Plantar/dorsi flexion
•
Heel flexibility
The dynamic alignment is performed in accordance with good professional practices.
9. ASSEMBLY
Highlander feet are pre-assembled and consist of a foot module, a Spectra sock, and a foot shell. After dynamic alignment, tighten
the pyramid adjustment screws according to the specifications of the connector manufacturer. Secure pyramid adjustment screws
with a thread locking adhesive (i.e., Loctite 242).
Spectra sock
A Spectra sock is included to protect the foot shell and minimize noise. It must be placed on the foot module before mounting the
foot shell.
Foot shell
To install and remove the foot shell, use the foot shell removal tool to prevent damage of the foot module.
Never remove the foot from the foot shell by pulling manually. This could damage the foot.
10. ADJUSTMENTS
The heel stiffness at foot loading can be adjusted using the stiffening bumpers. The bumpers may be temporarily attached using
the pre-applied adhesive in the location indicated in the table below. The recommended location will stiffen the heel of about 1
category. If necessary, move the bumpers anteriorly (stiffer) or posteriorly (softer) to get the desired stiffness. For permanent
placement, clean off the pre-applied adhesive with acetone and adhere bumpers using cyanoacrylate glue.
