During the 1940s and 1950s, the most common type
of socket for the above-knee amputee in the United States was an
ischial containment socket (ischial tuberosity within the walls of
the socket) called a “plug fit” or “anatomical” socket. The
suspension method used for these prostheses was suspenders, pelvic
belt and band, or air chamber suction.
