Bone Histomorphology in Tibial Diaphysis of Growing Chicks Administered Excessive Vitamin A.

Mechanical assessment of effects of grape seed proanthocyanidins extract on tibial bone diaphysis in rats.

We studied the effects of grape seed proanthocyanidins extract (GSPE) given as a ratio of 3 mg in 100 g in a standard diet, on the tibial bone diaphysis in low-calcium fed rats. Measurements of bone density, mineral content, geometry, and bone strength using peripheral quantitative computed tomography (pQCT). Further, the whole tibia bones were tested for mechanical resistance using a material-...

A Brown Tumor of Tibial Diaphysis Masquerading as Malignancy

A cortical lesion of the tibial diaphysis in a young patient poses a diagnostic challenge to the clinician. Brown tumors, although not very common, may mimic malignancies on radiographs. Brown tumors are destructive lytic lesions of the bone due to increased osteoclastic activity and fibroblastic proliferation in patients with uncontrolled hyperparathyroidism (HPT). They occur after primary or ...

Evaluating Glucocorticoid Administration on Biomechanical Properties of Rats’ Tibial Diaphysis

BACKGROUND Osteoporosis is a disease, which causes bone loss and fractures. Although glucocorticoids effectively suppress inflammation, their chronic use is accompanied by bone loss with a tendency toward secondary osteoporosis. OBJECTIVES This study took into consideration the importance of cortical bone in the entire bone's mechanical competence. Hence, the aim of this study was to assess t...

Recurrence of a Unicameral Bone Cyst in the Femoral Diaphysis

Diaphyseal unicameral bone cysts of the long bone are generally known to originate near the growth plate and migrate from the metaphysis to the diaphysis during skeletal growth. In the case of unicameral bone cysts of diaphyseal origin, recurrence at the same location is extremely rare. We report a case of recurrence of a unicameral bone cyst in the diaphysis of the femur that developed 8 years...
