Alfie Phillips, a nine-year-old boy from Northampton, has turn into the first person in the United Kingdom to undergo pioneering surgery to lengthen a leg affected by a rare congenital condition. The procedure, performed at Alder Hey Children’s Hospital in Liverpool, successfully added three centimetres to Alfie’s right leg, which was more than an inch shorter than his left due to fibular hemimelia.
Fibular hemimelia affects fewer than one in 40,000 births, causing incomplete or absent development of the fibula – the smaller bone in the lower leg. For Alfie, this meant a significant discrepancy in leg length that specialists predicted would grow to six centimetres by the time he reached sixteen years old. Prior to the surgery, which took place in March 2025, Alfie faced the prospect of treatment involving an external frame fixed to his bone with pins and wires, a method carrying risks of pain, infection and scarring.
“I ran a bit different, and I couldn’t skip,” Alfie told the Press Association, describing the challenges he faced before the operation. “By the time I was five, it started to acquire a bit annoying. If they ever wanted a conversation, other than my friends, it was always going to be about my condition.” He added that, growing up with the condition, he hadn’t initially perceived it as different, but the disparity became more noticeable as he aged.
The innovative technique employed at Alder Hey involved implanting a lengthening nail on Alfie’s thigh bone. This nail was then slowly extended over time using magnets, stimulating the growth of new bone tissue to fill the gap. While lengthening nails have been used in adults, this marks the first time the procedure has been successfully implemented in a young child, due to previous concerns about potential damage to growth plates.
Alfie’s mother, Laura Ducker, an NHS midwife, explained that Alfie was diagnosed with fibular hemimelia within six months of his birth. His father initially noticed Alfie had only three toes on one foot. “It really didn’t affect him massively when he was little,” Ms. Ducker said, “but as he got older, that leg difference became a lot more significant.” She discovered consultant orthopaedic surgeon Nick Peterson at Alder Hey through a Facebook support group and sought his advice, concerned about potential future problems with Alfie’s hips and joints.
According to Mr. Peterson, Alfie’s recovery has been remarkably swift. “After about seven days, his pain score went down to zero out of 10, which is pretty much unheard of,” he stated. “He didn’t require anything other than the occasional paracetamol after a few days, and that was it. That is extremely unusual.”
Following the successful surgery, Alfie is now “running around as normal” and enjoying activities like basketball. “I can just tower over them now… I like doing basketball a lot,” he said. Alder Hey has since performed the same procedure on three other children with fibular hemimelia, and other centres across the country are preparing to adopt the technique.
