How Modern Prosthetics Work

The Suspension System

The attachment mechanism, known as the suspension system, is an essential part of a well-fitting prosthetic limb. The suspension system can consist of a suction socket, an elastic sleeve, or an old-fashioned arrangement of harnesses and straps. The fitting must be secure and snug, not only because it is vital for comfort, but because it ensures the prosthetic limb can be controlled properly. In many cases, the socket is a part of the suspension system arrangement. In the instance of a prosthetic leg, sockets may come in the form of a large plastic casing that is hollow so the residual limb can be inserted.
