ABSTRACT

Se describe el caso clínico de un paciente de 36 años de edad, quien acudió a la consulta de Ortopedia y Traumatología del Hospital General Docente Dr. Juan Bruno Zayas Alfonso de Santiago de Cuba, con un alambrón oxidado, encarnado en la cara palmar de la muñeca derecha, con parestesias en la zona de inervación del nervio mediano. La radiografía reveló que dentro de las estructuras de la muñeca había 10 cm del alambrón, con la porción distal doblada en forma de gancho, por lo cual se le realizó intervención quirúrgica de urgencia. Se utilizó anestesia regional, sedación e isquemia y se extrajo el cuerpo extraño en sentido contrario a la curvatura que presentaba. Luego de pasar el efecto anestésico persistían las parestesias en el pulpejo del índice, que desaparecieron completamente a los 4 meses del accidente. Se incorporó a sus labores habituales a los 2 meses de operado.


The case report of a 36 years patient is described. He went to the Orthopedics and Traumatology Service of Dr. Juan Bruno Zayas Alfonso Teaching General Hospital in Santiago de Cuba, with a rusty big wire, ingrowing in the right wrist palmar face, with paresthesias in the innervation area of the median nerve. The x-ray revealed that inside the wrist structures there was 10 cm of the big wire, with the distal portion bent in hook form, reason why an emergency surgical intervention was carried out. Regional anesthesia, sedation and ischemia were used and the strange body was removed in sense contrary to the bend that presented. After the anesthetic effect eased the paresthesias of the index finger tip persisted that disappeared completely 4 months after the accident. He went back to his usual works 2 months after the operation.

ABSTRACT

Abstract Objective To analyze the anatomical variations of the innervation of the flexor digitorum superficialis muscle and to determine if the branch of the median nerve that supply this muscle is connected to the branches to the extensor carpi radialis brevis and the pronator teres muscles, without tension, and how close to the target-muscles the transfer can be performed. Methods Fifty limbs of 25 cadavers were dissected to collect data on the anatomical variations of the branches to the flexor digitorum superficialis muscle. Results This muscle received innervation from the median nerve in the 50 limbs. In 22 it received one branch, and in 28 more than one. The proximal branch was identified in 22 limbs, and in 12 limbs it shared branches with other muscles. The distal branch was present in all, and originated from the median nerve as an isolated branch, or a common trunk with the anterior interosseous nerve in 3 limbs, and from a common trunk with the flexor carpi radialis muscle and anterior interosseous nerve in another. It originated distally to the anterior interosseous nerve at 38, in 5 on the same level, and in 3 proximal to the anterior interosseous nerve. In four limbs, innervation came from the anterior interosseous nerve, as well as from the median nerve. Accessory branches of the median nerve for the distal portion of the flexor digitorum superficialis muscle were present in eight limbs. Conclusion In 28 limbs with two or more branches, one of them could be connected to the branches to the extensor carpi radialis brevis and pronator teres muscles without tension, even during the pronation and supination movements of the forearm and flexion-extension of the elbow.


RESUMO Objetivo Analisar as variações anatômicas da inervação do músculo flexor superficial dos dedos e determinar se o ramo do nervo mediano destinado a esse músculo pode ou não ser conectado aos ramos para os músculos extensor radial curto do carpo e pronador redondo sem tensão, e quão próximo dos músculos-alvo a transferência pode ser realizada. Métodos Foram dissecados 50 membros de 25 cadáveres para coletar dados sobre as variações anatômicas dos ramos para o músculo flexor superficial dos dedos. Resultados O referido músculo recebeu inervação do nervo mediano nos 50 membros. Em 22 recebeu um ramo, em 28 mais que um. O ramo proximal foi identificado em 22 membros e em 12 compartilhava ramos com outros músculos. O ramo distal estava presente em todos e desprendeu-se do nervo mediano como um ramo isolado ou de um tronco comum com o nervo interósseo anterior em 3 membros, e de um tronco comum com músculo flexor radial do carpo e nervo interósseo anterior em outro. Originou-se distalmente ao nervo interósseo anterior em 38, em 5 no mesmo nível e em 3 proximal ao nervo interósseo anterior. Em quatro recebeu inervação do nervo interósseo anterior, além daquela recebida pelo mediano. Ramos acessórios do nervo mediano para a porção distal do músculo flexor superficial dos dedos estavam presentes em oito membros. Conclusão Nos 28 membros em que existam 2 ou mais ramos, 1 desses poderia ser conectado aos ramos para o músculo extensor radial curto do carpo e pronador redondo sem tensão, mesmo durante os movimentos de pronossupinação do antebraço e flexão-extensão do cotovelo.

