Abstract:
1. A guide pin assembly for guiding instrumentation along a soft tissue tract to a point on the spine, comprising: a guide pin introducer comprising an introducer handle and a rigid elongate introducer tube extending from the introducer handle, the introducer tube having a introducer tube length extending between an introducer tube proximal end and an introducer tube distal end, the introducer tube length configured to extend from a skin incision near the paracoccygeal region through the pre-sacral space to an anterior target point on a sacral vertebral body, the guide pin introducer defining a lumen having a lumen diameter; a guide pin slideably positionable within the lumen of the guide pin introducer, comprising: a blunt tipped stylet having no lumen extending longitudinally therethrough, slideably positionable within the lumen of the guide pin introducer and comprising a blunt tipped stylet outer diameter less than the guide pin introducer lumen diameter and a blunt tipped stylet proximal stop positioned on the blunt tipped stylet such that a distal end of the blunt tipped stylet extends distally of the introducer tube distal end; wherein the blunt tipped stylet outer diameter is substantially the same as the rod outer diameter.
