摘要：
Systems and method in accordance with an embodiment of the present invention can includes an implant comprising a spacer and a frame having a central body and a helical shaped wing extending from the central body. The frame can be positioned near about adjacent spinous processes, and can be rotated and urged so that the adjacent spinous processes pass within a groove of the wing, thereby allowing the wing to be arranged on an opposite side of the adjacent spinous processes. The spacer can then be arranged over the frame so that the spacer contacts and distracts the spinous processes, thereby limiting relative movement of the adjacent spinous processes during extension.
