Physicians should resist external pressure for a quick return of athletes to playing sports by the use of joint or soft tissue injections. Arch. Dexamethasone is usually given by injection only if you are unable to take the medicine by mouth. Would you like email updates of new search results? Accessibility Avoid drinking alcohol while you are taking dexamethasone. Trigger points are first located by manual palpation with a variety of techniques (Figure 24-3). TPIs may be classified according to the substances injected, which may include local anesthetic, saline, sterile water, steroids, nonsteroidal anti-inflammatory drugs, botulinum toxin, 5-HT3 receptor antagonists, or even dry needling. A common practice is to use 0.5 to 2mL per trigger point, which may depend on the pharmacologic dosing limits of the injected mixture.11,12,14,15,1921,26,32,33,50 For example, the total dose of Botox A administered during TPIs ranged from 5 to 100 units/site, for 10-20 sites, up to a total of 250 units.18,22,24,25 Lidocaine is a frequently used local anesthetic for TPIs; a dilution to 0.2% to 0.25% with sterile water has been suggested as the least painful on injection.11,13-15,18,26 Other studies have used ropivacaine or bupivacaine 0.5% with or without dexamethasone.12, The injection technique recommended by Hong and Hsueh for trigger points was modified from that proposed by Travell and Simons.13,50 It described holding the syringe in the dominant hand while palpating the trigger point with the thumb or index finger of the opposite hand (Figure 24-4). However, its use is safer for both patient and physician than the original volatile vapor coolant, ethyl chloride. Also, early reaccumulation of fluid can occur in many cases. When injecting or aspirating a joint space, sterile technique should be used. Data sources include IBM Watson Micromedex (updated 5 Feb 2023), Cerner Multum (updated 22 Feb 2023), ASHP (updated 12 Feb 2023) and others. Intratendinous injection should be avoided because of the likelihood of weakening the tendon. Few studies have investigated the efficacy or duration of action of the various agents in joints or soft tissue sites. J Hand Surg Am. They produce pain locally and in a referred pattern and often accompany chronic musculoskeletal disorders. Pressure threshold is the minimum pressure that reproduces pain (or tenderness) in a suspected trigger point, and has been claimed to be an objective, reproducible, and reliable method for their detection. For instance, suspected septic arthritis is a contraindication for therapeutic injection, but an indication for joint aspiration. Avoid being near people who are sick or have infections. Needle breakage; avoid by never inserting the needle to its hub. For all intra-articular injections, sterile technique should be used. Her contribution to medical pain management was primarily the study and description of myofascial pain with the publication, along with coauthor and physician David Simons, of the text Myofascial Pain and Dysfunction: The Trigger Point Manual in 1983.44 Travell and Simons continued to advance their proposed understanding of myofascial pain treatment and published a second edition of their manual in 1992.2 Although the method proposed by Travell and Simons for identifying and injecting trigger points became prominent, it was based largely on anecdotal observations and their personal clinical experience.39,45 The use of injection therapy for trigger points had previously been reported almost four decades earlier in 1955 by Sola and Kuitert, who noted that Procaine and pontocaine have been most commonly used but Martin has reported success with injections of benzyl salicylate, camphor, and arachis oil.46. This content is owned by the AAFP. Dexamethasone sodium phosphate injection USP is a sterile, clear, colorless solution, free from visible particles and a water-soluble inorganic ester of dexamethasone which produces a rapid response even when injected intramuscularly. bruising under the skin. On rare occasions, patients exhibit signs of anesthetic toxicity, including flushing, hives, chest or abdominal discomfort, and nausea. Trigger point injections cause less soreness than dry-needling techniques. Pain can be relieved by alternately applying moist heat and ice for a day or two. 3. This study prompted some clinicians to abandon the local twitch response to more reliably quantify tenderness with pressure thresholds, as reflected in the most current diagnostic criteria for trigger points.24, Pressure threshold is the minimum pressure that reproduces pain (or tenderness) in a suspected trigger point, and has been claimed to be an objective, reproducible, and reliable method for their detection.48,50,7577 Fischer attempted to establish standard, normal pressure thresholds, which were found to be different for each gender and each muscle.76, Click to share on Twitter (Opens in new window), Click to share on Facebook (Opens in new window), Click to share on Google+ (Opens in new window). Description Your health care provider inserts a small needle and injects medicine into the painful and inflamed area. It is used in the management of certain types of edema (fluid retention and swelling; excess fluid held in body tissues,) gastrointestinal disease, and certain types of arthritis. A trigger point is defined as a specific point or area where, if stimulated by touch or pressure, a painful response will be induced. The needle is then withdrawn to the level of the subcutaneous tissue, then redirected superiorly, inferiorly, laterally and medially, repeating the needling and injection process in each direction until the local twitch response is no longer elicited or resisting muscle tautness is no longer perceived (Figure 3c).10. sharing sensitive information, make sure youre on a federal 2021 Jul;16(4):542-545. doi: 10.1177/1558944719867135. Table 1 lists soft tissue and joint condition indications for diagnostic and therapeutic injections. 