Children with X-shaped legs often suffer from a deficiency of vitamin D and calcium. Treatment typically involves supplementing with vitamin D and calcium. Before using corrective devices, it’s important to have a thorough check-up to understand the condition and severity of the leg deformity. Choose the appropriate treatment method based on the child’s age. In addition to professional treatment, traditional therapies can also be used in daily life to assist in treatment. However, attention should be given to a balanced diet, avoiding overeating or undereating, and refraining from binge eating and drinking.
