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. Las fracturas que afectan al capitellum pueden ser tratadas quirúrgicamente mediante escisión del fragmento, o mediante reducción y fijación interna con tornillos con o sin cabeza. El abordaje lateral de Kocher es el más usado para la reducción abierta. Creemos que el abordaje anterior limitado del codo podría ser una opción válida para tratar este tipo de fracturas, ya que no implica la desinserción de ningún grupo muscular ni de ningún ligamento y facilita la colocación anteroposterior de los tornillos, que ha demostrado ser biomecánicamente superior. Material y método. Describimos la técnica quirúrgica y evaluamos los resultados en 2casos clínicos con una fractura de tipo 1 de Bryan y Morrey (tipo 1A de Dubberley) mediante evolución clínica y radiológica. Dos cuestionarios diferentes sobre calidad de vida fueron realizados por teléfono: el EuroQol Five Dimensions Questionnaire (EQ-5D) y la porción contestada por el paciente del Liverpool Elbow Score (PAQ-LES). Resultados. Los 2pacientes presentaron una evolución clínica favorable a los 36 y 24 meses, respectivamente con un arco de movimiento de extensión/flexión de −5°/145° y −10°/145°, así como una pronosupinación de 85°/80° y de 90°/90°. Los 2pacientes presentaron consolidación radiológica sin signos de osteonecrosis, con el EQ-5D de 0,857 y 0,910 (rango: 0,36-1) y el PAQ-LES de 35 y 35 (rango: 17-36), respectivamente. Conclusiones. Creemos que el abordaje anterior limitado del codo es una opción técnica que tener en cuenta en caso de decidirse un tratamiento quirúrgico abierto de una fractura de capitellum, si bien necesitamos de estudios posteriores que demuestren su superioridad y seguridad clínica con respecto al abordaje clásico lateral de Kocher (AU)


Objective. Fractures involving the capitellum can be treated surgically by excision of the fragment, or by reduction and internal fixation with screws, with or without heads. The lateral Kocher approach is the most common approach for open reduction. We believe that the limited anterior approach of the elbow, could be a valid technique for treating these fractures, as it does not involve the detachment of any muscle group or ligament, facilitating the recovery process. Material and method. A description is presented of the surgical technique, as well as of 2cases with a Bryan-Morrey type 1 fracture (Dubberley type 1A). Two different final quality of life evaluation questionnaires were completed by telephone: the EuroQol Five Dimensions Questionnaire (EQ-5D), and the patient part of the Liverpool Elbow Score (PAQ-LES) questionnaire. Results. The 2patients showed favourable clinical progress at 36 and 24 months, respectively, with an extension/flexion movement arc of −5°/145° and −10°/145°, as well as a pronosupination of 85°/80° and 90°/90°. The 2patients showed radiological consolidation with no signs of osteonecrosis. The EQ-5D score was 0.857 and 0.910 (range: 0.36-1), and a PAQ-SLE of 35 and 35 (range: 17-36), respectively. Conclusions. We believe that the limited anterior approach of the elbow is a technical option to consider for the open surgical treatment of a capitellum fracture, although further studies are needed to demonstrate its superiority and clinical safety compared to the classical lateral Kocher approach (AU)
