Thirty-six patients with avulsions of upper roots of the brachial plexus underwent transfer of a single fascicle from the ulnar nerve to the proximal motor branch of the biceps muscle to restore elbow flexion. The mean period of follow-up was 22 months. The average reinnervation time for the biceps muscle was 3.3 months. Thirty-four patients achieved biceps strength of Medical Research Council grade 3 or better. The operative results in the patients with C5, C6 avulsions were better than those with C5, C6, C7 avulsions. At the last follow-up examination, grip strength, pinch strength, moving two-point discrimination and the strength of flexion of the wrist on the affected side was not worse than before surgery in any patient.

Background: Partial ulnar nerve transfer to the biceps motor branch of the musculocutaneous nerve (Oberlin’s transfer) is a successful approach to restore elbow flexion in patients with upper brachial plexus injury (BPI). However, there is no report on more than 10 years subjective and objective outcomes. The purpose of this study was to clarify the long-term outcomes of Oberlin’s transfer based on the objective evaluation of elbow flexion strength and subjective functional evaluation of patients. Methods: Six patients with BPI who underwent Oberlin’s transfer were reviewed retrospectively by their medical records. The mean age at surgery was 29.5 years, and the mean follow-up duration was 13 years. The objective functional outcomes were evaluated by biceps muscle strength using the Medical Research Council (MRC) grade at preoperative, postoperative, and final follow-up. The patient-derived subjective functional outcomes were evaluated using the Quick Disability of the Arm, Shoulder, and Hand (QuickDASH) questionnaire at final follow-up. Results: All patients had MRC grade 0 (M0) or 1 (M1) elbow flexion strength before operation. Four patients gained M4 postoperatively and maintained or increased muscle strength at the final follow-up. One patient gained M3 postoperatively and at the final follow-up. Although one patient achieved M4 postoperatively, the strength was reduced to M2 due to additional disorder. The mean score of QuickDASH was 36.5 (range, 7–71). Patients were divided into two groups; three patients had lower scores and the other three patients had higher scores of QuickDASH. Conclusions: Oberlin’s transfer is effective in the restoration of elbow flexion and can maintain the strength for more than 10 years. Patients with upper BPI with restored elbow flexion strength and no complicated nerve disorders have over ten-year subjective satisfaction.

OBJECTIVEHuman acellular nerve allograft applications have increased in clinical practice, but no studies have quantified their influence on reconstruction outcomes for high-level, greater, and mixed nerves, especially the brachial plexus. The authors investigated the functional outcomes of human acellular nerve allograft reconstruction for nerve gaps in patients with brachial plexus injury (BPI) undergoing contralateral C7 (CC7) nerve root transfer to innervate the upper trunk, and they determined the independent predictors of recovery in shoulder abduction and elbow flexion.METHODSForty-five patients with partial or total BPI were eligible for this retrospective study after CC7 nerve root transfer to the upper trunk using human acellular nerve allografts. Deltoid and biceps muscle strength, degree of shoulder abduction and elbow flexion, Semmes-Weinstein monofilament test, and static two-point discrimination (S2PD) were examined according to the modified British Medical Research Council (mBMRC) scoring system, and disabilities of the arm, shoulder, and hand (DASH) were scored to establish the function of the affected upper limb. Meaningful recovery was defined as grades of M3–M5 or S3–S4 based on the scoring system. Subgroup analysis and univariate and multivariate logistic regression analyses were conducted to identify predictors of human acellular nerve allograft reconstruction.RESULTSThe mean follow-up duration and the mean human acellular nerve allograft length were 48.1 ± 10.1 months and 30.9 ± 5.9 mm, respectively. Deltoid and biceps muscle strength was grade M4 or M3 in 71.1% and 60.0% of patients. Patients in the following groups achieved a higher rate of meaningful recovery in deltoid and biceps strength, as well as lower DASH scores (p < 0.01): age < 20 years and age 20–29 years; allograft lengths ≤ 30 mm; and patients in whom the interval between injury and surgery was < 90 days. The meaningful sensory recovery rate was approximately 70% in the Semmes-Weinstein monofilament test and S2PD. According to univariate and multivariate logistic regression analyses, age, interval between injury and surgery, and allograft length significantly influenced functional outcomes.CONCLUSIONSHuman acellular nerve allografts offered safe reconstruction for 20- to 50-mm nerve gaps in procedures for CC7 nerve root transfer to repair the upper trunk after BPI. The group in which allograft lengths were ≤ 30 mm achieved better functional outcome than others, and the recommended length of allograft in this procedure was less than 30 mm. Age, interval between injury and surgery, and allograft length were independent predictors of functional outcomes after human acellular nerve allograft reconstruction.

Object In this study the authors evaluated the outcome in patients with brachial plexus injuries who underwent nerve transfers to the biceps and the brachialis branches of the musculocutaneous nerve. Methods The charts of eight patients who underwent an ulnar nerve fascicle transfer to the biceps branch of the musculocutaneous nerve and a separate transfer to the brachialis branch were retrospectively reviewed. Outcome was assessed using the Medical Research Council (MRC) grade to classify elbow flexion strength in conjunction with electromyography (EMG). The mean patient age was 26.4 years (range 16–45 years) and the mean time from injury to surgery was 3.8 months (range 2.5–7.5 months). Recovery of elbow flexion was MRC Grade 4 in five patients, and Grade 4+in three. Reinnervation of both the biceps and brachialis muscles was confirmed on EMG studies. Ulnar nerve function was not downgraded in any patient. Conclusions The use of nerve transfers to reinnervate the biceps and brachialis muscle provides excellent elbow flexion strength in patients with brachial plexus nerve injuries.

