RESUMEN
En cirugía ortopédica existe cada vez mayor demanda de injertos óseos debido al incremento en el número y la complejidad de las cirugías. El actual estándar de oro es el injerto óseo autólogo, sin embargo, sus tasas de no unión, morbilidad en el sitio de toma del injerto y la limitada cantidad con la que se cuenta, han fomentado el surgimiento de diferentes alternativas al mismo, que funcionan como sustitutos óseos. Para obtener éxito en su utilización, se deben conocer las distintas propiedades de cada una de estas alternativas y del ambiente en el que van a ser colocadas. A medida que los sustitutos óseos y los factores de crecimiento se conviertan en realidades clínicas, un nuevo estándar de oro será definido. Las técnicas de ingeniería de tejidos y terapia génica tienen como objetivo crear un sustituto óseo óptimo, con una combinación de sustancias que tengan propiedades osteoconductivas, osteoinductivas y osteogénicas.
