Learning objectives
To review DDH’s multimodality image algorithm used for diagnosis and follow-up,
due to the fact that early diagnosis is important to institute appropriate treatment and reduce the incidence of long- term complications.
Background
The current recommendations are for the term “developmental dysplasia of the hip” (DDH) as a replacement for the previous name of “congenital hip dislocation” (CHD).
This new nomenclature includes all spectrum of abnormalities possible for hip disorders among newborns,
because DDH is a generic term that describes a wide range of anatomical abnormalities of the hip,
which may be congenital in nature,
or may develop during children’s first months of life.
DDH describes the wide spectrum of abnormalities that affect growing hips,
from dysplasia to...
Findings and procedure details
The patient age is essential,
not only regarding the recommended imaging modality for the initial workup,
as well as choosing suitable treatment.
Different screening strategies have been described,
including clinical examination alone,
selective ultrasound screening,
and universal ultrasound screening.
Selective ultrasound is indicated in patients with associated risk factors or abnormal clinical examinations (14).
Ultrasound(US) is the investigation of choice to evaluate DDH in infants younger than four to six months of age,
when capital femoral epiphyseal ossification usually occurs,
and is useful to diagnose...
Conclusion
DDH is a disease that is commonly encountered by both the pediatric radiologist and the general radiologist.
It has long been evaluated with a standard imaging algorithm,
typically consisting of ultrasound and radiography,
and although radiography is the mainstay of diagnosis inlate DDH,
CT and MRI have increasing roles in assessing DDH,
underlying pathoanatomy,
inplanning appropriate treatment,
as well,
as identifying its complications.
