Alternative Function For Neuro Flex Max Lock Function/Step Lock Function; Limitation Of The Maximum Knee Flexion Angle - FIOR & GENTZ NEURO LOCK Gebrauchsanweisung

The extension stop and the flexion stop must always match each other.
After replacing the extension stop (fig. 4), the flexion stop must be filed
according to the chosen degree. For this purpose, you will find auxiliary
lines on the flexion stop (fig. 3/B).
If you wish to use the system joint with a smaller flexion than
the one you have already filed, you must mount a new flexion
stop disc or a new joint's lower part.
Step Lock Function
The system knee joint with step lock function is a joint that locks
gradually during extension. The toothings of the step lock stop disc
and the step lock pawl enable the gradual locking of the system joint
in 10° steps up to a maximum of 55° or 60° (fig. 5). The extension stop
can be exchanged depending on the desired extension (see paragraph
Extension Stop und Flexion Stop).
A 5° extension stop and a 5° step lock stop disc are premounted
in the system knee joint with step lock function. All other exten-
sion stops require a 0° step lock stop disc.

Alternative Function for NEURO FLEX MAX Lock Function/Step Lock Function:

Limitation of the Maximum Knee Flexion Angle

With the flexion stop disc AF you can limit the maximum knee flexion angle when the system joint is unlocked.
Converting the System Joint into Alternative Function
1 NEURO FLEX MAX Lock Function: Exchange the premounted
flexion stop disc and cover plate for the flexion stop disc AF and
cover plate AF.
NEURO FLEX MAX Step Lock Function: Exchange the premounted
step lock pawl, step lock stop disc and cover plate for the locking
pawl, flexion stop disc AF and cover plate AF.
2 Set the desired maximum knee flexion angle of 60°, 70°, 80° or 90°
by filing. To do so, use the auxiliary lines on the flexion stop disc AF
(fig. 6).
The extension stop can be exchanged depending on the desired exten-
sion (see paragraph Extension Stop und Flexion Stop).
