Pedicle awl (perforate cortex, pilot hole) 2. Pedicle probe (open Pedicle path, demarcations for depth) 3. Ball-tip probe (check 4 walls and floor, no violation of pedicle) 4. Tap (relieve stress on cortical bone, path for Pedicle screw Does a surgeon need to tap? No, screws are self-tapping Are the taps undersized? Yes, 0.2mm 4.0mm diameter not undersized Can a surgeon undersize the tap by a whole screw size? No, pitch changes on threads of screw, excessive cutting of bone Why is it important to decorticate around the screw head? Clear tissue, bone, maintain polyaxial motion How can a surgeon discern if a tulip is unlocked or locked? Saddle up position, silver saddle showing What is the identifiable difference between AMP and preassembled screws? Modular saddle-fuscia Preassembled-gold Where are straight rods located? Bottom of rod caddy Name all 6 reduction options and reduction capabilities 1. Locking cap guide: 3mm 2. Reduction fork: 5mm 3. Ratcheting, pistol grip: 10mm 4. Ratcheting, overhead: 10mm 5. Tower reducer: 20mm 6. Reduction clip: 30mm What is reduction? Pulling screw to rod How can a surgeon know when an instrument is fully reduced? Black etched line Can a locking cap driver fit down a reduction instrument? Yes What is the identifiable difference between the Counter-torque and locking cap guide? Locking cap guide fit locking cap through, larger diameter Why should the Locking Cap Guide not be used for final tightening? Too much play What are the various torque-limits? Blue: 5.5Nm Black: 8.0Nm Grey: 10Nm What is remobilization? Polyaxial motion When is remobilization necessary? Accessing drive feature, remove screw head
