Uma rara apresentação de plexopatia braquial por empiema de necessidade / A rare presentation of brachial plexopathy due to need empyema

Contexto: O empiema tem aumentado sua incidência ao longo das últimas décadas e ainda é a complicação mais comum de pneumonias. Apesar dos avanços no tratamento clínico, o acometimento do tecido pleural por infecções pode levar a sequelas irreparáveis e ainda apresenta uma alta mortalidade. Descrição do caso: Paciente do sexo masculino, 55 anos de idade, relatou queixa de dor em hemitórax e ombro esquerdos e parestesia difusa em membro ipsilateral há três dias. Tomografia de tórax revelou empiema pleural em lobo superior esquerdo e eletroneuromiografia evidenciou plexopatia braquial. Foi feita a punção guiada do empiema que demonstrou infecção por Staphylococcus aureus sensível à meticilina. Após drenagem do abscesso e antibioticoterapia, o paciente apresentou melhora progressiva dos sintomas. Discussão: O empiema de necessidade raramente se apresenta secundário a uma infecção bacteriana aguda, sendo geralmente causado por longas efusões pneumônicas tuberculosas. Sua manifestação clínica mais comum é a presença de massa dolorosa na região anterior do tórax, com exames de imagem mostrando alterações inflamatórias. A terapêutica preconizada se constitui de drenagem e antibioticoterapia. Conclusão: O diagnóstico de empiema de necessidade foi poucas vezes descrito na literatura e deve ser suspeitado em quadros infecciosos pulmonares com repercussão neurológica em plexo braquial.

Evaluation of Long-Term Results of Oberlin Surgery in Obstetric Brachial Paralysis / Avaliação dos resultados a longo prazo da cirurgia de Oberlin na paralisia braquial obstétrica

Abstract Objective To evaluate elbow flexion in children with obstetric brachial plexus paralysis submitted to Oberlin transfer. Methods Retrospective study with 11 patients affected by paralysis due to labor who did not present spontaneous recovery from elbow flexion until 12 months of life, operated between 2010 and 2018. Results The children were operated between 5 and 12 months of life, with a mean of 7.9 months, and the mean follow-up time was 133.2 months, ranging from 37 to 238 months. Six patients (54.5%) presented a degree of muscle strength ≥ 3, measured by the strength scale of the Medical Research Council (MRC) and, according to the active movement scale (AMS), 5 patients obtained a score of ≥ 5. A negative correlation was identified between the AMS and the Narakas classification (r = -0.509), as well as between the strength scale (MRC) and the Narakas classification (r = -0.495). A strong positive correlation was observed (r = 0.935) between the AMS and the MRC demonstrating that the higher the score on the movement scale, the higher the score on the muscle strength scale. Conclusion The Oberlin surgery is a possible option for recovery of elbow flexion in children with neonatal plexopathy, demonstrating, however, very heterogeneous results, even in the long-term follow-up.

Resumo Objetivo Avaliar a flexão do cotovelo em crianças portadoras de paralisia obstétrica do plexo braquial submetidas à transferência de Oberlin. Métodos Estudo retrospectivo com 11 pacientes acometidos por paralisia decorrente do trabalho de parto e que não apresentaram recuperação espontânea da flexão do cotovelo até os 12 meses de vida, operados entre 2010 e 2018. Resultados As crianças foram operadas entre os 5 e 12 meses de vida, com média de 7,9 meses e o tempo médio de seguimento foi de 133,2 meses, variando de 37 a 238 meses. Seis pacientes (54,5%) apresentaram grau de força muscular ≥ 3, medido pela escala de força do Medical Research Council (MRC), e, pela escala de movimentação ativa (Active Momement Scale [AMS]), 5 pacientes obtiveram pontuação ≥ 5. Foi identificada correlação negativa entre a AMS e a classificação de Narakas (r = -0,509), bem como entre a MRC e a classificação de Narakas (r = -0,495). Já entre a AMS e a MRC, foi observada forte correlação positiva (r = 0,935), demonstrando que quanto maior a pontuação na escala de movimento, maior será a pontuação na escala de força muscular. Conclusão A cirurgia de Oberlin apresenta-se como uma opção possível para a recuperação da flexão do cotovelo em crianças com plexopatia neonatal; no entanto, demonstra resultados bastante heterogêneos, mesmo no seguimento a longo prazo.

