A thigh prosthesis or artificial leg comprising an upper socket portion designed to be secured, in use, to an amputee's stump, a lower leg portion, an articulation frame joining the socket portion to the leg portion, and resilient means for limiting and cushioning the articulation motion of the said articulation frame. The thigh prosthesis or artificial leg in accordance with the present invention lengthens during active deambulation phases and shortens during passive deambulation phases, thereby making it possible for the user to keep his center of gravity substantially at the same level during deambulation and to take advantage to a maximum extent of his instinctive sense of balance.
