Introduction: The acetabulum is also home to the acetabular fossa, an attachment site for the ligamentum teres, a triangular, somewhat flattened band implanted by its apex into the antero-superior part of the fovea capitis femoris. The notch is converted into a foramen by the transverse acetabular ligament; through the foramen nutrient vessels and nerves enter the joint. MATERIALS AND METHODS: This is a prospective, descriptive, cross sectional and observational study conducted at Department of Anatomy and Radiology, Government Medical College, Ajamgrah and Department of Anatomy and Radiology, Index Medical College, Indore from January 2020 December 2022. Study group divided into 3 groups: Group A: 18-35 years, Group B: 36-55 years and Group C: 56- 75 years Result It is defined as the angle between the line connecting the lateral edge of the acetabular roof touching the lower iliac tip of acetabular surface and a line parallel to the pelvic tear drop. The angle between the centre line of both femoral heads and the line from centre towards the anterior margin of acetabulum. The angle between the centre line of both femoral heads and the line from centre towards the posterior margin of acetabulum. CONCLUSION: The depth studied on acetabulum in the present study showed statistically significant differences between males and females. Studies based on depth of acetabulum are relatively few in the literature, hence the findings of the present study can provide a guideline for further studies on acetabulum. Considering that total hip replacement is a common surgery performed now a day, awareness of the dimensions of the acetabulum is of immense importance to the orthopaedic surgeons.
