I made a statistical survey of 209 cases after the reposition of the congenital dislocation of hip joint in recent 3 years.
Most important matter of my findings is that there were plenty of cases of subdislocation or so-called “Perthes' disease-like changes” in 23.5%. Strictly speaking, this ratio would promote when exactly examined, and when the limitation of mobilities is considered the anatomical cure would be far diminisch. But the anatomical result of the infants under one year is far good than the older. Early treatment is very important for the congenital dislocation of hip joint.