17 In fact, in a . Many researchers agree that acute trauma or repetitive microtrauma may lead to the development of a trigger point. Hyperglycemia is possible in patients who have diabetes. Therapeutic injection with corticosteroids should always be viewed as adjuvant therapy.6 The improper or indiscriminate use of corticosteroids is likely to have a bad outcome. However, these injections are probably best performed by physicians with postgraduate education in musculoskeletal anatomy, and a greater understanding of orthopedic and neurologic disorders. Cardone DA et al. Click on the image (or right click) to open the source website in a new browser window. doi: 10.7759/cureus.16856. The injection technique recommended by Hong and Hsueh for trigger points was modified from that proposed by Travell and Simons. A common practice is to use 0.5 to 2mL per trigger point, which may depend on the pharmacologic dosing limits of the injected mixture. Identification of trigger points is required before performing these injections and is generally performed with a thorough manual and orthopedic examination. Relative contraindications are less well defined and should be considered on a case-by-case basis. Am Fam Physicians 2002; 66(2):283-289 4. For most injections, 1 percent lidocaine or 0.25 to 0.5 percent bupivacaine is mixed with a corticosteroid preparation. On rare occasions, patients exhibit signs of anesthetic toxicity, including. As a rule, larger joints require more corticosteroid. increased growth of face or body hair. There is some concern that corticosteroid preparations, with repeated use, may accelerate normal, aging-related articular cartilage atrophy or may weaken tendons or ligaments. A thoracic epidural injection may provide pain relief for several different types of back problems, like: Injuries causing irritation of the spinal nerves. In comparative studies,17 dry needling was found to be as effective as injecting an anesthetic solution such as procaine (Novocain) or lidocaine (Xylocaine).10 However, post-injection soreness resulting from dry needling was found to be more intense and of longer duration than the soreness experienced by patients injected with lidocaine.10, One noncontrolled study17 comparing the use of dry needling versus injection of lidocaine to treat trigger points showed that 58 percent of patients reported complete relief of pain immediately after trigger-point injection and the remaining 42 percent of patients claimed that their pain was minimal (12/10) on the pain scale. eCollection 2021 Aug. N JHS, L AHAF, R GVG, da Silveira DCEC, B PN, Almeida SF. Side effects may include slight soreness at the injection site, but most people feel pain relief in the muscle right away. PT. Comparison of Different Dosages and Volumes of Triamcinolone in the Treatment of Stenosing Tenosynovitis: A Prospective, Blinded, Randomized Trial. The German anatomist Froriep referred to tender spots occurring in muscles as muscle calluses in 1843; these points were called myalgic spots by Gutstein in 1938. The agents differ according to potency (Table 3), solubility, and crystalline structure. Kegel G et al. Compression of the point for 2 minutes allowed hemostasis, which was followed by stretching of the muscle. TPI also can be used to treat fibromyalgia and tension headaches. Key points Trigger finger is a common cause of hand pain and dysfunction with a bimodal distribution in . Ask your doctor before stopping the medicine. These trigger points produce a referred pain pattern characteristic for that . Ann This includes prescription and over-the-counter medicines, vitamins, and herbal products. The Spray and Stretch technique involves passively stretching the target muscle while simultaneously applying dichlorodifluoromethane-trichloromonofluoromethane (Fluori-Methane) or ethyl chloride spray topically.5 The sudden drop in skin temperature is thought to produce temporary anesthesia by blocking the spinal stretch reflex and the sensation of pain at a higher center.5,10 The decreased pain sensation allows the muscle to be passively stretched toward normal length, which then helps to inactivate trigger points, relieve muscle spasm, and reduce referred pain.5, Dichlorodifluoromethane-trichloromono-fluoromethane is a nontoxic, nonflammable vapor coolant spray that does not irritate the skin but is no longer commercially available for other purposes because of its effect in reducing the ozone layer. Synovial fluid evaluation can differentiate among various joint disease etiologies including infection, inflammation, and trauma. For therapeutic injections, the procedure should be performed when acute or chronic symptoms are present, after the diagnosis and therapeutic plan have been made, and after consideration has been given to obtaining radiographs. Each subject received a single injection of 6 mg of dexamethasone acetate. Often, the muscles used to maintain body posture are affected, namely the muscles in the neck, shoulders, and pelvic girdle, including the upper trapezius, scalene, sternocleidomastoid, levator scapulae, and quadratus lumborum.13 Although the pain is usually related to muscle