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

Esse estudo tem por objetivo avaliar a capacidade funcional da mão das pessoas atingidas pela hanseníase na realização das atividades básicas e instrumentais da vida diária. A amostra foi constituída por 50 pacientes, maiores de 18 anos, que estavam sendo acompanhados no ambulatório do Instituto Lauro de Souza Lima. Para avaliação das características sociodemográficas e clínicas foi elaborado um questionário próprio. As dificuldades manuais para realizar atividades nas áreas de vestuário, alimentação, higiene pessoal, cuidados com a casa, escrita e outros foram avaliados por meio da Avaliação Funcional das Mãos em Hanseníase. Os resultados demonstram que em todas as atividades houve algum grau de dificuldade, porém, a maioria dos pacientes as realiza com independência. As atividades consideradas mais difíceis de serem executadas pelos pacientes com garra ulnar foram: pegar objetos pequenos em superfície plana, abrir/fechar fecho de corrente e cortar unhas. Na população de pacientes com garra ulnar/mediano foram: pegar objetos pequenos em superfície plana, abotoar/desabotoar, dar laço/ amarrar cadarço e abrir/fechar fecho de corrente. As atividades são realizadas com algum grau de dificuldade, porém, com independência pela maioria dos indivíduos que tem ou tiveram hanseníase e apresentam deformidades visíveis. Muitas dessas dificuldades podem ser minimizadas por meio de transferências tendinosas ou pela indicação, confecção e uso de tecnologia assistiva(AU).


This study aims to assess the functional capacity of the hand of people affected by leprosy in carrying out basic and instrumental activities of daily living. The sample consisted of 50 patients, aged over 18, who were being followed up at the outpatient clinic of the Instituto Lauro de Souza Lima. A questionnaire was developed to assess sociodemographic and clinical characteristics. Manual difficulties in carrying out activities in the areas of clothing, food, personal hygiene, home care, writing and others were assessed through the Functional Hand Assessment in Leprosy. The results show that in all activities there was some degree of difficulty, however, most patients perform them independently. The activities considered most difficult to be performed by patients with an ulnar claw were: picking up small objects on a flat surface, opening / closing the chain clasp and cutting nails. In the population of patients with an ulnar / median claw were: picking up small objects on a flat surface, buttoning / unbuttoning, looping / tying shoelaces and opening / closing chain fastening. The activities are performed with some degree of difficulty, however, independently by the majority of individuals who have or have had leprosy and have visible deformities. Many of these difficulties can be minimized by means of tendon transfers or by the indication, preparation and use of assistive technology(AU).

ABSTRACT

A avaliação funcional da sensibilidade é essencial para analisar o estado, recuperação, e efetividade do programa de tratamento em pacientes que sofreram perdas decorrentes de deficiência motora e/ou sensitiva, após lesões nervosas periféricas. Estas lesões geram a interrupção das sensações ocasionando a perda da sensibilidade e uma significante perda funcional da mão. Objetivo: O objetivo deste estudo foi correlacionar o teste funcional Pick-Up de Moberg com o teste de limiar sensitivo Estesiômetro SORRI® na reconstrução do nervo mediano. Métodos: Foram analisados 14 homens com idade entre 18 e 40 anos que sofreram ferimento corto-contuso na região volar do punho e tratamento cirúrgico há pelo menos um ano de pós-operatório. Foram utilizados para a avaliação da sensibilidade cutânea o Estesiômetro SORRI® e o teste Pick-Up de Moberg modificado, no qual a avaliação foi dividida em duas fases, olhos abertos e fechados, ambas realizadas com a mão dominante e não dominante, e em duas etapas com diferentes avaliadores, sendo repetidas três vezes em cada mão. A sequência dos avaliadores foi sorteada e mantida durante toda a avaliação. Na análise dos dados foi utilizado o coeficiente de Pearson e aplicado o teste não-paramétrico de Mann-Whitney com o nível de significância ? = 0,05. Resultados: A média da idade foi de 27,14 anos (±6,43), com maior frequência entre 21 a 30 anos sendo que 64% apresentaram lesão na mão dominante. O coeficiente de Pearson (r) entre o Estesiômetro e o Pick-Up foi entre 0,5 e 0,7, com p-valor <0,05. Os intervalos de confiança e p-valores dos testes de Mann-Whitney não indicaram diferenças estatisticamente significantes. Conclusão: Apesar do teste Pick-Up de Moberg não possuir medidas padronizadas, na amostra estudada pode-se concluir que existe correlação entre o teste funcional e o teste de limiar sensitivo. Novos estudos são necessários para a validação e confiabilidade de ambos os métodos.


