Option: Implant Removal Irrigate and apply suction for removal of debris potentially generated during implant removal. 1 1. Remove Locking Screw(s) Instruments 03.168.014 or 03.168.016 03.010.516 Screwdriver Shaft Stardrive, T25, length 241 mm Screwdriver Shaft hexagonal, 3.5 mm, length 241 mm Handle, large, with Quick Coupling Remove the locking screw(s) by hand using the screwdriver shaft together with the appropriate handle and without torque limiter. (1) If the screw cannot be removed with the screwdriver, consult the separate publication “Screw Extraction Set” (DSEM/TRM/0614/0104). Note: If the implant is fully telescoped, resulting in the bolt being more lateral than the plate (2), pull on the plate (e.g. with surgical pliers) to extend it from the bolt (to about 5 mm) before conducting the steps on the following pages.

(1) 2 Options: • If it is difﬁcult to ﬁnd the recess of the antirotationscrew, then use the Insert (03.168.009) as a guide within the plate. (2) • If the antirotation-screw gets detached from the screwdriver, then use the multifunction rod and turn it clockwise to catch the antirotation-screw. Pull on the multifunction rod and turn anti-clockwise to fully remove the antirotation-screw. (3) If the antirotation-screw cannot be removed with the screwdriver or the multifunction rod, consult the separate publication “Screw Extraction Set” (DSEM/TRM/0614/0104). 3 1 2 39 Option: Implant Removal 3. Remove Plate and Bolt 1 Instruments 03.168.010 Multifunction Rod for Insertion Instruments 03.168.015 Cylinder, for Insertion Instruments Slide the cylinder over the multifunction rod. (1) Attach the multifunction rod by turning it clockwise. Use the direction of the previously removed antirotationscrew. (2) Tap outward with the cylinder to remove the plate and bolt simultaneously. (3) 2 Note: Avoid excessive forces during removal. 3 41
