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.) Examination immediately after birth; best results without opration and up to 1% slight grade 1 necrosis
3.) 3-4 months; 1/100 the risk of necrosis (avn) and the extent will be less if it gets worse
4.) 6-7 months; 1 in 40 will worsen and the acetabulum will be incorrect.
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
In US are born about 3 milions newborn and 500 thousend replacement hips a year 1 to 6.;
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.
Clinical examination statisyic: compare to ultrasound screening
1in10
infants are born with hip instability
(1 in 14 with DDH)
1in100
infants are treated for hip dysplasia.
( 1 in 1 000 are treated )
1in500
infants are born with completely dislocated hips.
( in ultrasond examination newborn 1 in 50 000 )
1in10
total hip replacements is because of hip dysplasia.
9x
Adult hip dysplasia 9 times more common than infantile hip dysplasia.
(avn?:no ultrasound screenning? my opinion)
<50years
The most common cause of hip
the International Hip Dysplasia Institute.
In fact, 10% of all clinically unstable hip joints in newborns endo joint replacement in US
actually as you wish of patients:
but Norway has about 2% hip joint replacement where there is a lack of orthopedists and other post-pillar