Functional assessment of sensitivity is essential to analyzing the status, recovery, and effectiveness of the treatment program for patients who have suffered losses due to physical and / or sensory disability after peripheral nerve injuries. Such losses of sensation lead to a significant loss of hand function. Objective: The purpose of the present study was to establish a correlation between functional and sensory threshold tests after a peripheral nerve lesion in the hand. Methods: Fourteen men aged 18 to 40 years, who had bruises and cut injuries at the volar region of the wrist resulting in median nerve lesion, were selected for study. All the subjects were at least 1-year post-surgery. An esthesiometer SORRI® and a modified Moberg pick-up test were used. The test was divided into two phases, one with eyes open and the other with eyes closed. Also, the same test was performed by two different examiners. It was a "blinded" test that was performed three times, being repeated by the examiners according to a random sequence kept during the entire evaluation. Mean age and standard deviation were obtained during analysis in which Pearson's coefficient was calculated and the non-parametric Mann-Whitney test was applied at 5% significance. Results: The mean age was 27.14 years with a standard deviation of 6.43 years, with the lesions being more frequently seen in men aged 21 to 30 years. Also, 64% of the cases involved lesion of the dominant hand. Pearson's coefficient (r) regarding the correlation between sensory threshold test and Moberg pick-up test ranged from 0.5 to 0.7, which was statistically significant. Confidence intervals and p-values obtained from the Mann-Whitney test showed no statistically significant differences. Conclusion: One can conclude, therefore, that despite lacking standardized measures, the Moberg pick-up test correlated with the functional test. However, further studies are needed to support validation and reliability of the two methods.

ABSTRACT

O uso da reabilitação virtual através do video game visa simulação de situações reais; percebe-se que o uso desta, afasta o paciente do foco da dor ou do incomodo; melhora na funcionalidade dos membros acometidos e o leva a retomar as atividades nas áreas de desempenho ocupacional. Este estudo teve como objetivo verificar o uso da reabilitação virtual, como recurso terapêutico ocupacional, em um paciente com lesão alta dos nervos mediano e ulnar, bem como descrever e comparar os graus da amplitude de movimento das articulações do membro lesado. Trata- se de uma pesquisa do tipo longitudinal com um paciente de 09 anos de idade, sexo masculino, diagnosticado com lesão nervosa, na Clínica Escola de Terapia Ocupacional da Universidade Potiguar, no período de maio a setembro de 2010. Nos 13 encontros, foram utilizados televisão, o videogame Nintendo® Wii e quatro jogos e um goniômetro como instrumentos de intervenção e coleta de dados. Na reavaliação, observou-se a movimentação ativa e o aumento da amplitude de movimento em todas as articulações medidas: cotovelo em flexão e extensão; antebraço em pronação e supinação; punho em flexão, extensão, desvio ulnar e desvio radial; polegar em flexão de metacarpofalangiana, flexão interfalangiana, abdução e estágio III de oponência (Kapangji); II, III, IV e V quirodátilos. Os metacarpos apresentaram ganhos em flexão e extensão. Os resultados desse estudo evidenciaram a eficácia do videogame, comprovado através da avaliação goniométrica. O indivíduo estudado voltou a realizar as atividades de vida diária de forma independente e retornou as suas atividades esportivas de forma competitiva.