Epidemiological Profile of Surgically-Treated Peripheral-Nerve Diseases

Objective To outline the epidemiological profile of surgical patients treated at the peripheral-nerve outpatient clinic of a public hospital in the state of Pernambuco, Brazil, from 2008 (the year this service was implemented in the hospital ) to 2016. Material and Methods A cross-sectional study with data collection from the medical records. A descriptive analysis was performed with the qualitative variables presented as relative and absolute frequencies, and the quantitative variables, as means and standard deviations. The studied variables were gender, age, diagnosis, and surgical techniques. Results In total, 506 medical records were analyzed. Of these, 269 were of male patients (53%), and 238 were of female patients (46%). The age of the sample ranged from 5 to 84 years (41 14 years). The most prevalent diagnoses were: carpal tunnel syndrome (38.9%) followed by traumatic brachial plexus injury (33.2%). The first diagnosis was more frequent among women, while the second, among men. This collaborates with the predominant findings of upper-limb lesions (91%), in which men accounted for 52,75% (244) and women, for 47,25% (217). Conclusion The present study provided relevant information regarding the reality of peripheral-nerve surgeries performed at a public hospital in the state of Pernambuco, Brazil. Public health issues increasingly require the continuity of public policies and government incentive.

Transferencias tendíneas alrededor del hombro para paciente con secuelas de lesiones de plexo braquial / Tendon transfers around the shoulder for patient with brachial plexus injury sequels

Resumen: Las lesiones de plexo braquial pueden afectar de forma muy significativa la función de los pacientes. El tipo de manejo va a depender de la severidad de la lesión como también de la localización anatómica de ésta. Las transferencias tendíneas alrededor del hombro han surgido como una alternativa efectiva de tratamiento y por lo tanto, debemos considerarlas cuando nos vemos enfrentados a pacientes que la podrían requerir. Existen diversas técnicas de transferencia, las que se utilizan con más frecuencia son las transferencias de trapecio superior, de dorsal ancho y de trapecio inferior, cada una con sus indicaciones y objetivos específicos según el tipo de paciente. Estas cirugías tienen como propósito disminuir el dolor producto de la hipotonía y subluxación glenohumeral como también mejorar el rango de movimiento del hombro, logrando que el paciente lleve su mano al plano que requiera para realizar sus actividades de la vida diaria. Presentaremos algunas de las técnicas de transferencia tendínea de hombro más utilizadas asociadas a una revisión bibliográfica y una descripción de nuestra experiencia con estas cirugías.

Abstract: Brachial plexus lesions can significantly affect patient function. The type of management will depend on the severity of the injury as well as the anatomical location. Tendon transfers around the shoulder have emerged as an effective treatment alternative, and therefore we should consider them when faced with patients who might require it. There are various transfer techniques, within which the most frequently used are upper trapezium, latissimus dorsi and lower trapezium transfers, each with its specific indications and objectives depending on the type of patient. These surgeries aim to decrease the pain resulting from the hypotonia and glenohumeral subluxation as well as improve the range of movement of the shoulder, getting the patient to take his hand to the plane that requires to perform his daily life activities. We will provide a description of some of the most commonly used shoulder tendon transfer techniques associated with a bibliographic review and a description of our experience with these surgeries.

Treatment of radiation-induced brachial plexopathy with omentoplasty

Radiation-induced brachial plexus neuropathy (RIBPN) is a rare and delayed non-traumatic injury to the brachial plexus, which occurs following radiation therapy to the chest wall, neck, and/or axilla in previously treated patients with cancer. The incidence of RIBPN is more common in patients treated for carcinoma of the breast and Hodgkin lymphoma. With the improvement in radiation techniques, the incidence of injury to the brachial plexus following radiotherapy has dramatically reduced. The currently reported incidence is 1.2% in women irradiated for breast cancer. The progression of symptoms is gradual in about two-thirds of cases; the patients may initially present with paresthesia followed by pain, and later progress to motor weakness in the affected limb. We present the case of a 68-year-old female patient with breast cancer submitted to surgery, chemotherapy, and radiotherapy in the year 2000. Eighteen years later, she developed symptoms and signs compatible with RIBPN and was successfully submitted to omentoplasty for pain control. Omentoplasty is an alternative treatment for RIBPN refractory to conservative treatment, which seems to be effective in improving neuropathic pain. However, postoperative worsening of the motor strength is a real possibility, and all candidates for this type of surgery must be informed about the risk of this complication.

