Osteoporosis

Question 1

What is bone composed of?

Answer 1

Collagen fibres, calcium, phosphate

Question 2

What are the 2 types of bone in the body?

Answer 2

Trabecular and cortical

Question 3

Does the skeleton naturally remodel itself?

Answer 3

Yes

Question 4

What and where is cortical?

Answer 4

Compact, outer layer of bone, mostly in long shaft of bone, 80% of skeleton

Question 5

What and where is trabecular?

Answer 5

Cancellous, spongy material(central mesh work of bone) 20% of skeleton, more brittle is more likely to fracture

Question 6

What is the order of the bone from outside in

Answer 6

Blood vessels, periosteum(membrane), cortical, marrow, medullary cavity, trabecular

Question 7

What is bone turnover

Answer 7

Surface event

Question 8

Define strength of bone measured by

Answer 8

Trabecular vs. Cortical

Question 9

How does bone remodel itself

Answer 9

Gradual process(remodelling) involves a repeating cycle of breaking down existing bone bit by bit

Question 10

What is mineralization

Answer 10

Laying down new cells

Question 11

Define remodelling

Answer 11

Strength and integrity by replacing old bone, mineral homeostasis

Question 12

What happens when your body lacks calcium

Answer 12

Calcium needed for heart rate muscle contraction blood pressure when calcium drops steals from bones and you get osteoporosis

Question 13

Who’s going to get 100% on anatomy Friday?

Answer 13

You are!

Question 14

What is osteoporosis

Answer 14

Metabolic bone disorder, happens when rate of bone reabsorption accelerates while formation flows, causes loss of mass, bone looses calcium&phosphate bc of disease( in picture bone cells look swollen, darker, less cells)

Question 15

Why is osteoporosis worse during metapause

Answer 15

Decrease in est an prog decrease in circulatory system, bones experience greater numbers of remodelling= higher risk for age related losses in mass

Question 16

What is the most common osteoporosis spinal fracture?

Answer 16

Vertebral compression fractures(VCF)

Question 17

What are vertebral fractures from?

Answer 17

NOT connected with severe trauma, from very low impact pressures and movements an bones are so brittle( compression fracture common)

Question 18

Pain associated with VCFs…

Answer 18

Severe and local to site( typically mid thoracic, lower “”, and lumbar spine( pain increases with prolonged sitting standing etc)

Question 19

Signs and Symptoms of VCF’s…

Answer 19

Loss of height, bone loss, muscle spasm lower back, burning, back pain, fractures

Question 20

What are the key muscles for VCF

Answer 20

Trunk extensors, hip abduction, gastrosoleus

Question 21

Physical Examinations look at..

Answer 21

Balance, gait, sensation, bone mineral density testing( BMD)**(best way)

Question 22

What’s is BMD

Answer 22

Bone mineral density testing measures mineral content of bone in grams per square cm

Question 23

Issues with VCF

Answer 23

Self care, leisure, productivity, sensorimotor, psychosocial

Question 24

No cure for osteoporosis ( prevention& early intervention important)( work on improving quality of life, preventing, manage symptoms, increase bone mass)

Answer 24

Good job!

Question 25

Osteoporosis devices

Answer 25

Balance balls, exercises, spinal corsets, aquatic exercises

Question 26

Joint protection for osteoporosis

Answer 26

Even stress an weight on joints, avoid static holding position for long times, avoid lifting, take rest brakes