ABSTRACT

El síndrome de canal carpiano es una patología frecuente. Si bien el diagnóstico es clínico, la ecografía cumple un rol en caso de duda diagnóstica y como apoyo a proce-dimientos intervencionales.Existen variables anatómicas y distancias de estructuras vasculares útiles de conocer antes de planear un gesto quirúrgico o de infiltración para disminuir el riesgo de lesiones secundarias, en donde la ecografía podría tener un rol.Estudiamos una muestra de 267 ecografías de muñeca con especial hincapié en va-riantes neurogénicas, vasculares o tendinosas que podrían resultar lesionadas en relación a algún procedimiento.


Carpal tunnel syndrome is a frequent pathology. Although the diagnosis is clinical, ultrasound plays a role in case of diagnostic doubt and as support and guide for inter-ventional procedures.There are anatomical variants and distances of vascular structures that may be useful to know before planning a surgical or infiltration procedure to reduce the risk of iat-rogenic injuries, where ultrasound could play a role.We studied a sample of 267 wrists ultrasounds with special emphasis on neurogenic, vascular or tendinous variants that could be injured in relation to procedures.

ABSTRACT

A macrodactilia é uma anomalia congênita infrequente, caracterizada pelo crescimento desproporcional dos tecidos ósseo, gorduroso, nervoso, vascular e dérmico nos dedos das mãos ou dos pés. Existem muitas teorias sobre a sua etiopatogenia, sendo a mais aceita a hiperestimulação por fatores de crescimento enviados através dos nervos. Foram descritos alguns casos associados com a síndrome do túnel do carpo. Apresenta-se um caso clínico de síndrome do túnel do carpo por hipertrofia do nervo mediano, evidenciando um aumento de conteúdo dentro do retináculo flexor, o qual foi tratado cirurgicamente com sucesso pela realização de uma retinaculotomia do ligamento anular do carpo junto a um retalho de transposição tenar adipofascial reverso da região tenariana hipertrofiada visando à cobertura do nervo mediano na região do punho.


Macrodactyly is a rare congenital anomaly characterized by the disproportionate growth of bone, fat, nervous, vascular, and dermal tissue in the digits . There are many different theories about its etiopathogenesis, the most accepted being a hyperstimulation by growth factors conducted through nerves. A few cases have been described in conjunction with carpal tunnel syndrome. Here, a clinical case of carpal tunnel syndrome due to hypertrophy of the median nerve is presented, showing an increase of content within the flexor retinaculum. Successful surgical treatment was accomplished by conducting a retinaculotomy of the anterior annular ligament along with a reverse transposition adipofascial flap of the hypertrophied thenar region for coverage of the median nerve at the wrist.

