Physical Exam
General
Use caretaker to console patient for better exam |
- Vital signs: fever, hypotension, tachycardia, tachypnea
- Pulses and cording of vasculature
- Rash
- Presence of trauma
|
Musculoskeletal |
- Presence of joint effusion(s) — These findings are more suggestive of septic arthritis, reference Septic Arthritis Pathway.
- Swelling, erythema, warmth
- Tenderness to palpation
- Micromotion tenderness (inability to tolerate < 10° of motion) — These findings are more suggestive of septic arthritis, reference Septic Arthritis Pathway.
|
Ambulation or Axial Loading |
- Limp (for hip or leg joint) or preference to remain supine (for vertebral involvement/discitis)
- Refusal or inability to bear weight
|
Likely Absence |
