The Limping Child

Background

Most children begin walking between 12 and 18 months. Their initial gait starts broad-based, often with short asymmetric steps. At faster speeds, they often develop foot slapping and asymmetric arm swinging. By ages 3-5 years-old, children start to walk with more fluidity and symmetric strides. By ages 5-7 years-old, their gait begins to resemble the same pattern as an adult.

5 Minute Journal: Kocher Criteria for Septic Arthritis

This week’s 5-minute Journal Article discussion covered

“Validation of a Clinical Prediction Rule for the Differentiation Between Septic Arthritis and Transient Synovitis of the Hip in Children” by Kocher et al.

 

Why is it important to differentiate between septic arthritis and transient synovitis in pediatric patients? Because both diseases can present similarly with acute onset of pain, fever, limp or inability to bear weight and patients holding their hip in the flexed, abducted, externally rotated (FABER) position. The difference is transient synovitis is exactly that, transient, while septic arthritis can lead to permanent joint damage and disability if not treated aggressively with surgical intervention and IV antibiotics.
