OSTEOPOROSIS QUESTIONS AND ANSWERS
A.A skeletal disease that is characterized by low bone mineral density and changes in
the microarchitecture of bone that increase susceptibility to fracture. - Answers -1.What
is osteoporosis? B
A.The burden of osteoporosis on society and the individual is significant. More than 10
million Americas in the US >50 year old have osteoporosis, and another 34 million are
at risk for it. - Answers -2.What is the burden of osteoporosis on both society and the
individual? B
A.Wrist, spine and hip - Answers -3.What are the three most common sites where
fractures are seen? S
Cortical Bone - Answers -surrounds bone on outside to form shaft of long bones
Cortical Bone - Answers -i.Dense, compact, hard outer layer of bone designed to
withstand mechanical stresses
1.Skull
2.Long bones of the arms and legs
Trabecular bone - Answers -supportive strength to ends of weight-bearing bone
Trabecular bone - Answers -i.Spongy, less dense, & relatively weaker bone
1.vertebrae
2.Ball of the femur
3.wrist
Trabecular bone has a greater turnover rate, susceptibility to hormone-induced fragility,
and structural fragility
Inadequate Ca intake or low levels of calcium regulating hormones cause withdrawal of
calcium "reserves" in bone to restore any deficit. - Answers -How does a diet poor in
calcium intake lead to osteoporosis?
I.Muscle stimulation and contraction
Ii.Transmission of nerve impulses
Iii.Activation of several enzymes
Iv.Blood clotting - Answers -What functions do calcium form? (4)
A.Weight Bearing exercise stimulates osteogenesis
B.Muscle mass and strength increases occur
C.Lower Limb strength and static and dynamic balance correlation
I.ST should produce some improvement - Answers -16.Why is weight bearing exercise
an attractive strategy to treat this disease? S
