Positioning the tibial sizer for offset stems
When using tibia blocks, appropriate manipulation tibia
blocks («5 mm», «10 mm» and «15 mm») are available. They
are fixed laterally on the manipulation tibial component
( tibial sizer ).
The tibial sizer is positioned with the transfer guide so it
does not project. It should in good contact on the cortical
bone all round.
Important
When using tibial blocks place the corresponding blocks on
the tibial sizer. Note the corresponding thickness («5 mm»,
«10 mm» or «15 mm») and side ( «Rlat/Lmed» or «Llat/
Rmed» ). The 15mm tibial blocks are anatomically bent M/L
and posterior. Therefore, the under contour is always
smaller a size than the upper contour.
If the decision is made that an offset stem is not required,
see page 36 for the following steps.
When the rotation has been adjusted, the tibial sizer is
fixed with the inclined bone pin holes.
Important
The vertical bone pins must be inserted before preparation
of the stem connection.
