Calcium-deficiency rickets: vitamin D deficiency
Most children with vitamin D-deficient rickets will respond well to vitamin D and calcium, although response rates are higher with intramuscular than with oral treatment.[4]Nield LS, Mahajan P, Joshi A, et al. Rickets: not a disease of the past. Am Fam Physician. 2006 Aug 15;74(4):619-26.

Calcium-deficiency rickets: calcium deficiency
Calcium supplementation leads to relief of bone pain within 1 month, with improved mobility. Wrist enlargement may resolve within 6 months, although knee deformity may not resolve spontaneously.[43]Oginni LM, Sharp CA, Badru OS, et al. Radiological and biochemical resolution of nutritional rickets with calcium. Arch Dis Child. 2003 Sep;88(9):812-7.

Calcium-deficiency rickets: pseudovitamin D deficiency
A physiological dose of calcitriol generally promotes complete healing of the bone disease and resolution of the biochemical abnormalities.
Calcium-deficiency rickets: vitamin D resistance
Not all patients respond to oral treatment, but metabolic and bone abnormalities may improve with intravenous calcium.[44]Malloy PJ, Hochberg Z, Tiosano D, et al.

Hypophosphataemic rickets: X-linked, autosomal dominant, autosomal recessive, McCune-Albright syndrome
Many patients have impaired growth and bone healing despite treatment. Outcomes are better when treatment is started in early infancy, but skeletal development remains abnormal and early growth deficits may be permanent.[45]Mäkitie O, Doria A, Kooh SW, et al. Early treatment improves growth and biochemical and radiographic outcome in X-linked hypophosphatemic rickets. J Clin Endocrinol Metab. 2003 Aug;88(8):3591-7.

Hereditary hypophosphataemic rickets with hypercalciuria
Patients may respond to treatment. Spontaneous improvement in the renal phosphate-wasting defect has been reported in later life.[47]Econs MJ, McEnery PT.

Hypophosphataemic rickets: tumour-induced
Surgical removal of the tumour can cure rickets, but not all children have a complete response.[46]de Menezes Filho H, de Castro LC, Damiani D. Hypophosphatemic rickets and osteomalacia. Arg Bras Endocrinol Metabol. 2006 Aug;50(4):802-13.

Management of deformity
Untreated rickets can cause permanent bone deformity and lead to stunted growth. Surgical intervention may be necessary to repair severe bony abnormalities.[4]Nield LS, Mahajan P, Joshi A, et al. Rickets: not a disease of the past. Am Fam Physician. 2006 Aug 15;74(4):619-26.
