Quizplus · Accepted Answer

A drop-wrist deformity is caused by damage to the radial nerve, which innervates the muscles responsible for wrist and finger extension. Damage to the ulnar nerve can result in a claw hand deformity, damage to the median nerve can result in a carpal tunnel syndrome or pronator teres syndrome, and damage to the musculocutaneous nerve can result in weakness of elbow flexion.
