RT Journal Article SR Electronic T1 Lumbar canal stenosis: Start with nonsurgical therapy JF Cleveland Clinic Journal of Medicine JO Cleve Clin J Med FD Cleveland Clinic SP 909 OP 917 VO 69 IS 11 A1 Mazanec, Daniel J. A1 Podichetty, Vinod K. A1 Hsia, Augusto YR 2002 UL http://www.ccjm.org/content/69/11/909.abstract AB Although surgery is widely viewed as the definitive therapy for lumbar spinal stenosis, no randomized trials have compared surgical vs medical treatment. One study found that 60% of surgically treated patients improved, compared with 30% of those treated nonsurgically. We believe an initial nonsurgical approach is advisable for most patients.
