摘要：A device and a method for stabilizing vertebrae in a human spine for thepurpose of fixing one vertebra with respect to other vertebrae and with respect to other
parts of the spinal column. This device comprises bone screws that clamp to a plate tomaintain the plate in contact with the vertebrae. The device may be fabricated from non-metals, metal, alloys, or composite materials. A tapered screw head is pulled into theplate with the taper extending through the plate into the underlying bone. Extending thetaper into the bone moves the screw thread stress raiser into an area of lesser
deflection. This strengthens the fixation by increasing the rigidity and reducing the risk ofscrew breakage. Extending the taper into the underlying bone has also been shown tostrengthen the taper lock.
