Abstract
An apparatus and method of performing a minimally invasive posterior spine fusion. More specifically an apparatus with a handle and a forked head on the distal end of the handle is used to grasp implant material and introduce the material to an implant site. The shaft of the apparatus is shaped so as to allow the affixation of a drill guide and drill while simultaneously holding the implant material in the implant site. After removal of the boring tools and assembly of the fusing element, the apparatus can be selectively removed from the implant site. A method of achieving facet joint fusion with near simultaneous fixation is also disclosed.

An apparatus for providing fixation of adjacent vertebral bodies comprising:
- a handle;
- an elongated shaft;
- a head coupled to the elongated shaft;
- wherein the head further comprises a forked end having two or more tines for grasping a bioactive implantable material which is adapted to be inserted into the joint space between two or more intervertebral bodies, wherein each of said two or more tines are free-standing with a first proximal end and a second distal end, wherein said second distal end is not connected to a distal end of another of said two or more tines;
- and
- wherein the elongated shaft further comprises a generally cylindrical body having a continuous, hollow portion about a longitudinal axis of the generally cylindrical body, which is in communication with at least one aperture located at the distal end of the elongated shaft;
- and
- wherein said head is composed of bioactive implant material.
