NAVIGATED PERCUTANEOUS LUMBAR AND THORACIC SPINE FACET FUSION

摘要

A system for percutaneous or open facet joint fusion includes an imaging system configured to identify a docking location on a facet joint between a first vertebra and a second vertebra of a patient. The system also includes a cannula configured to be positioned at the docking location on the facet joint. The cannula includes one or more markers mounted thereto, and the imaging system is configured to identify the one or more markers to position the cannula at the docking location. The cannula also includes one or more actuators configured to move the one or more markers. The system further includes a rotary tool that is configured to mount within the cannula. The rotary tool is configured to create a void in the facet joint by way of the cannula, and the void is configured to receive a bone graft or bone growth promoting material.
