Hand of benediction

The hand of benediction results from prolonged compression or injury of the median nerve or the ulnar nerve at the forearm or elbow. With median nerve compression, the "benediction" sign only appears when the patient attempts to make a fist, but is not present with the hand open. With ulnar nerve compression, the "benediction" sign only appears when the patient attempts to extend all fingers, but is not present with the hand closed. The term "hand of benediction" more frequently refers to damage of the median nerve, however.
