Posterior Lumbar Fusion

Lumbar surgery dfw

Posterior lumbar fusion, also known as arthrodesis, is a surgical procedure performed to join two or more of the lumbar vertebrae (the small bones of the lower back) into one solid bone. This operation is designed to stop mechanical pain, the pain associated with the movement of the affected bones that results in inflammation of the discs and joints. During this surgery, a bone graft is inserted along the side of the vertebrae which will eventually help the bones grow together. The procedure is called a posterior fusion because the surgeon works on the back of the spine.

Reasons for Posterior Lumbar Fusion

Posterior lumbar fusion is commonly performed to treat a variety of spinal conditions affecting the lower back, including:

  • Spondylolisthesis
  • Spinal fractures
  • Tumors
  • Infections
  • Scoliosis
  • Degenerative disc disease
  • Radicular pain (down the buttock and thigh)

Other surgical procedures are frequently performed along with lumbar fusion, such as removing bone spurs or repairing herniated discs.

The Posterior Lumbar Surgery DFW Fusion Procedure

During the procedure, performed under general anesthesia, the patient is usually face down on a special operating table. This position not only provides the surgeon with room to operate and increases comfort for the patient, but also lessens the patient's blood loss.

An incision is made in the middle of the lower back to expose the spinal column, and part of the lamina, the bony covering of the spinal canal, is removed. The surgeon also removes any disc fragments or bone spurs impinging on the nerves, and prepares the patient for the fusion by shaving off a layer of bone from the back of the affected vertebrae. This resulting cut surface is receptive to the bone graft that will be attached.

Because the primary goal of a posterior lumbar fusion is to eliminate the mechanical pain and inflammation associated with vertebral movement, the operation basically consists of a type of welding, in which the bone graft, taken either from the patient's own hip (autograft), harvested from a cadaver (allograft) or manufactured (synthetic), is used to stimulate bone growth. Most often, the graft is fixed in place using a combination of screws, rods and plates to keep the vertebrae from moving. Held in place this way, the tissues have a higher success rate of growing together completely and permanently.

Recovery from Posterior Lumber Fusion

Recovery from this surgery takes from 1 to 3 months during which the patient normally undergoes physical rehabilitation and must avoid heavy lifting, bending and twisting.
