    Ultrasound-guided spinal accessory nerve block for intractable trapezius pain: A case series. Herbst Meghan Kelly,Sorkin Ryan The American journal of emergency medicine Myofascial pain affects about 10% of the United States population, often involves the trapezius muscle, and can be difficult to manage using conventional analgesic medications in the Emergency Department (ED). The use of ultrasound-guided nerve blocks performed by emergency physicians is well-documented, but this is the first report describing the technique and effectiveness of an ultrasound-guided spinal accessory nerve block for acutely treating trapezius myofascial pain in the ED setting. In this case series of three patients with intractable trapezius pain, the ultrasound-guided spinal accessory nerve block proved feasible and offered substantial therapeutic benefit. 10.1016/j.ajem.2021.08.026
    New ultrasound-guided techniques in chronic pain management: an update. Ergönenç Tolga,Stockman Janneken Current opinion in anaesthesiology PURPOSE OF REVIEW:The introduction of ultrasound guidance in interventional pain management leads to the development of new interventional pain management techniques. Ultrasound-guided (UG) interventional pain management is rapidly developing and increasingly more commonly used, due to its many advantages over traditional radiologic imaging modalities. This review will summarize recent literature around novel interventional pain techniques with ultrasound guidance published over the last 18 months. RECENT FINDINGS:Many new interventional pain management methods have been described in the last few years in the literature. The use of ultrasonography in interventional pain management played a crucial role in these developments. This review includes newly described interventional methods in the literature. The review particularly focussed on the methods that are used to treat the pain in the hip, shoulder, knee, and lumbar area. These new techniques hold promise for significant improvements in the efficacy and safety of interventional pain management. SUMMARY:There have been many innovations in UG interventional procedures, however, some of them require more rigorous validation before their widespread use. 10.1097/ACO.0000000000001037
    Medical ozone therapy in facet joint syndrome: an overview of sonoanatomy, ultrasound-guided injection techniques and potential mechanism of action. Latini Eleonora,Curci Enrico Roberto,Nusca Sveva Maria,Lacopo Alessandra,Musa Francesca,Santoboni Flavia,Trischitta Donatella,Vetrano Mario,Vulpiani Maria Chiara Medical gas research Facet joint osteoarthritis is the most prevalent source of facet joint pain and represents a significant cause of low back pain. Oxygen-ozone therapy has been shown to have positive results in acute and chronic spinal degeneration diseases and it could be a safe and efficacious alternative to traditional facet joint conservative treatments. This review article explains the interventional facet joint management with ultrasound-guided oxygen-ozone therapy, providing an anatomy/sonoanatomy overview of lumbar facet joints and summarizing the potential mechanism of action of oxygen-ozone in the treatment of facet joint osteoarthritis, not yet fully understood. 10.4103/2045-9912.318859
