Abstract: Lumbar spinal stenosis is one of the most common causes of low back and leg pain. To standardize the diagnosis and treatment of lumbar spinal stenosis with a combination of traditional Chinese and Western medicine，this guideline strictly followed the relevant guiding principles for the development of guidelines both domestically and internationally. A multidisciplinary working group was established. We adopted the GRADE approach to grade the quality of evidence and the strength of recommendation. Finally recommendations on the treatment of lumbar spinal stenosis with integrated traditional Chinese and Western medicine were formed，aiming to standardize clinical practice.
