Humans and platyrrhines share a pattern of articular variance

open access: yesThe Anatomical Record, EarlyView.
Abstract Previous work has identified a pattern of articular shape variation in modern human limb joints, in which convex joint surfaces exhibit constrained variance relative to their more variable concave conarticulars. This pattern is notable given that joint morphogenesis is influenced by local biomechanical environments, which vary substantially ...

Systemic Hormonal Contraceptive Use Is Associated With Greater Odds of Rotator Cuff Tears, Shoulder Instability, Dislocation, and Other Shoulder Pathologies: A Propensity Matched Epidemiological Study

open access: yesArthroscopy, EarlyView.
Purpose To evaluate whether systemic estrogen‐only, progestin‐only, or combined hormonal contraceptives (HCs) are associated with increased risk of shoulder pathologies in reproductive‐age females. Methods A retrospective cohort study of female patients presenting to clinic from 2013 to 2020 and aged 13‐50 with 5 years of follow‐up was conducted using ...
