More than 2 million people in the United States are living with limb loss or limb differences, a number expected to double by 2050 due to vascular disease and diabetes. But statistics don’t capture the reality—the sound of a carbon fiber foot hitting pavement, the smell of a new silicone liner, or the quiet triumph of buttoning a shirt with one hand.

The interface between the human body and the machine is the socket. If it doesn't fit perfectly, you will get blisters, skin breakdown, or simply refuse to wear it. A good prosthetist (the clinician who makes the device) is worth their weight in gold.

There is a moment, often just after the initial shock of surgery or accident, when an amputee looks down and sees a new geography to their body. That moment is rarely easy. It can be filled with grief, phantom pain, and the daunting question: Who am I now?

If you ask an amputee what hurts the most, they won't point to the scar. They will point to the space where their foot used to be.

Never touch someone’s prosthetic leg without asking. That leg is a part of their body space. Grabbing it is like grabbing their thigh.
