Helix3D hip joint system
This newly developed prosthetic hip for hip amputees compensates for a large part of the missing muscles and reduces the amount of energy required when walking. With standard prostheses, patients have to lift their prosthetic leg high with their good side in order not to catch carpet edges or other obstacles. Helix3D enables a cushioned and controlled gait as well as a harmonious roll-over on the foot under full load. This is possible because the system, unlike standard prostheses, creates a three-dimensional movement.
The forces occurring in the prosthesis under oscillating motion must be reliably transferred without a noticeable increase in play. For this purpose, 4 bearings made of iglidur® Z were used on the two main axes. The prerequisite for using the iglidur® plain bearings included the high wear resistance.
