Abstract:

Abstract Objective: The aim of this study is to determine the risk factors associated with sonographic deterioration of the hip in children aged 4-8 weeks with Type 2a hip detected during sonographic screen due to developmental dysplasia of the hip (DDH). Material-Methods: 3492 hips of 1746 children aged 4-8 weeks who applied for DDH screening in a single center between January 2018 and December 2020 were retrospectively examined. A total of 360 hips of 279 children, of which 195 (70%) were women and of which 84 were men (30%), who applied to our hospital and diagnosed with Type 2a in the sonographic examination and were followed up 4 weeks later and underwent sonographic examinations, were included in this study. Results: In the subsequent sonographic examinations of 360 hips, of which 91 (32.6%) were right, of which 107 (38.3%) were left, of which 81 (29%) were bilateral hips of cases, 85% of the hips (n=306) recovered spontaneously and 15% (n=54) deteriorated sonographically. On the other hand, it was seen that there was a statistically significant correlation between breech presentation and neurological disease (p=0.000) and sonographic deterioration (p=0.002, p=0.000, respectively). The risk of sonographic deterioration was found to be 5.3 times higher in those with breech presentation than in those without, and 9.6 times higher in those with neurological disease than in those without. Conclusion: Neurologic disease and breech presentation are independent factor for sonographic deterioration in children with Graf Type 2a hip detected during sonographic screening for DDH. It is important to be careful in the follow-up of these children and to inform the families.
