Trabecular Metal Implants
Trabecular Metal is a bio-material composed of tantalum(Ta) on a graphic scaffold. Tantalum is one of the most bio compatible material known to man. This bio-material is developed and patented by Implex Corporation which is now taken over by Zimmer. Inc.[ ZMH ].Cellular structure of Trabecular metal resembles very close to Trabecular bone, a type of bone found in the joints, that is why this material got its name as "Trabecular". Understanding the behavior of material is very important in developing and engineering its products. Trabecular materials are physically and mechanically more similar to human bones than any other bio implants. These implants has more porosity and flexibility that allows the infiltration of bone growth into its pores. Because of it, the bond between Trabecular metal implant and bone is as good as the bond between human bone and ligaments. More over the elastic modulus of this implant is lower (around 3 Gpa) than most metal impla...
