NOTE: Have patient wear brace for a few minutes to make sure straps
are at comfortable tension.
DONNING BRACE
1. Align brace on patient´s leg with center of hinge at mid patella and
midline of a / p plane (Figure 1).
2. With both Quick Fit Buckles open - place button of lower Quick Fit
Buckle into appropriate keyhole above buckle-stability pin (Figure
2) and close carefully (Figure 3). The button is now color matched
with an identical blue color swatch in the keyhole for intuitive strap
selection.
3. Bend knee to an 80° angle - foot flat on floor.
4. Place button of upper Quick Fit Buckle into appropriate keyhole
(yellow) and close carefully.
5. Tighten Dynamic Force Control System to a prescribed position
(Figure 4): Practitioner will need to determine optimum unloading
based on patient´s pain relief feedback but initial setting is
recommended at 5.
6. Fully extend leg in a sitting position and make sure that brace is still
aligned correctly on leg.
7. Ensure strap pad is not wrinkled and is positioned under strap
crossing in popliteal. Quick Fit Buckles may have to be opened to
relieve strap tension and allow positioning of strap pad on non-
ratcheted DFS strap (Figure 13).
8. 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.
9. If Dynamic Force Control System has been pulled to its maximum
and patient requires more pain relief, DFS straps need to be
shortened accordingly on lower Quick Fit Buckle.
