Sex Determination through Acetabular Standards on Western up Population Using CT scan

Objective: Acetabular morphology differs by geographic location. This study reveals an analysis of the Northern Indian population’s native acetabulum using coronal, sagittal, and axial metrics based on CT. Hypothesis: Sex estimation in north Indians is accurate with acetabular measures. Material Method: NCCT pelvis of 132 patients (73 female and 59 male) were done in the Department of Radiological and Imaging Techniques, Teerthanker Mahaveer University, Moradabad. Acetabular diameter (AD), Transverse acetabular diameter (TAD), Cotylopubic length (CP length), Acetabulum-pubis index (A-P index), and Length from ischial tuberosity to acetabulum rim were measured. The study comprised fully ossified human hip bones free of morphological and pathological flaws. A-P index was calculated by using formula: AD × 100 / CP length Results: The study included 59 males and 73 females, with a mean age of 41.1±15.3 years (20–80 years). In this study, females had a significantly higher CP length (p<0.001). AD and AP index were significantly larger in males when compared to females.
