Abstract

A hinged orthopedic knee brace has a structural frame made up of a plurality of rigid or stiffened support components dynamically connected by one or more hinges. A plurality of pneumatic pads are attached to the inside faces of the frame to effectively grip the body of the user and simultaneously cushion the body from the frame. Each pad is connected in selective fluid communication with a pump and a fluid release valve enabling the user to instantaneously inflate or deflate the pads whenever desired to enhance the fit of the brace on the body of the user.

Claims

1. An orthopedic brace positionable on a body of a user about a joint comprising:

a substantially rigid or stiffened upper support component having an inside face positionable proximal to the body of the user above the joint;

a substantially rigid or stiffened lower support component having an inside face positionable proximal to the body of the user below the joint;

a hinge rotatably connecting said upper and lower support components having a substantially rigid or stiffened inside face positionable proximal to the body of the user at the joint;

a pad having a bladder, said pad engaging said inside face of said hinge and positionable against the body of the user at the joint, wherein said bladder has a loop substantially encircling an interior opening, said loop adaptable in size to substantially circumscribe a condyle of the joint and said interior opening adaptable in size to receive a bony protrusion of the condyle, thereby alleviating pressure applied to the bony protrusion by said hinge plate; and

a pump in fluid communication with said bladder adapted for addition of a fluid to said bladder.

2. An orthopedic brace as recited in claim 1, wherein said loop is a closed curve.

3. An orthopedic brace as recited in claim 2, wherein said loop is a partially opened curve.

4. An orthopedic brace as recited in claim 1, further comprising a fluid release valve in fluid communication with said bladder having an open position and a closed position adapted for release of fluid from said bladder.

5. An orthopedic brace as recited in claim 1, further comprising means for selectively providing fluid communication from said pump to said bladder and preventing fluid communication from said bladder to said pump.
