- Nitinol in Orthopedic Applications: Clinical Insights, Performance Challenges, and Future Directions Niyou Wang Veluru Jagadeesh Babu Namith Rangaswamy Si Jian Hui Joshua K James Thomas Patrick Decourcy Hallinan Senthil Kumar A Naresh Kumar Journal of Biomedical Materials Research Part B: Applied Biomaterials ABSTRACTThe increasing prevalence of spinal disorders has spurred continuous innovation in implant design and biomaterials. Among emerging options, Nitinol has gained significant interest due to its unique combination of shape memory effect, superelasticity, and mechanical compatibility with bone tissue. These characteristics make it a promising candidate for spinal implants that support minimally invasive surgery and motion preservation. This review offers a comprehensive overview of Nitinol's clinical applications in orthopedics, with a particular focus on spinal procedures. It explores key material properties, device types, and performance benefits, including reduced stress shielding and improved implant‐tissue integration. A wide range of Nitinol‐based devices such as screws, plates and rods, nails, artificial discs, staples, and dynamic systems are discussed alongside clinical outcomes and case studies. Emerging directions such as additive manufacturing for patient‐specific implants, and smart Nitinol systems with integrated sensing or actuation capabilities are discussed. In addition, challenges in thermal control, manufacturing reproducibility, and evolving regulatory standards are addressed. By synthesizing current advancements and unmet needs, this review highlights the clinical potential of Nitinol implants and outlines future directions for their safe, effective, and scalable integration into orthopedic practice. 10.1002/jbm.b.35615 http://creativecommons.org/licenses/by/4.0/
