Congenital Hip Dysplasia

Developmental dysplasia of the hip (DDH) is a developmental abnormality of the infant hip in which the acetabulum does not adequately cover the femoral head. 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.

Developmental dysplasia of the hip (DDH) is the most common hip condition affecting infants and children. DDH represents a spectrum of issues affecting the hip joint - a "ball-and-socket" joint. When the femoral head (the "ball) is seated properly in the acetabulum (the "socket"), the hip is stable and can develop normally. However, when the femoral head is not well-seated, the hip can become unstable or dislocate. This instability or dislocation of the femoral head prevents the hip joint from developing normally during infancy and early childhood. If left undetected or untreated, it can lead to debilitating complications later in life. Development of a comprehensive, prospective international registry for all infants and children with DDH will provide the potential to impact all infants born, not only in British Columbia, but around the world. The purpose of this initiative is to identify best practices and standardize treatment and management strategies in order to optimize clinical and functional outcomes for patients with DDH. This registry includes targeted specific outcomes that will be investigated, in addition to the general collection of data on all patients diagnosed with any form of DDH up to the age of 10 years.
