Timing of Repeat Ultrasound Examination in Treatment of Stable Developmental Dysplasia of the Hip

“…In line with the Dutch DDH guideline, infants with certain risk factors for DDH (positive family history for DDH or hip osteoarthritis less than 50 y of age or breech position >32 wk of pregnancy) or abnormalities on physical examination (hip abduction <70 degrees or side to side hip abduction difference ≥20 degrees) were referred to the pediatric orthopaedic surgeon at the age of 3 months. 6 In case of premature birth, the referral age was corrected by calculating the chronological age in weeks minus the number of weeks of prematurity. All referred infants were screened with ultrasound imaging by trained radiologists and at presentation at the Máxima MC physically examined and classified according to the Graf classification by one of 3 pediatric orthopaedic surgeons.…”

“… 5 The Dutch youth health care DDH guideline recommends ultrasound screening to be performed at the age of 3 months in infants with certain risk factors for DDH (positive family history of DDH or breech position >32 wk of pregnancy) or abnormalities during physical examination. 6 Once diagnosed with DDH by an orthopaedic surgeon, treatment of choice in the first 6 months of life consists of a dynamic flexion abduction device such as the Pavlik harness. 7 , 8 Pavlik harness treatment is one of the most effective treatment modalities for stable DDH in infants below 6 months of age with a success rate of up to 85%.…”
