OSTEOPOROSIS 1 
OSTEOPOROSIS
Stroehlein
OBJECTIVES
Osteoporosis
• Porous bones
• Systemic skeletal disease-loss of bone mass (low bone density)
• Increased bone fragility-risk for fracture
• 44 million Americans, more than one tenth of the population • One of the most common disorders associated with aging ,although NOT a consequence of normal aging
Risk Factors and the Effects on Bone
Typical Loss of Height Associated with Osteoporosis and Aging
Manifestations
• Loss of height
• Pain does not occur unless there is a FX. Fracture of forearm(Distal radius),spine,hip(Proximal femur)
• Curvature of spine-Dowagers hump (progressive kyphosis) • More than 1.5 million Americans suffer osteoporotic fractures annually Nat’l Osteoporosis
Foundation2002)
• 24%hip Fx.s result in death within one year of injury25%will require long term care institution
Progressive Osteoporosis Bone Loss and Compression Fractures
Diagnosis
• Xray, Ultrasound
• Dual energy x-ray absorptiometry (Dexa)
LSSpine,HIP
• measuresBMD(bone mineral density)
• Quantitative CT(QCT)-measures trabecular bone with vertebral bodies
• Quantitative ultrasound studies
Bone Mass Density
• The National Osteoporosis Foundation
Recommends you have a Bone Density Test if:
• Post menopausal over 50 and have at least one risk factor.
• over 65 and never had a test
• You experience early menopause
• You use medication that cause osteoporosis
• You have type 1 Diabetes, Liver disease,
Kidney disease or a family history
T Score
• A T-score that helps determine whether a person is at risk for fractures. • A T-score of -2.5 or lower is defined as osteoporosis. • The lower the score, the greater your fracture risk can be.
NOF/WHO Criteria for Assessing
Disease Severity
• Bone Mass score- the standard deviation in a patient’s bone mineral density (BMD) compared with the peak bone mass in a young adult of the same gender.
• Normal T-score >1.0
• Osteopenia T-score -1.0 to-2.5
• Severe (established) osteoporosis< or= -2.5
