8. Fully extend leg in a sitting position and make sure that brace is still
aligned correctly on leg (Figure 4).
9. Ensure strap pad is positioned under strap crossing on non-
ratcheted DFS strap in the popliteal and not wrinkled. Quick Fit
Buckles may have to be opened to relieve strap tension and allow
positioning of strap pad on non-ratcheted DFS strap. Remove
Upper DFS strap with dosing ratchet and feed strap through strap
pad (Figure 5).
10. If patient requires more or less unloading, adjust the tension of
upper DFS strap accordingly with Dynamic Force Control System
and/or lower DFS strap by adjusting length at thigh Quick Fit
Buckle.
11. If Dynamic Force Control System has been pulled to its maximum
and patient requires more pain relief, DFS straps may require
shortening at the lower Quick Fit Buckle.
12. Keyhole locks may be inserted into calf and thigh shells if desired to
ensure straps cannot accidentally be disengaged from shells
(Figure 6).
NotE: Have patient wear brace for a few minutes to make sure straps are
at comfortable tension.
