What range of flexion is typical for the hip joint?

The typical range of hip joint flexion is indeed between 110 to 120 degrees. This range is important as it reflects the functional capacity of the hip joint during activities such as walking, running, and climbing stairs. A full and healthy flexion allows individuals to perform movements that require lifting the thigh towards the abdomen, which is essential in many daily activities and sports.

In physical assessments and rehabilitation settings, understanding this range helps to evaluate joint function and mobility. It can also guide interventions to restore or improve flexion capability in cases where limitations are present due to injury or conditions affecting the hip.

The other options suggest ranges that fall outside of what is functionally expected of a healthy hip joint. For instance, values like 30-50 degrees or 10-15 degrees would indicate significantly limited hip flexion, which could be a sign of dysfunction or pathology. The range of 50-70 degrees is also comparatively low for an optimal healthy hip joint flexion. Hence, 110-120 degrees represents the standard for typical hip joint flexion.
