A STUDY ON MORPHOMETRIC MEASUREMENT OF VOLUME OF ACETABULUM

Background: Hip joint represents an unique functional unit and has complex biomechanical construction. In today’s era where total hip replacement surgeries have made their way it has become imperative for the anatomists to know the variations in acetabular dimensions. Reconstruction of acetabulum in patients with significant acetabular bone deficiency remains a challenge. Hence the present study was carried out with the aim to study the morphometric measurement of volume of acetabulum in both the sexes. Materials and Methods: Material of the study consisted of 110 human hip bones (60 males and 50 females). Volume of Acetabulum (VA) was measured on these hip bones on both the sides. Statistical analysis was done using SPSS (Statistical Package for the Social Sciences) version 11 and Microsoft Excel 2007. Results: The mean volume of acetabulum in male was 23.13 ml and female was 17.88 ml. The mean volume of acetabulum on right side was 20.55 ml and left side was 20.91 ml. Volume of the acetabulum was greater in males as compared to females and the differences were statistically significant. Volume was greater on the left side as compared to the right side but the difference was statistically non significant. Discussion: Analysing the differences on human acetabulum is helpful in understanding not only morphological but also medicolegal aspects. Conclusion: Volume of the acetabulum was greater in males as compared to females.
