Abstract
INTRODUCTION/AIMS The study aimed to visualize the changes in the facial muscles of patients with severe facial palsy who showed no improvement for more than 3 months on acute stage. METHODS The 102 patients with severe facial palsy over House-Brackmann grade IV or an 80% degenerative ratio on ENoG at the initial examination, who showed no improvement for more than 3 months on acute stage were indicated to undergo ultrasonography of the face to evaluate the facial muscles. RESULTS Muscular degeneration was observed in 537/918 muscles (58.5%). Muscle volume shrinkage was observed in 209/918 muscles (22.8%). Fascial adhesions were observed in 209/918 muscles (22.7%). Among all the muscles assessed for degenerative changes, zygomaticus major/minor was the most affected by degenerative changes (91.2%). Degenerative changes were observed in the levator labii superioris muscle in 84.3% patients. The shrinkage was most frequently observed in the zygomaticus major muscle (61/102 patients [59.8%]), followed by the zygomaticus minor muscle (43.1%). Shrinkage of the levator labii suprioris was observed in 24.5% patients. The zygomaticus major/minor muscle had the highest proportion of fascial adhesions in 61.8% and 66.7% patients respectively. The levator labii suprioris muscle showed the lowest proportion of fascial adhesions, with only 7.8% patients being affected. DISCUSSION This study confirmed that the zygomaticus major, zygomaticus minor, and levator labii suprioris muscles, which raise the corner of the mouth, are the first to degenerate in patients with severe facial paralysis. This study demonstrated that ultrasonography is a simple and non-invasive examination for facial paralysis.

Abstract
Introduction The objective of this study was to search existing literature on nerve reconstruction surgery in patients with obstetric brachial plexus palsy to determine whether treatment with supraclavicular exploration and nerve grafting produced better elbow flexion outcomes compared to intercostal nerve transfer. Methods This study was a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis for Individual Patient Data guidelines. A systematic search was conducted using multiple databases. An ordinal regression model was used to analyze the effect of using supraclavicular exploration and nerve grafting or intercostal nerve on elbow flexion with the two scores measured: elbow flexion Medical Research Council scores and Toronto active movements scale scores for elbow flexion. Results A final patient database from 6 published articles consisted of 83 supraclavicular exploration and nerve grafting patients (73 patients with Medical Research Council and 10 patients with Toronto score) and 7 published articles which consisted of 131 intercostal nerve patients (84 patients with Medical Research Council and 47 patients with Toronto scores). Patients who underwent supraclavicular exploration and nerve grafting presented with an average Medical Research Council score of 3.9 ± 0.72 and an average Toronto score of 6.2 ± 2.2. Patients who underwent intercostal nerve transfer presented with an average Medical Research Council score of 3.9 ± 0.71 and an average Toronto score of 6.4 ± 1.2. There was no statistical difference between supraclavicular exploration and nerve grafting and intercostal nerve transfer when utilizing Medical Research Council elbow flexion scores (ordinal regression: 0.3821, standard error: 0.4590, p = 0.2551) or Toronto Active Movement Scale score for elbow flexion (ordinal regression: 0.7154, standard error: 0.8487, p = 0.2188). Conclusion Regardless of surgical intervention utilized (supraclavicular exploration and nerve grafting or intercostal nerve transfers), patients had excellent outcomes for elbow flexion following obstetric brachial plexus palsy when utilizing Medical Research Council or Toronto scores for elbow flexion. The difference between these scores was not statistically significant. Type of study/Level of evidence Therapeutic Study: Investigating the Result of Treatment/level III.

Abstract
LEARNING OBJECTIVES After studying this article, the participant should be able to: 1. Describe methods of clinical evaluation for neurologic recovery in brachial plexus birth injury. 2. Understand the role of different diagnostic imaging modalities to evaluate the upper limb. 3. List nonsurgical strategies and surgical procedures to manage shoulder abnormality. 4. Explain the advantages and disadvantages of microsurgical nerve reconstruction and distal nerve transfers in brachial plexus birth injury. 5. Recognize the prevalence of pain in this population and the need for greater sensory outcomes evaluation. SUMMARY Brachial plexus birth injury (BPBI) results from closed traction injury to the brachial plexus in the neck during an infant's vertex passage through the birth canal. Although spontaneous upper limb recovery occurs in most instances of BPBI, some infants do not demonstrate adequate motor recovery within an acceptable timeline and require surgical intervention to restore upper limb function. This article reviews major advances in the management of BPBI in the past decade that include improved understanding of shoulder pathology and its impact on observed motor recovery, novel surgical techniques, new insights in sensory function and pain, and global efforts to develop standardized outcomes assessment scales.

Abstract
AbstractThe start of Stanford's brachial plexus birth palsy (BPBP) experience dates back to 1983, when Dr. Vincent Rod Hentz visited Dr. Alain Gilbert on sabbatical. Since then, our principles of care for patients with BPBP have evolved based on our group's longitudinal experience caring for children with the entire spectrum of sequelae that arise in children with BPBP. We base our clinical decision making on frequent serial examinations and use intraoperative evoked potentials to guide surgical decisions. Here, we discuss our current principles on surgical indications, timing of surgery, and preferred techniques for secondary surgery in patients with BPBP.

Abstract
Background Brachial plexus injuries are frequently encountered in the domain of plastic surgery, mostly secondary to road traffic accidents, gunshot injuries, or falls from a height. Many modalities have been described in the management, depending on the level and duration of the injury. C5, C6 and C5, C6, C7 are two common patterns in which nerve repair and transfers are described. At our center, we practice spinal accessory to suprascapular nerve transfer in all patients with upper trunk brachial plexus injury. There are two described approaches for the spinal accessory nerve to suprascapular nerve transfer, i.e. anterior or dorsal. The rationale for doing the posterior approach is that this approach avoids damaging the suprascapular nerve at its entrance in the suprascapular notch under the suprascapular ligament during exploration due to traction. Materials and methods This is a retrospective study with a consecutive sampling of 23 patients presenting at Liaquat National Hospital, Karachi, with upper trunk brachial plexus injuries during the time period from January 2016 to December 2017, i.e. two years. We divided these 23 patients into two groups, one with the anterior approach and the other with a dorsal approach for spinal accessory to suprascapular nerve transfer for shoulder abduction. The mean duration of post-surgical follow-up was from 18 to 24 months and recovery and functional outcomes were assessed. Results Out of the 23 patients that were included, 10 patients were operated on with an anterior approach and 13 with a posterior approach. Fifty percent (50%) of patients operated with the anterior approach and 84% of patients with the posterior showed the best motor grade recovery of M4, respectively, with better performance in patients with the posterior approach as compared to the anterior approach. Conclusion We advocate taking a posterior approach for spinal accessory to suprascapular nerve transfer for shoulder abduction, as it has shown better results with reliable outcomes concerning shoulder abduction, angle of abduction, and range of motion.

