The
Wheaton™ Bracing System (KAFO)
for Metatarsus
adductus/varus, Clubfoot,
and Tibial
Torsion
Product
Description
The
KAFO consists of the Wheaton™ Brace AFO connected
to a thermoplastic upper component (Knee extension,
KO) with touch fasteners. The upper component is designed
to keep the knee flexed at 90° flexion. When used
with the lower component (AFO), it allows for torque
correction of tibial torsion, applying a direct corrective
rotational force on the tibia without any torque on
the femur or hip. By overlapping the two components
and using touch-fasteners, infinite positions of adjustments
can be made to determine the amount of torque desired
and the growth of the leg during correction. Specify
left, right, or pair when ordering.

The Wheaton™
Bracing System is an innovative and cost-effective device for the treatment
of intoeing disorders in infants and young children. It is a ready-made
thermoplastic device that comes in several sizes to fit children from
birth to 4 years of age. The device comes in two components:
- The
lower component (Wheaton Brace, AFO) is
designed to apply a 3-point correction for the adductus/varus foot.
It comes in two series - the MTA series with the ankle at 15° plantarflexion
to prevent iatrogenic heel valgus during correction in the younger infant,
and the TEV-CRB series with the ankle at 90° dorsiflexion (neutral
position), necessary for the infant with clubfoot, and toddlers.
- The
upper component (Knee extension, KO) is designed to keep the knee
flexed at 90° flexion, and when used with the lower component (AFO)
allows for torque correction on the tibial torsion. By overlap of the
two components and use of touch-fasteners, infinite positions of adjustments
can be made to determine the amount of torque desired and the growth
of the leg during correction.
Indications
For Use
I. Metatarsus
Adductus/Varus (MTA)
The device is used for the primary correction of MTA, in place of serial
castings and corrective shoes, or for the maintenance of correction after
castings. Either the MTA or the TEV-CRB series may be used, depending
on the preference of the physician. The MTA series is available from birth
to 8 months of age. The TEV-CRB series is available from birth to 4 years
of age. While the lower component alone is effective in most cases, some
physicians may prefer to add the upper component for better control of
the leg (see III).
II.
Congenital Clubfoot
The device is used for the maintenance of correction after castings or
surgery for clubfoot, by controlling forefoot adductovarus, hindfoot varus,
and ankle equinus. The TEV-CRB series should be used. The upper component
is optional, depending on the severity of the residual ITT (see III).
III.
Internal
Tibial Torsion
The device is used for the primary treatment of persistent tibial torsion
in children up to age 4, in place of the D-B bar. For ITT, both upper
and lower components are used together.

For
insurance billing, the suggested HCPCS Code for the lower component (AFO) is L1930* and
L1836 for the upper component (KO).
*L2820 in addition to L1930 may also qualify for many plans. Please check with a coding advisor before adding.
