“…The sex distribution, side affected, and the incidence of breech presentation are in accordance with the results of other neonatal series (Palmeri 1961, Hirsch & Scheller 1970, Lauritzen 1971, Huttova et al 1972, Ritter 1973, Bjerkreim 1974, Ackermann et aI. 1974, Artz et aI.…”

“…In Australia/New Zealand, it is 3.4 and 8.5 in Auckland, New Zealand [191], 6.6 in Western Australia [192], 6.7 in Sydney, Australia [193], and 19.4 in Victoria, Australia [194]. In North America, it is 1.4 in Iowa City [196], 5.2 in Oklahoma City [167], 8.6 in Salt Lake City [195], 9.2 in Indianapolis, Indiana [198], 5.7 [207] and 9.9 in Vancouver, British Columbia [197], and 15.3 in New York City [168]. The average weighted incidence for all Caucasians is 10.8 (6.0 in Australia/New Zealand to 23.2 in Western Europe).…”

The Epidemiology and Demographics of Hip Dysplasia

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.

“…In large series, the frequency of BP deliveries is about 3%. The frequency of BP among infants with CHD has been reported as 15-30070 (1,2,3). It has been postulated that mechanical stress on the hips in babies born per vaginam in BP is one of the major causes of CHD (2).…”

The purpose of this study was to investigate whether the mode of delivery for fetuses in breech presentation in any way influenced the frequency of congenital hip dislocation. In 13,559 singleton births 583 fetuses were in breech position, and the cesarean section rate was 39.1%. Eighty-three infants were born with congenital hip dislocation, 11 of whom had been in breech position. Of these 11, cesarean section was required in 5 cases. There was no difference in frequency of congenital hip dislocation between fetuses in breech presentation delivered by cesarean section vs. by the vaginal route. The frequency of breech presentation in congenital hip dislocation was 13.3%. Including 7 external versions, the rate was 21.7%. Female to male ratio was 4:1. The frequency of congenital hip dislocations in infants born in vertex presentation was 5.5 per mille and for infants born in breech presentation it was 18.9 per mille.
