Improving the detection of Developmental Hip Dysplasia in Infants



Developmental Dysplasia of the hip (DDH) is a problem of the hip in babies. Babies can be born with a hip that is completely out of the socket (‘dislocated’), or one that wobbles in and out (‘subluxes’). If untreated, DDH is strongly linked to early hip arthritis and the need for a hip replacement in early adulthood.


If identified in the weeks after birth, 90% if babies can be treated with a removable brace, that the child typically wears for 6-8 weeks over their clothes. If identified later, the child often needs invasive surgery to put the hip back in position. There is a national screening programme that aims to identify DDH, through clinical examination and, when needed, ultrasound. Every baby born in England has the details of the screening assessment entered onto a national computer system (called Smart4NIPE). Newly, the system has started to collect details of the clinical examination, ultrasound tests and treatment.

We have a broad programme of research that is seeking to improve the detection and treatment of infant hip dysplasia. This includes the

  • development of novel diagnostics devices (i.e. using machine vision and more traditional devices) and
  • development of large-scale clinical trials of both treatment and screening interventions to occur within routine care. These will supplement our existing portfolio of digital trials (,, etc).

We are always keen to talk to people who bring passion about what you do and are interested in working with us - from a range of backgrounds including:

  • medicine,
  • allied health professions,
  • computer science,
  • statistics

The PhD project should to fit with what we do – to drive our group forward – though we need your ideas and passion to define the project – as everyone is more successful if they do things that they enjoy!

We expect:

We have three core requirements:

  • First and above all, you’re kind – life is too short to work with people who aren’t.
  • Second, it’s important that you like working in an academic group that does things differently.
  • Third, you relish autonomy, bring ideas and passion for your research and are prepared for large amounts of responsibility and honest feedback.

The rules are you also need a First or Upper Second Class Honours Degree in a relevant subject (i.e. statistics, law) and/or a Degree in Medicine/ Dentisty.

Our offer: You will join a vibrant Paediatric Orthopaedic Research team in the Department of Women’s and Children’s Health, University of Liverpool run by Professor Daniel Perry (primary supervisor). This PhD project provides exceptional opportunities for the student to benefit from diverse expertise and to be exposed to research that will bring real benefit to children and young people and their families.

How to apply: Please send the following documents as a single PDF file to 1. Cover letter 2. CV 3.details of 3 references.
