Anchoring nails and systems

A fixation nail for an interbody fusion procedure, the fixation nail comprising:

• a body having an arcuate primary axis extending from a distal end to a proximal end thereof,
• wherein the body has an outer surface that enables complete insertion and removal of the fixation nail into an interbody without threaded engagement, and
• wherein the body includes an elongated recess spanning a majority of a length of the body, the elongated recess sized to at least partially encompass at least one of tissue or bone during insertion into a patient,
• wherein the fixation nail is positioned within an inserter and a nail guide for deployment, the inserter includes a probe for passing through a corresponding slot on the nail guide, when passing the inserter through the slot, a shaft of the inserter is configured to engage the nail guide,
• the fixation nail and the inserter are fixed relative to one another when engaged,
• wherein the nail guide includes two nail slots, and a first and second biasing mechanism, the first and second biasing mechanism including an arcuate contact surface configured to contact a portion of the nail to limit movement within the nail slot when engaged and permits the nail to pass the biasing mechanism when force is applied.
