ABSTRACT

Objetivo: La reducción y fijación de la fractura de la cabeza del radio tipo MasonII asistida por artroscopia es una técnica válida que proporciona buenos resultados. El objetivo de este estudio es llamar la atención sobre la utilidad de la localización de la fractura en la cabeza del radio en cuadrantes definidos con respecto a la tuberosidad bicipital mediante la TC. Ello ayudaría a planificar la posición del antebrazo óptima para acceder a cada cuadrante y prever las dificultades específicas de cada uno. Material y método: Se ha procedido a la disección de 4 especímenes de cadáver criopreservado. Hemos dividido la cabeza del radio en 4 cuadrantes con respecto a la tuberosidad bicipital objetivando el cambio de posición en pronación y en supinación máxima con respecto a la cavidad sigmoidea menor y a las estructuras neurovasculares. Resultados: La cabeza del radio se desplaza con la pronosupinación, por lo que existen áreas de convergencia entre los distintos cuadrantes. El cuadrante1 se aborda en supinación por un portal anteromedial. El cuadrante2 se aborda en pronación máxima mediante un portal lateral. El cuadrante3 se puede abordar a través de portales laterales, con el antebrazo en posición neutra y en pronación. El cuadrante4 es accesible con el antebrazo en posición neutra y en supinación a través de un portal lateral. Conclusiones: Según la localización de la fractura en la cabeza del radio con respecto a la tuberosidad bicipital, necesitaremos acceder por un portal artroscópico determinado, siendo los cuadrantes mediales (anteromedial y posteromedial) los más exigentes técnicamente


Objective: The management of MasonII fracture pattern assisted by arthroscopy is a valid technique that provides good results. The objective of this study was to draw attention to the usefulness of the location of the fracture in the head of the radius in defined quadrants with respect to the bicipital tuberosity through CT. This would help to plan the optimal forearm position to access each quadrant and foresee the specific difficulties of each one. Material and method: We dissected 4 specimens of cryopreserved cadaver. We divided the radial head into 4 quadrants with regard to the bicipital tuberosity, objectifying the change of position in pronation and maximum supination with respect to the sigmoid cavity and neurovascular structures. Results: The head of the radio moves with pronosupination, so there are areas of convergence between the different quadrants. Quadrant1 is approached in supination via an anteromedial portal. Quadrant2 is approached in maximum pronation through a lateral portal. Quadrant3 can be approached through lateral portals, with the forearm in neutral position and in pronation. Quadrant4 is accessible with the forearm in a neutral position and in supination through a lateral portal. Conclusions: Depending on the location of the fracture in the head of the radius with respect to the bicipital tuberosity, we will need access through a specific arthroscopic portal, with the medial quadrants (anteromedial and posteromedial) being the most technically demanding

ABSTRACT

Objetivo: Valorar los resultados funcionales y radiológicos a corto plazo de la utilización de la placa gancho AO en el tratamiento quirúrgico de las luxaciones acromioclaviculares (AC) agudas de tipo iii. Material y método: Durante el período 2006–2008 se han realizado 70 intervenciones por lesiones (fracturas y luxaciones) de la clavícula, 26 de ellas luxaciones AC agudas o crónicas. Hemos analizado los resultados de las luxaciones agudas tratadas con una placa gancho AO. Material y método: La serie constaba de 11 luxaciones AC de tipo iii, con una edad media de 38 años. En 6 casos ocurrieron por accidente de tráfico y en 5 casos ocurrieron por etiología laboral. La media de la retirada de la placa fue a las 9 semanas (rango de 6–12semanas). Resultados: Los resultados funcionales de la serie según el test de Constant fueron de 94 puntos de media y la escala analógica visual fue de 2,1. El tiempo medio hasta la cirugía de las luxaciones agudas fue de 9 días. Todos los pacientes, menos uno, presentaban molestias subacromiales durante la fisioterapia y que desaparecieron al retirar la placa. Hemos observado un caso de pérdida de reducción tras la retirada de la placa y no hemos observado otras complicaciones significativas. Conclusiones: El tratamiento quirúrgico de las luxaciones AC agudas con la placa gancho AO, sin la reconstrucción del los ligamentos coracoclaviculares, ofrece un buen resultado. Hemos observado pocas complicaciones y ha permitido la reincorporación laboral de los pacientes sin secuelas (AU)


Purpose: Assess the short term functional and radiological results of using the AO hook plate in type III acute acromioclavicular joint dislocations. Materials and Methods: During the 2006–2008 period, we performed 70 interventions due to injuries (fractures and dislocations) of the clavicle, 26 of them being acute or chronic acromioclavicular joint dislocations. We analyzed the results of 11 acute cases treated with an AO hook plate. This group had an average age 38 years, 6 cases due to traffic accidents and 5 were related to accidents at work. The plate was with drawn at an average of 9 weeks (range 6–12 weeks). Results: The functional outcome of the series according to the Constant test of acute AC joint dislocations was a mean of 94 with the score on the VAS of 2.1. Average time to surgery for acute joint dislocations was 9 days. All the patients, except for one, had subacromial physical discomfort during physiotherapy with the abducted arm that disappeared after removing the plate. We observed a case of loss of reduction after removal of plate and did not observe any other significant complications. Conclusions: Surgical treatment of acute AC joint dislocations with AO hook plate, without reconstruction of the coracoclavicular ligaments, offers good results. We observed few complications, allowing the patients to return to work early without sequels (AU)
