The treatment of skeletal deformities due to rickets primarily targets the underlying disease, utilizing high doses of vitamin D supplementation. Mild skeletal deformities can recover spontaneously after treatment or correct themselves during a child's growth. The deformed or painful areas must be immobilized until the medication takes significant effect, which could take weeks or months. For moderate cases of bowlegs or knock-knees, small splints can be used for nighttime immobilization, and massage can be used for correction. For severe cases of bowlegs or knock-knees, patients can wear specially made orthopedic shoes. Permanent deformities may be corrected later through osteotomy.
