What are the five types of connective tissue?
Bones, cartilage, ligaments, tendons, and fascia
What two structures absorb energy from impact?
Bones and cartilage
What are the three bone cells and their functions?
- Osteoblasts - bone forming cells
- Osteocytes - mature bone cells
- Osteoclasts - bone remodelling
What does rheumatoid factor, creatine kinase, and ESR blood studies indicate?
- Rheumatoid factor - Measures presence of autoantibody in serum
- CK - Measures serum levels of an enzyme found in skeletal muscle, heart muscle, and brain (Not a specific test that indicates area that has been effected, it is a general test)
- ESR - Measures non-specific index of inflammation
What does CRP, uric acid, calcium, and phosphorus blood studies indicate?
- CRP - Used to diagnosis inflammatory disease (Not a specific marker, just indicates inflammation is present)
- Uric acid - End product of purine metabolism
- Calcium - Mineral needed to build and maintain strong bones
- Phosphorus - Mineral needed to build and maintain strong bones
Does arthritis affect men or women more?
Women
Define osteoarthritis
Slow, progressive, unilaterl, non-inflammatory disorder that affects diarthrodial joints (synovial)
What types of joints does osteoarthritis and rheumatoid arthritis affect?
Diarthrodial joints
What is osteoarthritis the gradual loss of?
Cartilage in the joints
What age can osteoarthritis begin and the average age?
May begin between 20-30, but average is 40
Does osteoarthritis have a known cause?
May have a cause of a known event/condition or no known cause
What six factors increase the risk of osteoarthritis?
- Decreased estrogen may play a part
- obesity
- regular moderate exercise
- sports with quick stops and pivots
- occupations with kneeling and stooping
- genetic and metabolic factors
How does the cartilage change in osteoarthritis?
Becomes yellow, dull, granular, softer, less elastic, and less able to take impact/move
Cartilage cannot repair fast enough
Cartilage is cracked and worn
How do the joint edges become with osteoarthritis?
Central cartilage is thinner, joint edges become thicker; making the joints uneven
Is osteoarthritis an inflammatory or non-inflammatory condition?
Non-inflammatory
What are the 6 clinical manifestations of osteoarthritis?
- Crepitation
- Pain that increases with joint use
- Pain relieved with rest (early stages)
- Sleep disrupted by pain (late stages)
- Pain leads to disability and loss of function
- Referred pain
Would someone with osteoarthritis spend more time standing or sitting as a result of pain?
Spend more time standing due to joint stiffness after rest/static positions
Would someone with osteoarthritis feel joint stiffness relief in the morning?
Yes, usually within 30 minutes
Is osteoarthritis unilateral or bilateral?
Unilateral
What joints does osteoarthritis commonly effect?
Fingers, thumb, weight bearing joints (hips or knees), foot, cervical, and lower lumbar spine
Heberden’s and Bouchard’s nodes are related to what disease?
Osteoarthritis
What is the difference between Heberden’s and Bouchard’s nodes?
Heberden’s - exist on the first joint (distal)
Bouchard’s - exist on the second joint
How do Heberden’s and Bouchard’s nodes present?
Red, swollen, and tender
Do Heberden’s and Bouchard’s nodes cause dysfunction?
No, not usually
