3D-printed tantalum artificial vertebral body or titanium mesh in anterior column reconstruction post-spondylectomy for thoracic vertebral tumors: a retrospective comparative cohort study and finite element analysis
AVBs made of 3D-printed tantalum demonstrate superior biomechanical and clinical performance compared to titanium mesh for anterior reconstruction after TES. Tantalum significantly reduces endplate stress, implant subsidence, and hardware failure rates while promoting earlier fusion. Restricting postoperative trunk axial rotation may help mitigate mechanical complications.
