Stand alone interbody spinal system

An orthopedic fusion system comprising:

• a cage;
• a curved first channel coupling a lateral wall of the cage to a superior surface of the cage;
• a curved second channel coupling the lateral wall of the cage to an inferior surface of the cage;
• a third channel coupling the superior surface of the cage to the inferior surface of the cage;
• a curved first anchor to slide within the first channel, the first anchor including:
• (a) a threaded orifice, and (b) a projection to abut a wall of the first channel to prevent a proximal portion of the first anchor from passing through the first channel;
• a curved second anchor to slide within the second channel;
• and
• first and second arms that are monolithic with each other;
• wherein in an implanted orientation:
• (a) the first and second arms collectively at least partially obstruct the first and second channels, and (b) a portion of the first arm is lateral to at least a portion of the first anchor and prevents the first anchor from backing out of the first channel.
