Trabecular Metal™ Primary Hip Prosthesis

Product Description

Trabecular Metal Primary Hip Prosthesis combines the proven characteristics of Trabecular Metal Technology with a bone-conserving proximal design.

Trabecular Metal Material provides a high coefficient of friction against cancellous bone for excellent scratch fit and initial implant stability. In addition, its highly porous, strut configuration nature and, open pore-configuration enables biologic in-growth, which can help lead to long-term fixation.1

Its coefficient of friction against cancellous bone is substantially higher than sintered beads.2 This facilitates direct bone apposition,3,4 creating a scratch fit that maximizes initial stability at implantation. It has a higher bone interface shear strength than sintered beads (MPa).1,5
