- n.a disease of childhood in which the bones do not harden due to a deficiency of vitamin D. Without vitamin D, not enough calcium salts are deposited in the bones to make them rigid: consequently they become soft and malformed. This is particularly noticeable in the long bones, which become bowed, and in the front of the ribcage, where a characteristic rickety ‘rosary’ may become apparent. The deficiency of vitamin D may be dietary or due to lack of exposure to sunlight, which is important in the conversion of vitamin D to its active form. In the UK rickets is more common in Asian immigrant families.Renal rickets is due to impaired kidney function causing bone-forming minerals to be excreted in the urine, which results in softening of the bones.
