Abstract

An exoskeletal orthosis includes a proximal cuff including a hinge along an upper edge of the cuff; an ankle section/footplate; and at least one posterior strut connecting the proximal cuff to the ankle section and foot plate.

First claim

What is claimed is:

1. An orthosis, comprising:
a two piece proximal cuff having an upper edge and a lower edge;
an ankle section/footplate comprising an ankle section and a footplate section;
dual straight posterior struts attached at a rear of the proximal cuff and attached at a rear of the ankle section/footplate; and
at least one hinge along the upper edge of the proximal cuff, the at least one hinge being configured to allow a bottom of a front piece of the lower edge to move outward and upward from a bottom of a rear piece of the lower edge.

2. The orthosis of claim 1 , wherein the dual straight posterior struts comprise carbon.

3. The orthosis of claim 1 , wherein the dual straight posterior struts comprise a reinforced carbon fiber composition.

4. The orthosis of claim 1 , further comprising two mounting plates for the dual straight posterior struts.

5. The orthosis of claim 1 , wherein the footplate section has a rollover shape.

6. The orthosis of claim 1 , wherein a heel of the ankle section/footplate includes a cushion.

7. The orthosis of claim 1 , wherein the two piece proximal cuff includes a strap.

8. The orthosis of claim 1 , wherein the ankle section comprises a lateral wing for mediolateral stability.

9. The orthosis of claim 1 , wherein the ankle section and footplate section comprise a single piece comprising a reinforced carbon composition.

10. The orthosis of claim 1 , wherein the footplate section has an arch.

11. The orthosis of claim 1 , wherein a forefoot section of the footplate section is in plantarflexion compared to a midfoot section.

12. The orthosis of claim 1 , wherein the dual straight posterior struts each have a tubular shape and have a length of about 5 inches to about 13 inches.

13. The orthosis of claim 1 , further comprising a cushioned foam attached to a proximal sole on a bottom portion of the ankle section, wherein a thickness and density of the foam are specific to an ankle injury.

14. The orthosis of claim 1 , wherein the at least one hinge is configured to provide a wider opening at the lower edge when donning the orthosis than when the orthosis is in use.

15. The orthosis of claim 1 , wherein the dual straight posterior struts are parallel.

16. An orthosis, comprising:
a two piece cuff having an upper edge and a lower edge;
at least one hinge along the upper edge of said cuff;
an ankle section/footplate comprising an ankle section and a footplate section; and
parallel dual posterior struts attached at a rear of the cuff and attached at a rear of the ankle section/footplate,
wherein said at least one hinge is a fixed axis point that is configured to allow a front section of the lower edge to be openable upwards from a fixed rear section of the lower edge.

17. The orthosis of claim 16 , wherein the cuff includes a strap.
