Abstract: Aim: To determine the average acetabular antiversion angle in south Indian population, for ideal acetabular cup position in Total Hip Arthroplasty.
Background: Abnormal acetabular anteversion of the hip, has been from many years the etiogenesis of early hip wear and tear leading to osteoarthritis [1].
In this era the demand for total hip replacements has increased worldwide and in India as well. The acetabular anteversion angle plays a very important role in terms of longevity of the implant and cup positioning. Since studies on acetabular anteversion are very few compared to western and Asian studies hence, the purpose of this study is to find out the acetabular anteversion angle for south Indian population.
Materials and Methods: A retrospective study of 250 CT scans of hips where collected from 2017 to 2020 and the mean acetabular anteversion angle was measured which was compared with Asian and western population.
Results: The average acetabular anteversion angle is 20.9±3.19 there was no statically significant difference between male and female population, as with the side, left and right side (p=0.02). There was a significant 2 to 3 degree increase in acetabular antiversion compared to US, European and Asian studies.
Conclusion: The average acetabular anteversion angle 20.9 ±3.19 was significantly higher when compared to the western population due to the habitual cross legged sitting and squatting since childhood, hence this should be taken into consideration when designing and positioning acetabular cups during total hip arthroplasty.
