A preform for making a prosthetic limb socket includes an injection molded disk of thermoplastics material, and a peripheral portion of the disk is supported by a rigid metal ring. The ring and the peripheral disk portion have an interfitting connection which permits the disk and ring to be heated in an oven. The ring and softened disk are then inverted and stretched downwardly over a positive model of a residual limb while a vacuum is introduced through holes within the model to form a plastic socket which conforms to the model. The interfitting connection may be peripherally spaced studs on the ring and projecting into corresponding holes in the disk or may be an annular rib or arcuate rib sections on the ring which project into an annular recess or arcuate cavities within the disk. After the plastic cools, the ring is separated for reuse.

Slidable and rotatable coupler for a prosthetic leg

An adjustable connector assembly includes a circular one-piece base member adapted to be attached to a socket coupler for an amputee's residual limb. The base member has axially projecting spaced track portions which receive therebetween a circular flange of a slidable and rotatable one-piece connector member. A pair of clamping plates receive screws threaded into the track portions for releasably clamping the flange to the base member. In one embodiment, the connector member has a dome surface and a four sided boss projecting from the flange. In another embodiment, the connector member has a projecting annular collar having peripherally spaced threaded holes. The base member and connector member are adapted to be machined from solid titanium bar stock.
