Interpretation of Best Practices for Minimally Invasive Lumbar Spinal Stenosis Treatment 2.0 (MIST) : Consensus Guidance from the American Society of Pain and Neuroscience (ASPN) in 2022

Lumbar spinal stenosis (LSS) is a common disease in orthopedics. The American Society of Pain and Neuroscience (ASPN) published a new version of minimally invasive treatment practice guidelines in 2022 to improve the clinical efficacy of LSS. A total of seven treatments for LSS were included in the guidelines, including percutaneous image-guided lumbar decompression (PILD), interspinous spacers (ISP), interspinous fusion (ISF), intrathecal drug delivery systems (IDDS), spinal cord stimulation (SCS), epidural steroid injections (ESI) and open decompression. Based on the guidelines, this paper summarizes and discusses the research progress of minimally invasive treatment of LSS in the context of the clinical situation, aiming to provide a reference for clinicians and further related researches.
