Surgery restores paralysed hand
Quadriplegic US patient to regain some mobility after nerve transfer
For the first time, US surgeons have used a new type of operation called nerve transfer to restore hand function in a patient who was paralysed by a neck injury.
The surgery worked by taking a non-functional nerve that controls pinching the forefinger and thumb and plugging it into a functioning nerve in the man’s upper arm which had been used for bending his elbow.
After many months of intensive physical therapy, the 71-year-old patient − who was paralysed from the waist down and lost the use of his hands in a car accident − can now feed himself and even write with some assistance, according to the study in the Journal of Neurosurgery.
“This is not a particularly expensive or overly complex surgery,” said senior author Susan Mackinnon, who developed and performed the surgery.
The patient’s injury was in the lowest bone in his neck, known as the C7 vertebra.
For people who are injured higher up along the neck, from the C5 to C1 vertebra, such an operation would not likely be successful in restoring hand and arm function, doctors said.
“This procedure is unusual for treating quadriplegia because we do not attempt to go back into the spinal cord where the injury is,” said surgeon Ida Fox, assistant professor of plastic and reconstructive surgery at Washington University.
“Instead, we go out to where we know things work so that we can borrow nerves there and reroute them to give hand function.”
