There is an association between cigarette smoking, back pain and chronic pain syndromes of all types. [45] [46] [39] [47] [48] In a report of 426 spinal surgery patients in Denmark, smoking was shown to have a negative effect on fusion and overall patient satisfaction, but no measurable influence on the functional outcome. [49]

The scar tissue may be located inside the knee joint or may involve the soft tissue structures around the knee joint, or both locations.

Spinal stenosis began to be recognized as an impairing condition in the 1950s and 1970s. Individuals who experience back pain and other symptoms are likely to have bigger spinal canals than those who are asymptomatic. [45] A normal-sized lumbar canal is rarely encountered in persons with either disc disease or those requiring a laminectomy. [31]
LSS may also be acquired from changes due to spinal surgery such as excess scar tissue or bone formation. [7] Other secondary causes include space-occupying lesions , ankylosing spondylitis , rheumatoid arthritis , and Paget's disease .
Spinal stenosis is an abnormal narrowing of the spinal canal or neural foramen that results in pressure on the spinal cord or nerve roots. [6] Symptoms may include pain, numbness, or weakness in the arms or legs. [1] Symptoms are typically gradual in onset and improve with leaning forward. [1]
After age 50 or 60, osteoarthritic degeneration (spondylosis) or spinal stenosis are more likely causes of low back pain or leg pain. 4.8% of males and 2.5% of females older than 35 experience sciatica during their lifetime. Of all individuals, 60% to 80% experience back pain during their lifetime. In 14%, pain lasts more than two weeks.
