Hip motion in the horizontal plane is largely related to which pair of movements?

• A. Abduction/Adduction
• B. Internal/External Rotation
• C. Flexion/Extension Only
• D. Dorsiflexion/Plantarflexion

Answer: (B)

In the horizontal (transverse) plane, hip movement is about turning the thigh around a vertical axis. That motion is internal and external rotation of the femur relative to the pelvis. Abduction and adduction occur in the frontal plane (moving the leg away from or toward the midline). Flexion and extension occur in the sagittal plane (forward and backward at the hip). Dorsiflexion and plantarflexion are ankle movements. So the way the hip primarily moves in the horizontal plane is internal and external rotation.
