Abstract

The Dorsal Night Splint orthosis for human wearers includes a substantially rigid upright member consisting of an upper portion and a lower portion. When placed upon the foot of the wearer, said upper portion proceeds downward from approximately beneath the knee to the lower portion which terminates at the top of the foot. The lower portion is further defined by two opposed ankle splints. Said opposed ankle splints extend downward on each side of the ankle and wrap around, overlap and terminate at the Plantar aspect of the foot. A flexible member is positioned between the wearer and the upright member to provide padding for extended wearing of the device. The device is fastened to the wearer by one or more Velcro straps. When correctly placed upon the foot, the heel and the attachment of the Achilles tendon, as well as the wearer'"'"'s toes, remain exposed. This device is designed to be a supplemental form of treatment that, when worn at night or during extended periods of inactivity can, in conjunction with traditional treatment, significantly reduces the recovery time in the treatment of plantar fasciitis, acute ankle sprains, achilles tendon repair, foot drop, or any other condition or injury that would cause heel cord/Achilles tendon shortening in patients during periods of bed rest or when ankle immobilization is desired.

Claims

1. An anterior dorsal foot orthotic device, comprising:

an upper portion adapted to substantially engage only the anterior dorsal aspect of a patient'"'"'s lower leg during use, said upper portion having a rigid upright member adapted to extend vertically along the anterior dorsal aspect of the patient'"'"'s lower leg during use;

a lower portion adapted to extend from the upper portion horizontally along the patient'"'"'s foot during use, said lower portion defining two opposed ankle splints adapted to wrap around the medial and lateral aspects of the ankle of the wearer during use, said opposed ankle splints overlap each other and terminate under the plantar aspect of foot to define a split ortion to carry and support the foot during use;

a flexible member secured to and extending along an interior surface of both said upper and said lower portions;

an upper support strap removably attached to said upper portion to secure said upper portion to a wearer'"'"'s lower leg; and

a lower support strap removably attached to said lower portion to secure said lower portion around a wearer'"'"'s foot.

2. The anterior dorsal foot orthotic device of claim 1 wherein said upper support strap further comprises a first and a second upper support strap and a plurality of opposed slots through which said first and said second upper support strap extends.

3. The anterior dorsal foot orthotic device of claim 2 wherein said first and said second upper support straps are of a hook and loop type fastener.

4. The anterior dorsal foot orthotic device of claim 1 wherein said rigid upright member and said opposed ankle splints farther comprise a plurality of apertures.

5. The anterior dorsal foot orthotic device of claim 1 wherein said split base portion extends from slightly in advance of the heel of said wearer to before the toes of said wearer.

6. The anterior dorsal foot orthotic device of claim 1 wherein said opposed ankle splints are comprised of a substantially rigid material.

7. The anterior dorsal foot orthotic device of claim 1 wherein said rigid upright member extends from the dorsal portion of the foot to a point below the knee of said wearer.

8. The anterior dorsal foot orthotic device of claim 1 wherein said flexible member is comprised of a soft energy absorbing material.

9. An anterior dorsal foot orthotic device, comprising:

an upper portion and a lower portion, said upper portion extending vertically and said lower portion extending horizontally;

said upper portion having a rigid upright member, said rigid upright member placed substantially on the anterior portion of the wearer'"'"'s leg;

said lower portion forming opposed ankle splints;

a flexible member extending along an interior surface of said upper portion and said lower portion;

an upper support strap removably attached to said upper portion to secure said upper portion to a wearer'"'"'s leg;

a lower support strap removably attached to said lower portion to secure said lower portion around a wearer'"'"'s foot; and

,

wherein said opposed ankle splints overlap each other to form a split base portion which extends from slightly in advance of the heel of said wearer to before the toes of said wearer, said split base portio overlapping along the underside portion of the wearer'"'"'s foot.
