Abstract

|
Septic arthritis of the elbow is a rare, but serious disorder in neonates. However, neonates often present with few systemic signs other than irritability or poor feeding. When the clinical findings are minimal or absent, joint aspiration gives us helpful information in making a diagnosis. Although many clinicians rely on its result, we experienced a case of early clotted joint effusion, which resulted negative joint aspiration in a neonate with septic elbow arthritis. Ultrasonography helped us to make an early decision to perform surgical intervention as showing different echogenicity of intracapsular portion from generally presented in septic effusion. Presenting case shows that ultrasonography can be an excellent second step examination of neonatal elbow presenting atypical clinical findings of septic arthritis
