Pavlik Harness initiation on Barlow positive hips: Can we wait?

We investigated if infants with a Barlow positive hip(s) have natural hip stabilization and can thus avoid Pavlik Harness (PH) treatment. We conducted a chart review for infants who presented within two weeks of life, had a Barlow positive hip, and were deferred treatment. Of the thirty infants, eighteen were treated with PH at 4–6 weeks or 12 weeks due to persistent dysplasia. Twelve infants avoided PH entirely. There were zero cases of PH failure. Parents can be counseled that deferring treatment until at least 4–6 weeks of age might avoid treatment altogether without an increased risk of harness failure.
