Abstract BACKGROUND AND IMPORTANCE: To report on the successful use of a platysma motor nerve transfer to the accessory nerve in a patient with concomitant trapezius and brachial plexus palsy. CLINICAL PRESENTATION: A 20-year-old man presented with total avulsion of the right brachial plexus combined with palsies of the accessory and phrenic nerve. The patient was operated on 4 months after his injury. The accessory nerve was repaired via direct transfer of the platysma motor branch. The contralateral C7 root was connected to the musculocutaneous nerve, and the hemihypoglossal nerve was grafted to the suprascapular nerve. Two intercostal nerves were attached to the triceps long head motor branch. CONCLUSION: Within 20 months of surgery, the patient regained full reinnervation of the upper trapezius muscle. Elbow flexion scored M3+, and 30° active shoulder abduction was observed. Triceps reinnervation was poor. Platysma motor branch transfer to the accessory nerve is a viable alternative to reinnervate the trapezius muscle.

Adult brachial plexus injury is a now a common problem due to high incidence of motorbike accidents. Among all types, C 5 and C6 (upper brachial plexus injury) is the most common. If the patient present within 6 months then nerve transfer is the preferred treatment. However, there are different options for nerve transfer and different approaches for surgery. Objectives: The objective of the study was to share our experience of nerve transfer close to target muscles in upper brachial plexus injury. Study Design: Quaisi experimental study. Setting: National Orthopaedic Hospital, Bahawalpur. Period: January 2015 to June 2018. Material & Methods: Total 32 patients were operated with isolated C5 and C6 injury. In all patients four nerve transfers were done. For shoulder abduction posterior approach was used and accessory to suprascapular nerve and one of motor branch of radial to axillary nerve were transferred. Modified Oberlin transfer was done for elbow flexion. Both shoulder abduction and elbow flexion was graded according to medical research council grading system. Results: After one year follow up more than 75% of the patients showed good to normal shoulder abduction and 87.50% showed good to normal elbow flexion. Residual Median nerve damage was noted only in two patients (6.25%). Conclusion: If there is no evidence of recovery up to three months early nerve transfer should be considered, ideal time is 3-6 months. Nerve transfer close to target muscle yields superior results. The shoulder stabilizers and abductors should ideally be innervated by double nerve transfer through posterior approach. Similarly double fascicular transfer (modified Oberlin) should be done for elbow flexion.

Abstract Objective: The accessory nerve is frequently used as a donor for nerve transfer in brachial plexus injuries. In currently available techniques, nerve identification and dissection is difficult because fat tissue, lymphatic vessels, and blood vessels surround the nerve. We propose a technique for location and dissection of the accessory nerve between the deep cervical fascia and the trapezius muscle. Methods: Twenty-eight patients with brachial plexus palsy had the accessory nerve surgically transplanted to the suprascapular nerve. To harvest the accessory nerve, the anterior border of the trapezius muscle was located 2 to 3 cm above the clavicle. The fascia over the trapezius muscle was incised and detached from the anterior surface of the muscle, initially, close to the clavicle, then proximally. The trapezius muscle was detached from the clavicle for 3 to 4 cm. The accessory nerve and its branches entering the trapezius muscle were identified. The accessory nerve was sectioned as distally as possible. To allow for accessory nerve mobilization, one or two proximal branches to the trapezius muscle were cut. The most proximal branch was always identified and preserved. A tunnel was created in the detached fascia, and the accessory nerve was passed through this tunnel to the brachial plexus. Results: In all of the cases, the accessory nerve was easily identified under direct vision, without the use of electric stimulation. Direct coaptation of the accessory nerve with the suprascapular nerve was possible in all patients. Conclusion: The technique proposed here for harvesting the accessory nerve for transfer made its identification and dissection easier.

The purpose of this study was to investigate the anatomical basis of intercostal nerve transfer to the suprascapular nerve and provide a case report. Thoracic walls of 30 embalmed human cadavers were used to investigate the anatomical feasibility for neurotization of the suprascapular nerve with intercostal nerves in brachial plexus root avulsions. We found that the 3rd and 4th intercostal nerves could be transferred to the suprascapular nerve without a nerve graft. Based on the anatomical study, the 3rd and 4th intercostal nerves were transferred to the suprascapular nerve via the deltopectoral approach in a 42-year-old man who had had C5-7 root avulsions and partial injury of C8, T1 of the right brachial plexus. Thirty-two months postoperatively, the patient gained 30° of shoulder abduction and 45° of external rotation. This procedure provided us with a reliable and convenient method for shoulder function reconstruction after brachial plexus root avulsion accompanied with spinal accessory nerve injury. It can also be used when the accessory nerve is intact but needs to be preserved for better shoulder stability or possible future trapezius transfer.

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.

AbstractIn irreparable C5, C6 spinal nerve and upper truncal injuries the proximal root stumps are not available for grafting, hence repair is based on nerve transfer or neurotization. Between Feb 2004 and May 2006, 23 patients with irreparable C5, C6 or upper truncal injuries of the Brachial Plexus underwent multiple nerve transfers to restore the shoulder and elbow functions. Most of them (16 patients) sustained injury following motor cycle accidents. The average denervation period was 5.3 months. Shoulder function was restored by transfer of distal part of spinal accessory nerve to suprascapular nerve, and transfer of radial nerve branch to long head of triceps to the anterior branch of axillary nerve. Elbow function was restored by transfers of ulnar and median nerve fascicles to the biceps and brachialis motor branches of musculocutaneous nerve. All patients recovered shoulder abduction and external rotation; 7 scored M4 and 16 scored M3. Range of abduction averaged 1230(range, 800-1700). Full elbow flexion was restored in all 23 patients; 15 scored M4 and 8 scored M3. Patients with excellent results could lift 5 kgs of weight. Selective nerve transfers close to the target muscle provide an early and good return of functions. There is negligible morbidity in donor nerves. These intraplexal transfers are suitable in all cases of upper brachial plexus injuries.

