Until recently, it was believed that a man is born with acetabular maldeformation , but this is not true, it turned out that the normal acetabulum may

deteriorate;

, the earlier name was  changed from congenital dysplasia and  hip dislocation (Lcc) for developmental dysplasia and DDH dislocation.

 

1 ultrasound examination is never enough to avoid a disability in a child.

 

If it is to be 100% without the risk of necrosis (avn)  and deformation of the acetabulum, it should be examined 4 times:

in the absence of any  test:

 

The statistics are absolute : each step results in someone's disability if we do not come to the next check-up or the first check-up is too late ;

1 / 20,000 children are born with the head outside the acetabulum,

each day of delay is usually important with a family interview

 

1/50 is born with a dislocation but with a head in the pan in 95% with a family interview

the later the first examination, the more

1/10 is worsening  to completely dislocated  hip in 14 days.

 

1.) Examination immediately after birth; best results without opration and up to 1% slight grade 1 necrosis

3.) 3-4 months; 1/1000 the risk of necrosis (avn) and the extent will be less if it gets worse

4.) 6-7 months; 1 in 5,000 will worsen and the cup will be incorrect. if 1 test is performed later: 4-6 weeks of age;

1/1000 will be operated on or the acetabulum will not rebuild perfectly and 2% of the total number of joint replacement surgery will end 3-4 months;

1 risk of necrosis (avn) 1-2% 3-4 degree

 

Hip defects with which babies are born are the most difficult to treat, therefore the first examination should be performed as soon as possible within 7 days.
