How does Osteoporosis develop pathologically
A 78-year-old female was out walking her small dog when her dog suddenly tried to chase a rabbit and made her fall. She attempted to try and break her fall by putting her hand out and she landed on her outstretched hand. She immediately felt severe pain in her right wrist and noticed her wrist looked deformed. Her neighbor saw the fall and brought the woman to the local ER for evaluation. Radiographs revealed a CoIles’ fracture (distal radius with dorsal displacement of fragments) as well as radiographic evidence of osteoporosis. A closed reduction of the fracture was successful, and she was placed in a posterior splint with ace bandage wrap and instructed to see an orthopedist for follow up.
Question:
Discuss what is osteoporosis and how does it develop pathologically?
Sample Solution
Osteoporosis, the most frequent from of metabolic bone diseases, is defined as a “skeletal disorder characterized by compromised bone strength predisposing a person to an increased risk of fracture.” Osteoporosis is a metabolic bone disease that, on a cellular level, results from osteoclastic bone resorption not compensated by osteoblastic bone formation. This causes bones to become weak and fragile, thus increasing the risk of fractures. Traditional pathophysiological concepts of osteoporosis focused on endocrine mechanisms such as estrogen or vitamin D deficiency as well as secondary hyperparathyroidism. Interactions between bone and the immune system, the gut microbiome, and cellular senescence are existing insights into mechanisms contributing to the onset of osteoporosis.
