Abstract:
Surgical treatment options for proximal humeral fractures include hemiarthroplasty (HA), reverse shoulder arthroplasty (RSA), and open reduction and internal fixation (ORIF). The objectives of this study were to analyze the trends in surgical treatment of proximal humeral fractures across a decade and to compare complications, reoperation rates, and readmission rates between ORIF and RSA.
Methods:
The PearlDiver MUExtr Database was used to identify patients with proximal humeral fractures who were treated with ORIF, HA, or RSA between 2010 and 2019 and analyze yearly trends. Complications, revision procedures, demographic characteristics, comorbidities, and emergency room visits and hospital readmissions within 90 days of the surgical procedure were compared between ORIF and RSA cohorts for patients who had at least 2-year follow-up data.
Results:
In this study, 384,158 patients with proximal humeral fractures were identified in the 10-year period between 2010 and 2019. There was a significant increase in the frequency of RSA and a decrease in the frequency of ORIF and HA over time (p < 0.0001). Compared with patients who underwent ORIF or HA, patients who underwent RSA were more likely to be older (p < 0.0001), to be female, and to have a higher Charlson Comorbidity Index. Patients who underwent ORIF had higher complication rates (23.03% compared with 18.62%; p < 0.0001) and higher reoperation rates (20.3% compared with 10.3%; p < 0.0001) than patients who underwent RSA. Patients who underwent RSA had higher emergency room visit rates (20.0% compared with 16.7%; p < 0.001) and hospital readmission rates (12.9% compared with 7.3%; p < 0.0001) within 90 days of the surgical procedure compared with patients who underwent ORIF.
Conclusions:
There has been an increasing trend in RSA utilization for the surgical treatment of proximal humeral fractures, along with a decreasing trend in HA and ORIF, over time. Patients who underwent ORIF for a proximal humeral fracture had higher complication and reoperation rates compared with patients who underwent RSA. Patients who underwent RSA had higher emergency room visit and hospital readmission rates within 90 days of the surgical procedure compared with patients who underwent ORIF, which may be attributable to the RSA cohort being older and having more comorbidities.

Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
