Anterior Cervical Plates For Spinal Surgery Employing Anchor Blackout Prevention Devices, And Related Systems And Methods

摘要

Anterior cervical plates for spinal surgery employing anchor backout prevention devices, and related systems and methods are disclosed. A spinal column includes vertebrae in an articulating structure. Medical intervention may involve limiting the relative motion between vertebrae by fusing at least first and second vertebrae together with osteosynthesis systems. The systems include a plate attached to anterior surfaces of the first and second vertebrae with anchors extending through passageways in the plate. By including one or more anchor backout prevention devices to the plate, movements causing the anchors to disengage from the vertebrae may be avoided. The devices may include a positioning guide, and locking magnets. The implementation of a combination of these devices into the plate may provide greater robustness against failure than any of the devices individually. In this manner, the useful life of the plate within a patient may be lengthened.
