Standard conservative treatment commonly includes a Pavlik harness. This exploratory randomized pilot study will assess whether a gentle manual intervention applied to the coxal bone, in addition to conventional orthopedic treatment, is associated with a greater change in ultrasound-measured femoral head coverage than conventional orthopedic treatment alone. Thirty infants aged 1 to 5 months with confirmed unilateral or bilateral DDH (Graf IIa to III) will be randomized to two parallel groups. The experimental group will receive one manual intervention session per week for three consecutive weeks in addition to conventional orthopedic treatment. The comparison group will receive conventional orthopedic treatment alone. Ultrasound assessments will be performed at baseline (T0) and after the intervention period (T1). In infants with bilateral DDH, both dysplastic hips will be evaluated at both time points and recorded separately. A secondary objective is to describe parental acceptability of the manual intervention and study procedures. As a pilot study, the project is intended to provide preliminary information on the direction and variability of the intervention effect, parental acceptability, and study feasibility to inform a future larger trial.",[59,60],"Developmental Dysplasia of the Hip (DDH)","Congenital Hip Dysplasia",[62,63,64,65,66],"Developmental dysplasia of the hip","Pilot study","manual therapy","coxal bone","infant","NOT_YET_RECRUITING","2026-08-05",{"date":70,"type":71},"2026-08-11","ACTUAL",{"date":73,"type":53},"2026-08",{"date":75,"type":53},"2027-09",{"name":5,"class":6}]
