The device may also have at least two retainers (14,16) positioned in and extendable from the body portion. A mechanism positionedwithin the body portion may be used to move the retainers between a retractedposition and a deployed position. When the retainers are in the deployedposition, the retainers may be positioned around the spinous process of atleast one of two adjacent vertebrae. A plurality of installation tools whichmay be used to install the device are also disclosed.
