Abstract: Prosthetic apparatus includes a pyramid adaptor and a pylon connected together by an outer sleeve, which may be an elastomeric element. The sleeve or element is clamped to both the pyramid adaptor and to the pylon to provide shock absorbing characteristics and to allow relative axial rotation between the pyramid adaptor and the pylon. Different configurations or embodiments of sleeves are illustrated, and the use of a third clamp is also illustrated.

Abstract: Prosthetic foot apparatus includes a flexible foot plate, an elastomeric block, and a tubular pylon element. The tubular pylon element includes an upper tubular portion, a partially flattened curved portion, and a generally flattened lower portion secured to the foot plate by an elastomeric block. The elastomeric block is configured to allow, with the pylon and the foot plate, inversion, eversion, dorsi flexion, and planar flexion movements of the apparatus to simulate ankle and toe movements of a normal foot. The foot plate and the tublar pylon allow for dorsi flexion and planar flexion movements, and the elastomeric block is appropriately configured to add inversion and eversion movements as well as dorsi flexion and planar flexion movements of the apparatus.
