The prevalence of, and risk factors for distal femoral cortical irregularity in the adolescent population.

Introduction: There is uncertainty around the pathogenesis and prevalence of distal femoral cortical irregularities (DFCI). We aimed to assess the prevalence of DFCI in a cohort of adolescents that underwent MRI and identify and assess associated risk factors.

Methods: A historical cohort study of adolescents (age 10 - <20 years) undergoing MRI scans was conducted.
