Neonatal screening results implied a large number of subjects with a IIa hip, according to Graf\u2019s system; as these subjects require follow-up, the cost of this type of screening is high. Ultrasound findings were normal at 69 days of life in 88% and 75% of subjects, respectively, with unilateral and bilateral type IIa hip.<\/jats:p><jats:p>Conclusion.\u2003This study evaluated various