Síndrome de Parsonage-Turner en paciente sometido a cirugía de revascularización miocárdica. caso clínico / Parsonage-Turner syndrome: report of one case

We report a 59-year-old male who, three weeks after a coronary revascularization surgery, reported a sudden intense burning pain in his left upper limb. Two weeks later, he reports a paresis with difficulty to extend his left wrist and fingers. The electromyography showed a severe axonal damage of the radial nerve with distal denervation signs. This clinical picture probably corresponds to a neuralgic amyotrophy, an inflammatory disorder of the brachial plexus known by a number of terms, including Parsonage-Turner syndrome.

Lesión del nervio axilar asociado a luxación de hombro / Axillary nerve injury associated with shoulder dislocation: case report

Resumen: La lesión del nervio axilar (o circunflejo) aislada es poco frecuente, ésta suele presentarse asociada a una lesión del plexo braquial. En nuestra institución, en un período comprendido entre los años 2015-2017, se ha observado una frecuencia de sólo 0.4% de esta lesión. Con el presente reporte de caso se resalta la relación de la luxación de hombro con lesión del nervio axilar aislada. Caso clínico: Masculino de 31 años de edad, con trauma en hombro derecho, secundario a caída de su propia altura en accidente laboral. Radiografía de ingreso de hombro derecho muestra luxación anteroinferior de articulación glenohumeral, asociada a fractura de troquiter. Es intervenido quirúrgicamente, con reducción cerrada de articulación glenohumeral y osteosíntesis de troquiter. Posterior a ello, el paciente presenta atrofia marcada del deltoides, se ordena electromiografía que evidencia lesión completa del nervio axilar sin reinervación.

Abstract: Isolated lesion of the axillary (or circumflex) nerve is infrequent, this is usually associated with a brachial plexus injury. In our institution, in a period comprised between the years 2015-2017, a frequency of only 0.4% of this injury has been observed. Clinical case: Male patient of 31 years of age, with trauma in the right shoulder, caused by fall of his own height in work accident. The admission graph of the right shoulder shows anterior inferior dislocation of the glenohumeral joint, associated with a greater tubercle fracture. He underwent surgery, with closed reduction of the glenohumeral joint and osteosynthesis of the greater tubercle. The patient later presents marked atrophy of the deltoid, electromyography is ordered that shows complete lesion of the axillary nerve without reinnervation.

Prolonged brachial plexopathy following interscalene block for shoulder arthroplasty / Plexopatía braquial prolongada después de un bloqueo interescalénico en cirugía de hombro

Abstract Interscalene block (ISB) is the brachial plexus approach most frequently used in shoulder surgery, providing better postoperative analgesia and reducing the need for rescue morphine compared to general anesthesia. While it is considered a safe block, it has been associated with a relatively high rate of complications, the most serious of which are postoperative neurologic symptoms, such as paresthesia, dysesthesia, and reduced sensitivity. We present the case of a patient with prolonged neurological deficit lasting 4 months following nerve stimulation-guided ISB. Due to the multifactorial nature of postoperative neurological lesions, it can be difficult to determine their etiology. In our case, the brachial plexopathy was probably due to the administration of local anesthetic through the perineurium. We discuss possible causes and argue for the use of ultrasound associated with nerve stimulation when an ISB is performed in order to reduce the incidence of nerve puncture.

Resumen El bloqueo Interescalénico (BIE) es el abordaje al plexo braquial usado con mayor frecuencia en cirugía de hombro, que permite una mejor analgesia postoperatoria y reduce la necesidad de morfina de rescate, en comparación con la anestesia general. Si bien es cierto que se considera un bloqueo seguro, se ha asociado a una tasa de complicaciones relativamente alta, siendo la complicación más seria los síntomas neurológicos postoperatorios (SNPO), tales como parestesia, disestesia, y pérdida de la sensibilidad. Presentamos el caso de un paciente con déficit neurológico prolongado de 4 meses de duración, luego de BIE guiado por neuroestimulación. Debido a la naturaleza multifactorial de las lesiones neurológicas postoperatorias, puede ser difícil determinar su etiología. En nuestro caso, la plexopatía braquial se debió posiblemente a la administración de anestésico local (AL) a través del perineuro. Hacemos referencia a las posible causas y la opción de ultrasonido asociado a la neuroestimulación cuando se realiza un bloqueo interescalénico, a fin de reducir la incidencia de punción del nervio.

