Introduction: The objective was to study the morphology of the acetabular margin and articular surface and to measure the various dimensions of the acetabulum in dry human hip bones. Material and Methods: A cross-sectional morphological and morphometric study was performed on 92 undamaged acetabulum of adult dry human hip bone of unknown age and gender. The shape of anterior margin of the acetabulum and shape of the anterior and posterior ends of the articular surface of the acetabulum were observed. Morphometry was done using a Vernier caliper of accuracy of 0.01 mm. Vertical diameter (VD), transverse diameter (TD), anteroposterior diameter (APD), internotch distance (ND), and depth of the acetabulum were measured. Surface area (SA) and volume (V) of the acetabulum were calculated by mathematical calculation of dome. Statistical analysis was done using SPSS software version 22.0 (IBM, SPSS statistics, UNICOM GLOBAL, California, United States). The Pearson's correlation test was used. Results: In the present study, the anterior acetabular ridge was curved in 45.7% (42), angulated in 26.17% (24), straight in 13% (12), and irregular in 13% (12) bones. The anterior end of the lunate articular surface was angulated, and the posterior end was lunate in shape in 45.7% (42), whereas in 54.3% (50), bone both the ends were lunate in shape. Morphometric values and mean ± standard deviation were as follows: 48.21 mm ± 3.31 mm (VD), 47.81 mm ± 3.37 mm (TD), 48.79 mm ± 4.08 mm (APD), 23.58 mm ± 2.77 mm (ND), 27.45 mm ± 3.02 mm (D), 4162.56 mm2 ± 755.58 (SA), and 36,563.65 mm3 ± 9408.67 (V). Discussion and Conclusion: The knowledge of these acetabular parameters is necessary for the creation of acetabular prosthesis and surgical procedures such as acetabular reconstruction in hip joint surgeries.
