Why a custom articulating limited ROM AFO is used for this pathology: Western Carolina O&P designs and fabricates this type of AFO specifically tailored for this common pathology for superior subtalar triplanar control and foot ankle alignment support. Our practitioners start with a comprehensive foot and ankle evaluation of the mechanical and fitting perimeters, and once defined, a design plan for the custom AFO is established. A negative mold impression, or digital scan is taken of the patient affected lower extremity so a custom AFO can be fabricated. Western Carolina O&P, with our state of-the-art fabrication lab, produces a structural supportive and comfortable device to support the proper foot structures, provide adjustable ROM, and hind foot stability to restore dynamic gait mechanics for safe ambulation and joint stability. This custom fabricate AFO is designed to be light weight and strong. Because it is custom fabricated to a positive model all abnormal structural changes that usually accompany PTTD and AO can be accommodate. Articulating AFO’s that provide a limited ROM window are able to maintain proper three rocker gait mechanics by allowing plantar flexion and dorsi flexion during the gait cycle. Patient are able to articulate with in a ROM perimeter that lessens joint degradation while maintaining movement. This not only helps the patient with increased safe ambulation, but also helps to relieve upper kinetic chain joint forces and improve body alignment. Articulating braces provide for joint ROM that will encourage muscle and connective tissue usage to help maintain joint health.
Orthotic specific design consideration: This custom AFO is designed and fabricated in either a carbon fiber frame with semi-flexible plastic foot plate, or all plastic. Because the AFO is built from a modified positive mold of the patients’ lower extremity, a total contact device is produced. The total contact fit and use of limited ROM joints make for a very comfortable and functional brace. This type of AFO uses a special adjustable plantar and dorsi flexion stop joint for motion control to accommodate each specific patient’s bio mechanical needs. This design provides proper mechanical foot and ankle control and support though out the gait cycle.
Rx: consideration: On our AFO orthotic specific Rx sheet for physicians, please mark for “CUSTOM PTTD / OA AFO” and the specific Dx. Once we have seen and evaluated the patient we will request your face to face progress note and send a CMN for signature and date.
