  • Lesson Osteoporosis: Diagnostic and Monitoring Techniques addresses these key points

    • Osteoporosis

    • Skeletal disorder
      • Compromised bone strength
      • Increases risk of fracture

    Bone Composition and Bone Structure

    • Mineral salt (calcium hydroxyapatite)
    • Collagen (fibrous protein)
    • Osteocytes, osteoblasts, and osteoclasts (specialized cells)

    Prevalence of Osteoporosis

    • Common problem
    • Affects both women and men
    • 10 million Americans
      • 80% women
      • 20% men

    Bone Qualities that Reduce Strength

    • Microarchitectural disorganization
    • Accumulation of unrepaired fatigue damage
    • Abnormal mineral density distribution
    • Unnecessarily high bone turnover
    • Osteocyte deficiency

    BMD by Dual-Energy X-Ray Absorptiometry (DXA)

    • Amount of bone mineral in a certain (g/cm2)
      • Dependent upon gender, age, and the part of the body
    • Widely used to identify individuals with osteoporosis at risk for fracture

    Diagnosis of Osteoporosis

    • BMD
    • Medical history & lifestyle
    • Physical examination
    • Skeletal X-rays
    • Laboratory tests

  • Lesson Osteoporosis: Diagnostic and Monitoring Techniques is built from these main references. Log into SMi Source for a complete list and details.

    • Fragility fracture: a fracture caused by injury that would be insufficient to fracture normal bone.
