Prolonged immobilization or physical inactivity has been shown to produce increased bone resorption due to enhanced osteoclastic activity and diminished bone formation. These skeletal changes are a typical complication in tetraplegic patients, who are at risk of developing hypocalcemia. Hypercalciuria is the most characteristic symptom. However, some patients develop hypercalcemia, which is infrequent in these patients, and the hypercalcemia can become a life-threatening complication. Until now, it has been unclear why a small percentage of immobilized patients develop hypercalcemia. Here we present a case of symptomatic hypercalcemia (serum calcium: 3.5 mM/l) following immobilization due to a critical illness polyneuropathy. The diagnosis could be established after malignant hypercalcemia, primary hyperparathyroidism, and other causes of hypercalcemia were excluded. Treatment with intravenous saline, furosemide, and calcitonin was not effective in lowering serum calcium. Treatment with pamidronate (Aredia) was successful and reduced the serum calcium to normal values.
