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.

The latissimus dorsi transfer and the Steindler flexorplasty were compared to restore elbow flexion in seven cases. All patients had sustained upper trunk brachial plexus injuries and were adults of productive age. Both operations were successful. The results showed that the latissimus dorsi transfer provides more powerful elbow flexion and a greater range of movement one year post-operatively. The criteria for selection of candidates for both operations are set out.

Background: Plate and screw fixation during the treatment of distal humeral fracture in adults is considered to be a gold standard that makes anatomic and articular reduction. Injury of the ulnar nerve is a common condition that can be found in pre-operative, intraoperative, and postoperative. Intraoperative anterior subcutaneous transposition is still a controversial issue. Objective: To understand the variation of distance of the ulnar nerve during elbow motion with the anatomical landmark of distal humeral bone and plate position after fixation. Materials and Methods: The authors have studied ten fresh adult cadavers, who underwent autopsy at the Department of Forensic Medicine of Srinakharinwirot University. Results: The results showed that in zone 2, the Center of the medial condyle was the position of the distal humeral bone with the most variation in position changing during elbow flexion/extension. In the sagittal plane (+2.56 to –4.58 mm), the mean difference equaled to 7.14 mm, while in the coronal plane (+1.70 to –5.14 mm), the mean difference equaled to 6.84 mm, with the highest percentage of irritation up to 70%. Furthermore, 14 cases of ulnar nerve subluxation were found in 20 studies (70%). Conclusion: From the present study, the Medial condyle was the landmark with the most irritation and position changing of ulnar nerve during elbow flexion. The incidence of ulnar subluxation occurred after in situ release for plate fixation was also found higher than in previous studies.

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.

Latissimus Dorsi Transfer

Background: Brachial plexus injuries are troubling for the patients socially, economically and emotionally. Elbow joint being a large and vital joint needs to be reanimated so that the patient can carry out his routine work and bring the hand to the mouth. Number of procedures have been defined but latissimus dorsi being a large muscle is the muscle of choice for transfer in cases who present late. Bipolar latissimus dorsi transfers have often been reported but unipolar latissimus dorsi transfer has also been described. Authors have studied the unipolar muscle transfer, it’s surgical technique and results.Methods: In this study 18 patients were studied for demographic data, pre- and post-operative flexion of the elbow and the MRC grade of the corresponding movements. Diagnostic work up in the form of nerve conduction velocity, electromyography and magnetic resonance imaging were carried out and evaluated for their significance in traumatic brachial plexus injuries.Results: In this study 13 patients had avulsion of the C5-6 roots on magnetic resonance imaging. The patients presented after a period of 128.83±56.76 days. Substantial time elapsed and ruled out primary brachial plexus reconstruction or nerve transfers. The average elbow flexion improved from 6.67±5.69 degrees (range: 0-20 degrees) to 86.94±12.38 degrees (range: 65-110 degrees) following unipolar latissimus dorsi transfer. 12 patients (66.67%) developed M4 or M4+ power.Conclusions: Unipolar latissimus dorsi muscle transfer is a reliable method and most of the patients develop adequate strength and satisfactory function at the elbow joint.

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.

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.

Shoulder External Rotation

This report describes the results of latissimus dorsi transfer for weakness of shoulder external rotation in 12 children with obstetric brachial plexus palsy. Selection criteria for the muscle transfer procedure included good passive external rotation of the shoulder, normal skeletal development of the shoulder joint, and adequate power of the deltoid. In addition to measuring the ranges of motion of joints before and after surgery, a modified Mallet grading system was utilized for the functional assessment of shoulder external rotation. At a mean follow-up of 4 years, two of the 12 children had recurrence of the shoulder deformity. In the remaining 10 children, the mean active external rotation was 30° (range, 20–60°), mean shoulder abduction was 140° (range, 90–170°), and all children had achieved a modified Mallet score of 4.

Background The purpose of this study was to prospectively compare clinical outcomes of reverse total shoulder arthroplasty (RTSA) combined with latissimus dorsi transfer by modified L’Episcopo (Group I) versus the greater tuberosity (Group II) in patients with lack of elevation and external rotation in the shoulder. Materials and methods Eighteen patients participated in the study. They were placed randomly into two groups of nine patients in each group. The results were evaluated prior to surgery and at the end follow-up. Results The average follow-up was 33.2 months. The mean ASES scores improved from 13 points to 79 in Group I and from 15 to 73 in Group II. The mean Constant shoulder scores improved from 19 to 66 in Group I and from 18 to 67 in Group II. Mean active elevation increased from 59° to 147° in Group I and from 58° to 148° in Group II. The mean external rotation scores increased from −43° to 7° in Group I and from −41° to 23° in Group II. Conclusion Comparing clinical outcomes and active elevation, there were no significant differences. The latissimus dorsi transfer to the greater tuberosity provided greater external rotation than did the modified L’Episcopo transfer.
