Abstract
Background Neonatal Brachial plexus palsy is an injury during delivery that can lead to loss of motor function and limited range of motion in patients due to damage of nerves in the brachial plexus. This scoping review aims to explore types of procedures performed and assess outcomes of forearm and elbow secondary surgery in pediatric patients. Methods Searches of PubMed, Cochrane, Cumulative Index to Nursing and Allied Health Literature, Web of Sciences, and Scopus were completed to obtain studies describing surgical treatment of elbow and forearm in pediatric patients with neonatal Brachial plexus palsy. 865 abstracts and titles were screened by two independent reviewers resulting in 295 full text papers; after applying of inclusion and exclusion criteria 18 articles were included. The level of evidence of this study is level IV. Results Ten main procedures were performed to regain function of the forearm and elbow in neonatal brachial plexus birth palsy patients. Procedures had different aims, with supination contracture (6) and elbow flexion restoration (5) being the most prevalent. The variance between preoperative and postoperative soft tissue and bony procedures outcomes decreased and showed improvement with respect to the aim of each procedure category. For soft tissue procedures, a statistically significant increase was found between preoperative and postoperative values for active elbow flexion, passive supination, and active supination. For bony procedures, there was a statistically significant decrease between preoperative and postoperative values of passive and active supination. Conclusion Overall, all procedures completed in the assessed articles of this study were successful in their aim. Bony procedures, specifically osteotomies, were found to have a wider range of results, whereas soft tissue procedures were found to be more consistent and reproducible with respect to their outcomes. Bony and soft tissue procedures were found vary in their aims and outcomes. This study indicates the need for further research to augment knowledge about indications and long-term benefits to each procedure.

Abstract
PURPOSE In patients with late brachial plexus birth injuries, sequelae after acute flaccid myelitis, or chronic adult brachial plexus injury, donor nerves for functioning muscle transplantation are often scarce. We present the results of a potential strategy using the phrenic nerve with staged free gracilis transplantation for upper extremity reanimation in these scenarios. METHODS A retrospective review was performed on an institutional database of brachial plexus injury or patients with palsy. All patients underwent a staged reconstruction in which the ipsilateral phrenic nerve was extended by an autogenous nerve graft (PhNG), followed by free-functioning gracilis transplantation (PhNG-gracilis). RESULTS Nine patients (6 cases of late brachial plexus birth injuries, 2 of acute flaccid myelitis, and 1 of adult chronic brachial plexus injury) were included in this study. The median follow-up period following the PhNG-gracilis procedure was 27 months (range, 12-72 months). The goals of the staged PhNG and PhNG-gracilis were primarily finger extension or finger flexion. In some patients, the technique was used to improve both elbow and finger function, tunneling the muscle through the flexor compartment of the upper arm and under the mobile wad at the elbow. All patients exhibited improvement of muscle strength, including in finger extension (4 patients) from M0 to M2; finger flexion (3 patients) from M0 to M3; elbow extension (1 patient) from M0 to M2; and elbow flexion (1 patient) from M2 to M4. CONCLUSIONS A 2-stage PhNG-gracilis may restore or enhance the residual elbow and/or finger paralysis in chronic brachial plexus injuries. A minimum follow-up period of 3 years is recommended. This technique may remain useful as one of the last reconstructive options to increase power in patients with scarce donor nerves. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic V.

Abstract
BACKGROUND Restoring elbow function is challenging after late presenting brachial plexus birth injury (BPBI). Free functioning muscle transplantation (FFMT) using the gracilis muscle is a reliable procedure to restore elbow flexion in patients with impaired function after spontaneous recovery or failed surgical reconstruction. METHODS A retrospective review was performed on BPBI patients more than 2 years of age who received a FFMT between January 1993 and January 2018, with the aim of improving elbow flexion as the primary or secondary functional goal. Patients with preoperative elbow flexion Medical Research Council (MRC) grades less than 3 with more than or equal to 18 months of follow-up duration were included in the analysis. Patient demographic information and pre/postoperative clinical parameters including elbow flexion MRC scale, passive elbow range of motion, and complications were recorded. Surgical data including donor nerve choice, site of the FFMT tendon attachment, and necessity of concomitant procedures or reoperation were also analyzed. RESULTS Fifty-six FFMTs were performed for the primary (29 patients) or secondary (26 patients) objective of restoring elbow flexion. The mean age at the time of the procedure was 9.6 years (standard deviation [SD] = 6.29, R = 3-35). Mean follow-up was 7.9 years (SD = 5.2). Elbow flexion improved from a median MRC grade 2 to 4 after a FFMT (p < 0.05). Patients who had a FFMT to restore two functions had 86% lower elbow flexion MRC grades than those who had a FFMT to restore flexion only (p < 0.05). Patients less than 12 years old at the time of surgery had more complications, reoperations, and rates of a flexion contracture more than or equal to 30 degrees than those aged more than 12 years (p < 0.05). CONCLUSION FFMT is a reliable option for upper extremity reanimation. Patients aged less than 12 years old at the time of FFMT had significantly more complications, reoperations, and rates of postoperative elbow flexion contracture more than or equal to 30 degrees, but equivalent elbow flexion MRC grades.

