Morphological Characteristics of the Diaphysis of Long Bones Under the Influence of Glucocorticosteroids

This study investigates the morphological changes occurring in the diaphysis of long bones under the influence of glucocorticosteroids (GCS). The aim is to understand the pathophysiological mechanisms contributing to bone fragility associated with prolonged GCS therapy. The research examines histological, microstructural, and architectural alterations in the bone tissue, focusing on the cortical and trabecular bone, osteocyte apoptosis, and osteoblast and osteoclast activity. Findings reveal significant thinning of the cortical bone, disrupted osteonal organization, and reduced trabecular thickness, with an overall decrease in bone density. These structural changes compromise bone strength and increase fracture susceptibility. The study underscores the importance of careful monitoring and intervention strategies in patients undergoing long-term GCS treatment to mitigate skeletal damage.
