Bone mineral content in hyperthyroid patients after combined medical and surgical treatment.

Abstract

Bone mineral content (BMC) and bone mineral concentration (BMC') of the forearm were determined by photon absorptiometry in 20 untreated hyperthyroid patients and in 33 patients previously treated for hyperthyroidism. In untreated hyperthyroidism a significant decrease was found in both BMC and BMC'. In treated hyperthyroidism BMC and BMC' were normalized. The findings suggest that a previous hyperthyroid state is not a risk factor for development of spontaneous fractures providing the hyperthyroid state is effectively treated.
