Traditional prosthetic sockets are almost circular in cross section. This shape permits the remaining bone to move substantially before it is close enough to the socket wall to cause motion. Compression-stabilized sockets are made with four long depressions that push the tissue close to the bone and prevent motion. Between these depressions are open release areas to accommodate the displaced tissue. The release areas may be left open for cooling. Persons with above-knee amputations have improved gait and stability, while persons with arm amputations have better control of their artificial hands or hooks.
