False-colour X-ray image of a hand showing osteomalacia, a softening of the bones caused by a vitamin D deficiency. Osteomalacia is the adult equivalent to rickets. Vitamin D, obtained either in the diet, or from sunshine, is necessary to the uptake of calcium from food. Absence of the vitamin leads to decalcification of the bony tissue & hence the softening of the bone. Original is bw picture m230/006.
