Septic arthritis in children

Abstract

Background: Septic arthritis in children is an orthopaedic emergency that has serious consequences if not diagnosed promptly and treated effectively. The presenting symptoms include pain, non-weight bearing and fever. Inflammatory markers are raised and ultra-sonography demonstrates a joint effusion.

Objective: The purpose of this article is to provide an overview of septic arthritis in children.

Discussion: Definitive treatment involves surgical drainage and lavage of the joint, followed by high-dose, empirical, intravenous (IV) antibiotics. Treatment is tailored to the causative organism, if this is identified. For an uncomplicated case of septic arthritis, 2 days of IV antibiotics followed by a 3-week course of oral antibiotics is usually sufficient. Long-term follow-up is necessary to monitor for sequelae of septic arthritis, including cartilage damage, growth disturbance and avascular necrosis of the femoral head.
