[Radiographic study of the hip in infancy and early childhood]
1Orthopädischen Universitätsklinik Heidelberg.
Insights
While sonography is useful for screening infant hip dislocation, radiography remains essential for diagnosing and managing treated or complex hip joint conditions in children.
Area of Science:
- Pediatric Radiology
- Medical Imaging
- Orthopedics
Background:
- Sonography is increasingly preferred for infant hip examinations, reducing radiation exposure.
- However, sonography's role is primarily limited to screening for congenital hip dislocation and dysplasia.
Purpose of the Study:
- To clarify the role of different imaging modalities in evaluating pediatric hip joint conditions.
- To emphasize the continued importance of radiography for specific diagnostic needs.
Main Methods:
- Review of current practices in pediatric hip imaging.
- Comparison of sonography, radiography, arthrography, and advanced imaging techniques.
- Discussion of diagnostic goals and pathomorphologic interpretation.
Main Results:
- Sonography is effective for initial screening of hip dysplasia in infants.
- Radiography and arthrography are indispensable for diagnosing and managing treated or complex hip joint pathologies.
- Computed tomography is not indicated for these conditions.
Conclusions:
- Radiologic examination remains the gold standard for definitive diagnosis and management planning of pediatric hip joint issues.
- Future advancements in magnetic resonance imaging may offer new diagnostic capabilities.
Abstract:
In the age of sonography, there is increasing disapproval of radiologic examination of the hip in infancy and early childhood. Justifiably, the sonogram has replaced the X-ray in many examinations of the hip joint in infants and small children, thus sparing them radiation exposure. It must be remembered, however, that sonography is primarily a screening method for detecting congenital hip dislocation and dysplasia in infancy. There is still no substitute for radiologic examination of hip joints which require treatment or have been treated. Performance of survey radiograms, and if necessary arthrography, with a specific diagnostic goal permits an interpretation of all pathomorphologic changes associated with hip dislocation in infancy and early childhood. There is no place for computerized tomography in this context. It is still impossible to predict the extent to which, in the future, magnetic resonance imaging, with new coil configurations and shorter examination times, will open a new chapter in hip joint examination.
