Trabecular Metal (porous tantalum) offers a viable solution to several challenges in orthopedic reconstructive surgery, including monoblock acetabular cups, avascular necrosis intervention devices, and total hip reconstruction in situations of massive femoral bone loss. Porous tantalum approaches the ideal biomaterial: it is porous, strong, flexible, and biocompatible. For use in components for total hip arthroplasty, porous tantalum provides a substitute for lost bone, immediate bone loading, bone ingrowth, and soft-tissue attachment. It can be machine-shaped into custom designs in situations of massive bone loss.
