or narrow the width at the knee, the 6 mm (1/4") padding located under
each cover can be removed and replaced with thinner pads [3 mm ("1/8)
or 1,5 mm ("1/16)] or you can install a shim behind the 6 mm (1/4")
pad to make the fit more snug. Any combination of pads can be used to
achieve a more comfortable fit.
To accommodate subtle variances in the plane of the patient's leg, the
anterior tibial strap (ATS) (figure 5) should be loosened or tightened as
needed so that the center of the hinges is slightly posterior of the
midline. In conjunction, adjust the lower strap and the bottom strap.
If the brace is too far anterior, loosen the tibial alignment strap and
tighten the lower and bottom straps. If the frame is too far posterior,
loosen the lower and bottom straps AND tighten the tibial control strap.
Accurate planar setting will help to ensure optimal brace suspension.
Adjusting fit at the tibial horseshoe:
Tibial wedge pads can be installed to fill in any gaps around the tibia
(figure 6) and achieve the desired fit. To add a wedge pad, pull back the
silicone liner and place the proper wedge pad (medial or lateral) on top
of the hook-and-loop fastener to which the silicone liner was originally
fastened (figure 7). Press the silicone liner back into place on top of the
wedge pad. Fine tune the padding until your CTi OTS brace fits snugly
against the tibia (figure 8).
cHANGING ExTENSION STOPS
Extension stops are available for varying degrees of extension control.
1. Remove the cover and pad from the condylar area.
2. Using a short Philips head screwdriver, remove the screw in the
center of the hinge plate (figure 9).
3. Locate the extension stop positioned in the hinge between the up-
per and lower arms of the brace. With brace slightly bent, push the
extension stop from the back of the brace through to the front. This
should cause the stop to pop out of the hinge (figure 10).
4. From the bag of extension stops included with the brace, choose the
stop which corresponds to the desired degree of extension. Feed the
hole end of the stop through the hinge from the front to the back of
the brace, with the curved side facing down and the flat edge facing
up. Make sure that the sharp extrusions on the flat end of the exten-
sion stop are pointed toward the distal portion (bottom half) of the
brace (figure 10). The flat end of the stop should be visible from the
front of the brace.
5. Align the hole in the center of the hinge plate with the hole in the
extension stop. Replace and tighten the screw through the hinge
plate and extension stop. Replace the pad and cover. This procedure
must be completed on both the medial and lateral hinges.
6. Choose the appropriate extension stop (Blue = 0°, Black = 0-10°,
Dark Gray = 10-20°, Medium Gray = 20-30°, Light Gray = 30-40°)*
• These numbers are approximate. Actual extension stop will vary from
person to person depending on anatomical differences. Appropriate
extension stop size is normally determined by health care provider.
