A spacer device that is to be inserted between the spinous process of adjacent vertebrae. In one embodiment, the spacer device is percutaneously inserted between the spinous process of adjacent vertebrae using minimally invasive surgical procedures. The spacer device includes a body portion having a channel extending therethrough, a plate member attached at one end of the body portion that is larger cross-wise than the body portion, and at least one retaining member attached proximate to an opposite end of the body portion from the plate member. The spacer device is inserted between the spinous process with the retaining member stored within the body portion. A deploying device is inserted into the channel to deploy the retaining member to lock the spacer device in place.
