Abstract | Introduction: The study aimed to determine the gender differences in 3-dimensional (3D) acetabular morphology in
Chinese adults, which would provide useful information on the aetiology of hip arthritis and the design of total hip
arthroplasty prostheses.
Methods: Volumetric computed tomographic data on 112 subjects without hip symptoms were used; Mimics and
SolidWorks softwares were utilised for 3D construction. The acetabular parameters, including acetabular abduction angle
(ABA), anteversion angle (AVA), acetabular width (AcW), and acetabular depth (AcD) were measured. The acetabular
index of depth to width (AcD/AcW) was calculated by depth / width × 100.
Results: Among the 66 female subjects, the mean (± standard deviation) age was 32.1 ± 2.8 years, and the mean ABA, AVA,
AcW, and AcD were 42.5 ± 3.5 degrees, 19.8 ± 2.3 degrees, 51.6 ± 4.9 mm, and 17.8 ± 2.1 mm, respectively. For the 46 males,
the mean age was 30.5 ± 3.9 years, and the mean ABA, AVA, AcW, and AcD were 38.3 ± 2.3 degrees, 17.1 ± 2.6 degrees, 57.1
± 3.8 mm, and 17.9 ± 2.5 mm, respectively. Compared with male subjects, significant increases in ABA and AVA (p < 0.05),
as well as significant decreases in AcW (p < 0.05) and AcD/AcW (p < 0.05) were noted in women.
Discussion and Conclusion: The complex geometry of the concave acetabulum benefits from 3D visualisation and
quantification. We provided a set of reference ranges for normal 3D acetabular morphology in the Chinese population. The
ABA and AVA were significantly larger in women than in men. |
