title: [Results of conservative treatment of congenital dislocation of the hip--significance of arthrography].
abstract: To evaluate the clinical value of hip arthrography, especially two-directional arthrography, the author compared the treatment results of three different groups, Group A: cases treated without arthrography, Group B: cases treated using anteroposterior arthrography and Group C: cases treated using two-directional arthrography. With Lorenz's method, all three groups achieved about 40% success to G-I, II by Severin's classification. G-III, IV was obtained in Group A, B and C at 50.4%, 19.5% and 2.8%, while cases of open reduction at 3.8%, 37.0% and 55.6%, respectively. By selecting the cases that may obtain G-III, IV with Lorenz's method and by applying open reduction to them, in Group C, reduction was obtained in 93.8% of cases treated with Lorenz's method and 91.7% when cases treated with open reduction were included. Using two-directional arthrography, cases which should not be treated conservatively may be identified to apply open reduction to obtain better overall results.
