Abstract
An orthopedic walking boot includes a housing configured to encompass at least a user's foot, a mechanically adjustable ramp insert including a ramp surface and disposed in the housing, an adjusting mechanism configured to adjust an elevation angle of the ramp surface, and a mechanically adjustable lift configured to cause the mechanically adjustable ramp insert to descend within the housing as the ramp surface is elevated such that vertical displacement of the user's foot caused by elevation of the ramp surface is substantially attenuated. Related methods are also provided.

An orthopedic walking boot, comprising:
- a housing configured to encompass at least a user's foot;
- a mechanically adjustable ramp insert comprising a ramp surface and disposed in the housing;
- an adjusting mechanism configured to adjust an elevation angle of the ramp surface;
- and
- a mechanically adjustable lift configured to cause the mechanically adjustable ramp insert to descend within the housing as the ramp surface is elevated such that vertical displacement of the user's foot caused by elevation of the ramp surface is substantially attenuated.
An orthopedic walking boot, comprising:
- a housing configured to encompass at least a user's foot;
- a mechanically adjustable ramp insert disposed in the housing, the mechanically adjustable ramp insert comprising:
- a ramp surface,
- a first support, and
- a second support, one or both of the first and second supports comprising a multi-ply leaf spring configured to attenuate a portion of physical loads transmitted to the user's foot when the user is walking;
- and
- an adjusting mechanism configured to adjust an elevation angle of the ramp surface.
A method for adjusting an orthopedic walking boot, comprising:
- adjusting an adjusting mechanism disposed on a housing of the orthopedic walking boot thereby achieving a desired elevation angle of a ramp surface of a mechanically adjustable ramp insert of the orthopedic walking boot;
- and
- inserting a user's foot into the housing and disposing the user's foot on the ramp surface such that the user's foot is supported in a position of plantarflexion determined at least in part by the desired elevation angle of the ramp surface,
- wherein adjusting the adjustment mechanism simultaneously causes a mechanically adjustable lift of the orthopedic walking boot to cause the mechanically adjustable ramp insert to descend within the housing as the ramp surface is elevated such that a vertical displacement of the user's foot caused by elevation of the ramp surface is substantially attenuated.