Abstract
Background Neonatal brachial plexus palsy (NBPP) is a serious complication of high‐risk deliveries with controversy surrounding timing of corrective nerve surgery. This review systematically examines the existing literature and investigates correlations between age at time of upper trunk brachial plexus microsurgery and surgical outcomes. Methods A systematic screening of PubMed, Cochrane, Web of Science, and CINAHL databases using PRISMA‐IPD guidelines was conducted in January 2020 to include full‐text English papers with microsurgery in upper trunk palsy, pediatric patients. Spearman rank correlation analysis and two‐tailed t‐tests were performed using individual patient data to determine the relationship between mean age at time of surgery and outcome as determined by the Mallet, Medical Research Council (MRC), or Active Movement Scale (AMS) subscores. Results Two thousand nine hundred thirty six papers were screened to finalize 25 papers containing individual patient data (n = 256) with low to moderate risk of bias, as assessed by the ROBINS‐I assessment tool. Mallet subscore for hand‐to‐mouth and shoulder abduction, AMS subscore for elbow flexion and external rotation, and MRC subscore for elbow flexion were analyzed alongside the respective age of patients at surgery. Spearman rank correlation analysis revealed a significant negative correlation (ρ = −0.30, p < .01, n = 89) between increasing age (5.50 ± 2.09 months) and Mallet subscore for hand‐to‐mouth (3.43 ± 0.83). T‐tests revealed a significant decrease in Mallet hand‐to‐mouth subscores after 6 months (p < .05) and 9 months (p < .05) of age. No significant effects were observed for Mallet shoulder abduction, MRC elbow flexion, or AMS elbow flexion and external rotation. Conclusion The cumulative evidence suggests a significant negative correlation between age at microsurgery and Mallet subscores for hand‐to‐mouth. However, a similar correlation with age at surgery was not observed for Mallet shoulder abduction, MRC elbow flexion, AMS external rotation, and AMS elbow flexion subscores.

Abstract
Resumo
Objetivo Avaliar a flexão do cotovelo em crianças portadoras de paralisia obstétrica do plexo braquial submetidas à transferência de Oberlin.
Métodos Estudo retrospectivo com 11 pacientes acometidos por paralisia decorrente do trabalho de parto e que não apresentaram recuperação espontânea da flexão do cotovelo até os 12 meses de vida, operados entre 2010 e 2018.
Resultados As crianças foram operadas entre os 5 e 12 meses de vida, com média de 7,9 meses e o tempo médio de seguimento foi de 133,2 meses, variando de 37 a 238 meses. Seis pacientes (54,5%) apresentaram grau de força muscular ≥ 3, medido pela escala de força do Medical Research Council (MRC), e, pela escala de movimentação ativa (Active Momement Scale [AMS]), 5 pacientes obtiveram pontuação ≥ 5. Foi identificada correlação negativa entre a AMS e a classificação de Narakas (r = -0,509), bem como entre a MRC e a classificação de Narakas (r = -0,495). Já entre a AMS e a MRC, foi observada forte correlação positiva (r = 0,935), demonstrando que quanto maior a pontuação na escala de movimento, maior será a pontuação na escala de força muscular.
Conclusão A cirurgia de Oberlin apresenta-se como uma opção possível para a recuperação da flexão do cotovelo em crianças com plexopatia neonatal; no entanto, demonstra resultados bastante heterogêneos, mesmo no seguimento a longo prazo.

Abstract
Upper brachial plexus injury or isolated lesions of the axillary nerve (AN) compromise shoulder functionality significantly. Different surgical techniques have been described for selective reconstruction of the AN, with good results especially in association with repair of the suprascapular nerve. The objective of this study is to describe the transfer of motor fascicles of the median nerve to the AN by an axillary approach in cadavers and the clinical results in 2 patients. Dissections were performed on 5 cadavers, followed by identification and dissection of the AN and its divisions before entering the quadrangular space. We standardized the surgical technique in which the median nerve was first identified and then an intrafascicular dissection was performed. Then we harvested a fascicle and transferred it to the anterolateral branch of the AN. Two patients underwent an operation; at 2 years of follow-up, average abduction of 125 degrees and external rotation of 95 degrees were observed. In conclusion, the transfer of motor fascicles of the median nerve to the AN by an axillary approach could be an alternative technique for the deltoid reinnervation in upper brachial plexus injury. Some advantages are the proximity of the donor nerve to the receptor nerve and the low morbidity of the target muscles of the donor nerve. Studies with a larger number of patients are required to establish its effectiveness compared with other techniques already described.

Abstract
Neuroplasticity is the capacity of the central nervous system to adapt to external or internal stimuli. It is being increasingly recognized as an important factor which contributes to the successful outcome of nerve transfers. Other much more well-known factors are the number of axons that cross the coaptation site, the interval between trauma and repair, and age. Neuroplasticity is mediated by synaptic and neurotransmitter changes which underlie activation of previously existing but low-active connections in the brain. Dendritic sprouting and axonal elongation might also take place, but is likely less prominent. We review different factors that play a role in neuroplasticity and functional regeneration after specific nerve transfers. These factors include, amongst others, the distance between cortical areas of the donor and receptor neurons; the presence versus absence of pre-existing low-active inter-neuronal connections; gross versus fine movement restoration; rehabilitation; brain trauma and also very important: the age. The potential for plastic adaptation should be taken into consideration if the surgical strategy and post-operative rehabilitation are planned, as its influence on results cannot be denied.

Abstract
BACKGROUND The purpose of this article is to systematically review the peer-reviewed literature on the morbidity of nerve transfers performed in patients with brachial plexus birth injury (BPBI). Nerve transfers for restoration of function in patients with BPBI that fail nonoperative management are increasing in popularity. However, relatively little attention has been paid to the morbidity of these transfers in the growing patient. The authors systematically review the current literature regarding donor site morbidity following nerve transfer for BPBI. METHODS A systematic review of the Medline and EMBASE databases was conducted through February 2020. Primary research articles written in English and reporting donor site morbidity after nerve transfer for BPBI were included for review. RESULTS Thirty-six articles met inclusion criteria, all of which were retrospective reviews or case reports. There was great heterogeneity in outcomes assessed. With 5 year or less follow-up, all transfers were relatively well tolerated with the exception of the hypoglossal nerve transfer. CONCLUSION Nerve transfers are a well-recognized treatment strategy for patients with BPBI and have an acceptable risk profile in the short term. Full hypoglossal nerve transfers for BPBI are of historical interest. Donor site morbidity is grossly underreported. This review highlights the need for more objective and systematic reporting of donor site outcomes, and the need for longer term follow-up in these patients. LEVEL OF EVIDENCE Systematic review. Level III-therapeutic.

