The Spinous Process Device was designed for the treatment of adjacent segment disease as an adjunct to fusion following an initial fusion and/or decompression procedure where the existing pedicle screw and rod construct may remain intact. Additionally, this novel device may be employed in cases both with and without intact spinous processes where most inter-spinous spacers cannot be utilized.
Spinal fusion surgery is currently the state of the art in treating of variety of pathologies and maladaptation relating to the lumbar region of the spine that have not responded well to rehabilitative therapies. Fusion almost always involves the use of implantable constructs that facilitate calcification between adjacent levels of the spine. While there have been tremendous advances in the technology associated with these implantable constructs, studies indicate that approximately 43% of lumbar fusion patients develop adjacent segment disease (ASD), often requiring fusion of the adjacent level as well. Current revision surgery used to treat ASD usually involves the removal of the existing pedicle screw-rod construct, followed by the installation of a new construct that secures the previously fused segments as well as the diseased adjacent segment. Although this procedure is effective at treating ASD, it is highly invasive. To address these issues, inter-spinous spacer devices have been developed. These devices represent a much less invasive treatment option, but they also require intact spinous processes on both the diseased segment, as well as the adjacent fused segment. Unfortunately, initial fusion procedures are often accompanied by laminectomy, or removal of the inferior spinous processes belonging to the fused segments, for the purposes of spinal decompression or the addition of lateral cross bars. The spinous process device developed by Mercy Research is the first-ever product indicated for treatment of ASD that does not require an intact spinous process on the fused segment. This device therefore addresses a clear gap in treatment options available for sufferers of ASD.
