 Advanced Radiographic Imaging Results in Patients with Trabecular Metal™ Spinal Implants

Trabecular Metal implants (TM) mimic desirable bone qualities of porosity and elasticity while maintaining excellent compressive strength. Despite these biomechanical advantages, metal spinal implants often cause metal artifact on postoperative computed tomography (CT) or magnetic resonance imaging (MRI). Although tantalum-based spinal implants have been in use since 2002, the imaging properties of these devices have not been fully studied.
