Option: Intra-Operative Compression Inter-fragmentary compression may be applied intraoperatively. The locking screw as well as the antirotationscrew need to be inserted prior to applying compression. 1 1. Attach Multifunction Rod for Compression Instrument 03.168.010 Multifunction Rod for Insertion Instruments Insert the multifunction rod through the guide of the antirotation-screw. (1) Hand-tighten the rod by turning it clockwise until the rod is fully inserted. (2) 2 35 Option: Intra-Operative Compression 2. Apply Compression 1 Note: • If applicable (e.g. if using a traction table), consider to loosen traction before applying compression. • Monitor the implant position during compression using the image intensifier. Apply inter-fragmentary compression by turning the screw of the insert counter-clockwise. (1) Precaution: Applying compression by hand is sufficient. Using additional tools for compression might cause excessive forces. Before Compression 36 After Compression 3. Remove Multifunction Rod 1 Remove the multifunction rod by turning it counterclockwise. (1) Note: If loosening by hand is not possible, then use another instrument (e.g. a screwdriver shaft) through the hole in the multifunction rod to untighten it. Use image intensiﬁcation to conﬁrm that the antirotation-screw remains locked in the implant. 37
