Abstract
Purpose
This study employed CT multi-planar reconstruction and cinematic rendering techniques to measure anatomical parameters of the hip joint. It aimed to compare the differences in hip joint anatomical parameters among adults of different age groups and analyze their correlations with baseline data such as height, weight, and BMI.
Methods
A total of 156 cases, comprising 312 hips, were included and divided into six groups based on 10-year age intervals. The following parameters of both hip joints were measured: acetabular anteversion angle, center-edge angle, acetabular coverage rate, acetabular depth, neck shaft angle, femoral offset distance, center-edge angle, anterior and posterior acetabular sector angles, and acetabular anteversion angle. Data were analysed and processed using SPSS statistical software.
Results
When comparing the different age groups, the values of Acetabular coverage, Acetabular depth and other hip parameters were lower in the young adult group than in the older group, but the Sharp angle was greater than in the older group. There was no statistically significant correlation between the innovative and traditional measures of Acetabular coverage and Acetabular depth (r = 0.76, 0.95, P < 0.01). Sharp angle also showed correlation with body mass index and other hip parameter indices.
Conclusion
There are significant differences in hip joint anatomical parameters among different genders and age groups, and significant correlations exist between various anatomical parameters. There is a close relationship between some anatomical parameters and the mechanism of hip arthroplasty, hip dislocation and femoroacetabular impingement, which plays a crucial role in clinical management.
