Of the 7,827 babies born in Sheffield between March 1989 and August 1991, a total of 114 (1.4%) who had either clinical abnormality of the hip or high-risk factors for congenital dislocation of the hip (CDH) were examined by ultrasound at birth and at regular intervals. Dynamic ultrasound assessment of both hips was done to diagnose instability and to monitor the treatment. Abnormal findings were recorded in 55 babies at the first visit, and 31 of these subsequently required treatment with the Pavlik harness (3.9 per 1,000). Only one case of late CDH has been seen among the babies who were not examined by ultrasound. There were no cases of avascular necrosis in our series. Dynamic ultrasound examination of high-risk infants' hips is a reliable method of screening for CDH. Monitoring of hips treated with the Pavlik harness, by dynamic ultrasound examination, can identify failure to obtain a concentric reduction, and in such cases, splintage can be abandoned in favour of other modes of treatment. It can, therefore, reduce the chances of overtreatment and its associated complications.
