Claims (11)

A spherical bead (30) having a conical hole (34) interposed between the locking bone screw head (2) and the receiving hole (14) in the bone plate (10). A spherical bead according to claim 1, wherein the hole (34) tapers at a self-locking angle (33). A spherical bead according to claim 2, wherein the angle (33) is between about 2.7 degrees and about 8 degrees, preferably about 5.7 degrees, corresponding to a 1:10 taper. Implant construct comprising a bead (30) according to any one of claims 1 to 3, a locking screw (40) and optionally a locking plate (10). The total angle (42) of the conical screw head (41) is about 0.2 to about 0.4 degrees, preferably about 0.3, than the hole (34) angle (33) in the bead (30). 5. The implant construct of claim 4, wherein the graft construct is of high degree. 4. or wherein the total angle (15) of the conical holes (14) in the plate (10) is approximately the same as the total angle (33) of the conical holes (34) in the beads (30); 5. The graft construct according to 5. 5. The implant construct of claim 4, comprising a bone locking plate (10), a bone locking screw (40), and a spherical bead (30), wherein the bead (30) comprises a conical hole (34). , is interposed between the conical head (41) of the bone locking screw (40) and the receiving hole (14) in the bone locking plate (10); Implant construct, characterized in that the side holes (14) are conical. 8. The implant construct of claim 7, comprising a bone locking plate (10), a bone locking screw (40) and a spherical bead (30), wherein the bead (30) comprises a conical hole (34). , is interposed between the conical head (41) of the bone locking screw (40) and the receiving hole (14) in the bone locking plate (10); The side holes (14) are characterized by being conical and the total angle (15) of the conical receiving holes (14) in the plate (10) is equal to the conical hole in the bead (30). An implant construct that is approximately the same as the total angle (33) of (34). The total angle (42) of the conical screw head (41) is about 0.2 to about 0.4 degrees greater than the total angle (33) of the conical hole (34) in the bead (30), preferably 9.
