Final answer:
The Q-angle is the angle between the pelvis and the femur, usually between 10-15 degrees, with women typically having a wider angle due to their broader pelvis.
Step-by-step explanation:
The angle between the pelvis and the femur is known as the Q-angle, which stands for quadriceps angle. It is a measure of the amount of lateral deviation of the femur from the vertical line of the tibia. A normal Q-angle is typically between 10-15 degrees. Women generally have a larger Q-angle due to the wider pelvis, making them more susceptible to patellofemoral syndrome. The difference in the Q-angles is partly related to the anatomical adaptations for childbirth in females, resulting in a broader pelvis.
