Anterior Lumbar Interbody Fusion Cage Devices and Related Systems and Methods

A method for performing spinal fusion surgery, the method comprising the steps of:

• providing a housing defining one or more ports, wherein the housing comprises an extensible retention structure, and wherein the extensible retention structure comprises a sharpened, non-serrated cutting edge defining an at least substantially circular opening;
• positioning the housing in an intervertebral space between adjacent vertebrae;
• and
• advancing the extensible retention structure out of the housing through the one or more ports such that the cutting edge defining the at least substantially circular opening rotates and extends into one or more endplates of the adjacent vertebrae.

A method for performing spinal fusion surgery, the method comprising the steps of:

• providing a cage device comprising:
• a housing defining an at least substantially circular port;
• an extensible retention structure, wherein the extensible retention structure comprises a sharpened, non-serrated cutting edge defining an at least substantially circular opening in communication with the at least substantially circular port;
• and
• an actuation mechanism configured for selectively advancing the extensible retention structure;
• positioning the cage device in an intervertebral space between adjacent vertebrae with the extensible retention structure wholly contained within the housing using an anterior surgical approach;
• and
• advancing the extensible retention structure out of the housing through the port using the actuation mechanism such that the cutting edge defining the at least substantially circular opening rotates and extends into one or more endplates of the adjacent vertebrae.
