Ottobock 1C61 Triton Vertical Shock Instrucciones De Uso página 22

• Use the 2C100 Footshell Insertion/Removal tool provided by Otto Bock to insert the carbon
foot into the footshell.
• Make sure that the heel of the polymer base spring locks in under the footshell heel tab.
Removing the footsell:
• Insert the 2C100 Footshell Insertion/Removal tool under the heel of the polymer base spring
which is located under the heel tabs in the posterior part of the footshell and pry the heel out
of the shell. It is then possible to pull the foot out of the footshell.
4.1.2 Bench alignment (Foot with footshell)
Recommendations on bench alignment (foot with footshell):
Foot size (cm)
21–22
23–24
25–26
27–28
29–30
4.1.3 Static alignment optimization
The prosthesis should be aligned with the L.A.S.A.R. Posture, if available. The Otto Bock recom-
mendations on alignment of transtibial and transfemoral prostheses should be observed.
4.1.4 Dynamic alignment optimization
Adapt the prosthetic alignment in the frontal plane (ML) and in the sagittal plane (AP) by angle
adjustments and/or sliding adjustments, in order to ensure correct heel contact, easy roll-over,
and optimal shifting of weight onto the contralateral side. For transtibial amputees please make
sure that there is physiological knee flexion during stance phase.
4.2 Using the optional heel wedges
CAUTION
Risk of falling due to change of the knee dynamics when using heel wedges.
The use of heel wedges can facilitate stance phase flexion when bearing weight on the prosthesis.
Therefore, particular caution is advised during the dynamic alignment optimization – especially
when a knee joint without stance phase control is used.
4.2.1 Heel wedge application
Two heel wedges are included to each 1C61 Triton Vertical Shock prosthetic foot:
• „Soft" Heel Wedge: translucent
• „Stiff" Heel Wedge: graphite color
Should the patient feel the heel strike too soft or the knee in hyperextension during the mid-stance
phase, the heel can be stiffened by using one of the two heel wedges.
4.2.2 Inserting a heel wedge
INFORMATION
Otto Bock recommends to test the foot first without using a heel wedge.
