Porous tantalum scaffolds: Fabrication, structure, properties, and orthopedic applications

Materials & Design, 2021
Porous tantalum scaffolds have been developed and clinically utilized as superior implantable biomaterials for orthopedic applications owing to their exceptional corrosion resistance, biocompatibility, osteointegration, and osteoconductivity.

Reconstruction of Proximal Metaphyseal Femoral Defects Using Trabecular Metal Augments in Revision Total Hip Arthroplasty

Arthroplasty Today, 2021
Porous tantalum augments are widely used in revision total hip arthroplasty for the reconstruction of severe bone defects. Here, we present the first 3 cases who underwent femoral revision arthroplasty using standard distal femoral and proximal tibial ...

Synthesis of coral-like tantalum oxide films via anodization in mixed organic-inorganic electrolytes. [PDF]

PLoS ONE, 2013
We report a simple method to fabricate nano-porous tantalum oxide films via anodization with Ta foils as the anode at room temperature. A mixture of ethylene glycol, phosphoric acid, NH4F and H2O was used as the electrolyte where the nano-porous tantalum

Radial head replacement using personalized 3D printed porous tantalum prosthesis

Journal of Materials Research and Technology, 2022
Fractures of the radial head account for 33% of elbow fractures. More and more studies have found that the radial head plays an important role in the normal function of the elbow joint, and many complications will occur after resection of the radial head.

Influence of porosity on osteogenesis, bone growth and osteointegration in trabecular tantalum scaffolds fabricated by additive manufacturing

Frontiers in Bioengineering and Biotechnology, 2023
Porous tantalum implants are a class of materials commonly used in clinical practice to repair bone defects. However, the cumbersome and problematic preparation procedure have limited their widespread application.

Porous tantalum and tantalum oxide nanoparticles for regenerative medicine

Acta Neurobiologiae Experimentalis, 2014
For centuries, inflammatory/foreign body reactions have plagued the attempts of clinicians to use metals for tissue and bone reconstructions. Since corrosion contributes to the rejection of metal by the body, an extremely bioinert metal – tantalum – has been successfully used in medicine.
