Step Eleven: Finish the Tibia
(cont.)
Technique Tip –
When encountering unusually hard,
sclerotic bone on the proximal tibia, it is recommended
to prepare the tibia prior to broaching. Attach the MIS
threaded handle to the MIS drill bushing and position
it on the broach plate (Figure 11b). Hold the MIS drill
bushing in place while drilling to ensure it remains in
full contact with the broach plate. Using the cemented
drill, drill half the distance to the engraved line on the
cemented drill (Figure 11c). This depth will prepare for
the length of the keel.
Note:
Make sure detents are engaged and bushing
remains in full contact with the sizing plate during
drilling.
Assemble the proper size MIS cemented broach to
the MIS tibial broach impactor (Figure 11d).
Seat the MIS tibial broach impactor assembly in the
corresponding broach plate holes (Figure 11e).
During broaching, make sure that the broach handle
remains flush against the broach plate and in full
contact with the broach plate and that the broach
handle does not toggle during impaction. Impact
the MIS tibial broach impactor assembly with care to
prevent fracture of the tibia (Figure 11f).
