Bone demineralization, a factor of increasing significance in the management of primary hyperparathyroidism.

TL;DRAbstract

The significance of bone demineralization was evaluated for 97 patients treated surgically for primary hyperparathyroidism since 1980. Of 31 patients studied by bone densitometry, 16 showed moderate to severe osteoporosis. In approximately 20% of the total group, bone demineralization, including a bone fracture problem in some, was the dominant or a major indication for operation. Serial bone studies in six patients taken preoperatively or in patients not operated on for primary hyperparathyroidism showed an average loss of bone mineral density of 0.9% per year, whereas in four patients treated surgically serial studies showed an average increase of 9.8% per year. Although estrogen intake reduced serum calcium levels, significant bone demineralization or fractures were present in four patients aged 40 to 59 years and in five patients more than 60 years of age who had taken estrogens for many years. We conclude that in primary hyperparathyroidism, bone demineralization (1) justifies sur
