5 that a plate 18 is provided having a plurality of apertures 20 22 24 26 28 and 30 in this embodiment the plate 18 comprises a plurality of notches projections or stops 32 associated with each aperture the members 14 and 16 are normally biased a predetermined distance away from the axis of the screw 12 so that when the screw 12 is received in an aperture such as aperture 20 the screw 12 becomes locked or retained in the plate 18 notice in fig3 that the pawls 14 and 16 comprise beveled curved or angled surfaces 14 a and 16 a which engage the notches 32 a 32 b and 32 c 32 d respectively and deflected inwardly as viewed in fig2 toward an axis of the screw 12 as the screw 12 is screwed into bone after the screw 12 is screwed into the bone to a desired depth an end 14 b fig1 of finger 14 and an end 16 b of finger 16 becomes received between adjacent notches 32 such as in areas 34 and 36 fig4 between adjacent notches 32 notice that a surface 32 a fig4 of at least one notch 32 engages end 14 b of the resilient pawl 14 which prevents rotational movement in a counterclockwise direction as viewed in fig4 at this point ends 14 b.
