摘要:A spinal implant for treating lumbar spinal stenosis or as an adjunct to spinal fusion. The implant includes a body portion having an interior cavity. A plurality of locking wings are adapted and configured to move between a stowed position retracted within the interior cavity of the body portion and a deployed position extended from the interior cavity of the body portion. In the deployed position, the wings fix the implant in a selected interspinous space. A cable and wheel arrangement moves the plurality of locking wings from the stowed position to the deployed position and a ratchet/pawl assembly prevents backward movement of the wings.
