wrist drop. A condition in which the hand is flexed at the wrist and cannot be extended. It may be due to injury of the radial nerve or paralysis of the extensor muscles of the wrist and hand.
As stated above, the main cause of a Wrist Drop is overuse of the wrist whether it be with occupation or sports. Wrist drop may also be caused due to a trauma to the radial nerve by way of a cut or stab wound, or if a person suffers a gunshot wound to the wrist affecting directly the radial nerve. Another cause for a Wrist Drop is some sort of injury to the joint in the wrist or elbow resulting in persistent swelling of the elbow.
