An article including a spinal prosthesis having a unitary body with at least three attachment points attachable to spinal structure, the unitary body including a flexure assembly positioned between first and second attachment members, wherein flexure of the flexure assembly permits movement of the first attachment member relative to the second attachment member.

Certain embodiments of the invention relate to increasing the functionality of a transfemoral prosthetic device. In one embodiment, the transfemoral prosthetic device is configured such that the prosthetic knee maintains a load consistent with a healthy knee walking on level ground, while the prosthetic ankle adjusts for the incline or decline. In certain embodiments, adjustments, such as a toe lift function, are automatically performed after about three strides of the transfemoral prosthetic device user and / or when each of the strides has a stride speed of at least about 0.55 meters / second.

Prosthetic joints, components for prosthetic joints, superhard bearing and articulation surfaces, diamond bearing and articulation surfaces, substrate surface topographical features, materials for making joints, bearing and articulation surfaces, and methods for manufacturing and finishing the same, and related information are disclosed, including prosthetic knee joint having at least one diamond articulation surface.

A simple, inexpensive prosthetic foot is provided incorporating a cushioned ankle including an ankle block formed of a resilient material or bladder having desired compliance and energy return characteristics. The ankle block is sandwiched between a foot element and an ankle element. One or more openings extends through the ankle block with a substantially transverse orientation relative to a forward walking motion. The size and shape of these openings, as well as the insertion of different types of stiffeners therein, provide desired performance characteristics to the ankle block. When the ankle block takes the form of one or more inflatable bladders, the pressure within these bladders is individually controlled by valves to provide desired performance characteristics to different portions of the prosthetic foot. A pump system can also be used to control and generate fluid pressure into these bladders. A preferred pump system generates fluid pressure based upon the movement of the amputee onto two telescoping pylons that are connected to the prosthetic foot.
