Abstract
➢ Implant surface characteristics play a critical role in promoting osseointegration and long-term spinal fusion success. ➢ Titanium and polyetheretherketone (PEEK) are the most commonly utilized materials in interbody cages, each with distinct advantages and limitations. ➢ Surface modifications such as roughening, porosity, and hydroxyapatite coatings enhance osseointegration and early fusion outcomes. ➢ Emerging materials, including silicon nitride and porous tantalum, demonstrate favorable biological and mechanical properties but require further clinical validation. ➢ No single implant material or surface technology has shown consistent clinical superiority, highlighting the need for ongoing research and evidence-based selection.
