Hello! Your child's condition cannot be judged simply. But if only the unit motor nerve is damaged, polio or motor neuron disease should be ruled out first. I suggest you consult a neurologist first. I don't think it belongs to orthopedics.

(Dr. Ren Gaohong solemnly reminds me that because I can't see the patient face to face, I can't fully understand the condition. The above suggestions are for reference only. Please go to the hospital for specific diagnosis and treatment under the guidance of a doctor! )
