Background Restoring elbow function is challenging after late presenting brachial plexus birth injury (BPBI). Free functioning muscle transplantation (FFMT) using the gracilis muscle is a reliable procedure to restore elbow flexion in patients with impaired function after spontaneous recovery or failed surgical reconstruction. Methods A retrospective review was performed on BPBI patients more than 2 years of age who received a FFMT between January 1993 and January 2018, with the aim of improving elbow flexion as the primary or secondary functional goal. Patients with preoperative elbow flexion Medical Research Council (MRC) grades less than 3 with more than or equal to 18 months of follow-up duration were included in the analysis. Patient demographic information and pre/postoperative clinical parameters including elbow flexion MRC scale, passive elbow range of motion, and complications were recorded. Surgical data including donor nerve choice, site of the FFMT tendon attachment, and necessity of concomitant procedures or reoperation were also analyzed. Results Fifty-six FFMTs were performed for the primary (29 patients) or secondary (26 patients) objective of restoring elbow flexion. The mean age at the time of the procedure was 9.6 years (standard deviation [SD] = 6.29, R = 3-35). Mean follow-up was 7.9 years (SD = 5.2). Elbow flexion improved from a median MRC grade 2 to 4 after a FFMT (p < 0.05). Patients who had a FFMT to restore two functions had 86% lower elbow flexion MRC grades than those who had a FFMT to restore flexion only (p < 0.05). Patients less than 12 years old at the time of surgery had more complications, reoperations, and rates of a flexion contracture more than or equal to 30 degrees than those aged more than 12 years (p < 0.05). Conclusion FFMT is a reliable option for upper extremity reanimation. Patients aged less than 12 years old at the time of FFMT had significantly more complications, reoperations, and rates of postoperative elbow flexion contracture more than or equal to 30 degrees, but equivalent elbow flexion MRC grades.

Global brachial plexus injury (GBPI) mainly affects adults and causes severe life-changing consequences that lead to the deterioration of patients’ quality of life. Several surgical approaches have been described and reported in the literature to improve patients’ functional ability. A literature review is done on PubMed/ MEDLINE and Embase using specific keywords to retrieve relevant articles assessing different surgical approaches for GBPI management. Inclusion and exclusion criteria were applied, and eligible articles were included in the review. The literature survey revealed that various surgical options had been used to manage GBPI patients. In this concise review, we discuss and compare the different surgical approaches related to GBPI and its outcome in terms of restoring elbow flexion and extension, shoulder abduction, and wrist and hand function. The primary surgical intervention relies mainly on transferring single or multiple nerves with/without nerve grafts to restore the function of the targeted muscle. Different techniques using a variety of nerve donors and recipients are compared to assess the functional outcomes of each option. Moreover, further options are addressed for delayed GBPI injuries or failed nerve transfer procedures, as in free functional muscle transfer techniques. In addition, information about brachial plexus injury cases faced in our center is presented along with our center’s approach to diagnosing and managing partial and GBPI cases.

Purpose: Traumatic brachial plexus injury (TBPI) causes severe disabilities to the patients, affecting not only upper limb function but also the psychosocial and economic aspects. Free functional muscle transfer (FFMT) is one of the reconstruction modalities for the management of TBPI. The aim of this study is to evaluate the functional outcomes and their correlation to patient factors. Patients and Methods: This is a retrospective study of 131 patients who suffered from complete TBPI (C5-T1) and were treated with the FFMT procedure to restore elbow flexion and wrist extension from 2010 to 2018 in our institution. We evaluated the active range of motion (AROM), muscle power with MRC (Medical Research Council) scale, DASH score, and complications, with a minimum of 12-month follow-up. Results: Following FFMT surgery, elbow flexion was significantly and successfully restored (MRC ≥ 3) in 75.5% of patients with an average AROM of 88.17 ± 41.29°. The wrist extension was restored in 42% of the patients with an average AROM of 20.69 ± 18.72°. There was no correlation between age, side of injury, and time to surgery with the functional outcomes. There was a weak correlation between education level, rehabilitation compliance, and elbow functional outcomes. Conclusion: FFMT is a reliable surgical option to restore elbow flexion in TBPI with a high satisfactory result. Our findings suggested that the FFMT indication is potentially expanded regardless of the patient factors. [ABSTRACT FROM AUTHOR]

