Open reduction of CDH before one year of age: 69 hips followed for 13 (10–19) years

Abstract

50 children (69 hips) had open reduction of congenital dislocation of the hip (CDH) at the age of 7 (2–12) months. 4 hips had a poor result from severe necrosis of the femoral head. Another 5 hips with less severe necrosis had a fair result. 7 of the 9 hips with avascular necrosis were below the age of 6 months at the time of operation. 13 hips (9 children) required complementary operations to establish congruous reduction of the hip. The follow-up period was 13 (10–19) years, and the results were successful in 53 hips. No difference was found in the unilaterally and bilaterally operated on hips. Anteversion corrected itself in due time in most of the hips, and coxa magna had disappeared in hips that had reached maturity. Good hips remained good and poor hips became progressively worse.
