Lumbar Fusion

In a lumbar fusion procedure, transplanted bone grows together with existing bone in the lumbar (lower back) region of the spinal column. It forms one solid bone to stabilize and restore strength to that section of the spine.

Advanced Minimally Invasive Lumbar Fusion

Our skilled neurosurgeons at Hunt Spine in Los Angeles perform lumbar fusion with the most advanced method with smaller incisions, a minimally invasive technique for a safer, quicker procedure with reduced post-operative pain and less downtime.

When Is Lumbar Fusion Needed?

Lumbar fusion may be appropriate when the lumbar region of the spine has become unstable. This can occur as the result of deformity, a tumor, trauma, or degeneration. It can also occur as a side effect of medical intervention to treat a tumor, a deformity, or a degenerated disc.

When the spine has become unstable because of medical treatment, this is known as iatrogenic instability. It may be necessary to surgically remove sections of the disc or bone in the lower back to reduce the pain and symptoms associated with a degenerated disc, a tumor, or a spinal deformity. As this can leave the spine structure less stable, lumbar fusion may be performed to restore strength and prevent or correct iatrogenic instability.

How Is Lumbar Fusion Performed?

Minimally invasive lumbar fusion may be performed using either of two common procedures:

Transforaminal interbody lumbar fusion (TLIF) in which the surgeon can achieve fusion in both the front and back of the spine in one procedure
Lateral lumbar interbody fusion (LLIF) in which the spine is approached from the side for the least disruption to muscles, bones, and organs

The procedure involves placing small incisions through which tubular dilators (tubes of expanding diameter) are inserted to create a tunnel through the tissues down to the spinal column. Tubular retractors are used to hold the tunnel open during the procedure.

The spine surgeon may use an endoscope (thin tube with a camera and light attached) to view the treatment area. Radiographic imaging may also be used to help guide the procedure.

Spinal fusion is performed through the retractor. The surgeon places a bone graft to create a bridge between the existing bones. The graft may come from a bone bank or from the patient’s own body, taken from the hip bone.

The surgeon may use a bone-promoting substance or other materials to aid bone growth or add volume to the bone graft. Screws, rods, or plates may be used to hold the bone in place. Finally, the surgeon removes the retractor and closes the incision.

Advantages of Minimally Invasive Lumbar Fusion

Lumbar fusion using minimally invasive techniques has a number of advantages over traditional open surgery, including:

Smaller incisions
Less blood loss
Reduced risk of infection
Less muscle and soft tissue damage
Reduced post-operative pain
Less need for medication
Faster recovery
