Preiser disease

Medical condition

Preiser disease, or (idiopathic) avascular necrosis of the scaphoid, is a rare condition where ischemia and necrosis of the scaphoid bone occurs without previous fracture. It is thought to be caused by repetitive microtrauma or side effects of drugs in conjunction with existing defective vascular supply to the proximal pole of the scaphoid. MRI coupled with CT and X-ray are the methods of choice for diagnosis.
