Developmental dysplasia of the hip (DDH)

Early diagnosis and treatment of hip dysplasia

The Harris International Patient Centre at Great Ormond Street Hospital offers a new and unique service for the diagnosis and treatment of developmental dysplasia of the hip (DDH). Mr Andreas Roposch, Consultant in Paediatric Orthopaedic Surgery and Honorary Reader in the Institute of Child Health, provides this exciting new service.

Hip dysplasia is the most common congenital musculo-skeletal disorder. It is a condition characterised by varying displacement of the proximal femur from the acetabulum. There is typically poor development of the acetabulum. Physical examination is often not sensitive enough to detect hip dysplasia, especially in early stages of the condition, or in neonates. Ultrasound is the imaging technique of choice to diagnose DDH in the neonatal age. It is generally accepted that the earlier DDH is detected, the shorter the course of treatment, and the better the outcomes. Milder forms of DDH include hip instability, anatomic dysplasia, and hip subluxation. If left untreated these forms can progress to hip dislocation. If hip dislocation is detected late it requires prolonged treatment including the need for general anaesthesia, hip spica cast, or open reduction by surgical means.

Our service

  • ultrasound-based diagnosis of hip dysplasia
  • ultrasound-guided early harness treatment of hip dysplasia
  • clinical examination and ultrasound during the same consultation, so there is no need to schedule a separate appointment for the ultrasound test
  • we can guarantee an appointment within a few days upon referral in order to ensure an early diagnosis and treatment of DDH should it be indicated


Our private consulting rooms and ultrasound facilities are located in the new Harris International Patient Centre in light, modern, child friendly surroundings.

Our in-patient rooms are specifically designed for modern paediatric healthcare but also have en-suite bathrooms and a bed to enable one parent to stay overnight. Each room has its own TV with access to international satellite channels.

We also provide advocacy and interpreting services to support families from overseas during their stay with the hospital.
