The acetabulum is a cup shaped portion of the hip bone, that articulates to the femoral head of the femur bone. The acetabulum and the femur bone together forms the bony structure of the hip joint. The main function of acetabulum is that it allows us to walk, run and move freely. Fractures are one of the most common problems that are seen in acetabulum. The excess growth of acetabulum causes the femoral head and the acetabular socket to pinch the labrum of acetabulum resulting in excess pain and decreased range of mobility. The treatments of acetabular fractures can be done through non surgical and surgical methods. The aim of the study is to do the anatomical observation and morphometric study of acetabulum in the south indian population. In the present study, 40 dry hip bones were collected from Anatomy Department of Saveetha Dental college and Sri Ramachandra Medical college, out of which 20 hip bones were of males and 20 hip bones were of females which were pre recorded in the department. These hip bones were collected to analyse two parameters, diameter of acetabulum and width of the notch of the acetabulum. The data that was obtained were analysed and standard deviation values were obtained for both the parameters. These values were plotted in the form of bar graphs.This study concludes that the diameter and the notch of acetabulum was found to be greater in males than females.
