We studied 195 hips of 171 patients treated with a Pavlik harness for congenital dislocation of the hip joint between 1970 and 1992 at Kyushu University. Patients were classified into two groups: 148 hips in the reduction group, and 47 hips in the non-reduction group. We compared these two groups in regard to sex, affected side, family history, fetal presentation, birth weight, and fetal age. The results were then classified by Severin's criteria for patients aged over six years in the reduced group.The rate of reduction was 81% in those patients in whom treatment was begun between birth and the age of six months, and 51% between 7 and 12 months. Yamamuro's "a" distance was 8.2mm on average in the reduction group, and 4.6mm in the non-reduction group. The difference of "OT" distance was 2.4mm in the former, and 5.6mm in the latter. There were significant differences between the two groups in regard to both of these distances.
