The talar window trial is used to check that all talar cuts are complete
and accurate. (FIGURES 34a+b) If the window trial does not fit, the
bone rasp is used to remove excess unresected bone. (FIGURE 37)
Preparation of the Keel
Place two 2.4 mm pins in the anterior holes on talar window trial
for additional stability during keel preparation. (FIGURE 35) The
straight keel mill (FIGURE 36) is placed in the center slot of the
window trial. The mill can be utilized with a drill or wire driver. The
straight mill is pushed into the talar surface until it is flush with the
stop on the mill and moved anteriorly on the slot. (FIGURES 37a+b)
