Percutaneous interbody fusions.

Percutaneous interbody fusion procedures have evolved as a result of the need for precise and specific access corridors to facilitate the application of technology to perform these procedures. Endoscopic visualization has expanded minimally invasive capabilities, particularly in the thoracic and lumbar spine. Refinement of grafting concepts and structural composition continues. Based on the historical evolution of the described percutaneous interbody fusion procedures, the future of minimally invasive interbody arthrodesis shows promise through the ongoing definition of access corridors and the refinement of operative tools and techniques.
