Abstract: A multi-axis prosthetic ankle having an adjustable range of articulation and a method of adjusting the range of articulation of such an ankle. A lower leg connection component extends from the receiving cavity of a prosthetic foot connection component. The remainder of the receiving cavity is substantially filled with an elastomeric material. An interchangeable external bearing resides atop a portion of the elastomeric material and includes an aperture through which a portion of the lower leg connection component passes. By exchanging an installed external bearing for an external bearing having an aperture of different size, the limits of movement of the lower leg connection component can be altered and the overall range of articulation of the ankle adjusted.

Abstract: A multi-axis prosthetic ankle for connection of a prosthetic lower leg to a prosthetic foot. A substantially hollow prosthetic foot connection component includes a receiving cavity for receiving a portion of a lower leg connection component. A retainer or retainer assembly is preferably installed into the receiving cavity to help retain the lower leg connection component therein. Once the necessary components are in place, the remainder of the receiving cavity is substantially filled with an elastomeric material. An external bearing may reside atop the elastomeric material and act in conjunction with the elastomeric material to control ankle flexion.
