Lumbar fusion neuro-spine surgery is a treatment procedure in which affected or injured lumbar vertebrae are fused together. When the vertebrae have been surgically stabilized, abnormal motion is stopped and function to the spinal nerves is restored.
Lumbar fusion surgery is performed in an attempt to:
Types of Fusion Surgeries
The type of fusion you will have is dependent on your symptoms and specific diagnosis. Talk with your neurosurgeon about the exact approach of your lumbar fusion surgery.
Lumbar Fusion with Instrumentation
Depending on the individual patient, a neurosurgeon can choose to also have metal rods, screws or hooks used in combination with the bone graft to further stabilize the spine.
For most neuro-spine fusion surgeries, patients are given general anesthesia to put them to sleep. A breathing tube may also be inserted to assist your lungs throughout the procedure.
Patients are placed on a special operating room bed that allows for optimal access to the spine and room for the surgeon to work and helps greatly reduce the potential for blood loss.
Your doctor will make a short incision in your back to expose the correct area of the spine. Depending on the type of fusion being performed, two incisions may need to be made, one on either side of the spine. An X-ray is used in the operating room to ensure that the correct bone/disc(s) is operated upon. Some neurosurgeons may also use a special surgical microscope during surgery to magnify the area they are operating upon.
Your neurosurgeon may use small cutting instruments to carefully remove soft tissue near the spinal nerves. Before fusion takes place, the surgeon removes all or part of the lamina bone, takes out any disc fragments and eliminates any nearby bone spurs (laminectomy). Next, your surgeon will remove the affected (vertebral) disc, which is the cushion between your vertebrae, as well as any arthritic areas. A bone graft is then placed between the vertebrae where the disc was originally. Eventually, this graft will fuse to the surrounding vertebrae to prevent abnormal motion of the area of the spine.
At this time, your neurosurgeon may choose to fix the bones in place with a single choice or combination of metal screws, rods and plates. A fusion with instrumentation (hardware) can hold the vertebrae in place while the bone graft fuses properly. The less motion there is between the healing bones, the higher the chance of successful fusion. Instrumentation has increased the success rate of spinal fusions considerably.
Once this is complete, the muscles and soft tissue is put back into place and the skin is closed with sutures, staples, skin glue or steri-strips (small pieces of tape).
Your length of lumbar fusion recovery time in the hospital will depend on the reason that you needed to have a lumbar fusion. Most patients go home1-2 days after surgery, but your neurosurgeon will decide when you are ready for discharge.
If you require some rehabilitation before going home, a doctor from the Physical Medicine and Rehabilitation department will see you and make specific recommendations regarding your discharge. You need to be able to walk, eat, urinate, and your surgical wound must be healing well.
