Abstract
PURPOSE Although re-innervation of the hand is considered a priority in the treatment of infants with complete brachial plexus injury, there is currently a paucity of publications investigating hand function outcomes following primary nerve reconstruction in infants with neonatal brachial plexus palsy (NBPP). This study therefore aimed to evaluate hand function outcomes in a series of patients with complete NBPP. METHODS This retrospective case series included all patients who underwent primary nerve surgery for complete neonatal brachial plexus palsy over an 8-year period. Outcomes were assessed using the Raimond Hand Scale. Classification of grade 3 or higher indicates a functional hand (assistance in bimanual activity). RESULTS Nineteen patients with a complete NBPP underwent primary nerve reconstruction at a mean age of 3.7 months. Periodic clinical evaluations were performed until at least 4 years of age. According to the Raimondi hand scale, one patient did not recover (grade 0), three patients attained grade 1, four grade 2, ten grade 3, and in one grade 4. Overall hand functional recovery was achieved in 57.8% (11/19) of patients. CONCLUSION Sufficient recovery of hand function to perform bimanual activity tasks in patients with complete NBPP lesions is possible and should be a priority in the surgical treatment of these infants.

Abstract
Injuries to the inferior trunk of the brachial plexus and its components can be debilitating. As such injuries are prioritized by surgeons during repair, an additional nerve transfer is considered herein. In the supine position, 13 adult cadavers (26 sides) underwent dissection of the nerve to subclavius and the proximal brachial plexus in the supraclavicular region. Once the nerve was located and isolated from origin to termination, measurements of its length and diameter were made. Next, the C8 and T1 roots and inferior trunk were identified. The distal end of the nerve to subclavius was transected and swung to these roots and the inferior trunk. Once the nerves to subclavius were transposed and in a tension-free manner, the length of excess nerve following being brought to each of these nerves was measured. A nerve to subclavius was identified on all sides. The nerve originated from the superior trunk and traveled anterior to the middle and inferior trunks on all sides. The mean diameter of the nerve to subclavius was 0.8 mm, and the mean length was 57 mm. After cutting the nerve to subclavius at its entrance into the subclavius muscle, the distal nerve could be transferred tension free to the inferior trunk of the brachial plexus and T1 ventral ramus on all sides. The distal nerve to subclavius reached the T1 ventral ramus with an average of 18 mm of additional length and to the C8 ventral ramus with an average of 19 mm. The nerve also could be transferred to the inferior trunk of the brachial plexus with an average of 20 mm of additional length. The nerve to subclavius was found to have approximately 3000 axons. To our knowledge, use of the nerve to subclavius has previously not been used for nerve transfer procedures. Based on our cadaveric study, this often-overlooked nerve can be easily transposed to other regional nerves such as the inferior trunk of the brachial plexus.

