[Follow-up and ultrasound-controlled early treatment of hip dysplasia]

Area of Science:

• Pediatric Orthopedics
• Diagnostic Imaging
• Developmental Biology

Background:

• Congenital dysplasia of the hip (CDH) is a common developmental condition.
• Early diagnosis and treatment are crucial for optimal outcomes.
• Ultrasound is a primary imaging modality for infant hip screening.

Purpose of the Study:

• To evaluate the reliability of hip ultrasound in assessing hip development.
• To investigate the effectiveness of sonographically guided therapy for CDH.
• To compare ultrasound findings with radiological outcomes.

Main Methods:

• Prospective study of 470 infants from a hip-screening program.
• Clinical and ultrasound follow-up assessments.
• Radiographic evaluation (X-rays) at the end of treatment for hips managed with abduction devices.

Main Results:

• Mature hips showed no deterioration.
• 88% of immature hips matured spontaneously; 12% required casting.
• 68 pathological hips treated with abduction devices showed improvement, reaching a 60-degree acetabular angle by 80 days.
• All hips demonstrated normal acetabular indices post-therapy, though 6 girls showed later deterioration.

Conclusions:

• Ultrasound is a reliable tool for monitoring hip development and guiding CDH therapy.
• While early treatment is effective, long-term radiographic monitoring is essential to detect late-onset deterioration.
• X-ray follow-up is recommended even after successful ultrasound-guided treatment for CDH.
