Sexual Dimorphism in Morphometry of the Acetabulum in Adult Bangladeshi People

Abstract

Context: Morphometry of acetabulum bears immense clinical, surgical, and medicolegal significance. It helps clinicians to diagnose and manage hip dysplasia and hip osteoarthritis. Radiological Morphometric parameters of the acetabulum are essential to orthopaedic surgeons for planning before acetabulum surgery and selection of appropriate size acetabular components during total hip arthroplasty. The present study was designed to establish data on different morphometric parameters of the acetabulum in the adult Bangladeshi population and to determine differences in these parameters between males and females.

Materials and methods: The study was conducted in the Department of Anatomy, Sir Salimullah Medical College, Dhaka from July 2020 to June 2021 on the anteroposterior radiographs of the pelvis of 70 adult Bangladeshi people age ranging from 25-45 years. Acetabular width and acetabular depth were measured unilaterally from the left side on the radiographs with MB ruler software. Then acetabular quotient was calculated. Comparison of the parameters between adult Bangladeshi males and females was done by unpaired student’s t-test.

Results: The mean acetabular width of male and female were 66.69 ± 3.49 mm and 60.19 ± 4.20 mm respectively; the mean acetabular depth of male and female were 20.47 ± 2.67 mm and 19.15 ± 2.92 mm respectively and the acetabular quotient of male and female were 305.09 ± 31.59 and 313.97 ± 31.84 respectively.

Conclusion: In the present study mean acetabular width was significantly higher in males while mean acetabular quotient was higher in females and the difference was significant.
