World’s first self-powered spinal implant transmits healing data from inside the body

  1. Each year, nearly a million Americans undergo spinal fusion surgery. The procedure fuses two vertebrae using a metal cage and bone graft, held together by screws and brackets. Recovery monitoring still relies on X-rays and patient symptoms.

    “After implanting the hardware, we monitor it using X-rays and symptoms presented by the patient,” said Agarwal, co-principal investigator and associate professor in the Department of Neurological Surgery.

    “This means patients have to make in-person visits and subject themselves to radiation.”

    Since the healing process is hard to monitor continuously, Agarwal said it’s not a connected healthcare experience. Although implantable wireless devices exist, they depend on batteries and electronics, limiting their longevity.
