“By adding threads under the head, the CoLag Screw gives me the benefits of both a headed and headless screw. You can see and feel the stages of compression as the screw engages. Providing threaded fixation to the near cortex gives me the extra confidence of Compressive Stability.”

Colag CS Screws vs Headless Screws
Reusable and Disposable Instrument Tray
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.
Screw depth is determined by measuring over the K-wire with the Depth Gauge tool (2 sizes included in the instrument tray).
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.
