Hip casts DDH

Hip casts

We put the hip casts only when we are sure that the head is freely in the acetabulum and we can check
the blood supply by ultrasound, if in the acetabulum there is an obstacle, the most often hypertrophied ligament, 
placing the plaster does not make sense and only causes total ischemia.  If the hip is unstable and the head does 
not stick in the acetabulum, we put it on either after an over head lift or rehabilitation and check the blood flow
in the ultrasound plaster cast for a maximum of 4 weeks and do ultrasound and x-ray.  Blood supply disorders are 
the main reason for the lack of reconstruction of the acetabulum; therefore, it is necessary to make a very precisely 
matched plaster dressing with a maximum abduction of 45 degrees and check with ultrasound whether there are any blood 
circulation disorders.  if there is no improvement after the plaster cast, we have disturbed the blood supply and should be 
put under ultrasound control again. without such a possibility, we should give up plaster casts.
