Congenital Dislocation of the Hip - Development of frequency, diagnosis and treatment within the last 7 years

Problem: How has the Congenital Dislocation of the Hip (CDH) developed in t he last 7 years concerning frequency, time of diagnosis and therapy? Method: Retrospectiv analysis of hospital reports, ultrasound- and X-ray im ages of children treated with CDH in the University Hospital. Results: From 1. 1. 1991 to 31. 12. 1997 21 children with 28 dislocated hip s were treated. The number of dislocated hips per anno is less than in a fo rmer study. In 17 children the diagnosis was found by ultrasound. The diagn osis was made within the first week of life in 8 children. In 9 dislocated hips, open reduction was neccessary; in 7 of these 9 joints, diagnosis was made in the first days of life. Conclusions: Because of the distinct declination of CDH the "true" congenit al dislocations, in which open reductions were often neccessary, predominat ed.
