1. A plate for securing bones together, comprising: an elongate spine comprising at least one groove spanning along a length of the spine parallel to a central axis of the spine, wherein: a first surface of the spine comprises a thickened ridge spanning along a length of the spine parallel to the central axis of the spine; anda second surface, opposite the first surface, comprises the at least one groove; anda plurality of arms extending laterally from the spine, the plurality of arms comprising at least one arm on a first side of the spine and at least one arm on a second side of the spine. 2. The plate of claim 1, wherein the at least one arm on the first side of the spine and the at least one arm on the second side of the spine each comprise an attachment point for attaching the arms to a bone. 3. The plate of claim 2, wherein the attachment point comprises a screw hole defined by an inner surface configured to engage the head of one of a plurality of bone screws. 4. The plate of claim 2, wherein the attachment point comprises a threaded screw hole defined by a threaded inner surface configured to lockably engage one of a plurality of locking bone screws. 5. The plate of claim 2, wherein the at least one arm on the first side of the spine and the at least one arm on the second side of the spine each comprise a rigid rounded tab extending laterally from the spine perpendicular to the central axis of the spine. 6. The plate of claim 1, wherein: the thickened ridge comprises generally smooth, elevated ridge of material symmetrically distributed about the central axis of the spine spanning from the first end of the spine to the second end of the spine, the thickened ridge being thickest in the center of the spine and tapering off in thickness as the thickened ridge extends laterally toward the plurality of arms; andthe at least one groove comprises a pair of recessed channels symmetrically distributed about the central axis of the spine spanning from the first end of the spine to the second end of the spine. 7. The plate of claim 1, wherein the plate comprises a cross-sectional curvature in a plane perpendicular to the central axis. 8. The plate of claim 7, wherein compression of the at least one groove draws the at least one arm on the first side of the spine toward the at least one screw hole on the second side of the spine and increases the cross-sectional curvature of the spine. 9. The plate of claim 1, wherein compression of the at least one groove increases the axial stiffness of the plate along the central axis of the plate. 10. A plate for securing bones together, comprising: an elongate spine comprising: a thickened ridge, spanning along a length of the spine parallel to the central axis of the spine;a first surface of the spine comprising at least one groove spanning along a length of the spine parallel to the central axis of the spine; anda second surface, opposite the first surface, comprising the thickened ridge; anda plurality of arms extending laterally from the spine, the plurality of arms comprising at least one arm on a first side of the spine and at least one arm on a second side of the spine;wherein at least one of the at least one arm on the first side of the spine and at least one of the at least one arm on the second side of the spine each comprises an attachment point for attaching the arms to a bone, the attachment point comprising a hole defined by an inner surface configured to receive an attachment device. 11. The plate of claim 10, wherein the hole comprises a threaded screw hole defined by a threaded inner surface configured to lockably engage one of a plurality of locking bone screws. 12. The plate of claim 10, wherein: the thickened ridge comprises generally smooth, elevated ridge of material symmetrically distributed about the central axis of the spine spanning from the first end of the spine to the second end of the spine, the thickened ridge being thickest in the center of the spine and tapering off in thickness as the thickened ridge extends laterally toward the plurality of arms; andthe at least one groove comprises a pair of recessed channels symmetrically distributed about the central axis of the spine spanning from the first end of the spine to the second end of the spine. 13. The plate of claim 10, wherein the plate comprises a memory shape material operable to compress the at least one groove when the plate is heated above a transformation temperature of the memory shape material. 14. The plate of claim 10, further comprising one or more screw holes disposed along the spine. 15. The plate of claim 10, wherein the spine is curved along the central axis to approximate the geometry of a joint structure. 16. A method for securing bones together, comprising: attaching to a first bone and a second bone, a plate comprising:an elongate spine comprising at least one groove spanning along a length of the spine parallel to a central axis of the spine, wherein: a first surface of the spine comprises a thickened ridge spanning along a length of the spine parallel to the central axis of the spine; anda second surface, opposite the first surface, comprises the at least one groove; anda plurality of arms extending laterally from the spine, the plurality of arms comprising at least one arm on a first side of the spine and at least one arm on a second side of the spine. 17. The method of claim 16, wherein: the at least one arm on the first side of the spine and the at least one arm on the second side of the spine each comprise an attachment point, the attachment point comprising a screw hole defined by an inner surface configured to engage a head of a bone screw; andthe step of attaching comprises screwing the bone screw into the screw hole on the at least one arm on the first side of the spine or the at least one arm on the second side of the spine until the bone screw engages the threaded screw hole. 18. The method of claim 17, further comprising compressing the at least one groove to draw the at least one screw hole on the first side of the spine toward the at least one screw hole on the second side of the spine. 19. The method of claim 18, wherein the compressing step occurs after the attaching step. 20. The method of claim 18, wherein the compressing step occurs before the attaching step. 21. The method of claim 18, wherein the plate comprises a memory shape material operable to compress the at least one groove when the plate is heated above a transformation temperature of the memory shape material, and further comprising: mechanically deforming the plate such that the memory shape material is operable to compress the at least one groove once the plate is heated above the transformation temperature.
