Within this study, 10 arthroplasty surgeons planned 20 arthroplasties (10 glenohumeral osteoarthritis and 10 rotator cuff tear arthropathy) with three prosthesis configurations.
Comparing 3D Computer-Assisted Planning With and Without Patient-Specific Instrumentation
Computer navigation has been shown to be most effective while robotics, which shows promise, is relatively new to the field.5,6 Computer navigation has over six years of clinical use, offering improved precision with minimal additional cost or operative time.7
Optimizing distalization and lateralization in reverse arthroplasty for cuff arthropathy
Regarding the distalization of the implant, it was shown that there were effectively no upper limits of DSA on outcome, meaning that the more distal the better, at least in this study.
Shoulder Arthroplasty Failures: What Role Does Malposition Play?
While technological advances such as PSI, navigation, and AR/MR have been shown to improve glenoid component position, this article highlights the need to further improve component position technologies for both the glenoid and humerus.
Pectoralis Minor Tenotomy in Shoulder Arthroplasty: A Novel Therapeutic Approach
While further studies are certainly imperative, in the absence of any observed short-term complications, pectoralis minor tenotomy appears to be a safe and potentially effective mitigation strategy for addressing distal neuropathy and improving scapulohumeral rhythm in reverse shoulder arthroplasty procedures.
Review of Acromial and Scapular Fractures After Reverse Shoulder Arthroplasty: Inlay vs. Onlay Component Designs
Study of 3,018 reverse shoulders finds no strong link between inlay or onlay designs and risk of acromial or scapular fractures.
A Review of Convertible-Platform Shoulder Arthroplasty
This review discusses implant design, common failure modes, and considerations for primary and revision shoulder surgery.
Does 3D shoulder planning give us any information?
Reverse shoulder arthroplasty: 3D planning for ROM prediction. Study on humeral stem design and patient factors impacting surgical outcomes.
Computer Navigation in Shoulder Arthroplasty
A Review of the Article by Emilie Cheung and Anna Ramakrishnan in Seminars in Arthroplasty by Peter Chalmers, MD.
Review of “Reverse shoulder arthroplasty for patients with cuff tear arthropathy: do clinical outcomes differ by inlay vs. onlay design?”
Peer review of study comparing inlay vs. onlay humeral designs in RTSA outcomes, showing similar function and complications.