Abstract
PURPOSE Long-term evaluation of hand function in children who underwent transfer procedures to reinnervate the biceps muscle, using fascicles from the ulnar and median nerves as donors. METHODS In the last follow-up evaluation, the children underwent a neurological examination, and their hand status was classified according to the Raimondi grading system for hand function. Two physical measurements, the child health assessment questionnaire (CHAQ) and the Sollerman hand function test, were applied to assess upper extremity function. RESULTS Eight children were re-evaluated. In four the donor fascicle was from the ulnar nerve and in four from the median nerve. The average interval between surgery and the last evaluation was 8.3 years (range 6-10 years). Five patients scored 5 points in the Raimondi grading system, and 3 patients scored 4 points. The results from the CHAQ ranged from 0.03 to 0.41. The results from the Sollerman test were between 60 and 77 for the affected upper limb and between 65 and 79 for the dominant upper limb. CONCLUSION Nerve transfer of a fascicle from the ulnar or median nerve to the biceps motor branch in children with neonatal brachial plexus palsy does not result in hand dysfunction.

Abstract
PURPOSE Elbow flexion is a key indicator of functional recovery in obstetric brachial plexus palsy (OBPP). However, lack of flexion could be a result of an entrapped musculocutaneous nerve during the healing period. The purpose of this study was to investigate the possible compression of the musculocutaneous nerve and outcomes of decompression. METHODS The study included 11 children aged with a mean age of 10.9 ± 2.7 months (range, 8-16 months) with Narakas 2 involvement OBPP, who had insufficient elbow flexion but had satisfactory shoulder abduction. Prior to surgery, magnetic resonance imaging (MRI) was performed to identify the entrapment. The children were evaluated pre-operatively and at 3 and 12 months postoperatively using the Active Movement Scale and Faradic Excitability Test. The musculocutaneous nerve was explored and decompressed in all the children. Regular physiotherapy and a home exercise programme were prescribed after surgery. RESULTS The MRI findings were consistent with the surgical exploration in all the infants. Statistical analyses showed that decompression of the musculoskeletal nerve improved active movement scale scores on elbow flexion and faradic excitability test values of biceps brachii within 3 months after surgery. CONCLUSION Children with delayed elbow flexion and satisfactory shoulder abduction may have an entrapped musculocutaneous nerve in the proximal arm and decompression of the nerve improves elbow function.

Abstract
Nerve regeneration is a key biological process in those recovering from neural trauma. From animal models it is known that the regenerative capacity of the peripheral nervous system (PNS) relies heavily on the remarkable ability of Schwann cells to undergo a phenotypic shift from a myelinating phenotype to one that is supportive of neural regeneration. In rodents, a great deal is known about the molecules that control this process, such as the transcription factors c-Jun and early growth response protein 2 (EGR2/KROX20), or mark the cells and cellular changes involved, including SOX10 and P75 neurotrophin receptor (p75NTR). However, ethical and practical challenges associated with studying human nerve injury have meant that little is known about human nerve regeneration.The present study addresses this issue, analysing 34 denervated and five healthy nerve samples from 27 patients retrieved during reconstructive nerve procedures. Using immunohistochemistry and Real-Time quantitative Polymerase Chain Reaction (RT-qPCR), the expression of SOX10, c-Jun, p75NTR and EGR2 was assessed in denervated samples and compared to healthy nerve. Nonparametric smoothing linear regression was implemented to better visualise trends in the expression of these markers across denervated samples.It was found, first, that two major genes associated with repair Schwann cells in rodents, c-Jun and p75NTR, are also up-regulated in acutely injured human nerves, while the myelin associated transcription factor EGR2 is down-regulated, observations that encourage the view that rodent models are relevant for learning about human nerve injury. Second, as in rodents, the expression of c-Jun and p75NTR declines during long-term denervation. In rodents, diminishing c-Jun and p75NTR levels mark the general deterioration of repair cells during chronic denervation, a process thought to be a major obstacle to effective nerve repair. The down-regulation of c-Jun and p75NTR reported here provides the first molecular evidence that also in humans, repair cells deteriorate during chronic denervation.

Abstract
BACKGROUND Obstetric brachial plexus palsy is caused by traction during birth. Most patients regain useful function with spontaneous recovery. In some cases, cross reinnervation occurs between the biceps and triceps muscles. In these cases, smooth active motion of the elbow joint is impaired by simultaneous biceps and triceps muscle contraction. The biceps and triceps muscle cocontraction could be treated by botulinum toxin type A injection, tendon transfer of the triceps to biceps, and intercostal nerves transfer to the musculocutaneous nerve (MCN) or to the motor branch of the radial nerve to the triceps muscle. PATIENTS AND METHODS We present 16 cases (10 males and 6 females) with biceps and triceps cocontraction in spontaneously recovered obstetric brachial plexus palsy patients. They were treated by 3 intercostal nerves transfer to MCN without exploration of the remaining plexus. The mean age at surgery was 40.6 months (range, 24-65 months). Preoperative electromyography was done in all cases to confirm biceps and triceps cocontraction and to assess the contractile status of both muscles. RESULTS The mean postoperative follow-up period was 51.7 months (range, 27-64 months). At the final follow-up, elbow flexion was graded 3 in 1 patient, grade 4 in 3 patients, grade 6 in 9 patients, and grade 7 in 3 patients using the 7-point Toronto scale. The mean active range of motion of the elbow (against gravity) increased from 38 degrees preoperatively (range, 0-75 degrees) to 96.8 °[Combining Ring Above] at the final follow-up (range, 60-140 degrees). CONCLUSIONS Intercostal nerves transfer to MCN for management of biceps, and triceps cocontraction in spontaneously recovered obstetric brachial plexus injury is a good option with minimal morbidity and high success rate.

Abstract
BACKGROUND Functional elbow flexion recovery is one of the main goals of neonatal brachial plexus palsy (NBPP) reconstruction. The current neurosurgical treatment options include nerve grafting and nerve transfer. OBJECTIVE The present study sought to examine the literature for comparison of functional elbow flexion recovery in NBPP following nerve grafting or nerve transfer. We conducted a systematic literature review and meta-analysis according to PRISMA guidelines. A search was conducted on Pubmed/Medline and Cochrane for eligible studies published until November of 2018. Odd ratios (OR) and 95% confidence intervals (CI) were calculated to compare functional elbow flexion outcomes between nerve graft and nerve transfer. A random effects model meta-analysis was conducted. A Medical Research Council (MRC) score ≥ 3 or Active Movement Scale (AMS) ≥ 5 was considered a functional recovery of elbow flexion. RESULTS The present study included 194 patients from 1990 to 2015 across five observational trials. Only pediatric patients with obstetric brachial plexus injury were included. The mean patient age at surgery varied between studies from 5.7 months to 11.9 months and mean follow-up from 12 to 70 months. No complications or cases of donor site morbidity were reported. From the included studies, 118 patients were reported with MRC or AMS scoring usable for odd ratio comparison. Functional recovery occurred with nerve transfer in 95.2% of patients (n = 59/62) and with nerve grafting in 96.4% of patients (n = 54/56). Overall, the outcomes for elbow flexion between the groups appeared similar (OR 1.15, 95% CI 0.19-7.08, I2 2.9%). CONCLUSION Comparing nerve grafting and nerve transfer for NBPP, there is no statistically significant difference in functional elbow flexion recovery.

