The Circumferential Evaluation of Subtrochanteric Femoral Cortical Thickness and Medullary Canal Diameter according to Age and Gender

Abstract

Aim: The aim of this study was to evaluate changes in the subtrochanteric femoral cortical thickness and the medullary canal diameter according to age and gender. Materials and Methods: In total, 840 radiographs of 420 hips of patients aged between 10 and 80 (210 males and 210 females) were included in this study. The two groups (males and females) were divided into three subgroups according to age, forming six groups in total. Results: Males showed significant differences in the thickness of the lateral, anterior, and posterior cortex with age, but no age-related differences were noted in the diameters of the mediolateral medullary canal and anteroposterior medullary canal. Females showed significant differences in the thickness of medial, lateral, and anterior cortex with age and significant age-related differences in the diameters of mediolateral medullary canal and anteroposterior medullary canal. Conclusion: The anterior, posterior, medial, and lateral cortex thicknesses of the femur and the anteroposterior and mediolateral widths of the medullary canal independently show different developmental characteristics according to age and gender. © 2018 Bentham Science Publishers.
