What this trial studies

This observational study aims to gather normative data on ultrasound radiographic parameters for evaluating hip dysplasia in infants born between 32 and 46 weeks of gestational age. Conducted at Community Regional Medical Center, the study involves obtaining consent from legally authorized representatives of newborns and performing non-invasive hip ultrasounds during their hospital stay. The collected data will be used to develop a growth chart that includes standard deviations, aiding in the treatment of suspected hip dysplasia. Follow-up ultrasounds will be scheduled weekly until the newborn's hips meet normal morphology criteria or they reach six weeks of corrected age.

Who should consider this trial

Good fit: Ideal candidates include newborns born at Community Regional Medical Center, both term and pre-mature, who are over 32 weeks gestational age.

Not a fit: Patients with known neuromuscular or genetic conditions predisposing them to hip dysplasia, or those who cannot follow up, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a standardized growth chart for assessing hip development in newborns, improving early detection and treatment of hip dysplasia.

How similar studies have performed: While similar studies have explored hip dysplasia, this approach of developing a normative growth chart using ultrasound data in this specific age group is relatively novel.
