Arthritis Flashcards
(45 cards)
osteoarthritis
primarily a degenerative disorder of articular cartilage
not inflammatory
Primary OA formation
slowly with age
Secondary OA formation
typically from predisposing condition, such as traumatic injuries, developmental deformity or comorbidity
OA risk factors
African american men
women post menopause
nutrition hydration
PFC’s from cookware
OA risk factors
genetics
account for at least 50% of cases of OA in hands and hips, small % of knees
OA risk factors
biomechanical
being overweight
overloading knee and hip joints could lead to cartilage breakdown and failure of ligamentous and other structural support
Sports Participation as an OA risk factor
moderate regular running has low, if any, risk
activities that increase the risk demand high intensity, acute, direct joint impact
Prevalence with age and gender (men)
Before 50 years of age men>women
Prevalence with age and gender (women)
After 50 years women are more often affected with hand,foot, and knee, OA
Osteophyte impingement on spinal foramina
Can cause nerve root compression w/ radicular pain, muscle spams, muscle atrophy, and neurologic deficits

Classic signs of inflammation
Cardinal symptom of arthritis
Pain
most frequent complaint
What type of movement restriction is very common with OA
capsular patterns
Rheumatoid Arthritis
chronic, inflammatory autoimmune disease more common in women
2nd-4th decade of life
RA affects the:
synovium/small joints and can also affect multiple tissues
typically PIP and MCP
DIPs are spared
can progress to many other joints
Pannus formation
granulation tissue from synovium spreads over articular cartilage, releases enzymes and inflammatory mediators, destroying the cartilage
Fibrosis
pannus between bone ends become fibrotic, limiting movement
ANkylosis
joint fixation and deformity develops
RA and smoking
faster progression of RA
RA Symptoms
AM stiffness
more C/S involvement
crepitus
joint subluxation
swan neck deformity of the PIP
RA radiographic findings
systemic, inflammatory, swelling, weakening ir periarticular surfaces, symmetric loss of joint space
OA radiographic findings
localized, nonsystemic, instability, osteophyte formation, bony hypertrophy
Anemia may present itself in which form of arthritis?
