patients may more truly represent those with complete unilateral phrenic nerve injury because the accessory phrenic nerve was not spared when the phrenic nerve was harvested from the thoracic cavity. Clinical Material and Methods Between August 1999 and March 2001, a total of 15 patients with total brachial plexus avulsion injuries underwent full-length phrenic nerve transfer to MCN by means of VATS (13 men and two women; age range 17–38 years; average age of 27.4 years). Seven VATS were performed on the left side and eight on the right side. The average

T he treatment of complete BPAI is a demanding and difficult surgery in the upper extremity. Currently, nerve transfer is the main method of treating BPAI. 22 However, the traditional means of nerve transfer lead to poor functional recovery of hand prehension, mainly attributable to the long distance between the nerve anastomosis site and the reinnervated antebrachial muscle.

the same hemisphere, there can be long-range plasticity between cortical hemispheres. Most of the evidence comes from studies of direct cortical damage, such as stroke or cortical lesions in human and animal models. 1 , 4 , 8 , 25 Some studies have also explored interhemispheric cortical plasticity after peripheral nerve deafferentation, but little long-term motor cortex plasticity was involved. Brachial plexus root avulsion injury is a severe peripheral nerve deafferentation in which the nerves that bridge the CNS and one side of the upper limb are ruptured. The

approved by the Medical Committee. All patients had complete avulsion of the 5 roots of the upper limb diagnosed by clinical evaluation and electromyography studies before surgery. During the surgical treatment the whole brachial plexus was exposed, and a definitive diagnosis of root avulsions was made at operation because the C5–T1 nerve within the intervertebral foramen was absent. The nerve transfer operation was performed with contralateral C-7 root to the median nerve of the damaged brachial plexus. The ulnar nerve of the damaged limb was used to perform grafting

rhesus monkeys) has been used as a donor nerve for treating lumbosacral plexus avulsion or atonic bladder due to conus medullaris injury. 10 , 12 , 21 Second, the L-6 nerve is located in the middle of the sacral plexus nerves in rodents, just as the C-7 nerve is in the brachial plexus nerves. It was inferred that the L-6 nerve also overlapped with neighboring nerves and could readily compensate. Additionally, as the surgical procedure of L6-L6 could be completed intraspinally distal to the conus medullaris and performed directly, nerve grafts could be avoided

total root avulsion was confirmed during surgical exploration. All procedures were performed by the senior author (W.D.X.). All patients underwent CC7 to C7 nerve transfer, in addition to other nerve transfers, as part of the overall reconstructive plan. Of the 8 patients, 1 was lost to follow-up and 1 was excluded because of severe concomitant soft-tissue damage of the arm. Among the remaining 6 patients, 5 were male and 1 was female, and the mean age was 27.2 ± 9.0 years (range 18–43 years). The average interval from injury to operation was 2 ± 0.6 months (range 1
