A pair of clamps are attached to a damaged linear or non-linear bone one each side of a fracture site during a surgical reduction, one clamp on each side of the fracture site, after which the two clamps are slidably engaged to a pivotal alignment bar, with the clamps then being adjusted to properly align the linear or non-linear bone for a surgical attachment using a bone plate. The pivotal alignment bar provides at least one pivotal ball joint which may be aligned as a straight bar for a linear bone or adjusted to an angle for non-linear bones to achieve optimal alignment of the bone. Each clamp provides axially adjustable plate retainers which slides along a track on the end of each segment of the each clamp to position the retainers at a location where the bone plate is to be attached to the bone.