Background  Postparalytic synkinesis presents with a combination of hypo- and hypertonic muscles, leading to facial asynchrony with animation and at rest. One ubiquitous finding is a hypertonic depressor anguli oris (DAO) muscle and a weak depressor labii inferioris (DLI) muscle. The goal of this study was to evaluate the utility of DAO myectomy with or without its transfer to the weakened DLI in improving critical components of the dynamic smile. Methods  From 2018 to 2020, this single-center, prospective study included of postparetic facial synkinetic patients with evidence of DAO hypertonicity who underwent DAO myectomy with or without transfer to DLI. Objective facial measurements were used to compare the effectiveness of DAO to DLI transfer to pure DAO myectomy in improving asymmetry of the synkinetic hemiface. Results  Twenty-one patients with unilateral postparetic facial synkinesis with DAO hypertonicity were included; 11 underwent DAO myectomy, while 10 underwent DAO to DLI transfer. Baseline demographics and facial measurements were similar between the groups. DAO myectomy resulted in increased modiolus resting position, closed-mouth smile modiolus angle and excursion, open-mouth smile modiolus angle, excursion, dental show, and decreased lower lip height deviation. DAO to DLI transfer demonstrated similar findings but lacked significant increase in excursion and resulted in worsened lower lip height deviation. Conclusion  These findings illustrate the utility of DAO myectomy in improving imbalance in the synkinetic patient and necessitate further technical refinements for DAO transfers or a different approach for improving lower lip depression in this subgroup of patients.

Aims: The aim of facial reanimation isto restore facial symmetry in spontaneous, mimic, and emotional movements. One of the important reconstructive treatment optionsin patients with long-term facial paralysisisfree muscle transfers. The firststage in two-stage muscle transfers is the cross facial nerve graft (CFNG). In this study, our aim is to investigate the importance of Tinel’s sign and EMG in the selection of patients who have had CFNG due to long-term facial paralysis and who can undergo muscle transfer repair and investigate the effectiveness of these methods. Patients and Methods: Ten patients who underwent crossfacial nerve grafting for long-term facial nerve paralysis between 2012 and 2018 were prospectively included in the study. Results: No complications were observed during the operation and follow-up of the patients. The reliability of EMG is lower than the Tinel’s sign when making a muscle transfer decision in patients who undergo CFNG. Conclusions: In conclusion, the etiology of facial paralysis (severity of injury in traumatic paralysis), age of patients, comorbid conditions, surgical experience, postoperative physical therapy process and patient compliance play an active role in providing reinnervation.

Purpose: Quantifying changes in shoulder external rotation range of motion and strength after lower trapezius transfer in children with obstetric brachial plexus palsy (OBPP). Methods: This prospective study included five children with sequelae of OBPP, with a mean age of 6.4 years (range: 4–12 years) who underwent lower trapezius tendon transfer to restore active external rotation (ER) of the shoulder. Pre-operatively and at a 12-month follow-up assessment, we analyzed the passive and active shoulder ER, the modified Mallet score, and the shoulder rotator muscles strength using an isokinetic device. Results: Clinical parameters improved significantly after trapezius transfer pre-operative passive ER from −8° (range: −20–0°) to 37° (range: 15–50°) (p = 0.035), the modified Mallet score from 13 (range: 10–15) to 18 (range: 17–19) (p = 0.035). Strength testing revealed improved ER muscle strength in all five cases; the mean Peak Torque increased from 1.95 to 4.46 N·m, albeit non-significantly (p = 0.062). Two patients exhibited a winged scapula post-operatively. Conclusion: Lower trapezius transfer seems encouraging to restore shoulder external rotation in OBPP children but with non-significant strength improvement.

