We designed multiple nerve transfers in one surgery to restore active pick-up function in patients with total brachial plexus avulsion injuries. Forty patients with total brachial plexus avulsion injuries first underwent multiple nerve transfers. These included transfer of the accessory nerve onto the suprascapular nerve to recover shoulder abduction, contralateral C7 nerve onto the lower trunk via the modified prespinal route with direct coaptation to restore lower trunk function and onto the musculocutaneous nerve with interpositional bridging by medial antebrachial cutaneous nerve arising from lower trunk to restore elbow flexion, and the phrenic nerve onto the posterior division of lower trunk to recover elbow and finger extension. At least three years after surgery, the patients who had a meaningful recovery were selected to perform secondary reconstruction to restore active pick-up function. Active pick-up function was successfully restored in ten patients after they underwent multiple nerve transfers combined with additional secondary functional hand reconstructions. Level of evidence: IV

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.

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.

Stretch injuries of the C5-C7 roots of the brachial plexus traditionally have been associated with palsies of shoulder abduction/external rotation, elbow flexion/extension, and wrist, thumb, and finger extension. Based on current myotome maps we hypothesized that, as far as motion is concerned, palsies involving C5-C6 and C5-C7 root injuries should be similar. In 38 patients with upper-type palsies of the brachial plexus, we examined for correlations between clinical findings and root injury level, as documented by CT tomomyeloscan. Contrary to commonly held beliefs, C5-C7 root injuries were not associated with loss of extension of the elbow, wrist, thumb, or fingers, but residual hand strength was much lower with C5-C7 vs C5-C6 lesions.

OBJECT Adult upper trunk brachial plexus injuries result in significant disability. Several surgical treatment strategies exist, including nerve grafting, nerve transfers, and a combination of both approaches. However, no existing data clearly indicate the most successful strategy for restoring elbow flexion and shoulder abduction in these patients. The authors reviewed the literature to compare outcomes of the three surgical repair techniques listed above to determine the optimal approach to traumatic injury to the upper brachial plexus in adults. METHODS Both PubMed and EMBASE databases were searched for English-language articles containing the MeSH topic “brachial plexus” in conjunction with the word “injury” or “trauma” in the title and “surgery” or “repair” as a MeSH subheading or in the title, excluding pediatric articles and those articles limited to avulsions. The search was also limited to articles published after 1990 and containing at least 10 operated cases involving upper brachial plexus injuries. The search was supplemented with articles obtained through the “Related Articles” feature on PubMed and the bibliographies of selected publications. From the articles was collected information on the operation performed, number of operated cases, mean subject ages, sex distribution, interval between injury and surgery, source of nerve transfers, mean duration of follow-up, year of publication, and percentage of operative success in terms of elbow flexion and shoulder abduction of the injured limb. The recovery of elbow flexion and shoulder abduction was separately analyzed. A subanalysis was also performed to assess the recovery of elbow flexion following various neurotization techniques. RESULTS As regards the restoration of elbow flexion, nerve grafting led to significantly better outcomes than either nerve transfer or the combined techniques (F = 4.71, p = 0.0097). However, separating the Oberlin procedure from other neurotization techniques revealed that the former was significantly more successful (F = 82.82, p < 0.001). Moreover, in comparing the Oberlin procedure to nerve grafting or combined procedures, again the former was significantly more successful than either of the latter two approaches (F = 53.14; p < 0.001). In the restoration of shoulder abduction, nerve transfer was significantly more successful than the combined procedure (p = 0.046), which in turn was significantly better than nerve grafting procedures (F = 5.53, p = 0.0044). CONCLUSIONS According to data in this study, in upper trunk brachial plexus injuries in adults, the Oberlin procedure and nerve transfers are the more successful approaches to restore elbow flexion and shoulder abduction, respectively, compared with nerve grafting or combined techniques. A prospective, randomized controlled trial would be necessary to fully elucidate differences in outcome among the various surgical approaches.

This prospective study was carried out to assess motor and sensory recovery after contralateral C7 root to median nerve neurotization in brachial plexus injuries with total root avulsions. The survey was carried out from 1993 to 1995 and the patients were followed up for at least 3 years. There were 96 male patients with ages ranging from 13 to 48 years. All had a unilateral brachial plexus injury with avulsion of all roots. This was confirmed by clinical assessment and exploration. The anterior part of the contralateral C7 root was used for neurotization via a reversed pedicular ulnar nerve graft and the proximal end of the graft was connected to the median nerve. Furthermore, phrenic nerve to suprascapular nerve and spinal accessory nerve (via a sural nerve graft) to musculocutaneous nerve neurotizations were also carried out to obtain shoulder abduction and elbow flexion. At the 3 year follow-up, most patients had encouraging recovery of sensory function in the hand but motor function of the forearm and hand muscles was rather poor. Acceptable motor function was found in only 50 to 60% of the patients who were younger than 18 years.

