Appendix D: Tibial Central Cone
Implant Assembly
Cone Insertion
On the back table, use the provisional constructs as
a guide for building the final implants. Verify that the
stem implant will pass through the Trabecular Metal
Central Tibial Cone Implant.
If the stem implant does not pass through the
Trabecular Metal Central Tibial Cone Implant, you
will need to preassemble the Trabecular Metal Tibial
Cone Implant to the tibial baseplate implant prior
to implanting the construct. Proceed to the Tibial
Cone Assembly with an Offset or Large Diameter
Stem section, on page 58 for assembly instructions, if
necessary.
Assemble the appropriate tibial central cone impactor
head to the QC handle by pulling back on the lever and
attach (Figure 1).
Implant the Trabecular Metal Central Tibial Cone
Implant into the tibia using the QC handle and ensure
proper rotation and location of the keel cut outs
(Figures 2 and 3). Impact until fully seated in the tibial
canal (Figure 4).
If excessive force is required to seat the cone implant,
tibial fracture may occur. If necessary, consider re-
broaching the cavity.
If gaps exist between the periphery of the cone and
the endosteal surface, bone grafting material may be
utilized with autogenous bone, allogenic bone or bone
putty.
Proceed to the Tibial Implant Assembly section on
page 37.
