Any peripheral nerve is potentially vulnerable to needle-induced injury during routine procedures such as phlebotomy,intravenous line placement, joint aspiration,or intramuscular injection.Neurologic sequelae can vary from minor motor or sensory abnormalities to complete paralysis or causalgia.The most commonly damaged nerves are the sciatic and the radial, as they are both in traditional areas for intramuscular injection.However, other nerves are also at risk,as shown in the following novel cases involving distal branches of the peroneal nerve,which,given their location,may be the most vulnerable nerves in the foot to be injured by needles used during the usual local diagnostic procedures. |
