“…The NHI rate of 19.4 per 1000 in the present study is similar to that of Bristol, UK (19 per 1000) and Taranaki, New Zealand (32 per 1000), using similar diagnostic criteria 3,10 . Underestimation of current Australian NHI rates can be traced to retrospective analyses that calculate prevalence rates of CDH by adding detected NHI to ‘late detected’ or ‘missed’ CDH, giving the impression that every missed case of NHI becomes a ‘late detected’ or ‘missed’ CDH 6,12,13,25,35 36 .…”

“…Definitions have been either inclusive (dysplasia on ultrasound but clinically stable) or exclusive (omitted on treatment criteria despite possible clinical abnormalities) 6,12 . The only other Australian prospective study (involving 450 newborns) combined retrospective with prospective data and included diagnoses of ‘lax hips’ and ‘tight adductors’ 35 …”

The Epidemiology and Demographics of Hip Dysplasia

2011

The etiology of developmental dysplasia of the hip (DDH) is unknown. There are many insights, however, from epidemiologic/demographic information. A systematic medical literature review regarding DDH was performed. There is a predominance of left-sided (64.0%) and unilateral disease (63.4%). The incidence per 1000 live births ranges from 0.06 in Africans in Africa to 76.1 in Native Americans. There is significant variability in incidence within each racial group by geographic location. The incidence of clinical neonatal hip instability at birth ranges from 0.4 in Africans to 61.7 in Polish Caucasians. Predictors of DDH are breech presentation, positive family history, and gender (female). Children born premature, with low birth weights, or to multifetal pregnancies are somewhat protected from DDH. Certain HLA A, B, and D types demonstrate an increase in DDH. Chromosome 17q21 is strongly associated with DDH. Ligamentous laxity and abnormalities in collagen metabolism, estrogen metabolism, and pregnancy-associated pelvic instability are well-described associations with DDH. Many studies demonstrate an increase of DDH in the winter, both in the northern and southern hemispheres. Swaddling is strongly associated with DDH. Amniocentesis, premature labor, and massive radiation exposure may increase the risk of DDH. Associated conditions are congenital muscular torticollis and congenital foot deformities. The opposite hip is frequently abnormal when using rigorous radiographic assessments. The role of acetabular dysplasia and adult hip osteoarthritis is complex. Archeological studies demonstrate that the epidemiology of DDH may be changing.

“…Stable hips with dysplasia were monitored initially and reassessed according to protocol within two weeks, with treatment escalated to a Pavlik harness if spontaneous improvement not observed. Double nappies were neither encouraged nor discouraged, as there is little evidence supporting its efficacy 17,18 and neither are direct complications reported. Ultimately the decision to nurse infants in double nappies during the "watch and wait" period was at parental discretion.…”
