Summary
This study reveals unique acetabular morphology in Vietnamese adults using CT scans. Findings highlight differences compared to global populations and a link between acetabular orientation and the transverse acetabular ligament.
Area of Science:
- Anatomy
- Radiology
- Orthopedics
Background:
- Acetabular anatomical parameters exhibit significant racial and geographical variations.
- Multislice Computed Tomography (CT) is an effective method for assessing acetabular morphology.
Purpose of the Study:
- To investigate the morphological characteristics of the acetabulum in Vietnamese adults.
- To establish baseline acetabular parameters for this specific population.
Main Methods:
- Sixty-three acetabula from 35 Vietnamese adult patients were analyzed using multislice CT with multiplanar reconstruction.
- Key morphometric parameters including acetabular inclination angle (AIA), acetabular anteversion angle (AAA), and acetabular diameter (ADi) were measured.
Main Results:
- Mean acetabular diameter was 50.22±3.56 mm, AIA was 40.27±5.09 mm, and AAA was 13.30±5.54 mm.
- Other measured parameters included AAS, SAA, TALA, TALI, AHO, ADe, and ADr, providing detailed morphometric data.
Conclusions:
- The study identified distinct acetabular morphological characteristics in Vietnamese adults compared to other global populations.
- A significant correlation was observed between acetabular orientation and the transverse acetabular ligament.
