Abstract
Methods and apparatus for providing percutaneous access to vertebrae in alignment with a visualized, trans-sacral axial instrumentation/fusion (TASIF) line in a minimally invasive, low trauma, manner are disclosed. A number of related TASIF methods and surgical tool sets are provided by the present invention that are employed to form a percutaneous pathway from an anterior or posterior skin incision to a respective anterior or posterior target point of a sacral surface. The percutaneous pathway is generally axially aligned with an anterior or posterior axial instrumentation/fusion line extending from the respective anterior or posterior target point through at least one sacral vertebral body and one or more lumbar vertebral bodies in the cephalad direction. The provision of the percutaneous pathway described herein allows for the formation of the anterior or posterior TASIF bore(s) and/or the introduction of spinal implants and instruments.
