Analysis of Proximal Femoral Morphologic Parameters in Turkish Adult Population by Computed Tomography

Abstract Aim: The study was performed to understand the differences in the morphometric properties of the proximal femur between age, sex and right-left side in the Turkish population. Materials and Methods: Morphometric measurements were made on CT images of 404 people (210 men, 194 women). People were four grouped into 10 year age ranges. We measured femoral head diameter, femoral neck diameter, femoral head length, femoral neck length, inter trochanteric length, hip axis length, femoral axis length, acetabular depth, inclination angle, lateral central edge angle, Alsberg Angle, anterior central edge angle, posterior central edge angle, acetabular anteversion angle, Sharp Angle, acetabular abduction angle. We calculated femoral head coverage ratio and acetabular depth width index. Results: All length, depth, diameter measurements, inclination angle and acetabular abduction angle were found greater in males than in females. Posterior center edge angle, acetabular anteversion angle and Sharp angle were found greater in women than in men. Femoral head diameter was measured smaller in the 20-29 age group compared to other age groups. It was determined the femoral head coverage ratio increased with age. Sharp angle decreased significantly between the ages of 20-29 and 50-59. depth width index were found larger on the left side. Conclusion: Knowing the morphometric values of the proximal femur revealed in this study may contribute to the procedures to be applied to the proximal femur and hip region and may also increase the reliability of operative situations.
