How is trabecular metal made?

How is trabecular metal made?

Trabecular Metal Material is produced at a dedicated facility in Parsippany, New Jersey. Utilizing a proprietary thermal deposition process, elemental tantalum is deposited onto a substrate, creating a nanotextured surface topography and building Trabecular Metal Material one atom at a time.

What is trabecular made of?

Structure. Trabecular bone, also called cancellous bone, is porous bone composed of trabeculated bone tissue. It can be found at the ends of long bones like the femur, where the bone is actually not solid but is full of holes connected by thin rods and plates of bone tissue.

What is a trabecular?

1 : a small bar, rod, bundle of fibers, or septal membrane in the framework of a body organ or part. 2 : a fold, ridge, or bar projecting into or extending from a plant part especially : a row of cells bridging an intercellular space.

Is trabecular bone mineralized?

Trabecular bone quality includes both microstructural and intrinsic tissue mineralization properties. However, the tissue mineralization in individual trabeculae of different trabecular types and orientations has not yet been investigated.

What is trabecular metal?

Trabecular Metal Material is made of elemental tantalum (atomic number 73), one of the most chemically stable and biologically inert metals used in orthopedic implants. 5. This makes it highly biocompatible and corrosion-resistant.

What is Zimmer Biomet made of?

Zimmer Biomet’s proprietary TM Material is a porous biomaterial made from elemental Tantalum with structural, functional and physiological properties similar to cancellous bone. With more than 20 years of clinical results, the Company’s TM Material has been used in over two million orthopaedic devices.

Is trabecular bone spongy?

Trabecular bone tissue is a hierarchical, spongy, and porous material composed of hard and soft tissue components which can be found at the epiphyses and metaphyses of long bones and in the vertebral bodies (Fig.

Is trabecular bone lamellar?

A single trabecula is composed of lamellar tissue with osteocytes lying in lacunae with a network of canaliculi similar to that of the cortical tissue.

Is trabecular bone anisotropic?

Trabecular bone is a highly porous, heterogeneous, and anisotropic material which can be found at the epiphyses of long bones and in the vertebral bodies.

What does cancellous bone mean?

Cancellous bone is the meshwork of spongy tissue (trabeculae) of mature adult bone typically found at the core of vertebral bones in the spine and the ends of the long bones (such as the femur or thigh bone).

Is there a recall on Zimmer hip replacements?

The company said the recall was to postpone hip replacements involving the device until Zimmer could issue new implantation instructions. The FDA stated that the recall was caused by false and misleading labeling.

What is CoCr femoral head?

Zimmer Biomet CoCr Femoral Heads and Freedom® Constrained Heads are made from cobalt-chromium molybdenum alloy. They are manufactured to include a 12/14 taper or Type I taper and are offered in a variety of head diameters and neck configurations.

What is the trabecular meshwork?

The trabecular meshwork is a porous circumferential band of interconnecting channels located in the wall of the eye at the intersection between the clear window on the front of the eye, the cornea, and the colored part of the eye, the iris.

What is Trabecular Titanium?

Trabecular Titanium is a biomaterial that is three-dimensional (3D printed), hexagonal cell structure that imitates trabecular bone morphology.

What is the trabecular meshwork in the eye?

The trabecular meshwork is the spongy tissue located near the cornea through which aqueous humor flows out of the eye. The trabecular meshwork lies in the drainage angle (see video above), and 80 – 90 percent of aqueous humor makes its way into circulation via the trabecular meshwork and its associated structures.
