Changes in biological factors can affect the loss of bone metabolism, the synthesis of bone collagen fibers or the structure of bone trabeculae, thereby increasing the risk of osteoporosis.
The Masson's trichrome staining revealed reddish neoplastic components delineated by thin bluish connective tissue trabeculae (Figure 1C).
Magnetic resonance imaging (MRI) is usually not needed, but it reveals surrounding oedema.6 Histopathology demonstrates a fibrovascular tissue with immature bone trabeculae surrounded by osteoblast.8 There is no nuclear atypia.
In the alloplastic graft 1 group, most of the socket regions were occupied by newly formed and loose trabecular bone; these trabeculae are distributed uniformly in the peripheral and central region of the alveolar sockets.
Vertebral lesions demonstrate prominent vertical trabeculae, the 'corduroy" sign.
Further evaluation with pre- and post-contrast magnetic resonance imaging (MRI) showed a 2.1 x 1.6 x 3.1 cm lesion in the proximal metaphysis of the ulna, which was hyperintense on T2-weighted imaging (T2WI) and isointense to skeletal muscle on T1-weighted imaging (T1WI) [Figure 2a and b] and showed internal trabeculae. Mild rim enhancement was present on the post-contrast fat-saturated (FS) T1WI [Figure 2c].
It consists of a single or multiple foci of fibrous tissue composed of irregular bone trabeculae that can lead to weakness or pathological fracture of the affected bones.
Histopathologically, compact bone tissue composed of thickened trabeculae was observed in the sections.
In the control group, most of the trabeculae were cracked, discontinuous, and reduced, and the mean percentage of empty lacunae was 67.7% [+ or -] 13.8%, confirming the presence of ONFH.