Abstract
BACKGROUND Arthrogryposis multiplex congenita (AMC) is a rare disease which affects mainly upper and lower extremities. Affected patients are not able to eat unassisted due to elbow contracture and nonexistent active elbow flexion. In traumatic brachial plexus palsies, a nerve transfer from either median or ulnar nerve to the musculocutaneous nerve has proved to induce active elbow flexion, and we report our results of such a procedure in a nontraumatic condition, that is, arthrogryposis. METHODS We selected four patients with AMC type 1 (6 extremities, 2 males, 2 females) diagnosed with AMC presenting to our institution shortly after birth from 2014 to 2016 to perform a nerve transfer from the median nerve to the musculocutaneous nerve in order to induce active elbow flexion. The indication of application of this surgical procedure was based on active finger and wrist flexion, limited contracture of elbow joints and evidence of flexing muscle fibers detected by sonography. RESULTS Five nerve transfers were conducted with a follow up of 2-5 years. Two extremities reached active elbow flexion motorgrade M4, two M3, and one M1 at latest follow up. One patient developed a postoperative suture granuloma. One nerve transfer was abandoned due to neuroanatomic variation. One extremity was treated with botulinum toxin in triceps muscle in addition to the nerve transfer. CONCLUSIONS In this series of selected cases of AMC Type 1 we were able to induce active elbow flexion using a nerve transfer technique developed for traumatic and obstetric brachial plexus palsies. In four extremities the procedure achieved independent hand-to-mouth active elbow flexion. Level of evidence four.

Abstract
A 25-year-old man sustained a right-sided brachial plexus injury from a high-velocity motocross accident. Physical examination and electromyography were consistent with a pan-brachial plexopathy with no evidence of axonal continuity. The patient underwent a spinal accessory to suprascapular nerve transfer and an intercostal to musculocutaneous nerve transfer with interpositional sural nerve grafts. He recovered MRC 4/5 elbow flexion and MRC 2/5 shoulder abduction and external rotation. Twenty-two months post-injury the patient displayed a flicker of flexion of his flexor pollicis longus and flexor digitorum profundus to his index finger - he went on to recover a functional pinch. Thirty-six months post-injury the patient displayed a flicker of contraction in brachioradialis with motor unit potentials on electromyography. This case demonstrates that some patients may have capacity for functional recovery after prolonged denervation and highlights the potential impact of anatomical anomalies in the assessment and treatment of peripheral nerve injuries.

Abstract
PURPOSE The outcome from microsurgical reconstruction of neonatal brachial plexus palsy (NBPP) varies, and comparison between different series is difficult, given the differences in preoperative evaluation, surgical strategies, and outcome analysis. To evaluate our results, we reviewed a series of children who underwent surgical treatment in a period of 14 years. METHODS We made a retrospective review of 104 cases in which microsurgical repair of the brachial plexus was performed. Strength was graded using the Active Movement Scale. Whenever possible, upper palsies underwent surgery 4 to 6 months after birth and total lesions around 3 months. The lesions were repaired, according to the type of injury: neurolysis, nerve grafting, nerve transfer, or a combination of techniques. The children were followed for at least 24 months. RESULTS The majority of cases were complete lesions (56/53.8%). Erb's palsy was present in 10 cases (9.6%), and 39 infants (37.5%) presented an extended Erb's palsy. The surgical techniques applied were neurolysis (10.5%), nerve grafts (25.9%), nerve transfers (34.6%), and a combination of grafts and transfers (30.7%). The final outcome was considered poor in 41.3% of the cases, good in 34.3%, and excellent in 24%. A functional result (good plus excellent) was achieved in 58.3% of the cases. CONCLUSIONS There is no consensus regarding strategies for treatment of NBPP. Our surgical outcomes indicated a good general result comparing with the literature. However, our results were lower than the best results reported. Maybe the explanation is our much higher number of total palsy cases (53.8% vs. 25% in the literature).

Abstract
BACKGROUND AND IMPORTANCE The use of nerve transfers to restore nerve function following traumatic avulsion injuries has been described, though there is still a paucity in the literature documenting technique and long-term outcomes for these procedures. The double Oberlin nerve transfer involves transferring fascicles from the median and ulnar nerves to the musculocutaneous nerve to restore elbow flexion in patients with a C5-C6 avulsion injury. The purpose of this case report is to present our indications and technique for a double Oberlin transfer in addition to exhibiting video footage at follow-up time points documenting the incremental improvement in elbow flexion following the injury. CLINICAL PRESENTATION The patient is a 25-yr old, left-hand dominant male who presented 5 mo following a motor vehicle accident. He had 0/5 biceps muscle strength on the left with a computed tomography myelogram that demonstrated pseudomeningoceles from C2-C3 to C7-T1 with root avulsions of C5 and C6. He was subsequently indicated for a double Oberlin nerve transfer to restore elbow flexion. CONCLUSION In this case report, we present our technique and outcomes for a double Oberlin transfer with restoration of elbow flexion at 1-yr follow-up for a patient with traumatic brachial plexus injury. We believe that the double Oberlin transfer serves as a safe and effective method to restore elbow flexion in this patient population.

Abstract
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. Any child aged less than 2 years was included. Charts were analyzed for patient demographic data, operative variables, functional outcomes, complications, and length of follow-up. RESULTS We had a total of 5 patients. Average nerve graft length was 3 cm. All patients had return of hand sensation to the ulnar nerve distribution as evidenced by a pinch test, unprompted use of the recipient limb without mirror movement, and an Active Movement Scale (AMS) of at least 2/7 for finger and thumb flexion; one patient had an AMS of 7/7 for finger and thumb flexion. Only one patient had return of ulnar intrinsic hand function with an AMS of 3/7. Two patients had temporary triceps weakness in the donor limb and one had clinically insignificant temporary phrenic nerve paresis. No complications were related to the retropharyngeal nerve dissection in any patient. Average follow-up was 3.3 years. CONCLUSIONS The retropharyngeal contralateral C7 nerve transfer is a safe way to supply extra axons to the severely injured arm in brachial plexus birth injuries with no permanent donor limb deficits. Early functional recovery in these patients, with regard to hand function and sensation, is promising. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic V.

