Tibial Sizing and Positioning (cont.)
Offset Stem Preparation
Note: Offset stems are available in the splined
configuration only.
The offset stem reamer adapter has two holes, one for
3 mm offset and one for 6 mm offset (Figure 20). Once
the tibial size has been estimated, insert the offset
stem reamer adapter to the tibial sizing plate and slide
over the reamer. Confirm that the “ANT” marking
on the offset stem reamer adapter is facing anterior
(Figure 21).
Rotate the tibial offset stem reamer adapter until the
preferred offset is achieved which provides the best
tibial plateau coverage while maintaining rotational
alignment (Figure 22). Resize the tibia, if necessary.
Note:
The numbers on the tibial offset stem reamer
adapter determine the selected offset direction of
the tibia with respect to the stem.