Restoration of Elbow Flexion in Traumatic Upper Brachial Plexus Palsy in Adults: Outcome with Intraplexus Distal Nerve Transfers in 78 Patients

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 themedian 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 þ 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.

Elective amputation of the upper limb is an option in the treatment of traumatic injuries of the brachial plexus? / A amputação eletiva do membro superior é uma opção no tratamento das lesões traumáticas do plexo braquial?

ABSTRACT The treatment of complete post-traumatic brachial plexus palsy resulting in a flail shoulder and upper extremity remains a challenge to peripheral nerve surgeons. The option of upper limb amputation is controversial and scarcely discussed in the literature. We believe that elective amputation still has a role in the treatment of select cases. The pros and cons of the procedure should be intensely discussed with the patient by a multidisciplinary team. Better outcomes are usually achieved in active patients who strongly advocate for the procedure.

RESUMO O tratamento das paralisias completas após lesões traumáticas do plexo braquial que resultam em um membro superior completamente paralisado permanecem como um desafio aos cirurgiões de nervos periféricos. A opção de amputar o membro superior é controversa e raramente discutida na literatura. Acreditamos que a amputação eletiva ainda tem utilidade no tratamento de casos selecionados. Os prós e contras do procedimento devem ser intensamente discutidos com o paciente por uma equipe multidisciplinar. Os melhores resultados são geralmente obtidos em pacientes atuantes que reivindicam vigorosamente o procedimento.

Correlation between motor function recovery and daily living activity outcomes after brachial plexus surgery / Correlação entre a recuperação motora funcional e as atividades de vida diária após cirurgia do plexo braquial

ABSTRACT Objective To establish the correlation between clinical evaluation of motor function recovery and daily living activities in 30 patients with upper traumatic brachial plexus injury submitted to surgery. Methods The score of the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire and the Louisiana State University Health Sciences Center (LSUHSC) scale were determined in 30 patients. Epidemiologic factors were also examined and correlations were determined. Results There was a significant correlation between the clinical evaluation and the daily living activities after a 12-month period (r = 0.479 and p = 0.007). A direct correlation was observed between the functional recovery of the upper limb and the time between injury and surgery (r = 0.554 and p = 0.001). The LSUHSC scores (p = 0.049) and scores from the DASH questionnaire (p = 0.013) were better among patients who returned to work. Conclusions Clinical evaluation and daily living activities in adult patients who underwent nerve transfer after brachial plexus injury showed significant and measurable improvements.

RESUMO Objetivo Avaliar a correlação entre a avaliação clínica e as atividades de vida diária em 30 paciente adultos com lesão do plexo braquial superior. Métodos O valor do questionário Dash (Disabilities of the Arm, Shoulder and Hand) e da escala Louisiana State University Health Sciences Center (LSUHSC) foram quantificados prospectivamente em 30 pacientes. Fatores epidemiológicos foram também examinados e correlações específicas determinadas. Resultados Houve correlação significativa entre avaliação clínica e as atividades de vida diária 12 meses após a cirurgia (r = 0.479 e p = 0.007). Uma correlação direta foi observada entre a recuperação funcional do membro superior e o tempo entre a lesão e a cirurgia (r = 0.554 e p = 0.001). Os valores da escala LSUHSC (p = 0.049) e do DASH (p = 0.013) foram melhores entre aqueles que retornaram ao trabalho. Conclusões A avaliação clínica e as atividades de vida diária em pacientes submetidos à cirurgia de transferência de nervos após lesão do plexo braquial mostraram correlação significativa.

Correlation between the elbow flexion and the hand and wrist flexion after neurotization of the fascicles of the ulnar nerve to the motor branch to the biceps / Correlação da flexão do cotovelo com a flexão da mão e do punho após neurotização dos fascículos do nervo ulnar para ramo motor do bíceps