Aims: To review patients treated with a functional latissimus dorsi flap for congenital and acquired elbow flexion deficits. Methods: Retrospective review of functional latissimus dorsi flaps performed in one regional unit. Patient notes were reviewed to determine aetiology, pre-op deficits and function, surgical technique, complications and outcomes. Results: A total of six functional latissimus dorsi transfers were performed on four patients. Two patients had bilateral latissimus dorsi transfers for congenital defects. The remaining two procedures were for traumatic defects. Post-operatively both children had excellent outcomes with full range of active movement allowing them to perform key activities of daily living. Surgical Technique: Epimysium of latissimus dorsi folded to form a pseudo-tendon, tunnelled subcutaneously and either attached to a remnant of biceps tendon or secured to the radius. Congenital patients achieved better outcomes; pre-operatively, there was no active elbow flexion in all four elbows but 90–100 of passive flexion. Complications: One latissimus dorsi dehiscence which required revision surgery. Two donor-site seromas. Conclusions: Functional latissimus dorsi transfer has been shown to achieve excellent elbow flexion in patients with congenital absence of biceps and brachialis muscles. Outcomes in older patients with traumatic injuries have been less successful in achieving a full range of active flexion. [ABSTRACT FROM AUTHOR]

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.

Purpose: The primary objective of this retrospective study was to validate electrophysiological results of latissimus dorsi tendon transfer (LDTT) to determine if this transfer is active for different daily living tasks, and the secondary objective was to correlate these clinical results.Methods: With a mean follow-up of 4.7 years, 14 latissimus dorsi tendon transfers were retrospectively reviewed. Patients were clinically evaluated with the constant score and the SSV. Healing of the tendon on the greater tuberosity and atrophy of the LDTT muscle was determined by ultrasound and compared with the contralateral side. Electrical activity was analyzed by electromyography in active elevation, abduction, and external rotation.Results: Twelve patients are satisfied (SSV). At the last follow-up, the EMG found a significant electrical activity in the abduction and external rotation and a lower activity in adduction and internal rotation. The mean constant score increased from 29 to 51, the mean forward elevation increased from 89° to 135°, the mean abduction from 92° to 105°, and the external rotation from 12° to 24°. The ultrasound found 12 healed tendons and two ruptures at the myotendinous junction.Conclusion: Electrical activity in abduction and external rotation testifies that the LDT transfer acts as an active muscle transfer and acts not only a muscle tenodesis that covers the humeral head.

Purpose: This systematic review assesses evidence for improvements in outcome for all reported types of treatment modalities [physical therapy, tenotomy or tenodesis of the long head of the biceps, debridement, partial repair, subacromial spacer, deltoid flap, muscle transfer, rotator cuff advancement, graft interposition, superior capsular reconstruction (SCR), and reversed shoulder arthroplasty (RSA)] used for irreparable posterosuperior rotator cuff tears without glenohumeral osteoarthritis. The primary aim was to be able to inform patients about expectations of the amount of clinical improvement after these treatments.Methods: A systematic search was conducted in MEDLINE, EMBASE, CINAHL, and Cochrane databases for studies on irreparable posterosuperior rotator cuff lesions without glenohumeral osteoarthritis, published from January 2007 until January 2019, with minimum 2-year follow-up. Studies with pre-operative and/or intra-operative determination of cuff tear irreparability were included. We defined the non-adjusted Constant Score as the primary outcome.Results: Sixty studies (2000 patients) were included with a fair mean quality score, according to the Modified Coleman Methodology Score. The employed definitions of 'irreparable' were mainly based on MRI criteria and were highly variable among studies. The smallest weighted mean preoperative to post-operative improvements in Constant Score were reported for biceps tenotomy/tenodesis (10.7 points) and physical therapy (13.0). These were followed by debridement (21.8) and muscle transfer (27.8), whereas the largest increases were reported for partial repair (32.0), subacromial spacer (32.5), rotator cuff advancement (33.2), RSA (34.4), graft reconstruction (35.0), deltoid flap (39.8), and SCR (47.4). Treatment using deltoid flap showed highest mean weighted improvement in Constant Score among studies with available medium-term (4-5-year) follow-up. Treatments deltoid flap, muscle transfer, and debridement were the only treatments with available long-term (8-10-year) follow-up and showed similar improvements in Constant Score at this time point.Conclusion: The variability in patient characteristics, co-interventions, outcome reporting, and length of follow-up in studies on irreparable rotator cuff tears without osteoarthritis complicates sound comparison of treatments. Clinically important treatment effects were seen for all 11 different treatment modalities.Level Of Evidence: IV. [ABSTRACT FROM AUTHOR]

