Abstract
Abstract The present invention is a device and method that immobilizes the vertebral bodies by immobilizing the respective spinous process extending therefrom. The device contains a spacer extending from a body with the spacer adapted to be positioned between adjacent spinous processes so that the spacer may be located close to the spine. A strap connected with the body is designed to engage the spinous processes, such that the device may be adjusted to be positioned about the spinous processes. The device ensures that the spacer remains positioned between adjacent spinous processes. The method to insert the device minimizes destruction to body tissue, thus it is less traumatic to the patient and allows for the patient to recover from the procedure faster than conventional methods.
