A pair of clamps are attached to a damaged 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 single pivotal alignment bar, with the clamps then being adjusted to properly align the bone for a surgical attachment using a bone plate which is secured between the respective bone and each respective clamp, holding the bone in place with the bone in proper alignment for the attachment of screws through the plate into the bone, stabilizing the fracture site during the plate attachment procedure.
