dear Zaid,
Do not be embarrased!

DDH protocols for PT can probably not be found because the dysplasia is primarily treated by surgeons and not by PT/physio´s.

Clinical hip examination, radiographic examination or ultrasonography are the tools surgeons have.
Hips can be diagnosed radiographically as:
acetabular dysplasia ( without subluxation or dislocation),
subluxated, with associated acetabular dysplasia and
dislocated.

treatment from birth - 9 months is restrictive devices or traction
treatment 9 months and older... abduction orthesis in walkers and traction.
If the diagnosis is late ( after 2 yrs) open reduction is often necessary.

Some children, with mild acetabular dysplasia are never diagnosed.
The further development in time may lead to: further alignment problems and limping. Mild dysplasia can come to light only when patients develop a degenerative joint disease.

We physiotherapists should be alert when we see a child with a limp. The history and clinical examination should give us sufficient information to in- or exclude this possibility.

As a physiotherapist I have been involved with these children only when asked by their physician to monitor the motor development ( mostly after bracing).

Good luck.....