Background and objectivesIpsilateral phrenic nerve palsy (PNP) is an undesirable side of conventional approaches to interscalene brachial plexus blocks. The purpose of this study was to demonstrate whether or not the phrenic nerve can be spared by dye when injected at the division of the upper trunk of the brachial plexus.MethodsUnder ultrasound guidance, 5 mL of radiolabeled dye was injected between the anterior and posterior division of the upper trunk in two fresh, cryopreserved cadavers. CT scan analysis, cadaveric dissection, and cryosectioning were performed to examine the spread of the injectate.ResultsWe found staining of the injectate over the entire upper trunk with its anterior and posterior divisions, the suprascapular nerve under the omohyoid muscle and the lateral pectoralis nerve, and the C5 and C6 roots. The middle trunk was partially stained. There was no evidence of dye staining of the lower trunk, anterior aspect of the anterior scalene muscle, or the phrenic nerve.ConclusionsOur study offers an anatomical basis for the possibility of providing shoulder analgesia and avoiding a PNP.

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.

Background: Conventional wisdom and the available literature demonstrate compromised outcomes following nerve reconstruction for traumatic brachial plexus palsy in the elderly. We present a 74-year-old male who was reconstructed with multiple nerve transfers for brachial plexus palsy after a ski accident. Methods: Triceps to axillary nerve transfer, spinal accessory to suprascapular nerve transfer, and ulnar to musculocutaneous nerve transfer were performed 16 weeks post injury. Results: At 11 years post-op, the patient could abduct to 65° and forward flex at M4 strength, limited only by painful glenohumeral arthritis. Elbow flexion was M5- at both the biceps and brachialis, and bulk and tone were nearly symmetrical with the opposite side. Eleven-year electrodiagnostic studies demonstrated reinnervation and improved motor unit recruitment all affected muscles. Conclusion: This case questions the widely held dogma that older patients who undergo brachial plexus reconstruction do poorly. Given the short reinnervation distance and optimal donor nerve health, nerve transfers may be an excellent option for healthy older patients with traumatic brachial plexus palsy.

Abstract Introduction Brachial plexus injuries are severe life-altering injuries. The surgical method to restore shoulder abduction in adult upper brachial plexus injuries involves the usage of nerve grafts and nerve transfers targeting the suprascapular and/or the axillary nerve. When the primary nerve surgery has been unsuccessful or recovery has been incomplete or with a late presentation, muscle transfer procedures are needed to provide or improve shoulder abduction. Levator scapulae to supraspinatus is a transfer to improve shoulder abduction in posttraumatic brachial plexus injuries. Material and Methods The study included 13 patients with the age ranging from 17 to 47 years with a mean age of 30 years. All these patients had preop shoulder abduction of Medical Research Council (MRC) grade ≤3. All had a minimum of MRC grade 4 of active elbow flexion. Eleven patients had primary surgery. Only patients with a minimum of 1 year postoperative follow-up were included. All 13 patients underwent levator scapulae transfer only. Results All patients had a stable shoulder postoperatively. The average increase in active shoulder abduction was from 6.15°(median: 0°) preoperatively to 61.92°(median: 60°), with an average gain in shoulder abduction of 49.61°(median: 50°). Conclusions Transfer of levator scapulae tendon to the supraspinatus is an option to improve shoulder abduction in posttraumatic brachial plexus. In conditions where supraspinatus alone is not functioning, levator scapulae is the best available transfer, considering its strength and maintaining the form of the shoulder unlike trapezius transfer. In patients with previous surgery where supraspinatus has recovered partially but not functionally significant, this tendon transfer can be considered for the augmentation of the existing shoulder abduction.

Background: The neural surgical options for reconstruction of elbow flexion in brachial plexus injuries depend on the availability of nerve donors. In upper-type avulsion injuries, the ulnar or median nerves, when intact, are reliable intra-plexal donor nerves for transfers to the biceps muscle. In complete avulsion injuries, donors are limited to extra-plexal sources, such as intercostal nerves (ICNs). Methods: We reviewed our results of ICN and partial distal nerve (ulnar or median) transfers for elbow flexion reconstruction in patients with brachial plexus avulsion injuries. The time taken for recovery of elbow flexion strength to M3 and the final motor outcome at 2 years were compared between both groups. Results: 38 patients were included in this study. 27 had ICN transfers to the musculocutaneous nerve (MCN), 8 had partial ulnar nerve transfers and 3 had partial median nerve transfers to the MCN's biceps motor branch. The mean time interval from injury to surgery was 3.6 months. Recovery of elbow flexion was observed earlier in the distal nerve transfer group (p < 0.05). Overall, success rates were higher in patients with distal nerve transfers (100%), compared to ICN transfers (63%) at 2 years (p = 0.018). Patients with distal nerve transfers achieved a higher final median strength of M4.0 [Interquartile range (IQR) 3.5–4.5], compared to M3.5 (IQR 2.0–4.0) in the ICN group (p = 0.031). In the subgroup of patients with upper-type brachial plexus injuries, there were no significant differences in motor outcomes between the ICN versus distal nerve transfers group. Conclusions: In our entire cohort, patients with distal nerve transfers had faster motor recovery and better elbow flexion power than patients with ICN transfers. In patients with partial brachial plexus injuries, outcomes of ICN transfers were not inferior to distal nerve transfers.
