Trabecular Metal Material is made of elemental tantalum (atomic number 73), a chemically stable and biologically inert metal used in orthopedic implants.6 This makes it highly biocompatible.7 Tantalum is the ideal material for this structure, because it has high fatigue strength and a compressive modulus that allows it to bend before breaking.3
Trabecular Metal™ Technology
A Unique, Highly Porous Biomaterial
Trabecular Metal Material is made from elemental tantalum with structural, functional, and physiological properties similar to that of bone.1 The material features a 100% open, engineered and interconnected pore structure to support biological fixation and vascularization.1,2 The material has over 20 years of demonstrated clinical use in a variety of orthopaedic applications.3-5

The performance of specific components in human subjects has been well-documented in peer-reviewed journal articles, poster exhibits and abstracts. Independent studies have confirmed the structural and mechanical properties of Trabecular Metal material.1-4
- Made from commercially pure elemental tantalum and designed to withstand physiologic loads.1
100% open engineered and interconnected pore structure to support biological fixation and vascularization.1,2
- Up to 80% porosity.1
Low modulus of elasticity similar to cancellous bone for more normal physiological loading which has the potential to reduce stress shielding when used in a monoblock or monolithic application.3
High coefficient of friction vs. cancellous bone for stable initial fixation.3
- Chemically stable and biocompatible material which creates little adverse biological response.6
Utilizing a proprietary chemical deposition process, elemental tantalum is deposited onto a substrate, Trabecular Metal’s unique microspiked surface topography.
