Abstract: An interface fitting module (10) for fitting the interface portion of an ischial containment socket for an above-knee amputee. The module (10) has a sleeve-like body portion (11) with proximal and distal ends (12 and 13), respectively. At least the proximal end (12) of the body portion (11) is open to receive the residual thigh (15) of an above-knee amputee. Means in the nature of a lap joint (25) are provided selectively to adjust the peripheral dimension of said body portion (11) so that it will circumscribe, and engage, the peripheral thigh (15) to the desired degree. The body portion (11) of the module (10) is sufficiently transparent to permit visual observation as to the conformity between the body portion (1) of the module (10) and the residual thigh (15) received therein.

Abstract: An ischial containment socket (10) having a frame (12) that is separate from, and is capable of being selectively secured to, an interface (11). The interface (11) has proximal and distal ends (14 and 15)and at least the proximal end (14) is open to receive the residual limb of an above-knee amputation. The interface (11) has four walls (16, 18, 19 and 20), and the dimension between the medial and lateral walls (18 and 19) is less than the dimension between the posterior and the anterior walls (16 and 20). The proximal ends of the adjacent posterior and medial walls (16 and 18) present a containment brim (30). The brim (30) is in the form of a flared offset wall (31) that extends generally outwardly and upwardly from the proximal ends of the adjacent posterior and medial walls (16 and 18). A reversely curved containment recess (32) is provided in the flared offset wall ( 31).
