Reusable and Disposable Instrument Tray:
Surgical Technique:
WIRE GUIDE WITHIN DRILL GUIDE
Wire Guides are inserted into the Drill Guides to place appropriate size K-wires, then removed prior to drilling. The Wire Guide Sleeve has a tapered body that will press-fit into the Drill Guide with light manual pressure.
CANNULATED DRILL WITHIN DRILL GUIDE
Remove the Wire Guide Sleeve, leaving the Drill Guide and K-wire in place. Drive the appropriate Cannulated Drill over the K-wire through the Drill Guide to the desired depth.
DEPTH GAUGE
Screw depth is determined by measuring over the K-wire with the Depth Gauge tool (2 sizes included in the instrument tray).
SCREW INSERTION
Attach the corresponding-sized Torx driver shaft to the ratcheting handle to insert the cannulated CoLag Screws. Prep and add additional CoLag Screw as needed.
