Definition A CSF leak is an escape of the fluid that surrounds the brain and spinal cord. Alternative Names Intracranial hypotension Causes, incidence, and risk factors Any tear or hole in the membrane that surrounds the brain and spinal cord (dura) can allow the fluid that surrounds those organs to leak. This fluid is called the cerebrospinal fluid (CSF). When it leaks out, the pressure around the brain and spinal cord drops. Causes of leakage through the dura include: Certain head, brain, or spinal surgeries Head injury Placement of tubes for epidural anesthesia or pain medications Spinal tap ( lumbar puncture ) Sometimes, no cause can be found. This is called a spontaneous CSF leak.
Lumbar spinal surgery is used to correct problems with the spinal bones (vertebrae), disks, or nerves of the lower back (lumbar spine).
Spinal surgery - cervical
Lumbar spinal surgery
The spine consists of bones (vertebrae) separated by soft cushions (disks). Pressure on the nerves that branch off the spinal cord can produce pain, numbness , tingling , or weakness.
Lumbar spinal surgery is done while you are under general anesthesia (unconscious and pain-free). A surgical cut is made over the area of the problem. The bone that curves around and covers the spinal cord and the tissue that presses on the nerve or spinal cord are removed.
The hole through which the nerve passes may be widened to prevent further pressure on the nerve. Sometimes, spinal fusion is necessary to stabilize the area.

Definition Spinal cord abscess is swelling and irritation (inflammation) and the collection of infected material (pus) around the spinal cord. Alternative Names Abscess - spinal cord Causes, incidence, and risk factors A spinal cord abscess is caused by an infection inside the spine. An abscess of the spinal cord itself is very rare. A spinal abscess usually occurs as an epidural abscess . Pus forms as a collection of: Destroyed tissue cells Fluid Live and dead bacteria and other microorganisms White blood cells The pus is commonly covered by a lining or membrane that forms around the edges. The pus collection causes pressure on the spinal cord. The infection is usually due to bacteria. Often it is caused by a staphylococcus infection that spreads through the spine. It may be caused by tuberculosis in some areas of the world, but it is not as common today as it was in the past. In rare cases, the infection may be due to a fungus. The following increase your risk of a spinal cord abscess: Back injuri...
