The normal range for hip medial rotation is up to how many degrees?

• A. 0-30°
• B. 0-60°
• C. 0-45°
• D. 0-15°

Answer: (C)

Internal rotation of the hip (medial rotation) is measured with the hip flexed so the joint’s soft tissues are tested in a position where rotation is most evident. In adults, the typical end range for hip internal rotation is about 40 to 45 degrees when the thigh is flexed to around 90 degrees. That makes 0 to 45 degrees the standard, normal range to expect. The other options either understate the end range (0-30, 0-15) or exceed the usual maximum seen in normal hips (0-60), so 0-45 degrees best fits common clinical findings.
