Abstract
A minimally invasive surgical screw fixation system and method are used in conjunction with fluoroscopy (i.e., C-arm), for percutaneous fixation of the facet joints of the spine through small incision ports. The approach is generally based on a right-triangle guidance system, positioned via the use of the C-arm and secured to the operative site. This particular configuration allows for percutaneous placement of screws across facet joints via known angles and pathways. The inventive instrumentation allows for the targeting of drill hole and, ultimately, the placement of the screws associated with the procedure.
