Could ultrasound scans help identify early hip problems for children with cerebral palsy?
Published on 10 March 2017
Almost 2,000 babies born each year in the UK are diagnosed with cerebral palsy.1,2 They face lifelong difficulties with movement and coordination. Many start to have problems with their hips during childhood, which can cause pain and reduce mobility. Dr Adam Shortland, of Guy’s Hospital, London, is developing a new way to screen for these hip problems, using 3D ultrasound scans. Successful screening means children who have early signs of hip problems can be offered treatment, with the aim of stopping those problems from getting worse, and sparing children from the pain and reduced mobility that goes with them.
How are children’s lives affected now?
Hip problems are common in children with cerebral palsy.3
Some children’s hip problems get so bad that their hips become dislocated. This is a severe problem, which often causes pain and makes it hard for children to stand, walk or even sit comfortably. It can cause other problems too, such as fractures and skin ulcers.
Children’s hip problems begin when the thigh bone becomes slightly out of line with the hip socket. In some children, this doesn’t pose a problem, but without treatment, it can get worse over time. If this is spotted early, more severe hip problems can be prevented.
“At the moment, we use X-rays to screen for hip problems in children with cerebral palsy,” says Dr Shortland. “Though beneficial, having repeated X-rays exposes children to radiation. Also, X-rays only provide 2D images, which aren’t as useful as 3D images would be.”
How could this research help?
The researchers are developing a new way to screen for early hip problems in children with cerebral palsy using a technique called freehand 3D ultrasound.
Ultrasound scans use high-frequency sound waves to create images of inside the body. Advantages of ultrasound scans over X-rays include the fact that they do not expose children to radiation (there are no known risks from the sound waves used) and they can provide 3D – rather than 2D – images.
“We hope to develop a safe new technique that can be used regularly to spot early hip problems in children with cerebral palsy,” says Dr Shortland. “We are also investigating whether the new technique can be used to predict whether any hip problems a child has are likely to get worse.”
Early and accurate prediction of hip problems would allow prompt treatment, with the aim of sparing children from more severe problems and the pain and disability they can cause.
