Growth-related Radiographic Changes in Cases of Congenital Dislocation of the Hip

Radiological results of 74 congenitally dislocated hip joints, which had been reduced by the Pavlik harness or manual reduction were assessed using Severin's classification at the ages of 6, 10, and 15 years or later. Although approximately a half of the joints showed a temporary improvement in Severin's grading at the age of 10 years, there was no uniform pattern of growth-related change for classification. The results of this study reconfirmed the importance of follow-up until skeletal maturity.
