What is the normal range of hip lateral rotation?

• A. 0-25°
• B. 0-45°
• C. 0-15°
• D. 0-5°

Answer: (B)

External rotation of the hip is turning the thigh outward. In healthy adults, the end range of this motion is commonly around 40–60 degrees when measured with the knee bent, so a practical, commonly used normal bound in many exams is up to about 45 degrees. Measuring from neutral to that end point, 0–45 degrees captures the expected range for a typical assessment. Remember that the exact value can vary with age, gender, and how the measurement is performed (position, whether the knee is bent or straight), but 0–45 degrees is a standard, reasonable normal range for hip external rotation.
