Hip Disarticulation Amputation Prostheses. The Canadian hip disarticulation prosthesis, introduced in the United States in 1954, is still used almost univers ly today. It consists of a foot, a shank, a prosthetic knee, a thigh, a hip joint/bumper/control strap, and a socket (Fig. 33.16). The hip disarticulation socket is essentially a bucket, providing a seat for the ischial tuberosity, medial-lateral stability, suspension, and support for weight bearing. 

The transtibial prosthesis incorporates one of the aforementioned prosthetic socket designs and suspension methods, a spacer (shank), and an artificial foot. The transfemoral prosthesis is similar, with the inclusion of a prosthetic knee unit and an additional spacer for the thigh. The spacer is usually made of wood, plastic, or metal depending on whether the design is exo- or endoskeletal.

Lower-limb-powered prostheses are another example of mobility robotic aids. In the past 30 years, the rapid advances in prosthetic technology resulted in a number of devices that improve the functional mobility and quality of life in individuals with lower-limb amputations [94]. Focusing on above-knee amputation, knee prosthesis design varies from the very simple single-axis knee to high-tech microprocessor-controlled prosthetic knees, such as the C-Leg from Ottobock [95]. One of the most important advancements in the...
