The trabecular bone score is a measure of bone texture correlated with bone microarchitecture and a marker for the risk of osteoporosis. Introduced in 2008, [ 1 ] its main projected use is alongside measures of bone density in better predicting fracture risk in people with metabolic bone problems.
Inside of a bone showing the trabecular structure A typical carcinoid tumor of the lung showing a trabecular pattern of elongated groups of cells.. A trabecula (pl.: trabeculae, from Latin for 'small beam') is a small, often microscopic, tissue element in the form of a small beam, strut or rod that supports or anchors a framework of parts within a body or organ.
A scanner used to measure bone density using dual energy X-ray absorptiometry. Bone density, or bone mineral density, is the amount of bone mineral in bone tissue.The concept is of mass of mineral per volume of bone (relating to density in the physics sense), although clinically it is measured by proxy according to optical density per square centimetre of bone surface upon imaging.

A T score tells the patient what their bone mineral density is in comparison to a young adult of the same gender with peak bone mineral density. A normal T score is -1.0 and above, low bone density is between -1.0 and -2.5, and osteoporosis is -2.5 and lower. A Z score is just a comparison of what a patient's bone mineral density is in ...

Mirels' score is a tool useful in the management of bone tumors, by identifying those patients who would benefit from prophylactic fixation if they have a high enough risk of pathological fracture. Scoring
A condensation of trabecular fibres forms the moderator band which carries the right branch of the bundle of His. The trabeculae carneae also serve a function similar to that of papillary muscles in that their contraction pulls on the chordae tendineae , preventing inversion of the mitral (bicuspid) and tricuspid valves towards the atrial ...
There are five principal architectures of arachnoid trabeculae structures, whose shapes may be described as single strands, branched strands, tree-like shapes, sheets, and trabecular networks. [7] Some authors describe the structures in the subarachnoid space as having three forms, namely "trabeculae", "septa" and "pillars". [8] [9] [10] [11]
