Hybrid glenoid component migration after total shoulder arthroplasty: a cohort study using radiostereometric analysis with 2 years' follow-up.

ABSTRACT:

Background and purpose

 Anatomic total shoulder arthroplasty (aTSA) is an effective treatment for glenohumeral osteoarthritis, but loosening of the glenoid component is a common cause for revision. Our primary aim was to analyze migration of a hybrid glenoid component in aTSA using marker-based radiostereometric analysis (RSA). Second, we aimed to compare early migration with later revision.

Methods

 Patients with primary glenohumeral osteoarthritis treated with a hybrid glenoid aTSA had tantalum markers inserted in the scapular bone and the glenoid component from 2017 to 2020. We used hybrid glenoid fixation techniques combining cementation with bone in-growth. Patients were followed with RSA radiographs for 24 months. Migration analyses included translation, rotation, and
