Avascular necrosis of the distal pole of the scaphoid

摘要

Avascular necrosis (AVN) of the scaphoid predominantly occurs in the proximal pole. Review of the literature revealed only six cases and all are suspect due to the lack of either MRI investigation or investigation of bleeding preoperatively. We report four new cases and one of them appears to be a real distal pole AVN of the scaphoid in the literature.
