Spinal fusion is surgery to correct problems in the spine bones (vertebrae). The surgery
  stabilizes the back by permanently placing certain bones in the spine together.
    
  Fusing means two bones are   permanently placed together so that movement between them can no longer   occur.
    
  Spinal fusion is usually done   along with other surgical procedures of the spine, such as a diskectomy.
    
    Description
    
  Spinal fusion surgery uses bone   grafts, with or without screws, plates, cages, or other devices. The   bone grafts are placed around the problem area of the spine during   surgery. As the body heals itself, the graft helps join the bones   together.
  The most common spinal area   treated is the lower (lumbar) spine. However, it can also be done on the   upper (cervical) spine.
    
  The procedure is performed while   you are under general anesthesia (unconscious and pain-free). The   surgeon makes a cut over the area of the spine that will be treated.
    
  If you are having a problem in   the lower spine corrected, the repair is done through a surgical cut   made directly over the spine. This is called the posterior lumbar   approach.
    
  If you are having a problem in   the upper spine corrected, the repair is usually done through a surgical   cut in the front or side of the neck (Anterior Cervical spine).  
    
  If you are having a problem in   the middle spine corrected, the repair is sometimes done through a   surgical cut in the chest and abdomen (anterior thoracic spine).
    
  Depending on the reason for   surgery, the procedure may involve a combination of surgical cuts.
    
     Why this is done
    
  Spinal fusion may be recommended for:
    
    
 Abnormal curvatures, such as those seen with Scoliosis or kyphosis
    Abnormal curvatures, such as those seen with Scoliosis or kyphosis Injury or fractures to the bones in the spine
    Injury or fractures to the bones in the spine Herniated disk
    Herniated disk Spinal stenosis
    Spinal stenosis Weak or unstable spine caused by infections or tumors
    Weak or unstable spine caused by infections or tumorsIf the pain is persistent and does not respond to other treatments, surgery is considered to relieve the pressure on the nerves.Surgery is also performed for muscle weakness that does not improve or is getting worse, and for patients having bladder or bowel problems.
