Distal Femoral Cut Validation
1. Remove the pod attached to the femoral reference
and clip it to the validation tool.
2. Position the flat surface of the validation tool onto
the distal femoral cut.
3. Secure the validation tool on the distal femoral
cut using the captive spikes. Additionally two
3.5 X 38 mm hex head screw can be used for more
stability.
Warning: Care must be taken when impacting
the spikes of the validation tool to avoid
potential interference between the spikes and
the pins used to secure the femoral distal cut
guide and the femoral saw slot. If interference
is felt, the validation tool should be shifted
mediolaterally by 10 mm.
