PLIF stands for Posterior Lumbar Interbody Fusion is a type of spinal fusion surgery may be indicated for patients with severe back pain. As the name suggests, the operation will involve the lumbar spine or lower back area. People with diseases of the spine, as spondylolisthesis or degenerative disease of the vertebral disc or can benefit from this type of spinal fusion surgery. In PLIF, the main objective is the creation of actual merger or bone growth in the affected area of the spine using bone grafts made from human tissue or from synthetic materials. The following are some of the advantages of the approach PLIF over other types of surgeries spinal fusion:
The posterior approach used in PLIF or posterior lumbar interbody fusion basically means that the separation or intervertebral distraction readily available. On the back side, the vertebral bodies are much more exposed and facilitates alignment of the spine. Restoration of normal structure that is easy to reach the posterior lumbar level and that is why some medical experts choose PLIF when performing spinal fusion surgery. With the intervertebral separation easier, decompress neural pathways will also be easier.
PLIF also maximizes space for bone grafts to heal. This means that posterior interbody the surface area involved in making the lumbar surgery will be much larger compared to other approaches. In terms of bone growth and spinal fusion, a larger surface area is ideal for successful surgery. With a larger area, bone grafts that are put in place will also have a greater chance of cure and / or real growth and fusion.
Another benefit of making spinal fusion surgery through PLIF is easier restoration lordosis. Lordosis refers to the natural curvature of the spine in the lower back or lumbar and this can only be restored properly when spinal fusion is performed with the posterior approach.
The posterior approach in PLIF is also considered to be more effective in terms of maintaining proper alignment spine. Using the posterior spinal fusion approach will lead to the stability of the column with the correct alignment including the height of the disc space. This benefit also relates to the separation easier intervertebral PLIF offered by other techniques.
Posterior Lumbar Interbody Fusion also gives at least secondary sliding a technique called ligamentotaxis. In this technique, force is exerted on the bone parts to move together. With the later approach, the actual slip of bone parts can be prevented and / or better control.
The medical condition or spinal patients royal dictate the type of approach that surgeons use when spinal fusion surgery is done. For cases requiring emphasis in proper alignment and / or neurological decompression eg PLIF it has several benefits and advantages over other techniques spinal fusion. In all cases, all the pros and cons are seriously considered before any type of spinal fusion surgery to get the most benefits and avoid more complications.
