Screening for subclinical osteomalacia in the elderly: normal ranges or pragmatism?

Although osteomalacia is known to be common in some sections of the elderly population, the disease is often subclinical and there is uncertainty about the point at which treatment is necessary. Identification and treatment of osteomalacia are inseparably bound; the response of varying degrees of subclinical disease to treatment with vitamin D or alfacalcidol is described here. The response is assessed in relation to a simply derived reference range based on standard biochemical measurements together with a Jamshidi needle biopsy of the iliac crest. Although this technique does not define a truly normal range it identifies a treatable abnormality which could form the basis of further study of the problem of subclinical osteomalacia in the elderly.
