    Study Notes

    Aging and Osteoporosis: Risk Factors and Conditions

    • Age-related changes can lead to falls, fractures, and loss of mobility
    • Factors critical for healthy aging include bone strength, muscle strength, joint health, neurological function, and nutrition
    • Bone tissue is composed of compact bone (cortical) and spongy bone (trabecular)
    • Bone tissue cell types include osteogenic cells, osteoblasts, osteoclasts, and osteocytes
    • Bone remodeling is a dynamic process crucial for maintaining, repairing, and adapting bone
    • Osteoporosis is characterized by low bone density and increased risk of fracture
    • Osteoporosis is more prevalent in women, with risk factors including age, low calcium or Vit D, genetics, hormone imbalance, race, and medications
    • Peak bone mass is influenced by genetics, sex, puberty, and lifestyle factors
    • Calcium homeostasis is regulated by parathyroid hormone and activated vitamin D
    • Estrogens and androgens play essential roles in bone growth and remodeling
    • Osteoporosis pathogenesis involves high turnover and remodeling imbalance, affecting both spongy and compact bone
    • Clinical manifestations of osteoporosis include fractures, pain, deformity, and additional falls, with common fracture sites being the hip, distal radius, and vertebrae
