In Greece, despite efforts toward early diagnosis of congenital dislocation of the hip (CDH) during the last 20 years, treatment of 75% of infants so diagnosed has not been begun until they are 2 to 9 months of age, with an average treatment onset age of 4.6 months. Five hundred eighty-seven infants (947 hips) two to nine months of age with typical CDH or subluxation were treated with a specially designed abduction brace. This brace, which has been in use for more than 22 years, proved simple and reliable. The follow-up period ranged from two to 20 years (average, 4.5 years). Excellent results were found in 862 hips (91.0%), good results in 44 hips (4.5%), fair results in 32 hips (3.5%), and poor results in nine hips (1.0%). Changes due to ischemic necrosis were noted in 6.8% of the hips, with severe changes present in 3.0%. The most recent results have improved as a result of greater attention to very gentle and gradual abduction of the hips before the application of the brace and the avoidance of extreme abduction positioning in the brace.
