Cervical facet joint pain is often managed with either cervical radiofrequency neurotomy, cervical medial branch blocks, or cervical intraarticular injections. However, the effectiveness of each modality continues to be debated. Further, there is no agreement in reference to superiority or inferiority of facet joint nerve blocks compared to radiofrequency neurotomy, even though cervical facet joint radiofrequency neurotomy has been preferred by many and in fact, has been mandated by the Centers for Medicare and Medicaid Services (CMS), except when radiofrequency cannot be confirmed. Each procedure has advantages and disadvantages in reference to clinical utility, outcomes, cost utility, and side effect profile. However, comparative analysis has not been performed thus far in the literature in a clinical setting. ⋯ In this study, outcomes of cervical therapeutic medial branch blocks compared to radiofrequency neurotomy demonstrated significantly better outcomes with significant pain relief with similar costs for both treatments over a period of one year.

Randomized Controlled Trial Multicenter Study
Safety and Efficacy of Platelet Rich Plasma for Treatment of Lumbar Discogenic Pain: A Prospective, Multicenter, Randomized, Double-blind Study.
Interventions for chronic discogenic spine pain are currently insufficient in lowering individual patient suffering and global disease burden. A 2016 study of platelet rich plasma (PRP) for chronic discogenic pain previously demonstrated clinically significant response among active group patients compared with controls. ⋯ These findings are markedly different than the highly promising results of the 2016 PRP study. This study posits necessary caution for researchers who wish to administer PRP for therapeutic benefit and may ultimately point to necessary redirection of interventional research for discogenic pain populations.

During the last decades, platelet-rich plasma has been studied for the treatment of multiple chronic pain conditions, in addition to being employed in the enhancement of healing after tissue injury. ⋯ Future research addressing the utilization of platelet-rich plasma in the treatment of chronic pain conditions should focus on shedding light on the following major questions: a) Is there a dose-effect relation between the platelet count and the clinical efficacy of the preparation?; b) What pathology determinants should be considered when selecting between leukocyte-enriched and leukocyte-depleted concentrates?; c) What is the role of platelet activation methods on the clinical efficacy of platelet-rich plasma?; d) Is there an optimal number of injections and time frame for application of multiple injection treatment cycles?; e) Does the addition of local anesthetics affect the clinical efficacy of platelet-rich plasma?; and f) Is there potential for future platelet-rich plasma applications for the treatment of neuropathic pain of peripheral origin?
