Introduction: The acetabulum, a component of the hip joint, plays a pivotal role in maintaining stability and facilitating a wide range of motion. Total hip arthroplasty is a widely accepted surgical intervention for patients suffering from various hip pathologies, including osteoarthritis, avascular necrosis, and fractures. The successful outcome of total hip arthroplasty is heavily reliant on accurate implant positioning within the acetabulum, as improper placement can lead to postoperative complications such as dislocation, impingement, and accelerated wear of the prosthetic components. Morphometric analysis of the acetabulum involves the quantitative assessment of its anatomical features, which can greatly influence the surgical approach, implant selection, and overall postoperative function of the hip joint. The aim of this study is to conduct a morphometric analysis of the acetabulum that belonged to the North Indian population and investigate its clinical significance in total hip arthroplasty. Materials and Methods: In this cross-sectional study, 110 adult dry hip bones (among which 55 belong to the right side and 55 belong to the left side) of unknown gender and age were studied in the Department of Anatomy, Jannayak Karpoori Thakur Medical College and Hospital, Madhepura, Bihar. We measured the diameter of the acetabulum, depth of the acetabulum, and width of the acetabular notch with the help of a digital vernier caliper which had a sensitivity of 0.01 mm and the least count observed was 0.01 mm. The obtained data is expressed in terms of Mean and standard deviation. A p-value less than 0.05 was considered significant in this study for analysis. The findings were tabulated and analyzed statistically by using the Graph Pad Prism version 9 software.  Results: We observed that the measurements of the diameter of the acetabulum on the right side were 47.94 ± 2.53 mm and on the left side was 46.87 ± 3.52 mm. The depth of the acetabulum on the right side was 25.05 ± 1.32 mm and on the left side was 26.16 ± 2.15 mm. While the width of the acetabular notch was 23.26 ± 3.55 mm on the right side and 23.97 ± 4.13 mm on the left side. In the present study, there were no significant differences found between the right and left side parameters of the acetabulum. Conclusion: The biomedical engineers will be able to create acceptable prostheses with the help of a complete understanding of the acetabulum's dimensions. The present study identified a number of acetabulum metrics that can be employed in total hip replacement to assess the acetabulum as part of preoperative planning.
