Step 16
Remove all cross-joint pins. Insert one end of the Compressor
in the proximal hole of the Tibia Hole Guide as shown. Push it
down fully to the bottom of the hole. Position the other distal
end of the Compressor on the tibia, above the proximal end
of the plate, leaving sufficient room so not to interfere with
the plate when compression is applied. Typically a 10 mm gap
or more is adequate between the proximal end of the plate
and the Compressor. Position the proximal Compressor collet
longitudinally in line with the plate. Insert a 2.5 x 100 mm Pin
through the collet on this compressor end and drive it into the
tibia bicortically. Turn the knob to tighten the collet against
the pin. Keep the Compressor fully seated in the hole of the
Tibial Hole Guide during this step, and avoid rotating the
Compressor handles towards the proximal pin. If necessary,
loosen the knob and realign the Compressor and tighten the
knob again. Squeeze the Compressor handles. Tighten the
thumb screw on the back of the Compressor to lock the
ratchet in place.

Surgical Note:
Keeping the Compressor straight will typically result in a small
gap between the tibial cortex and the proximal Compressor
end on the pin. This is acceptable.
Take care to compress the joint evenly. Avoid rotating the tibia
during compression and creating a gap in the posterior joint
space. Verify reduction under AP and lateral fluoroscopy. If
necessary, release the compression, remove the Compressor,
plantarflex the ankle and use the Plate Benders to bend the
plate at the two bending zones for a better fit or even compression.
Step 17
Insert the Drill Guide into each of the proximal screw holes.
Seat the guide squarely on the shoulder in the hole. Drill the
proximal plate screw hole. Use the Depth Gauge to measure
the hole’s depth. Select the appropriate screw length and
place the screw. Repeat the process for the other screw hole.

Alternatively, two Compressors may be used to compress the
joint. Position one on either side of the plate, across the joint, at
approximately 70° from each other – like the Distractors were
positioned in Step 2. Use 2.5 x 100 mm Pins to secure one end
of each Compressor into the tibia and other end in the talus.
Tighten the collets against the pins. Squeeze both handles to
compress the joint.
