What is the normal range for the angle of inclination of the femoral head?

The normal range for the angle of inclination of the femoral head is typically between 120 and 125 degrees. This angle refers to the relationship between the neck of the femur and the shaft of the femur. A well-defined angle within this range is essential for proper biomechanics of the hip joint, facilitating movement and weight-bearing activities. Maintaining this angle helps ensure efficient load distribution and joint stability during activities such as walking and running. An inclination outside this range can lead to altered mechanics and potentially contribute to conditions such as hip impingement or osteoarthritis.