Abstract
PURPOSE To analyze the outcome of the use of contralateral hemi-C7 for the restoration of hand function in patients with birth brachial plexus global palsy. METHODS From 2004 to 2017, 19 infants with Narakas types III and IV birth brachial plexus palsy underwent transfer of contralateral hemi-C7 (posterior division of the contralateral C7 root) to the lower trunk or medial cord on the affected side. All the patients were evaluated for shoulder function using the Gilbert and Mallet scores, elbow flexion using the modified Medical Research Council score for children, and hand function using the Raimondi score. After the surgery, the children were followed-up at 3-month intervals for the first year and 6-month intervals thereafter. Hand function achieving Raimondi scores of 3-5 was considered a useful outcome. RESULTS The patients were followed-up for a mean duration of 88 months, with a minimum of 35 and a maximum of 192 months of follow-up. All patients attained a Gilbert score of ≥3, whereas 9 patients attained a score of ≥4. Similarly, all patients attained a minimum aggregate Mallet score of 15, and 9 patients attained a score of ≥20. All patients attained a modified Medical Research Council score of ≥3, used for assessing elbow flexion. Useful hand function was attained in 73% (14/19) of the cases (a Raimondi score of ≥3). There was no clinically recorded deficit on the donor side. CONCLUSIONS Contralateral hemi-C7 transfer in infants with brachial plexus root avulsions helped regain useful hand function in 73% (14/19) of the children treated. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic IV.

Abstract
BACKGROUND Functional restoration of upper limb paralysis represents a major reconstructive challenge. Free functional muscle transfer (FFMT) enables reanimation in patients with a lack of local donor tissues or delayed presentation. This systematic review summarises the evidence for FFMT in the reconstruction of upper limb paralysis. METHODS A comprehensive search of MEDLINE and EMBASE was performed with a systematic review using methodology adapted from the Cochrane Handbook and the PRISMA statement. Data from included studies were compiled and narratively synthesised. Studies were assessed for risk of bias. RESULTS A total of 1155 records were screened, with 39 observational studies of 904 patients included. The most common aetiology was brachial plexus injury (736, 81.4%). Mean time from injury to intervention was 26 months. Restoration of elbow flexion was the commonest reconstructive goal. The most common donor muscle was gracilis (91.5%). Reported outcomes were heterogeneous with patient-reported outcome measures (PROMs) available in only 7 of 39 studies. Nearly half of FFMTs had a post-operative MRC grade of <4 and 18.1% had an MRC <3. Mean flap failure rate was 3.6% (range 0-10.5%). All studies were at high risk of bias. CONCLUSIONS FFMT may be an effective surgical intervention for upper limb paralysis; however, the current evidence has significant shortcomings. There is no consensus regarding outcome measures nor is it possible to identify prognostic factors for its effectiveness. This review highlights a need for improved study design with pre-operative assessment, standardisation in outcome reporting, and the use of PROMs to determine the effectiveness of FFMT in upper limb paralysis.

Abstract
Backround: Some children with obstetric brachial plexus palsy (OBPP) present later on with an ulnarly deviated wrist. The aim of this study was to present a retrospective analysis of a subgroup of OBPP children with ulnarly deviated wrists and to describe their morphologic wrist deformity in terms of clinical and radiological appearance. Methods: We present a retrospective analysis of the records of 27 children with an ulnarly deviated wrist as a consequence of OBPP. Radiographs of the affected wrist were performed when the ulnar deformity became clinically manifest and merited investigation, at a mean age of 15 (range: 6.5-27) years. Available clinical and radiological data were analyzed and categorized. Results: The ulnar-deviated position was associated with impaired active and passive pronosupination in all patients. Fifteen fixed supination deformities and 3 anterior radial head dislocations were noted clinically. Plain radiographs were completed in 24 patients and could be analyzed in 18, showing variations in ulnar variance (7 neutral, 7 ulna minus, and 4 ulna plus) along with 6 subluxations of the distal radioulnar joint (DRUJ). Of the patients treated surgically (n = 7), only the 2 patients treated with wrist fusion had an actual improvement in ulnar wrist deformity. Conclusion: Radiologically visible ulnar head hypoplasia, overgrowth of the distal ulna, or a shortened ulnar diaphysis and an incongruent DRUJ were present in all examined OBPP patients with a clinically evident ulnarly deviated wrists. The radiological findings highlight the morphologic adaptation behind this clinical condition and could allow further investigation into suitable treatment strategies.

