Abstract
An external fixation system includes top and bottom fixation plates that may be connected to fragments of a bone. At least one y-shaped strut attaches the two fixation plates. Each y-shaped strut has first, second and third telescopic struts coupled at a connector joint. The first strut member is coupled to the top fixation plate and the second and third strut members are coupled to the bottom fixation plate. Each strut member may include a joint and may also include an actuation unit connecting the particular strut member to the top or bottom fixation plate. Rotation of a head portion of the actuation unit causes rotation of a threaded rod, causing adjustment in the length of the respective strut member. As the lengths of the strut members change, the joints may reposition, leading to the top fixation plate becoming repositioned with respect to the bottom fixation plate.
