthroplasty versus nonoperative treatment for 3- or 4-part proximal humerus fractures in elderly patients: results from a prior randomized clinical trial.
J Shoulder Elbow Surg . 2025 Jun;34(6):1463-1470.Twenty-nine elderly patients (≥80 years) with displaced 3- or 4-part proximal humerus fractures were randomized to receive reverse shoulder arthroplasty (RSA) (n=17) or nonoperative treatment (n=12). The primary outcome was the Constant score. Secondary outcomes included Disabilities of the Arm, Shoulder and Hand (DASH) score, range of motion (ROM), pain (VAS), SF-12, EQ-5D, and radiographic findings. Outcomes were assessed at a mean follow-up of approximately 7.5 years. Overall, the results revealed that RSA achieved significantly higher Constant scores and better ROM, with no significant differences in quality-of-life measures or pain. Radiographically, all nonoperative cases healed in malposition without revision, whereas one RSA patient required revision for dislocation. These findings suggest that RSA offers superior long-term functional outcomes due to deterioration over time in the nonoperative group.
