Please if someone knows how to translate the following words/phrases I would be very grateful.

canal raquimedular (not in Diccionario Mosby de Medicina)

metastasicas (not in Diccionario Mosby de Medicina)

los cuerpos y elementos (seems obvious, but not sure of other meanings)

platillos terminales

osteofiticos (seems obvious but not in Mosby)

Thanks ahead of time for anyone's help
