Bone scanning in metabolic and endocrine bone disease.

99mTc diphosphonate bone scanning has proved to be a sensitive, though nonspecific, way of detecting a wide variety of metabolic bone disorders. Classic scan appearances of generalized increased tracer uptake throughout the skeleton are found in many types of metabolic bone disease, and whole-body retention measurements can be used to detect early forms of disease. Focal disease identified on bone scanning such as pseudofractures and brown tumors are clearly identified on the 99mTc diphosphonate bone scan, with isotope scan changes preceding radiological changes by up to 18 months.

We have studied bone turnover and bone status in 29 patients with hip fractures and compared them with normal subjects and patients with arthritis of the hip. Markers for bone formation, bone Gla protein, alkaline phosphatase and whole body retention of 99mTc-diphosphonate, and fasting urinary hydroxyproline, a marker for bone resorption, were all significantly higher in the hip fracture group than in the control group. The serum concentrations of 1,25-dihydroxyvitamin D were similar in the three groups, whereas the serum 25-hydroxyvitamin D concentration in the control group was higher than in the patient groups.

WBR was corrected for total body bone mineral (TBBM) and UE for forearm bone mineral content (BMC). Both uncorrected and corrected retention measurements were highly significantly correlated to the biochemical markers (P less than 0.
