Lumbar Pedicle Screw Fixation

(CD HORIZON® SEXTANT™)

This minimally-invasive procedure uses special guides and fluoroscopic imaging to precisely implant stabilizing screws and rods in the spine while minimizing damage to muscles, tendons and other soft tissue in the back.

After imaging the spine to plot the position of the screws, the surgeon creates a few tiny incision 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 guide wire is placed gently down to the pedicle (the bone supporting the spinal arch) and the probe is removed. This procedure is repeated for each screw placement point.

Then the pedicle screws are threaded onto the guide wires, gently placed down to the vertebrae, and carefully screwed into the bone. To stabilize the spine, metal rods are needed to connect the pedicle screws. A device called the SEXTANT device is used to insert the connecting rods without a large incision. One at a time, the rods are attached to the device and inserted through small incisions. Each rod is gently placed into the screw heads, locking the screws together.
