Due to the potential for infection, the limited supply of human cadavers, and the ethical concerns surrounding the use of human specimens, vertebrae from animal models, such as pigs [19], calves [1019], dogs [2027], sheep [2831] and deer [3234],have been widely used in spine research to replace human vertebrae.
