Abstract:
1. An apparatus for fixed-angle fixation and compression of a fracture site or osteotomy of a bone, the apparatus comprising: a bone plate that is elongated along a longitudinal axis and has a top side and an underside; the bone plate defining first and second fixation and compression holes that each extend through the bone plate from the top side to the underside, wherein the first and second fixation and compression holes are spaced apart from each other along the longitudinal axis; each of the first and second fixation and compression holes having an inner most radially inwardly facing, perimeteral surface comprising a first surface portion and a second surface portion, the first and second surface portions respectively being defined by opposing first and second circular arcs that each subtend an angle greater than 180 degrees, the first circular arc having a first diameter (D wherein the bone plate comprises at least one thread along an entirety of the first surface portion; wherein the bone plate along the second surface portion is without a thread; and wherein the first and second fixation and compression holes are oppositely oriented with respect to each other along the longitudinal axis so that the first circular arc of the first fixation and compression hole is located proximate to the first circular arc of the second fixation and compression hole and so that the second circular arc of the first fixation and compression hole is located distal from the second circular arc of the second fixation and compression hole.
