Key result
Total shoulder arthroplasty with glenoid alignment correction maintains centering in ~83% of posteriorly decentered shoulders.
Why the study?
Does surgical correction of glenoid alignment with soft tissue balancing during total shoulder arthroplasty improve humeral head centering in patients with primary osteoarthritis and posterior glenoid wear?
Population
77 patients with primary osteoarthritis and posterior glenoid wear, mean age 67.6 years.
Design
Cohort
Follow-up
mean 2 years (range, 1-7 years)

Does surgical correction of glenoid alignment with soft tissue balancing during total shoulder arthroplasty improve humeral head centering in patients with primary osteoarthritis and posterior glenoid wear?
Surgical correction of glenoid alignment with soft tissue balancing during total shoulder arthroplasty effectively maintains humeral head centering in patients with primary osteoarthritis and posterior glenoid wear.
Habermeyer et al. (2006) conducted a cohort in Primary osteoarthritis with posterior glenoid wear (n=77). Total shoulder arthroplasty with surgical correction of glenoid alignment was evaluated on Postoperative humeral head centering. Total shoulder arthroplasty with surgical correction of glenoid alignment maintained centered humeral heads in 83.3% of patients with preoperative posterior decentering at a mean 2-year follow-up.
