At the heart of the ApiFix system is the self-adjusting rod that acts as an internal brace to help straighten the spine. The rod design features two polyaxial joints, allowing a greater degree of motion compared to fusion surgery.

The ApiFix system is implanted on only one side of the spine using a posterior approach, it is less invasive than fusion and other fusion-less procedures that typically require a more complex, anterior approach. This difference may lead to a faster recovery time. Patients are generally discharged from the hospital in 1-2 days and return to school within 2 weeks following the ApiFix procedure.
