There are differences in appearance, localized muscle contractures, and the angle of rotation of the foot on X-ray. 1. Morphological differences: If the dorsum of the foot lands on the lateral side of the foot, this condition is usually pronation. In the case of hallux valgus, the foot usually lands on the medial side of the foot, and there is a clear difference in appearance between the two cases. 2. The local muscle contracture is different: the dorsal and posterior tibial muscles are not strong enough in the case of hallux valgus and pronator teres, which causes the deformity of hallux valgus and pronator teres. 3. Different rotational angles in X-ray examination of the foot: ectropion will be manifested as anterior rotation deformity in the X-ray examination film, while entropion will be manifested as posterior rotation deformity in the X-ray examination film. When the patient suffers from clubfoot or clubfoot, it is recommended that the patient go to the regular hospital in time. In order to avoid delays.