Abstract
OBJECTIVE The use of nerve transfers versus nerve grafting for neonatal brachial plexus palsy (NBPP) remains controversial. In adult brachial plexus injury, transfer of an ulnar fascicle to the biceps branch of the musculocutaneous nerve (Oberlin transfer) is reportedly superior to nerve grafting for restoration of elbow flexion. In pediatric patients with NBPP, recovery of elbow flexion and forearm supination is an indicator of resolved NBPP. Currently, limited evidence exists of outcomes for flexion and supination when comparing nerve transfer and nerve grafting for NBPP. Therefore, the authors compared 1-year postoperative outcomes for infants with NBPP who underwent Oberlin transfer versus nerve grafting. METHODS This retrospective cohort study reviewed patients with NBPP who underwent Oberlin transfer (n = 19) and nerve grafting (n = 31) at a single institution between 2005 and 2015. A single surgeon conducted intraoperative exploration of the brachial plexus and determined the surgical nerve reconstruction strategy undertaken. Active range of motion was evaluated preoperatively and postoperatively at 1 year. RESULTS No significant difference between treatment groups was observed with respect to the mean change (pre- to postoperatively) in elbow flexion in adduction and abduction and biceps strength. The Oberlin transfer group gained significantly more supination (100° vs 19°; p < 0.0001). Forearm pronation was maintained at 90° in the Oberlin transfer group whereas it was slightly improved in the grafting group (0° vs 32°; p = 0.02). Shoulder, wrist, and hand functions were comparable between treatment groups. CONCLUSIONS The preliminary data from this study demonstrate that the Oberlin transfer confers an advantageous early recovery of forearm supination over grafting, with equivalent elbow flexion recovery. Further studies that monitor real-world arm usage will provide more insight into the most appropriate surgical strategy for NBPP.

Abstract
PURPOSE Nerve transfers to restore elbow flexion have been described for traumatic brachial plexus palsy in adults. Indications are less frequent in infants and the results are less published. METHODS Ten patients with obstetrical brachial plexus palsy were operated on for lack of flexion against gravity with ulnar or median nerve transfer to biceps motor branch. The primary endpoint was improvement in elbow flexion and supination. RESULTS Mean age at surgery was 12.5 months and mean follow-up was 2.6 years. The Active Movement Scale (AMS) was used to evaluate elbow flexion and forearm supination. At the last follow-up, the average AMS score improved from 0.3 to 5.7 for elbow flexion and from 0.6 to 5.8 for forearm supination. There was no statistical correlation between the age at surgery and the AMS score 18 months post-operatively. CONCLUSIONS Nerve transfer to the biceps motor branch can improve elbow flexion and forearm supination in selected patients with upper lesions and can be safely performed until the age of two years.

Abstract
The primary goal of the surgical treatment of upper brachial plexus injuries is to restore active elbow flexion. Accordingly, Oberlin's transfer has been frequently performed since 1994 and has influenced the development of other nerve transfers. However, the window of opportunity for nerve transfers remains a subject of controversy. The objective of this study was to assess magnetic resonance (MR) neurographic, clinical and electrophysiological long-term results after Oberlin's transfer. For this purpose, we performed a retrospective follow-up study. Six patients with upper brachial plexus or musculocutaneous nerve injuries were assessed; 2 were iatrogenic nerve injuries following shoulder arthroscopy or neurofibroma resection. Direct and indirect signs of neuropathy were objectified with MR neurography. Moreover, clinical and electrodiagnostic follow-up was performed and all patients completed the Disabilities of Arm, Shoulder and Hand score. Mean follow-up was 48 ± 21.9 (range, 20-73) months. Mean age was 40 ± 11.3 years and mean delay to surgery was 9 ± 3.2 months. All patients were satisfied with the functional results and the median Disabilities of Arm, Shoulder and Hand score was 21 (range, 1-57). Biceps strength was improved in 5 patients from Medical Research Council grade M0 to M4-5 and in one patient to M2-3. The donor nerve showed normal motor and sensory action potentials. Follow-up MR neurography demonstrated biceps reinnervation. Taken together, this study reports good long-term results after Oberlin's transfer. MR neurography represents an excellent, noninvasive preoperative planning tool and can be of high value in selected postoperative cases. The combined evaluation of nerves and muscles may help to indicate nerve transfers in delayed cases.

Abstract
OBJECTIVE Neuroplasticity is analyzed in this article as the capacity of the CNS to adapt to external and internal stimuli. It is being increasingly recognized as an important factor for the successful outcome of nerve transfers. Better-known factors are the number of axons that cross the coaptation site, the time interval between trauma and repair, and age. Neuroplasticity is mediated initially by synaptic and neurotransmitter changes. Over time, the activation of previously existing but lowly active connections in the brain cortex contributes further. Dendritic sprouting and axonal elongation might also take place but are less likely to be prominent. METHODS The authors reviewed different factors that play roles in neuroplasticity and functional regeneration after specific nerve transfers. RESULTS The authors found that these different factors include, among others, the distance between cortical areas of the donor and receptor neurons, the presence versus absence of preexisting lowly active interneuronal connections, gross versus fine movement restoration, rehabilitation, brain trauma, and age. CONCLUSIONS The potential for plasticity should be taken into consideration by surgeons when planning surgical strategy and postoperative rehabilitation, because its influence on results cannot be denied.

Palispis WA, Gupta R. Surgical repair in humans after traumatic nerve injury provides limited functional neural regeneration in adults. Exp Neurol 2017; 290:106-114.

Abstract
Traumatic nerve injuries result in devastating loss of neurologic function with unpredictable functional recovery despite optimal medical management. After traumatic nerve injury and denervation, regenerating axons must traverse a complex environment in which they encounter numerous barriers on the way to reinnervation of their target muscle. Outcomes of surgical intervention alone have unfortunately reached a plateau, resulting in often unsatisfactory functional recovery. Over the past few decades, many improvements were developed to supplement and boost the results of surgical repair. Biological optimization of Schwann cells, macrophages, and degradation enzymes have been studied due to the key roles of these components in axonal development, maintenance and response to injury. Moreover, surgical techniques such as nerve grafting, conduits, and growth factor supplementation are also employed to enhance the microenvironment and nerve regeneration. Yet, most of the roadblocks to recovery after nerve injury remain unsolved. These roadblocks include, but are not limited to: slow regeneration rates and specificity of target innervation, the presence of a segmental nerve defect, and degeneration of the target end-organ after prolonged periods of denervation. A recognition of these limitations is necessary so as to develop new strategies to improve functional regeneration for these life changing injuries.

Abstract
UNLABELLED The purpose of this study was to examine the results of spinal accessory nerve to suprascapular nerve (with or without axillary nerve neurotization) and an Oberlin transfer as primary treatment in children with Narakas type I obstetric brachial plexus injuries, when parents refused to consent to conventional nerve trunk-/root-level reconstruction. A total of 20 children with poor shoulder abduction and no biceps antigravity function but with good hand function were treated with spinal accessory nerve to suprascapular nerve and an Oberlin transfer at a mean age of 5.8 months (SD 3.27; range 3-12.) All the patients were evaluated at a mean of 2.8 years (SD 0.8; range 1.5 to 3.8) post-operatively. Three patients were lost to follow-up. Of the remainder, 11 had grade 4+ power of elbow flexion and six patients had grade 4 power at 1 year follow-up; all had 4+ power of elbow flexion at final follow-up. At final follow-up the Mallet score was a mean of 15; (SD 4.22, range 9 to 20). Primary distal nerve transfers can give good outcomes in patients with obstetric brachial plexus injuries and may be an alternative to surgery on the nerve trunks LEVEL OF EVIDENCE IV.