ABSTRACT OBJECTIVE: Gain in elbow flexion in patients with brachial plexus injury is extremely important. The transfer of a fascicle from the ulnar nerve to the motor branch of the musculocutaneous nerve (Oberlin surgery) is a treatment option. However, in some patients, gain in elbow flexion is associated with wrist and finger flexion. This study aimed to assess the frequency of this association and the functional behavior of the limb. METHODS: Case-control study of 18 patients who underwent the Oberlin surgery. Group 1 included patients without disassociation of range of elbow flexion and that of the fingers and wrist; Group 2 included patients in whom this disassociation was present. In the functional evaluation, the Sollerman and DASH tests were used. RESULTS: It was observed that 38.89% of the patients did not present disassociation of elbow flexion with flexion of the wrist and fingers. Despite the existence of a favorable difference in the group with disassociation of the movement, when the Sollerman protocol was applied to the comparison between both groups, this difference was not statistically significant. With the DASH test, however, there was a statistically significant difference in favor of the group of patients who managed to disassociate the movement. CONCLUSION: The association of elbow flexion with flexion of the wrist and fingers, in the group studied, was shown to be a frequent event, which influenced the functional result of the affected limb.

RESUMO OBJETIVO: O ganho da flexão do cotovelo em pacientes com lesão no plexo braquial é de suma importância. A cirurgia de transferência de fascículo do nervo ulnar para ramo motor do nervo musculocutâneo (cirurgia de Oberlin) é uma opção de tratamento. Contudo, o ganho da flexão do cotovelo, em alguns pacientes, vem associado à flexão do punho e dos dedos. O objetivo deste trabalho é avaliar a frequência dessa associação e o comprometimento funcional do membro. MÉTODOS: Estudo tipo caso-controle de 18 pacientes submetidos à cirurgia de Oberlin. No Grupo 1 foram incluídos os pacientes que não apresentavam dissociação do ganho da flexão do cotovelo com a dos dedos e do punho; no Grupo 2, os pacientes em que havia dissociação. Os testes de Sollerman e Disabilities of the Arm, Shoulder and Hand (Dash) foram usados na avaliação funcional. RESULTADOS: Observou-se que 38,89% dos pacientes não dissociavam flexão de cotovelo de flexão de punho e dos dedos. Apesar de existir uma diferença favorável ao grupo que dissociava o movimento quando aplicado o protocolo de Sollerman na comparação entre os pacientes dos dois grupos, essa não se mostrou estatisticamente significante. Já no teste Dash, observou-se diferença estatisticamente significante, favorável ao grupo de pacientes que consegue dissociar o movimento. CONCLUSÃO: A associação da flexão do cotovelo com a flexão de punho e dos dedos no grupo estudado mostrou ser um evento frequente, teve influência no resultado funcional do membro acometido.

Endoscopic Sural Nerve Removal in Obstetric Brachial Plexopathy Using Basic Endoscopy Instruments: Technical Note

Introduction The sural nerve (SN) is commonly used for grafting following resection of a neuroma-in-continuity in neonatal brachial plexus lesions (NBPL). The main drawbacks of the current open techniques are large scars and contractures in the late postoperative stage, which may, in severe cases, cause equinovarus contractures. Objective To describe the feasibility and the technical aspects of endoscopic SN harvesting with the use of basic endoscopy instruments and small incisions. Methods Prospective observational study of NBPL subjected to endoscopic nerve harvesting between February of 2012 and February of 2014 in a consecutive series. Patients were operated at the Felício Rocho Hospital (Hospital Felício Rocho) and the Clinical Hospital, Federal University of Minas Gerais (Hospital das Clínicas UFMG), Belo Horizonte/MG, in Brazil. The study outcomes assessed were: scar size, presence or absence of contractures in the calf, bleeding volume (measured by the number of gauzes used) and number of incisions. Only patients with a follow-up longer than 6 months were included. Results Seven patients were selected and twelve endoscopic nerves were endoscopically harvested. The average surgery time was 45 minutes. Nine SNs were harvested through two incisions, and three nerves through three incisions. The estimated bleeding was less than 5ml and there were no complications or contractures during the follow-up period of 6 months to 4 years. Conclusion Sural nerve harvesting in children with NBPL is feasible and it offers the advantage of needing only two or three small incisions using basic endoscopy instruments.

