3. Fill in the patient information table on the alignment sheet (Figure 6)
a. The socket adduction can be observed by looking at the original
walking prosthesis in the frontal plane.
b. Use the angle guide on the A1 alignment sheet to help measure the
foot rotation in relation to the socket.
4. Attach Sole and Heel counter (Figure 7)
a. Glue the heel counter onto the upper surface of the heel, aligning
the center line with the split in the carbon heel.
b. Glue the sole onto the underside of the foot, again aligning the
center line with the splits in the carbon fiber.
c. Grind the sole and heel into a shape that gives a good fit in the
patient's shoe. Use the sole template on the back of the product
box.
5. Cut the pylon to length (Figure 8)
a. Align the new socket and the foot with the tracing of the original
prosthesis.
b. Mark the pylon at the height of the posterior brim of the socket
using the drawing of the original prosthesis.
c. Cut the pylon at this mark and round off the end, removing any
sharp edges.
6. Mark the length of the attachment surface on the foot pylon (Figure 9)
a. Mark the pylon at 90mm from the top (cut end).
b. Roughen all the surfaces of the pylon above this mark (shown by
grey area).
7. Align the foot and the socket with the tracing of the original walking
prosthesis (Figure 10)
a. The sole should be lined up with the outline of the foot cover sole.
b. The new socket should be positioned over the tracing of the original
socket with additional 5-7° of knee extension in the socket.
c. Use a foam spacer/s (or other spacer) placed between the pylon
and the socket to maintain the correct extension. Spacers should be
placed at the end of the roughened attachment surface. Ensure the
minimum clearance of 5 mm is maintained between the distal
posterior area of the socket and the foot pylon.
d. Any spacer used at the top of the pylon can have maximum
thickness of 5 mm.
e. Fasten the foam to the foot using tape.
f. Mark a clear height on the socket at height of a foam spacer on the
pylon.
8. Align the socket according to the patient information (Figure 11)
a. Put the shoe on the foot and place it upright in the work surface.
b. Hold the socket in positon on the pylon according to:
– The height
– The recorded socket adduction
– The recorded foot rotation in relation to socket (using angle
guides on A1 sheet)
c. The foam spacers will hold the socket in the correct extension.
9. Mark the attachment surface onto the socket (Figure 12)
a. Holding the socket in the desired position, trace around the end of
the pylon onto the socket above the height mark.
