The doctor performing life-changing surgery on a ship

Fudia, 10, from Sierra Leone had to have life-transforming surgery to straighten her severely bowed legs

There is an "enourmous need" for life-changing surgeries on the world's largest floating hospital, an Oxford surgeon says.

Rachel Buckingham spends most of her time working as a consultant paediatric orthopaedic surgeon at Oxford University Hospitals Trust.

But twice a year, she volunteers with Mercy Ships, to provide free surgeries to children who would not have access otherwise.

Fudia, a 10-year-old from Sierra Leone, is one of those children. She now stands 14cm (5.5in) taller after Dr Buckingham operated on Fudia's severely bowed legs.

Fudia received physical therapy after the surgery to help her learn to walk again

The international charity, Mercy Ships, organised the three-hour surgery performed by Dr Buckingham.

She said: “I will never forget the first time I met Fudia. Every step was an agonising effort. Her legs were so severely twisted that walking was a daily battle.

“I’ve met many children who need urgent surgery, but something about Fudia’s quiet courage struck me deeply.

"Despite the suffering she’s endured, losing her parents at a very young age, being turned away from hospitals that couldn’t help her, she held on to hope.”

Fudia was diagnosed with Blount's disease, a condition which causes severe leg deformities in young children and adolescents.

The condition caused her legs to bow and feet to turn inward at 90 degree angles.

Her uncle and guardian, Joseph, explained: “We noticed it the very first day she was born, her legs were not normal.”

Both Fudia's parents had died by the time she was seven and her uncle Joseph said school was difficult because she was "mocked".

Dr Rachel Buckingham volunteers on Global Mercy and says there was something about Fudia's case which stayed with her

Determined to find help, Joseph took his niece to Freetown, the capital of Sierra Leone, to seek treatment at local hospitals.

They were advised to wait for the return of Mercy Ships, so Joseph moved his family to Freetown, where they waited for six years for a ship to arrive in 2023.

Dr Buckingham carried out the surgery as she volunteers with Mercy Ships twice a year, doing one rotation on board the Global Mercy and the other on Africa Mercy.

She said about 90% of the surgeries they offer are in Sub-Saharan Africa.

The doctor explained: "It's a fabulous charity, we have people who volunteer from around 60 different countries and we all come together to live and work together and these ships provide surgery for people who would otherwise not have access to safe or affordable surgery."

Dr Buckingham said Fudia is "doing great" and now able to walk with less pain.

She continued: "The smile says it all, she's doing wonderfully she can now walk more easily and that means she can go to school and look forward to a future with hope."

The Oxford surgeon is preparing to return to Sierra Leone for three weeks in January 2025.

She added: "The need is enourmous, there are hundreds and hundreds of children just like Fudia who need this life changing surgery."
