How normal is the enthesis by ultrasound in healthy subjects?

Abstract

Our results show a relatively high prevalence of US findings of "active" inflammation at the lower limb entheses in a group of healthy subjects, thus questioning the discriminant power of the OMERACT definitions for the diagnosis of "active" enthesitis. A combination of grey-scale and PD findings at a specific threshold to be defined could improve both the reliability and clinical usefulness of US.
