Abstract

Flexible shavers and curved access ports that reduce access and trajectory problems associated with conventional lateral approaches to the lower spine. These devices and methods allow for preparing a disc space in the lower spine at an angle that is parallel to the disc space. Consequently, these devices and methods allow for preparing with less endplate damage.
