Lateral Tibio-Talar Plate (AFPTTL and AFPTTH)
For Lateral Joint preparation, see pages 10-13.
Step 16
Use the X-ray template to select the Lateral TT Plate that best
fits the Talar anatomy.
Two TT plates are available:
- 15˚ distally angled portion against the talus (AFPTTL)
- 30˚ distally angled portion against the talus (AFPTTH)

Lateral Tibio-Talar Plate
Step 17
Use 2.0 x 150 mm Pins to temporarily fix the joint. Position the
plate on the bone. Ensure that the distal end of the plate sits
fully on the talus and does not extend down into the subtalar
space or onto the calcaneus. Evaluate plate fit to the tibia. Bend
the plate with the Plate Benders if necessary. Pin the plate to
the talus (it is not recommended to use two pins in the talar
part of the plate to prevent interference with the bone screw
insertions later in the procedure). Attach the Talus Hole Guide
to the Plate. Attach Driver Handle to the Guide Post if desired.
Remove any protuberances that interfere with plate fit.
Lateral Talus Hole Guide 2.5 x 150 mm Pins
Insert Drill Guide into one of the proximal holes in the Talus
Hole Guide. Make sure that the laser etched line on the Drill
Guide sits flush with the Hole Guide. Drill the screw hole in
the talus, avoiding penetration into the subtalar joint.
Pivot the post to the side to avoid interference with the
other instrumentation.
Use the Depth Gauge to measure the hole. Select the
appropriate screw length. Use the Driver Bit and Ratcheting
AO Driver Handle to insert the screw.