Abstract
Ulnar deviation deformity of the wrist in patients with birth brachial plexus palsy is an important cosmetic concern among the patients and their relatives; especially in the patients who have recovered the basic limb functions. Though there is ample literature available regarding the management of the shoulder deformity there is paucity of literature regarding management of wrist ulnar deviation deformity. We report our experience with correction of this deformity in five cases with isolated ulnar deviation deformity without forearm rotational deformity or weakness of the wrist muscles. All the patients underwent extensor carpi ulnaris (ECU) to extensor carpi radialis longus (ECRL) tendon transfer. At a minimum of 18 months follow-up all the patients and their families were satisfied with the cosmetic appearance of the limb. Correction of the deformity improves the appearance of the limb, improves self-confidence of the child, and allows them to integrate well into the society. Interestingly, the patients expressed improvement in their grip strength and overall hand function after this surgery. The notable functions which improved were easy reach of the hand-to-mouth for feeding and easy handling of the things requiring bimanual activities. Although the main aim of this operation was to correct the appearance of the hand it was found to be also functionally useful by the patients and hence we are encouraged to report it for wider use. The results were maintained during the follow-up period of as long as 47 months.

Abstract
BACKGROUND In late obstetric brachial plexus palsy (OBPP), restoration of elbow and hand functions is a difficult challenge. The use of free functioning muscle transplantation in late OBPP was very scarcely reported. In this study, we present our experience on the use of free functioning gracilis transfer for restoration of elbow and hand functions in late cases of OBPP. PATIENTS AND METHODS Eighteen patients with late OBPP underwent free gracilis transfer for reconstruction of elbow and/or hand functions. The procedure was indicated when there was no evidence of reinnervation on EMG and in the absence of local donors. Average age at surgery was 102.5 months. Patients were evaluated using the British Medical Research Council (MRC) grading system and the Toronto Active Movement Scale. Hand function was evaluated by the Raimondi scoring system. RESULTS The average follow-up was 65.8 ± 41.7 months. Contraction of the transferred gracilis started at an average of 4.5 ± 1.03 months. Average range of elbow flexion significantly improved from 30 ± 55.7 to 104 ± 31.6 degrees (P <0.001). Elbow flexion power significantly increased with an average of 3.8 grades (P = 0.000147). Passive elbow range of motion significantly decreased from an average of 147 to 117 degrees (P = 0.003). Active finger flexion significantly improved from 5 ± 8.3 to 63 ± 39.9 degrees (P < 0.001). Finger flexion power significantly increased with an average 2.7 grades (P < 0.001). Only 17% achieved useful hand (grade 3) on Raimondi hand score. Triceps reconstruction resulted in an average of M4 power and 45 degrees elbow extension. CONCLUSION Free gracilis transfer may be a useful option for reconstruction of elbow and/or hand functions in late OBPP.

Abstract
Birth brachial plexus palsy (BBPP) is usually caused by plexus traction during difficult delivery. Although the possibility of complete recovery is relatively high, 5% to 25% of BBPP cases result in prolonged and persistent disability. In particular, muscle imbalance and co-contraction around the shoulder and elbow cause abnormal motor performance, osseous deformities, and joint contracture. Physical and occupational therapies have most commonly been used, but these conventional therapeutic strategies have often been inadequate, in managing the residual muscle imbalance and muscle co-contraction. Therefore, we attempted to improve the functional movements, by using botulinum toxin type A, to reduce the abnormal co-contraction of the antagonist muscles.

