[Nonsurgical treatment of developmental dysplasia of the hip].

The introduction of hip ultrasound for developmental dysplasia of the hip (DDH) has led to earlier diagnosis and treatment of this condition. The younger the child, the greater the potential of acetabular remodelling. An early-initiated, differentiated therapy according to the Graf classification has led to good treatment results. Nevertheless, there is still a number of residual dysplasia and a risk for late sequelae even after successful ultrasound-guided therapy. Therefore, long-term follow-up of treated hips until skeletal maturity is necessary. Whereas there is no doubt about the good results of the treatment we apply, its economic effectiveness still has to be proven.
