FEMORAL PREPARATION - A/P AND CHAMFER CUTS
Figure 16
Attach the HP Universal Handle to the Femoral Fixed
Reference Guide (P/N 2004-20-920) and position the
guide’s spikes through the “0” mm holes marked with a
square located at the bottom of the SIGMA Femoral Fixed
Reference Femoral 4-in-1 Cutting Block (Figure 15). Insert
the construct spikes into the previously drilled holes
located on the distal femoral bone cut. Check to verify
that the spikes of the fixed reference guide are in the
middle holes of the bottom hole cluster. It is possible to
position the spike through the top hole and opposite
bottom hole (vice-versa). This will result in an incorrect
rotation placement of the cutting block.
Evaluate the anterior cut with the angel wing (Figure 16). If
desired, the block may be shifted 2 mm anteriorly or
posteriorly by selecting the appropriate offset holes
adjacent to the “0” mm hole marked with the square. (See
notes section on page 11 for additional detail).
Secure the block’s location by inserting threaded headed
pins into the convergent pin holes on the medial and
lateral aspect of the femoral 4-in-1 cutting block. Remove
the handle/fixed reference guide assembly and perform
the femoral resections (Figure 17). After performing all
cuts, remove the pins and cutting block, making sure
bone cuts are clean and void of any under-cut bone
fragments.
