Otto Bock 17AD100 10 Instructions For Use Manual page 37

14) Position the washer (item 5) on the spring holder (see fig. 30).
15) Insert the spring dummy (item 3) into the module (see fig. 31).
16) Place the spring bolt (item 2) on the module and fasten it with a Torx
wrench (see fig. 32). The spring dummy must fit in the module without
play.
17) Put the orthosis on the patient (see fig. 33).
See the illustration of the reaction module for the corresponding wrench
sizes and tightening torque values (see fig. 7).
Reaction module – static trial fitting
Required materials: 643A8 knee pivot point gauge
>
Prerequisite: The reaction module is mounted to the spring dummy in
>
the ankle joint.
1) Put the orthosis on the patient (see fig. 33).
2) Use the knee pivot point gauge to mark the compromise pivot point
according to Nietert on the knee joint (see fig. 34).
3) Guide the Torx wrench through the spring bolt (see fig. 35) and adjust
the stop pin (see fig. 7, item 10) to change the angle of the upper ankle
joint. Relieve the lower leg by hand so that the stop pin moves easily in
the thread (see fig. 36).
4) Readjust the stop pin if necessary so that the orthosis does not have any
play in the anterior/posterior direction.
5) Check the static alignment of the orthosis using the L.A.S.A.R. Posture
(see fig. 37).
Reaction module – dynamic trial fitting
Required
>
17AD100A=HS-*-2 spring (extra strong)
Prerequisite: The reaction module is mounted to the spring dummy in
>
the ankle joint.
1) The spring dummy must be removed and replaced with the reaction
spring prior to the dynamic trial fitting. Use a Torx wrench to loosen the
spring bolt (see fig. 7, item 2) and remove it from the module.
2) Remove the spring dummy (item 3) and replace it with the reaction
spring (item 4) (see fig. 38).
3) Screw in the spring bolt flush with the cover (see fig. 39, see fig. 40).
4) Put the orthosis on the patient and perform a fitting.
5) Check the sagittal alignment of the patient on the L.A.S.A.R. Posture.
6) Set the desired pretension of the spring (see fig. 41).
7) Have the patient walk while wearing the orthosis.