Long-Term Results of Microsurgical Brachial Plexus Reconstruction in Late-Presenting Cases of Brachial Plexus Birth Injury. J Hand Surg Am 2023; 48:126-133. [PMID: 36539318 DOI: 10.1016/j.jhsa.2022.11.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/24/2022] [Revised: 10/22/2022] [Accepted: 11/09/2022] [Indexed: 12/23/2022]
Abstract
PURPOSE The role of primary surgery in delayed presenting cases of brachial plexus birth injury is still debated. The purpose of this study was to evaluate the results of brachial plexus reconstruction performed at the age of ≥12 months. METHODS Twenty-nine cases were included. Five cases had upper (C5-6) palsy, 4 had upper/middle (C5-7), and 20 had total (C5-8 and T1) palsy. RESULTS The age at the time of primary surgery was an average of 15.6 months. The brachial plexus was formally explored and neurolysis, grafting, and neurotization were used in different combinations. Exploration revealed that 27% of the roots were avulsed and 32% were ruptured. The follow-up was an average of 7.9 years. Generally, the best functional recovery was elbow flexion followed by shoulder external rotation. Satisfactory shoulder abduction (≥6 on the Toronto Active Movement Scale [TAMS]) was achieved in 31% of cases. The abduction range was an average of 79° ± 35°; 50° in upper palsy, 103° in upper/middle palsy, and 82° in total palsy. Shoulder external rotation ≥6 on the TAMS was achieved in 62% of cases. External rotation range was an average of 58° ± 29°; 78° in upper palsy, 68° in upper/middle palsy, and 52° in total palsy. Elbow flexion and extension of ≥6 on the TAMS were achieved in 69% and 58% of cases, respectively. Wrist flexion and finger flexion of ≥6 on the TAMS were achieved in 35% and 12.5%, whereas wrist and finger extension of >6 on the TAMS were achieved in 25% and 4% of cases, respectively. CONCLUSION In the delayed presentation of brachial plexus birth injury, brachial plexus reconstruction results in good functional recovery of elbow flexion and shoulder external rotation but modest functional recovery of finger flexion and wrist extension. The rate of functional recovery of the elbow flexion was similar following nerve grafting and transfer. Nerve transfer for shoulder external rotation should be considered even in infants with available roots for grafting. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic IV.

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.

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
PURPOSE Hand function outcomes of primary nerve reconstruction for total brachial plexus birth injury (BPBI) are confounded by nerve roots left in continuity, inclusion of secondary procedures, and no assessment of the ability to perform activities of daily living. The purpose of this study was to evaluate the long-term hand function outcomes in a cohort of patients with a complete BPBI who had no nerve root in continuity prior to primary nerve reconstruction targeting the lower trunk. METHODS This single-center retrospective case series of complete BPBI included patients who underwent primary nerve reconstruction. The outcomes were assessed using the active movement scale (AMS) and brachial plexus outcome measure preoperatively and at the age of 4 and 8 years. RESULTS Fifty patients with a complete BPBI, of whom 82% (41/50) had an avulsion of C8-T1, underwent primary nerve reconstruction at a mean age of 4.1 months. Compared with the preoperative AMS scores, a statistically significant increase of AMS scores was observed at 4 and 8 years of age for all movements except forearm pronation. Between 4 and 8 years of age, there was a statistically significant improvement of external rotation of the shoulder and elbow flexion as well as diminution of thumb flexion. In the brachial plexus outcome measure assessment, there were 83% (24/29) at 4 years and 81% (21/26) at 8 years who had sufficient functional movement to perform wrist, finger, and thumb activities. CONCLUSIONS Functional hand outcome was restored to sufficiently perform bimanual activity tasks in 81% (21/26) of patients with a complete BPBI at 8 years of age. This affirmed that primary nerve reconstruction reinnervating the lower trunk can result in a functional extremity. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic IV.

Abstract
BACKGROUND Shoulder release and tendon transfer is frequently performed to address persistent weakness from neonatal brachial plexus palsy. Although postoperative improvements in motion are well described, associated deficits are poorly documented, and functional assessments are lacking. Loss of ability to reach midline can occur with surgery and may result in impairment. The purpose of this study was to comprehensively assess the gains, losses, functional changes, and patient-reported outcome associated with the authors' surgical approach. METHODS Consecutive patients undergoing surgery with 2-year follow-up were included (n = 30). Prospectively recorded assessments by therapists were reviewed. Changes were assessed by t test and Wilcoxon rank sum (p < 0.05). RESULTS Active external rotation and abduction improved and internal rotation diminished. Aggregate modified Mallet score increased with improvements in all subscales, except that hand to spine was unchanged and hand to belly decreased. Functional assessment using the Brachial Plexus Outcome Measure revealed an increase of aggregate score, with no decline in any subscales. Improvements were in hand to back of head, forward overhead reach, holds plate with palm up, opening large container, and strings bead. Aggregate patient self-report of appearance and function increased (from 18 to 23). Loss of ability to reach midline occurred in three patients (10 percent) who had extended Erb or total palsy and preoperative limitations of internal rotation. CONCLUSIONS Secondary reconstruction rebalances shoulder motion by increasing external rotation and abduction and reducing internal rotation. In this study, a conservative surgical approach results in overall improvement in task-based abilities and self-reported outcomes and preservation of internal rotation within a functional range.