The use of virtual rehabilitation with video games aims to simulate real situations. It has been observed that the use of video games as a rehabilitation tool allows the patient to focus on something other than the pain or discomfort. It improves functionality of affected limbs, and helps the patient to resume activities involving occupational performance. The intent of this study was to verify the application of virtual rehabilitation as a resource for occupational therapy for a patient with high median and high ulnar nerve injuries, and to describe and compare the levels of range of motion of the injured limb joints. This was a longitudinal survey with a 9 years old patient, male, diagnosed with nerve damage at the Potiguar University School of Occupational Therapy Clinic. The survey was carried out from May to September of 2010. Throughout the 13 sessions, a television and a Nintendo ® Wii video game (with four games) were used as intervention tools, and a goniometer was used for collecting data. During reassessment, active movement and increased range of motion in all joints assessed were observed: elbow flexion and extension; forearm pronation and supination; wrist flexion, extension, radio and ulnar deviation; thumb metacarpophalangeal flexion, interphalangeal flexion, abduction and opponency at stage III (Kapandji); II, III, IV and V fingers. The metacarpals presented improvements in flexion and extension. The results showed the effectiveness of video games as evidenced by goniometric evaluation. The patient studied regained the ability to perform activities of daily living independently and to play sports competitively.

ABSTRACT

OBJETIVO: elaborar um questionário de avaliação funcional para analisar as dificuldades manuais encontradas na realização de atividades cotidianas de indivíduos ocidentais adultos com lesão dos nervos ulnar, mediano ou radial.MÉTODO: foi realizada entrevista com 50 pessoas, idade entre 21 e 65 anos, portadoras de lesão nos nervos ulnar, mediano ou radial para identificar as dificuldades manuais ao realizar as tarefas cotidianas. Em seguida, seis cirurgiões de mão e nove terapeutas de mão, analisaram as tarefas listadas pelos entrevistados e as classificaram em níveis de importância para uma avaliação funcional das mãos. Posteriormente, o questionário foi elaborado baseado nessa classificação.RESULTADOS: o "Questionário de avaliação da mão com lesão de nervo" é constituído por 30 questões objetivas divididas em domínios de tarefas (vestuário, alimentação, higiene pessoal, tarefas domésticas, escrita, uso de computador e atividades diversas). As respostas são atribuídas de acordo com o grau de dificuldade na realização das tarefas listadas no instrumento. O questionário foi respondido por 32 pessoas com idade entre 18 e 65 anos apresentando sequela de hanseníase. O cálculo do alfa de Cronbach foi utilizado para avaliar a confiabilidade do instrumento. Após a remoção de duas questões relacionadas ao uso de computador, o resultado do alfa de Cronbach aumentou para 0,90.CONCLUSÃO: o "Questionário de avaliação da mão com lesão de nervo" apresenta alta consistência interna. Além disso, é conciso, de fácil preenchimento não necessitando a presença de profissional especializado para sua aplicação e permite a verificação do nível de independência do indivíduo com lesão de nervo periférico na mão na realização de suas tarefas habituais.

ABSTRACT

The objective of this study was to evaluate morphological changes of the median nerve in patients with carpal tunnel syndrome (CTS) and healthy controls, to correlate the MRI findings of wrists. This study compared not only morphological changes of the median nerve and also displayed descriptively structures in carpal tunnel between patients diagnosed with idopathic CTS and healthy controls. Our study involved 60 hand, 30 of hand were evaluated diagnosed with idiopathic CTS and 30 hand as healthy controls bilaterally. Two provocative tests (Phalen's and Tinel's test) were performed on each hand for both the patient group (60 wrist) and the control group (60 wrist). With regard to Phalen and Tinel's test results, 24 and 26 wrists were excluded from patient and control groups respectively. Totally 70 wrists were evaluated, and in terms of cross-sectional area of median nerve at the level of distal radio-ulnar joint, pisiform bone and the hook of hamate bone by MRI in the patient and control groups. In addition to evaluation of cross-sectional area of median nerve, we determined signal intensity of wrists and different localization of the median nerve in the carpal tunnel. Cross-sectional area of the median nerve measured by wrist magnetic resonance at the level of metacarpal bones and signal intensity of wrists may be considered as a valuable indicator to determine patients referred with idiopathic CTS.


