Prof. Pistorius is a symes amputee. Her residual limb is extremely atrophied; therefore, she has a very thin and bony stump as one can clearly see (photo 2). In order to assist Prof. Pistorius, we used modern technology to manufacture a custom silicone liner (photo 1) to provide her leg with better comfort and suspension. We sent a cast of her leg to another company so that they could make the silicone liner. Once we had the silicone liner, we were able to manufacture the prosthesis (photo 3). We conducted an eight week trial period where the patient walked with a test socket. During this period we extensively "fine-tuned" the prosthesis as the fit of the socket had to be very accurate to be comfortable in order to compensate for all the bony prominences.