ABSTRACT

OBJETIVO: Comparar os perímetros ultrassonográfico e cirúrgico do nervo mediano, avaliar o diagnóstico da síndrome do túnel do carpo pela área seccional do nervo mediano, verificar associação entre área seccional do nervo mediano e gravidade da síndrome do túnel do carpo. MATERIAIS E MÉTODOS: Estudo de 30 pacientes com síndrome do túnel do carpo. Mediram-se a área seccional e o perímetro ultrassonográfico do nervo mediano. Avaliaram-se correlação clínica-ultrassonográfica e associação com a gravidade da doença. Compararam-se os perímetros ultrassonográfico e cirúrgico. Compararam-se classificação clínica com perímetro cirúrgico, área seccional e perímetro ultrassonográfico. RESULTADOS: Cinco perdas, 25 pacientes estudados; 60% dos pacientes com doença moderada, 60% de casos graves ultrassonográficos (área seccional > 0,15 cm2). Distribuição não normal de perímetro cirúrgico (p = 0,5), distribuição normal de perímetro ultrassonográfico (p = 0). Diferença significativa entre perímetros (teste-t de amostras pareadas; p < 0,0001; intervalo de confiança = 95%). Pearson 0,3913. Pelo diagrama de Bland-Altman, observaram-se maiores perímetros cirúrgicos. Encontrou-se área seccional do nervo mediano > 0,09 cm2 em todos os pacientes. CONCLUSÃO: Não houve associação entre perímetro ultrassonográfico e perímetro cirúrgico do nervo mediano. Área seccional do nervo mediano > 0,09 cm2 foi válida para o diagnóstico. Não houve associação entre área seccional e gravidade da doença.


OBJECTIVE: To compare sonographic and surgical measured perimeters of the median nerve; to evaluate the diagnosis of carpal tunnel syndrome by median nerve cross-sectional area; to verify the association between cross-sectional area of the median nerve and carpal tunnel syndrome severity. MATERIALS AND METHODS: Thirty patients with established carpal tunnel syndrome were studied. Cross-sectional area and sonographic perimeter of the median nerve were measured. The correlation between clinical and sonographic findings and association with carpal tunnel syndrome severity were evaluated. Sonographic and surgical perimeters were compared. Clinical classification, surgical perimeter, cross-sectional area and sonographic perimeter of the median nerve were compared. Statistical analysis utilized paired samples t-test, Pearson's correlation, Bland-Altman's diagram, Kolmogorov-Smirnov's test, Welch's and Wilcoxon's tests. RESULTS: Five patients were excluded; 25 patients were studied; 60% of patients had moderated disease, and 60% presented cross-sectional area > 0.15 cm2. Distribution of surgical perimeter was not normal (p = 0.5); the sonographic perimeter distribution was normal (p = 0). There was a statistically significant difference between perimeters (paired samples t-test, p < 0.0001, confidence interval = 95%). Pearson's correlation corresponded to 0.3913. Bland-Altman diagram demonstrated higher values for surgical perimeters. Median nerve cross-sectional area > 0.09 cm2 was found in all the patients. CONCLUSION: No association was observed between median nerve sonographic and surgical perimeters. Median nerve cross-sectional area > 0.09 cm2 was valid for diagnosis of carpal tunnel syndrome. No association was observed between median nerve cross-sectional area and carpal tunnel syndrome severity.

ABSTRACT

A síndrome do túnel do carpo (STC) é patologia frequente em consultório de ortopedia, sendo a neuropatia compressiva mais comum e também a mais tratada por cirurgia. O diagnóstico da STC é eminentemente clínico, através da história clínica, exame físico (testes de Tinel, Phalen, Durkan) e exames complementares, mais especificamente estudos de neurocondução. Eventualmente, pode-se lançar mão de exames de ultrassonografia e ressonância magnética. O tratamento conservador é reservado para pacientes em que os sintomas são leves, pouco incapacitantes e melhoram com o uso de medicações anti-inflamatórias (esteroidais ou não esteroidais), fisioterapia e modificação dos hábitos de vida. O tratamento cirúrgico é o mais frequente, empregando diversas técnicas. O objetivo da cirurgia é descomprimir o canal do carpo e liberar o nervo mediano, por secção do ligamento transverso do carpo (LTC). O objetivo deste trabalho é comparar o tratamento cirúrgico da STC por mini-incisão transversa, proximal ao canal do carpo, com a incisão clássica, longitudinal, sobre o canal do carpo. A mini-incisão mostra-se uma opção menos invasiva e igualmente eficaz para o tratamento cirúrgico da STC, com menor morbidade do que a incisão longitudinal clássica.


