Photon absorptiomerty was used to measure bone mass in the lumber vertebrae, proximal femur, mid- radius and distal radius in eight pairs of closely matched female patients with primary hyperparathyroidism before, and 1,3 and 6 months after operation. One of each pair was randomized to receive 3 g of oral calcium supplementation/ day for three months postoperatively, and the other to serve as control. After successful operations on the parathyroid, the bone mass in the lumber vertebrae, proximal femur, and distal increased by roughly 7% during the first six months in both the treated and the control patients.
This study shows that oral calcium supplementation after operation for hyperparathyroidism does not result in any additional increase in bone mass beyond the effect that is caused by the operation.
