Abstract: This patent is basically an Engineering design of a means to vary the length of a rod of two parts that are coupled together by an electrically operated motorized turnbuckle which can be activated remotely when it is difficult or impossible to access directly. This is accomplished by holding a wand that induces positive or negative pulses to the electrically operated motorized turnbuckle according to the direction of rotation desired for the electrically operated motorized turnbuckle to turn.

Abstract: The currently used method for the replacement of joints greatly limits how the joint can be used. This invention overcomes these limitations returning the joint to full normal use. This is accomplished by my development of a system of joints that stay intact up to just short of bone breaking. At this point it will pop out. It can then be reset simularly to resetting a normal joint. This invention also includes a system for total limb replacement including limited action joints. Also included are various clamps to assist the surgeon.
