As a proprietary injection-molder for
KLM Laboratories Inc., PFI manufacturers the CP-3300, an injection-molded
polypropylene orthotic, System_Rx custom orthotic shells, and Kiddythotics,
orthotics for children.
CP-3300
The proprietary CP-3300 shell is an injection-molded
polypropylene orthotic that emulates the contours and function of custom-made foot
orthotics. The CP-3300 Insole adds further advantages to the Shell by including a
full-length, 1/8" Super-All-Step top cover.
System_Rx
System_Rx evolved through a study of the mathematical
relationships between the shape of the foot in it's neutral position in the negative cast,
and it's corrected shape in the positive mold. These relationships are usually achieved by
technicians trained in the art of biomechanics.
Mathematically, the foot is a measurable blend of three
dimensional shapes, beginning with the neutral, negative cast, and ending with the
corrected positive mold. The measurable difference between the two are the corrected
deformity (intrinsic balancing) and the medial and lateral expansions. Simply, if the
negative cast and the corrections are both measurable, then it is posible to predetermine
the corrected shape of the positive mold and the resulting orthotic.
System_Rx takes the cast data, adds in the mathematical
corrections required for each patient according to the prescription of the physician, and
searches our library of thousands of pre-defined shapes. The computer identifies the
appropriate shape, and a 3-D CAD/CAM mill generates the corrected positive mold.
The Result
Further study of over 133,000 pairs of orthotics shows
that certain foot shapes are used much more often than others. Of the multiple shapes in
the system, 61 shapes occurred 70% of the time.
Most feet fall into a relatively small range of
measurable dimensions. By example heel widths range from 47mm to 72mm, medial arches at
their apex along the 1st metatarsal shaft range from 14mm to 23mm in height, and foot
length from the posterior heel to the bisection of the 1st metatarsal head range from
148mm to 198mm (shoe sizes 6-12).
The Product
Value System_Rx is these
sixty-one shapes injected molded into 4mm rigidity polypropylene sport orthotics.
Value System_Rx is the new
standard for consistent quality in functional orthotics.
Value System_Rx reduces orthotic
costs.
