Cone Preparation

Femoral Central Cone Insertion
Remove the instruments from the femoral canal
and attach the QC handle to the appropriate
femoral cone impactor head (Figure 9). Insert the
femoral cone provisional that is the same size as
the last broach used and position into the femur
(Figure 10). The “0” line should align to the distal
surface of the femur. If distal augments are required,
the +5 and +10 markings on the femoral cone impactor
head represent the appropriate depth for insertion.
Note:
The cone impactors are used for both left
and right components, and must be rotated in
the correct orientation to accurately represent the
6 degree angle of the femoral stem housing.
Note: If the cone provisional is difficult to remove,
use the non-threaded end of the slap hammer to
hook under the cone (Figure 11).
Insert the femoral provisional construct into the femur
by hand. Assemble the QC handle and the femoral
impactor pad and impact the femoral provisional
construct into the femur (Figures 12 and 13).
Note: The line across the anterior flange of the
femoral provisional shows the minimum depth the
broach must be prepared into the bone and can be
used as a reference (Figure 14).
Note: If the femoral provisional construct does
not fit through the cone provisional, preassembly
of the cone provisional on the femoral provisional
is required. This assembly step applies to the final
construct assembly as well.