Abstract
Botulinum neurotoxin A (BTX-A) intervention has long-term benefits for children with obstetric brachial plexus palsy (OBPP). Although cortical plasticity has been widely studied, plasticity in white matter has not received as much attention. Here, six children with OBPP underwent functional magnetic resonance imaging (fMRI) and diffusion tensor imaging (DTI) before and 6 months after BTX-A treatment. Surface electromyography (EMG) was recorded. The aim was to investigate changes in the corticospinal tract (CST) as an example longitudinal observation of white matter plasticity. Deterministic fiber tracking with a Fiber Assignment by Continuous Tracking algorithm was used to reconstruct the CST. Fiber tracts passing through a region of interest (ROI) in the posterior limb of the internal capsule and a target ROI in the upper-limb representation of M1 (defined by task-related fMRI) were selected as the CST. Motor performances were improved while EMG showed no significant difference 6 months after the treatment. We observed a significant increase in mean fractional anisotropy and a significant decrease in fiber number after treatment. We analyzed the correlations between DTI metrics and clinical motor assessments. Although the correlation results were not statistically significant, they support the notion that BTX-A treatment causes white matter plasticity and has a positive long-term outcome. Peripheral deafferentation may lead to altered information flow, resulting in the positive adaptation of white matter. This study provides novel insight into cerebral plasticity following peripheral nerve regeneration and indicates that a combination of relatively non-invasive therapies can accelerate plasticity of sensorimotor circuits and promote functional recovery in OBPP.

Abstract
UNLABELLED Transfer of the contralateral C7 nerve for reconstruction of the brachial plexus in infants with obstetrical brachial plexus injury has rarely been reported. We developed a new endoscopy-assisted technique via the prevertebral (retroesophageal) route for the transfer of the contralateral C7 nerve in reconstruction of the brachial plexus. The reconstruction was performed in 20 infants (14 boys and six girls). Motor recovery was assessed using the Gilbert and Raimondi scales. The Narakas Sensory Grading System was used to evaluate hand sensation. The mean follow-up period was 45 months (SD 18.2). Of the 20 children, nine had contralateral C7 transfer to lower nerve roots, two had transfer to upper nerve roots and nine had transfer to both upper and lower roots. The postoperative shoulder and elbow functions were good or satisfactory according to the Gilbert classification in all children whose preoperative scores were poor. All patients with lower roots reconstruction (9) had satisfactory hand function. A total of 15 children had a Narakas score of S3. Our technique enables safe contralateral C7 transfer to the avulsed roots in severe obstetrical brachial plexus injury infants with a satisfactory functional recovery. LEVEL OF EVIDENCE Level IV.

Abstract
Free functional muscle transfer provides an option for functional restoration when nerve reconstruction and tendon transfers are not feasible. To ensure a successful outcome, many factors need to be optimized, including proper patient selection, timing of intervention, donor muscle and motor nerve selection, optimal microneurovascular technique and tension setting, proper postoperative management, and appropriate rehabilitation. Functional outcomes of various applications to the upper extremity and the authors' algorithm for the use of free functional muscle transfer are also included in this article.

