Septic arthritis of the pediatric hip: update on diagnosis and treatment

Purpose of review To review the clinical diagnosis, management and natural history of septic arthritis of the hip (SAH) in the pediatric patient, and to highlight new information that may improve the management of these patients. Recent findings The basics of management of possible pediatric SAH have remained largely unchanged for generations. New questions have been raised regarding the role and timing of advanced imaging (MRI) in the evaluation of patients with possible SAH. Published criteria have been derived to guide the need for MRI studies in these patients. Validation of these guidelines continues. Recent reviews have highlighted the possibility of Lyme disease as a potential cause of monoarticular pediatric hip pain. The role of PCR technology in the diagnosis and management of SAH remains unclear at this time. Summary The child with a limp remains a common and urgent clinical concern. There may be expanded roles for MRI and PCR to better diagnose and treat the involved joint itself, as well as any associated nonarticular area of infection. Lyme disease should remain on the list of possible differential diagnoses in this population, particularly in geographic areas where the disease vector is known to be endemic.
