    摘要: A spinal implant adapted to be inserted into an interspinous space between adjacent spinous processes includes a proximal section, a central section, and a distal section disposed sequentially along a longitudinal axis. The distal section has feature(s) that allow the implant to be inserted laterally into the interspinous space, such as an approximately helical groove and/or a thread-like structure. The distal tip of the implant tapers inwardly, and may be rounded. The proximal section may include an outwardly extending wing or flange. The implant may include a main body that includes the wing or flange and a spacer slidably mated to the main body through the wing or flange.

    摘要: An embodiment of a system in accordance with the present invention can include an implant having a spacer with a thickness and a wing, wherein a first configuration of the wing has a first height substantially similar to the thickness and wherein the wing is adapted to be selectably arranged in a second configuration such that the wing has a second height greater than the first height. A periphery of the implant has a shape generally conformal with a shape of an inner surface of a cannula and a cross-sectional diameter smaller than an inner diameter of the cannula. The cannula is inserted such that a proximal end of the cannula is arranged between the adjacent spinous processes. The implant is then urged into position between the adjacent spinous processes by way of the cannula, and subsequently arranged in a second configuration to fix the implant in position.
