Adaptation of the Graf hip ultrasound system for a newborn DDH screening program in the humanitarian Swiss Mongolian Pediatric Project (SMOPP)

Purpose: In Mongolia, a developing country in Central Asia, SMOPP has introduced a strategy for early detection and treatment of developmental dysplasia of the hip (DDH). A big screening study with 8356 newborns showed a high incidence of DDH (2%) and a remarkable treatment success with a simple and safe reusable abduction device. In the study, we had employed the gold standard in DDH classification of Graf differing 10 types. Yet, for daily use in our program, it proved to be rather complicated and extensive. Furthermore, different types of dysplasia did not lead to different treatment strategies. In order to s…
