Hip sonography--how reliable? Sector scanning versus linear scanning? Dynamic versus static examination?

Area of Science:

• Pediatric Orthopedics
• Diagnostic Imaging

Background:

• Clinical and historical data are unreliable for diagnosing hip dislocations and dysplasias.
• Ultrasonography is a routine procedure in Europe for hip joint assessment.

Purpose of the Study:

• To evaluate the reliability and effectiveness of ultrasonography in diagnosing and managing hip developmental abnormalities in infants.
• To highlight the advantages of ultrasonography over traditional methods.

Main Methods:

• Utilized linear transducers for hip joint examinations, avoiding distortions caused by sector scanners.
• Employed static and dynamic ultrasonographic approaches, complemented by a reference level for measurements.
• Trained specialists conducted examinations to ensure accurate diagnosis.

Main Results:

• Ultrasonography reliably detects hip joints requiring treatment, with reproducible results.
• Early diagnosis (within six weeks) allows for effective conservative management.
• Conservative treatment for infants up to 4.5 months old led to the disappearance of femoral head necroses and a significant decrease in surgical interventions.

Conclusions:

• Ultrasonography is an indispensable tool for diagnosing hip developmental abnormalities in infants.
• Early and accurate diagnosis facilitates successful conservative treatment, minimizing complications and the need for surgery.
• The combination of static and dynamic ultrasonographic methods provides comprehensive assessment of hip joint stability and development.
