Lumbar Spinal Stenosis and Minimally Invasive Lumbar Decompression: A Narrative Review

Source— Journal of Pain Research Author— Hongjie Yuan, Xiaobin Yi Published November 6, 2023

This narrative review was designed to elucidate efficacy, safety profile, certain procedure details, advantages, and limitations of the mild® Procedure. All studies included in the review were clinical trials of mild®, including analytic and descriptive studies. The authors focused on indications, contraindications, VAS scores, ODI scores, effective rate, efficacy durations, and procedure details.

The publication describes mild® as an emerging minimally invasive procedure for lumbar spinal stenosis (LSS). A common pain disorder, LSS’s prevalence in adults increases with age and can present frustrating symptoms, possibly including persistent lumbar back pain, lower extremity pain, lower leg numbness, tingling, paresthesia, and difficulty walking. Typically, LSS patients cannot walk continuously and require intermittent resting while walking; this is termed neurogenic claudication.

According to the literature, the authors found that the VAS and ODI scores for mild® could be reduced from pre-treatment levels to post-treatment levels. A 2-year postoperative stability of efficacy was also supported, and one RCT study testified to the superior efficacy of mild® over epidural steroid injections (ESIs).

Based on the reviewed literature, the article concludes that mild® is a safe and effective procedure. It can reduce pain intensity and significantly improve functional status. This makes mild® a preferable option for LSS patients who did not find more conservative treatments to be successful but, according to this publication, does not make it the preferred choice for those who require immediate invasive decompression surgery.
