The development of postsurgical hypoparathyroidism is the most frequent complication of thyroidectomy and radical surgical procedures on the neck. Hypoparathyroidism is a disorder characterized by hypocalcemia, parathyroid hormone (PTH) deficiency, and abnormal bone remodeling. Standard treatment of hypoparathyroidism consists of oral calcium and active forms of vitamin D. However, some patients fail to achieve the normalization of calcium levels with this therapy. We present a clinical case of postsurgical hypoparathyroidism with severe clinical presentation of hypocalcaemia treated with recombinant human PTH 1-34 - teriparatide.
