in combination with this invention fig1 is a partially cut away schematic of one embodiment of the bone screw device 10 of this invention there is the shaft 12 with threads 30 and cutting edge 40 elevation line 42 shows the height of the kerf or cutting edge 40 above the root 44 reference point elevation line 46 illustrates the diameter height of threads 30 in this embodiment it may be appreciated therefore that cutting edge 40 forms an excavated zone above root 44 reference location around the device upon insertion into bone this feature is designed to cut a pathway to allow dispersion of tissue reinforcement material the height shape and angle of the cutting edges of this structure control the direction that the material is dispersed preferably this results in the removed material tissue being directed away from the excavation site and allows for insertion of the reinforcing material in an even distribution to aid in the purchase of the screw in anchoring within weakened bone tissue cut away distal portion u201c a u201d shows an internal lumen 20 and an optional open tip 50 that communicates with the lumen 20 as shown also in fig1 fig2 is a partial cutaway view of another embodiment of the invention where an aperture 60 is positioned on the shaft 112 with nearby cutting edge 140 protruding between threads 130 on device 110 the distal portion u201c a u201d of the device is a cutaway showing aperture 60 in conjunction.
