title: A Rare Case Report of Immobility-Induced Hypercalcemia in an Infant.
abstract: Immobility-induced hypercalcemia is a rare cause of hypercalcemia in children, and to our knowledge it has never been reported in an infant. Infants and children are in a state of high bone turnover. Therefore, they are prone to the imbalance of osteoblastic and osteoclastic activity that occurs with prolonged immobilization, leading to hypercalcemia. Here we present the case of an infant with hypercalcemia who presented with fatigue, irritability, and failure to thrive after prolonged immobilization. Therapeutic interventions were conservative and included hydration and increased mobility leading to complete resolution. This case highlights the importance of including this rare entity in a differential diagnosis of hypercalcemia as well as screening postsurgical patients with prolonged immobility for hypercalcemia.
