Following hip aspiration, children with synovial fluid white blood cell values of 25,000 cells/mm3 to 75,000 cells/mm3 were most commonly diagnosed with septic arthritis of the hip, according to study results.
Researchers reviewed the records of 46 pediatric patients who underwent hip aspiration between 2005 and 2012 and had an aspirate white blood cell (WBC) count of 25,000 cells/mm3 to 75,000 cells/mm3, recording demographic data, laboratory values, final diagnosis and treatment details. Using univariate and multivariable logistic regression analyses, the researchers assessed risk factors for septic arthritis of the hip across final diagnostic groups and subgroups with WBC values of less than 50,000 cells/mm3 and of 50,000 cells/mm3 or more.

Results showed final diagnoses of septic arthritis of the hip, Lyme arthritis, transient synovitis, as well as other findings. According to the researchers, patients were more likely to be diagnosed with septic arthritis of the hip if they had a synovial fluid WBC count of 50,000 cells/mm3 or more. The researchers also found septic arthritis of the hip was also represented in 17% of cases with WBC values less than 50,000 cells/mm3. – by Casey Tingle
