Instruments
389.193 Parallel Distractor
8203 Preoperative Planner
Determine the height of the corpectomy site using the
parallel distractor. The scale on the handle of the parallel
distractor indicates the height of the implant needed to fill
the void. Use the preoperative planner and the following tips
for ease of implant selection:
– The height of the implant in its starting position should be
less than the undistracted corpectomy height.
– Subtract 4 mm from the value read on the distractor scale
to account for the height of the three tallest spikes.
– The maximum expanded height of the implant should
exceed the measured corpectomy height.
