Heel too hard
Symptoms
• Rapid heel to toe movement
• At initial contact the amputee has poor control of his prosthesis
• Minimal energy return feeling
• Knee may become unstable
Action
• Replace heel wedge with a smaller one
• Shift socket posterior (or foot anterior).
HEEL WEDGES CM150011 (Figure 4)
The wedge can influence the heel to toe function. Start altering the heel
resistance to improve foot response by adding a heel wedge. The 2°, 4° &
6° wedges can be interchanged to customize the stiffness and achieve
the desired functional characteristics. A combination of wedges may be
used
1. 2° – yellow
2. 4° – red
3. 6° – blue
Temporary Wedge Placement
• Cut the wedge to the width of the foot module.
• Roughen the upper and lower surface of the wedge with abrasive
paper.
• Place the wedge in the angle of heel and foot module.
Note: Do not force the wedge into the junction of heel and foot module.
• Secure in position bond to upper surface (Figure 4) with tape wrapped
around the foot module (Figure 5).
Permanent Wedge Placement
• Apply adhesive on the upper side of the wedge only.
• Locate in the foot/heel junction and position before adhesive sets.
Instant adhesive is necessary to bond the urethane heel wedge.
The adhesive cures in 15-20 seconds. For removal the adhesive may be
softened by soaking in acetone or cyanoacrylate adhesive remover.
HEEL ASSEMBLY

for corrosion and sign of wear. Replace bolts if needed.
SPECTRA SOCK FCX63008
To protect the cover and avoid noise a spectra sock is fitted over the foot
module before installing the cover. The sock should be loose in the heel
area and secured proximally with the cable tie provided.
