| Abstract: | Episodes of unusual hypercalcemia have been described in three men, 15, 17, and 18 yr old, who had sustained physiologically complete transections of the spinal cord at the first, fourth, and fifth vertebral levels. The patients with injuries at C4 and C5 had been completely immobilized for 14 and 21 weeks when they developed hypercalcemia. The patient with the C1 injury had never been able to remain more than 1 hr in a wheelchair during the 16 months preceding the hypercalcemia episode. All three patients were in the post-onset period of increased bone resorption and at an age when bone turnover is increased. They had hypercalciuria when they developed a drastic reduction in renal and subsequently hypercalcemia.In the C5 patient short term treatments with anabolic steroids reduced the calcemia; his renal function improved and he has had no recurrence. In the C1 patient calcemia was reduced after removal of bladder and urethral calculi. In the C4 patient, treatment with anabolic steroids was not successful in reducing the calcemia because of irreversible renal insufficiency. In two patients the levels of serum parathyroid hormone and calcitonin were evaluated. PTH was in the normal range and CT in the high normal range. |
