What is a socket?
A socket is the portion of prosthesis that fits around the amputated or residual limb (commonly called a “stump”). Prosthetic components are attached to the socket. There are many ways to make a socket including using materials such as wood, polyester resin, acrylic, and thermoplastics. Each of those methods and materials has its own benefits and detractors. For example, a socket carved from a piece of wood is inexpensive but very heavy and usually poor fitting. A thermoplastic socket can be made quickly and for relatively low costs, but requires specialty equipment such as an oven. Thermoplastics are also not as strong and long lasting.
