Femoral Neck-shaft Angle in Sohag Population

Study Overview
=================
Brief Summary
-----------------
The femur or thigh bone is the strongest and longest bone of the body and about 45 cm long in an average man that means approximately one fourth of the height of individual. It has upper end, lower end and a cylindrical shaft. Upper end consists of head, neck. The neck is about 5 cm long, connects the head to the shaft and is directed upward, medially and slightly forward and making an angle about 125 with shaft but the angle is wider in children. The neck-shaft angle (NSA ) is defined as the angle formed by the neck axis and long axis of the shaft of femur.The knowledge of the neck shaft angle is valuable in the diagnosis and treatment of fracture of upper end of femur. The aim of the study is : to evaluate the normal values of femoral neck-shaft angle to detect factors that may affect this angle as age, and sex, in Egyptian adults from Sohag.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| To measure femoral neck-shaft angle ( NSA) . | We will use Computed Tomography (CT) in determination and measurement of femoral neck shaft angle ( NSA) and its variation relating to age and sex. Neck-shaft angle will be measured using Image Works by noting angle between two intersection lines representing proximal femoral shaft axis and the femoral neck axis. Normal neck-shaft angle varies from 115°-140° (mean of 126°). Normal range neck shaft angle is 121°-138°in male. Normal range neck shaft angle is 119°-137°in female. | 16 weeks following the startpoint of the study |
