Sequential Broaching
1. With the LEGION™ Reamer (or Trial Stem and Trial
Stem Connection Rod) remaining in the canal,
place the Cone Handle with appropriate Variable
Offset Sleeve assembled with the 18mm Tibial
Broach at the desired length, ‘Short’ or ‘Long’,
over the shaft of the Reamer (Figure 64).
Note: A maximum of 25° of rotational freedom
is provided between the Tibial Cone and the
Tibial Tray fins/keel with no offset. Using offsets
reduces the amount of rotational freedom.
2. With attention to rotational alignment, lightly
impact the Cone Handle Assembly with a mallet
until the desired depth is reached.
Caution: If excessive force is used, fracture
\may occur. It is advised to broach in and
out to relieve stresses on the bone.
Note: The depth should be at or below the
cut tibial surface including below any additional
hemi augments planned.
Tip: 5mm depth marks are provided on the Cone
Handle for additional depth referencing against
planned augment thickness (Figure 65a).
3. While utilizing the same alignment orientation
as the previous broach, sequentially broach with
the next larger size until the desired size and
stability is reached.
