Abstract

Abstract The invention relates to a foot splint for correcting abnormalities and foot deformations that are sometimes found in newborn and yound children. It includes relatively fixed, angularly related foot supports, each having a wall about the heel and extending continuously along a length of each support to apply a medial restraint and lateral support to the inner surface of the foot and heel while strap means retains each foot on its respective support to prevent displacement of the heel as well as medial displacement of the forefoot relative to its respective support.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 250 words
A foot splint for attachment to the feet of a child for correcting toe-in and related abnormalities comprising a substantially planar support for the full length of each foot, a heel support unitary with each of said foot supports, said heel supports extending for a portion of the length of its respective foot support at a medial inner portion thereof and being curved about the heel of its respective foot support for a portion thereof delineating the heel of its respective foot support, a wall contiguous with each planar support to extend upward therefrom beginning from the forefoot supporting portion of said planar support and continuing rearward therealong toward and as a contiguous extension of said heel support, means rigidly connecting said foot supports against relative movement, each said heel support including means extending upward from its respective foot support for a height sufficient to apply a restraint to and against the relative movement of the heel of a foot positioned thereagainst while permitting rotation of the foot at the heel so restrained, each foot support being disposed at an eversion angle wherein the inside of each foot support is lowered relative to the outside thereof, and strap means on each of said foot supports to engage the forefoot of a foot positioned on a respective foot support to inhibit the medial rotation of the forefoot relative to its respective foot support and applying a lateral outward force thereto to rotate the foot about the restrained heel of the foot.
Claim 2
Dependent Claim 250 words
A foot splint for attachment to the feet of a child for correcting toe-in and related abnormalities comprising a substantially planar support for the full length of each foot, a heel support unitary with each of said foot supports, said heel supports extending for a portion of the length of its respective foot support at a medial inner portion thereof and being curved about the heel of its respective foot support for a portion thereof delineating the heel of its respective foot support, a wall contiguous with each planar support to extend upward therefrom beginning from the forefoot supporting portion of said planar support and continuing rearward therealong toward and as a contiguous extension of said heel support, means rigidly connecting said foot supports against relative movement, each said heel support including means extending upward from its respective foot support for a height sufficient to apply a restraint to and against the relative movement of the heel of a foot positioned thereagainst while permitting rotation of the foot at the heel so restrained, each foot support being disposed at an eversion angle wherein the inside of each foot support is lowered relative to the outside thereof, and strap means on each of said foot supports to engage the forefoot of a foot positioned on a respective foot support to inhibit the medial rotation of the forefoot relative to its respective foot support and applying a lateral outward force thereto to rotate the foot about the restrained heel of the foot.
Claim 3
Dependent Claim 39 words
A foot splint as in claim 1, said connecting means including means operable to release each of said foot supports from their connected fixed diverging angular relation and to connect the same together in said fixed diverging angular relation.
Claim 4
Dependent Claim 42 words
A foot splint as in claim 2, said foot supports being greater in length and lesser in width than that of a foot to be positioned thereon to enable said instep strap means to apply its lateral outward force to the foot.
Claim 5
Dependent Claim 37 words
A foot splint as in claim 1, each of said foot supports being tilted downward to conform to the natural carrying angle of a foot positioned on said foot supports and with respect to the leg thereof.
