Standard of shooting anterior and posterior ankle position

1. According to the information on the doctor's website, the X-ray film of ankle joint shows that the patient is lying on his back or sitting on a photographic bed, his lower limbs are straight, his long axis is parallel to the long axis of the irradiation field, his lower limbs and feet are slightly pronated 15 degrees, and his feet are in a natural flexion state.

2. Lateral radiograph of ankle joint: The examined side should lie on the photographic bed, with the opposite knee joint flexed forward, the lateral side of the lower limb of the examined side close to the bed surface, with the knee joint slightly flexed, the long axis of the lower leg parallel to the long axis of the irradiation field, and the lateral side of the ankle joint close to the bed surface, so that the connecting line between the medial and lateral ankles forms an included angle of 65438 05 degrees with the table surface, the lateral side of the ankle joint, the foot slightly flexed, and the plantar plane perpendicular to the bed surface.
