Background: Trabecular metal is being increasingly used in primary total hip arthroplasty (THA). This study compared medium-term (< 15 years) outcomes of fiber mesh titanium and trabecular metal acetabular components.
Methods: This study included 6,563 patients who underwent primary THA with either fiber mesh titanium or trabecular metal-backed acetabular components.
Importance: The chronic neuronal burden of traumatic brain injury (TBI) is not fully characterized by routine imaging, limiting understanding of the role of neuronal substrates in adverse outcomes.
Objective: To determine whether tissues that appear healthy on routine imaging can be investigated for selective neuronal loss using [11C]flumazenil (FMZ) positron emission tomography (PET) and to examine whether this neuronal loss is associated with long-term outcomes.
Design, Setting, And Participants: In this cross-sectional study, data were collected prospectively from 2 centers (University of Cambridge in the UK and Weill Cornell Medicine in the US) between September 1, 2004, and May 31, 2021.
