Objective: Although the Pavlik Harness (PH) is the most utilized treatment for developmental dysplasia of the hip (DDH), the ideal treatment protocol (frequency of clinic visits in the first month and daily wear duration) for Barlow + hips (reduced but dislocatable) has yet to be defined. Methods: This study compared DDH patients with Barlow hips who were treated with 23 vs 24 h per day PH wear and weekly vs every other week visits. Clinical success was defined as a stable hip that did not require closed or open reduction, or the use of an abduction orthosis prior to achieving clinical stability. Radiographic success was based on the acetabular index at 2-year follow up. Results: Sixty-five patients (75 hips/58 females) with Barlow hips had a mean age of presentation of 15 ± 12 days (range 4–70) and mean follow-up of 33 ± 17 months (range 6–90). There was no difference in clinical or radiographic success rate between 23 h vs 24 h wear groups (p > 0.99 both) or the Frequently vs Infrequent visit groups (p = 0.49 both). Overall clinical success rate was 97% (73/75 hips) and radiographic success rate at 2 years was 97% (58/60 hips). Conclusion: A strict, weekly clinic visit and 24-h PH regimen may not be necessary to obtain good clinical and radiographic outcomes in infants presenting <6 months of age with Barlow positive hips. Level of evidence: Therapeutic, Level III.
