Step 21
2.5 x 225 mm Pins are now placed from anterior lateral to
anterior medial across the tibia and the talus in order to
compress the ankle arthrodesis site. These pins should be
placed just anterior to the placement of the tibial portion of the
plate and just anterior to the talar portion of the plate. These
pins will penetrate the medial aspect of the distal tibia and
talus and puncture wounds are made as these pins penetrate
the skin. Care is taken to avoid injury to the posterior tibial
neurovascular bundle. The compression device is used to
determine the distance separating these two cross pins. (The
Achilles complex tends to give counter compression forces to
oppose the anterior compression devices.) Joint Compressors
are placed both medially and laterally.
Step 22
Joint Compressors
2.5 x 225 mm Pins
Squeeze the Compressor handles to compress the joint. Take
care to compress the joint evenly. Tighten the thumb screws
on the back of the Compressors to lock the ratchets in place.
Verify reduction with fluoroscopy.
More compression may be placed either medially or laterally
depending upon the joint preparation, and alignment desired.
Bone graft may be inserted to assist in the alignment process
prior to adding compression. Tighten the knobs on the
Compressor to hold the pins in place.
At this point a Guide Pin may be placed from the anterior
cortex of the distal tibia in a distal posterior direction into
the talus. A 6.5 mm cannulated screw such as the NexFix
Compression Screw with patented threaded washers can be
placed to strengthen compression of the construct. Care must
be taken to avoid the cross-screws in the talus. Attention must
be directed to the proposed screw route in the tibia as well.
This screw may also be placed following the placement of the
cross-screws fixating the plate.
