<p>An unloading dynamic intervertebral device comprising a first bar and a second bar configured for providing an even, steady and adjustable decompression of the intervertebral interspinous space and for maintaining the distance between at least two vertebrae. The first bar may comprise a guideline with an elongated gap formed therein. The second bar may comprise a guide having at least one tang interposed within the elongated gap of the first bar, such that the first bar and the second bar are rotationally and slidably connected with each other about the tang. An end of the first bar and an opposing end of the second bar may comprise shaped bearings configured for bony elements of the spine. The first and second bar may be movable relative to each other between an open position and a closed position.</p> |
