    • A distal radius plate having a head with a complex palm shaped profile which flares from the sides of the plate to a leading edge that includes a central oblique linking area that helps to mark the placement of the plate relative to the radius. Further, the plate includes an oblique depression that extends from the rounded pinky side of the head and gradually morphs into the elevated styloid prominence in one diagonal direction, and rises less gradually upward into the lunate prominence on the other side of the head. A proximal plate portion mimics the spiral of the radial bone as it spirals along the longitudinal axis, and includes a tighter radial bend. The head includes holes or bores for pegs which extend into the distal portion of the radius to lock fragments into position. In the first embodiment, the angles of the pegs are fixed. In a second embodiment, one or more of the peg holes are provided with a variable axis locking mechanism assembly and the remaining holes are fixed.
    • 一种远端半径板,其具有头部,该头部具有复杂的手掌形状,其从板的侧面向前缘突出,其包括有助于标记板相对于半径的位置的中心倾斜连接区域。 此外,板包括从头部的圆形小脸侧延伸的倾斜凹部,并且在一个对角线方向上逐渐变形成升高的茎突突出部,并且逐渐向上升高到头部另一侧的月球突出部。 近端板部分沿着纵向轴线螺旋地模拟径向骨的螺旋,并且包括较紧的径向弯曲部。 头部包括用于钉的孔或孔,其延伸到半径的远侧部分以将碎片锁定到位。 在第一实施例中,钉的角度是固定的。 在第二实施例中,一个或多个钉孔设置有可变轴锁定机构组件,并且剩余的孔是固定的。

    • The present invention relates to an orthopedic screw and a corresponding screw driver wherein the screw has a torque driving head with a rounded side a spherical wall for multiaxial use, a self starting, self tapping insertion tip and a threaded portion including a cancellous thread. The threaded portion has a major diameter defined by a spiraling thread and a minor diameter. The head is joined to the threaded portion by an area of from about 2 to about 6 turns of the thread along the longitudinal axis in which the minor diameter tapers by an angle of from about 4° to about 12° and the major diameter of the screw remaining substantially the same. The screw includes a multilobe torque driving recess joined to a cylindrical recess that corresponds to a cylindrical post on the torque driver so as to form a press fit which acts to self-center the screw, to help avoid stripping of the screw/driver interface and to hold the screw in place on the torque driver prior to implantation.
    • 本发明涉及一种矫形螺钉和相应的螺丝刀,其中螺钉具有扭矩驱动头,其具有圆形侧面,用于多轴使用的球形壁,自启动,自攻丝插入尖端和包括松质线的螺纹部分。 螺纹部分具有由螺旋螺纹和较小直径限定的大直径。 头部沿着纵向轴线连接到螺纹部分约2至约6圈的螺纹区域,其中小直径锥度约4°至约12°的角度, 螺丝保持基本相同。 所述螺杆包括多个转矩驱动凹部,所述多叶扭矩驱动凹部接合到对应于所述扭矩驱动器上的圆柱形柱的圆柱形凹部,以便形成用于使所述螺钉自对中心的压配合,以有助于避免螺钉/驱动器接口的剥离, 在植入前将螺丝固定在扭矩驱动器上。
