Rickets is a nutritional disease caused by a deficiency in vitamin D, leading to disturbances in calcium and phosphorus metabolism and resulting in abnormal bone development. During the early and active stages, the X-ray shows no obvious abnormalities in bone development; it is primarily a conceptual metabolic disorder along with low levels of vitamin D. At this time, it is advisable to consult an endocrinology department. If there are sequelae and mild to moderate sequelae, rehabilitation methods are needed for correction, and at this point, a rehabilitation department should be consulted. If there are severe skeletal deformities, surgical correction may be necessary, and at this time, an orthopedic department should be consulted.
