The Otto Aufranc Award Paper. Infant hip screening.

1. Results of examinations of 10,170 newborns over a 5-year period yielded a rate of 3 to 4 per 1000 with dislocatable or dislocated hips. For whites the ratio is 6.2 per 1000, for blacks 0.4 per 1000. The subluxable rate varied widely from year to year. 2. One baby with late-diagnosed CDH returned, giving a false negative rate of 1 per 10,000. 3. Subluxable hips do not appear to become late-diagnosed acetabular dysplasia. 4. Pediatricians appear to have had deficient training in infant hip screening. 5. Physician extenders are recommended to accomplish more effective hip screening in this country. 6. The Pavlik harness was very effective in the treatment of dislocatable or dislocated hips in newborns.