Elbow flexion is widely regarded as the most important function to restore in brachial plexus injuries. Free functioning muscle transfer surgery is indicated in patients with delayed presentation or failure of other primary procedures. Results of the transfer surgeries have been reported in the form of case series, but no further studies are available. This systematic review aims to provide a deeper understanding of this complex surgery and consists of 19 articles that include 364 patients. Data on injury characteristics, surgical techniques, complications as well as outcome measures were analysed. Our results show that functional muscle transfer for elbow flexion enables 87% and 65% of patients to achieve a useful power grade of ≥ 3 and ≥ 4, respectively, although other important outcome factors should be considered.

The purpose of this study was to evaluate long-term outcomes of the free functioning gracilis transfer in children with traumatic total brachial plexus palsy. We used the free functioning gracilis transfer to reconstruct elbow flexion and prehension in 17 children with a mean age of 13.4 years (range 3–17) who were followed-up over a mean period of 6 years (range 2–16). The transferred gracilis delivered a stable elbow flexion with a useful power, as well as reconstructed active finger motion. In 3–11-year-old patients we noted a tendency towards developing a progressive flexion contracture of the elbow. The limb length discrepancy observed in our patients was not different from the brachial plexus palsy patients treated without the free functioning gracilis transfer. In conclusion, the free functioning gracilis transfer is a reliable reconstructive technique for reanimating upper extremity in children of all ages capable of delivering stable function over a long period of time.Level of evidence: IV [ABSTRACT FROM AUTHOR]

Background: Arthrogryposis is the general term given to conditions characterized by multiple joint contractures resulting in substantial disability most frequently involving a child. Early muscle transfer reconstructive surgery reliably restores elbow flexion. In the present study, we aimed to determine which preoperative condition is best able to restore elbow flexion in patients with arthrogryposis. Methods: We retrospectively reviewed five children (seven cases) who underwent elbow flexor reconstruction (Steindler flexorplasty, four cases; latissimus dorsi transfer, two cases; pectoralis major transfer, one case). Upper-extremity function was assessed on the basis of range of elbow extension and flexion and elbow flexor muscle power pre- and postoperatively. Results: The mean postoperative active flexion and extension range of motion was 82.1° (60° to 100°) and -15.0° (-40° to 0°) respectively. Mean postoperative elbow flexor muscle power was graded as a 3.4 (2 to 4) as measured with the Medical Research Council (MRC) scale. The preoperative passive elbow flexion angle was found to correlate with postoperative muscle power (MRC) (r = 0.830, p = 0.042) and postoperative active elbow flexion angle (r = 0.902, p = 0.027). Age at operation was not found to correlate with postoperative muscle power (MRC) (r = -0.063, p = 0.878) or active elbow flexion angle (r = -0.134, p = 0.743). Conclusions: We found a positive correlation between preoperative passive elbow flexion/range of elbow motion and postoperative results including active range of motion and transferred muscle power. Diminished preoperative elbow flexion appeared to correlate with having a poor outcome. The present results suggest that choosing another muscle, such as the gracilis, may be beneficial for muscle transfer in more severe cases of arthrogryposis. [ABSTRACT FROM AUTHOR]

