Bone response to porous tantalum implants in a gap‐healing

Jan 12, 2019· Implants containing porous tantalum demonstrated increased peri‐implant bone formation within this gap‐healing model as shown by significant differences in biomechanical and histomorphometric outcomes. Such implants may represent an alternative to influence bone healing in surgical sites with an existing gap.

Does the Risk of Rerevision Vary Between Porous Tantalum

(2) Does the use of porous tantalum cups influence survivorship when rerevision for PJI is the endpoint? METHODS: A total of 2442 first-time THA revisions with porous tantalum cups and 4401 first-time revisions with other uncemented cups were included in this collaborative study between the Australian and Swedish national joint registries.

Tantalum Wikipedia

Tantalum is a chemical element with the symbol Ta and atomic number 73. Previously known as tantalium, its name comes from Tantalus, a villain from Greek mythology. Tantalum is a rare, hard, blue-gray, lustrous transition metal that is highly corrosion-resistant.

Additively manufactured porous tantalum implants

The architecture of the porous structure in combination with the material properties of tantalum result in mechanical properties close to those of human bone and allow for bone ingrowth. The bone regeneration performance of the porous tantalum was evaluated in vivo using an orthotopic load-bearing bone defect model in the rat femur.

The monoblock porous tantalum acetabular cup was designed to minimize osteolysis, but whether it does so is unclear. We evaluated the incidence of osteolytic lesions after THA using a monoblock porous tantalum acetabular component. We retrospectively reviewed 51 patients who had a THA using a monoblock porous tantalum acetabular cup.