Abstract
Whenever a tendon or its bone insertion is disrupted or removed, existing surgical techniques provide a temporary connection or scaffolding to promote healing, but the interface of living to non-living materials soon breaks down under the stress of these applications, if it must bear the load more than acutely. Patients are thus disabled whose prostheses, defect size, or mere anatomy limit the availability or outcomes of such treatments. Our group developed the OrthoCoupler™ device to join skeletal muscle to prosthetic or natural structures without this interface breakdown. In this study, the goat knee extensor mechanism (quadriceps tendon, patella, and patellar tendon) was removed from the right hind limb in 16 goats. The device connected the quadriceps muscle to a stainless steel bone plate on the tibia. Mechanical testing and histology specimens were collected from each operated leg and contralateral unoperated control legs at 180 days. Maximum forces in the operated leg (vs. unoperated) were 1,400 ± 93 N (vs. 1,179 ± 61 N), linear stiffnesses were 33 ± 3 N/mm (vs. 37 ± 4 N/mm), and elongations at failure were 92.1 ± 5.3 mm (vs. 68.4 ± 3.8 mm; mean ± SEM). Higher maximum forces (p = 0.02) and elongations at failure (p=0.008) of legs with the device versus unoperated controls were significant; linear stiffnesses were not (p=0.3). We believe this technology will yield improved procedures for clinical challenges in orthopedic oncology, revision arthroplasty, tendon transfer, and tendon injury reconstruction.

Abstract
No permanent, reliable artificial tendon exists clinically. Our group developed the OrthoCoupler™ device as a versatile connector, fixed at one end to a muscle, and adaptable at the other end to inert implants such as prosthetic bones or to bone anchors. The objective of this study was to evaluate four configurations of the device to replace the extensor mechanism of the knee in goats. Within muscle, the four groups had: (A) needle-drawn uncoated bundles, (B) needle-drawn coated bundles, (C) barbed uncoated bundles, and (D) barbed coated bundles. The quadriceps tendon, patella, and patellar tendon were removed from the right hind limb in 24 goats. The four groups (n = 6 for each) were randomly assigned to connect the quadriceps muscle to the tibia (with a bone plate). Specimens were collected from each operated leg and contralateral unoperated controls both for mechanical testing and histology at 90 days post-surgery. In strength testing, maximum forces in the operated leg (vs. unoperated control) were 1,288 ± 123 N (vs. 1,387 ± 118 N) for group A, 1,323 ± 144 N (vs. 1,396 ± 779 N) for group B, 930 ± 125 N (vs. 1,337 ± 126 N) for group C, and 968 ± 109 N (vs. 1,528 ± 146 N) for group D (mean ± SEM). The strengths of the OrthoCoupler™ legs in the needled device groups were equivalent to unoperated controls (p = 0.6), while both barbed device groups had maximum forces significantly lower than their controls (p = 0.001). We believe this technology will yield improved procedures for clinical challenges in orthopaedic oncology, revision arthroplasty, tendon transfer, and tendon injury reconstruction.

Abstract
OBJECTIVES One of the unfortunate sequelae in obstetric brachial plexus palsy (OBPP) is upper limb length discrepancy. However, the influence of primary nerve reconstruction remains undetermined. In this study, the resultant discrepancy in children with OBPP who underwent primary reconstruction was analyzed in relation to the severity of the lesion, the timing of surgery, and the functional outcome following surgery. METHODS Fifty-four patients that met the inclusion criteria were included in this study. Preoperative and postoperative bilateral scanograms were obtained to document the effect of reinnervation on bone growth. The length of the humerus, ulna, third metacarpal, third proximal phalange, and total limb length were measured and the percentage between the affected and normal side were accessed. Correlations between all the measures of limb length and measures of active motion (i.e., three different classification systems) were performed. RESULTS Spearman's rank correlation coefficients revealed significant correlations between limb length discrepancies and nearly all measures of active upper extremity movement. The timing of surgery and the severity of the lesion significantly influenced the resultant limb length discrepancy. CONCLUSIONS The prevention of a non-acceptable upper limb discrepancy is fundamental for both the patient and family. The extent of the resultant discrepancy appeared to be strongly related to the time between injury and surgery, degree of severity, and the outcome of surgery. Patients with better functional recoveries of the affected upper extremities showed smaller differences in limb length.

