In the lateral pillar of L1 model, the peak displacement of necrotic cortical and
cancellous bones showed an increase from 52.4 [micro]m and 52.1 [micro]m to 67.9 [micro]m (29.5%) and 61.9 [micro]m (18.8%), respectively.
Tritanium is inspired by the microstructure of
cancellous bone and enabled by AMagine, Stryker's proprietary approach to implant creation using additive manufacturing, also known as 3D printing.
Line B corresponds to thewidth of
cancellous bone measured between the internal point of the medial lingual cortical bone and the internal point of the buccal cortical bone.
The vertebral body itself mainly consists of
cancellous (spongy) bone and of dense material (outer thin cortical shell) (Fig.
Allograft bone can be used as
cancellous graft, cortical struts or osteoarticular blocks.
In the framework of the project Researches Regarding the Improvement of the Modeling and Manufacturing Techniques for the Human Spine Implants, were designed, developed and tested three types of screws according to the bone structure: one screw type for
cancellous vertebral bone, a second screw for cortical vertebral bone and a third screw, designed as a combination of the first two, named hybrid.
Fibrous dysplasia represents a benign idiopathic bone disorder in which
cancellous bone is replaced by abnormal fibrous tissue.
VITOSS(TM) Synthetic
Cancellous Bone Void Filler is currently marketed in the U.S., Europe and Australia, and CORTOSS(TM) Synthetic Cortical Bone Void Filler is currently marketed in Europe and Australia.
Specifically, teriparatide acts on
cancellous bone, which is why bone density of the lumbar spine is dramatically increased in subjects taking the injected drug, while density in the cortical bone of the radius remains stable or even declines among treated subjects, he said.
The synthetic
cancellous bone platform, Orthovita's other core technology, (
cancellous bone is less dense, more vascular and is primarily subject to compressive forces), is being used to develop resorbable, calcium phosphate products which include VITOSS(TM) Injectable and VITOSS(TM) Scaffold.
The company added that the proprietary material is a porous biomaterial made from elemental Tantalum with structural, functional and physiological properties similar to
cancellous bone.
Zimmer Biomet's proprietary TM Material is a porous biomaterial made from elemental Tantalum with structural, functional and physiological properties similar to
cancellous bone.1-3 With more than 20 years of clinical results, the company's TM Material has been used in over 2M orthopaedic devices.
