What defines a transfemoral prosthesis?

A transfemoral prosthesis specifically refers to an artificial limb designed for individuals who have undergone an amputation above the knee. This type of prosthesis replaces the portion of the leg that includes the femur and is tailored to provide support and mobility to the individual. It typically includes a socket that fits over the residual limb and connects to a knee joint and foot, allowing for a range of motion similar to that of a natural leg.

The other options do not align with the definition of a transfemoral prosthesis. An artificial limb below the knee refers to a transtibial prosthesis, which is used for amputations below the knee. An artificial limb for partial foot replacement is intended for individuals who have had partial foot amputations and does not involve the knee joint at all. An orthosis for spinal support, on the other hand, refers to a device designed to provide support or immobilization for the spine and is not classified as a prosthetic limb for lower extremities.
