Presentation
Symptoms vary depending on the severity and location of the trauma; however, common symptoms include wrist drop (the inability to extend the wrist upward when the hand is palm down); numbness of the back of the hand and wrist; and inability to voluntarily straighten the fingers. Loss of extension is due to paralysis of the posterior compartment of forearm muscles; although the arm extensors are also innervated by the radial nerve, their innervation is usually spared.
