Abstract

An ankle and foot therapeutic device for use in supporting a patient'"'"'s foot and leg and selectively immobilizing the patient'"'"'s ankle. The brace is of a multiple part configuration having a heel portion, leg portion and foot portion. The leg portion and foot portion being interconnected by a range of motion assembly. The range of motion assembly having a pivot point for adjustable plantar and dorsi flexion by the patient'"'"'s foot. The heel portion having a configuration to provide a space with the patient'"'"'s heel.

Claims

1. A therapeutic ankle and foot device for a patient, the device comprising:

a leg portion, a foot portion and a heel portion, said foot portion being at an angle to said leg portion;

an interconnecting range of motion assembly being integral with one end of said leg portion, said interconnecting range of motion assembly having an upper ankle support member and a lower ankle support member, said upper and lower ankle support members being pivotally connected to one another at a pivot point being lateral to a patient'"'"'s ankle during use, said ankle support member being integral with and extending upwardly and diagonally from said heel portion, said range of motion assembly having an apertured motion plate with an adjustable stop attached thereto for selective engagement between said lower ankle support member and said upper ankle support member, said apertured motion plate having an arcuate aperture; and

said heel portion having a configuration to provide a space between the patient'"'"'s heel and said heel portion to prevent the application of pressure to the patient'"'"'s heel, and said heel portion being attached to said foot portion wherein the pivot is inwardly from said heel portion and substantially lateral to the patient'"'"'s ankle during use such that the range of dorsi and plantar flexion between said leg portion and foot portion may be freely adjusted with the interconnecting range of motion assembly.

2. The therapeutic ankle and foot device as set forth in claim 1, wherein said interconnecting range of motion assembly has a return spring to resiliently engage the upper ankle support member and the lower ankle support member.

3. The therapeutic ankle and foot device as set forth in claim 1, wherein said lower ankle support member is connected to an end of the heel portion adjacent to said foot portion.

4. The therapeutic ankle and foot device as set forth in claim 1, wherein said upper and lower ankle support members are pivotally connected to one another at two pivot points, each pivot point being on opposite sides of and lateral to the patient'"'"'s ankle during use.

5. The therapeutic ankle and foot device as set forth in claim 1, wherein said adjustable stop attached to said apertured motion plate comprises an engagement pin.

6. A therapeutic ankle and foot device for a patient, the device comprising:

a leg portion, a foot portion, a heel portion and range of motion assembly, said foot portion being at adjustable angles to said leg portion;

said range of motion assembly having an upper ankle support member and a lower ankle support member, said upper and lower ankle support members being interconnected to one another at a pivot point, said lower ankle support member being integral with and extending upwardly and diagonally from said heel portion, said range of motion assembly having an apertured motion plate with an adjustable stop extending therefrom for selective engagement, said apertured motion plate having an arcuate aperture and said range of motion assembly further comprising a spring element between said upper and lower ankle support members imparting dorsi flexion force to said foot portion; and

said heel portion being curved and extending from said foot portion to provide a space between a patient'"'"'s heel and said heel portion wherein the pivot point is inwardly from said heel portion and substantially lateral to the patient'"'"'s ankle during use such that the range of dorsi and plantar flexion between said leg portion and said foot portion may be freely adjusted with said range of motion assembly.

7. The therapeutic ankle and foot device as set forth in claim 6, wherein said lower ankle support member is secured to said heel portion adjacent to said foot portion.

8. The therapeutic ankle and foot device as set forth in claim 6, wherein said upper ankle support member is secured to said leg portion in spaced relation to said heel portion.

9. The therapeutic ankle and foot device as set forth in claim 6, wherein said adjustable stop attached to said motion plate comprises an engagement pin.

10. The therapeutic ankle and foot device as set forth in claim 6, wherein said adjustable stop selectively engages said upper ankle support member, the adjustable stop comprising a selectively positionable engagement pin attached to said range of motion plate.
