Tibial Baseplate Provisional
Assembly and Insertion
Note: If planning to prepare for an augment while
trialing, proceed with building the tibial provisional
construct without the keel provisional.
Disassemble the stem provisional from the
stem extension post and select the tibial
baseplate provisional that matches the same
size tibial sizing plate used. Select the tibial keel
provisional that matches the tibial size. Place
the keel provisional onto the tibial baseplate
provisional aligning the fins with the tabs on
the underside of the tibial baseplate provisional
(Figure 34). Attach the stem provisional to the tibial
baseplate provisional. Hold the baseplate screw in
place with your index finger and rotate the stem
provisional in a clockwise direction (Figure 35). Use
the 5 mm hex driver for final tightening (Figure 36).
Note:
The fixed keel provisional (not kitted) does
not have a modular keel attachment. No keel
assembly is required.

If an offset stem provisional is used, ensure the
offset number determined previously is aligned
with the anterior mark on the tibial keel provisional
or the stem housing on the tibia provisional
(Figure 37). Rotate to the planned offset, then
lockdown using the 5 mm hex driver.
