A comparative analysis of a central metaphyseal humeral fixation stemless shoulder arthroplasty to an anatomic shoulder arthroplasty in a national registry cohort.

Background: This study aimed to determine the revision outcome between a centrally fixed stemless anatomic design and other total anatomic shoulder replacements using data from a large national arthroplasty registry.

Methods: The study period was from December 2011 to December 2022 and included three cohorts; primary Affinis stemless anatomic (AFS), all other primary total stemless anatomic (sTSA) and primary total stemmed anatomic shoulder arthroplasty (aTSA). The endpoint was all-cause revision using cumulative percent revision (CPR).

Student and clinician perceptions of medical student mistreatment: a cross-sectional vignette survey.

Objectives: The mistreatment of medical students remains pervasive in medical education. Understanding the extent to which clinicians and students recognise mistreatment can assist in creating targeted interventions that reduce mistreatment. The objective of this study was to use clinical vignettes to assess perceptions of medical student mistreatment among medical students and clinical faculty at an Australian university.
