Abstract

Disclosed herein are systems and methods for dilating tissue for placement of a pedicle screw without the use of guide wires. The tissue dilation system includes, generally, a stylet and trocar which are used for the initial placement of the tissue dilation system. A second dilator is passed over the first. A second dilator is passed over the first dilator, and further includes a serrated edge for engaging with a target surface. The second dilator may be secured to the target surface by the serrated edge alone, or may additional be secured using one or more temporary fixation pins, which operably couple to the second dilator.
