Introduction: Chronic refractory low back and lower extremity pain recalcitrant to conservative management and epidural injections secondary to postsurgery syndrome, spinal stenosis, and disc herniation are sometimes managed with percutaneous adhesiolysis. Consequently, this systematic review and meta-analysis was undertaken to assess the efficacy of percutaneous adhesiolysis in managing low back and lower extremity pain., Methods: A systematic review and meta-analysis of randomized controlled trials (RCTs) utilizing the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist was performed. A comprehensive literature search of multiple databases from 1966 to July 2022, including manual searches of the bibliography of known review articles was performed. Quality assessment of the included trials, meta-analysis, and best evidence synthesis was performed. The primary outcome measure was a significant reduction in pain (short term up to 6 months and long term more than 6 months)., Results: The search identified 26 publications, with 9 trials meeting the inclusion criteria. The results of dual-arm and single-arm analyses showed significant improvement in pain and function at 12 months. Opioid consumption was also significantly reduced at 6 months with dual-arm analysis, whereas single-arm analysis showed a significant decrease from baseline to treatment at the 3-, 6-, and 12-month analyses. At 1 year follow-up, seven of seven trials were positive for improvements in pain relief, function, and diminution of opioid use., Discussion: Based on the present systematic review of nine RCTs, the evidence level is I to II, with moderate to strong recommendation for percutaneous adhesiolysis in managing low back and lower extremity pain. The limitations of the evidence include paucity of literature, lack of placebo-controlled trials, and the majority of the trials studying post lumbar surgery syndrome., Conclusion: The evidence is level I to II or strong to moderate based on five high-quality and two moderate-quality RCTs, with 1 year follow-up that percutaneous adhesiolysis is efficacious in the treatment of chronic refractory low back and lower extremity pain., (© 2023.

Introduction: The COVID-19 pandemic resulted in major disruptions in all aspects of human life including a decline of medical services utilized during 2020. An analysis of the impact of COVID-19 pandemic showed an 18.7% reduction in utilization patterns of interventional techniques in managing chronic pain in the Medicare population from 2019 to 2020. However, specific changes in utilization patterns of facet joint interventions have not been studied. Thus, we sought to assess the utilization patterns including an update of facet joint interventions from 2018 to 2020, with analysis of the impact of COVID-19 pandemic in managing chronic spinal pain utilizing facet joint interventions in the fee-for-service Medicare population of the United States., Methods: The present investigation was designed to assess utilization patterns and variables of facet joint interventions, in managing chronic spinal pain from 2010 to 2020 in the fee-for-service (FFS) Medicare population in the United States (US), and how the COVID-19 pandemic impacted these utilization patterns. Data for the analysis were obtained from the master database from the Centers for Medicare & Medicaid Services (CMS) physician/supplier procedure summary from 2000 to 2020., Results: Results of this analysis showed significant impact of COVID-19 with overall decrease of 18.5% of all facet joint interventions per 100,000 Medicare population compared to 20.2 and 20.5% decrease for lumbar and cervical facet joint injections, 15 and 13.1% decrease per 100,000 Medicare population of lumbosacral and cervicothoracic facet joint neurolysis procedures. The results are significant in that comparative analysis from 2000 to 2010 and 2010 to 2019 showing an annual increase of 14.4 vs. 2.2%, illustrating a decelerating pattern. There were also significant growth patterns noted with decreases in facet joint injections and nerve blocks compared to facet joint neurolytic procedures., Conclusions: This analysis shows a significant effect of COVID-19 producing an overall decrease in utilization of facet joint interventions relative to pre-COVID data. Further, the analysis demonstrates continued deceleration of utilization patterns of facet joint interventions compared to the periods of 2000-2010 and 2010-2019., (© 2023. The Author(s).)

The COVID-19 pandemic has affected the entire world and catapulted the United States into one of the deepest recessions in history. While this pandemic rages, the opioid crisis worsens. During this period, the pandemic has resulted in the decimation of most conventional medical services, including those of chronic pain management, with the exception of virtual care and telehealth. Many chronic pain patients have been impacted in numerous ways, with increases in cardiovascular disease, mental health problems, cognitive dysfunction, and early death. The epidemic has also resulted in severe economic and physiological consequences for providers. Drug deaths in America, which fell for the first time in 25 years in 2018, rose to record numbers in 2019 and are continuing to climb, worsened by the coronavirus pandemic. The opioid epidemic was already resurfacing with a 5% increase in overall deaths from 2018; however, the preliminary data show that prescription opioid deaths continued to decline, while at the same time deaths due to fentanyl, methamphetamine, and cocaine climbed, with some reductions in heroin deaths. The health tracker data also showed that along with an almost 88% decline in elective surgeries, pain-related prescriptions declined 15.1%. Despite increases in telehealth, outpatient services declined and only began returning towards normal at an extremely slow pace, accompanied by reduced productivity and increased practice costs. This review, therefore, emphasizes the devastating consequences of concurrent epidemics on chronic pain management and the need to develop best practice efforts to preserve access to treatment for chronic pain.

