Cutting Through the Hype: Marijuana and CBD Oil for Pain (203)

In 2018, the United States opioid epidemic raged on with more than 45,000 overdose deaths. Several states have legalized medical or recreational marijuana, and all forms of cannabis products are being used for the treatment of pain. In many cases, patients and prescribers prefer using cannabis as an alternative to opioids, but the strength of the evidence for this is not widely understood. This session will provide learners with knowledge of the strength of evidence for using cannabis products for treatment of pain and opioid reduction as well as help learners gain an understanding of the acute and chronic risks of THC/CBD treatments.

CBD Oil for Pain?

Thomas Pittelkow

Cannabis to Reduce Opioid Use?

Mark Wallace

Learning Objectives:

  • Describe the biology of the endocannabinoid system and how exogenous cannabinoids are hypothesized to treat pain.
  • Assess the strength of peer-reviewed evidence for the use of cannabis and CBD oil for the treatment of pain.
  • Explain the risks and benefits of cannabis use for pain treatment.

Diagnostic and Prognostic Anesthetic Blocks for Facet, Sacroiliac, and Knee Joint Pain: An Evidence-Based Update (202)

This session discusses the evidence base for anesthetic nerve blocks as a tool to predict clinical outcomes following radiofrequency neurotomy for joint pain. The impact of nerve versus intra-articular block, number of blocks, anesthetic volume used, use of contrast agent, and variations in needle tip position will be reviewed.

Medial Branch Blocks: A Double-Edged Sword

Patricia Zheng

Lateral Branch Nerve Blocks: The Foundational Science and Elements yet to Be Defined

Byron Schneider

Genicular Nerve Blocks: Optimization for Accuracy and Inherent Limitations

Zachary McCormick

Learning Objectives:

  • Review the current diagnostic and clinical outcome literature that addresses medial branch nerve blocks in order to select patients for radiofrequency neurotomy in the treatment of refractory spinal pain of facet joint origin.
  • Describe the foundational literature that defined an anesthetic block paradigm of the lateral branch nerves in order to anesthetize the posterior sacroiliac joint/dorsal ligaments, and discuss the need for prognostic studies of lateral branch nerve blocks to determine if such blocks predict a positive outcome of radiofrequency denervation.
  • Review evidence updates for anesthetic genicular nerve blocks and the evolution in protocol optimization that is underway in current research efforts.

Poster Research Highlights #1 (201)

Increasing both the quality and quantity of scientific pain research is a primary goal of the AAPM Annual Meeting. The Scientific Poster Abstract Committee has selected three of the highest ranking, most novel 2020 poster submissions for live presentation in this session.

ECAP-Controlled Closed-Loop SCS: Double-Blind, Randomized Trial for the Treatment of Chronic Pain – 12-Month Outcomes

Timothy Deer, MD

Sleep Quality Improvements Observed in the Evoke Study of ECAP Measurement and ECAP-Controlled Closed-Loop SCS

Shrif Costandi, MD

Identifying Phenotypic Subpopulations of Chronic Pain Patients Using K-Means Cluster Analysis of Body Map Data

Nathan Anderson, BA MDiv

Learning Objectives:

  • Review 12-month outcomes data for ECAP-controlled, closed-loop SCS.
  • Discuss sleep quality improvements following the Evoke Study of ECAP Measurement.
  • Discuss subpopulations of chronic pain patients.
