先天性股関節脱臼の早期外来治療 (特に大腿骨骨頭側方化の問題について)

抄録

It is clear, as many authors say, that the results of early treatment of congenitally dislocated hip with Pavlik's bandage are superior to those with classical methods. Resultant lateral displacement or subluxation of femoral head after this treatment, however, is seen considerably. We assume the main causative factor of the lateral displacement must be passive stretch of tight iliopsoas muscle resulting from relaxinng the band in the course of the treatment. We think that the best way for the prevention of this complication is to lengthen the tight iliopsoas muscle gradually by slacking the band. After 2 to 3 weeks from spontenuous reduction the band is begun to slack gradually from so-called ‘frog’ position to 45 degrees' flexion and 25 degrees' abduction position, and the latter position is kept until satisfactory growing of acetabulum is aquired.
Although we get relatively good results, further observation will be required for the conclusion in our methode because of shortness of observation time.