Carpal tunnel syndrome (CTS) is the most common compressive neuropathy, a pathology frequently seen in orthopedic clinics and the neuropathy most often treated surgically. The diagnosis of CTS is made clinically, through a clinial history, physical examination (Tinel, Phalen, and Durkan tests) and complementary exams, and more specifically nerve conduction studies. Eventually, ultrasound scans and magnetic resonance imaging may be used. Conservative treatment is reserved for patients presenting with light symptoms, mild impairment and showing a good response to non-steroidal or steroidal anti-inflammatory drugs, physical therapy, and lifestyle changes. Surgical treatment is the most frequent, employing various techniques. The goal of the surgery is to decompress the carpal tunnel, and by sectioning the transverse carpal ligament, releasing the median nerve. This paper's objective is to compare the surgical treatment of CTS by means of two incisions: the first is the classic longitudinal incision over the transverse carpal ligament, and the second is a mini-incision at the wrist crease and near the proximal border of the ligament. The mini-incision technique is a less invasive and equally effective technique for the treatment of CTS, with less morbidity when compared to the classic longitudinal incision.

ABSTRACT

Introdução: a cada dia as lesões do plexo braquial(PB) estão se tornando mais comuns, devido grande quantidade de motociclistas, que são os mais atingidos. Objetivo: desenvolver um novo modelo de lesão parcial de plexo braquial. Método - Utilizados 40 ratos, divididos em grupo avulsão(GA) e grupo controle(GC). Anestesiados com pentobarbital, incisado paralelamente a clavícula direita, divulcionado até as raízes do PB. No GA realizada avulsão com uma pinça halsted das raízes de C8 e T1(tronco inferior) e no GC nenhum procedimento cirúrgico, somente controle da força. Eutanásia foi realizada 180 dias após. Para análise dos dados,realizado eletromiografia e o Grasping test em 3 oportunidades. Resultados: análise estatística com teste t pareado, com significância no Grasping test(P<0,001) e sem significância na EMG, tanto para latência como amplitude(P=0,031) com para amplitude(P=<0,001). Discussão: os acidentes de moto geralmente causam avulsão do PB, devido ao grande impacto. Na literatura foi encontrado este modelo, porém para o estudo da dor neuropática e não regeneração do nervo. Conclusão: com este trabalho constituímos um novo modelo de lesão parcial do plexo braquial.

ABSTRACT

Fibrolipomatous hamartoma is a rare benign neoplasm that in some cases is associated with macrodactylia. We describe a 31-year-old man who had a tissue enlargement in the wrist, second and third fingers of the left hand since infancy. At 23-years-old he began with continuous, progressive and high intensity pain that occurred more frequently at night, localized in the left hand. It was associated with paraesthesias and hypostesias predominantly at the fingers described above. Investigation with X-ray, ultrasonography, electrodiagnosis, magnetic resonance image of the left wrist and hand showed carpal tunnel syndrome with macrodactylia by fibrolipomatous hamartoma of the median nerve. The patient did not a have good response to clinical therapy, so he was submitted to a surgical decompression of the left carpal tunnel, and after three months of follow up is asymptomatic.


O hamartoma fibrolipomatoso é neoplasia benigna rara que em alguns casos esta associada com macrodactilia. Descrevemos o caso de homem de 31 anos que apresentava desde o nascimento aumento de volume em região de punho, segundo e terceiro quirodáctilos da mão esquerda. Aos 23 anos iniciou dor contínua, de forte intensidade, predominante no período noturno e de evolução progressiva em mão esquerda. Associada à dor havia hipoestesia e parestesias de predomínio nos segundo e terceiro quirodáctilos esquerdos. A investigação complementar com radiografia, ultrassonografia, estudo eletrofisiológico e ressonância magnética de mão e punho esquerdos confirmaram a suspeita de síndrome do túnel do carpo secundária a macrodactilia com hamartoma fibrolipomatoso do nervo mediano. O paciente foi submetido à descompressão cirúrgica do túnel do carpo esquerdo devido a ausência de resposta ao tratamento clínico e evoluiu com melhora dos sintomas em avaliação após três meses do procedimento.

