Hip bone is a unique articulation of arthrology having three different bone like Ilium, Ischium & Pubis. In which ischium has great knowledge to give reliable information to Obstetrician, gynecological, Human Ergonomics & Biomechanics Studies. The study has worked on 154 dry hip bone from different medical colleges in Uttar Pradesh in India. Height, width & Shape of ischial tuberosity were observed significantly, which is use for radiological as well as Anatomical studies. The mean±S.D value of width and height of Ischial tuberosity were 45.34 Ischial Tuberosity 4.75mm, 25.11 ± 3.46mm & different shapes of ischial tuberosity were observed like pear (94.81%), Quadrangular (4.54%) and Triangular (0.65%) shapes. Morphological study on adult hip bone ischial tuberosity diameter & Shapes are useful for Anatomists, Anthropologists, Experts in Forensic medicine, and Orthopedics for performing surgical procedures in this area. A radiological study may be added for further accuracy
