Abstract
A bone adjuster has a first lift plate to be fastened to one of two opposed bone fragments to be adjusted, a second lift plate to be fastened to the other bone fragment and an adjusting shaft which is extended between both the lift plates and to adjust a space between the fragments. The first lift plate comprises a mounting plate and a screw-in connecting portion which is connected with the mounting plate via a hinge and in which the adjusting shaft is screwed to be supported. The second lift plate also comprises a mounting plate and a catching portion which is rotatably fixed to the mounting plate via a hinge to catch the leading end of the adjusting shaft . The screw-in connecting portion and the catching portion are supported on the mounting plates and at a desired angle by the hinges and , so that the mounting plates can be installed parallel to each other even when the bone fragments are skewed so as to appropriately hold the adjusting shaft
