Runway® HX Instruction for Use
Weight Line
Product Number: RS2-K1
Product Description The Runway® HX is a carbon f iber adjustable heel height prosthetic foot . Its anatomical
gliding ankle m aintains app r opriat e f oot alignment to prov ide k nee s ta bi lity and consistent
performance at all heel hei ghts. The Runway® car bon fiber material s tores and returns
energy so that users can walk farther, faster, longer. The Runway® fiber layers are tailored
to an individual’s body weight and impact level, providing a customized product for superior
comfort.
Bench Alignment Prior to donning the prosthesis:
Plantarflex/Dorsiflexion foot to match the shoe heel height. (See Operation Sectio n)
•
Adduct/Abduct socket to provide appropriate frontal plane angle.
•
Flex/Extend socket to provide appropriate sagittal plane angle.
•
Move the socket to ensure the weight line falls along the anterior edge of the pylon (see
•
illustration).
Dynamic Alignment To optimize the heel to toe rollover motion, adjust the following variables:
Anterior/posterior foot placement
•
Dorsiflexion/plantarflexion
•
Heel stiffness
•
Heel Stiffness Heel too soft Symptoms
Heel too hard Symptoms
Toe Stiffness
Toe too stiff Symptoms
Toe too soft Symptoms
Foot flat occurs too rapidly
•
Toe feels excessively stiff
•
Knee hyperextension
•
Solutions
Shift socket anteriorly in relation to the foot
•
Attach rubber stiffening bumpers
•
Rapid knee flexion, instability
•
Heel to toe progression too rapid
•
Lack of energy return sensation
•
Solutions
Shift socket posteriorly in relation to the foot
•
Verify appropriate foot module category
•
Flat spot in rollover motion at slow cadences
•
Solutions
Consider a lower category foot module
•
Clicking noise at initial contact
•
Excessive toe deflection with high impact activity
•
Solutions
Consider a higher category foot module

Operation
•
Insert a 4mm hex key (provided) through the posterior foot shell into the ankle
mechanism.
•
To increase the foot height, turn the hex key clockwise.
•
To decrease the foot height, turn the hex key counterclockwise.
•
Remove the hex key prior to allowing ambulation.
Operation
•
Your prosthetist m ay let you use t he pr osthes is with out a foot shell f or a s hort per iod
pylon in the correct vertical orientation .
•
Inform your prosthetist if the toe and heel of the foot do not feel balanced.
•
For best result, be seated in a chair to adjust the heel height.
•
Do not attempt to adjus t the ankle while standing without using a grab r ail or other
appropriate fixed object for support.
•
Insert a 4mm hex key (provided) into the back of the foot shell.
•
To increase the foot height, turn the hex key clockwise.
•
To decrease the foot height, turn the hex key counterclockwise.
•
Fourteen turns will change the heel height by one inch.
•
The wrench must be removed from the ankle before placing weight on the foot.
Maintenance
The ankle mechanism requires periodic maintenance.
ankle shims adjustment will be required by the prosthetist.
Product Number: RS2-K1
Stiffening Bumpers Rubber stiffening bumpers are included to adjust the heel stiffness during loading
response. The bumpers may be temporarily attached between the heel lever and the keel
using the pre-applied adhesive in the location indicated on the bumper package to increase
heel stiffness one categ ory. If the he el stif fness is too stif f, move the bumper posteriorly;
too soft, move it anter iorl y. For per m anent plac em ent, clean off the pre-applied adhesiv e
with Acetone, and adhere bumpers using Super Glue (cyanoacrylate).
Spectra™ Sock Replace Spectra™ soc ks at inter vals appropr iate to the us er’s activit y level to protect the
foot shell and m inimize noise. Failure to inspect and replace the Spectra™ socks may
prematurely wear the foot module.
Foot Shell Use the Foot Shell Remova l T ool (ACC -00-10200-00) to insta ll or remove the foot shell to
prevent damage to the foot module.
