age, post menopause, hormone disorders, deficits of Ca or vitamin D or protein, cigarette smoking, small and light bone structure, and excess caffeine

44
Q

What is osteoarthritis?

A

Progressive degeneration and inflammation of joints that gradually wears away cartilage surface exposing bone; inflammation mediators and cytokines degrade cartilage over a period of years

45
Q

Risk factors of OA

A

age, obesity, and hx of sports or previous joint injury

46
Q

Sx of OA

A

osteophytes, pain relieved with rest and worsens over time, stiff joints, limited ROM, burning sensation in joint, can be unilateral, heberden’s node

47
Q

What is rickets?

A

diseases seen in children because of failure of osteoid calcification resulting in “soft tissue”

48
Q

Causes of rickets

A

vitamin D deficiency, hypophosphatemia, lack of milk and sunlight

49
Q

Sx of rickets

A

bowing of femur, sternum protrudes, widening of growth plates, thoracic asymmetry, fontanels do not close

50
Q

What is osteomalacia?

A

a disorder seen in adults due to calcium malabsorption caused by vitamin D

51
Q

Causes of osteomalacia

A

lack of sunlight, renal disorders, cancer, malabsorption, and lack of vitamin D intake

52
Q

What is degenerative disk disease?

A

intervertebral disk flattens in the cervical or lumbar areas. with age disks become rigid and lose elasticity and collapse

53
Q

Risk factors of DDD

A

heavy lifting, obesity, twisting trauma, poor physical condition, family hx

54
Q

Sx of DDD

A

back pain, osteophyte formation, pain radiating down the back of the leg or arm, numbness in extremity

55
Q

What is osteomyelitis?

A

infection and inflammation of a bone by bacteria

56
Q

What is the infection processes of osteomyelitis?

A

contiguous spread- invasion via a wound or puncture
hematogenous spread- invasion via blood stream

57
Q

What is reactive arthritis?

A

an autoimmune reaction in one or more joints caused by bacterial infection in another part of the body

58
Q

What is the etiology of osteomyelitis?

A

staph aureus

59
Q

What is chronic myelitis?

A

untreated or under-treated infection of the bone that lasts more than 6-8 weeks and becomes necrotic susceptible to gangrene

60
Q

Pathophysiology of osteomyelitis

A

bacteria invades the bone tissue and causes abscesses to form and deprive blood supply to the bone. the bone then becomes necrotic an is at risk for gangrene

61
Q

Sx of osteomyelitis

A

systemic: fever, malaise, chills
local: erythema, heat, edema, pain, tenderness
post op: drainage from incision and delayed healing
