The gold standard of treatment for congenital clubfoot is the Ponseti series of manipulative correction plaster fixation. What parents should pay attention to after the cast: First, we should pay attention to observe whether the blood circulation of the toes is good or not, and find and deal with blood circulation disorders early. The method is to see, feel and press the three aspects of observation. Look at toe color, normal toe red, or light red for normal, if white, purple is abnormal, suggesting blood circulation disorders; touch cold, if toe warm for normal, cold for abnormal; pressure toe nail, normal pressure toe nail white, let go after 1, 2 seconds quickly red, and vice versa, if about 10 seconds is not red for abnormal. If it is still difficult to judge, it is easy to do the same observation by comparing the toes on the opposite side without a cast (if both feet are in a cast, you can observe the fingers for comparison). So how often should I observe? Within 6 hours after the first cast, we should observe every hour, not later than 2 hours. After that, it should be observed once every 2-4 hours. If any abnormality is found, the cast needs to be released immediately, and the cast can be released by soaking in warm water. The next day, go to the hospital to play the cast again. The second thing to observe is whether the cast is loose or not. Some children will try to get their toes back so as to release the cast, and it is a headache for both doctors and parents when they come across such a child, once he will release it once, it is almost certain that he will be able to release it every time, and some masters can even release it on the way home from the hospital. For such a child can only fight with him. Some of them are not able to finish taking off, but only take off their casts. Of course, some children just feel that the cast hinders their freedom of movement and cry in protest, so this situation should be differentiated.
