Shoulder arthroplasty improved function in patients with osteoarthritis due to instability. However, high complication rates in this patient group warrant further investigation into treatment outcomes.

Area of Science:

Orthopedic Surgery
Rheumatology

Background:

Shoulder instability can lead to advanced glenohumeral arthritis.
Arthritis secondary to instability and prior repair presents unique treatment challenges.

Purpose of the Study:

To describe clinical findings of glenohumeral arthritis from shoulder instability.
To evaluate clinical outcomes and complications of shoulder arthroplasty in these patients.

Main Methods:

Retrospective follow-up of 45 patients after shoulder arthroplasty for osteoarthritis.
Analysis of Constant scores and complication rates, comparing total shoulder replacement and hemiarthroplasty.

Main Results:

Significant improvement in weighted average Constant score (49.4 to 81.3).

Reverse Total Shoulder Arthroplasty

Reverse Total Shoulder Arthroplasty

Published on: July 5, 2011

High complication rate of 40% (18/45), with 20% (9/45) requiring revision surgery.

No significant difference in outcomes between total shoulder replacement and hemiarthroplasty.

Conclusions:

Shoulder arthroplasty effectively improves function in patients with osteoarthritis secondary to instability.
High complication rates in this cohort necessitate further research to identify causative factors.