Lengthening temporalis myoplasty (LTM), first described by Labbé in 1997, ensures the transfers of the entire temporal muscle from the coronoid process to the upper half of the lip without interposition of aponeurotic tissue. The temporal muscle changes function because it is entirely mobilized toward another effector: the labial commissure. Thanks to brain plasticity, the muscle loses its chewing function, and after 6 months of speech rehabilitation it acquires its new smiling function. We describe technical points especially the coronoid process approaches both through an upper temporal fossa approach and a lower nasolabial fold approach. Rehabilitation starts 3 weeks after the surgery following a standardized protocol to move from a mandibular smile to a voluntary, then spontaneous, smile in three steps. The LTM is the main part of a one-stage global treatment of the paralyzed face. It constitutes a dynamic palliative treatment usually started at the sequelae stage, 18 month after the outcome of a peripheral facial paralysis. This one-stage procedure is a reproducible and relevant surgical technique in the difficult treatment of peripheral facial paralysis. It allows implementing an active muscle transfer to reanimate the labial commissure and recreate a mobile nasolabial fold. [ABSTRACT FROM AUTHOR]

Purpose: Latissimus dorsi and teres major transfers to the lateral side of the humerus with lengthening of the pectoralis major and subscapularis muscles for residual shoulder deformity were compared in children and skeletally mature patients. Methods: Fifteen patients (nine children, six skeletally mature patients aged three to 30 years, follow-up one to 22 years) were treated for internal shoulder contracture after birth plexus lesions: C5-C6 (seven patients); C5-7 (five patients); C5-C8-T1 (three patients, respectively). Range of movement, Mallet shoulder function score and radiographs were assessed. Results: Pre-operatively, shoulder function restrictions were comparable in all patients. Postoperatively, external rotation, abduction and Mallet function score improved significantly ( p < 0.05) in all patients except one. There were no differences in improvement between children and skeletally mature patients ( p = 0.24-1.0). Conclusions: This technique improves external rotation and abduction of the shoulder for daily living activities in children and young, skeletally mature, patients. [ABSTRACT FROM AUTHOR]

Background: Elbow flexion is often lacking in patients with brachial plexus palsy or anterior arm trauma. Restoring elbow flexion helps position the functioning hand for activity and nonfunctioning hand for stabilization. Bipolar latissimus transfer is one method of improving elbow flexion. Methods: A clinical case of bipolar latissimus transfer is presented. Additionally, results of a literature search are incorporated. Results: Bipolar latissimus can effectively improve elbow function, however residual deficits are to be expected. Additional transfers include unipolar latissimus, triceps, sterno-cleidomastoid, and pectoralis. Other methods include primary nerve transfer, Steindler flexorplasty, free muscle transfer, and elbow fusion. Conclusion: Elbow flexion can be improved through various techniques. Each individual's clinical picture should be examined by an experienced clinician when choosing which technique to apply. [ABSTRACT FROM AUTHOR]

Purpose: Pectoralis major transfer is indicated for irreparable subscapularis tendon tears. One surgical option is transferring the sternal part of the pectoralis major to the humeral insertion of the subscapularis under the conjoined tendon of the coracobrachialis and biceps muscles. The purpose of this study is to define the anatomical relationship between the transferred tendon and the musculocutaneous nerve. Methods: In 52 cadaveric fresh-frozen shoulders, the relevant structures were dissected and a pectoralis major transfer was performed. The relationship between the transferred tendon, the musculocutaneous nerve branches distally and the coracoid process proximally was examined. Measurements were taken at the conjoined tendon level. Results: The distance between the coracoid process and the most proximal musculocutaneous nerve branch was 54.2 ± 33.2 mm. In 25 cases (48 %), the transferred tendon passed freely between both structures. In 16 cases (31 %), there was contact distally with the musculocutaneous nerve. In 11 cases (21 %), there was contact both proximally with the coracoid process and distally with the musculocutaneous nerve, making a safe transfer impossible. Conclusions: When performing a pectoralis major transfer, it is essential to identify the musculocutaneous nerve and its branches. In some cases, a subcoracobicipital transfer may not be feasible and a more superficial transfer should be considered. [ABSTRACT FROM AUTHOR]

