Modified Distalization Shoulder Angle and Lateralization Shoulder Angle show weakly correlation with clinical outcomes following reverse shoulder arthroplasty.

Introduction: The focus in reverse shoulder arthroplasty (RSA) has been on the lateralization and distalization of prosthesis positioning, influenced by implant design and surgical technique. There's no consensus on the optimal amount of lateralization and distalization or the best radiographic parameters for evaluating placement. This study examines the correlation and the predictive value between previously described modified distalization shoulder angle (DSA) and lateralization shoulder angle (LSA) with postoperative outcomes, which aim to differentiate the contributions of the humeral and glenoid components in the global distalization and lateralization of the RSA.

Revision shoulder arthroplasty and proximal humeral bone loss: a comprehensive review and proposal of a new algorithm of management.

With the rising prevalence of shoulder arthroplasty, the incidence of revision shoulder arthroplasty is also increasing. The complexity of these revision procedures poses significant challenges, with bone loss being a critical factor impacting treatment outcomes. Addressing substantial humeral bone defects is crucial for ensuring implant stability and functionality.

Bone Density Changes at the Origin of the Deltoid Muscle following Reverse Shoulder Arthroplasty.

Reverse total shoulder arthroplasty (RSA) significantly impacts deltoid length, tension, and structure. Studies have extensively investigated various modifications in deltoid characteristics, such as perfusion, elasticity, caliber, histological changes, and strength post-RSA. However, to date, there is a notable absence of research evaluating changes in bone mineral density (BMD) at the deltoid muscle origin after the RSA procedure.

Narrative identity among people with disabilities in the United States during the Covid-19 pandemic: The interdependent self.

This study examines narrative identity among a large, diverse sample of people with disabilities (PWDs) in the United States during the "second wave" of the Covid-19 pandemic (October-December 2020). The study relied on abductive analyses, combining a purely inductive phase of inquiry followed by two rounds of investigation that filtered inductive insights through three theoretical lenses: social-ecological theory, the theory of narrative identity, and perspectives from the interdisciplinary field of disability studies. The central result was the identification of a particular configuration of self, one that was demonstrably interdependent with both immediate interpersonal contexts and with broader cultural contexts.
