Validation of the Pediatric Arthritis Ultrasound Scoring System for the Elbow, Wrist, and Finger Joints in Children With Juvenile Idiopathic Arthritis.

ABSTRACT:

Objective

We aimed to validate the Pediatric Arthritis Ultrasound Scoring System (PAUSS) for upper extremity joints in children with juvenile idiopathic arthritis (JIA).

Methods

Children with JIA were evaluated for elbow, wrist, or finger arthritis by clinical examination (CE) and musculoskeletal ultrasound (MSUS) with images scored according to the joint-specific PAUSS. A subset of children received contrast-enhanced magnetic resonance imaging (ceMRI) of the affected joint(s). The performance of the PAUSS as a measure of arthritis activity was compared to CE and ceMRI, using ceMRI as the reference standard.

Results

Seventy-five children contributed 44 elbows, 55 wrists, and 106 fingers for MSUS and 15 elbows, 16 wrists, and 40 fingers for ceMRI. B-mode PAUSS scores f
