Abstract

An orthopedic device includes a base shell having ankle and foot receiving portions. The base shell forms an opening over a dorsal aspect of the base shell. A dorsal shell is contoured to generally correspond to the opening in the base shell. The dorsal shell includes a proximal member connected to distal member via a flexible or resilient connecting portion arranged to accommodate a portion of a user's lower leg or ankle. A first flexible edge portion is attached to a distal terminal end of the distal member. The first flexible edge portion is arranged to bend or flex relative to the distal member so as to reduce the likelihood of pressure points on the user's toes from the distal member.

First claim

The invention claimed is:

1. An orthopedic device comprising:
a base shell having ankle and foot receiving portions, the base shell forming an opening over a dorsal aspect thereof;
a dorsal shell contoured to generally correspond to the opening of the base shell;
a compliance strap guide formed on an anterior aspect of the dorsal shell; and
a compliance assembly including a compliance strap extend through the compliance strap guide and around the posterior of the base shell such that the compliance strap is prevented from being slipped off of the orthopedic device and a compliance clasp attached to the compliance strap, the compliance clasp comprising;
a base member having a plurality of recesses formed therein;
a door member having a plurality of spike-shaped protrusions corresponding to the recesses, the door member pivotally connected to the base member and movable between an open position, wherein the door member is rotated away from the base member and the compliance strap is movable between the base and door members, and a closed position, wherein the door member is rotated toward the base member and the spike-shaped protrusions of the door member penetrate the recesses of the base member to lock or grasp the compliance strap between the base and door members; and
a detent system arranged to lock the door member in the closed position.

2. The orthopedic device of claim 1 , wherein the detent system includes one or more detents on the door member and one or more locking members on the based member corresponding to the one or more detents.

3. The orthopedic device of claim 2 , wherein the one or more detents are arranged to engage the one or more locking grooves when the door member is in the closed position.

4. The orthopedic device of claim 3 , wherein the one or more detents are irreversibly locked in the one or more locking grooves when the door member is in the closed position.

5. The orthopedic device of claim 3 , wherein the one or more detents and the one or more locking grooves are concealed within the compliance assembly when the door member is in the closed position.

6. The orthopedic device of claim 1 , further comprising a living hinge formed between the base member and the door member.

7. The orthopedic device of claim 1 , wherein the spike-shaped protrusions are formed of metal and the door member is formed of a plastic material.

8. The orthopedic device of claim 1 , wherein one or more of the spike-shaped protrusions are arranged to break when a tension is applied to the compliance strap with the door member in the closed position.

9. The orthopedic device of claim 1 , wherein the compliance strap is arranged to tear when a tension is applied to the compliance strap with the door member in the closed position.

10. An orthopedic device comprising:
a base shell having ankle and foot receiving portions, the base shell forming an opening over a dorsal aspect thereof;
a dorsal shell contoured to generally correspond to the opening of the base shell;
a first flexible edge portion attached to a proximal terminal end of the dorsal shell, the first flexible edge portion arranged to bend or flex when a leg of a user exerts a force on the first flexible edge portion so as to reduce the likelihood of pressure points on the leg;
a compliance strap guide formed on an anterior aspect of the dorsal shell; and
a compliance assembly including a compliance strap extend through the compliance strap guide and around the posterior of the base shell such that the compliance strap is prevented from being slipped off of the orthopedic device and a compliance clasp attached to the compliance strap, the compliance clasp comprising;
a base member having a plurality of recesses formed therein;
a door member having a plurality of spike-shaped protrusions corresponding to the recesses, the door member pivotally connected to the base member and movable between an open position, wherein the door member is rotated away from the base member and the compliance strap is movable between the base and door members, and a closed position, wherein the door member is rotated toward the base member and the spike-shaped protrusions of the door member penetrate the recesses of the base member to lock or grasp the compliance strap between the base and door members; and
a detent system arranged to lock the door member in the closed position.

11. The orthopedic device of claim 10 , further comprising a flexible toe portion attached to a distal terminal end of the dorsal shell, the flexible toe portion arranged to bend or flex when the user's toes exert a force on the flexible toe portion so as to reduce the likelihood of pressure points on the toes from the dorsal shell.

12. The orthopedic device of claim 10 , further comprising at least one observation hole formed in the base shell posterior to a user's malleoli when received in the base shell, the at least one observation arranged for tactile confirmation of the position of the foot within the orthopedic device.

13. The orthopedic device of claim 10 , wherein the spike-shaped protrusions extend at a right angle relative to the door member.

14. The orthopedic device of claim 10 , wherein the spike-shaped protrusions extend at an oblique angle relative to the door member.

15. The orthopedic device of claim 10 , wherein the spike-shaped protrusions are arrange to penetrate the recesses and lock a portion of the compliance strap within the compliance assembly when the door member is in the closed position.

16. The orthopedic device of claim 10 , wherein the spike-shaped protrusions are arranged to at least in part pierce the compliance strap when the door member is in the closed position.

17. An orthopedic device comprising:
a base shell having ankle and foot receiving portions, the base shell forming an opening over a dorsal aspect thereof;
a dorsal shell contoured to generally correspond to the opening of the base shell;
a compliance strap guide formed on an anterior aspect of the dorsal shell; and
a compliance assembly including a compliance strap extend through the compliance strap guide and around the posterior of the base shell such that the compliance strap is prevented from being slipped off of the orthopedic device and a compliance clasp attached to the compliance strap, the compliance clasp comprising;
a base member having a plurality of spike-shaped protrusions formed therein;
a door member having a plurality of recesses corresponding to the protrusions, the door member pivotally connected to the base member and movable between an open position, wherein the door member is rotated away from the base member and the compliance strap is movable between the base and door members, and a closed position, wherein the door member is rotated toward the base member and the spike-shaped protrusions of the base member penetrate the recesses of the door member to lock or grasp the compliance strap between the base and door members; and
a detent system arranged to lock the door member in the closed position.

18. The orthopedic device of claim 17 , further comprising a living hinge formed between the base member and the door member.

19. The orthopedic device of claim 17 , wherein the spike-shaped protrusions are arranged to penetrate the recesses and lock a portion of the compliance strap within the compliance assembly when the door member is in the closed position.

20. The orthopedic device of claim 17 , wherein one or more of the spike-shaped protrusions are arranged to break whe
