ABSTRACT

ABSTRACT Introduction The extreme lateral approach has been widely used for the treatment of degenerative diseases. The objective of this study is to present a minimally invasive extreme lateral approach for the treatment of metastatic lesions in the lumbar spine without the use of the evoked potential exam (MEP). Methods Two patients with spinal metastases and indication for surgery via the anterior approach were treated in a cancer referral center in Brazil. They were placed in right lateral decubitus, and an oblique incision was made, exposing the psoas muscle. The anterior approach permitted the release of the psoas muscle from vertebral body and disc, without the need for MEP. Conclusions When cancer cure is no longer possible, a minimally invasive extreme lateral approach to treat tumor metastases in the lumbar spine is a viable option, with short hospitalization time and low morbidity. The dislocation of the psoas muscle avoids the use of the transpsoas approach, which requires MEP equipment and a trained physician. Clinical studies are needed to extend these benefits to oncological patients who have treatment options for their primary disease. Level of Evidence IV; Case series.


RESUMO Introdução A técnica extremo-lateral já vem sendo amplamente usada no tratamento de doenças degenerativas fazendo com que o objetivo deste trabalho seja de apresentar a técnica extremo-lateral minimamente invasiva para o tratamento de metástases na coluna lombar, sem a necessidade do potencial evocado motor (MEP). Método Dois pacientes com metástases em coluna com indicação para cirurgia pelo acesso anterior foram tratados em um centro de referência no Brasil. Eles foram posicionados em decúbito lateral direito e uma incisão oblíqua foi feita, expondo o músculo psoas. Pela via anterior, foi possível descolar as fibras do músculo psoas do corpo vertebral e disco, sem a ajuda do MEP. Conclusão Quando a cura do câncer não é possível, o acesso extremo lateral por cirurgia minimamente invasiva é uma opção viável no tratamento de metástases tumorais na coluna lombar, com hospitalização curta e baixa morbidade. O descolamento do psoas evita o uso da via transpsoas, que exigiria a assistência com equipamento de MEP e profissional treinado para operá-lo. Estudos clínicos são necessários para que esses benefícios sejam estendidos a pacientes com câncer, para que ainda haja opção de tratamento para a doença primária. Nível de Evidência IV; Série de casos.

ABSTRACT

OBJECTIVE: There are few data on patient satisfaction with surgery for the correction of neuromuscular scoliosis or on the correlation between patient satisfaction and the degree of curve correction achieved by surgery. Our aim was to determine the correlations between both patient satisfaction and perception of quality of life and the degree of curve correction. METHODS: We interviewed 18 patients and administered a questionnaire that collected social and economic data and information about functional ability, comorbidities and satisfaction. Statistical analysis was performed using chi-square tests, Pearson correlation and paired t-tests. RESULTS: The mean correction achieved was 42.8%, i.e., 34.17 degrees. Early and late complication rates were low (11.1% each). Almost all of the patients (94.4%) were satisfied with the surgery, and expectations were met for 61.1% of them. Quality of life and aesthetics were improved in 83.4% and 94.4% of cases, respectively. No correlation was found between satisfaction and degree of correction. CONCLUSION: Our surgical results are similar to those of other studies with respect to the degree of correction and patient satisfaction. The disparity between satisfaction and fulfillment of expectations may be due to unrealistic initial expectations or misunderstanding of the objective of surgery. Our findings corroborate the hypothesis that satisfaction is multifactorial and not restricted to a quantitative goal. The satisfaction of patients who undergo operation for neuromuscular scoliosis does not depend directly on the degree of deformity correction. The relationship between satisfaction and the success of the correction procedure is complex and multifactorial.