Nerve transfers Oberlin-type are currently used in upper brachial plexus lesions to recover elbow flexion. Is the regained active motion sufficient to resume heavy manual activities? Five adult patients (mean age 37 years) operated of a nerve transfer to recover elbow flexion (transfer of a motor fascicle of the ulnar nerve to the motor branch of the biceps; in three patients, additional transfer from the median to the motor nerve of the brachialis) were clinically and isokinetically evaluated, after a mean follow-up of 47 months. The median Constant-Murley score was 22/100, the DASH 56/100 and the MEPI 60/100. For isokinetic tests the most significant finding was a severe deficit of elbow strength, of about 80%. No patient was able to maintain an isometric contraction during sufficient time to evaluate fatigability. This preliminary study suggests that major functional impairments persist despite early recovery of elbow flexion. These results should be confirmed in a study on a larger group of patients.

OBJECTIVE Transfer of the spinal accessory nerve to the suprascapular nerve is a common procedure, performed to reestablish shoulder motion in patients with total brachial plexus palsy. However, the results of this procedure remain largely unknown. METHODS Over an 11-year period (2002–2012), 257 patients with total brachial plexus palsy were operated upon in the authors' department by a single surgeon and had the spinal accessory nerve transferred to the suprascapular nerve. Among these, 110 had adequate follow-up and were included in this study. Their average age was 26 years (SD 8.4 years), and the mean interval between their injury and surgery was 5.2 months (SD 2.4 months). Prior to 2005, the suprascapular and spinal accessory nerves were dissected through a classic supraclavicular L-shape incision (n = 29). Afterward (n = 81), the spinal accessory and suprascapular nerves were dissected via an oblique incision, extending from the point at which the plexus crossed the clavicle to the anterior border of the trapezius muscle. In 17 of these patients, because of clavicle fractures or dislocation, scapular fractures or retroclavicular scarring, the incision was extended by detaching the trapezius from the clavicle to expose the suprascapular nerve at the suprascapular fossa. In all patients, the brachial plexus was explored and elbow flexion reconstructed by root grafting (n = 95), root grafting and phrenic nerve transfer (n = 6), phrenic nerve transfer (n = 1), or third, fourth, and fifth intercostal nerve transfer. Postoperatively, patients were followed for an average of 40 months (SD 13.7 months). RESULTS Failed recovery, meaning less than 30° abduction, was observed in 10 (9%) of the 110 patients. The failure rate was 25% between 2002 and 2004, but dropped to 5% after the staged/extended approach was introduced. The mean overall range of abduction recovery was 58.5° (SD 26°). Comparing before and after distal suprascapular nerve exploration (2005–2012), the range of abduction recovery was 45° (SD 25.1°) versus 62° (SD 25.3°), respectively (p = 0.002). In patients who recovered at least 30° of abduction, recovery of elbow flexion to at least an M3 level of strength increased the range of abduction by an average of 13° (p = 0.01). Before the extended approach, 2 (7%) of 29 patients recovered active external rotation of 20° and 120°. With the staged/extended approach, 32 (40%) of 81 recovered some degree of active external rotation. In these patients, the average range of motion measured from the thorax was 87° (SD 40.6°). CONCLUSIONS In total palsies of the brachial plexus, using the spinal accessory nerve for transfer to the suprascapular nerve is reliable and provides some recovery of abduction for a large majority of patients. In a few patients, a more extensive approach to access the suprascapular nerve, including, if necessary, dissection in the suprascapular fossa, may enhance outcomes.

Abstract BACKGROUND: Stretch-induced spinal accessory nerve palsy has been considered extremely rare, with only a few cases reported. OBJECTIVE: In 357 patients with stretch lesions of the brachial plexus, we investigated the prevalence, course, and surgical treatment of accessory nerve palsy. METHODS: Accessory nerve palsy was ascertained when the patient was unable to shrug the ipsilateral shoulder. Patients underwent brachial plexus reconstruction between 6 and 8 months after trauma. To confirm paralysis, during surgery, the accessory nerve was stimulated electrically. RESULTS: Accessory nerve palsy occurred in 19 of the 327 patients (6%) with upper type or complete palsy of the brachial plexus. Proximal injuries of the accessory nerve accompanied by voice alteration and complete palsy of the sternocleidomastoid and trapezius muscle occurred in 2 patients. Proximal palsy without vocal alterations was observed in 6 patients. Palsy of the trapezius muscle with preservation of the sternocleidomastoid muscle occurred in 11 patients. All 7 patients who demonstrated muscle contractions upon electrical stimulation of the accessory nerve during surgery recovered completely. Patients with surgical reconstruction of the accessory nerve through grafting (n = 2) or repair by platysma motor nerve transfer (n = 2) recovered active shoulder shrugging within 36 months of surgery. Seven of the 8 patients without accessory nerve reconstruction recovered from their drop shoulder and head tilt, but remained unable to shrug. CONCLUSION: If intraoperative electrical stimulation produces contraction of the upper trapezius muscle, no repair is needed. In proximal injuries, the platysma motor branch should be transferred to the accessory nerve; whereas in paralysis distal to the sternocleidomastoid muscle, the accessory nerve should be explored and grafted.

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.
