Ultrasound-Based Screening of Hip Development in Infants at a Tertiary Hospital in Veracruz, México: A Descriptive Cross-Sectional Study

Developmental dysplasia of the hip (DDH) is a major cause of long-term disability if not detected early. Ultrasound has become a valuable screening tool for evaluating hip development in infants. This descriptive cross-sectional study included 210 infants aged 30–100 days screened between April and August 2025 at a tertiary hospital in Veracruz, Mexico. Hip ultrasound was performed using the Graf classification method. Most hips were classified as Graf type I (71.9%), while 28.1% were Graf type IIa. Breech presentation was the only risk factor significantly associated with hip immaturity (p = 0.024). Ultrasound screening identified clinically silent hip immaturity, supporting its value as an early screening tool.
