Personalized porous tantalum implants crafted via 3D printing: new horizons in complex cervical-thoracic spinal fusion.

ABSTRACT:

Background

Complex interbody fusion remains challenging, while traditional surgical instruments are not suitable for complex spinal deformities. Porous tantalum (Ta) has excellent osteogenic properties, but there is currently a lack of research on its application in cervical thoracic interbody fusion.

Objective

To introduce the application of selective electron beam melting (SEBM) 3D printing technology in customized porous Ta vertebral fusion implants and evaluate its mid-term clinical efficacy in complex cervical thoracic fusion surgery. Method: Porous Ta implants were manufactured using SEBM technology. The mechanical properties were optimized and characterized. Three patients who underwent complex cervical and thoracic fusion surgery were prospectively recruited. 3D prin
