[Origin unknown.]

For more information on rickets, visit Britannica.com.

Malformation of the bones in growing children due to deficiency of vitamin D, leading to poor absorption of calcium. In adults the equivalent is osteomalacia.

A deficiency disease of children whose bones do not harden and are deformed due to lack of vitamin D.

A condition caused by deficiency of vitamin D or calcium in infants and children, with disturbance in the mineralization of osseous and dental tissues. Marked by bending and bowing of bones, nodular enlargements at the ends of bones, myalgia, delay in closure of fontanels, and other problems. See also osteomalacia.

Deficiency disease of children in which bones do not harden and are deformed due to lack of vitamin D.

A disease of young growing animals caused by a nutritional deficiency of phosphorus or vitamin D. There is a failure of calcification of osteoid and cartilage of the bones which become bowed and a persistence with enlargement of the epiphyses so that the joints appear swollen. The animals are lame and dentition is delayed. Radiological examination shows a wider and thicker growth plate.

• adult r. — osteomalacia; a rickets-like disease affecting adults.
• fetal r. — see achondroplasia.
• hypervitaminosis D r. — deposition of large amounts of osteoid matrix in the metaphyses with a delay in its mineralization occurs in feeding excessive amounts of vitamin D.
• inherited r. — affected piglets are normal at birth but develop rickets indistinguishable from classical rickets. There is a defect in calcium absorption.
• renal r. — see renal secondary hyperparathyroidism.
• vitamin D-resistant r. — a condition almost indistinguishable from ordinary rickets clinically but resistant to unusually large doses of vitamin D; it is often familial but may occur sporadically. In hypophosphatemic vitamin D-resistant rickets, hypophosphatemia is the main characteristic, while in hypocalcemic vitamin D-resistant rickets, the serum concentration of phosphate is within normal limits or nearly so, and the concentration of calcium is abnormally low.
