Abstract
Systems and methods are disclosed for maintaining spacing between a superior spinous process and a superior lamina, and an inferior spinous process and an inferior lamina of adjacent vertebrae of a spine. A system may include an implant having a proximal superior surface with a superior concavity shaped to receive the superior spinous process, a proximal inferior surface with an inferior concavity shaped to receive the inferior spinous process, a distal superior surface, distal to the proximal superior surface, that faces the superior lamina, and a distal inferior surface, distal to the proximal inferior surface, that faces the inferior lamina. The implant may further have a threaded member extending along a proximal-distal direction, that rotates to urge the implant to move from a retracted configuration to a deployed configuration by urging the distal superior surface and the distal inferior surface to move apart.
