Brachial plexus nerve transfers are referred to in this section as procedures utilized to treat brachial plexus injuries. Injuries to the brachial plexus have been separated into two categories: upper plexus injuries (C5, C6) and lower plexus injuries (C7, C8/T1). A common upper plexus injury is paralysis of the shoulder and elbow due to an upper trunk C5-C6 injury, also known as Erb’s palsy. Lower plexus injuries are associated with paralysis of the forearm, wrist, and/or hand due to middle trunk C7 and/or lower trunk C8-T1 injury. A combination of nerve transfers exists for these injury profiles. While there are common injury patterns to the brachial plexus, not all brachial plexus injuries are the same. Nerve transfers that are used for other brachial plexus injuries can be found in the Other Plexus Injuries section.
