6.1 Adapting the Protector

6.1.1 Shortening the Protector – Preliminary Shortening
1) Remove the prosthesis from the residual limb.
2) Remove the shoe from the prosthetic foot.
3) Loosen the foot connection cap of the prosthetic foot.
4) Check whether the closures on the protector are properly fastened and the protector is not
twisted.
5) Lay the protector next to the prosthesis.
INFORMATION: Make sure that the knee plateaus of the knee joint and protector are
at the same level (see Fig. 1).
6) Mark the protector distally at the level of the foot contact surface (see Fig. 2).
INFORMATION: For tall patients, shortening the protector may not be required.
7) Make another mark 1 cm above the existing mark.
8) Apply crepe adhesive tape proximally all around at this mark.
9) Use a vibrating or band saw to shorten the protector along the bottom edge of the crepe
adhesive tape.
6.1.2 Shortening the Protector – Final Shortening
1) Remove the crepe adhesive tape and lengthwise closure from the protector after preliminary
shortening.
2) Open the upper closure on the protector.
3) Spread open the protector and apply it to the knee joint (see fig. 4).
INFORMATION: The retainers of the protector (at the side in the upper closure area)
have to engage on the frame element of the knee joint (see fig. 5).
4) Fasten the upper closure on the protector.
→ Slightly squeeze the protector together with both hands.
5) Depending on the size of the chosen foot cuff, mark the following distances in at least 3
places on the protector (see fig. 6):
INFORMATION: The distances have to be measured respectively from the foot contact
surface, creating a cut edge parallel to the foot contact surface. This makes for an
optimum overlap of the foot cuff over the protector main unit.
• Size S: 110 mm
• Size M: 120 mm
• Size L: 125 mm
6) Remove the protector.
7) Fasten the upper closure (see fig. 14) and lengthwise closure (see fig. 7).
8) Tape off the protector with crepe adhesive tape above the mark.
