Sound Conduction of Infant Hips

Pilot Study on the Evaluation of Sound Conduction of Healthy Infant Hips and Those With Developmental Dysplasia of the Hip (DDH)

The objective of this study is to collect data that will be used to later design a method for the early diagnosis of diagnosis of developmental dysplasia of the hip (DDH).

This will be a prospective study using an acoustic listening technique in combination with a standard clinical examination of DDH. For both the clinical cases and healthy children that are enrolled, that all subjects will have an ultrasound completed for comparison to the use of the studied tuning fork method. The gold standard is POCUS (point of care ultrasound as performed by the pediatric orthopedic surgeon). Collected data will be compared to POCUS as performed by an expert and this is standard of care. Healthy subjects will be referred for evaluation and found to be healthy on subsequent US.

Infants will be studied for 15 min using an electronic "tuning fork" to transmit sound through the hip from a point on the skin while transmitted sounds FDA-approved stethoscope

Descriptive statistics will be used to evaluate sound wave characteristics in infants with healthy hips. Inferential statistics will be used to compare the relationship between soundwave characteristics and diagnostic findings
