La fractura-luxación de Monteggia.Tratamiento y pronóstico. A propósito de 35 casos.

Estudio retrospectivo de 35 casos de fractura-luxación de Monteggia tratados entre los años 1990 y 2003. Los resultados fueron satisfactorios en 29 pacientes, regulares en 4 casos y malos en los 2 restantes. Conclusiones: El tratamiento de esta lesión debe ser ortopédico en pacientes en edad infantil. En los adultos, por el contrario, el tratamiento debe ser quirúrgico y consistir en una osteosíntesis estable de la fractura del cúbito, a poder ser con una placa tipo DCP. La reducción de la luxación de la cabeza del radio debe intentarse siempre de forma ortopédica pues los resultados así conseguidos son mejores. Si no es posible, puede intentarse la reducción abierta, evitando siempre que sea posible la exéresis de la cabeza radial. Por otra parte, el diagnóstico y el tratamiento deben realizarse lo más precozmente posible para poder obtener un buen resultado funcional.We present a retrospective study of 35 cases of Monteggia fracture-dislocation treated between the year 1990 and 2003. The results were satisfactory in 29 patients, intermediate in 4 cases and poor in the 2 remaining ones. Conclusions: Treatment of this injury must be orthopaedic in childhood. In the adults, on the contrary, the treatment must be surgical and to consist of a stable osteosynthesis of the fracture of the ulna with a DCP type plate. Reduction of the head of the radius dislocation must be always tried by orthopaedic methods since the results like that obtained are better. If it is not possible, the open reduction can be tried, avoiding providing that there is possible the resection of the radial head. On the other hand, diagnosis and treatment must fulfil early to be able to obtain a good functional result

Reducción cerrada y osteosíntesis con agujas percutáneas en las fracturas del radio distal

Se presentan 185 casos de fractura compleja del radio distal tratados con reducción ortopédica y estabilización con agujas de Kirschner introducidas de forma percutánea y asociadas a vendaje escayolado antebraquial. Los resultados funcionales finales fueron buenos o excelentes en 156 de los 185 casos (84,3%). Teniendo en cuenta los resultados, consideramos que el método es sencillo, útil y económico y debe valorarse su uso en la mayoría de las fracturas del radio distal.We report 185 cases of distal radius fractures treated by closed reduction and percutaneous Kirschner wire fixation. Final functional results were good or excellent in 156 of the 185 cases (84,3%). In view of the results, we think that the method is simple, useful and cheap, and must value its use in the majority of the distal radius fractures

El síndrome de nail-patella: presentación de 5 casos

Se presentan 5 casos de síndrome de nail-patella de 2 familias distintas. En todos ellos eran evidentes los rasgos clínicos característicos de la enfermedad. Tres de los pacientes presentaban luxación recidivante de rótula con importante repercusión funcional. Fueron intervenidos quirúrgicamente con unos buenos resultados funcionales. Las alteraciones en los codos no provocaban trastornos funcionales importantes y no precisaron tratamiento quirúrgico.Five cases of nail-patella syndrome of 2 different families are presented. In all of them there were evident the clinical features typical of the disease. Three of the patients presented recurrent dislocation of patella with important functional repercussion. They were managed surgically with a good functional result. The troubles in the elbows did not provoke important functional disorder and they did not need surgical treatmen

Fracturas complejas del radio distal: tratamiento quirúrgico de las fracturas tipo C2

Se presentan 73 casos de fractura de radio distal tipo C2 tratadas en nuestro servicio. Se utilizó como método de osteosíntesis una placa palmar en 3 casos, agujas de Kirschner en 38 casos, fijadores externos en 30 y fijador externo + agujas en 2 casos. Los mejores resultados se obtuvieron en los grupos de casos tratados con placa palmar y con agujas + fijador externo. El fijador externo, aplicado de forma aislada, que "a priori" era el mejor sistema de tratamiento, ha resultado al final ser el procedimiento que se ha visto acompañado de una mayor proporción de secuelas clínicas y consolidaciones viciosas.A total of 73 cases of C2 type fracture of the distal radius treated in our Department are presented. A volar pla- te was used as fixation method in 3 cases, Kirschner wire in 38 cases, external fixator in 30 cases, and external fixator plus Kirschner wire in 2 cases. The best results were obtai- ned in the groups of cases treated with a volar plate and ex- ternal fixator associated with Kirschner wire. The isolated external fixator, that at first was the best system of treatment, has turned out to be the procedure that has been accompa- nied by a greater incidence of clinical sequels and vicious consolidations

Tratamiento quirúrgico de las fracturas del radio distal en pacientes jóvenes

Se presentan 118 casos de fractura de radio distal ocurridas en pacientes jóvenes (menores de 40 años) tratadas en nuestro Servicio entre los años 1992 y 2004. Se utilizó como método de osteosíntesis una placa palmar en 26 casos, agujas de Kirschner percutáneas en 60 casos asociadas a vendaje escayolado, fijadores externos en 25 y fijador externo + agujas en los 7 casos restantes. Tras la revisión de los resultados, hemos observado los mejores resultados en el grupo de casos tratados con placa volar y una alta incidencia de secuelas clínicas y consolidaciones viciosas entre los pacientes tratados con fijador externo.A total of 118 cases of fracture of the distal radius in young patients (smaller of 40-year-old) treated in our Department between years 1992 and 2004 are presented.

Robot Trajectories Comparison: A Statistical Approach

The task of planning a collision-free trajectory from a start to a goal position is fundamental for an autonomous mobile robot. Although path planning has been extensively investigated since the beginning of robotics, there is no agreement on how to measure the performance of a motion algorithm. This paper presents a new approach to perform robot trajectories comparison that could be applied to any kind of trajectories and in both simulated and real environments. Given an initial set of features, it automatically selects the most significant ones and performs a statistical comparison using them. Additionally, a graphical data visualization named polygraph which helps to better understand the obtained results is provided. The proposed method has been applied, as an example, to compare two different motion planners, FM2 and WaveFront, using different environments, robots, and local planners

Indigenous school education as contested spaces: the Brazilian experience in São Paulo and Mato Grosso do Sul

Indigenous schools are spaces for the convergence of different worldviews and to demonstrate how the creativity of each ethnic group challenges exogenous and established concepts and methodologies. This article examines main trends and pending gaps related to indigenous education in Brazil between the years 2007 and 2019. Issues such as the characterisation of indigenous schools, teachers and students are analysed, with a focus on the evolution of the number of students enrolled, infrastructure, language and pedagogic approaches. The analysis is focused on the states of Mato Grosso do Sul, which has a large indigenous population and an economy based on export-oriented agribusiness, and São Paulo, the main economic, demographic and political centre of Brazil with a much smaller indigenous population. The results demonstrate concrete improvements, especially the expansion of the number of schools and the student population. A growing number of schools are now dedicated to serve indigenous populations and make use of specific teaching material (although this material is of uneven quality). However, many problems remain unresolved, including threats to funding and uncertain administrative support from public authorities, a situation that has been aggravated in recent years with the growing adoption of elitist, anti-indigenous government policies
