90-day mortality after primary shoulder arthroplasty is generally low, but risk is significantly influenced by baseline comorbidities, ASA class, and underlying tumor diagnosis.

Resumen

90-day mortality following shoulder arthroplasty was low. An underlying diagnosis of tumor, higher comorbidity and higher ASA class were risk factors for higher 90-day mortality, while higher BMI was protective. Pre-operative comorbidity management may impact 90-day mortality following shoulder arthroplasty. A higher unadjusted mortality in patients undergoing TSA versus HHR may indicate the underlying differences in patients undergoing these procedures.
