Abstract:

Introduction and Objective: Congenital dislocation of the hip (CDH) is a commonly encountered anomaly in our country and successful results can be achieved by early diagnosis and treatment. The aim of our study was to identify the cases of developmental dysplasia of the hip (DDH) among newborn babies and infant those in the early nursing period by the hip ultrasonography (USG) as well as to provide early treatment opportunities.Cases and Method: 300 infants who were being followed up in the healthy children clinic of our hospital, between September 2005 and September 2006, were enrolled in our study. Crossexamination was made with respect to risk factors of DDH. Ultrasonography was applied on all cases that underwent physical examination of the hip. The hips were evaluated according to the graf and dynamic ultrasound method. Type 2a hips were followed up while type 1 hips were excluded from the follow-up program. Type 2b cases were referred to the orthopedic clinic. Results: The DDH examination covered a total of 300 infant including 134 girls (4.7%) and 166 boys (55.3%). They were aged between 1–4 months. There was a medical history of breech position in 18 (6%) of the cases, oligohydramnios in 8 (2.7%), multiple pregnancy in 14 (4.7%) and a history of the first child being a girl in 86 (28.7%) of the cases. During the orthopedic examination torticollis was identified in 2 (0.7%) of the cases, foot deformity in 4 (1.3%); meanwhile hip examination demonstrated pili asymmetry in 10 (3.3%) and abduction limitation in 4 (1.3%) cases. The hip examinations of 286 infants were normal. USG examinations were performed on all cases. Graf Type 2a hips were determined in 28 (9.3%) cases. In the hip USG examinations performed a month later, graf type 2b hips were identified in 3 (1.2%) cases and evaluated as hip subluxation. These cases were referred to the orthopedic clinic. Conclusion: In this study, we established the importance of USG examinations performed on infants in order to diagnose the cases of developmental dysplasia of the hip in and increase treatment success. Our country is taken into consideration at least the conditions of the risk group must be made with USG scan
