Developmental dysplasia of the hip and ultrasound reading by pediatric orthopedic surgeons: a pilot study.
Ultrasound is an imaging modality utilized for early detection and follow-up of developmental dysplasia of the hip (DDH) in infants. Traditionally, pediatric orthopedic surgeons have relied on radiologists to perform ultrasound examinations and interpret the imaging. Today, however, many orthopedic surgeons are performing and interpreting ultrasound themselves. The purpose of this paper was to evaluate the reliability of pediatric orthopedic surgeons in interpreting ultrasound imaging of infant hips. This was a prospective observational pilot study. After reading an instructional handout about the Graf method of hip ultrasonography, eight pediatric orthopedic surgeons measured 28 hip ultrasound images to determine the alpha angle and percent femoral head coverage. On the basis of cited intraclass correlation coefficient cutoff values, interrater reliability was found to be 'good' for percent femoral head coverage and 'fair' for alpha angle. These findings are equivalent to findings of similar studies using radiologists as examiners. Pediatric orthopedic surgeons can interpret ultrasound exams for diagnosing DDH.
