Abstract
A dynamic strut for external fixation constructs has first and second sub-struts that are axially adjustable in length and rotational position relative to one another, with the first sub-strut supporting a first dual universal joint with a first attachment peg for connection to an external fixator, and the second sub-strut supporting a second dual universal joint with a second attachment peg for connection to an external fixator. The first and second dual universal joints each include first and second ball-and-socket joints, whereby the associated attachment peg is adjustable in orientation. Set screws fix orientation of the attachment peg relative to the first ball-and-socket joint and the housing. Angular orientation of the first dual universal joint is fixed while angular orientation of the second dual universal joint is adjustable. The second sub-strut supports an axially movable shaft that supports the second dual universal joint. An adjustor allows the first and second sub-struts to axially translate relative to each other to increase or decrease length.
