Imagine this: A 20-year-old holds a small, round device against his leg. With the press of a button, electricity flows invisibly through his skin, powering a tiny motor inside a metal rod implanted in his femur. Slowly, his leg lengthens — no pins, no screws, no risk of infection.
This is no sci-fi story. That young man is Vincent. For most of his life, he walked with a visible difference: His right leg was 15 centimeters shorter than his left. Born in Trois-Rivières, Québec, Canada, he grew up wearing shoes with thick compensating soles just to walk properly.
“Doctors told me there was nothing they could do,” he recalled.
That changed last June, when Vincent became the first patient in Canada to receive the wireless metal rod at Shriners Hospitals for Children Canada. The surgery, performed by orthopedic surgeon Mitchell Bernstein, M.D., marked his third major operation to adjust his leg length – but this time, the rod’s motorized, wireless design meant a faster, safer and less painful recovery than ever before.
Three times a day, Vincent places the external device against his skin at a precise location. An electrical pulse activates the motor inside the rod, gradually lengthening his leg and stimulating new bone growth.
“It’s like charging a cellphone or a wireless watch,” Dr. Bernstein said. “Once the connection is made, electricity powers the motor inside the rod, and it extends.”
Unlike traditional limb-lengthening surgeries, which rely on external fixators held in place by screws or pins that protrude through the skin, the wireless system eliminates one of the biggest risks: infection.
“We’ve eliminated infections related to external pins because nothing comes out of the skin,” Dr. Bernstein said. “This technology is a game changer.”
A college student who hopes to become an electrician, Vincent said the wireless implant was far less painful and restrictive than the external fixators he experienced with previous surgeries.
Since the operation, Vincent’s right leg has lengthened by 4.5 centimeters, adding to previous gains achieved by surgery.
For Vincent, the implant has been life changing. “I’ll be able to learn how to skate,” he said, smiling. “I never thought I’d be able to do that in my life.”
After years of orthopedic procedures, Vincent is finally nearing the end of his medical journey. The remaining difference between his legs is now minimal, and he no longer needs shoe inserts. Doctors expect that the metal rod can be removed next summer.
“It’s a big investment,” Vincent said, “but it’s going to change my life.”
He’s already thinking ahead — skating first, jogging next.
