Where is the trabecular bone located?
Trabecular bone is situated at the end of the long bones and in the spinal column, where it fills all of the inner vertebral space and has a complex three-dimensional architecture (Thurner et al., 2007).
Which bones are trabecular bone?
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 the trabeculae bone?
Introduction. 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. 1).
Where would you find cancellous and trabecular bone?
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).
What is cortical bone vs trabecular bone?
The material properties of the bone compartments differ: trabecular bone has lower calcium content and more water content compared to cortical bone. Trabecular bone has a large surface exposed to the bone marrow and blood flow, and the turnover is higher than in cortical bone [1].
Is trabecular bone mature?
This immature bone is later replaced by secondary or lamellar bone (mature). Secondary bone is further classified as two types: trabecular bone (also called cancellous or spongy bone) and compact bone (also called dense or cortical bone).
What is a trabecular injury?
Bone bruises (also known as bone contusion, trabecular microfracture) are an osseous injury that results from compression of bone structures.
Is trabecular bone woven?
At the microscopic level, trabecular and cortical bones consist of two forms: woven and lamellar.
What is trabecular bone fraction?
Trabecular bone volume fraction (TBVF) is highly associated with the mechanical competence of trabecular bone. TBVF is ordinarily measured by histomorphometry from bone biopsies or, noninvasively, by means of high-resolution microcomputed tomography and, more recently, by micro-MRI.
What is trabecular bone score (TBS)?
Trabecular bone score (TBS) is a texture index derived from standard lumbar spine dual energy X-ray absorptiometry (DXA) images and provides information about the underlying bone independent of the bone mineral density (BMD). Several salient observations have emerged.
What is trabecular bone?
Trabecular bone is a highly porous (typically 75–95%) form of bone tissue that is organized into a network of interconnected rods and plates called trabeculae which surround pores that are filled with bone marrow. Girish Ramaswamy, Carl E. Misch, in Dental Implant Prosthetics (Second Edition), 2015
How do you identify trabeculae?
Begin by identifying the trabeculae, the spongy network of bone tissue in the center of the bone. The surface of trabeculae are covered by a thin layer of inactive cells called endosteum.
How important is 3D image registration for evaluation of trabecular bone structure?
In addition, the importance of the 3D image registration to ensure accurate evaluation of changes in trabecular bone structure in a long-term study design was quantitatively demonstrated.