Abstract
PURPOSE Most cases of obstetric brachial plexus palsy (OBPP) involve C5 and C6 nerve roots (Erb's palsy). In those cases, re-establishing the elbow flexion is the primary goal of surgery. The partial transfer of the ulnar nerve to the musculocutaneous nerve (Oberlin's procedure) is widely used in adults, but incipient in children. The purpose of this study is to describe the results obtained with such procedure as regards the improvement of the elbow flexion and donor nerve morbidity. METHOD Thirteen children aged 9 to 15 months underwent Oberlin's procedure. They were assessed preoperatively and 1 year postoperatively using the active movement scale and also according to the functionality of the affected limb. All of them were evaluated because of the possibility of movement loss resulting from the donor nerve. We used the non-parametric, statistic Wilcoxon signed rank test (α = 0,05) method. RESULTS There was a significant improvement in the active elbow flexion between pre- and postoperative periods. Eleven children presented functional improvement. All of them maintained negative cookie test 1 year after the surgery. We did not observe any loss related to the donor nerve in terms of wrist flexion. CONCLUSION The results suggest that Oberlin's procedure can be an effective and safe alternative to treat elbow flexion in Erb's palsy.

Abstract
PURPOSE This study aimed to investigate the functional outcomes of infants who underwent neurotization for shoulder abduction and elbow flexion in Narakas grade 1 birth-related brachial plexus palsy (BRBPP) and compare this cohort to children who progressed past the point of needing intervention. METHODS A cohort study was conducted at a single center between 1999 and 2010. Two-hundred and eight infants were identified with BRBPP that presented for neurosurgical care as infants. Of those, 38 (18 %) received neurosurgical intervention with approximate 2-year follow-up. Only infants undergoing cranial nerve XI to suprascapular nerve neurotization for shoulder abduction (SA) weakness and medial pectoral nerve to musculocutaneous nerve neurotization for elbow flexion (EF) weakness were included. In addition, 30 infants who improved past the need for surgical intervention and had been followed for close to 24 months were identified for comparison. Descriptive statistics and exploratory analysis were performed using SAS 9.2 and JMP 9.0.2. RESULTS Shoulder abduction For SA, there were no differences in age at presentation between the operative (6-9 months) and non-operative (5-9 months) groups (p = 0.99). Infants in the operative cohort had significantly worse initial function (p = 0.008). At 2-year follow-up, the two groups had become similar (p = 1.0). Elbow flexion For EF, there were no differences in age at presentation between the operative (6-8 months) and non-operative (5-8.5 months) groups (p = 0.98). Infants in the operative cohort had significantly worse initial function (p = 0.002). At 2-year follow-up, those two groups had become similar (p = 0.26). CONCLUSIONS Infants undergoing neurotization for Narakas grade 1 brachial plexus injury had similar long-term function to those who had improved and never required surgery. The preoperative exam findings were significantly different between the intervened and non-intervened groups, while the postoperative exam findings were not.

Abstract
Obstetric brachial plexus injuries (OBPP) are a relatively common stretch injury of the brachial plexus that occurs during delivery. Roughly 30 % of patients will not recover completely and will need a surgical repair. Two main treatment strategies have been used: primary surgery, consisting in exploring and reconstructing the affected portions of the brachial plexus within the first few months of the patient's life, and secondary procedures that include tendon or muscle transfers, osteotomies, and other orthopedic techniques. Secondary procedures can be done as the only surgical treatment of OBPP or after primary surgery, in order to minimize any residual deficits. Two things are crucial to achieving a good outcome: (1) the appropriate selection of patients, to separate those who will spontaneously recover from those who will recover only partially or not at all; and (2) a good surgical technique. The objective of the present review is to assess the published literature concerning certain controversial issues in OBPP, especially in terms of the true current state of primary and secondary procedures, their results, and the respective roles each plays in modern-day treatment of this complex pathology. Considerable published evidence compiled over decades of surgical experience favors primary nerve surgery as the initial therapeutic step in patients who do not recover spontaneously, followed by secondary surgeries for further functional improvement. As described in this review, the results of such treatment can greatly ameliorate function in affected limbs. For best results, multi-disciplinary teams should treat these patients.

Abstract
Cervical root avulsions are the worst pattern of injury in obstetrical brachial plexus injury (OBPI). The prognosis is poor and the treatment is mainly surgical with extraplexual neurotizations or muscle transfers. We present the outcomes of a technique performed in our institution to treat C5-C6 avulsion in obstetrical brachial plexus injury. This technique consists of a total ipsilateral C7 neurotization to the upper trunk. Ten babies with isolated C5-C6 root avulsion were operated on; we were able to review nine of them at over 12 months follow-up. The shoulder and the elbow function were assessed, as well as the Mallet Score. The mean follow-up was 9.2 years (SD 5.7). After a follow-up of 6 years, elbow flexion was restored with a range of motion ⩾130° and a motor function ⩾M3 in all patients. The average Mallet score was 18.1 (SD 1.2). This approach appears to be a viable alternative to extraplexual neurotizations for the treatment of C5-C6 nerve root avulsion.

Abstract
BACKGROUND The pathophysiology of elbow flexion contracture (EFC) in obstetrical brachial plexus injury (OBPI) is not established. In basic science models, neonatal denervation leads to impaired muscle growth. In clinical studies, diminished growth is correlated with extent of denervation, and improved with surgical repair. In EFC, the biceps are clinically short and round vs the contralateral size, termed the "Popeye muscle". The objective of this study was to determine if the biceps morphology (muscle belly and tendon length) in arms with EFC secondary to OBPI is different vs the contralateral. METHODS This is a retrospective matched-cohort study. Patients with unilateral EFC (>20°) secondary to OBPI were identified (median = 6.6 years, range = 4.7-16.8). A blinded radiologist used computed tomography to measure length of the biceps short head muscle belly, and tendon bilaterally using standardised anatomical landmarks. RESULTS Twelve patients were analyzed. The biceps muscle belly in the injured arm was shorter in all patients vs contralateral, mean difference = 3.6 cm (80%), p < 0.001. The biceps tendon in the injured arm was longer in all patients vs contralateral, mean difference = 1.13 cm (127%), p < 0.001. The total biceps length in the injured arm was shorter in all patients vs contralateral, mean difference = 2.5 cm (89%), p < 0.001. CONCLUSIONS This is the first human study confirming growth discrepancy of an elbow flexor in EFC. Distinct biceps morphology is demonstrated, with a significantly shorter muscle belly and overall length, but longer tendon vs normal. This is termed the "Popeye muscle" for its irregular morphology. Findings are consistent with impaired limb growth in denervation.