Object The authors report various techniques, and their results, after performing median and ulnar nerve transfers to reanimate the biceps muscle in C5–7 avulsion-related brachial plexus injuries (BPIs). Methods Forty-three adult patients with BPIs of the upper-middle plexus underwent reinnervation of the biceps muscle; neurotization of the musculocutaneous nerve was performed using fascicles from the ulnar nerve (39 cases) and the median nerve (four cases). The different techniques included sectioning, rerouting, and direct suturing of the entire musculocutaneous nerve (35 cases); direct reinnervation of the motor branches of the musculocutaneous nerve (three cases); and reinnervation using small grafts to the motor fascicles that enter the biceps muscle (five cases). Elbow flexion recovery ranged from M2 to M4+, according to the patient's age and the level of integrity of the hand. No surgery-related failure occurred. No significant difference in outcome was related to any of the technical variants. In patients younger than age 45 years and exhibiting a normal hand function a score of M4 or better was always achieved. On average, reinnervation occurred 6 months after surgery. There was no clinical evidence of donor nerve dysfunction. Conclusions When accurate selection criteria are met, the results after this type of neurotization have proved excellent.

Abstract Background Patients with lesions affecting C7 and C8 roots (in addition to C56) demonstrate loss of independent wrist dorsiflexion in addition to loss of shoulder abduction and elbow flexion. Traditionally, this deficit has been addressed using tendon transfers after useful function at the shoulder and elbow has been restored by primary nerve surgery. Confidence with nerve transfer techniques has prompted attempts to replace this method by incorporating procedures for wrist dorsiflexion in the primary operation itself. Aim The objective of this study was to report the results of pronator quadratus motor branch transfers to the extensor carpi radialis brevis motor branch to reconstruct wrist extension in C5–C8 root lesions of the brachial plexus. Patients and Methods Twenty-three patients, average age 30 years, with C5–8 root injuries underwent operations an average of 4.7 months after their accident. Extrinsic extension of the fingers and thumb was weak or absent in two cases while the remaining 18 patients could open their hand actively. The patients lacked independent wrist extension when they were examined with the fingers flexed as the compensatory action of the extrinsic finger extensors was removed. The average follow-up was 21 months postoperative with the minimal follow-up period was at least 12 months. Results Successful reinnervations of the extensor carpi radialis brevis (ECRB) were demonstrated in all patients. In 17 patients, wrist extension scored M4, and in 3 patients it scored M3. Conclusions The pronator quadratus (PQ) to ECRB nerve transfer in C5–C7 or C5–C8 brachial plexus injuries for independent wrist extension reconstruction gives consistently good results with minimal donor morbidity.

Object The clinical outcomes of patients with brachial plexus injuries who underwent double fascicular transfer (DFT) using fascicles from the median and ulnar nerves to reinnervate the biceps and brachialis muscles were evaluated. Methods The authors conducted a retrospective chart review of 29 patients with brachial plexus injuries that were treated with DFT for restoration of elbow flexion. All patients underwent pre- and postoperative clinical evaluation using the Medical Research Council grading system. Results The mean patient age was 37 years (range 17–68 years), and there was a mean follow-up of 19 ± 12 months (range 8–68 months). At the most recent follow-up, all but 1 patient (97%) had regained elbow flexion. Eight patients recovered Grade M5, 15 patients recovered Grade M4, and 4 patients recovered Grade M3 elbow flexion strength. There was no evidence of functional deficit in the donor nerve distributions. Conclusions Study results demonstrated the reliable restoration of M4–M5 elbow flexion following double fascicular transfer in patients with brachial plexus injuries.

Abstract OBJECTIVE To review the clinical outcomes in our patients who have undergone nerve transfer operations for brachial plexus reconstruction at the Louisiana State University (LSU) over a 10-year period. A secondary objective is to compare clinical outcomes in patients who had only nerve transfer operations as compared with patients whose nerve transfers were supplemented with direct repair of brachial plexus elements. METHODS Retrospective review of the medical records, imaging, and electrodiagnostic studies (electromyographic and nerve conduction studies) of patients with brachial plexus injuries who underwent nerve transfer operations at LSU over a period of 10 years. RESULTS A total of 81 patients were treated between 1995 to 2005 at the LSU Health Sciences Center; 7 of these patients were lost to follow-up, leaving 74 patients, with an average follow-up of 3.5 years, for review. We evaluated recovery of elbow flexion and shoulder abduction. Ninety percent of patients with medial pectoral to musculocutaneous nerve transfers recovered to LSU grade 2 (Medical Research Council grade 3), and 60% of those patients with intercostal to musculocutaneous nerve transfer regained similar strength in elbow flexion. Shoulder abduction recovery to LSU grade 2 (Medical Research Council grade 3) after spinal accessory to suprascapular and/or thoracodorsal to axillary nerve transfer, was 95% and 36%, respectively. There was a tendency for better motor recovery when nerve transfer operations were combined with direct repair of plexus elements. CONCLUSION Nerve transfers for repair of brachial plexus injuries result in excellent recovery of elbow and shoulder functions. Patients who had direct repair of brachial plexus elements in addition to nerve transfers tended to do better than those who had only nerve transfer operations.

We reviewed late functional results of a modified Steindler procedure in patients with obstetrical brachial plexus palsy and poor active elbow flexion. From 1982 to 2005, we reviewed final functional results and complications of 27 cases with flexion weakness of the elbow secondary to obstetrical brachial plexus injury, treated with a modified Steindler procedure. At the end of the follow-up, the mean active elbow flexion was 97° and the mean extensor lag was 10°. In the long-term follow-up, the modified Steindler procedure maintained good results in 67% of the cases in our series, and this percentage raised by 82% when the wrist extensor was present or restored before the Steindler procedure. There were poor results in 19% of the patients, but no major complications.

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.
