If a partial contralateral C 7 nerve is transferred to a recipient injured nerve, results are not satisfactory. However, if an entire contralateral C 7 nerve is used to repair two nerves, both recipient nerves show good recovery. These findings seem contradictory, as the above two methods use the same donor nerve, only the cutting method of the contralateral C 7 nerve is different. To verify whether this can actually result in different repair effects, we divided rats with right total brachial plexus injury into three groups...

To understand the neural mechanisms underlying the therapeutic effects of crossing nerve transfer for brachial plexus injuries in human patients, we investigated the cortical responses after crossing nerve transfer in mice using conventional and tomographic optical imaging. The distal cut ends of the left median and ulnar nerves were connected to the central cut ends of the right median and ulnar nerves with a sciatic nerve graft at 8 weeks of age. Eight weeks after the operation, the responses in the primary somatosensory cortex (S1) elicited by vibratory stimulation applied to the left forepaw were visualized based on activity-dependent flavoprotein fluorescence changes...

Adult brachial plexus injuries frequently lead to significant and permanent physical disabilities. Investigating the mechanism of the injury using biomechanical approaches may lead to further knowledge with regard to preventing brachial plexus injuries. However, there are no reports of biomechanical studies of brachial plexus injuries till date. Therefore, the present study used a complex three-dimensional finite element model (3D-FEM) of the brachial plexus to analyze the mechanism of brachial plexus injury and to assess the validity of the model...

PURPOSE: Brachial plexus birth injuries with multiple nerve root avulsions present a particularly difficult reconstructive challenge because of the limited availability of donor nerves. The contralateral C7 has been described for brachial plexus reconstruction in adults but has not been well-studied in the pediatric population. We present our technique and results for retropharyngeal contralateral C7 nerve transfer to the lower trunk for brachial plexus birth injury. METHODS: We performed a retrospective review...

OBJECTIVE The object of this study was to assess the advantages and disadvantages of early nerve repair within 2 weeks following adult traumatic brachial plexus injury (ATBPI). METHODS From 2009 onwards, the authors have strived to repair as early as possible extended C-5 to C-8 or T-1 lesions or complete loss of C-5 to C-6 or C-7 function in patients in whom there was clinical and radiological suspicion of root avulsion. Among a group of 36 patients surgically treated in the period between 2009 and 2011, surgical findings in those who had undergone treatment within 2 weeks after trauma were retrospectively compared with results in those who had undergone delayed treatment...

Lymphangiomas are rare malformations of the lymphatic system and can often be found in the neck region, where its proximity to the brachial plexus may cause compressive neuropathy and possible iatrogenic injuries during dissection. We report 4 cases of lymphangiomas with compression of the brachial plexus that were successfully removed without permanent nerve injuries and present a literature review of the preoperative approach and surgical techniques. A preoperative multidisciplinary approach can help surgeons predict what they may encounter during the surgery...

Nerve transfers for brachial plexus reconstruction and the treatment of peripheral nerve injury have demonstrated excellent clinical outcomes and may be superior to nerve grafting. Previously described nerve transfers for restoration of elbow flexion include the Oberlin (ulnar to musculocutaneous) and double fasicular (median to biceps and ulnar to brachialis) transfers. However, these transfers cannot be performed in patients with loss of elbow flexion and concomitant high median and ulnar nerve injury. Other transfers utilizing the thoracodorsal or intercostal nerves have been described; however, this requires sacrifice of the latissimus dorsi muscle or potential nerve donors for a free, functioning gracilis muscle transfer...

Electrical current can cause neurological damage directly or by conversion to thermal energy. However, electrical injury causing isolated brachial plexus injury without cutaneous burns is extremely rare. We present a case of a 17-year-old boy who sustained accidental electrical injury to left upper extremity with no associated entry or exit wounds. Complete motor and sensory loss in upper limb were noted immediately after injury. Subsequently, the patient showed partial recovery in muscles around the shoulder and in ulnar nerve distribution at 6 months...

This mini review describes the current surgical strategy for restoring function after traumatic spinal nerve root avulsion in brachial or lumbosacral plexus injury in man. As this lesion is a spinal cord or central nervous injury functional return depends on spinal cord nerve cell growth within the central nervous system. Basic science, clinical research and human application has demonstrated good and useful motor function after ventral root avulsion followed by spinal cord reimplantation. Recently, sensory return could be demonstrated following spinal cord surgery bypassing the injured primary sensory neuron...

Particularly challenging after complete brachial plexus avulsion is reestablishing effective hand function, due to limited neurological donors to reanimate the arm. Acute repair of avulsion injuries may enable reinnervation strategies for achieving hand function. This patient presented with pan-brachial plexus injury. Given its irreparable nature, the authors recommended multistage reconstruction, including contralateral C-7 transfer for hand function, multiple intercostal nerves for shoulder/triceps function, shoulder fusion, and spinal accessory nerve-to-musculocutaneous nerve transfer for elbow flexion...

Axillary nerve injury is common after brachial plexus injuries, particularly with shoulder luxation. Nerve grafting is the traditional procedure for postganglionic injuries. Nerve transfer is emerging as a viable option particularly in late referrals. At the proximal arm the radial and axillary nerves lie close by. Sacrificing one of the triceps muscle nerve branches induces little negative consequences. Transferring the long head of the triceps nerve branch is a good option to recover axillary nerve function...

BACKGROUND: Root avulsion to all 5 roots of the brachial plexus is a common presentation and keeps a major reconstructive challenge. The contralateral C7 (CC7) nerve transfer has been used in treating brachial plexus avulsion injury (BPAI) since 1986. However, the effectiveness of the procedure remains a subject of controversy. The aim of this meta-analysis was to study surgical outcomes regarding motor and sensory recovery after CC7 nerve transfer. METHODS: Chinese or English (i...
