Abstract: An articulated bone reconstruction bar includes a series of short segments connected by fixable axles. The length of the bar is adjusted by varying the number of segments. Before the fixable axles are tightened, the bar is positioned across a discontinuity on a bone. It is adjusted to match the contour of the bone, and the fixable axles are tightened to fixate the connections between the segments and make the bar rigid. The bar is then attached to the bone with mounting screws extending through the segments. Fixable axles with long posts may be used for mounting a dental support plate at the gum line in an area where bone has been lost or removed. If failure occurs, the fixable axles enable the broken segments to be replaced without replacing the entire bar.