Abstract
Nerve transfers have gained popularity in the treatment of adult brachial plexus palsy; however, their role in the treatment of neonatal brachial plexus palsy (NBPP) remains unclear. Brachial plexus palsies in infants differ greatly from those in adults in the patterns of injury, potential for recovery, and influences of growth and development. This International Federation of Societies for Surgery of the Hand committee report on NBPP is based upon review of the current literature. We found no direct comparisons of nerve grafting to nerve transfer for primary reconstruction of NBPP. Although the results contained in individual reports that use each strategy for treatment of Erb palsy are similar, comparison of nerve transfer to nerve grafting is limited by inconsistencies in outcomes reported, by multiple confounding factors, and by small numbers of patients. Although the role of nerve transfers for primary reconstruction remains to be defined, nerve transfers have been found to be effective and useful in specific clinical circumstances including late presentation, isolated deficits, failed primary reconstruction, and multiple nerve root avulsions. In the case of NBPP more severe than Erb palsy, nerve transfers alone are inadequate to address all of the deficits and should only be considered as adjuncts if maximal re-innervation is to be achieved. Surgeons who commit to care of infants with NBPP need to avoid an over-reliance on nerve transfers and should also have the capability and inclination for brachial plexus exploration and nerve graft reconstruction.

Abstract
Brachial plexus birth palsy (BPBP) presents to the physician on a clinical spectrum, and may substantially impair the child. Potential interventions to improve function for the child with BPBP include physical therapy, microsurgical nerve reconstruction and nerve transfers, soft-tissue balancing and reconstruction with musculotendinous transfers, and osteotomies. Some interventions, such as nerve reconstruction, are best performed in infancy; others, such as muscle transfers and osteotomies, are performed to treat manifestations of this condition that appear later in childhood. Although controversy continues to exist regarding the natural history and surgical management of these patients, recent literature has improved our understanding of surgical indications, anticipated outcomes, and potential complications. On the basis of current evidence, we present here the recommendations for surgical intervention in the upper extremity of children with BPBP, and encourage early referral to a brachial plexus specialist to establish care.

Abstract
OBJECTIVE When root avulsions are detected in children suffering from obstetrical brachial plexus palsy (OBPP), neurotization procedures of different nerve trunks are commonly applied in primary brachial plexus repair, to connect distally the nerves of the upper limbs using healthy nerve structures. This article aims to outline our experience of neurotization procedures in OBPP, which involves nerve transfers in the event of delayed repair, when a primary repair has not occurred or has failed. In addition, we propose the opportunity for late repair, focusing on extending the time limit for nerve surgery beyond that which is usually recommended. Although, according to different authors, the time limit is still unclear, it is generally estimated that nerve repair should take place within the first months of life. In fact, microsurgical repair of OBPP is the technique of choice for young children with the condition who would otherwise have an unfavorable outcome. However, in certain cases the recovery process is not clearly defined so not all the patients are direct candidates for primary nerve surgery. METHODS In the period spanning January 2005 through January 2011, among a group of 105 patients suffering from OBPP, ranging from 1 month to 7 years of age, the authors have identified a group of 32 partially recovered patients. All these patients underwent selective neurotization surgery, which was performed in a period ranging from 5 months to 6.6 years of age. RESULTS Late neurotization of muscular groups achieved considerable functional recovery in these patients, who presented with reduced motor function during early childhood. The said patients, with the exception of five, would initially have avoided surgery because they had not met the criteria for nerve surgery. CONCLUSION We have concluded that the execution of late nerve surgical procedures can be effective in children affected by OBPP.

Abstract
BACKGROUND Nerve reconstruction strategies for restoration of elbow flexion and shoulder function in patients with neonatal brachial plexus palsy with neurotmesis of C5 and avulsion of C6 are not well defined and the outcomes are unclear. METHODS From 1990 to 2008, nerve surgery was performed in 421 patients with neonatal brachial plexus palsy. This study focused on thirty-four infants who had a neurotmetic lesion of C5 and avulsion or intraforaminal neurotmesis of C6, irrespective of C7. The C8 and T1 functions were intact. Intraplexal transfer of C6 to C5 with direct coaptation was preferred for restoration of elbow flexion. The suprascapular nerve was reconnected either by extra-intraplexal transfer of the accessory nerve or by grafting from C5 to restore shoulder function. Additional grafts were attached from C5 to the C5 contribution of the posterior division of the superior trunk when technically possible. RESULTS Transfer of either the C6 anterior root filaments or the entire C6 nerve to C5 was performed in seventeen patients (group A) with direct coaptation in fifteen of them. Grafting from C5 to the anterior division of the superior trunk was performed in the remaining seventeen infants (group B). An accessory-to-suprascapular nerve transfer was applied in twenty-nine infants. The suprascapular nerve was reconnected in five patients by grafting from C5. It was possible to attach one, two, or three additional grafts from C5 to the posterior division of the superior trunk in twenty-one patients. All infants had biceps muscle recovery to a Medical Research Council (MRC) grade of ≥4, twenty-two (65%) of the thirty-four patients obtained Mallet grade-IV abduction, and eleven (32%) of the thirty-four obtained Mallet grade-IV external rotation. CONCLUSIONS In patients with neonatal brachial plexus palsy who have neurotmesis of C5 and avulsion of C6, elbow flexion can be successfully restored with supraclavicular intraplexal reconstruction with use of C5 as the proximal outlet. However, shoulder function recovery following suprascapular nerve reinnervation and additional grafting from C5 to the posterior division of the superior trunk is less successful. LEVEL OF EVIDENCE Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Abstract
In obstetric brachial plexus lesions with avulsion injury, nerve grafting for biceps muscle re-innervation may not be possible owing to the unavailability of a proximal stump. In such cases, the intercostal nerves or medial pectoral nerve can serve as donor nerves in an end-to-end transfer to the musculocutaneous nerve. The present study reports the results of both techniques from a single institution in a consecutive series of 42 patients between 1995 and 2008. From 1995 to 2000 we always used the intercostal nerve transfer, and from 2001 to 2008 both techniques were used. Biceps muscle force ≥ Medical Research Council Grade 3 was achieved in 37 of 42 patients after a mean follow-up of 44 months. There was no statistical difference in the results in the medial pectoral nerve transfer group (n = 25) and the intercostal nerve transfer group (n = 17).

Abstract
Successful treatment of patients with neonatal brachial plexus palsy (NBPP) begins with a thorough understanding of the anatomy of the brachial plexus and of the pathophysiology of nerve injury via which the brachial plexus nerves stretched in the perinatal period manifest as a weak or paralyzed upper extremity in the newborn. NBPP can be classified by systems that can guide the prognosis and the management as these systems are based on the extent and severity of nerve injury, anatomy of nerve injury, and clinical presentation. Serial physical examinations, supplemented by a thorough maternal and perinatal history, are critical to the formulation of the treatment plan that relies upon occupational/physical therapy and rehabilitation management but may include nerve reconstruction and secondary musculoskeletal surgeries. Adjunctive imaging and electrodiagnostic studies provide additional information to guide prognosis and treatment. As research improves not only the technical aspects of NBPP treatment but also the ability to assess the activity and participation as well as body structure and function of NBPP patients, the functional outcomes for affected infants have an overall optimistic prognosis, with the majority recovering adequate functional use of the affected arm. Of importance are (i) early referral to interdisciplinary specialty clinics that can provide up-to-date advances in clinical care and (ii) increasing research/awareness of the psychosocial and patient-reported quality-of-life issues that surround the chronic disablement of NBPP.

