Transtibial Bench Alignment
The socket should be set with the proper amount of inset found in the evaluation.
A plum line from the bisection of the socket at the proximal brim in the frontal and
sagittal plane should bisect the ankle pyramid. The foot may be slightly inset, 1–12
mm, depending on the limb length. Short limb lengths are set with very little inset of
2–3 mm and longer limb lengths may tolerate a greater varus thrust of 10–12 mm.
The longitudinal axis of the foot will be outset approximately 5° by aligning the medial
border of the foot with the line of progression.
Transfemoral Bench Alignment
Alignment at the transfemoral level should be consistent with the instructions
provided by the manufacturer of the prosthetic knee in use.
Dynamic Alignment
The Aeris Performance 2 foot is flexible and conforms to uneven terrain. This
characteristic may mask forefoot loading anomalies during static alignment that may
then become more noticeable during dynamic alignment. Small alignment changes will
smooth the transition from heel to toe and optimize gait. Patient feedback during this
process is essential. Adjustments of the plantar and dorsiflexion angles will help the
patient achieve a smooth transition from heel to toe. The pylon should remain vertical
in the frontal plane throughout gait.
Procedure
• Check for smoothness of gait and ground contact throughout the stance phase of
gait .
• If the tibial progression is slowed from heel strike to midstance, or the heel
compression is too great, moving the socket anteriorly or dorsiflexion of foot may
correct this problem .
• If the socket progresses rapidly forward from heel strike to midstance or the heel
seems too hard, moving the socket posteriorly or plantarflexion of the foot may
solve this problem .
• If the foot progresses too quickly from midstance to toe loading, moving the socket
posteriorly or increased plantarflexion may resolve this issue.
• If the foot hesitates from midstance to toe loading, moving the socket anteriorly or
dorsiflexion may be indicated.
• Check to make sure the pylon is vertical throughout gait. If there is a medial lean,
tighten the proximal medial screw; if there is a lateral lean, tighten the proximal
lateral screw.
If a smooth stance phase of gait cannot be achieved, contact Fillauer for additional
