Central lumbar spinal stenosis: natural history of non-surgical patients

Abstract

The natural history of LSS with moderate symptom levels rarely shows symptom deterioration over a median of 3.3 years; in fact, a slight improvement of symptoms was seen at group levels. The treatment decision was revised for 7%, and for the rest an increase in pain was seen in 10-13%. The results support reluctance towards surgery, if the symptom levels are tolerable for the patients.
