Does active sonographic surveillance improve or maintain radiographic hip appearance at 1 year in infants with mild stable hip dysplasia compared to immediate abduction splinting?
In infants with mild stable hip dysplasia, active sonographic surveillance reduces the need for immediate splinting without compromising 1-year radiographic outcomes.
Supports sonographic surveillance to minimize unnecessary splinting in mild stable hip dysplasia; extends RCT evidence for conservative management.
### Design Randomised controlled trial. ### Allocation Opaque, sealed and numbered envelopes. ### Blinding Outcome radiograph assessment was blinded to any therapeutic intervention. ### Setting Paediatric radiology and outpatient department in a Norwegian university hospital. ### Patients 128 infants aged 1–3 days old, with mild stable hip dysplasia defined ultrasonographically and clinically. ### Intervention Either immediate abduction splinting for at least 6 weeks with subsequent sonography determining further treatment (control group), or active sonographic surveillance at 6 weeks and 3 months determining splinting (investigation group). ### Outcomes Radiographic appearance of the hips at 1 year, with groups being compared using the acetabular index, a measure of acetabular formation. ### Follow-up period 1 year. ### Patient follow-up All 128 patients … Correspondence to Birmingham Children's Hospital NHS Foundation Trust, Birmingham, UK

C. E. Bache (2010) conducted an RCT in Mild stable hip dysplasia (n=128). Active sonographic surveillance vs. Immediate abduction splinting was evaluated on Radiographic appearance of the hips at 1 year (acetabular index). Active sonographic surveillance of infants with mild stable hip dysplasia reduced the need for active treatment compared to immediate abduction splinting.
