Patients with severe lower back pain due to narrowed passages for spinal nerves obtained sustained significant relief with a new, minimally invasive procedure, a new study shows.[1]
The new procedure uses a flexible rasp-like device to remove bone and tissue to enlarge the opening, called the foramen, where nerves exit the spinal canal and extend to the limbs. The new device, called iO-Flex® allows the surgeon to remove just enough bone to open up the passageway and take the pressure off the nerve without removing so much bone that the spine becomes unstable.
