2997-04-230 X25 Inserter/Tightener
2997-04-135/140 T-Handle/Tear-Drop Handle
Flex Clip Reducer Assembly - Comprised of:
2997-04-270 Flex Clip Reducer, Flex Clip
2997-04-272 Flex Clip Reducer, Threaded Insert
2997-04-275 Flex Clip Reducer, Handle
Should screw crowding require the removal of a EXPEDIUM
VERSE Screw’s extended tabs prior to insertion or a tab
prematurely break, a Flex Clip Reducer has been included in
the system.
This instrument is comprised of three parts: the Flex Clip, the
Threaded Insert (two-part assembly), and the Handle. Start by
assembling the two components of the Threaded Insert as
shown.
(FIGURE 64)
Next, compress the proximal end of the
Flex Clip to open the distal end. Place over the TOP NOTCH
Feature and allow distal end to engage. If the Flex Clip has
properly engaged the TOP NOTCH Feature, slight rotational
or pulling forces should not displace the instrument.
Next, grasping the hex end of the Threaded Insert, insert it
into the Flex Clip. Rotating the Threaded Insert in the
clockwise direction will engage the threaded mechanism and
translate the component distally. Once the instrument has
contacted the rod, place the Flex Clip Reducer Handle onto
the hex of the Threaded Insert and rotate clockwise to
continue reduction.
Care should be taken to distribute reduction forces by
utilizing a staged reduction process which involves
incremental reduction across multiple levels.
Markings on the side of the flex clip indicate the amount of
reduction required. Once reduction marker is aligned with
zero “0” the rod has been fully reduced.
To retain reduction, insert a Correction Key or Unitized Set
Screw through the Flex Clip Reducer.
The Flex Clip Reducer can be removed by unthreading the
Threaded Insert and compressing the Flex Clip to disengage
the TOP NOTCH Feature.
