AD-prosthesis, IMFL-4, prosthesis for ankle disarticulation, including soft inner socket and multi-purpose foot, exoskeletal


The prosthesis is composed by:
Functional components:
* ankle/foot device: energy storing foot or multi axial ankle/foot with dynamic response or Flex walking system or equal
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 ankle joint. Pro- and supination control at the lower ankle joint through lateral control. Full contact between socket and stump.
Inner shank with distal opening, made from elastic or foam material (e.g. PE, EVA, leather-gummy). Outer shank rigid construction and circularly closed, made from fibre material. Includes industrial functional foot component for level IMFL-4. Connection between inner and outside shaft through closed form and friction.
Included are 2 test sockets and casting and cast preparation.
The integral prosthesis is custom made.
