Carpal Tunnel Syndrome Resulting from Hydroxyapatite Deposition

Abstract 

Hydroxyapatite deposition disease (HADD) is a rare cause of carpal tunnel syndrome. This is a case report of a 55-year-old male who presented with symptoms of carpal tunnel syndrome and was subsequently found to have HADD. The diagnosis of HADD is made by the identification of poorly defined cloudy calcifications on radiography of the hand and wrist. Management is usually with nonsteroidal anti-inflammatory drugs, but if the pain is refractory, more invasive methods are utilized.
