Rickets, known as nutritional vitamin D deficiency rickets, is a chronic nutritional disease characterized by skeletal lesions, caused by a deficiency of vitamin D in the body leading to disturbed calcium and phosphate metabolism. In the early stages of rickets, it is primarily due to insufficient levels of vitamin D, which then leads to abnormal calcium and phosphate metabolism; at this stage, it is necessary to consult the endocrinology department to correct it timely. If rickets has already caused developmental deformities of the bones, orthopedic consultation is required for corrective treatment. For instance, if children exhibit pigeon chest, or noticeable bow legs or knock knees, they need to see an orthopedic specialist.
