Lag Screw Placement (cont.)
Remove the 3.2 mm lag screw pin sleeve from the
lag screw cannula. Slide the cannulated depth
gauge over the 3.2 mm guide pin down to the bone
(Figure 20).
Confirm that the depth gauge is touching the lateral
cortex of the femur using fluoroscopy to accurately
determine the length of the lag screw to be used. The
end of the guide pin in the depth gauge indicates
the length of the lag screw to be used.
Slide the lag screw stop assembly onto the lag screw
reamer (Figure 21). Place the window in the stop
over the number measured with the cannulated
depth gauge (Figure 22). If the measurement was
between markings on the cannulated depth gauge,
set the stop to the smaller number.
