    • Screw system is useful for transiliac fixation of a sacrum and/or sacroiliac joint and/or for application in other skeletal areas, and includes a cannulated bone screw preferably capable of spanning iliac crests of a patient, having an elongate, hollow body with openings on a first end of the body and on an opposing, second end of the body; a tip on the first end of the body, which preferably is a thread-cutting tip that can engage and thread the ilia or other bone of the patient; a head about the second end of the body, which can be engaged with a surgical tool; and threads on at least part of the body between the first and second ends; a locknut with threads for interference fitting corresponding generally to those of the screw for threading on the screw; and preferably also a washer. Major-minor, pitch-diameter, locking interference fitting can be provided. Associated kit includes at least one such screw system; a guidewire, which is essentially as long as or longer than the elongate hollow body of the screw of the at least one screw system, and over which the screw can pass by the openings in the hollow body of the screw, and which beneficially is rigid and has a drill bit tip; and preferably, a cannulated starter drill and/or a tool set to engage the head of the screw for twisting the screw so that it can thread through bone and/or engage the nut so that it can be tightened onto the first end of the screw.
    • 螺旋系统可用于骶骨和/或骶髂关节的透视固定和/或用于其它骨骼区域,并且包括优选能够跨越患者髂嵴的插管骨螺钉,其具有带有开口的细长中空体 身体的第一端和身体的相对的第二端; 主体的第一端上的尖端,其优选地是可以接合并螺纹患者的髂骨或其他骨的切线尖端; 围绕身体的第二端的头部,其可以与外科手术工具接合; 并且在所述第一和第二端之间的所述主体的至少一部分上的螺纹; 具有用于干涉配合的螺纹的锁紧螺母,其通常对应于用于螺钉上螺纹的螺钉的螺纹; 并且优选地也是垫圈。 可以提供主要小型,节径,锁定干涉配件。 相关套件包括至少一个这样的螺钉系统; 导丝,其基本上等于或长于至少一个螺杆系统的螺杆的细长中空体,并且螺钉可以通过螺钉的中空体中的开口穿过,并且其有利地是刚性的 并具有钻头尖端; 并且优选地,套管起动机钻头和/或工具组合以接合螺钉的头部以扭转螺钉,使得其能够螺纹穿过骨头和/或接合螺母,使得其可以被紧固到螺钉的第一端上 。

    • A device for clamping a fixation element which may allow for repositioning of the fixation element. The device may include a body comprising a front end, a rear end, an outer surface, a through bore extending between the front end and the rear end, a structure enabling deformation of at least a portion of the body, and a thread along at least a portion of the outer surface. The body may be tapered and the through bore may be sized and configured to receive a fixation element. The clamping device may also comprise a receiving member having a tapered bore with an inner thread sized and configured to receive the thread of the body. Insertion of the body into the tapered bore of the receiving member may result in at least a portion of the body being deformed. As the body is inserted into the tapered bore, the dimension of the through bore may decrease so that the body firmly engages the fixation element. Such a construction may allow for the body to be loosened from the tapered bore, the fixation element, body or receiving member to be repositioned, and the body re-tightened into the tapered bore.
    • 用于夹紧固定元件的装置,其可以允许固定元件的重新定位。 该装置可以包括主体,其包括前端,后端,外表面,在前端和后端之间延伸的通孔,能够使身体的至少一部分变形的结构,以及沿着 外表面的至少一部分。 主体可以是锥形的,并且通孔的尺寸和构造可以被接收固定元件。 夹紧装置还可以包括具有锥形孔的接收构件,其具有内螺纹的尺寸和构造以容纳主体的螺纹。 将主体插入接收构件的锥形孔可能导致身体的至少一部分变形。 当主体插入到锥形孔中时,通孔的尺寸可能减小,使得主体牢固地接合固定元件。 这种构造可以允许主体从锥形孔,固定元件,主体或接收构件松动以被重新定位,并且主体被再次拧紧到锥形孔中。

    • The device includes a support structure (2) having an orifice (3) that delimits a seat (5) for receiving a nut (6) intended to cooperate with a locking screw (4). The seat (5) comprises an upper part (5a) and a lower part (5b), both shaped as truncated spheres and concentric to each other. Furthermore, the nut (6) has a spherical contour (11), and the screw head (15) has a lower part (15b), also with a spherical contour, and an upper part (15a) provided with a thread (17). The upper (15a) and lower (15b) parts of the screw head (15) cooperate respectively with the complementary thread (14) of the nut (6) and with the lower part (5b) of the receiving seat (5) such that, in the final phase of screwing the spherical contour (11) of the nut (6) bears against the upper spherical part (5a) of the seat (5), and of the lower part of the screw head (15b) against the lower spherical part (5b) of the seat (5).
