    • A fracture fixation device includes a plate portion and an intramedullary nail portion which is offset relative to the plate portion by a neck portion. The plate portion includes longitudinally displaced peg holes which orient pegs along an imaginary surface parallel to subchondral bone of an articular surface. The upper surface of the plate portion includes a dimple to reference a jig. The nail portion includes threaded screw holes oriented normal to an endosteal surface, and a smaller K-wire alignment hole parallel to the screw holes. The jig has a first portion which references with the dimple and a second portion in alignment over the screw holes of the nail portion. The back of the first portion of the jig is curved upward to facilitate maneuvering of the jig. The first and second portions of the jig includes K-wire guide holes which direct K-wires relative to holes in the device.
    • 骨折固定装置包括板部分和髓内钉部分,其通过颈部相对于板部分偏移。 板部分包括沿着平行于关节表面的软骨下骨的假想表面定向钉的纵向移位的钉孔。 板部的上表面包括用于参考夹具的凹坑。 指甲部分包括垂直于内壁表面的螺纹孔,以及平行于螺钉孔的较小的K形线对准孔。 夹具具有第一部分,其与凹坑相关联,第二部分对准指甲部分的螺钉孔。 夹具的第一部分的后部向上弯曲以便于夹具的操纵。 夹具的第一部分和第二部分包括相对于装置中的孔引导K线的K线引导孔。
