Dynamic Alignment - Össur LP ROTATE VLXExxyyz Instrucciones De Uso

ROD REPLACEMENT
The LP Rotate™ shock module contains an inner rod, which varies in
density in order to control the vertical travel. This inner rod can be
exchanged or replaced to customize the amount of the travel for patients
of different weights. Compression restistance can be adjusted by
following the rod adjustment.
1. Unscrew male or female pyramid adapter
2. Unscrew adjustment plug using a 6mm hex
3. Replace the inner rod
4. Ensure adjustment plug is in contact with inner rod.
5. Torque the pyramid adapter (Figure 5) to specifications.
6. The pyramid clamp must be positioned anterior (never medial
or lateral).

DYNAMIC ALIGNMENT

The heel stores energy after initial contact, slowly releasing it at
midstance. The forward momentum generated by this action results in
the toe being loaded for optimum energy release at terminal stance. The
heel to toe action can be influenced by:
• A-P positioning of foot
• Dorsi-Plantarflexion
• Heel Stiffness
• Adjusting the inner rod
• A soft rod can lead to the foot feeling too stiff. Upgrading the rod will
transform the flexibility of the foot.
• Check for shock module action and assess vertical displacement.

HEEL STIFFNESS
Heel too soft
Symptoms
• Foot will come to flat position too early (amputees will feel like
sinking into a hole).
• Extra energy is required to climb up over the toe.
• Toe will feel too stiff.
• Knee may hyperextend.
Action
• Add polyurethane heel wedge.
• Shift socket anteriorly (or foot posterior).
Heel too hard
Symptoms
• Rapid heel to toe movement
• At heel strike the amputee has poor control of his prosthesis
• Minimal energy return feeling
• Knee may get unstable
