title: Clinical and epidemiological characteristics of septic arthritis of the hip, 2006 to 2012, a seven-year review.
abstract: OBJECTIVE
  To epidemiologically characterize the population treated at our orthopedic clinic with a diagnosis of septic arthritic of the hip between 2006 and 2012.
  
  
  METHODS
  Fifteen patients diagnosed with septic arthritis of the hip between 2006 and 2012 were retrospectively evaluated. The patients' clinical and epidemiological characteristics were surveyed; a sensitivity profile relating to the microorganisms that caused the infections and the complications relating to the patients' treatment and evolution were identified.
  
  
  RESULTS
  Septic arthritis was more common among males. Most diagnoses were made through positive synovial fluid cultures, after joint drainage was performed using the Smith-Petersen route. Among the comorbidities found, the most prevalent were systemic arterial hypertension, diabetes mellitus, and human immunodeficiency virus. The pathological joint conditions diagnosed prior to joint infection were osteoarthrosis and developmental dysplasia of the hip. The infectious agent most frequently isolated was Staphylococcus aureus. From the clinical and laboratory data investigated, 53.33% of the cases presented with fever, and all except one patient presented with increased measures in inflammation tests. Gram staining was positive in only 26.66% of the synovial fluid samples analyzed. Six patients presented with joint complications after treatment was administered.
  
  
  CONCLUSIONS
  S. aureus is the most common pathogen in acute infections of the hip in our setting. Factors such as clinical comorbidities are associated with septic arthritis of the hip. Because of the relatively small number of patients, given that this is a condition of low prevalence, there was no statistically significant correlation in relation to worse prognosis for the disease.
