Anthropometry of the proximal femur and femoral head in children/adolescents using three-dimensional computed tomography-based measurements.

Purpose: Defining normal anthropometric ranges of proximal femur and femoral head for each age group in children/adolescents is a necessity when differentiating normal anatomical variants from pathological deformities. Aim of this study is to define a set of normal anthropometric parameters based on 3D-CT measurements in normal asymptomatic children/adolescents and analyse the variations arising depending on age, side, and/or gender.

Methods: Morphology of the proximal femur was retrospectively assessed in 170 hips (85 children, < 15 years).
