60
What is septic or infective arthritis?
an active local infection on a weakened or compromised joint at the site of the primary infection
61
What are risk factors / etiologies for septic or infective arthritis?
- penetrating trauma (stabbing)
- total joint replacement
- chronic joint damage (RA, age related joint changes)
- diabetes (suppresses immune system, circulation)
- immunosuppression

- substance abuse
- sickle cell disease
- renal failure affects immunity
62
Where is septic or infective arthritis MOST common in the body?
- LE joints, particularly the hip and knee
63
What populations are at an increased risk of septic or infective arthritis?
infants, children, and older adults
64
What is the pathogenesis of septic or infective arthritis?
- microorganism invasion that could be bacterial, viral or fungal
- multiplies rapidly due to
> weakened and compromised joint/health
> moist nature of synovial fluid in the joint
- bacteria activated clotting factors that may lead to thrombosis
65
How soon can we see changes with septic or infective arthritis?
- MASSIVE inflammation or pannus erodes articular cartilage and subchondral bone in a FEW WEEKS (FAST)
66
What will we find in our hx with septic or infective arthritis?
acute and sudden onset of:
- infection S&S
- NWB
67
What will we find in our observation with septic or infective arthritis?
acute and sudden onset of:
- antalgic and asymmetrical gait if they can bear weight at all
68
What will we find in our scan with septic or infective arthritis?
- refusal to move to allow affected joint to be moved- so pain, limited ROM and weaknesses in multiple if not all directions
- possibly pain with compression and relief with distraction depending on whether bone is involved or not
- possible sign of the buttock
69
What will we find with palpation with septic or infective arthritis?
- severe TTP
- abnormal lymph nodes > 2cm diameter, firm, TENDER due to rapid onset of inflammation with infection
- heat
- swelling
70
What kind of referral is septic or infective arthritis?
EMERGENCY referral
71
Why is early dx of septic or infective arthritis critical?
- to avoid permanent joint and bone damage
72
