Objective: Development of the hip joint is a dynamic process beginning before the delivery and continuing after it. Ultrasound (US) examination is preferred diagnostic method. US examination is performed with static method described by Dr. Graf and dynamic method described by Dr. Harcke. In both of these methods, bone and cartilage structure composing the hip joint is evaluated and typed according to Dr.Graf’s classification system. US examination is also used during the follow-up and treatment periods together with this classification system. Material and Methods: In our study, we compared follow-up sonographic worsening of the hips which were evaluated to be in favor of type 2a at the first US investigation between January 2008 and December 2012 with the first presenting symptoms and the parameters predisposing to developmental dysplasia of the hip (DDH). Results: In the study, 80 female (n=99, [69%]) and 36 male (n=43, [31%]) babies were evaluated. There were 73 babies with type 2a (+) (n=88, [62%]) and 43 babies with type 2a (-) (n=54, [38%]). There were 13 babies with family history (n=14, [9.9%]) and 40 babies of primiparae mothers (n=48, [33.8%]). One hundred and eleven babies (n=135, [95.1%]) gained physiologic appearance up to 3 months. Risk factors and sonographic evaluation findings were evaluated according to ultrasonographic worsening. There is no statistically significant difference between gender and family history, being right and/or left hip, being Type 2a (-) or (+) with ultrasonographic worsening. Conclusion: In our study, ultrasonographic worsening was determined in 4.9% of the cases. No statistical significance was determined between DDH risk factors and sonographic worsening. The cases determined to have physiological immaturity at the first US investigation should be followed-up carefully during first 3 months regardless of risk factors.
