Stabilisation and development of the hip after closed reduction of late CDH

Area of Science:

• Pediatric Orthopedics
• Medical Imaging
• Developmental Biology

Background:

• Developmental Dysplasia of the Hip (CDH) is a condition affecting hip joint development.
• Late diagnosis of CDH often requires intervention to ensure proper joint formation and stability.
• Conservative management is preferred when feasible to avoid surgical risks.

Purpose of the Study:

• To evaluate the utility of ultrasound in assessing hip anatomy and stability post-reduction in infants with late CDH.
• To determine the effectiveness of conservative treatment (splintage) guided by ultrasound findings.
• To explore the potential of ultrasound to reduce the necessity of open reduction procedures.

Main Methods:

• Ultrasound examinations were performed on 15 infants (2-15 months) undergoing closed reduction for unilateral late CDH.
• Infants were treated with splintage in abduction, with stability assessed over time.
• Changes in femoral head position, size, and soft tissue interposition were monitored ultrasonically.

Main Results:

• Conservative splintage achieved complete hip stability in all infants within 3-13 weeks.
• Initial lateralization of the femoral head due to soft tissue resolved over time.
• The femoral head on the affected side normalized in size, indicating successful treatment.

Conclusions:

• Ultrasound is a valuable, safe tool for evaluating hip joint stabilization after closed reduction in late CDH.
• Ultrasonic assessment improves treatment by visualizing pathology, potentially decreasing the need for radiographic imaging.
• Increased use of ultrasound may reduce the requirement for open reduction in this pediatric age group.
