Interspinous devices are a recent treatment option. These devices can be implanted with local anesthesia and without the need to remove bone or soft tissue. According to the AAOS, they pose no serious risk and are more effective than epidural steroid injections, with a 60 percent to 70 percent success rate at 4 years after implantation.
Spinal stenosis surgery
Three to six months of nonsurgical care is standard for the lumbar spinal stenosis prior to surgical intervention. However, if a patient has numbness or weakness that interferes with walking, impaired bowel or bladder function, or other neurological involvement, surgery may be required immediately. An operation can relieve pressure on the spinal cord or nerves and restore and maintain alignment and strength of the spine. This release can be done by removing, trimming, or adjusting diseased parts that are causing the pressure or loss of alignment.
The most common spinal stenosis surgery is a minimally invasive procedure called decompressive laminectomy, which involves removal of the lamina (roof) of one or more vertebrae to create more space for the nerves. A surgeon may perform a laminectomy with or without fusing vertebrae or removing part of a disc.
What causes spinal stenosis?
Age and heredity are the primary culprits. Degenerative changes in spinal discs as we age can cause progressive narrowing of the space reserved for the spinal cord and other nerves. The tapering is usually preceded by more common conditions such as bone spurs, disc herniations, bulges, and tears, or scarring from previous treatments. Osteoarthritis, scoliosis, and rheumatoid arthritis are other factors, as well as birth defects that result in a spinal canal that’s smaller than average. “Early diagnosis and treatment is critical,” says Kaixuan Liu MD, PhD, founder of Atlantic Spine Center in Edison, N.J. “If symptoms are ignored, the condition will create more inflammation, which can cause permanent and irreparable nerve damage.”
What are the symptoms of spinal stenosis?
Symptoms can include pain in the neck or back, numbness, weakness or pain, tingling arms or legs, and foot problems. Lumbar spine stenosis patients rarely complain solely of back pain; their most common complaint is buttock and leg pain.
Non-surgical spinal stenosis treatment
Non-steroid anti-inflammatory drugs (NSAIDs) and muscle relaxants may be prescribed for several weeks. Physical therapy and specific exercises can also prove beneficial. “It’s a natural response to reaction to back pain to want to lie down and limit activity,” says Dr. Liu. “However, exercises can improve strength, flexibility, and range of motion, as well as reduce pain.” According to the American Academy of Orthopedic Surgeons, (AAOS), 15 percent of patients eventually improve with nonsurgical modalities; however, 70 percent continue to experience problems that may require surgical intervention.
