The femur is the longest and strongest bone in the human body. It is about 45 cm in length in an average man. The femoral neck-shaft angle (NSA) is very important in the diagnosis and treatment of many pathological conditions relating to the femur and hip joint. Our study aims to evaluate the values of femoral NSA and detect the relationship between this angle and age in the Sohag population. 3-Patients & Methods CT scans of 300 patients (40. 90 years, range of 18 – 60 years; 150 females). CT scans were reformatted to three-dimensional pelvic models (3D) simulating standardized radiographic views of anteroposterior roentgenograms of the pelvis in the anterior pelvic plane (APP). NSA values were 129.45° (range 116.1°–146.7°; SD 4.88°) for patients aged from 18y to 39y & 129.48° (range 115.7°–145.9°; SD 5.25°) for patients aged from 40y to 60y. There was no statistically significant difference regarding NSA & age as p-value = .785 (p-value > .05). Correlation analysis revealed no significant relationship between NSA and age.
