AD-prosthesis, IMFL-1, prosthesis for ankle disarticulation, including soft inner socket, exoskeletal


The prosthesis is composed by:
Functional components:
* ankle/foot device: SACH foot, eventually externally connected, or special foot, lightweight
Structural components:
* exoskeletal.
Interface component:
* soft inner socket.
Essential fitting through full contact and closed socket form at the tibia area. Reinforced dorsal and plantar motion at the upper part of the ankle joint. Pro- and supination control at the lower ankle joint through lateral control. Full contact between stump and socket.
Inner shank with distal opening, made from elastic or foam material (e.g. PE, EVA, leather-gummy). Outside shaft rigid construction and circularly closed, made from fibre material. Includes industrial functional foot component for level IMFL-1. Connection between inner and outside shank through closed form and friction.
Included are 2 test sockets and casting and cast preparation.
The integral prosthesis is custom made.

User Characteristics

Indications are for example:
* amputation of the heel part of the foot, more specifically a short heel stump excluding ankle joint (Syme amputation) in case a prefabricated component (foot/ankle) is possible
* amputation with a small lost of length of the leg in case a prefabricated component (foot/ankle) is possible.

Requires high stability of the prosthesis.
Sensitive of weight of prosthesis.

Level IMFL-1.

User Characteristics ICF Code

Contra Indication Text

Intended Use Text

Supposed to be used as functional (to sit and to transfer) and cosmetic replacement of the amputated part of the foot or leg for a user with the ability or potential to use the prosthesis for transfers, standing and very restricted ambulating on level surfaces at fixed cadence. Typical used for limited and unlimited household functioning.
Fits in a normal shoe.
Protect the stump against trauma, cold, pressure scores and false posture.
Motion control of the ankle joint.
Standing high load on stump through tibia fitting.
