Percutaneous Pars Fracture Repair

Speaker  The ultra minimally invasive, endoscopic assisted percutaneous approach for pars fractures using Arthrex spine compression screws is indicated for adolescent and adult population. During this procedure, a spine specific endoscope may be used for visualization and direct access of the fracture site for preparation and biologic delivery. The Synergy imaging system, in conjunction with the ergonomic instruments, provides innovative new technology to treat this pathology. Localize using AP and lateral fluoroscopy based on pre-op imaging and CT. Mark a line along the inferior edge of the lamina of the level being treated. Mark midline under AP. Determine the screw trajectory and mark from the top of the pedicle to midline. Repeat on both sides for bilateral treatment using lateral fluoroscopy. Determine the screw trajectory and mark the skin. This will provide a reference for the AP entry point. Using AP and lateral fluoroscopy, Make a skin incision and insert the introducer needle. Docking on the inferior edge of the lamina. Remove the stylet and insert the guidewire through the cannula of the introducer needle. Use AP and lateral fluoroscopy to make fine adjustments to the entry point. Use a pin driver to advance the guidewire across the fracture, confirming the trajectory with AP and lateral fluoroscopy periodically during insertion. Widen the skin incision to accommodate the dilator and drill guide diameter. Speaker  Remove the introducer needle, then insert the dilator and drill guide over the guidewire, granting the bevel of the tip of the drill guide to best match the patient's anatomy. Remove the dilator and insert the drill bit over the guidewire. Position the drill bit coaxial with the guidewire and drill to the desired implant. Depth, confirming trajectory and depth with fluoroscopy periodically making sure to not advance the guidewire while drilling. Observe the drill depth via the laser line and the corresponding measurement on the drill guide to determine implant length. Reverse the drill bit under power 10 to 15mm. Stopping before the drill bit tip passes the fracture location. Remove the guide wire and insert a new guide wire. Continue to remove the drill bit using a ratcheting handle while maintaining the guide wire depth and location. Load the compression screw firmly under the screwdriver. Place the cannulated implant and screwdriver over the guide wire and advance to the desired depth. Periodically taking AP and lateral fluoroscopy to prevent advancement of the guide wire. The compression screw will be fully seated when the laser line on the screwdriver is flush with the back of the drill. Guide to confirm proper position. Remove the instruments. Close the incision and place a JumpStart bandage over the incision site.
