Hip terms
The biggest 3 RFs for Developmental Dysplasia of the Hip (DDH) are all related to pregnancy, which are ()

- Twins
- First borns
Familial link is the biggest RF (30x)
DDH usually affects the (left/right) hip the MOST
Left hip
In a patient with trendelenburg sign, you notice that they tend to dip towards their right side. You suspect that their () hip is weak.
Left hip
The leg that is STRAIGHT is the WEAK side
T/F: Hip clicks suggest DDH
False, they can be normal!
DDH is diagnosed using the two baby hip maneuvers. Describe both!
- Barlow: Adduct and push
- Ortolani: Abduct and pull
Bad Barlow = trying to dislocate by pushing hip out.
Out of subluxated, dislocated, and dislocatable, the most severe form of DDH is…
Dislocated
The standard way to diagnose DDH is…
US
There are 3 indications to US an infant for DDH:

- Any child born () >= 34 weeks gestation
- () of DDH
- Instability on examination
- Born breech
- FHx
Generally, you do not XR for DDH until…
6 months
FYI iknow her slide says 4, but i think she said 6 months verbally twice
If you have a positive (Barlow/Ortolani), you REFER TO A SPECIALIST
Ortolani
get On the phone with Ortolani!!!
Barlow is observe and follow.
Treatment of DDH depends on age range:
- 0-6 months: ()
- 6-18 months () reduction + () for 2-3 months
- 18m - 6y = () reduction vs () reduction
- > 6y = ()
- 0-6 = pavlik harness
- 6-18m = closed reduction and spica casting for 2-3months
- 18m-6y = open vs closed reduction
- > 6y = no tx
