Powerpoint as a Useful Tool in Corrective Osteotomies Calculation—Case Report and Presentation of the Method

Abstract

Malunion or congenital disorders of the forearm might lead to biomechanical alterations and change the pronosupination motion. Occasionally, an osteotomy should be performed to correct this malalignment. Several techniques have been reported, especially 3D modeling, which is not yet widely used due to its cost. The traditional method is still mostly performed, but sometimes it may be difficult to do the preplanning. In this paper, we explain an easy method, called “giro point” technique, to perform the calculation of osteotomies using commercially available software. We present six clinical cases with good functional results, in which the calculation was performed using this method. The method is easy to follow, with adequate surgical-radiological correlation.

Resumen

Las deformidades congénitas o maluniones del antebrazo pueden generar alteraciones biomecánicas, cambiando la pronosupinación. Ocasionalmente, se recurre a una osteotomía para corregir la desalineación. La literatura reporta múltiples técnicas, con la modelación 3D en boga, pero dado su costo actual, no es usada masivamente. El método tradicional se sigue usando, sin embargo puede resultar dificultosa la planeación prequirúrgica. En este artículo se presenta una forma sencilla de realizar el cálculo de la osteotomía denominado método de “punto-giro,” con un software comercial. Se presentan 6 casos, con buenos resultados funcionales, cuyos cálculos fueron hechos con este método. El método es fácil de seguir, con adecuada correlación quirúrgico-radiológica.
