Brachial plexus injury arm, lack of muscle control in the arm, hand, or wrist, and lack of feeling or sensation in the arm or hand. Although several mechanisms account for brachial plexus injuries, the most common is nerve compression or stretch. Infants, in particular, may suffer brachial plexus injuries during delivery and these present with typical patterns of weakness, depending on which portion of the brachial plexus is involved. The most severe form of injury is nerve root avulsion, which usually accompanies high-velocity impacts that commonly occur during motor-vehicle collisions or bicycle accidents. Based on the location of the nerve damage, brachial plexus
Brachial plexus block anesthetic close to this artery frequently leads to a good block of the brachial plexus. The axillary block is commonly performed due to its ease of performance and relatively high success rate. Disadvantages of the axillary block include inadequate anesthesia in the distribution of the musculocutaneous nerve. This nerve supplies motor function to the biceps, brachialis, and coracobrachialis muscles and one of its branches supplies sensation to the skin of the forearm. If the musculocutaneous nerve is missed, it may be necessary to block this nerve separately. This can be accomplished by using a peripheral nerve stimulator to identify the
