    • An orthopedic plate and fastener system is provided for fixation of bones which has an implant that can selectably be used to achieve fixed angle and variable locking of the fasteners, as well as non-locking of the fasteners. The system includes a variable locking assembly that includes a locking insert, having threads which mates with internal threads of a through opening in the implant. The system also provides for locking fixed angle fixation, and non-locking variable angle fixation, all of which can be used with the threaded holes of the plates. The locking insert is provided on a ring driver, which is similar to or acts as the drill guide used with the locking fasteners of the present. Thus, the invention also relates to a method of enabling surgery where the surgeon can select the mode of fixation of fasteners between variable axis locking, variable axis non-locking, and fixed angle locking fixation, all utilizing the same fastener opening within the implant.
    • 提供矫形板和紧固件系统用于固定骨头,其具有可选择地用于实现紧固件的固定角度和可变锁定的植入物,以及非锁定紧固件。 该系统包括可变锁定组件,其包括锁定插入件,其具有与植入物中的通孔的内螺纹配合的螺纹。 该系统还提供锁定固定角度固定和非锁定可变角度固定,所有这些可以与板的螺纹孔一起使用。 锁定插入件设置在环形驱动器上,该驱动器类似于或用作与本发明的锁定紧固件一起使用的钻子引导器。 因此,本发明还涉及一种能够进行手术的方法,其中外科医生可以选择在可变轴锁定,可变轴非锁定和固定角度锁定固定之间的紧固件的固定模式,所有这些都使用植入物内的相同的紧固件开口。
