BACKGROUND: Lateral offset center of rotation (COR) reduces the incidence of scapular
notching and potentially increases external rotation range of motion (ROM) after reverse …

Background Complication rates after reverse total shoulder arthroplasty (RTSA) have, in
previous series, been reported to be high. The purpose of this study was to describe the …

This study analyzes the muscle moment arms of three different reverse shoulder design
philosophies using a previously published method. Digital bone models of the shoulder …

Purpose This study compares the radiographic and functional outcomes of uncemented and
cemented humeral fixation in reverse total shoulder arthroplasty (RTSA). Methods A …

BACKGROUND: Following shoulder arthroplasty, any well-planned rehabilitation program
should include muscle strengthening. However, it is not always clear how different external …

Background Modern semiconstrained reverse shoulder arthroplasty (RSA) has shown a
great improvement in function and range of motion (ROM) in different etiologies, including …

Background Revision shoulder arthroplasty can be complicated by osseous and soft tissue
deficiencies. Proximal humeral bone loss can result in diminished implant stability and …

Background Fracture reverse shoulder arthroplasty (fRSA) in geriatric, complex dislocated
proximal humerus fractures is becoming the standard treatment next to conservative …

Background Numerous studies have examined the biomechanics of isolated variables in
reverse total shoulder arthroplasty. This study directly compared the composite performance …
