Ankle brace with ATF compression
First Claim
1. An ankle brace having a shell member, said shell member having a lateral elongated support member with a corresponding supporting cushion thereon and an opposed medial support member with a corresponding supporting cushion thereon, each of said supporting members and supporting cushions having a distal end and a proximal end, said support members being attached together at the distal ends thereof by a flexible web and having fastening means adapted to fasten the set of elongated support members about the leg with the supporting cushion placed between the elongated support member and the leg, and with the flexible web passing under the sole of the foot, the ankle brace further including:
- a cushioning element carried by one of the supporting cushions and comprising a flap extending outwardly from the distal anterior side of the lateral supporting cushion, said cushioning element having a shape sufficient to cover the area of the anterior talofibular ligaments;
a circumferential elastic strap passing between the lateral supporting cushion and the lateral support member and having sufficient length such that it extends over said cushioning element; and
hook-and-loop fasteners on said circumferential elastic strap such that said strap can attach to itself and provide compression to the flap to cause focal compression over the area of the anterior talofibular ligament and migration of the edemia upwardly from the distal area of the ankle to the proximal area of the ankle.

Abstract
A stirrup-type ankle brace having an outer shell member, the shell member having a lateral elongated, substantially rigid, support member with a corresponding supporting cushion thereon substantially coextensive therewith and an opposed medial support member with a corresponding cushion thereon. The lateral supporting cushion has a pre-inflated flap extending the anterior margin of its distal end with enough width to cover the area over and surrounding the anterior talofibular ligament. The flap is compressed against the ATF by a strap of elastic hook-and-loop compatible material. A tab of hook material is attached to the anterior end of the elastic strap so that it can engage the opposite end at any length. The strap is retained between the lateral shell and supporting cushion in the preferred embodiment so as to overlap the flap and compress the ATF ligament and medial malleolus when wrapped around the ankle. It does not wrap around either of the shells, but is at the outside surface of the lateral supporting cushion and the inside surface of the medial supporting cushion in the preferred embodiment.

7. An ankle brace comprising:
-
first and second spaced apart sidewall portions, each sidewall portion having a substantially rigid outer shell and a flexible support member substantially co-extensive with the outer shell for engaging the distal portion of the leg on each side thereof; a base portion having side regions attached to the first and second spaced apart sidewall portions such that the spaced apart sidewall portions extend upwardly therefrom; fastening means attached to at least one of the rigid outer shells for maintaining said flexible support member in engagement with corresponding confronting ankle portions; a flap extending from one of the flexible support members over the area of the anterior talofibular ligament; and a flexible strap passing between said one of the flexible support members and its corresponding substantially rigid outer shell and having a length sufficient to pass over said flap and apply a selectively variable pressure thereto. - View Dependent Claims (8)
