Abstract: A fixation assembly for attaching a prosthetic leg and foot combination directly to an external ring fixation assembly via a protective socket, and yet allow full adjustment of length and offset, protection of the residual stump when in use, and quick-disconnect of the socket when not in use. The device is meant for use with any existing external fixation ring assembly for fixation to a femur or tibia, and any prosthetic leg/foot combination. The fixation assembly generally includes a molded concave socket having a mounting base at its apex for mounting the prosthetic leg/foot, an articulating ring adjustably attached to the socket, and a plurality of struts there between. Each strut has a first locking pivot joint at one end pivotally attached to the articulating ring and a second locking pivot joint at an opposing end pivotally attached to the rim of the socket. The articulating ring is removably attached to the external ring fixation assembly by a plurality of detent pins for releasable attachment.
