Septic arthritis resident survival guide:

Complete diagnostic approach:

Common Presentation

Symptoms in newborns or infants:

  • Cries when infected joint is moved (e.g. diaper change causes crying if hip joint is infected)
  • Fever
  • Inability to move the limb with the infected joint (pseudoparalysis)
  • Irritability

Symptoms in children and adults:

Less common Presentation

 
 
 
 
 
 
 
 

Focused History

  • Intravenous drug use
  • Sexual activity
  • Terminal complement deficiency
  • Dog or cat bite
  • Ingestion of unpasteurized dairy products
  • Nail through shoe
  • Soil exposure/gardening
  • Soil or dust exposure containing decomposed wood

(north-central and southern United States)

  • Southwestern United States, Central and South America

(primary respiratory illness)

  • Cleaning fish tank
 
 
 
 
 
 
 
 

Physical Examination

Appearance of the Patient

Vital Signs

Skin

  • Warmth over the joint

Extremities

Most commonly involves knee > hip > shoulder > ankle.[2] Other joints such as sacroiliac joint (~10%), sternoclavicular or costoclavicular joints may be involved in patient with history of intravenous drug abuse (IVDA), penetrating trauma, animal or human bites and local steroid injections.

  • Swelling of the joint that involved
  • Decreased range of motion such as pseudo paralysis
  • Patient hold the hip in flexed and externally rotated position if SA involving hip.
  • If child, unwillingness to bear weight on the affected joint (antalgic gait)
 
 
 
 
 
 
 
 

Laboratory Workup

 
 
 
 
 
 
 
 

Imaging Study

Plain radiographs of swollen joints

  • Swelling of the joint capsule and soft tissue around the joint
  • Fat pad displacement
  • Joint space widening due to localized edema and effusion.[3][4][5]

Computed tomography (CT)

  • Visualization of joint effusion
  • Soft tissue swelling
  • Para-articular abscesses
  • Joint space widening due to localized edema, bone erosions, foci of osteitis, and scleroses.[6][4]


Magnetic resonance imaging (MRI)

  • Synovial enhancement
  • Perisynovial edema
  • Joint effusion
  • Signal abnormalities in the bone marrow
 
 
 
 
 
 
 
 

Other Investigation

PCR

Arthrocentesis

  • In the presence of joint effusion to differentiate between different causes of arthritis[7]
