The neck of the femur is angled anteriorly from the femoral body by how many degrees?

5° to 10°
15° to 20°
30° to 40°
40° to 60°

The correct answer is: 15° to 20°

The neck of the femur is angled anteriorly from the femoral body by approximately 15° to 20°. This anatomical feature is important because the angle helps to allow for a greater range of motion at the hip joint. A more acute angle facilitates movements like flexion and extension, contributing to the overall biomechanics of lower limb motion. Understanding this angle is crucial for radiologic technologists and healthcare professionals, as it aids in accurately interpreting imaging studies and understanding potential pathologies or variations in individual anatomy. Keeping in mind that the neck of the femur plays a major role in the proper function of the hip joint is essential for both diagnosis and treatment in orthopedic practice. The other options significantly overshoot the typical angular range observed in healthy adult anatomy, making them less applicable in this context.
