Abstract
Abstract The present invention is directed to a foot splint for the correction of toed-in or pigeon-toeing, sometimes known as clubfoot, by the use of a single fixed angle support for both feet simultaneously without the requirement for dynamic periodic readjustment.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
132 words
A corrective foot splint comprising a single unitary, open unincumbered base, said base having a heel support thereon intermediate the ends thereof, said heel support having two heel support surfaces at field angles relative to each other, said base having foot supports being substantially planar surfaces open and free of limiting operative structures and with one of said supports for each of said heel support surfaces and extending in liee with each of their respective heel support surfaces to support a foot, the heel of which is adapted to be positioned against the respective one of said heel support surfaces, and releasable means on said base to retain a foot on each of said foot supports and to prevent the removal of the heel of the foot from its respective heel support.
Claim 2
Dependent Claim
132 words
A corrective foot splint comprising a single unitary, open unincumbered base, said base having a heel support thereon intermediate the ends thereof, said heel support having two heel support surfaces at field angles relative to each other, said base having foot supports being substantially planar surfaces open and free of limiting operative structures and with one of said supports for each of said heel support surfaces and extending in liee with each of their respective heel support surfaces to support a foot, the heel of which is adapted to be positioned against the respective one of said heel support surfaces, and releasable means on said base to retain a foot on each of said foot supports and to prevent the removal of the heel of the foot from its respective heel support.
Claim 3
Dependent Claim
30 words
A corrective foot splint as in claim 1, each one of said respective foot and heel supports diverging from and relative to the other at an angle of approximately 60*.
Claim 4
Dependent Claim
73 words
A corrective splint comprising a pair of open, substantially unobstructed, foot supporting surfaces diverging at fixed angles relative to each other, each of said foot supporting surfaces being connected to each other at their heels in spaced relationships to form a unitary structure incapable of relative movement, a heel shaped support defined at the heel of each of said foot supporting surfaces, and releasable means on each of said open foot supporting surfaces.
Claim 5
Dependent Claim
73 words
A corrective splint comprising a pair of open, substantially unobstructed, foot supporting surfaces diverging at fixed angles relative to each other, each of said foot supporting surfaces being connected to each other at their heels in spaced relationships to form a unitary structure incapable of relative movement, a heel shaped support defined at the heel of each of said foot supporting surfaces, and releasable means on each of said open foot supporting surfaces.
Claim 6
Dependent Claim
13 words
A corrective splint as in claim 3, said diverging angle being approximately 60*.
Claim 7
Dependent Claim
34 words
A corrective splint as in claim 3, each of said foot supporting surfaces being substantially planr, said heel shaped supports each being connected together and being raised above said substantially planar foot supporting surfaces.
Claim 8
Dependent Claim
25 words
A corrective splint as in claim 3, said heel shaped supports being defined in the connection of said foot supporting surfaces and being unitary therewith.