The treatment of noncancer pain in the United States and globally is met with significant challenges, resulting in profound physical, emotional, and societal costs. Based on this need, numerous modalities have been proposed to manage chronic pain, including opioid and nonopioid interventions as well as surgical approaches. Thus, the future of pain management continues to be mired in evolving concepts and constant debates. Consequently, it is crucial to understand the past as we move towards the future. The evolution of lessons for better pain management at present and for the future starting from the 1990s to the present date are reviewed and emphasized with a focus on learning from the past for the future. This review summarizes the evolution of multiple modalities of treatments, including multidisciplinary programs, multimodal therapy, interventional techniques, opioid therapy, other conservative modalities, and surgical interventions. This review emphasizes the individual, patient-centered development of an effective pain treatment plan after proper evaluation to establish a diagnosis. It includes measurable outcomes that focus on improvements in the quality of life and activities of daily living, as well as improvement in pain and function and, most importantly, return to productive citizenship. It is crucial that the knowledge of best practices be advanced, along with emphasis on lessons learned in the past to provide best practices for better pain management.

Introduction: This compilation presents a comprehensive review of the literature on common chronic pain conditions of the hand. It briefly presents these common conditions with their biological background, diagnosis, and common management options. It then presents and compares the latest literature available for injection techniques to treat these diagnoses and compares the available evidence., Methods: A comprehensive literature review was performed in MEDLINE, PubMed, and Cochrane databases from 1996 to 2019 using the terms "hand pain", "injection techniques", "steroid injection", "chronic pain", "osteoarthritis", "rheumatoid arthritis", "carpal tunnel syndrome", "De Quervain's tenosynovitis", "ganglion cyst", "gout", "Raynaud's", and "stenosing tenosynovitis"., Results: Hand pain is a common condition with 9.7% prevalence in men and 21.6% in women and can cause significant morbidity and disability. It also carries a significant cost to the individuals and the healthcare system, totaling in $4 billion dollars in 2003. Injection therapy is an alternative when conservative treatment fails. Osteoarthritis is the most common chronic hand pain syndrome and affects about 16% of the population. Its mechanism is largely mechanic, and as such, there is controversy if steroid injections are of benefit. Hyaluronic acid (HA) appears to provide substantial relief of pain and may increase functionality. More studies of HA are required to make a definite judgment on its efficacy. Similarly, steroid ganglion cyst injection may confer little benefit. Carpal tunnel syndrome is a compressive neuropathy, and only temporarily relieved with injection therapy. US-guidance provides significant improvement and, while severe cases may still require surgery, can provide a valuable bridge therapy to surgery when conservative treatment fails. Similar bridging treatments and increased efficacy under US-guidance are effective for stenosing tenosynovitis ("trigger finger"), though, interestingly, inflammatory background is associated with decreased effect in this case. When the etiology of the pain is inflammatory, such as in RA, corticosteroid (CS) injections provide significant pain relief and increased functionality. They do not, however, change the course of disease (unlike DMARDs). Another such example is De-Quervain tenosynovitis that sees good benefit from CS injections, and an increased efficacy with US-guidance, and similarly are CS injections for gout. For Raynaud's phenomenon, Botox injections have encouraging results, but more studies are needed to determine safety and efficacy, as well as the possible difference in effect between primary and secondary Raynaud's., Conclusions: Chronic hand pain is a prevalent and serious condition and can cause significant morbidity and disability and interferes with independence and activities of daily living. Conservative treatment remains the first line of treatment; however, when first-line treatments fail, steroid injections can usually provide benefit. In some cases, HA or Botox may also be beneficial. US-guidance is increasing in hand injection and almost ubiquitously provides safer, more effective injections. Hand surgery remains the alternative for refractory pain.

Purpose of Review: This is a comprehensive literature review of the available evidence and techniques of foot injections for chronic pain conditions. It briefly describes common foot chronic pain syndromes and then reviews available injection techniques for each of these syndromes, weighing the available evidence and comparing the available approaches., Recent Findings: Foot and ankle pain affects 20% of the population over 50 and significantly impairs mobility and ability to participate in activities of daily living (ADLs), as well as increases fall risk. It is commonly treated with costly surgery, at times with questionable efficacy. Injection therapy is challenging when the etiology is anatomical or compressive. Morton's neuroma is a budging of the interdigital nerve. Steroid, alcohol, and capsaicin injections provide some benefit, but it is short lived. Hyaluronic acid (HA) injection provided long-term relief and could prove to be a viable treatment option. Achilles tendinopathy (AT) is most likely secondary to repeat tendon stress-platelet-rich-plasma (PRP) and prolotherapy have been trialed for this condition, but more evidence is required to show efficacy. Similar injections were trials for plantar fasciitis and achieved only short-term relief; however, some evidence suggests that PRP injections reduce the frequency of required therapy. Tarsal tunnel syndrome, a compressive neuropathy carries a risk of permanent neural injury if left untreated. Injection therapy can provide a bridge to surgery; however, surgical decompression remains the definitive therapy. When the etiology is inflammatory, steroid injection is more likely to provide benefit. This has been shown in several studies for gout, as well as osteoarthritis of the foot and ankle and treatment-refractory rheumatoid arthritis. HA showed similar benefit, possibly due to anti-inflammatory effects. Stem cell injections may provide the additional benefit of structure restoration. Chronic foot pain is common in the general population and has significant associated morbidity and disability. Traditionally treated with surgery, these are costly and only somewhat effective. Injections provide an effective alternative financially and some evidence exists that they are effective in pain alleviation. However, current evidence is limited and the benefit described from injection therapy has been short-lived in most cases. Further studies in larger populations are required to evaluate the long-term effects of these treatments.
