Tibial Cone Implantation
1. To insure proper Cone Implant placement and
orientation, insert the appropriate LEGION™ Reamer
(or Trial Stem and Trial Stem Connection Rod
Assembly) into the canal.
Caution: Without LEGION Reamer or Trial Stem/Trial
Stem Connection Rod in the canal, the final cone
implant may be malaligned.
2. Assemble the Neutral Sleeve and appropriate
Tibial Cone Impactor Head to the Cone Handle.
3. Using the previous orientation and size used with
the final Tibial Cone Broach and Tibial Cone Trial,
lightly impact the selected Cone Implant into the
Tibia to the desired depth and orientation.
Caution: If excessive force is used, fracture
may occur.
Tip: After the Cone implant is placed, fill any
existing voids between the Cone and the
endosteal of the tibia with grafting material
(Figure 55).
Cementing
1. If using a hybrid cementing technique, ensure
a sufficient amount of cement is applied to
Tibial Tray/Stem Implant construct to fill the
area between the Cone’s internal diameter
and the Tibial Tray/Stem Implant Assembly
prior to insertion of the Tibial Tray/Stem
Implant Assembly.
Tip: A final depth measurement of the cone
can be taken using the Cone Removal
Tool (Figure-56a) and transferred to the
implant construct (Figure-57a).
