Definition: A benign, self-limited inflammation of the hip joint; Symptoms mimic septic arthritis (atraumatic, fever, inability to bear weight/new limp and acute onset of pain) Treatment: anti-inflammatories and follow-up; Kocher Criteria (Kocher 1999, Kocher 2004) Septic arthritis, also known as joint infection or infectious arthritis, is the invasion of a joint by an infectious agent resulting in joint inflammation. While many algorithms exist to assist in this clinical diagnosis, there is no single agreed upon set of predictive criteria. 2) Sed rate greater than 40mm/hr. 5 degrees C) was the best predictor of septic arthritis followed by an elevated C-reactive protein level (levels >20mg/L), an elevated erythrocyte sedimentation rate, refusal to bear weight, and an elevated serum white blood-cell count. Cortical window in the region of affected bone. Although the Kocher criteria was developed for evaluating the pediatric hip, data from the present study suggest that these criteria are useful for differentiating Lyme from septic arthritis when the ankle and multiple joints are involved. Kocher Criteria non- weight bearing (4,5) Kocher et al. 8°F) No. 6% chance of having septic arthritis Also here is a GREAT presentation on determining the etiology of a limp, particularly septic arthritis vs transient or toxic synovitis. al. septic arthritis, based on four independent predictors (the Kocher Criteria): a history of fever > 38. The Kocher criteria are established clinical parameters that predict hip septic arthritis (SA) with a 93% or greater positive-predictive value when 3 or 4 variables are present. Components of the Kocher criteria are: [1] Walking or weight bearing inability, [2] Fever >38. The medical records of 282 children with signs of Septic arthritis typically causes extreme discomfort and difficulty using the affected joint. Other joints: swelling, warmth, redness and tenderness at affected joint. In a child with hip pain, presence of the following 4 criteria increases the likelihood of septic arthritis: fever >38. Definitive diagnosis requires an invasive procedure, thus making clinical evaluation and suspicion extremely important. 9 Depending on the number of cri- Method developed by Kocher in 1999 to help differentiate septic arthritis from transient synovitis for children presenting with a hip effusion on ultrasound: History of fever; WBC > 12,000; ESR > 40; Refusal to bear weight 0/4 Criteria met = < 0. Conversely, some patients with septic arthritis may have WBC counts < 50,000, and the immunosuppressed patient may mount little to no leukocytic response at all. RESULTS The same four independent predictors of septic arthritis of the hip (a history of fever, non-weight-bearing, an erythrocyte sedimentation rate of 40 mm/hr, and a serum white blood-cell count of >12,000 cells/mm(3) (>12. The most common muscle affected was obturator internus (65. cut-off for the diagnosis of septic arthritis, though gout and pseudogout are known to result in similar WBC counts [23]. Usually only one joint involved. Kocher’s clinical criteria is, at best, only OK at helping to differentiate TS from SA. Differentiating between septic arthritis and transient synovitis of the hip in children: an evidence-based clinical prediction algorithm.

Differentiating septic arthritis from transient synovitis in pediatric patients is aided by the use of Kocher criteria which have excellent sensitivity but lack specificity. A point is awarded for the presence of each criteria and is associated with Kocher assessed children who underwent joint aspiration for suspected septic arthritis. Thus, the Kocher criteria are used to help determine the likelihood of septic arthritis versus transient synovitis. Antibiotic Treatment of Lyme Arthritis Septic arthritis is an orthopaedic emergency which requires timely management to prevent joint destruction and poor outcome. Two predictors present: 40% risk of septic hip; Three predictors present: 93% risk of septic hip; All 4 factors present strongly suggests infection (60-98% likelihood of septic hip) Modifications.

In the absence of peripheral leukopenia or prosthetic joint replacement, synovial fluid white cell count with WBC > 50,000 is considered diagnostic for septic arthritis, however lower counts may still indicate infection ; gram stains only identifies infective organism 1/3 of time; glucose less than 60% of serum level; negative "string" sign. Mininder S. WBC Collected data included the initial criteria described by Kocher and colleagues: history of fever, non-weight-bearing, erythrocyte sedimentation rate, and serum WBC as well as a recently modified criterion: C-reactive protein. Heizer, a physician assistant in the department of pediatrics at the University of Colorado at Denver. Kocher et al (1-3) in several studies proposed criteria (named Kocher’s criteria) to help differentiate between them. Kocher, M.

The Kocher criteria were derived to identify the variables that are important in distinguishing between septic arthritis (SA) and transient synovitis (TS). In the appropriate clinical setting, patients who fall on either probability extreme (0 criteria or 4 criteria) can be readily ruled in or out for SA. When septic arthritis is a differential diagnosis, which imaging modalities are routinely requested? Plain film radiographs of the joint √ Ultrasound √ (4,5) Kocher et al.

Septic arthritis is already studied, but there is under reporting of neonatal septic arthritis from under developed regions. Abstract. * Required. In a child with a hip joint effusion, the presence of each of the following clinical Based on the criteria, if a doctor is concerned for septic arthritis, further tests are ordered, like an ultrasound of the hip to look for increased fluid (an infection will cause the hip to be inflamed and swollen), or an MRI (to look for an infection in the bone surrounding the joint, aka osteomyelitis). They were originally developed for the hip. Subsequent authors evaluating the same criteria produced conflicting results. B: Range of movement <50% normal.
