BACKGROUND: The knowledge of the angle of inclination is a valuable aid in the diagnosis and treatment of the fractures of upper end of femur. Neck-shaft angle is defined as the angle formed by the neck axis and long axis of the shaft of femur. Normal neck-shaft angle varies from 120˚-140˚.  A decrease in the normal neck-shaft angle is known as coxavera while if the angle is more than 140° it is known as coxa-valga. Pelvic radiograms were taken with 15-30 degrees of internal rotation of the hips in the supine position. 15 inch×12 inch films were used in this study. the present study we also divide the total population in different age groups as A (20-40 years), B (41-60years), C (61-80years) and compare the N.S.A related with each group. According the age group A, B, C the mean neck shaft angle of the right side was more than left side but not statistically significant. In present study the mean neck shaft angle in the total population of the right side was (130.22˚) and on left side was (129.81˚). In present study there was Low –ve correlation (-0.0156) between right side mean Neck shaft angle with Age and Low +ve correlation (0.026.)
