Taking all grades of hip dysplasia into account (Graf types II, III and IV), there was no statistical difference in the incidence of dysplasia between the groups (elective section 8.4%, emergency section 8.1% and vaginal delivery 7.0%). However, when cases with Graf type II dysplasia, which may represent physiological immaturity, were excluded, the rate of type III and IV hips, which we consider to be clinically relevant, increased in the vaginally delivered group (4.7%) compared with the elective section group (1.1%), with a relative risk of approximately 1:4 (95% confidence interval 1.03 to 15.91). No difference was observed between the emergency and elective section groups, or between the emergency section and vaginally delivered groups. <\/jats:p><jats:p> This study supports previous published work, with the added value that the diagnoses were all confirmed by ultrasound. <\/jats:p>","DOI":"10.1302\/0301-620x.92b12.24960","type":"journal-article","created":{"date-parts":[[2010,12,1]],"date-time":"2010-12-01T00:50:10Z","timestamp":1291164610000},"page":"1695-1699","source":"Crossref","is-referenced-by-count":21,"title":["The relationship between mode of delivery and developmental dysplasia of the hip in breech infants"],"prefix":"10.1302","volume":"92-B","author":[{"given":"A.