The use of the free functioning, innervated gracilis muscle has evolved to become an invaluable tool in the restoration of elbow flexion and prehension in patients undergoing reconstruction following brachial plexus injuries. Although there are many different methods of the gracilis muscle harvest, most if not all harvest methods begin proximally. The purpose of this article is to describe a novel distal harvest technique of the gracilis myocutaneous flap for brachial plexus patients requiring restoration of elbow or finger flexion. A harvest method commencing with a distal dissection either at the distal insertion of the gracilis at the pes anserine or at the distal medial thigh at the myotendinous junction will be described. The advantage of this novel method is to ensure that the entire gracilis muscle and its tendon are harvested to maximize the length of tendon that can be secured by a Pulvertaft weave into the biceps tendon or the finger flexors for elbow flexion and finger flexion respectively.

Background: Traumatic brachial plexus injury is a devastating condition resulting mainly from motor cycle accidents and primarily affecting the young adults. In the past there was a pessimistic attitude in the management of these injuries. However in last two decades with the introduction of microsurgical techniques and advances in imaging modalities, these injuries are being explored and repaired early with satisfactory to good functional out comes. Methods: Neurolysis, nerve repair, nerve grafting, nerve transfer, pedicle muscle transfer and functioning free-muscle transfer are the main surgical procedures in the management of brachial plexus injury. In the management of these injuries an immediate intervention is considered in penetrating trauma. All other common high velocity traction injuries are initially observed for a spontaneous recovery. If there are no signs of recovery by three months, surgery is indicated, as further delay will affect the ultimate results. In global brachial plexus palsy with all root avulsions, intervention is even earlier, as chances of spontaneous recovery are practically nil. Results: Good results are expected with early intervention in upper plexal lesions. Results are favorable with short nerve grafts, distal nerve transfers, and intraplexal neurotization. The aim in global brachial plexus palsy is to restore the elbow flexion and provide a stable shoulder. Restoration of a fully functional and sensate hand is still far from being a reality. Conclusion: The management of brachial plexus injury remains a challenging problem. Functional results have considerably improved in the past two decades with the incorporation of microsurgical techniques in nerve surgery, and advancements in anesthesia. Following microsurgical reconstruction many of these patients are expected to return to their original work and amputation is no longer considered a treatment option. [ABSTRACT FROM AUTHOR]

Facial paralysis is a clinical entity associated with significant morbidity, which has a treatment paradigm that is continually evolving. Surgical management of the paralyzed face poses significant challenges to achieve the goal of returning patients to their premorbid states. Here we attempt to review the advances in facial reanimation, in particular with regards to chronic facial paralysis. These include recent developments in static and dynamic rehabilitation including advances like artificial muscles for eyelid reconstruction, dynamic muscle transfer for the eye, and orthodromic temporalis tendon transfer.

Elbow extension is a prerequisite for adequate hand position. Muscle transfers are often employed in partial injuries of the brachial plexus, when neurological surgery is unlikely to achieve desired results. The posterior deltoid and latissimus dorsi are the two muscles most commonly used for transfer but there are few alternatives when these two muscles are paralysed. We now report on the successful transfer of the lower trapezius muscle to reconstruct triceps function in three patients with longstanding lesions of the brachial plexus that had not been previously treated surgically.

Seven patients (five men and two women) ranging in age from 26 to 65 years (=44) underwent bilateral gluteus maximus transposition for complete anal incontinence. The indications for operation were sphincter destruction secondary to multiple fistulotomies (n=4), bilateral pudendal nerve damage (n=2), and high imperforate anus (n=1). The procedure is performed without the use of a diverting colostomy. The inferior portion of the origin of each gluteus maximus is detached from the sacrum and coccyx, bifurcated, and tunneled subcutaneously to encircle the anus. The ends are then sutured together to form two opposing slings of voluntary muscle. Postoperatively, six patients regained continence to solid stool, two to liquid stool as well, and only one patient in this group was able to control flatus. Although resting pressures remained unchanged, voluntary squeeze pressures were restored by this operation. In addition, rectal sensation was markedly improved, which helps make this a worthwhile procedure for properly selected patients. [ABSTRACT FROM AUTHOR]
