ABSTRACT:
An external fixation assembly, and a method of treating fractures utilizing an external fixation assembly, are provided for facilitating the healing of fractured bones in a living body. Pins passing through bone portions are held stationary relative to each other by a frame which includes universal joints, articulation couplings, and adjustable length rods. Springs are provided in the assembly for applying compression to the universal joints allowing for the application of compression and the simultaneous application of axial loading to the bone portions. The universal joints and other components are arranged to provide free sliding of the components relative to each other upon loosening of the universal joints so that desired motion or force application at the fracture site may be provided.
