Q

how does osteoarthritis develop?

A

the articular cartilage is damaged and eroded through stress, and the tissue damage causes the release of enzymes that accelerate the disintegration of the cartilage; the bone eventually is exposed, causing cysts, osteophytes, or new bone spurs to develop and break off into the synovial cavity; this causes the joint space to narrow and for inflammation to develop

Q

why is osteoarthritis a cycle?

A

because once the cartilage is damaged, joint alignment or the frictionless surface of the cartilage is lost, and then the mechanical stress is applied to other parts of the joint and to other joints

Q

how does rheumatoid arthritis develop?

A

an abnormal immune response causes inflammation of the synovial membrane, along with vasodilation, increased permeability, and the formation of exudate, causing red, swollen and painful joints; often begins in the small joints in the fingers, followed by other joints like the wrists, eblows, knees

Q

panus formation

A

granulation tissue from the synovium spreads over the articular cartilage; this tissue which is called pannus releases enzymes and inflammatory mediators that destroy the cartilage

Q

cartilage erosion

A

Q

how is surgery used for rheumatoid arthritis?

can remove pannus, replace damaged tendons, reduce contractures, or replace joints; more common in the hands

aka septic arthritis; usually develops in a single joint and the joint is red, swollen, painful, with decreased ROM; is caused by a bacteria

39
Q

causes of infectious arthritis

A

bacterial infection from for example gonococcus or staphylococcus; can also develop from osteomyelitis infections

40
Q

how is infectious arthritis treated?

A

immediate aggressive antimicrobials treatment

41
Q

lyme disease

A

is caused by a spirochete and transmitted by ticks; a migratory arthritis and rash develop, in which the knee and other large joints are affected

A

is an autoimmune form of arthritis that is accompanied by the skin disease psoriasis; there are five forms

43
Q

five forms of psoriatic arthritis

A

symmetric, asymmetric, distal interphalangeal dominant, spondylitis, and arthritis mutilans

44
Q

causes of psoriatic arthritis

A

unknown but is a combination of genetic and environmental factors

45
Q

symptoms for psoriatic arthritis

A

swollen, tender joints, morning stiffness, swollen fingers and toes, painful muscles and tendons, scaly skin patches, flaky scalp, fatigue, nail pitting, seperation of the nail from the nail bed, eye redness, and eye pain

46
Q

treatment for psoriatic arthritis

A

NSAIDs, DMARDs, biologics, steroids, immunosuppressants, topical treatments, and light therapy

47
Q

gouty arthritis

A

is a joint disease the results from deposits of uric acid and urate crystals in the joint that then cause an acute inflammatory response usually in a single joint

48
Q

who is gouty arthritis common in?

A

men > 40

49
Q

uric acid

A

is a waste productnof purine metabolism that is normally excreted through the kidneys

50
Q

hyperuricemia

A

may develop if renal excretion is not adequate or due to a metabolic abnormality

51
Q

what precipitates an attack of gout?

A

a sudden increase in serum uric acid levels

52
Q

acute gout inflammation episode

A

usually a single joint is affected and the articular cartilage is damaged, causing redness, swelling, and pain of the joint

53
Q

tophus

A

is a large, hard nodule consisting of urate crystals that have been precipitated in soft tissue or bone, causing a local inflammatory reaction

54
Q

where do tophus develop?

A

at the joint bursae, the extensor surfaces of the forearm, or the pinnae of the ear

55
Q

treatment for gouty arthritis

A

reducing serum uric acid levels by drugs and dietary changes; increasing fluid and increasing the pH will cause more uric acid excretion; colchicine is used during an acute episode and allopurinol is used as a preventative measure

56
Q

what is the risk of uric acid in the blood?

A

kidney stones may develop

57
Q

ankylosing spondylitis

A

is a chronic progressive inflammatory conditions that affects the sacroiliac joints, intervertebral spaces, and costovertebral joints of the axial skeleton

58
Q

risk population for ankylosing spondylitis

A

more common in men and ages 20-30

59
Q

causes of ankylosing spondylitis

A

it is an autoimmune disorder with a genetic basis and the presence of the HLA-B27 antigen

60
Q

what happens in ankylosing spondylitis?

A

the vertebral joints become inflamed, followed by fibrosis and calcification or fusion of the joint, and this results in ankylosis of fixation of the joints; inflammation develops in the lower back, followed by kyphosis; osteoporosis and lung expansion difficulties may develop as a result

61
Q

signs of ankylosing spondylitis?

A

low back pain, morning stiffness, pain that radiates to the legs, rigid spine, systemic signs like fatigue, fever, and weight loss, and uveitis

62
Q

treatment for ankylosing spondylitis

A

pain relief and maintenance of mobility, along with sleeping supine, exercising, and antiinflammatory drugs

63
Q

bursitis

A

is an inflammation of the bursae associated with bones, muscles, tendons, and ligaments

64
Q

bursae

A

small, fluid-filled sacs that act as cushions at or near the structures of joints

65
Q

causes of bursitis

A

repetitive motions that physically irritate the bursae, ex. washing floors on hands and knees and throwing a baseball

66
Q

diagnosis of bursitis

A

physical examination (looks for red, swollen, achy and stiff joints) and MRI

67
Q

treatment for bursitis

A

rest, cold compress, anti inflammatory drugs, PT, and antibiotics (when infection is the cause)

68
Q

synovitis

A

inflammation of the synovial membrane lining the joint; movement of the joint is painful and the joint is swollen, red, and warm

69
Q

how is synovitis diagnosed?

A

analyzing the synovial fluid for signs of infection or crystals

70
Q

tendonitis

A

is the irritation or inflammation of the tendon, often characterized by a dull ache at the site of tendon attachment, tenderness, and mild swelling
