Some of the symptoms include weakness in the legs or pain in the back and/or legs when walking, often either resulting in a hunched-over walk, or made better when leaning forward. There can be impairment of bladder or bowel function with either incontinence or retention. Another potential sign or symptom of lumbar spinal stenosis is pain in the legs, such as a sharp, burning, or electrical pain, which can go up or down the back, or legs.
This condition can be caused by variations of osteoarthritis (arthritis), injuries and instability in the neck, herniated disks, circumstances where someone is born with a small spinal canal, as well as many other causes.
The treatment of symptomatic lumbar stenosis that has progressed in spite of conservative management (ie, less than surgery) is usually dependent upon the severity of the stenosis, whether there is associated spinal deformity, and what is the cause of the stenosis, but can include anterior procedures (such as anterior or lateral fusions, done open or minimally invasively), and posterior procedures in the back (such as laminectomy, with or without fusion, laminoplasty, or minimally invasive treatments, when appropriate).