Abstract
BACKGROUND In children with global obstetric brachial plexus palsy, prioritization should be first focused on hand reinnervation and then directed to shoulder and elbow function. In this study, the surgical strategy for restoration of hand function and the methods and outcomes are analyzed. METHODS Between 1979 and 2005, 59 patients (61 extremities) underwent reconstruction for hand reanimation. The mean follow-up was 7.7 years (range, 2 to 22 years). Of these, 16 cases underwent primary reconstruction alone, 35 underwent both primary and secondary procedures, and 10 late cases underwent palliative surgery. Hand function was evaluated with a modified Gilbert- Raimondi hand scale (grades 4 to 6 were considered useful outcomes). RESULTS Grade 4 or better functional recovery was observed in six of six cases (100 percent) that underwent primary reconstruction within the first 3 months of life. These patients did not require any secondary procedures. Multiple secondary procedures were necessitated to maximize the functional outcome in late cases or in patients with incomplete recovery following primary reconstruction. Overall, 46 of 61 cases (75.4 percent) achieved grade 4 or greater. The long-term results were better; 23 of 26 cases (88 percent) with a follow-up of more than 8 years achieved grade 4 or greater. CONCLUSIONS When primary reconstruction was performed within 3 months, functional return to the hand was the greatest and the need for palliative surgery was dramatically reduced. For older patients (>or=4 months), secondary procedures can significantly enhance hand function. The best results were seen when a combination of tendon transfers and free muscles transfers was performed.

Abstract
Inadequate elbow extension is a recognized sequela after obstetric brachial plexus injury because of muscle imbalance and adversely affects the ability to perform sufficiently most daily living activities. The various methods that have been used to correct this deformity do not offer a satisfactory outcome in the long term and show a tendency for gradual recurrence. We present a new technique of a closed gradual arthrodiatasis using a unilateral hinged elbow external fixator. The technique was applied in 10 patients with elbow flexion contracture as a sequela of brachial plexus birth palsy. Loss of elbow extension measured 55 degrees at average. With a mean device application of 8.8 weeks all patients gained full elbow extension. No major complications were noted. All patients were satisfied with the outcome. This novel technique (closed gradual arthrodiatasis of the elbow joint) has a definite role in the treatment of elbow flexion contracture in late cases of obstetric palsy, given the otherwise limited surgical options.

Abstract
A coupling mechanism that can permanently fix a forcefully contracting muscle to a bone anchor or any totally inert prosthesis would meet a serious need in orthopaedics. Our group developed the OrthoCoupler device to satisfy these demands. The objective of this study was to test OrthoCoupler's performance in vitro and in vivo in the goat semitendinosus tendon model. For in vitro evaluation, 40 samples were fatigue-tested, cycling at 10 load levels, n = 4 each. For in vivo evaluation, the semitendinosus tendon was removed bilaterally in eight goats. Left sides were reattached with an OrthoCoupler, and right sides were reattached using the Krackow stitch with #5 braided polyester sutures. Specimens were harvested 60 days postsurgery and assigned for biomechanics and histology. Fatigue strength of the devices in vitro was several times the contractile force of the semitendinosus muscle. The in vivo devices were built equivalent to two of the in vitro devices, providing an additional safety factor. In strength testing at necropsy, suture controls pulled out at 120.5 +/- 68.3 N, whereas each OrthoCoupler was still holding after the muscle tore, remotely, at 298 +/- 111.3 N (mean +/- SD) (p < 0.0003). Muscle tear strength was reached with the fiber-muscle composite produced in healing still soundly intact. This technology may be of value for orthopaedic challenges in oncology, revision arthroplasty, tendon transfer, and sports-injury reconstruction.

Abstract
We reviewed 42 consecutive children with a supination deformity of the forearm complicating severe birth lesions of the brachial plexus. The overall incidence over the study period was 6.9% (48 of 696). It was absent in those in Narakas group I (27.6) and occurred in 5.7% of group II (13 of 229), 9.6% of group III (11 of 114) and 23.4% of group IV (18 of 77). Concurrent deformities at the shoulder, elbow, wrist and hand were always present because of muscular imbalance from poor recovery of C5 and C7, inconsistent recovery of C8 and T1 and good recovery of C6. Early surgical correction improved the function of the upper limb and hand, but there was a tendency to recurrence. Pronation osteotomy placed the hand in a functional position, and increased the arc of rotation of the forearm. The supination deformity recurred in 40% (17 of 42) of those treated by pronation osteotomy alone, probably because of remodelling of the growing bone. Children should be followed up until skeletal maturity, and the parents counselled on the likelihood of multiple operations.

