In the midst of the COVID-19 pandemic, data has shown that age-adjusted overdose death rates involving synthetic opioids, psychostimulants, cocaine, and heroin have been increasing, including prescription opioid deaths, which were declining, but, recently, reversing the trends. Contrary to widely held perceptions, the problem of misuse, abuse, and diversion of prescription opioids has been the least of all the factors in recent years. Consequently, it is important to properly distinguish between the role of illicit and prescription opioids in the current opioid crisis. Multiple efforts have been based on consensus on administrative policies for certain harm reduction strategies for individuals actively using illicit drugs and reducing opioid prescriptions leading to curbing of medically needed opioids, which have been ineffective. While there is no denial that prescription opioids can be misused, abused, and diverted, the policies have oversimplified the issue by curbing prescription opioids and the pendulum has swung too far in the direction of severely limiting prescription opioids, without acknowledgement that opioids have legitimate uses for persons suffering from chronic pain. Similar to the opioid crisis, interventional pain management procedures have been affected by various policies being applied to reduce overuse, abuse, and finally utilization. Medical policies have been becoming more restrictive with reduction of access to certain procedures, with the pendulum swinging too far in the direction of limiting interventional techniques. Recent utilization assessments have shown a consistent decline for most interventional techniques, with a 18.7% decrease from 2019 to 2020. The causes for these dynamic changes are multifactorial likely including the misapplication of the 2016 Centers for Disease Control and Prevention (CDC) guidelines for prescribing opioids for chronic pain, the relative ease of access to illicit synthetic opioids and more recently issues related to the COVID-19 pandemic. In addition, recent publications have shown association of dose tapering with overdose or mental health crisis among patients prescribed long-term opioids. These findings are leading to the hypothesis that federal guidelines may inadvertently be contributing to an increase in overall opioid deaths and diminished access to interventional techniques. Together, these have resulted in a fourth wave of the opioid epidemic. ⋯ The opioid overdose waves over the past three decades have resulted from different etiologies. Wave one was associated with prescription opioid overdose deaths and wave two with the rise in heroin and overdose deaths from 1999 to 2013. Wave three was associated with a rise in synthetic opioid overdose deaths. Sadly, wave four continues to escalate with increasing number of deaths as a confluence of factors including the CDC guidelines, the COVID pandemic, increased availability of illicit synthetic opioids and the reduction of access to interventional techniques, which leads patients to seek remedies on their own.

Randomized Controlled Trial
Comparison of Caudal Versus Transforaminal Epidural Steroid Injection in Post Lumbar Surgery Syndrome After Single-level Discectomy: A Prospective, Randomized Trial.
Epidural fibrosis (EF) is one of the leading causes of post lumbar surgery syndrome (PLSS). Although there are studies in the literature suggesting that lumbar epidural steroid injections are an effective method in the pain management of PLSS caused by EF, no study is available comparing the effectiveness and safety of caudal and transforaminal approaches. ⋯ Both CESI and TFESI are effective and safe methods in the treatment of PLSS caused by EF following lumbar discectomy. These methods can reduce pain and disability. Although both methods have similar treatment success rates, TFESI seems to be a more effective treatment method in reducing disability at 3-week follow-up.

Piriformis syndrome is a constellation of symptoms associated with low back, gluteal, and sciatic pain. One treatment for piriformis syndrome is the injection of local anesthetic, steroid, or botulinum toxin into the piriformis muscle. Various approaches for needle navigation into the piriformis muscle have been described using fluoroscopy or ultrasound. This study introduces a new method of image guidance combining fluoroscopy and ultrasound. ⋯ Piriformis injections using combined fluoroscopic and ultrasound guidance provides comparable efficiency to standard techniques and may result in improved accuracy into the target and thus improved efficacy. Larger prospective trials are required to comprehensively examine the efficacy of this novel technique.

Observational Study
The Ultrasound-guided Anteromedial Joint Line Approach: A Targeted Corticosteroid Injection Technique for Patients With Medial Knee Pain.
Medial knee pain is a common complaint in the adult population. When conservative measures fail, intraarticular knee corticosteroid injections are often offered through the superolateral approach into the suprapatellar recess to provide short-term relief. However, some patients fail to respond and require alternative approaches. The anteromedial joint line (AMJL) approach, which targets the medial compartment, may be more effective when pain-generating pathologies such as synovitis are located in the medial compartment. To date, there have been no dedicated studies evaluating ultrasound-guided (USg) corticosteroid injections through the AMJL approach to reduce medial knee pain. ⋯ USg AMJL injection is a safe and effective procedure for targeting medial knee pain, particularly in the settings of obesity and prior failed superolateral and suprapatellar knee injections. Further investigation is required to assess long-term clinical outcomes of this injection approach.
