Attach one 3.5 mm Hex Driver Shaft to the Blue-Handle Ratchet Driver and a second
3.5 mm Hex Driver to a power drill. Remove the 5 mm Drill and Drill Guide from the
Guide Sleeve. Insert the Headless PA Screw through the Guide Sleeve using the 3.5
mm Hex Driver loaded on the power drill until the screw has passed through the Nail
Implant. Then switch to the Blue-Handle Ratchet Driver to continue to advance the
screw until it is flush with the posterior calcaneus (E). Remove the Guide Sleeve
from the PA Attachment. Remove the PA Attachment from the Targeting Frame.
TECH TIP
• The Headless PA Screw does not provide tactile feedback to indicate when it is
fully inserted. Use the laser line on the 3.5 mm Hex Driver to determine if the PA
Screw is fully inserted. When the laser line approaches the back of the Guide
Sleeve, use lateral flouroscopy while advancing the final turns, ensuring the
screw tip does not breach the C-C joint.