Abstract
In total brachial plexus palsy, fingers flexion restoration is a real challenge. Nerve surgery can generally restore shoulder abduction and elbow flexion. However, results of nerve grafts or nerve transfers are generally poor for hand function. As a matter of fact, the long distance between nerve sutures and terminal nerve branches in muscles decreases the rate of reinnervation. When finger flexion occurs, strength is generally weak and function remains fair. Therefore, we proposed a new technique to restore fingers flexion. The tensor fascia lata tendon is harvested and sutured between the biceps and flexor digitorum profundus (FDP) tendons. When elbow is flexed, the biceps muscle contraction pulls FDP tendons resulting in a partial but strong hand occlusion. This technique is an alternative to free muscle transfers or nerve surgery with reliable results.

Abstract
Active pronation is important for many activities of daily living. Loss of median nerve function including pronation is a rare sequela of humerus fracture. Tendon transfers to restore pronation are reserved for the obstetrical brachial plexus palsy patient. Transfer of expendable motor nerves is a treatment modality that can be used to restore active pronation. Nerve transfers are advantageous in that they do not require prolonged immobilization postoperatively, avoid operating within the zone of injury, reinnervate muscles in their native location prior to degeneration of the motor end plates, and result in minimal donor deficit. We report a case of lost median nerve function after a humerus fracture. Pronation was restored with transfer of the extensor carpi radialis brevis branch of the radial nerve to the pronator teres branch of the median nerve. Anterior interosseous nerve function was restored with transfer of the supinator branch to the anterior interosseous nerve. Clinically evident motor function was seen at 4 months postoperatively and continued to improve for the following 18 months. The patient has 4+/5 pronator teres, 4+/5 flexor pollicis longus, and 4-/5 index finger flexor digitorum profundus function. The transfer of the extensor carpi radialis brevis branch of the radial nerve to the pronator teres and supinator branch of the radial nerve to the anterior interosseous nerve is a novel, previously unreported method to restore extrinsic median nerve function.

Abstract
Birth brachial plexus injury usually affects the upper roots. In most cases, spontaneous reinnervation occurs in a variable degree. This aberrant reinnervation leaves characteristic deformities of the shoulder, elbow, forearm, wrist, and hand. Common sequelae are the internal rotation and adduction deformity of the shoulder, elbow flexion contractures, forearm supination deformity, and lack of wrist extension and finger flexion. Nowadays, the strategy in the management of obstetrical brachial plexus palsy focuses in close follow-up of the baby up to 3-6 months and if there are no signs of recovery, microsurgical repair is indicated. Nonetheless, palliative surgery consisting of an ensemble of secondary procedures is used to further improve the overall function of the upper extremity in patients who present late or fail to improve after primary management. These secondary procedures include transfers of free vascularized and neurotized muscles. We present and discuss our experience in treating early and/or late obstetrical palsies utilizing the above-mentioned microsurgical strategy and review the literature on the management of brachial plexus birth palsy.

Abstract
The double free-muscle transfer technique achieved a dramatic revolution in the treatment of total paralysis of the brachial plexus by providing universal prehensile function, although several requirements such as successful free-muscle transfers, stability of the proximal joints and prolonged postoperative rehabilitation are necessary for the success of this procedure. To obtain the best outcome of double free-muscle transfer, it is imperative to understand the key factors, viz. selection of the donor muscle, meticulous microsurgical technique, importance of proximal joint stability, selection of the kind of grip and postoperative rehabilitation. Double free-muscle transfer is not a simple microsurgical muscle transfer for finger movement, but a universal reconstructive procedure for total paralysis of the upper limb.

Abstract
BACKGROUND Strategies for management of infant obstetrical brachial plexus palsy remain controversial, including timing of surgery and treatment modalities. METHODS The senior author (Chuang) performed surgical explorations on 78 infant obstetrical brachial plexus palsy patients from 1992 to 1999. Sixty-eight patients underwent brachial plexus operation during the infant period (2 to 11 months), and 10 patients underwent surgery beyond the infant period. RESULTS For the ruptured upper and/or middle trunk injury (Erb's palsy), better shoulder and elbow function was observed in those who received numerous short grafts from C5 to the suprascapular and posterior division and from the C6 spinal nerve to the anterior division of the upper trunk. For the rupture injury associated with root avulsion (total palsy), nerve graft and transfer (intraplexus and extraplexus) provided a one-stage reconstruction for shoulder, elbow, and especially hand functions. The contralateral C7 or ipsilateral part of the ulnar nerve transfer was rarely used in infant obstetrical brachial plexus palsy, compared with adult brachial plexus injury. CONCLUSIONS The operative results proved that earlier timing of nerve surgery (within 3 months) is strongly indicated in patients who have total palsy, and only relatively indicated in patients with isolated rupture of the upper plexus.
