Lumbar Pedicle Screw Fixation is a minimally-invasive procedure uses special guides and fluoroscopic imaging to allow a surgeon to precisely implant stabilizing screws and rods in the spine while minimizing damage to muscles, tendons and other soft tissue in the back.
After anesthesia is administered and the patient is positioned, the spine is scanned with an imaging system. This allows the surgeon to plot the paths of the pedicle screws down to the vertebrae. The surgeon then creates the entry points – a few tiny incisions on the back.
A probe is inserted through the first incision and guided with fluoroscopic imaging to the spine. When the probe is correctly positioned at the point where the screw will be inserted, a nguide wire is placed gently down to the pedicle and the probe is removed. The surgeon repeats this for each screw placement point.
The pedicle screws are threaded onto the guide wires, gently placed down to the vertebrae, and carefully screwed into the bone.
