    • An anterior transpedicular bone fixation device (100) includes a first plate (105) having at least one fastener hole (120a) configured to receive at least a portion of a first bone fastener and a first rotatable eccentric member (112). The first eccentric member has a first aperture (106) for receiving at least a portion of a central fastener (108). A second plate (110) has at least one fastener hole (120c) configured to receive at least a portion of a second bone fastener and a second rotatable eccentric member (114) with a second aperture (107) for receiving at least a portion of the central fastener, wherein the first and second rotatable eccentric members enable the first plate and second plate to translation with respect to one another. The orientation of the first plate with respect to the second plate can be fixed by advancing the central fastener through the apertures.
    • 前经椎弓根骨固定装置(100)包括具有至少一个紧固件孔(120a)的第一板(105),所述至少一个紧固孔构造成容纳第一骨固定件和第一可旋转偏心构件(112)的至少一部分。 第一偏心构件具有用于接纳中心紧固件(108)的至少一部分的第一孔(106)。 第二板(110)具有至少一个紧固件孔(120c),其被配置为容纳第二骨紧固件的至少一部分和具有第二孔(107)的第二可旋转偏心构件(114),用于接收至少一部分 所述中心紧固件,其中所述第一和第二可旋转偏心构件使得所述第一板和第二板相对于彼此平移。 第一板相对于第二板的定向可以通过使中心紧固件穿过孔固定。
