Valgus frame filler - lateral frame filler

About:
The valgus frame filler (lateral frame filler) is semi-rigid to very rigid (45-65 Shore A) EVA material added to the inferior lateral side of an orthotic frame. It begins at the distal rearfoot, extends distally through the midfoot and tapers to the distal edge of the frame, proximal to the lateral metatarsal heads.

Orthotic Lab Codes:
VGFF: VG Lateral Frame Filler

*CLINICAL PEARL
Extrinsic rearfoot posts matching in angulation are recommended, but not required (e.g., for clinically controlling an everted subtalar joint and inverted midfoot, a varus rearfoot post with a valgus frame filler is acceptable. These modifications will create a “twist” or alternating pressures along the foot’s sagittal plane when the orthotic reaction forces interacts with the foot).

Medial Frame Filler

About:
A medial frame filler is added to the plantar, medial surface of the frame and fills the void between the plantar surface of the orthotic frame and the shoe. A medial frame filler stiffens the medial arch and reduces deflection of the medial arch of the orthosis.

Myolite or EVA reinforcement and shock absorbing layer inferior of frame

About:
Frame filler is flexible, semiflexible or rigid (15, 30 or 65 Shore A) Myolite or EVA material added to the inferior medial and lateral arch area of a device’s frame. On an extrinsic device, it begins proximally at the device’s distal rearfoot and extends distally, tapering to the frame’s distal edge.

On an intrinsic device the frame filler will extend around the entire heel cup area. This modification creates a flat inferior surface for the device to sit level. A filler skive can be modified to further customize the frame filler.

Inferior removal of frame filler to accommodate shoe gear and/or reduce filler function

About:
A filler skive is the removal of the frame filler that sits beneath the device’s medial arch. The removal of frame filler begins medially at the inferior distal rearfoot and extends distally in a circular curvature, terminating proximal to the medial distal edge of the frame. The apex of the circular shape does not pass the device’s sagittal plane and imitates the negative space of a patient’s plantar arch area.

• Max skive bisects the 3rd metatarsal shaft
• Medium skive bisects the 2nd metatarsal shaft
• Minimum skive bisects the 1st metatarsal shaft
