Abstract (English): The number of patients with spine conditions has grown exponentially in recent years leading to an increase in the number of cases requiring surgical treatment. Currently vertebral fusion surgery with a transpedicular approach represents the most commonly used technique to treat any type of vertebral disorder. The morphometric characteristics of vertebrae, particularly the pedicle, determine the size of pedicular implants, including width and length, as well as the shape and direction of the screw and its ideal angulation at the time of introduction. Knowing these characteristics is important to prevent injuring important adjacent structures and to decrease the postoperative complication rate. In recent decades numerous studies on the morphometric characteristics of the vertebral pedicle have been conducted in different populations to determine its real dimensions by means of direct measurement and imaging methods. These studies have concluded that there are significant differences in these measurements among the different ethnic groups, races, genders, ages and the vertebral regions studied. This paper analyzes the different morphometric studies of the pedicle and all the other vertebral elements studied in Mexico and the rest of the world and explain the importance of their knowledge and surgical application for the correct development of vertebral fusion surgery with a transpedicular approach.

Abstract (Spanish): El número de pacientes que padecen patología de la columna vertebral se ha incrementado exponencialmente en los últimos años y con ello, se incrementará el número de casos que requerirán tratamiento quirúrgico. En la actualidad la cirugía de fusión vertebral por vía transpedicular representa la técnica de fijación más comúnmente utilizada para el tratamiento de desordenes vertebrales de cualquier índole. Las características morfométricas de las vértebras, en especial del pedículo, determinan el tamaño de los implantes pediculares tanto en anchura como en longitud, así como la forma, dirección y angulación ideal del tornillo al momento de su introducción. Es importante el conocimiento de estas características para evitar lesiones de estructuras importantes adyacentes, así como para disminuir la incidencia de complicaciones postoperatorias. En las últimas décadas se han efectuado numerosos estudios en distintas poblaciones sobre las características morfométricas del pedículo vertebral para determinar sus dimensiones reales mediante medición directa y métodos de imagen. Estos estudios han llegado a la conclusión de que existen diferencias significativas en estas mediciones entre las diferentes etnias, razas, géneros, edades y regiones vertebrales estudiadas. En el presente artículo se analizan los diferentes estudios morfométricos del pedículo y demás elementos vertebrales estudiados en México y el resto del mundo, justificando la importancia de su conocimiento y aplicación quirúrgica para el correcto desarrollo de la cirugía de fusión vertebral por vía transpedicular.
