Deficiency of vitamin D is probably the least common cause of rickets in western Europe and the United States. Recently, several patients have been reported from Scotland,1 but we are not aware of any that have been reported from New York city in the last ten years. Furthermore, we have not had a single patient in the Metabolic Bone Disease Clinic at the Hospital for Special Surgery since this specialty clinic was opened ten years ago in New York.
In this communication, we are briefly recording an instance of rickets due to vitamin D deficiency. We have taken the opportunity to measure urinary hydroxyproline (hypro) as well as glycylproline (glypro) before and during medication with physiological doses of vitamin D.
The patient was a 23-month-old Negro boy who presented with bowlegs. The product of a full-term pregnancy and normal delivery, with a birth weight of 2,437 gm
