The use of reverse shoulder arthroplasty is becoming increasingly popular for the treatment
of complex three-and four-part proximal humerus fractures in the elderly compared with the …

Purpose The impacts of humeral offset and stem design after reverse shoulder arthroplasty
(RSA) have not been well-studied, particularly with regard to newer stems which have a …

The reverse shoulder arthroplasty (RSA) has revolutionized reconstructive shoulder surgery.
Secondary to promising clinical results, the reverse shoulder prosthesis has generated a …

Background Our study purpose was to determine the optimal glenoid and humeral reverse
shoulder arthroplasty (RSA) component design and position in osteoarthritic shoulders with …

Background Little is known about the effects of glenosphere diameter on shoulder joint
loads. The purpose of this biomechanical study was to investigate the effects of glenosphere …

Purpose Our purpose was to evaluate the influence of metallic lateralisation of the centre of
rotation (COR) in reverse shoulder arthroplasty (RSA) on the incidence of scapular notching …

Purpose: This study quantifies the ability of humeral retroversion, glenoid tilt, bone graft, and
varying prosthesis design parameters to restore anatomic muscle length and deltoid …

Background Reverse shoulder arthroplasty (RSA) increases the moment arm of the deltoid;
however, there is limited knowledge on the accompanying changes in muscle architecture …

Purpose To determine how different combinations of humeral stem and glenosphere
designs for reverse shoulder arthroplasty (RSA) influence range of motion (ROM) and …

Aims Scapular notching is a frequently observed radiographic phenomenon in reverse
shoulder arthroplasty (RSA), signifying impingement of components. The purposes of this …
