Abstract BACKGROUND AND IMPORTANCE: Restoration of elbow extension has not been considered of much importance regarding functional outcomes in brachial plexus surgery; however, the flexion of the elbow joint is only fully effective if the motion can be stabilized, what can be achieved solely if the triceps brachii is coactivated. To present a novel nerve transfer of a healthy motor fascicle from the ulnar nerve to the nerve of the long head of the triceps to restore the elbow extension function in brachial plexus injuries involving the upper and middle trunks. CLINICAL PRESENTATION: Case 1 is a 32-year-old man sustaining a right brachial extended upper plexus injury in a motorcycle accident 5 months before admission. The computed tomography myelogram demonstrated avulsion of the C5 and C6 roots. Case 2 is a 24-year-old man who sustained a C5-C7 injury to the left brachial plexus in a traffic accident 4 months before admission. Computed tomography myelogram demonstrated signs of C6 and C7 root avulsion. The technique included an incision at the medial border of the biceps, in the proximal third of the involved arm, followed by identification of the ulnar nerve, the radial nerve, and the branch to the long head of the triceps. The proximal stump of a motor fascicle from the ulnar nerve was sutured directly to the distal stump of the nerve of the long head of the triceps. Techniques to restore elbow flexion and shoulder abduction were applied in both cases. Triceps strength Medical Research Council M4 grade was obtained in both cases. CONCLUSION: The attempted nerve transfer was effective for restoration of elbow extension in primary brachial plexus surgery; however, it should be selected only for cases in which other reliable donor nerves were used to restore elbow flexion.

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.

We compared the outcomes of 23 partial ulnar nerve and 15 intercostal nerve transfers for elbow flexion reconstruction in patients with C56 or C567 brachial plexus injuries using manual muscle power, dynamometric measurements of elbow flexion strength and electromyography. The range of elbow flexion and muscle strength recovery to Grade 3 or 4 were comparable between the two groups. The patients with C567 injuries had significantly stronger eccentric contraction after the partial ulnar nerve transfer than after the intercostal nerve transfer ( p < 0.05). Electromyography of individual muscles demonstrated that the patients with partial ulnar nerve transfers were unable to voluntarily isolate biceps contraction and recruited forearm flexors and extensors. The patients after partial ulnar nerve transfer had significantly more activity of the forearm muscles during concentric elbow flexion than after intercostal nerve transfers ( p < 0.05). We conclude that partial ulnar nerve transfers were superior to intercostal nerve transfers when assessed quantitatively with the dynamometer to evaluate elbow flexion, although simultaneous recruitment of forearm muscles may have contributed to the increased elbow flexion strength in the patients with the partial ulnar nerve transfer.

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.

Intrinsic Muscles

In five cases of total root avulsion injury of brachial plexus, the thenar branch of the median nerve and the deep branch of the ulnar nerve were sutured to the branches of the femoral nerve during the procedure of intercostal, phrenic, accessory nerve transfer to the nerve trunks. The suture of the distal median or ulnar nerve in the hand to the femoral nerve was to maintain intrinsic muscles and prevent their atropy before arrival of nerve regeneration from the proximal end. The suture of the nerves was protected by wrapping it by abdominal flaps. The median and the ulnar nerve branches were separated from the femoral nerve when the NAP or SEP became detectable (about 1.5 years after the initial surgery). Good function of intrinsic muscles of the hand was observed in these five cases during the course of follow-up of the initial surgery, but the nerve recovery was not good after resuture of the median and the ulnar nerves. It was suggested from this preliminary clinical observation that suture of the distal median and ulnar nerves with the other nerves is effective in preservation of intrinsic muscle function, but recovery of intrinsic muscle function by resuture of the median and the ulnar nerves is not good.

Objective To present the functional outcomes of distal nerve transfer techniques for restoration of elbow flexion after upper brachial plexus injury. Method The files of 78 adult patients with C5, C6, ± C7 lesions were reviewed. The attempt to restore elbow flexion was made by intraplexus distal nerve transfers using a fascicle of the ulnar nerve (group A, n = 43), or a fascicle of the median nerve (group B, n = 16) or a combination of both (group C, n = 19). The result of the treatment was defined based on the British Medical Research Council grading system: muscle strength < M3 was considered a poor result. Results The global incidence of good/excellent results with these nerve transfers was 80.7%, and for different surgical techniques (groups A, B, C), it was 86%, 56.2% and 100% respectively. Patients submitted to ulnar nerve transfer or double transfer (ulnar + median fascicles transfer) had a better outcome than those submitted to median nerve transfer alone (p < 0.05). There was no significant difference between the outcome of ulnar transfer and double transfer. Conclusion In cases of traumatic injury of the upper brachial plexus, good and excelent results in the restoration of elbow flexion can be obtained using distal nerve transfers.

Finger Motion

Object In C7–T1 palsies of the brachial plexus, shoulder and elbow function are preserved, but finger motion is absent. Finger flexion has been reconstructed by tendon or nerve transfers. Finger extension has been restored ineffectively by attaching the extensor tendons to the distal aspect of the dorsal radius (termed tenodesis) or by tendon transfers. In these palsies, supinator muscle function is preserved, because innervation stems from the C-6 root. The feasibility of transferring supinator branches to the posterior interosseous nerve has been documented in a previous anatomical study. In this paper, the authors report the clinical results of supinator motor nerve transfer to the posterior interosseous nerve in 4 patients with a C7–T1 root lesion. Methods Four adult patients with C7–T1 root lesions underwent surgery between 5 and 7 months postinjury. The patients had preserved motion of the shoulder, elbow, and wrist, but they had complete palsy of finger motion. They underwent finger flexion reconstruction via transfer of the brachialis muscle, and finger and thumb extension were restored by transferring the supinator motor branches to the posterior interosseous nerve. This nerve transfer was performed through an incision over the proximal third of the radius. Dissection was carried out between the extensor carpi radialis brevis and the extensor digitorum communis. The patients were followed up as per regular protocol and underwent a final evaluation 12 months after surgery. To document the extent of recovery, the authors assessed the degree of active metacarpophalangeal joint extension of the long fingers. The thumb span was evaluated by measuring the distance between the thumb pulp and the lateral aspect of the index finger. Results Surgery to transfer the supinator motor branches to the posterior interosseous nerve was straightforward. Twelve months after surgery, all patients were capable of opening their hand and could fully extend their metacarpophalangeal joints. The distance of thumb abduction improved from 0 to 5 cm from the lateral aspect of the index finger. Conclusions Transferring supinator motor nerves directly to the posterior interosseous nerve is effective in at least partially restoring thumb and finger extension in patients with lower-type injuries of the brachial plexus.
