Abstract
1. Out of 11,868 children born in one maternity department and examined neonatally three cases (possibly four) of typical dislocation were missed at the first examination but diagnosed and treated with good results within the following few months.
2. One single neonatal examination of the hip is not sufficient. Repeated examinations during the first weeks and months are essential.
3. Treatment with a Frejka pillow is unsatisfactory. The von Rosen splint is preferable.
4. Following the campaign for neonatal diagnosis and early treatment no case of established dislocation has been encountered after the age of six months.
5. Atypical cases present special problems.
