Instructions for Use
Product Number: ROM-00-XXXXX-XX
Introduction
The Kinterra
™
foot/ankle system combines hydraulics and carbon fiber, to provide
low to moderate impact K3 ambulators an exceptionally normal walking gait
–
regardless
of surface angle or speed. The result is rock solid stability and the confidence for users to
choose their own path.
Articulated ankle movement provides 12 degrees of motion, with adaption to
slopes for improved stability and overall comfort.
An innovative Dorsi-Assist Spring assists toe clearance to prevent stumbles and
falls.
Precision controls are easily accessible, making the set-up fast and efficient.
The design uniquely delivers gait simulating biological norms on both slopes and
level ground for superior stability.
Patient Selection
The Kinterra
™
is intended for use by low to moderate impact transtibial and transfemoral
K3 level ambulators. It is recommended for unilateral use. Caution should be used when
fitting bilateral patients due to the added movement of the ankle. Kinterra has a weight
limit of 275 lbs. (125 kg).
Assembly
The Kinterra foot/ankle system is pre-assembled consisting of a foot module, ankle unit,
Spectra
™
sock and foot shell. After dynamic alignment, torque pyramid adjustment
screws to
the manufacturer’s specifications. Secure
pyramid adjustment screws with a
thread locking adhesive (i.e., Loctite 242).
Alignment
Bench Alignment
With a
3/8” (10mm) lift under the heel or the foot placed in the desired shoe, use a plum
bob or laser to confirm that the weight line falls through the anterior aspect of the pylon
and pyramid.
Static Alignment
To complete the static alignment, stand the patient in a set of parallel bars. The patient
should be able to stand comfortably without feeling as if the knee is flexing or
hyperextending. If the knee is flexing, slide the foot anteriorly. If the knee is
hyperextending, slide the foot posteriorly.