ABSTRACT

ABSTRACT Objective: Tomographic and anatomic analysis of cervical vertebrae in children from 0 to 12 years of age to verify the possibility of utilization of lateral mass screws. Methods: Twenty-five cervical spine tomographies of children between 0 and 12 years of age, admitted to the emergency room of Hospital das Clínicas of São Paulo were retrospectively analyzed. The following distances were measured: width and length of the lateral masses in the axial section; width and height in the coronal section; height, length and diagonal diameter in the sagittal section. The variables studied were correlated with age and sex and submitted to statistical analysis. Results: The analysis of tomographic measurements of 20 patients showed a correlation between age and dimensions of the lateral mass, which were higher after 6 years of age. In relation to sex, greater measures were observed in males in all axes. With regard to the passage of the screws, we only had 22 masses (11%) that prevented their use. However, when stratified by age, we noticed that no patients had restrictions on the use of the lateral mass screw after the age of 6. Conclusion: This study analyzed the measurements of 200 lateral masses, making it possible to infer that there is an increase of dimensions with age and in males. Through the data, it was possible to affirm that in this sample, considering the implants available in the market, the lateral mass screws could be used in 89% of the lateral masses.


RESUMO Objetivo: Análise tomográfica e anatômica das vértebras cervicais em crianças de zero a doze anos de idade para verificar a possibilidade de passagem de parafuso de massa lateral. Métodos: Foram analisadas retrospectivamente 25 tomografias de coluna cervical de crianças entre 0 e 12 anos de idade, admitidas no pronto socorro do Hospital das Clínicas de São Paulo. Foram aferidas as seguintes medidas: largura e comprimento das massas laterais no corte axial; largura e altura no corte coronal; altura, comprimento e diâmetro diagonal no corte sagital. As variáveis estudadas foram correlacionadas com a idade e o sexo dos indivíduos e submetidas a análise estatística. Resultados: Por meio da análise de medidas tomográficas de 20 pacientes, foi verificada a correlação entre idade e dimensões das massas laterais, sendo estas maiores a partir dos 6 anos. Já em relação ao sexo, foram verificadas medidas maiores no sexo masculino em todos os eixos. Com relação à passagem dos parafusos, tivemos apenas 22 massas (11%) com impossibilidade de uso. Porém, quando estratificados pela idade, notamos não haver pacientes com impedimento para uso do parafuso de massa lateral após os 6 anos. Conclusão: O estudo analisou as medidas de 200 massas laterais, possibilitando inferir que existe aumento das suas dimensões com a idade e no sexo masculino. Através dos dados, foi possível afirmar que nesta amostra, considerando-se os implantes disponíveis no mercado, o parafuso de massa lateral poderia ser utilizado em 89% das massas laterais.


RESUMEN Objetivo: Análisis tomográfico y anatómico de las vértebras cervicales en niños de hasta doce años de edad, para comprobar la posibilidad de pasaje de tornillos de masa lateral. Métodos: Se analizaron retrospectivamente 25 tomografías computarizadas de la columna cervical de niños entre 0 y 12 años de edad, ingresados en el servicio de urgencias del Hospital das Clínicas de São Paulo. Se tomaron las siguientes medidas: anchura y longitud de las masas laterales en corte axial; anchura y altura del corte coronal; altura, longitud y diámetro diagonal en el corte sagital. Las variables se correlacionaron con la edad y el sexo de los individuos y se sometieron a análisis estadístico. Resultados: Mediante el análisis de las mediciones tomográficas de 20 pacientes, se observó la correlación entre la edad y las dimensiones de las masas laterales, que son más grandes a partir de los 6 años de edad. En relación con el sexo, se observaron medidas más altas en los hombres en todos los ejes. En cuanto al paso de los tornillos, encontramos sólo 22 masas (11%) que impidieron su uso. Sin embargo, cuando se estratificó por edad, observamos que no había ningún impedimento para el uso de tornillo de masa lateral después de 6 años de edad. Conclusión: El estudio examinó las medidas de 200 masas laterales, por lo que es posible inferir que hay un aumento de tamaño con la edad y en el sexo masculino. De estos datos, fue posible afirmar que en esta muestra, teniendo en cuenta los implantes disponibles en el mercado, el tornillo de masa lateral podría ser utilizado en el 89% de las masas laterales.
