Abstract Background The aim of this study was to compare postoperative elbow flexion outcomes in patients receiving functioning free muscle transplantation (FFMT) innervated by either intercostal nerve (ICN) or spinal accessory nerve (SAN) grafts. Methods A comprehensive systematic review on FFMT for brachial plexus reconstruction was conducted utilizing Medline/PubMed database. Analysis was designed to compare functional outcomes between (1) nerve graft type (ICN vs. SAN) and (2) different free muscle graft types to biceps tendon (gracilis vs. rectus femoris vs. latissimus dorsi). Results A total of 312 FFMTs innervated by ICNs (169) or the SAN (143) are featured in 10 case series. The mean patient age was 28 years. Patients had a mean injury to surgery time of 31.5 months and an average follow-up time of 39.1 months with 18 patients lost to follow-up. Muscles utilized included the gracilis (275), rectus femoris (28), and latissimus dorsi (8). After excluding those lost to follow-up or failures due to vascular compromise, the mean success rates of FFMTs innervated by ICNs and SAN were 64.1 and 65.4%, respectively. Conclusion This analysis did not identify any difference in outcomes between FFMTs via ICN grafts and those innervated by SAN grafts in restoring elbow flexion in traumatic brachial plexus injury patients.

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.

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 Introduction Elbow flexion is indispensable for both functioning and nonfunctioning hands. It is well perceived that restoration of elbow function is the first reconstructive priority in cases of brachial plexus injuries. The authors assessed the impact of associated distal humeral fractures on the functional outcome after unipolar latissimus dorsi transfer (ULDT) for restoration of elbow flexion in patients with residual brachial plexus palsy (BPP). Patients and Methods Twenty-three patients operated for restoring elbow flexion after residual post-traumatic BPP (with or without distal humeral fracture) by unipolar latissimus dorsi transfer (ULDT) were reviewed for a retrospective study. Patients were divided into two groups; associated distal humeral fracture group (HF-group; 10 patients) and non-associated distal humeral fracture group (NHF-group; 13 patients). Elbow flexion active range of motion (AROM), flexion deformity in addition to Mayo Elbow Performance Score (MEPS) were assessed. Results In both groups there were statistically better postoperative MEPS grading (p = 0.007, p = 0.001, respectively) and scoring with a mean of 81 ± 16.1 and 90 ± 4.6, respectively (p < 0.001). The mean postoperative elbow flexion AROM was statistically better in both groups. The mean supination AROM was better in NHF group (p = 0.057). Conclusion The use of ULDT in residual post-traumatic BPP is an efficient procedure in regaining functional flexion and supination. An associated distal humeral fracture does not significantly affect the final functional outcome. Level of Evidence Level IV.

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.

This study aimed to evaluate the effectiveness and safety of using the upper limb single-joint Hybrid Assistive Limb (upper limb HAL-SJ) during elbow flexion training following elbow flexor reconstruction for brachial plexus injury (BPI). We present the cases of two patients in whom the upper limb HAL-SJ was implemented 5 and 7 months postoperatively following elbow flexor reconstruction for BPI. They underwent elbow flexor reconstruction with intercostal nerve crossing-to-musculocutaneous nerve (ICN-MCN crossing) after BPI. Postoperative training using the upper limb HAL-SJ was started from the Medical Research Council (MRC) grade 1 elbow flexion power to MRC grade 3 once every week or every 2 weeks. Both patients could implement elbow training using the upper limb HAL-SJ even in MRC grade 1 of their elbow flexion power. Training with the upper limb HAL-SJ was performed safely and effectively in two patients with elbow flexor reconstruction with ICN crossing after BPI.
