Porous Tantalum (Trabecular Metal)
Verifiedmetal· Trabecular Metal· Zimmer TM
Porous tantalum, also known by the trade name Trabecular Metal, is a highly biocompatible pure tantalum foam structure engineered with interconnected porosity to mimic cancellous bone architecture. Its combination of biological integration capability, corrosion resistance, and radiopacity makes it the preferred choice for orthopedic and spinal implants where bone on-growth and long-term fixation are critical; it outperforms alternatives like titanium alloys in applications requiring rapid osseointegration and can eliminate the need for bone cement or supplemental fixation screws.