activity, it may be constant. A numbing medication like Ethyl Chloride is used to reduce the pain . Although a few states currently allow physical therapists or naturopaths to perform dry needling, most states do not permit such injections by nonphysicians.47 This intervention is typically performed in private outpatient clinics, but can also be offered in specialty pain management or spine clinics. This acetylcholine was thought to depolarize the postjunctional membrane, resulting in prolonged Ca++ release, continuous muscle fiber shortening, and increased metabolism. A trigger point injection can help soothe myofascial pain, especially in your neck, shoulder, arms, legs and lower back. The US Food and Drug Administration regulates the medications commonly administered during TPIs and most are approved for these indications. Tell any doctor who treats you that you are using dexamethasone. Brand names: Decadron, De-Sone LA When accompanied by other symptoms, trigger points may also constitute myofascial pain syndrome, one of the most frequent causes of musculoskeletal pain (Figure 24-2).8 Many often inaccurate terms have been used to denote trigger points, including Travell points, myofascial pain syndrome, myofascitis, fibrositis, myofibrositis, myalgia, muscular rheumatism, idiopathic myalgia, regional fibromyalgia, nonarthritic rheumatism, tendinomyopathy nonarticular rheumatism, local fibromyalgia, and regional soft-tissue pain.1,9. Tell your doctor about any such situation that affects you. Womack ME, Ryan JC, Shillingford-Cole V, Speicher S, Hogue GD. Unauthorized use of these marks is strictly prohibited. A central trigger point (TrP) located within a taut band of muscle. weight gain. Decadron (dexamethasone) is a corticosteroid, similar to a natural hormone produced by the adrenal glands, used to treat arthritis, skin, blood, kidney, eye, thyroid, intestinal disorders, severe allergies, and asthma. However, insufficient training in trigger point examination likely impedes recognition of myofascial pain, and palpation generally has poor interrater reliability.

Steroid injections may be given every 3-4 months but frequent injections may lead to tissue weakening at the injection site and . Additional proinflammatory mediators (e.g., adenosine triphosphate, serotonin, tumor necrosis factor-1a, interleukin 1, substance P, and H ions) are then released from damaged muscle fibers, leading to activation of nociceptors and end-plate activity. Corticosteroid injections effective for trigger finger in adults in general practice: a double-blinded randomised placebo controlled trial. If therapeutic effect is achieved, a maximum of four injections per year is recommended. A person viewing it online may make one printout of the material and may use that printout only for his or her personal, non-commercial reference. Copyright 2002 by the American Academy of Family Physicians. Avoid receiving a "live" vaccine, or you could develop a serious infection. Dexamethasone comes as an oral tablet, oral solution, eye drops, and ear drops. The main hypothesis of this study is that anti-inflammatory medications (ketorolac or dexamethasone) will provide longer-lasting and greater pain relief than just lidocaine in trigger point injections where a local twitch response is evoked at the time of the injection. Using a needle with a smaller diameter may cause less discomfort; however, it may provide neither the required mechanical disruption of the trigger point nor adequate sensitivity to the physician when penetrating the overlying skin and subcutaneous tissue. Potency is generally measured against hydrocortisone, and ranges from low-potency, short-acting agents such as cortisone, to high-potency, long-acting agents such as betamethasone (Celestone). We can do trigger point injections, usually using a cocktail of lidocain and dexamethasone, we have used Serapin and like it for occipital trigger areas, but prefer the dexamethasone for trapezius and rhomboid areas. No laboratory test or imaging technique has been established for diagnosing trigger points.9 However, the use of ultrasonography, electromyography, thermography, and muscle biopsy has been studied. Commonly used. Furthermore, manual methods are indicated for patients who have an extreme fear of needles or when the trigger point is in the middle of a muscle belly not easily accessible by injection (i.e., psoas and iliacus muscles).10 The goal of manual therapy is to train the patient to effectively self-manage the pain and dysfunction. The highest inter- and intra-examiner reliability for locating trigger points was achieved with pressure threshold algometry. The concept of abnormal end-plate potentials was used to justify injection of botulinum toxin to block acetylcholine release in trigger points.57 McPartland has expanded on the idea of excessive acetylcholine by suggesting that congenital or acquired genetic defects in presynaptic, synaptic, or postsynaptic structures may contribute to an individuals susceptibility to myofascial pain.45. For example, a lidocaine (Xylocaine) injection into the subacromial space can help in the diagnosis of shoulder impingement syndromes, and the injection of corticosteroids into the subacromial space can be a useful therapeutic technique for subacromial impingement syndromes and rotator cuff tendinopathies. If additional tender points are palpable, they should be isolated, needled and injected. It is available in forms that can be taken by mouth, through a patch placed on the skin, as a cream, in eye drops, and as an injectable.