El objetivo de este estudio fue evaluar los cambios morfológicos del nervio mediano en pacientes con síndrome del túnel carpiano (STC) y controles sanos, para correlacionar los hallazgos de las RM de muñeca. Este estudio comparó no sólo los cambios morfológicos del nervio mediano, también se muestran en forma descriptiva estructuras del túnel carpiano entre los pacientes diagnosticados con STC idiopatico y controles sanos. Nuestro estudio incluyó 60 manos, 30 manos fueron evaluados con diagnóstico de STC idiopático y 30 manos como controles sanos, bilateralmente. Dos pruebas de provocación (prueba de Phalen y prueba de Tinel) se realizaron en cada mano para el grupo de pacientes (60 muñecas) y el grupo control (60 muñecas). En lo que respecta a los resultados de prueba de Phalen y prueba de Tinel, 24 y 26 muñecas fueron excluidas del grupo paciente y grupo control respectivamente. En total 70 muñecas fueron evaluadas, en términos de la sección transversal del área del nervio mediano a nivel de la articulación radio-ulnar distal, el hueso pisiforme y el hamulus del hueso hamate por medio de resonancia magnética en gruposs paciente y control. Además de la evaluación de la sección del área del nervio mediano, se determinó la intensidad de la señal de la muñeca y las diferentes localizaciones del nervio mediano en el túnel carpiano. La sección transversal del área del nervio mediano medida por medio de resonancia magnética de muñeca a nivel de los huesos metacarpianos y la intensidad de la señal de las muñecas pueden ser considerados como un valioso indicador al evaluar pacientes referidos con STC idiopático.

ABSTRACT

This study reports the results of 87 operations performed on nerves of the upper extremities of 87 patients during the period of 5 years from 2000-2005 in Mansoura University hospital and Emergency Hospital. Among them there were 84 males and 3 females, age ranged from 5 - 53 years. There were 27 patients with isolated median nerve injury, 33 with isolated ulnar nerve injury, 12 with isolated radial nerve injury and 15 patients with combined median and ulnar nerve injury. All patients were treated with nerve exploration within 1 hour, 7 months after combined injury and were followed-up for 3 months - 2 years. There were 77 nerve lesions not in continuity [74 needed suture repair and 3 needed sural nerve graft repair], while 25 nerve lesions where in continuity [9 partial lesions needed neurolysis and 16 complete lesions needed neuroma excision and suture repair]. Analysis of the outcome of surgical treatment was performed with respect to the following parameters: period between the injury and operation, patient age, type of injured nerve, level of injury and type of surgical intervention. Overall significant outcome [>/= 3 Lousiana State University Health Science [LSUHS] grade] was obtained in 67.5% [radial nerve 75%, ulnar nerve 64% and median nerve 71%]. Significant outcome according to the level of the injury were 51% arm, 69% forearm and elbow and 82% wrist. According to the type of intervention and lesion categories, lesions not in continuity had a significant outcome 61% [primary suture repair 75%, secondary suture repair 61%, while graft repair was 0%]. Lesions in continuity had a significant outcome 88% [partial lesions underwent neurolysis 100%, while complete lesions underwent surture repair 81%, cut injuries 79% and crushed injuries 59%]. The most favourable outcome was obtained with lesions that result in partial lesion in continuity

