Introduction Painful lumbar spinal disorders represent a leading cause of disability in the US and worldwide. Interventional treatments for lumbar disorders are an effective treatment for the pain and disability from low back pain. Although many established and emerging interventional procedures are currently available, there exists a need for a defined guideline for their appropriateness, effectiveness, and safety. Objective The ASPN Back Guideline was developed to provide clinicians the most comprehensive review of interventional treatments for lower back disorders. Clinicians should utilize the ASPN Back Guideline to evaluate the quality of the literature, safety, and efficacy of interventional treatments for lower back disorders. Methods The American Society of Pain and Neuroscience (ASPN) identified an educational need for a comprehensive clinical guideline to provide evidence-based recommendations. Experts from the fields of Anesthesiology, Physiatry, Neurology, Neurosurgery, Radiology, and Pain Psychology developed the ASPN Back Guideline. The world literature in English was searched using Medline, EMBASE, Cochrane CENTRAL, BioMed Central, Web of Science, Google Scholar, PubMed, Current Contents Connect, Scopus, and meeting abstracts to identify and compile the evidence (per section) for back-related pain. Search words were selected based upon the section represented. Identified peer-reviewed literature was critiqued using United States Preventive Services Task Force (USPSTF) criteria and consensus points are presented. Results After a comprehensive review and analysis of the available evidence, the ASPN Back Guideline group was able to rate the literature and provide therapy grades to each of the most commonly available interventional treatments for low back pain. Conclusion The ASPN Back Guideline represents the first comprehensive analysis and grading of the existing and emerging interventional treatments available for low back pain. This will be a living document which will be periodically updated to the current standard of care based on the available evidence within peer-reviewed literature.

“…A multicenter RCT with 122 patients compared ISF with decompression to decompression alone. 103 Two-year follow-up was performed for patients with moderate-to-severe spinal stenosis. The primary endpoint included a composite of four measures: ODI, secondary surgery or injections, neurological status, and adverse events related to the procedure or device.…”

Introduction Lumbar spinal stenosis (LSS) is a common spinal disease of aging with a growing patient population, paralleling population growth. Minimally invasive treatments are evolving, and the use of these techniques needs guidance to provide the optimal patient safety and efficacy outcomes. Methods The American Society of Pain and Neuroscience (ASPN) identified an educational need for guidance on the prudent use of the innovative minimally invasive surgical therapies for the treatment of symptomatic LSS. The executive board nominated experts spanning anesthesiology, physiatry, orthopedic surgery, and neurosurgery based on expertise, publications, research, diversity and field of practice. Evidence was reviewed, graded using the United States Preventive Services Task Force (USPSTF) criteria for evidence and recommendation strength and grade, and expert opinion was added to make consensus points for best practice. Results The world literature in English was searched using Medline, EMBASE, Cochrane CENTRAL, BioMed Central, Web of Science, Google Scholar, PubMed, Current Contents Connect, Scopus, and meeting abstracts to identify and compile the evidence (per section) for LSS-related pain. Search words were selected based upon the section represented. Identified peer-reviewed literature was critiqued using USPSTF criteria and consensus points are presented. Discussion The algorithm for patient selection in the management of symptomatic spinal stenosis is evolving. Careful consideration of patient selection and anatomic architecture variance is critical for improved outcomes and patient safety. Conclusion ASPN created a guidance for best practice for minimally invasive surgical treatment of symptomatic spinal stenosis.

“…In recent years there is increased use of PMIF to treat lumbar spinal stenosis, foraminal stenosis, and mild to moderate lumbar disc protrusion, with good outcomes [8][9][10][11][12]. The success is attributed to inter-spinal distraction resulting in stretching the in-buckled ligamentum flavum, the opening of the neural foramina, and the reduction of intradiscal and interafacetal pressure.…”

“…Posterior midline interspinal fixation (PMIF) is a procedure that is gaining acceptance in the last 15 years [8][9][10][11][12]. It is primarily used for treating radicular pain and neurogenic claudication due to mild to moderate disc bulge, mild to moderate spinal stenosis, and foraminal narrowing.…”

Posterior Midline Interspinal Fixation (PMIF) to Treat Persistent Severe Pain Due to Severe Compression Fracture of Thoracic Vertebral Body: A Case Report

Generally, severe persistent pain due to compression fractures of the lumbar and thoracic vertebral bodies in the elderly, that fail conservative measures are treated with vertebroplasty or kyphoplasty. However, in the case reported in this paper, the compression fracture was so severe, that accurate bone needle placement into the vertebral body was felt to be difficult. In addition, there was a high risk of extravasation of the cement into the surrounding structures or blow-up of the lateral wall of the vertebral body. Therefore, a simple operation of posterior midline interspinal fixation (PMIF) was performed.The patient was a 91-year-old lady with severe pain in the mid-thoracic spine due to a severe compression fracture of the seventh thoracic vertebral body that was totally flattened in its anterior part. The patient was neurologically intact. However, she had difficulty walking, because the pain was very severe in an upright position. She was treated with a back brace and oxycodone for six weeks without any benefit.Because she was a poor candidate for vertebroplasty or kyphoplasty, a PMIF system was implanted. Postoperatively, within two weeks, her pain score dropped from 9/10 to 0/10; and from two months onwards she was completely free of pain medications until her death from an unrelated cause, 18 months after the operation. This is the first reported case of PMIF for the treatment of pain due to vertebral body compression fracture in the elderly. PMIF is a simple minimally invasive procedure without compromising the facet or any bony structure. The risk of severe complications, therefore, is remote. The success in this single case, therefore, begs for further exploration of this method in the treatment of compression fractures in the elderly.
