An orthopedic fastener including a shaft may have a plurality of compound parabolic petals extending helically around the shaft. The petals may be configured for compressing trabecular bone through which the petals are inserted. The shaft may further include one or more force diffusion areas that may more efficiently redirect/distribute radial forces caused by an external force applied to the orthopedic fastener, to keystone portions of trabecular bone compressed respectively against the force diffusion areas.
