1. A lumbar process stabilization device for a spine for use in a static configuration or a dynamic configuration, comprising:
an upper arm, including a first side portion and a second side portion in a shape of a stirrup, wherein the stirrup defines an upper cavity that is configured to receive a first spinous process of the spine, and wherein either or both of the first side portion and the second side portion of the upper arm defines one or more openings;
an upper set of one or more screws that are configured to extend through the one or more openings of the first side portion and the second side portion of the upper arm and, in use, into the first spinous process received in the upper cavity;
a lower arm, including a first side portion and a second side portion in a shape of a stirrup, wherein the stirrup defines a lower cavity that is configured to receive a second spinous process of the spine, and wherein either or both of the first side portion and the second side portion of the lower arm defines one or more openings; and
a lower set of one or more screws that are configured to extend through the one or more openings of the first side portion and the second side portion of the lower arm and, in use, into the second spinous process received in the lower cavity;
wherein the lower arm is connected to the upper arm at a pivot connection;
wherein, in the static configuration, the upper arm and the lower arm are secured in a fixed orientation
wherein, in the dynamic configuration, the upper arm and the lower arm can move relative to one another about the pivot connection; and
wherein at least one of the upper arm and the lower arm includes a base and a brace, wherein the brace includes the first side portion and the second side portion which are in the shape of the stirrup, and wherein the brace is configured for movement with respect to the base, such movement allowing for adjustment of an overall length of the device, thereby allowing the device to span one or more vertebrae interspaces of the spine and to compress or distract across a space between the first spinous process to which the upper arm is secured and the second spinous process to which the lower arm is secured.
