(Free-Press-Release.com) November 28, 2011 -- Decompressive Laminectomy During Surgery

What happens during surgery?

There are seven steps of the procedure. The operation generally lasts 1 to 3 hours.

Step 1 : - Prepare the patient

You will lie on your back on the operative table and be given anesthesia. Once asleep you will be rolled over onto your stomach with your chest and sides supported by pillows. The area where the surgery is to be performed will be cleansed and prepped. If a fusion is planned and you have decided to use your own bone, the hip area will be cleansed and prepped to obtain a bone graft. If you’ve decided to use donor bone, a hip incision is unnecessary.

Step 2 : - Incision

A skin incision is made down the middle of your back over the appropriate vertebrae (Fig. 2). The length of the incision depends on how many laminectomies are to be performed. The strong back muscles are split down the middle and moved to either side exposing the lamina of each vertebra.

Step 3 : - Laminectomy or laminotomy

Once the bone is exposed, an X-ray is taken to verify the correct vertebra.

Laminectomy : - The surgeon removes the bony spinous process. Next, the bony lamina is removed with a drill or bone-biting tools. The thickened ligamentum flavum that connects the laminae of the vertebra below with the vertebra above is removed (Fig. 3). This is repeated for each affected vertebrae.

Laminotomy : - In some cases, the surgeon may not want to remove the entire protective bony lamina. A small opening of the lamina above and below the spinal nerve may be enough to relieve compression (Fig. 4). Laminotomy can be done on one side (unilateral) or both sides (bilateral) and on multiple vertebrae levels.

Step 4 : - Decompress the spinal cord

Once the lamina and ligamentum flavum are removed the protective covering of the spinal cord (dura mater) is visible. The surgeon can gently retract the protective sac of the spinal cord and nerve root to remove bone spurs and thickened ligament.

Step 5 : -

Decompress the spinal nerve The facet joints, which are directly over the nerve roots, may be undercut (trimmed) to give the nerve roots more room (Fig 5). Called a foraminotomy, this maneuver enlarges the neural foramen (where the spinal nerves exit the spinal canal). If a herniated disc is causing compression the surgeon will perform a discectomy.

Step 6 : - Fusion (if necessary)

If you have spinal instability or have laminectomies to multiple vertebrae, a fusion may be performed. Fusion is the joining of two vertebrae with a bone graft held together with hardware such as plates, rods, hooks, pedicle screws, or cages. The goal of the bone graft is to join the vertebrae above and below to form one solid piece of bone.There are several ways to create a fusion. The right one for you depends on your own choice and your doctor’s recommendation.
