La escasez de colecciones osteológicas que incluyen fetos identificados implica la busca de recursos no convencionales para investigar la variación anatómica fetal. En un trabajo anterior, desarrollamos ecuaciones para estimar la edad gestacional (AG) en el momento de la muerte mediante la medición de huesos largos fetales en radiografías. Este estudio tiene como objetivo demostrar la aplicabilidad de estas ecuaciones en huesos secos y evaluar su precisión y bies.

Se empleó una muestra de prueba de 17 fetos con edad gestacional conocida en el momento de la muerte de la colección osteológica del Departamento de Medicina Legal, Toxicología y Antropología Física de la Facultad de Medicina de la Universidad de Granada (España). Los huesos examinados fueron el fémur, la tibia, el húmero y el radio.

Los modelos propuestos revelan una precisión elevada y un bies bajo en la evaluación de la AG en el momento de la muerte en una muestra de huesos fetales. Las nuevas ecuaciones, especialmente las obtenidas con la calibración clásica, son una herramienta valiosa para estimar la edad gestacional fetal en el momento de la muerte, tanto en contextos forenses como arqueológicos.
