• Orient the heel wedge (Fig. 3, Pos. F) for insertion so the locking recess (Fig. 3, Pos. L) in the
wedge is positioned in the proximal and posterior direction.
• Slide the heel wedge into position from the posterior side of the prosthetic foot between the
attachment spring (Fig. 3, Pos. D) and heel spring (Fig. 3, Pos. B).
INFORMATION
• The heel wedge is properly installed when the locking recess (Fig. 3, Pos. L) in the heel wedge
is fully seated around the mating stop (Fig. 3, Pos. K) on the attachment spring.
• The heel wedge is designed such that no adhesive is required to affix it to the prosthetic foot.
4.2.3 Removing a heel wedge
INFORMATION
The heel wedge has a tendency to rotate during removal. Pulling the heel wedge in the direction
of rotation helps make the removal easier.
• Push on the medial or lateral side of the heel wedge with your finger to free it from the mating
stop (Fig. 3, Pos. K) on the attachment spring (Fig. 3, Pos. D).
• After the heel wedge is partially free grab it by the respective lateral or medial side and pull it
free from the prosthetic foot.
4.3 Selecting and Adjusting the Functional Ring
The 1C61 Triton Vertical Shock is delivered as a complete foot assembly. The stiffness category
of the functional ring is synchronized with the weight category of the foot assembly. If during wal-
king too much compression of the functional ring is observed, an exchange to a stiffer functional
ring can be done.
NOTICE
Function loss as a result of improper use. The Functional Ring may only be selected/adjusted
by prosthetists that have been authorized by Otto Bock.
4.3.1 Selecting the right Functional Ring
Use the following selection table to select the right Functional Ring. The Functional Ring version
is marked on the backside of the functional ring.