ABSTRACT

Pathomimia,or factitious disorders, are characterized by producing symptoms voluntarily with the intention of playing the role of the patient. Inspite of being considered as a psychiatric disorder, pathomimia is often encountered in the daily professional life of doctors without being recognized or diagnosed. There are various clinical aspects of pathomimia. The items that decide the orientation of the diagnosis are essentially the uncommon and odd expression of the reported symptoms. A capricious evolution as well as the multiplicity of the past medical cases. We report a group of five patients who were followed and treated between the years 2000 and 2003. This group was composed of three men and two women with an average age of 30 years. In three cases, we found the notion of skin injury. In one case, we noted a median nerve lesion in the elbow and once in the right upper member. The evolution was performed towards recidives of the initial symptomatology with more or less long periods of improvements

ABSTRACT

La lepra es siempre una enfermedad cutánea y nerviosa periférica. Existen formas clínicas bien definidas localizadas en los troncos nerviosos: cara, cuello, miembros, dando la clásica mononeuritis múltiple. El primer lugar le corresponde al cubital, seguido por el ciático poplíteo externo. Según cifras estadísticas y nuestra propia experiencia hay predominancia para el cubital en la gotera oleacraneana respecto de la palma y en la cabeza del peroné para el ciático poplíteo externo respecto del hueco poplíteo. El engrosamiento nervioso es facilmente palpable y aún visible. Se hace la descripción anatómica y funcional siguiendo a Guy Lazorthes y la interpretación de la biomecánica en base a los estudios y aportes de Manzi, R.O y colaboradores, con las consecuencias ulcerotróficas del disbalance muscular. El panadizo analgésico y el mal perforante plantar son dos cuadros habituales en la lepra. No así el absceso del nervio y el síndrome hombro-mano-dedos. Se citan referencias en nuestro país. Nuestro material es recopilado del Hospital Perrando y servicio de Dermatología de Resistencia. Se observó predominancia de formas múltiples además de formas lepromatosas. En la fisiopatogenia se hace referencia al estado de hibernación en que vive el bacilo en la vaina de Schwann, ya que éste vive años a cambio del histiocito que no vive más de una semana. Como resultado de un conflicto local donde intervienen fenómenos tisulares, inmunológicos y circulatorios, se producen, de acuerdo a la capacidad del huésped, las distintas formas de lepra: tuberculoide, lepromatosa, dimorfa e incaracterística. Se describe otra forma que es la neuritis autoinmune secundaria de Languillon y Carayon como expresión de pérdida de alergia tisular. La isquemia del nervio es la condicionante de la lesión neural que lleva a la esclerosis. La liberación del tronco del canal por sección de fibras de inserción muscular y la neurolisis con epineurotomía son propuestas como los medios más útiles para la cirugía, cuando se han agotado los recursos médicos conservadores

ABSTRACT

O presente estudo é uma análise dos resultados obtidos em 71 pacientes da Clínica de Fraturas e Ortopedia XV com lesäo dos nervos mediano e ulnar, que foram tratados, de janeiro de 1975 a julho de 1986 (11,5 anos), com neurorrafia ou enxerto, conforme cada caso assim o exigisse, pela técnica de sutura epineural externa ou epineural externa e interna. O tempo de seguimento médio foi de 5,6 anos, com um mínimo de dois anos, utilizando para avaliaçäo os critérios internacionais. Nos 71 pacientes foram efetuadas 55 neurorrafias e 37 enxertos, sendo que, para a avaliaçäo dos resultados, as lesöes foram divididas em altas, quando ao nível do braço e cotovelo; intermediárias, quando no antebraço; e baixas, quando no punho. Dessa forma, efetuou-se uma comparaçäo entre os nossos resultados e os resultados de outros autores. Foram também estabelecidos dois grupos padronizados de pacientes que tinham tempo de seguimento entre 2/3 anos e acima de cinco anos, pretendendo-se, com isso, verificar quanto tempo, após o tratamento, devemos aguardar para que os resultados motor e sensitivo estejam bem definidos. Concluiu-se näo haver diferença estatisticamente significativa entre os dois grupos. Da mesma maneira, comparam-se dois grupos de pacientes padronizados que haviam sido submetidos a neurorrafia ou enxerto. Também näo foram notadas diferenças estatisticamente significativas entre pacientes operados com uma ou outra técnica
