Abstract: A method and device for making artificial limb sockets is disclosed. To form the socket, the patient's below the knee stump is covered with a pair of stockinettes and a balloon is invaginated thereover to form a smooth surface for producing a mold of the stump. A plaster mold is formed over the stump and removed before the plaster has totally hardened. A device comprising a caliper for measuring the dimension across the patient's adductor tubercle is applied to the mold before removal from the stump. After removal from the patient's stump the adductor tubercle dimension is reestablished using the caliper before the plaster hardens. The mold is employed to form a casting of the patient's stump and the accurate reproduction of the adductor tubercle dimension allows the formation of a satisfactory supracondylar suspension.
