I haveseen cases which have developed from pressure during a long-continuedanaesthesia, the patient coming out of the anaesthetic to find his armparalyzed. The nerve may be injured in fractures of the middle thirdof the humerus. In one patient the administration of a hypodermicinjection in this region was followed by paralysis. The symptoms produced by musculospiral palsy are drop-wrist, withpronation, due to paralysis of the long extensors of the wrist and long Fig. Drop-wrist due to musculosiiiral paralysis. extensors of the fingers and thmnb, and weakness in flexion of theelbow from paralysis of the supinators. If the nerve is injured in theaxilla the triceps is also paralyzed. Sometimes in very slight casesthe supinator longus is not paralyzed. The position of the hand indrop-wrist is shown in Fig. 95. The action of the flexors of the handis apparently weak in grasping objects, but if the wrist be extended bythe examiner and held firmly in this position, the flexors are found toact in a normal manner. The awkward action of the forearm givesthe patient considerable discomfort, especially the loss of power ofsupination. After the drop-wrist has continued for some days aprominence appears upon the back of the hand as a result of the over-flexion of the wrist, due to a partial dislocation of one of the bones ofthe hand. But this subsides when recovery has taken place. Themuscles paralyzed show the reaction of degeneration, excepting in verylight c
