The spine is made of bones (vertebrae) separated by soft cushions (intervertebral disks).
Lumbar (lower back) spine disease is usually caused by herniated intervertebral disks, abnormal growth of bony processes on the vertebral bodies (osteophytes), which compress spinal nerves, trauma, and narrowing (stenosis) of the spinal column around the spinal cord.
Symptoms of lumbar spine problems include:
The surgery is done while the patient is deep asleep and pain-free (general anesthesia). An incision is made over the lower back, in the midline.
The bone that curves around and covers the spinal cord (lamina) is removed (laminectomy) and the tissue that is causing pressure on the nerve or spinal cord is removed. The hole through which the nerve passes can be enlarged to prevent further pressure on the nerve. Sometimes, a piece of bone (bone graft), interbody cages, or pedicle screws may be used to strengthen the area of surgery.
Patients usually require physical therapy to optimize spinal mobility after lumbar spine surgery. Results are variable depending on the disease treated.
