Method and device utilizing tapered screw shanks for spinal stabilization |
摘要 |
A method and a device are provided for stabilizing vertebrae in a human spine for the purpose of fixing one vertebra with respect to other vertebrae and with respect to other parts of the spinal column. This device comprises a plate and bone screws fabricated from metals. The bone screw maintains the plate in contact with the vertebrae. A tapered screw head is pulled into a machined tapered hole, locking the screw to the plate. The taper is configured to be self-locking preventing the screw from backing out. The taper may be within the fixed structure of the plate, or within an insert placed into the plate.
