Could babies with mild hip dysplasia skip the brace?
NCT ID NCT05869851
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether simply monitoring babies with mild hip dysplasia is as good as using a brace. The brace, called a Pavlik harness, keeps the hips in proper position but can be hard on families. The trial will follow 514 infants under 3 months old across seven countries to see if careful observation leads to the same hip development as bracing.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Pavlik Harness (abduction brace)
- What this could lead to
- If successful, this could show that many babies with mild hip dysplasia can avoid bracing and its daily challenges, while still achieving normal hip development.
- What could go wrong
- This is an early-stage non-inferiority trial, so results may not apply to all cases. There is a risk that observation alone may not correct the hip condition as effectively as bracing.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Patients presenting with radiological dysplasia of a clinically stable hip under three months (12 weeks) of age * Radiological dysplasia will be defined as a centred hip with an alpha angle between 43 and 60 degrees and a percent coverage of the femoral head (FHC) greater than 35%, as measured on ultrasound exam Exclusion Criteria: * Patients presenting with radiological dysplasia older than three months (12 weeks) of age * Patients presenting with clinical hip instability (Ortolani or Barlow positive) * Patients with known or suspected neuromuscular, collagen, chromosomal or lower-extremity congenital abnormalities or syndromic-associated hip abnormalities * Patients who received prior treatment (i.e. Pavlik harness) for DDH
