Step Three: Cut the Distal Femur
(cont.)
If more fixation is needed, use two 3.2 mm headed
screws (Figure 3d) or predrill and insert two hex-head
holding pins in the small oblique holes on the mini
distal femoral cutting guide, or silver spring pins may
be used in the large oblique holes.
Completely loosen the attachment screw (Figure 3e) in
the distal placement guide. Then use the slaphammer
extractor to remove the IM alignment guide and the
distal placement guide.
Cut the distal femur through the cutting slot in the
cutting guide using a 1.27 mm (0.050 in.) oscillating
saw blade (Figure 3f). Then remove the cutting guide.
Check the flatness of the distal femoral cut with a flat
surface. If necessary, modify the distal femoral surface
so that it is completely flat. This is extremely important
since this cut guides the placement of all subsequent
guides and to help assure proper fit of the implant.
