  • Publication number: 20240358537
    Abstract: An orthotic device for a medical boot includes a first arm for attachment to a first portion of the medical boot, and a second arm for attachment to a second portion of the medical boot. A hinge assembly adjustably fixes an angle between the first and second arms. The hinge assembly includes a first hinge component attached to the first arm, a second hinge component attached to the second arm, and an actuator extending from a proximal end toward a distal end. The distal end of the actuator is biased by a force from a biasing member into a locked position preventing the first and second hinge components from rotating relative to one another. The proximal end of the actuator when actuated, displaces the actuator from the locked position into an unlocked position allowing the second hinge component to rotate relative to the first hinge component.
