抄録

In treating congenital dislocation of the hip, the importance of early screening should be emphasized. We summarized the results of orthopaedic examination for neonates who were born from Oct. 1977 to Dec. 1994. During this time 11370 babies were born in the maternity ward of Showa University Fujigaoka Hospital. A total of 8886 babies (78.2%) were examined, including 4506 male babies and 4380 female babies. Regarding the click sign, in which the instability of the hip joint can be felt by allowing the femoral head to slip in and out of the joint cavity, Ortolan's click sign was positive in 6 cases (6 joints) and Barlow's click sign was positive in 8 cases (10 joints) . Of the cases tested by Barlow's click sign, 0.1 % were positive. In these cases one was affected with Larsen's syndrome. Three cases that tested negative using the click sign were found to be dislocated at the follow-up time during infancy. In the click sign-positive cases, plaster cast fixation was performed in two patients, the remaining five patients were treated by a Pavlik harness and one patient was treated by abducted diaper. From follow-up examinations at an average age of 5.4 years satisfactory results were obtained in seven cases; only one case treated by plaster cast fixation showed bilateral slight aseptic necrosis of the femoral head. Although click sign-positive cases have been decreased due to primary prophylaxis from birth, the neonatal examination is essential for detecting the dislocation of the hip in early life.
