The ILIF Procedure (Interlaminar Lumbar Instrumented Fusion) was developed to overcome the potential shortcomings of standard lumbar spinal stenosis treatments (. decompression alone and decompression with fusion), using a minimally disruptive surgical technique. Lumbar spinal stenosis is a gradual narrowing of the space where nerves pass through the spine, which can be a result of aging and “wear and tear” on the spine from everyday activities and/or resultant positional changes of the vertebrae. The most common surgical treatment for lumbar spinal stenosis is a procedure called a decompression, which involves removing bone or ligaments that are pressing on the spinal cord and/or nerves.
The ILIF procedure involves a minimally disruptive decompression procedure called a laminotomy, which involves temporary distraction (opening up) of the space between the spinous processes, and careful removal of only small sections of bone to release the pressure on the spinal cord and nerves.
How is the lumbar sympathetic block performed?
It is done with the patient lying on stomach. The patients are monitored with EKG, blood pressure cuff and an oxygen-monitoring device. Temperature sensing probes may also be placed on your feet. The lumbar sympathetic block is performed under sterile conditions. The skin on back is cleaned with antiseptic solution and the skin is then numbed with a local anesthetic. Then X-ray is used to guide the needle or needles into the proper position along the outside of the spine. Once in place, a test dose of dye is used to confirm that the injected medication will spread in an appropriate area. If this is okay, the injection takes place gradually over several minutes. The physician will use the X-ray to evaluate the spread of the injected medication. When a sufficient area is covered, the injection will be over. When done, the needle is removed and a Band Aid is applied.
