Insights
Ultrasound (US) of the hip is a valuable screening tool for infants, showing early hip alterations. This study found US agreed with clinical findings in 71% of cases, highlighting its utility in pediatric hip assessment.
Area of Science:
- Pediatric Radiology
- Orthopedics
- Diagnostic Imaging
Background:
- Infant hip conditions require early detection for effective management.
- Clinical examination alone can have limitations in diagnosing hip abnormalities.
Purpose of the Study:
- To evaluate the efficacy of ultrasound (US) in screening infant hip conditions.
- To compare clinical findings with US results in a large pediatric cohort.
Main Methods:
- Conducted Graf's method ultrasound on 1000 children aged 1 day to 8 months.
- Correlated clinical signs recorded by pediatricians with radiologist-documented US findings.
- Analyzed agreement, disagreement, false-negative, and false-positive rates between clinical and US assessments.
Main Results:
- Ultrasound findings agreed with clinical assessments in 71% of cases.
- A significant disagreement rate of 29% was observed.
- Clinical examination showed a high false-negative rate (64%) and a low false-positive rate (23%).
Conclusions:
- Ultrasound is a useful screening method for detecting early morphological and functional alterations in infant hips.
- US demonstrates superior sensitivity compared to clinical examination alone.
- Further analysis explored the correlation of clinical signs and risk factors with US findings.
Abstract:
The authors report their experience with US of the hip in 1000 children aged 1 day to 8 months. US study was carried out following Graf's method. All the children were previously examined by a pediatrician, who recorded all the clinical signs on a chart. After US examination, the radiologist recorded US findings on the same chart. Thus, US findings could be compared to clinical ones: there was agreement in 71% of cases, and disagreement in the extant 29%. Furthermore, clinics exhibited a high false-negative rate (64%) and a low false-positive rate (23%). This suggests US as an useful screening method able to show early morphological and functional alterations in the infant hip. The authors also examined the incidence of the single clinical signs and risk factors, and correlated them with US findings.
