5. Arthritis arthr/o: joints itis: inflammation
Define the term based on the meaning of its parts.
arthr/o: joints itis: inflammation
Inflammation of one or more joints, very painful, different types 5

6. Arthritis Osteoarthritis
Degenerative, occurs with aging, joints become large and painful
Treated with medications 6

7. Arthritis Rheumatoid arthritis
Chronic, autoimmune disease, joint becomes swollen and painful, joint deformities are common 7

8. Arthritis Arthritis Compare rheumatoid arthritis and osteoarthritis.
Osteo - occurs with aging
Rheumatoid - autoimmune 8

9. Gout Uric acid deposited in joint cavity mostly the great toe
prevalent in men
very painful
Gout is treated with diet and medication 9

10. Osteoporosis Break down the word: Oste/o : bone por/ous : having holes
- osis : condition
What household object does osteoporosis remind you of? Sponge or swiss cheese 10

11. Osteoporosis Osteoporosis affected 80% of women are
Involves loss of bone mass, calcium and phosphorus leading to thin porous (spongy) bones prone to fracture 11

12. Osteoporosis Treatment:
Prevented by dietary calcium and Vitamin D intake 12

13. Rickets Found in children with poor diet (most often in poverty)
Normal legs
Found in children with poor diet (most often in poverty)
Caused by a lack of Vitamin D
Bones become soft (osteomalacia)
Bones brend and break easily 13

14. Rickets
Normal legs
Treatment
Medications that include calcium, vitamin D and sunshine
Difficulty walking due to malformed long bones in legs
Is this a health concern in the U.S.?
Yes, particularly in poverty areas 14

15. Abnormal Spinal Curvatures
Kyphosis Lordosis Scoliosis
Hunchback Swayback Internal
Curve in thoracic spine Curve in lumbar spine S curve in spine

16. Trauma
Trauma
Dislocation: bone displaced from proper position in joint
Fractures: any break in bone 16

17. Dislocation Dislocation Subluxation
Bone displaced from normal position
Subluxation
A partial dislocation 17

18. Skeletal System Trauma
Fracture: any break in bone - confirmed by X- Ray 18

19. Trauma: Fractures Fractures:
Many types of fractures treated differently 19

20. Skeletal System Trauma
Fractures
Closed or simple
Broken bones do not break skin
Usually requires a cast 20

21. Trauma: Fractures Fractures Open or compound Broken bones pierce skin
Can lead to infection
Usually needs to be fixed by open reduction and internal fixation - this involves surgery, using pins and screws to secure the break 21

22. Skeletal System Trauma
Fractures
Comminuted
Splintered or broken into many pieces 22

23. Trauma: Fractures Fractures Greenstick Very common in children
Bone bent and splintered but never completely separates 23

24. Trauma: Fracture Fracture sites related to osteoporosis
Why are these common fracture site for older adults?
Brace for fall land on side humpback 24

25. Trauma: Sprain Sprain: Caused by sudden or unusual motion
Ligaments are torn or damaged
Treat with RICE: rest/ice/compression/elevation 25

26. Trauma: Strain Strain:
Caused by overstretching of tendons or tearing of muscle, the muscle can bleed (Bruise)
Treat with RICE:
Rest
Ice for 48 hours
Compression: wrap are of injury
Elevation the injury 26
