Emerging literature supports the use of basivertebral nerve ablation (BVNA) for a specific cohort of patients with chronic low back pain and Type 1 or Type 2 Modic changes from vertebral levels L3-S1. The early literature warrants further evaluation. Studies establishing the efficacy of BVNA use highly selective patient criteria. ⋯ The population which may benefit from BVNA is small. Our study demonstrated that over a year, the prevalence for BVNA candidacy using the foundational studies criteria was 3% (95% CI 1% - 5%). While physicians may be tempted to use less stringent selection criteria in practice, upon doing so they cannot cite the foundational studies as evidence for the outcomes they expect to achieve. Those outcomes will require more studies which formally assess the benefits of BVNA when selection criteria are relaxed.

Randomized Controlled Trial
Efficacy and safety assessment of orthopedic device (LSM-01) for low back pain: A randomized, single-blinded, sham-controlled, parallel-group, pilot clinical trial.
Low back pain refers to pain that occurs mainly in lumbosacral spine, and is a clinically common symptom that 70% to 90% of people experience at least once during their lives. ⋯ LSM-01 can be effective in improving pain of low back pain. A future large-scale main trial will be conducted based on this pilot study results.

ReviewSystemic corticosteroids for radicular and non-radicular low back pain.
Corticosteroids are medications with anti-inflammatory and immunosuppressant properties. Systemic corticosteroids administered through the oral, intravenous, or intramuscular routes have been used to treat various types of low back pain, including radicular back pain (not due to spinal stenosis), non-radicular back pain, and spinal stenosis. However, there is uncertainty about the benefits and harms of systemic corticosteroids for low back pain. ⋯ Systemic corticosteroids appear to be slightly effective at improving short-term pain and function in people with radicular low back pain not due to spinal stenosis, and might slightly improve long-term function. The effects of systemic corticosteroids in people with non-radicular low back pain are unclear and systemic corticosteroids are probably ineffective for spinal stenosis. A single dose or short course of systemic corticosteroids for low back pain does not appear to cause serious harms, but evidence is limited.

Case Reports
Botulinum toxin injection strategy of intractable and relapsed piriformis syndrome: A case report.
Piriformis syndrome (PS) is neuromuscular disorder caused by sciatic nerve compression by piriformis muscle and related to sciatic-type pain. When the conservative care fails, local injection or surgery can be also performed into piriformis. In recent years, botulinum toxin (BoNT) has also been considered as a new therapeutic option of piriformis syndrome. ⋯ We report a case of treating relapsed piriformis syndrome with BoNT injection of different dilution volume, suggesting that the higher the dilution volume, the more effective for therapeutic effect of BoNT.
