The VPS System is an innovative, sub-ischial prosthesis socket that offers people maximum comfort and mobility following an upper-leg amputation. It makes such effective use of the inactive zones between the remaining muscle groups that the VPS System is suitable even for users with low mobility. As osseous side or base support points are no longer required, pressure areas are a thing of the past and even the sensitive hygiene area remains free. All everyday movements can be performed without restrictions - even cycling is no problem.
