PEEK or titanium? That has been a question that surprisingly has not been extensively explored in head-to-head clinical research. Nevertheless a pair of completed studies and a third designed to randomly compare PEEK, Titanium and ceramic cages that is now under way provide some basis for comparison.
In a 2012 German study in the BioMed Central Musculoskeletal Disorders Cabraja, Oexdemir, et al, compared titanium (TTN) and polyetheretherketone (PEEK) cages in 154 patients who underwent single level anterior cervical discectomy and fusion (ACDF) performed between 2002 and 2007. (published site)
