Tibial Cone Trialing
1. Remove the last Tibial Cone Broach from the
Cone Handle, noting the broach size and
length, and assemble the corresponding size
Tibial Cone Impactor Head and Tibial Cone
Trial (Figure 52).
2. Insert the Cone Trial into the prepared tibia
utilizing the same alignment orientation as
the previous broach.
Note: The Tibial Cone Trials are the same
external size as their corresponding Tibial
Cone Broaches, therefore, little to no impaction
should be required for the Tibial Cone
Trial placement.
3. Complete the remaining steps in the LEGION™
RK or LEGION HK surgical technique after the
Counterbore section up to Implant Assembly
(i.e. trial placement, trial ROM, set rotation, fin
punch and hemi-augment resections if not
previously completed).
Cone Trial Removal
1. Insert the cone removal tool into the trial until
the hooks are just past the distal edge of the
trial. Attach the T-Handle to the removal tool
(Figure 53a) and rotate until the arms expand
to grip the Cone Trial.
2. Attach the Slap Hammer to the Cone Removal
Tool and remove the Cone Trial (Figure 53b).
