Osteoid
Definition:
(a.) Resembling bone; bonelike.
Example Sentences:
(1) The fibrous matrix and cartilage formed within the nonunion site transformed to osteoid and bone with increased vascularity.
(2) Osteomalacia is characterized by large osteoid seams and a preserved volume of bone trabeculae.
(3) The radiological and macroscopic features were identical with osteoid osteoma.
(4) Marked declines in stainable bone-surface aluminum were associated with increases in bone formation rate and osteoblastic osteoid following deferoxamine.
(5) A sclerotic border and osteoid seams were noted, two features that seem not to have been previously reported in early lesions.
(6) Trabecular bone volume, osteoid amount, and eroded surfaces were measured.
(7) Calcification initially occurs in maxtrix vesicles (or calcifying globules) which are very numerous between the collagen fibrils of the osteoid tissue, and successively spreads into the surrounding interfibrillar matrix.
(8) The frequencies in the two groups are as follows: In the benign group, osteoma had the highest incidence and then, with decreasing frequencies: osteochondroma, chondroma, synovioma, giant cell tumor, ossifying fibroma, osteoid osteoma, chondromyxoid fibroma.