Introdução O nervo sural é a melhor opção para enxertia nas reconstruções microcirúrgicas da plexopatia braquial obstétrica. O método clássico aberto com incisão longitudinal desde o tornozelo até a fossa poplítea ou em incisões em degraus possuem as desvantagens de cicatrizes amplas e contraturas em equinovarus (pé torto). Atualmente, o emprego de endoscópios específicos para a retirada de enxertia de nervos e vasos mostra resultados satisfatórios em relação ao encurtamento do tempo cirúrgico e à redução no tamanho das incisões, mas tem como inconveniente o alto custo de aquisição e manutenção. Objetivo Discutir a viabilidade e descrever nota técnica da retirada do nervo sural utilizando instrumental básico de endoscopia e pequenas incisões. Métodos Estudo observacional prospectivo em pacientes com plexopatia braquial obstétrica submetidos a retirada do nervo sural por endoscopia no período de fevereiro de 2012 a fevereiro de 2014 no Hospital Felicio Rocho e no Hospital das Clinicas UFMG, Belo Horizonte/MG, Brasil. Resultados Sete pacientes foram selecionados e foram retirados doze nervos surais por endoscopia. O tempo médio da cirurgia foi de 45 minutos. Nove nervos surais foram retirados por duas incisões, e três nervos foram retirados por três incisões. O sangramento foi inferior a 5ml e não houve complicações no pós-operatório imediato e tardio em acompanhamento entre 6 meses e 4 anos. Não foram observadas contraturas no período observacional. Conclusão O nervo sural pode ser retirado utilizando duas ou três pequenas incisões por meio de instrumental endoscópico básico em crianças com plexopatia braquial obstétrica.

Transferencia de la cabeza larga del tríceps para la flexión del codo en secuela de lesiones del plexo braquial / Transfer of the long head of triceps for elbow flexion in braquial plexus sequelae

Resumen: La anatomía neurovascular independiente de la cabeza larga del tríceps braquial y su idoneidad como un colgajo muscular libre han sido ampliamente estudiadas. En cambio, la trasposición de esta porción del tríceps para mejorar la flexión de codo ha sido descrita pocas veces. Se describen en este artículo dos casos de secuela de lesión del plexo braquial, en los que se realizó trasposición únicamente de la cabeza larga del tríceps. Se logró mejorar la flexión del codo y se conservó la extensión del mismo.

Abstract: The independent neurovascular anatomy of the long head of the triceps brachii and its suitability as a free muscle transfer have been extensively studied. Instead muscle transposition of the long head of the triceps brachii to enhance elbow flexion has been rarely described. We describe in this paper two cases of injury of brachial plexus sequel in which transposition was performed only on the long head of the triceps. The elbow flexion was improved, the extension was preserved.

High prevalence of neuropathic pain in the hand of patients with traumatic brachial plexus injury: a cross-sectional study / Alta prevalência de dor neuropática em sujeitos com lesão traumática do plexo braquial: um estudo de corte transversal

ABSTRACT Objective To describe the pain profile of patients with traumatic brachial plexus injury. Methods We enrolled 65 patients with traumatic brachial plexus injury. The Douleur Neuropathique 4 questionnaire was used to classify pain and the SF-36 was used to evaluate quality of life. Results The patients with traumatic brachial plexus injury were predominantly young male victims of motorcycle accidents. Pain was present in 75.4% of the individuals and 79% presented with neuropathic pain, mostly located in the hands (30.41%). The use of auxiliary devices (p = 0.05) and marital status (p = 0.03) were both independent predictors of pain. Pain also impacted negatively on the quality of life (p = 0.001). Conclusions Pain is frequent in patients with traumatic brachial plexus injury. Despite the peripheral nervous system injury, nociceptive pain is not unusual. Pain evaluation, including validated instruments, is essential to guide optimal clinical management of patients with the condition.

RESUMO Objetivo Descrever o perfil de dor de sujeitos com lesão traumática do plexo braquial. Métodos Nós incluímos 65 indivíduos com lesão traumática do plexo braquial. O Douleur Neuropathique 4 foi usado para classificar a dor e o SF-36 foi usado para avaliar a qualidade de vida. Resultados Sujeitos com lesão traumática do plexo braquial eram em sua maioria homens jovens, vítimas de acidentes motociclísticos. A dor esteve presete em 75.4% dos indivíduos e 79% deles apresentaram dor neuropática, mais frequentemente localizada nas mãos (30.41%). O uso de dispositivos auxiliares (p = 0.05) e o estado civil foram, ambos, preditores independentes de dor. A dor ainda impactou negativamente da qualidade de vida (p = 0.001). Conclusões A dor é frequente em sujeitos com lesão traumática do plexo braquial. Apesar de envolver uma lesão do sistema nervoso a dor nociceptiva não é infrequente. A avaliação da dor, incluindo instrumentos validados, é essencial para direcionar as condutas clínicas de sujeitos com esta condição.
