The hip bone consists of three–part ilium, ischium, and pubis. After ossification it’s become a single large right & left hip bone its irregular, centrally constricted bone that is called hip bone, understanding to this bone slightly typical for undergraduate Student. The study focused on Auricular surface of hip bone. The posterior border is irregularly curved and descends from the posterior superior iliac spine.This is a unique study it has been done in dried adult human bones of unknown sex. The data will be useful for anatomists, surgical treatment to the fracture of hip bones, arthroplasty, anthropologists and Forensic medicine department. The material of the present study consists of 154 dry human hip bone of Unknown sex. The bones measurement taken from different medical colleges. Teerthanker Mahaveer Medical college & Research Centre, Moradabad (U.P)., Shri Ram Murti Smarak Institute of Medical Sciences, Bareilly, (U.P) and KGMU, Lucknow (U.P). Parameter measured height & width of the hip bone. The study has been done with Metric methods.The mean ± S.D value of width and Height of auricular surface were 20.12 ± 3.75mm & 35.93 ± 5.44mm. Positive and significant correlation was found between the width and height of the auricular surface of the bone (r = 0.28). In this study 5% significance level and various levels of significance are considered. The Correlation between morphometrical parameters were investigated using z–test which have, p<0.0001 was significant level.This study was also undertaken to add new dimensions of hip bone. This is a new research work. Although it may be of significance for future further studies in this medical fields. Morphological study on adult hip bone is useful for anatomists, anthropologists, experts of Forensic medicine, and orthopedics for performing surgical procedures in this area. A radiological study may be added for further accuracy.
