Intervertebral devices, and associated systems and methods

A system for treating a spine of a patient, the system comprising:

• a trocar configured to provide access to a diseased disc within a disc space of the spine;
• an anchoring device configured to restrict movement of the trocar in at least one direction relative to the disc space;
• a discectomy device insertable through the trocar to disrupt at least a portion of the diseased disc;
• an intervertebral device insertable through the trocar into the disc space and configured to expand within the disc space;
• and
• a fill material configured to fill the intervertebral device.

A method of treating a spine of a patient, the method comprising:

• inserting a trocar to proximate a diseased disc within a disc space of the spine;
• anchoring the trocar relative to the disc space to restrict movement of the trocar in at least one direction relative to the disc space;
• inserting a discectomy device through the trocar;
• disrupting at least a portion of the diseased disc with the discectomy device;
• inserting an intervertebral device through the trocar into the disc space;
• expanding the intervertebral device within the disc space;
• and
• filling the intervertebral device with a fill material.