ABSTRACT

Se estudiaron 30 pacientes con síndrome de túnel del caspo los cuales no respondieron en forma adecuada al manejo conservador, por lo cual fue necesario llevar a cabo una liberación quirúrgica del nervio mediano mediante sección abierta del ligamento transverso del carpo. Los pacientes fueron valorados en su postoperatorio mediato y tardío, evaluándose en cada uno de ellos dolor, sensibilidad y fuerza muscular, en base a lo cual se obtuvieron resultados excelentes en el 74 por ciento, resultados regulares en el 16 por ciento y malos resultados en el 10 por ciento, concluyéndose que el manejo quirúrgico empleado en este estudio es una adecuada opción de tratamiento en aquellos pacientes con síndrome de túnel del carpo en los que el tratamiento conservador no ofreció mejoría considerable

ABSTRACT

Lipofibroma ou hamartoma lipofibromatoso dos nervos é uma tumoraçäo rara, benigna, que afeta principalmente o nervo mediano e mais raramente o nervo ulnal. Raramente é observado no nervo radial ou nos membros inferiores. Observa-se infiltraçäo fibroadiposa difusa no interstício do nervo, dissociando os fascículos, sem invadir o tecido nervoso. O quadro clínico é de síndrome compressiva (síndrome do túnel do carpo ou do canal de Guyon). O tratamento é sintomático, isto é, descompressäo do nervo nos túneis osteofibrosos. Säo apresentados dois casos: um de lipofibroma do nervo mediano com seis meses de evoluçäo pós-operatória e outro do nervo ulnar operado há 17 anos, estando ambos assintomáticos e sem sinais de progressäo da tumoraçäo

ABSTRACT

Relata-se o caso de paciente com síndrome do túnel do carpo (STC) de longa evoluçäo que exibia mal perfurante palmar. Submetida a cirurgia descompressiva (epineurólise microcirúrgica do nervo mediano e tendossinovectomia) houve rápido desaparecimento das lesöes cutâneas embora o déficit sensitivo e as alteraçöes aos testes neurofisiológicos näo revelassem melhora significativa. Acreditamos que estes achados falem contra a hipótese de que as graves alteraçöes tróficas ocasionalmente encontradas nestes enfermos sejam consequentes ao severo déficit sensitivo. Tais anormalidades devem ser devidas à disfunçäo das fibras simpáticas do nervo mediano

ABSTRACT

Nerve pedicle grafts in the forearm were performed on six patients with Volkmann's Ischaemic contracture with massive damage of both median and ulnar nerves. The operation was performed in two stages, in the first stage, flexor pronator release was done and the distal ends of the proximal segments of the median and ulnar nerves were sutured together and the ulnar nerves were incompletely sectioned high in the axilla. Six weeks later, the ulnar nerve was transposed distally and sutured to the healthy distal segment of the median nerve proximal to the wrist joint. All patients regained a reasonable motor and sensory recovery in the area supplied by the median nerve and sudomotor recovery was good. Trophic ulcers on the tip of medial three fingers have markedly decreased. The patients can manage variable independent activities of daily life. This procedure definitely should have a place in situation when the median and ulnar nerves have been damaged beyond hope of recovery

ABSTRACT

This study describes thirty-four cases of median and ulnar nerve injuries. Of these, ten cases had primary repair, eleven had delayed repair, seven were grafted and six patients in whom the lesion was in-continuity were treated by neurolysis. The average age was 32 years [range 14 to 45 years]. The average follow-up period was 4 years [range 1.5 to 5 years]. There were five excellent results, two after primary, one after graft and two after neurolysis. Seventeen were good, seven were fair and five were poor. The excellent results were found in younger aged patients
