Imagine if the branches of a tree were just as big at the top as they are at the bottom, and that sometimes, heavy loads were placed on the ends of the very highest branches. Think of the stress that would put on the lower portion of the tree trunk. Well, that’s analogous to the situation we humans experience with our spinal columns. Our spinal column is like the trunk of a tree, but we’re just as big at the top of our trunks as at the bottom. The stress this puts on our lower backs – also called the lumbar region of the spine – is exacerbated by the cumulative affect of a lifetime of lifting and twisting in combination with degenerative changes of the spine that occur as a result of aging. So it’s not surprising that the majority of back problems that bring patients to spinal specialists are centered in the lower, or lumbar region of the spine.
These stresses, along with our genetic makeup, disease or injury, can result in a host of spinal disorders such as bulging or herniated discs, slipped disc and spinal stenosis. These disorders, in turn, can result in unnatural pressure being put on nerves that emanate from the spinal column, potentially causing pain, restricted mobility, and other symptoms of pinched nerves. We talked about the problem of pinched spinal nerve and spinal decompression in general in a previous blog. As we noted, spinal decompression is a means of easing pressure on impinged spinal nerves, and can be performed either non-surgically or surgically. Lumbar spinal decompression simply refers to decompression procedures performed on the lower portion of the spine.
The surgical solution for a lumbar pinched nerve involves removing tissue from vertebrae in the lumbar region that impinge, or put pressure on a nerve. This is called lumbar spinal decompression surgery. Historically, spinal fusion back surgery has been performed in conjunction with lumbar decompression surgery to stabilize the spine. Today, the TOPS™ (Total Posterior Spine) System provides an alternative to spinal fusion that preserves the full range of the spine’s natural motion, and has been shown to provide better outcomes than fusion in clinical studies performed around the world. This provides an important more treatment option for individuals with moderate to severe symptoms of pinched nerves who do not respond to non-surgical lumbar decompression procedures.
