RESUMO
Objetivo. Estudio retrospectivo de 98 fracturas diafisarias de antebrazo en adultos tratadas mediante osteosíntesis percutánea intramedular con agujas de Kirchner. Materiales y método. Se revisan 64 pacientes que presentaban 98 fracturas de antebrazo con un seguimiento clínico-radiológico, evaluando la presencia de seudoartrosis o retardo de la consolidación y valorando los resultados funcionales mediante la Escala de Anderson y el Disability of the Arm, Shoulder and Hand. Resultados. La consolidación clínica y radiológica se consiguió con una media de 12 semanas, obteniendo un 77% de excelentes y buenos resultados con los criterios de Anderson. Se registraron 4 casos de seudoartrosis y 6 casos de retardo de consolidación. Conclusión. La osteosíntesis percutánea presenta una serie de ventajas con respecto a otras técnicas como son una baja incidencia de complicaciones, ausencia de infecciones, refracturas y lesiones yatrogénicas vasculonerviosas. Se consigue una menor estancia hospitalaria y un acortamiento del tiempo quirúrgico, con unos resultados similares al tratamiento con placas y clavos endomedulares en cuanto a consolidación y resultados funcionales, como comprobamos al consultar la bibliografía publicada (AU)
Objective. This is a retrospective study of 98 diaphyseal forearm fractures in adults, treated by a percutaneous technique with intramedullar Kirchner wires. Materials and method. We reviewed 64 patients with 98 forearm fractures with a radiographic follow-up, assessing the presence of pseudarthrosis or delayed bone union and evaluating functional outcomes with the Anderson and the Disability of the Arm, Shoulder and Hand scale. Results. Clinical and radiological bone union was achieved in an average of 12 weeks. We obtained 77% of excellent and good results following Anderson's scale. There were 4 cases of pseudarthrosis and 6 cases of delayed bone union. Conclusion. This surgical technique provides several advantages, such as a low incidence of complications and a total absence of infections, refractures and iatrogenic neurovascular injuries. It allows a lower hospital stay and a shortening of the surgery time compared with other techniques such as plates and intramedullary nails, that have similar results, in terms of bone union and functional outcomes, as we have verified from the published literature (AU)

El presente artículo de revisión pretende ser una puesta al día en un tema, ciertamente controvertido en los últimos años, debido a los problemas derivados del par de fricción metal-metal, dadas las altas expectativas que tuvo en sus inicios. Pretendemos analizar los conceptos fundamentales, así como su tribología y revisar sus ventajas, desventajas y pautas de seguimientos en pacientes portadores de este par de fricción
This article of review updates the friction couples metal on metal, which certainly have been controversial in the last few years, due to the problems with it, because of the high expectations given to it from the beginning. In this article, we try and analyze the fundamental concepts of the friction couples as well as its tribology and check its advantages, disadvantages and guidelines amongst the patients who have the implant
