ABSTRACT:
An endoskeletal system having an adjustable adapter assembly is disclosed. In one embodiment the adapter assembly utilizes a ball-and-post coupler to adjustably couple an endoskeletal pylon to a stump socket or artificial foot or hand. The adapter assembly includes a cylindrical collar which is fastened to one end of the pylon. The interior bore of the collar is spherically contoured to form a seat for receiving a bulbous end of the ball-and-post coupler, which itself is fastened to the stump socket via a socket adapter plate. The spherical interface of the ball-and-post coupler and the seat forms a articulable bearing.
