Hypoparathyroidism and Avascular Necrosis of the Hip Joint: A Case Report.

A 30-year-old man presented with left hip pain and was diagnosed with femoral head avascular necrosis associated with idiopathic hypoparathyroidism, hypocalcemia, and vitamin D deficiency. Treatment with calcium, calcitriol, analgesia, and physiotherapy improved symptoms. This case suggests hypoparathyroidism may play a role in the development of avascular necrosis.
