Topcover
Any material used to act as an interface between the device and the foot. It is intended to cushion, finish or give the orthosis better wear resistance.
Resource Type: Definitions
Sweet Spot
A pocket pressed into an orthotic shell and filled with Poron to accommodate a plantar prominence. It is commonly used to accommodate a prominent navicular tuberosity. Only available on vacuum-formed
1st Ray Cut-out
The medial corner of the orthosis plate is removed starting distally from the 1st intermetatarsal space and extending proximally to the 1st metatarsal base. The intent is to further plantarflex
Plantar Fascial Groove
A groove pressed into the orthosis to accommodate a prominent plantar fascia. This can only be fabricated on a vacuum-formed orthosis.
Medial Flange
An increase in the height of the orthosis on the medial side of the device starting just distal to the heel and extending to the distal edge with the apex
Blake Inversion
Blake inversion refers to balancing the positive cast more than 10 degrees inverted. Additional modifications are performed to make the arch height tolerable. This technique is available only in plaster.
Inversion
A cast correction technique used to artificially increase the medial arch of the device, move the apex distally, and shift the center of the heel cup laterally. The positive cast
Lateral Heel Skive
The plantar lateral heel area of the positive cast is “flattened” to create a valgus wedge effect within the heel cup. This causes the center of the force that the
Medial Heel Skive
The plantar medial heel area of the positive cast is flattened to create a varus wedge effect within the heel cup. This causes the center of force that the orthosis
Cast Fill
Plaster added to the medial arch of the positive cast. The less cast fill that is added, the tighter the orthosis will conform to the arch of the foot. More
