1. The operative procedure referred to in this paper aims at the removal of all abnormalities of the dislocated hip in a one-stage operation, thus shortening to a minimum the time necessary for treatment.
2. The most favorable age for this procedure ranges from three to five years; of 111 children in this age group, ninety-four had excellent and good results, twelve had fair, and only five had poor results.
3. Six is the maximum age limit at which it is still possible to expect a satisfactory result.
4. Whereas the majority of failures in the group of children between the ages of three to five years may be attributed to faulty operative technique, the bulk of failures in children over six are due to vascular changes which develop despite correct operative technique.
6. The follow-up period (two to four years) is too short to allow a definite conclusion to be drawn. This paper must then be regarded as a preliminary report.
