A cervical C1–C2 cage is a highly specialized interbody fusion device developed for use in the atlantoaxial region of the cervical spine (between the first cervical vertebra—C1/atlas—and the second cervical vertebra—C2/axis). It is used in procedures aimed at stabilizing the upper cervical spine and achieving solid fusion in cases of instability or deformity.

This cage is typically implanted as part of posterior or combined surgical techniques, often in conjunction with C1–C2 screw-rod fixation systems. It helps in maintaining proper alignment, restoring anatomical spacing, and supporting load transfer, while also promoting bone fusion through the use of bone graft material placed within the cage.

The design is tailored to the unique anatomy of the C1–C2 region, featuring compact geometry, graft windows, and anti-migration surfaces to ensure secure placement and stability. It is commonly manufactured from PEEK, titanium, or titanium-coated materials, offering high strength, durability, and excellent biocompatibility. Radiolucent options (PEEK) allow for clear postoperative imaging.

C1–C2 cages are used in managing conditions such as atlantoaxial instability, trauma (odontoid fractures), congenital abnormalities, rheumatoid arthritis involvement, and degenerative changes, where strong fixation and reliable fusion are critical.
