Resumen

El traumatismo craneoencefálico (LCT) es una situación común en los hospitales de traumatología y se ha convertido en responsable de las altas tasas de mortalidad en todo el mundo. Cuando la víctima de TBI se ve afectada por lesiones en el casquete con la necesidad de un injerto, eventualmente surgen problemas con respecto a la disponibilidad de materiales adecuados y asequibles. En este estudio, se desarrolló una estructura 3D de polieteretercetona que imita la morfología del hueso craneal para su uso en craneoplastia. Se obtuvieron muestras de diferentes formulaciones, en forma de barras redondas, mediante compresión uniaxial y se controló la porosidad mediante la técnica de lixiviación de sales. Luego, las muestras se caracterizaron en términos de morfología y distribución de los poros, rugosidad superficial, resistencia a la compresión y citotoxicidad. Los resultados mostraron altos niveles de similitud de las muestras con el hueso humano natural, lo que indica la efectividad del método propuesto para imitar la morfología del sistema compacto/poroso/compacto del casquete (diploe).
