Abstract
Background: Anthropometeric study of the hip joint has important clinical implications. A through knowledge of hip joint anatomy is a prerequisite to understand its biomechanics. 
 Methods: It was a hospital based observational study conducted for the period of one year starting form 17th September 2015 to 16th September 2016. The study population included all patients in the age group of 18 years and above submitting to the department of Radiodiagnosis for either abdominal, lower spinal or non orthopaedic pathology of pelvic and hip region.
 Results: Mean of right acetabular in males is 16.90±4.330SD and mean of left acetabular anteversion angle in males is 16.5 0±4.20SD. Mean of right acetabular in females is 18.1 0±4.80SD and mean of left acetabular anteversion angle in females is 17.6 0±4.70SD
 Conclusion: There is significant side to side difference in acetabular abduction angle of male and female and abduction angle don’t change significantly with age. There is significant side to side difference in acetabular anteversion angle of male (p-value <0.05) and female and anteversion angle don’t change significantly with age. Anteversion angle found to be more in female as compared to male.
 Keywords: Hip bone, Acetabular angle, CT scan.
Highlights
It is well known that abduction and anteversion angles cannot reliably be evaluated with plain X-ray film, since pelvic tilt changes the measurement of angles of the native acetabulum by as much as 10◦, more over it is difficult to study 3-dimentional acetabulam on 2-dimentional radiograph completly

Summary
It is well known that abduction and anteversion angles cannot reliably be evaluated with plain X-ray film, since pelvic tilt changes the measurement of angles of the native acetabulum by as much as 10◦, more over it is difficult to study 3-dimentional acetabulam on 2-dimentional radiograph completly. 2. Acetabular anteversion and abduction angles are widely used in orthopaedic surgery practice. Acetabular anteversion and abduction angles are widely used in orthopaedic surgery practice Their definition and evaluation is often based on partial scientific evidence. Radiological inclinaton is defined as angle between the longitudinal axis and acetabular axis , when this is projected in coronal plane where as Radiological anteversion is the angle between acetabula plane and coronal plane.
