TECHNIQUE TIP 6.B
Do not impact the anterior flange of the PS Femoral Provisional. Do not
impact the medial or lateral aspects or the release lever of the
Femoral Inserter/Extractor.
TECHNIQUE TIP 6.C
Do not impact the PS Box Cut Guide into the provisional.
• Remove any posterior osteophytes or overhanging bone
on the femur to facilitate maximum knee flexion. Attach
the Femoral Inserter/Extractor to the correct PS Femoral
Provisional by inserting the tab on the Femoral Inserter/
Extractor arm into the lateral notch in the PS Femoral
Provisional and close the handle on the Femoral Inserter/
Extractor to secure the PS Femoral Provisional
(Fig. 32) .
Place the correct PS Femoral Provisional onto the femur in
the desired medial/lateral position. Impact the end of the
Femoral Inserter/Extractor handle and apply an upward
force to fully seat the PS Femoral Provisional onto the femur
in the proper orientation.
(Fig. 33) . To remove the Femoral
Inserter/Extractor from the PS Femoral Provisional, pinch
the release lever on the proximal portion of the Femoral
Inserter/Extractor
(Fig. 33) . Alternatively, if the PS Femoral
Provisional is placed on the femur by hand, the PS Femoral
Impaction Pad/inserter assembly can be used to impact
the provisional into the femur. If this insertion/impaction
method is used, the inserter handle must be in the closed
and locked position. For additional fixation of the fully
seated PS Femoral Provisional, insert the 25mm x 3.2mm
screw (2.5mm female hex) with the 2.5mm Male Hex Driver
through the hole in the lateral anterior flange of the PS
Femoral Provisional
(Fig. 34a) .
Note: Do NOT use a 48mm screw in the anterior lateral fixation
hole of the PS Femoral provisional. 48mm screws are not
recommended due to potential bone perforation.
• By hand, insert and hold the correct-sized PS Box Cut Guide
into the anterior holes of the PS Femoral Provisional (Fig. 34b) .
For additional fixation of the fully seated PS Box Cut Guide,
insert the 25mm x 3.2mm screw (2.5mm female hex) with the
2.5mm Male Hex Driver through one of the holes in the PS Box
Cut Guide. Separate PS Box Cut Guides exist for the PS Femoral
Provisional for sizes 3-5,6-9, and 10-12.
