Complications in Osteonecrosis Patients After Shoulder Arthroplasty: A Propensity-Matched Cohort Study.

ABSTRACT:

Background

Total shoulder arthroplasty (TSA) is an effective treatment for advanced osteonecrosis (ON) of the humeral head, a condition involving vascular disruption and bone necrosis. However, systemic comorbidities in ON patients may impact postoperative outcomes.

Purposes

We sought to evaluate health care utilization, systemic complications, and implant-related outcomes in TSA patients with and without ON.

Methods

Using the TriNetX research database, we identified patients who underwent TSA between December 9, 2002, and December 9, 2022. Two cohorts were created: The TSA + ON cohort included patients with any ON diagnosis of the humerus within 1 year leading to their TSA, and the TSA-only cohort excluded patients with ON of the humerus within the same timeframe.