Abstract
BACKGROUND The aim of this study was to evaluate the results achieved using various surgical techniques in patients with partial and total obstetrical brachial plexus palsy. METHODS From 2000 to 2013, 33 patients with obstetrical brachial plexus injury underwent surgery. Twenty had follow-up periods greater than 24 months and met the criteria for inclusion in the study. All patients were evaluated using the Active Movement Scale. RESULTS The outcomes of different nerve reconstructive procedures including nerve transfers, nerve grafting after neuroma resection and end-to-side neurorrhaphy are presented. The overall success rate in upper plexus birth injury was 80 % in shoulder abduction, 50 % in external rotation and 81.8 % in elbow flexion with median follow-ups of 36 months. Success rate in complete paralysis was 87 % in finger and thumb flexion, 87 % in shoulder abduction and 75 % in elbow flexion; the median follow-up was 46 months. Useful reanimation of the hand was obtained in both patients who underwent end-to-side neurotization. CONCLUSION Improved function can be obtained in infants with obstetrical brachial plexus injury with early surgical reconstruction.

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
BACKGROUND Obstetric brachial plexus paralysis (OBPP) has been associated with shoulder deformities, scapular growth, and shoulder function impairment. The absence of balanced muscular forces acting on the scapula has been considered responsible for scapula dysplasia and impaired growth as compared with the normal side. Scapula growth impairment may also lead to shoulder and upper extremity dysfunction. This study aims at showing the association of primary nerve reconstruction with the restoration of scapular bone growth potential. METHODS This is a retrospective review of 73 patients with OBPP who underwent primary shoulder reconstruction. Patients were categorized for assessment and analysis into group A, global paralysis; group B, Erb's palsy; and group C, Erb's palsy with C7 root involvement. Scapular posteroanterior and lateral X-rays were obtained in which four scapula dimensions were manually measured. The growth discrepancy depending on the applied treatment was investigated. RESULTS The highest improvement was noted in scapular height in the Erb's palsy group who underwent simultaneous neurotization of the suprascapular and axillary nerves. The oblique axis was more improved in the Erb's palsy group while both big and small widths were more improved in the Erb's palsy with C7 root involvement group in patients who underwent concomitant neurotization of the suprascapular and the axillary nerves. Functional improvement correlated positively with growth improvement in all groups and scapular dimensions. CONCLUSION Scapula growth and shoulder function improvement were higher in patients with Erb's palsy. Simultaneous axillary and suprascapular nerve neurotization provided the best outcome in both functional and growth restoration.

Abstract
OBJECT In Erb palsy, the C-7 spinal nerve has been found to be more subject to avulsion than the C-5 and C-6 spinal nerves. This study investigated the morphological and biomechanical characteristics of the semiconic posterosuperior ligaments (SPLs) at the C-5, C-6, and C-7 spinal nerves in neonates. METHODS Twenty-four brachial plexuses from 12 fresh neonate cadavers were used in this study. In 12 brachial plexuses from 6 cadavers, the following studies were performed with respect to the SPLs at the C-5, C-6, and C-7 spinal nerves: gross observation of morphological and histological characteristics; measurement of length, thickness, and width; and a semiquantitative analysis of collagen. In the other 6 cadavers, biomechanical tension testing was performed bilaterally on the C5-7 SPLs to assess the tensile strength of the ligaments. RESULTS The C5-7 spinal nerves are fixed to the transverse process through the SPL, a structure not observed at the C-8 and T-1 spinal nerves. Except for the width of the SPL insertion on the spinal nerve, which was found to increase gradually from C-5 to C-7, there was no statistically significant difference in the dimensions of the C-5, C-6, and C-7 SPLs. The sectional area percentage of collagen was 51% ± 10% in SPLs for C-5, 51% ± 11% for C-6, and 41% ± 10% for C-7; and this percentage was significantly lower in SPLs for C-7 than for C-5 or C-6 (1-way ANOVA, F = 4.3, p = 0.02; Tukey honestly significant difference test, p = 0.04 and 0.04, respectively). Sharpey fibers were observed at the transverse process origin of the SPL at C-5 and C-6 but not at C-7. Biomechanical tension testing showed that the mean failure load was 6.6 ± 0.9 N for the C-5 SPL, 6.4 ± 1.0 N for the C-6 SPL, and 5.4 ± 0.9 N for the C-7 SPL, and the failure load was significantly lower in SPLs at C-7 than in those at C-5 or C-6 (1-way ANOVA, F = 5.1, p = 0.01; Tukey honestly significant difference, p = 0.01 and 0.048, respectively). Nine of 12 C-7 SPLs failed at their origin from the transverse process, while only 4 of 12 C-5 SPLs and 3 of 12 C-6 SPLs failed at the origin site. CONCLUSIONS These findings suggest that the lower density of collagen and absence of Sharpey fibers decrease the biomechanical properties of the C-7 SPL, and this may account for the higher frequency of avulsion of the C-7 spinal nerve (in comparison with the C-5 or C-6 nerve) in Erb palsy.

