ABSTRACT:
An apparatus for connecting a prosthesis to a bone of a stump of an amputated limb such as the arm or leg of a person. The apparatus includes a tubular female socket adapted to be inserted within an intermedullary cavity of the bone. The tubular socket has an open lower end with a sleeve of bio-compatible material permitting access through the skin of the amputee's stump. The prosthesis has a contoured support for receiving the stump of the amputee. A quick disconnecting lock pin is carried adjacent the center of the contoured support. The lock pin is adapted to be received within the female socket for securing the prosthesis to the tubular female socket carried within the bone. The mounting for the lock pin is adjustable so that the degree of support provided through the bone as compared to the degree of support provided through the flesh of the stump engaging the wall of the prosthesis can be varied.
