- Treated with Pavlik harness
- Assessed and treated at the SickKids Baby Hip Clinic
Exclusion Criteria:
- Underlying neuromuscular disease
- Teratologic hip dysplasia
- Prior treatment at other institutions
- Non-compliance with treatment protocol

Active Comparator
Experimental
Comprehensive Ultrasound Group
Limited Ultrasound Group
Children in the comprehensive ultrasound protocol group will follow the current standardized treatment protocol used at the Hospital for Sick Children in Toronto, Canada. For children presenting with stable hip dysplasia, Pavlik harness (PH) treatment is initiated at the initial visit (week 0) and runs for a total of 12 weeks. Children return to clinic at weeks 2, 5, 8 and 12 for clinical and ultrasound examinations to ensure that the harness is fitting correctly, to screen for PH complications and to monitor acetabular development.
Children in the limited ultrasound protocol group will receive the same treatment as described for the comprehensive ultrasound group above, except the ultrasound imaging conducted at weeks 2, 5 and 8 will be omitted. Children will still return to clinic at 2, 5, and 8 weeks for clinical examination, which includes the assessment of the Pavlik harness fit and screening for complications.
