Aims Existing literature indicates that inferiorly inclined glenoid baseplates following reverse
total shoulder arthroplasty (RSA) produce better outcomes compared to superiorly inclined …

Background Optimal glenosphere positioning in a lateralized reverse shoulder arthroplasty
(RSA) to maximize functional outcomes has yet to be clearly defined. Center of rotation …

Background The anterosuperior (AS) approach for reverse total shoulder arthroplasty
(RTSA) has been reported as a risk factor for baseplate malposition because of potential …

Background There is concern that excessive glenoid component retroversion leads to
altered biomechanics and baseplate failure in reverse shoulder arthroplasty (RSA) …

Background Reverse total shoulder arthroplasty (rTSA) exhibits high rates of success and
low complication rates. rTSA has undergone numerous design adaptations over recent …

Introduction While lateralization of the glenohumeral center of rotation during reverse
shoulder arthroplasty (RSA) has benefits of maintaining tension on the remaining rotator cuff …

Introduction The complications of the conventional medialized design for reverse total
shoulder arthroplasty (RSA) are increased scapular notching, and decreased external …

Background This study aims to compare the range of motion (ROM) of reverse shoulder
arthroplasty lateralised by bony increased offset (BIO-RSA) using a standard 38-mm (mm) …

Background In a previous biomechanical study, eccentric glenospheres with more inferior
position of the center of rotation were shown to improve range of motion and reduce the …

Background Lateralization in reverse total shoulder arthroplasty (RTSA) has been used to
theoretically offer the potential benefits of reduced scapular notching rates and improved …
