How to put the stress piece of ankle varus

1. First, the patient lies on his back on the examination table, with his lower limbs straight and his toes pointing upward.

2. Secondly, the doctor turns the patient's ankle inward so that the sole of the foot is inward, while keeping the knee joint straight.

3. Then, under the condition of keeping the inversion position, the doctor holds the patient's heel and instep with his hand and applies a certain inversion stress to make the ankle joint in a tense state.

4. Finally, take X-ray photography. When shooting, it is necessary to aim the X-ray machine at the ankle joint, and take pictures from three directions: positive position, lateral position and oblique position.