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
Contralateral C7 transfer is used rarely in infants with obstetrical brachial plexus palsy (OBPP). We aimed to determine the efficacy of contralateral C7 transfer to two different recipient nerves in infants with OBPP. Between 2001 and 2005, 9 infants with brachial plexus root avulsions underwent nerve reconstruction using a modified C7 neurotization technique. In this procedure, the contralateral C7 root was transferred to both the musculocutaneous nerve and the median nerve on the affected side. The strength of the biceps muscles increased to M3 or M4 in 7 patients and to M2 in 2 patients. The median nerve transfers led to regained motor function and strength of wrist and finger flexors with improvement to M3 or M4 in 5 patients. All patients showed notable gains of sensory function. Contralateral C7 transfer to two different recipient nerves is a feasible and efficient approach in infants with OBPP.

Complete obstetric brachial plexus palsy: surgical improvement to recover a functional hand. J Child Orthop 2009; 3:101-8.

Abstract
OBJECTIVE Complete obstetrical brachial plexus palsy remains a difficult situation for the child and his/her family. The quality of spontaneous reinnervation is rarely good and always leads to a non-sensitive and non-functional hand, even if abduction of the shoulder and elbow flexion do spontaneously recover. The aim of this study was to assess the results from nerve reconstruction in cases of complete palsy and to demonstrate the effect of a change in surgical technique on the outcome of hand function. METHODS Thirty pediatric patients with complete obstetric brachial plexus palsy were operated on in our department between 1987 and 2003. Twenty-five of these patients were clinically reviewed and evaluated by a physiotherapist and a surgeon (not the surgeon who performed the surgery). Functional assessment was based on the Gilbert shoulder score, the Gilbert-Raimondi score for elbow function and the Raimondi hand score. All children underwent a nerve reconstruction as graft and/or intra- or extra-plexual neurotization. Our neural surgical strategy changed between 1995 and 1996 to one that addresses the function of the hand and the wrist. A secondary surgical intervention was required in 18 cases. The most frequent procedures were a radial rotation osteotomy and a tendon transfer restoring wrist extension. RESULTS Mean follow-up was 7 years and 10 months. Among children operated on with the first surgical strategy-the pre-1995-1996 period-hand function was good in three cases, satisfactory in four cases and unsatisfactory in one case. Among children for whom the second surgical strategy was used-1995-1996 and later-hand function was good or very good in eight cases, satisfactory in four cases and unsatisfactory in two cases. When the 25 patients were assessed for shoulder function, the functional result was good or very good in 12 cases, satisfactory in seven cases and unsatisfactory in six cases. In terms of elbow function, the results were good or very good in 14 cases, satisfactory in eight cases and unsatisfactory in three cases. All hands recovered sensation to a certain degree. CONCLUSION The surgical results are encouraging in terms of shoulder and elbow function, but not as good for hand function. With the change in neural surgical strategy in 1995-1996, when more focus was placed on the hand (second surgical strategy), the results on hand function improved relative to those obtained with the first surgical strategy. It must also be noted that hand recovery requires more time, which may partially explain why functional results are not as good for the hand as for the shoulder and elbow. These results demonstrate that early surgical exploration is useful in complete obstetrical brachial plexus palsies and that there is a need for neural reconstruction of the lower trunk.
