Page Fields

Y-Rib

A Y-Rib is a modification applied to the plantar surface of a 3D Printed orthosis. This modification adds thickness in a Y pattern that provides increased thickness on the surface inferior to the talonavicular joint (TNJ), calcaneocuboid joint (CCJ) and midpoint of the 1st metatarsal.

This modification is intended to increase the longitudinal and torsional stiffness of a 3D Printed orthosis and is commonly used with thinner overall Shell Thickness requests to facilitate a lighter product with stiffness in more failure prone areas.

Default Value	Minimum Value	Maximum Value
0mm	0mm	2mm

K-Rib

A K-Rib is a modification applied to the plantar surface of a 3D Printed orthosis. This modification adds thickness in a K pattern that provides increased thickness on the surface inferior to the talonavicular joint (TNJ), lateral longitudinal arch (LLA) and midpoint of the 1st metatarsal.

This modification is intended to increase the longitudinal and torsional stiffness of a 3D Printed orthosis and is commonly used with thinner overall Shell Thickness requests to facilitate a lighter product with stiffness in more failure prone areas.

Default Value	Minimum Value	Maximum Value
0mm	0mm	2mm

Cuboid Plantar Modifier

A Cuboid Plantar Modifier is a modification applied to the plantar surface of a 3D Printed orthosis. This modification adds thickness on the surface inferior to the cuboid.

This modification is intended to increase the longitudinal stiffness of the lateral longitudinal arch (LLA).

Default Value	Minimum Value	Maximum Value
0mm	0mm	2mm

Styloid Plantar Modifier

A Styloid Plantar Modifier is a modification applied to the plantar surface of a 3D Printed orthosis. This modification adds thickness on the surface inferior to the styloid process.

This modification is intended to increase the longitudinal stiffness of the lateral longitudinal arch (LLA).

Default Value	Minimum Value	Maximum Value
0mm	0mm	2mm

Navicular Plantar Modifier

A Navicular Plantar Modifier is a modification applied to the plantar surface of a 3D Printed orthosis. This modification adds thickness on the surface inferior to the talonavicular joint (TNJ).

This modification is intended to increase the longitudinal stiffness of the medial longitudinal arch (LLA).

Default Value	Minimum Value	Maximum Value
0mm	0mm	2mm

1st Ray Plantar Modifier

A 1st Ray Plantar Modifier is a modification applied to the plantar surface of a 3D Printed orthosis. This modification adds or removes thickness on the surface inferior to the 1st metatarsal.

This modification is intended to increase or decrease the longitudinal stiffness of the medial longitudinal arch (MLA). A negative value is intended to result in less ground reaction force resisting the plantarflexion of the 1st metatarsal joint. This is intended to allow for a more efficient windlass function during the gait cycle.

Default Value	Minimum Value	Maximum Value
0mm	-1mm	2mm

5th Ray Plantar Modifier

A 5th Ray Plantar Modifier is a modification applied to the plantar surface of a 3D Printed orthosis. This modification adds or removes thickness on the surface inferior to the 5th metatarsal.

A negative value in this field is not recommended when using semi-weight bearing or weight-bearing scan formats, as this will result in a lateral arch that is of low thickness and prone to failure.

Default Value	Minimum Value	Maximum Value
0mm	-1mm	2mm