Abstract
Introduction Transfer of a fascicle of the ulnar and/or median nerve to the musculocutaneous nerve in order to reinnervate the biceps and/or brachialis muscles has a high success rate and a low rate of complications in infants with upper (C5-C6) or extended upper (C5-C7) neonatal brachial plexus palsy. Step 1 Make the Incision Make a longitudinal incision along the midline of the middle third of the medial brachium. Step 2 Mobilize the Musculocutaneous Nerve The musculocutaneous nerve is typically found on the undersurface of the biceps muscle. Step 3 Mobilize the Median Nerve The median nerve runs along the neurovascular sheath medial to the brachial artery. Step 4 Mobilize the Ulnar Nerve The ulnar nerve lies posterior to the intermuscular septum. Step 5 Transfer the Donor Nerve to the Recipient Nerve Cut the donor fascicles distally and the recipient fascicles proximally to facilitate transfer. Step 6 Close the Wound Irrigate the wound, and close it in layers. Step 7 Postoperative Protocol Remove the bandages two weeks postoperatively, and encourage passive range-of-motion exercises. Results In our series, thirty-one patients underwent single or combined nerve fascicle transfer; twenty-seven (87%) obtained functional elbow flexion recovery (Active Movement Scale [AMS] score ≥ 6) while twenty-four (77%) obtained full elbow flexion recovery (AMS score = 7). Indications Contraindications Pitfalls & Challenges.

Abstract
BACKGROUND Nerve transfers using ulnar and/or median nerve fascicles to restore elbow flexion have been widely used following traumatic brachial plexus injury, but their utility following neonatal brachial plexus palsy remains unclear. The present multicenter study tested the hypothesis that these transfers can restore elbow flexion and supination in infants with neonatal brachial plexus palsy. METHODS We retrospectively reviewed the cases of thirty-one patients at three institutions who had undergone ulnar and/or median nerve fascicle transfer to the biceps and/or brachialis branches of the musculocutaneous nerve after neonatal brachial plexus palsy. The primary outcome measures were postoperative elbow flexion and supination as measured with the Active Movement Scale (AMS). Patients were followed for at least eighteen months postoperatively unless they obtained full elbow flexion or supination (AMS = 7) prior to eighteen months of follow-up. RESULTS Twenty-seven (87%) of the thirty-one patients obtained functional elbow flexion (AMS ≥ 6), and twenty-four (77%) obtained full recovery of elbow flexion against gravity (AMS = 7). Of the twenty-four patients for whom recovery of supination was recorded, five (21%) obtained functional recovery. Combined ulnar and median nerve fascicle transfers were performed in five patients and resulted in full recovery of elbow flexion against gravity and supination of AMS ≥ 5 for all five. Single-fascicle transfer was performed in twenty-six patients and resulted in functional flexion in 85% (twenty-two of twenty-six) and functional supination in 15% (three of twenty). Patients with nerve root avulsion were treated at a younger age (p < 0.01), had poorer preoperative elbow flexion (p < 0.01), and recovered greater supination (p < 0.01) compared with patients with dissociative recovery. Younger patients (p < 0.01) and patients with C5-C6 avulsion (p < 0.02) recovered the greatest supination. One patient sustained a transient anterior interosseous nerve palsy after median nerve fascicle transfer. CONCLUSIONS Ulnar and/or median nerve fascicle transfers were able to effectively restore functional elbow flexion in patients with nerve root avulsion, dissociative recovery, or late presentation following neonatal brachial plexus palsy. Recovery of supination was less, with greater success noted in younger patients with nerve root avulsion.

Abstract
Median nerve to biceps nerve transfer in the arm has been reported only in adults. The following paper reports on 10 cases of this transfer in obstetric brachial plexus palsy. All patients had upper palsy (ERb's or extended ERb's palsy) and presented to the author late (13-19 months of age) with poor or no recovery of elbow flexion. Following the nerve transfer, nine children recovered elbow flexion (a score of 6 in one child and a score of 7 in eight children by the Toronto scale). The remaining child did not recover elbow flexion.

Abstract
Peripheral nerve injuries are common conditions, with broad-ranging groups of symptoms depending on the severity and nerves involved. Although much knowledge exists on the mechanisms of injury and regeneration, reliable treatments that ensure full functional recovery are scarce. This review aims to summarize various ways these injuries are classified in light of decades of research on peripheral nerve injury and regeneration.

Abstract
OBJECTIVE To evaluate the factors influencing the results of ulnar nerve neurotization at the motor branch of the brachii biceps muscle, aiming at the restoration of elbow flexion in patients with brachial plexus injury. METHODS 19 patients, with 18 men and 1 woman, mean age 28.7 years. Eight patients had injury to roots C5-C6 and 11, to roots C5-C6-C7. The average time interval between injury and surgery was 7.5 months. Four patients had cervical fractures associated with brachial plexus injury. The postoperative follow-up was 15.7 months. RESULTS Eight patients recovered elbow flexion strength MRC grade 4; two, MRC grade 3 and nine, MRC <3. There was no impairment of the previous ulnar nerve function. CONCLUSION The surgical results of ulnar nerve neurotization at the motor branch of brachii biceps muscle are dependent on the interval between brachial plexus injury and surgical treatment, the presence of associated fractures of the cervical spine and occipital condyle, residual function of the C8-T1 roots after the injury and the involvement of the C7 root. Signs of reinnervation manifested up to 3 months after surgery showed better results in the long term. LEVEL OF EVIDENCE IV, Case Series.

Abstract
ABSTRACT
BACKGROUND:
In brachial plexus injuries, when there are no available roots to use as a source for graft reconstruction, nerve transfers emerge as an elective technique. For this purpose, transfer of an ulnar nerve fascicle to the biceps motor branch (Oberlin's procedure) is often used. Despite the high rate of good to excellent results in adults, this technique is seldom used in children.
OBJECTIVE:
To evaluate the efficacy and safety of Oberlin's procedure in the surgical treatment of brachial plexus birth palsy.
METHODS:
Striving to restore elbow flexion, we performed Oberlin's procedure in 17 infants with brachial plexus birth palsy. After follow-up of at least 19 months, primary outcomes were the strength of elbow flexion (modified British Medical Research Council Scale), hand function measured using Al-Qattan's Scale, and comparative x-rays of both hands to detect altered growth.
RESULTS:
Good to excellent results related to biceps contraction were obtained in 14 patients (82.3%) (3/MRC3, 11/MRC4). The preoperative Al-Qattan Scale score for the hand was maintained at final follow-up. Comparing the treated and normal limb, no difference was observed in hand development by x-ray.
CONCLUSION:
Oberlin's procedure is an effective and safe option for the surgical treatment of upper brachial plexus birth palsy.
