Age-related decrease in supratrochanteric torsion and increase in infratrochanteric torsion in healthy pediatric femurs: an MRI study

This study included 282 (164 males and 118 females) patients aged 1–18 years. The axial MRI of patients with benign tumoral lesions of the femur was retrospectively reviewed. The measurements were performed through axial images of contralateral healthy femurs. Femoral anteversion, STT, and ITT were measured twice by two orthopedic surgeons. The Pearson correlation coefficient was used to test for the correlation of age between STT, ITT, and femoral anteversion in children. All femoral anteversion, STT, and ITT measurements showed excellent intraobserver and interobserver reliability (P
