The role of ultrasound techniques in monitoring developmental dysplasia of the hip treatment using abduction devices

Aim: The aim of the study consist in the assessment of the utility of abduction devices in treatment of developmental dysplasia of the hip (DDH) by repetitive ultrasound (US) examinations for monitoring anatomic changes in the hip joint. Method: The study group consist in 40 patients with DDH, aged less than 6 months. The patients were assessed clinically, with greyscale and three-dimensional (3D) US. We formed 3 age groups of patients – regarding first clinical examination: first group aged less than 1 month (10 patients), the second group aged between 1–3 months (25 patients) and the third group between 3–6 mo…
