Ages at the final examination ranged from 6 years 1 month to 21 years and only 5 cases over 15 yrs of age complained mild hip pain, whereas 51 cases were assessed as poor according to Severin's standard. 15 hip joints of 10 cases were prognosticated poor during the course of observation and operative procedure of Salter's pelvic osteotomy or that combined with derotation-varus osteotomy of femoral neck were performed at the ages between 7-9. The result was excellent except one which was poor due to technical fault. Retrospectively examined, Pavlik bandage was placed in hip joints with poorer CE angle regardless whether they were diagnosed as acetabular dysplasis or subluxation, and no significant difference in CE angle was noted in the X-rays taken at the final examination. This fact was thought to prove that there were hip joints in which placement of Pavlik bandage was effective. In the cases over 14 years of age in which X-rays were repeatedly taken after the initial examination, it was noted that CE angle was over 20° during the age of 5-7 in the hips which could be classified to Ia (excellent) at the final examination and that was less than 15° in the hips which were classified to III (poor). This suggested that hips with less than 15°CE angle the age of 5-7 years would better be operated.}, pages = {772--785}, title = {先天性臼蓋形成不全および先天性股関節亜脱臼症例の追跡調査}, volume = {103}, year = {1989} }
