Abstract

An orthopedic device includes a posterior shell with ankle and foot receiving portions. The foot receiving portion defines a plantar shell portion and side shell portions extending along first and second sides of the plantar shell portion and forming an open-ended toe portion. A toe protector portion is removably attached to the posterior shell at the open-ended toe portion and arranged to protect the toes of the user. The toe protector portion extends between the side shell portions and longitudinally along a length of the side shell portions. At least one inflatable bladder is disposed in at least the ankle receiving portions and at least one pump assembly is in fluid communication with the at least one inflatable bladder.

First claim

The invention claimed is:

1. An orthopedic device, comprising:
a posterior shell having ankle and foot receiving portions, the foot receiving portion defining a plantar shell portion and side shell portions extending along first and second sides of the plantar shell portion and forming an open-ended toe portion;
a toe protector portion attached to the posterior shell at the open-ended toe portion and arranged to protect toes of a user when the orthopedic device is worn, the toe protector portion extending between the side shell portions and longitudinally along a length of the side shell portions;
a dorsal shell contoured to substantially correspond to an opening of the posterior shell, the dorsal shell defining a reinforcing ridge positioned centrally and extending longitudinally along and from an exterior surface of the dorsal shell;
wherein the dorsal shell includes a proximal member and a distal member hingedly connected to the proximal member by a connecting portion, the reinforcing ridge being aligned across the proximal and distal members and the connecting portion, the connecting portion being more flexible than the proximal and distal members.

2. The orthopedic device of claim 1 , further comprising a plurality of clearance holes defined in the dorsal shell.

3. The orthopedic device of claim 2 , wherein at least some of the clearance holes extend at an oblique angle relative to the reinforcing ridge.

4. The orthopedic device of claim 2 , further comprising a second plurality of clearance holes defined in the ankle receiving portion of the posterior shell.

5. The orthopedic device of claim 1 , further comprising a D-ring pivotally attached to at least one of the side shell portions.

6. The orthopedic device of claim 5 , further comprising a strap member extending through the D-ring and between the side shell portions.

7. The orthopedic device of claim 1 , wherein the posterior shell has first and second wing portions forming an opening over a dorsal aspect thereof.

8. The orthopedic device of claim 1 , wherein the posterior shell includes a proximal edge having a flexible configuration.

9. The orthopedic device of claim 1 , wherein the posterior shell defines a first plurality of clearance holes extending in a first direction, and a second plurality of clearance holes extending in a second direction different than the first direction.

10. The orthopedic device of claim 1 , further comprising a strap secured to the posterior shell, and arranged to extend over the connecting portion of the dorsal shell.

11. The orthopedic device of claim 1 , wherein the connecting portion defines a gap formed along one surface thereof generally perpendicular to the reinforcing ridge.

12. An orthopedic device, comprising:
a posterior shell having side shell portions defining ankle and foot receiving portions, and first and second wing portions forming an opening over a dorsal aspect thereof;
an outsole having a toe protector portion extending upwardly and attached to the posterior shell at an open-ended toe portion of the foot receiving portion and arranged to protect toes of a user when the orthopedic device is worn, the toe protector portion extending between the side shell portions and longitudinally along a length of the side shell portions, the outsole including a heel protector and a plurality of cushioning structures located between the toe protector portion and the heel protector;
a dorsal shell contoured to substantially correspond to the opening of the posterior shell, the dorsal shell including a proximal member and a distal member hingedly connected to the proximal member via a connecting portion more flexible than the proximal and distal members;
a reinforcing ridge extending longitudinally along an exterior surface of the dorsal shell across both of the proximal and distal members and the connecting portion.
