World-First Baby Treatment Uses Super-Elastic Springs to Reshape the Skull
A pioneering medical procedure has given new hope to babies born with severe skull conditions. One-year-old Rory Potter has become the first patient in the world to receive a new type of treatment using specially designed “super-elastic” springs to gradually reshape the skull.
The innovative treatment was developed by specialists at Great Ormond Street Hospital for Children and University College London. It uses springs made from nitinol, a flexible nickel and titanium alloy, rather than conventional stainless steel.
The breakthrough could offer a less invasive treatment option for some children with sagittal craniosynostosis, a rare condition that causes parts of the skull to fuse too early.
What Is Sagittal Craniosynostosis?
Sagittal craniosynostosis is a condition in which the skull bones fuse before a baby's brain has finished growing. The early fusion can affect the normal shape of the head.
In babies with the condition, the skull can become unusually long from front to back while remaining narrow from side to side. Rory Potter was diagnosed with severe sagittal craniosynostosis shortly after his birth in April 2025.
The condition affects approximately one in 1,800 to one in 2,000 babies in the UK. If it is not treated, it can potentially result in complications associated with brain development and increased pressure within the skull. According to information cited in the original report, possible problems can include learning difficulties, sight or hearing loss, breathing difficulties and dental problems.
Treatment is therefore often carried out during infancy, when the skull is still developing and can be reshaped more effectively.
A New Approach to Skull Reshaping Surgery
Traditional treatment for craniosynostosis can involve surgery to reshape the skull. For some children, surgeons have also used springs to gradually expand the skull following an operation.
Stainless steel springs have been used for around two decades. They are designed to apply a controlled force that gradually widens the skull, creating additional space for the growing brain and allowing new bone to develop.
However, conventional springs have limitations.
The new technology uses nitinol springs, which have what doctors describe as super-elastic properties. These characteristics allow the springs to respond more naturally as the child's skull changes during growth.
The aim is to provide surgeons with greater control over the amount of force applied to the skull while gradually guiding it toward a more typical shape.
Professor Owase Jeelani, a consultant neurosurgeon at Great Ormond Street Hospital, was part of the team responsible for developing the technology and led Rory's operation. The team believes the new springs could provide greater flexibility compared with traditional stainless steel devices.
How Do the Super-Elastic Springs Work?
One of the most important features of the new treatment is that the springs are designed specifically for each child.
Before surgery, doctors use CT scans to create a detailed digital model of the patient's skull. This information allows the medical team to understand the skull's existing shape and predict how it may respond to treatment.
Engineers then use this information to create bespoke springs designed to deliver an appropriate level of force.
Once the springs are inserted, they remain in position for a period ranging from several weeks to months. During this time, they gradually apply pressure to reshape the skull.
After the desired result has been achieved, the springs are removed.
This combination of medical imaging, computer modelling and biomedical engineering represents an important part of the treatment's development.
Rory Potter's World-First Treatment
Rory's case represents the first time this new type of nitinol spring treatment has been used in a patient.
His operation to insert the springs lasted approximately 45 minutes. He remained in hospital overnight before returning home to Derbyshire to be with his family.
Nine weeks later, doctors removed the springs after his skull had reached the desired outcome.
For Rory's family, the treatment has been an important milestone following what had initially been a worrying diagnosis.
His mother, Jo Potter, said Rory was happy, energetic and continuing to reach developmental milestones. She also praised the medical team for providing reassurance and explaining each stage of the process.
Why Could This Treatment Matter for Children?
The development of super-elastic springs could potentially change how some cases of craniosynostosis are treated.
According to the medical team, the technology may allow children to avoid longer and more invasive procedures in certain circumstances. It could also reduce the need for blood transfusions associated with more extensive surgery.
Another potential advantage is the ability to tailor the springs to the individual patient.
Every child's skull develops differently. A treatment that can be designed around a child's specific anatomy could give surgeons greater control over the reshaping process.
However, Rory's treatment is only one case, and further research and clinical experience will be needed before the wider benefits of the technology can be fully understood.
Bringing Engineering and Medicine Together
The development of the springs highlights the growing role of engineering in modern healthcare.
The project involved specialists from Great Ormond Street Hospital and University College London, combining expertise in neurosurgery, biomedical engineering, medical imaging and patient care.
Professor Silvia Schievano, who led the biomedical engineering team at UCL, described the project as the result of years of research. The technology demonstrates how engineering solutions can be developed to address complex medical problems.
The use of customised medical devices also reflects a wider trend toward more personalised healthcare. Rather than relying entirely on standard-sized equipment, modern technologies can increasingly use detailed patient data to create treatments tailored to individual needs.
What Happens Next?
Rory's successful procedure is an encouraging first step, but it is important not to view one successful treatment as proof that the technology will work in every case.
Doctors will need to continue monitoring patients and gathering evidence about the springs, including their safety, effectiveness, durability and long-term outcomes.
Researchers will also need to determine which children are most likely to benefit from the treatment and how it compares with existing surgical approaches.
For families affected by craniosynostosis, however, the development provides another reason for optimism. A treatment that can gradually reshape the skull while potentially reducing the need for more invasive surgery could become an important option in the future.
A Promising Step in Craniosynostosis Treatment
Rory Potter's treatment marks a significant moment in the development of care for children with sagittal craniosynostosis.
The use of custom-made nitinol springs combines advanced imaging, biomedical engineering and specialist neurosurgery to create a treatment designed around a growing child's skull.
While more research is required to establish the technology's long-term benefits, the world-first procedure demonstrates how innovative medical engineering can create new possibilities for paediatric care.
For Rory and his family, the most important outcome is much more personal. After facing a difficult diagnosis early in his life, he has undergone a pioneering treatment and is continuing to grow, develop and enjoy life with his family.
