摘要： An aiming guide aligns a surgical tool with a hole in a bone plate. The aiming guide includes an arm portion having a longitudinal axis, top and bottom surfaces, and first and second ends. The aiming guide further includes a handle portion having upper and lower ends. The handle portion is, at its lower end, connected to the bone plate. The handle portion is, at its upper end, connected to the arm portion. Bores extend from the top surface to the lower surface of the arm portion. Each bore is configured and dimensioned to receive a tool guide in at least two different preset positions which locates the channel in at least two different hole positions. The bore includes two diametrically opposed slots extending along at least a portion of a length of the bore, the slots configured and dimensioned to mate with diametrically opposed knobs extending radially outward from a tool guide. The tool guide has a head and a sleeve portion, which has a centered channel. The sleeve portion and channel are eccentric with respect to the head portion. The tool guide is inserted in a first preset position in order to align a surgical tool with one portion of a two-portion bone plate hole, or in a second preset position rotated 180° from the first preset position, in order to align a surgical tool with the second portion of a two-portion bone plate hole.

摘要： A bone plate (10) has an upper surface (20), a lower surface (22), and at least one first hole (90) extending through the upper and lower surfaces. The first hole (90) has two or three vertically separate regions, each region communicating with or abutting the adjacent region. The first hole (90) has a first upper region (92), which is unthreaded and which, from the plate's upper surface (20) to the plate's lower surface (22), has a curved inward taper. The first hole (90) has a second middle region (94), which is threaded and which, from the plate's upper surface (20) to the plate's lower surface (22), has a conical inward taper. The first hole (90) has a third lower region, (96), which is unthreaded and which, from the plate's upper surface (20) to the plate's lower surface (22), has a conical outward taper. The bone plate (10) is straight, curved, or both straight and curved. The bone plate (10) may have at least one second hole, different from the first hole. The second hole is an elongated hole, which has a compression ramp or which has a threaded portion through part of its perimeter and a non-threaded portion through the other part of its perimeter.
摘要翻译： 骨板（10）具有上表面（20），下表面（22）和延伸穿过上表面和下表面的至少一个第一孔（90）。 第一孔（90）具有两个或三个垂直分开的区域，每个区域与相邻区域连通或邻接。 第一孔（90）具有第一上部区域（92），该第一上部区域不被螺纹连接并且从板的上表面（20）到板的下表面（22）具有向内弯曲的弯曲。 第一孔（90）具有第二中间区域（94），该第二中间区域具有螺纹并且从板的上表面（20）到板的下表面（22）具有锥形向内渐缩。 第一孔（90）具有第三下部区域（96），该第三下部区域是无螺纹的并且从板的上表面（20）到板的下表面（22）具有锥形向外锥形。 骨板（10）是直的，弯曲的，或者既是直的又是弯曲的。 骨板（10）可具有至少一个不同于第一孔的第二孔。 第二孔是一个细长的孔，它具有一个压缩坡道或者具有穿过其周边的一部分的螺纹部分和穿过其周边的另一部分的非螺纹部分。

摘要： A tool is disclosed for use in distracting and compressing fractures of any of a variety of bones. In particular, the tool has a pair of engaging arms, one arm having a hook element to engage a bone plate connected to one side of a fracture, and the other arm having at least one recess for engaging a head of a bone screw or guide wire connected to the other side of the fracture. Actuation of the tool causes the opposing bone segments of the fracture to be pushed apart or drawn together, depending on whether the tool handles are squeezed together or pulled apart. The tool may have a scissors joint that allows the ends of the tool to maintain a parallel alignment during operation, thus reducing the chances for misalignment of the bone segments during operation.
