Methylprednisolone (Depo-Medrol) is often the agent selected for soft tissue injection. Description Your health care provider inserts a small needle and injects medicine into the painful and inflamed area. A trigger point injection (TPI) is an outpatient procedure used to treat painful areas of muscle that contain trigger points, or "knots" of muscle that form when muscles do not relax. To avoid direct needle injury to articular cartilage or local nerves, attention should be paid to anatomic landmarks and depth of injection. Diagnostic imaging or other forms of advanced testing is generally not required before administering this intervention for CLBP. 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. Tell your doctor about all your medical conditions, and all the medicines you are using. What is a trigger point? Thoracic post-surgical spine syndrome. Myofascial trigger points are self-sustaining hyperirritative foci that may occur in any skeletal muscle in response to strain produced by acute or chronic overload. However, insufficient training in trigger point examination likely impedes recognition of myofascial pain, and palpation generally has poor interrater reliability.2,44,71 Hsieh and colleagues reported difficulties when attempting to reproduce findings of taut bands and local twitch responses, both characteristics of trigger points, in the lower back.72 In a study of intra-rater reliability, local twitch response and referred pain varied from one session to the next while taut bands, tender points, and jump sign remained consistent.73 Likewise, Njoo and van der Does found that jump sign and reproduction of pain were much more reliable than referred pain in identifying myofascial pain.74 It is interesting to note that when Hong and colleagues compared referred pain response from needling and palpation, they found that only 53.9% of their patients had referred pain from palpation, compared with 87.6% when needling.35, Differentiating between the trigger points of myofascial pain syndrome and the tender points of fibromyalgia syndrome has also proven problematic. The serious complication of pneumothorax can be avoided by refraining from aiming the needle at an intercostal space. J Am Acad Orthop Surg. A muscle fiber energy crisis was hypothesized to produce taut bands. Ball EM et al. To minimize pain and inflammation after leaving the office, the patient should be advised to apply ice to the injection site (for no longer than 15 minutes at a time, once or twice per hour), and non-steroidal anti-inflammatory agents may be used, especially for the first 24 to 48 hours. The indications for joint or soft tissue aspiration and injection fall into two categories: diagnostic and therapeutic. 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. Trigger point injections are a therapeutic modality to treat myofascial trigger points, especially in symptomatic patients, and have been demonstrated effectiveness to inactivate trigger points. Mixing the corticosteroid preparation with a local anesthetic is a common practice for avoiding the injection of a highly concentrated suspension into a single area. 2008 Sep;67(9):1262-6. doi: 10.1136/ard.2007.073106. Dexamethasone is a steroid medicine used to treat many different conditions such as allergic disorders, skin conditions, ulcerative colitis, arthritis, lupus, psoriasis, breathing disorders, eye conditions, blood cell disorders, leukemia, multiple sclerosis, inflammation of the joints or tendons, and problems caused by low adrenal gland hormone levels. St. Louis, Mosby, 2009. Patient positioning should be comfortable to minimize involuntary muscle contractions and facilitate access to the painful areas. Injections of an anesthetic mixture directly into the muscle can help the muscle relax and relieve pain. Hand (N Y). Side Effects Problems with cortisone shots can range from mild to quite serious. The physiology of trigger points themselves is controversial, and therefore the mechanism of action through which injections aimed at trigger points may relieve pain is unknown.39 In 1979, a theory of diffuse noxious inhibitory control was suggested where noxious input from nociceptive afferent fibers inhibited dorsal horn efferents as a counter irritant from a distant location.53 Some support was given to this theory when subcutaneous sterile water improved myofascial pain scores after a brief period of severe burning pain at that site.54 Spontaneous electrical activity was found more frequently in rabbit and human trigger points.9,55 Simons56 theorized that the spontaneous electrical activity found in active trigger point loci was abnormal end-plate potentials from excessive acetylcholine leakage. About 23 million persons, or 10 percent of the U.S. population, have one or more chronic disorders of the musculoskeletal system.1 Musculoskeletal disorders are the main cause of disability in the working-age population and are among the leading causes of disability in other age groups.2 Myofascial pain syndrome is a common painful muscle disorder caused by myofascial trigger points.3 This must be differentiated from fibromyalgia syndrome, which involves multiple tender spots or tender points.3 These pain syndromes are often concomitant and may interact with one another. 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. You may have withdrawal symptoms if you stop using dexamethasone suddenly after long-term use. PMC Decadron is also used to treat certain types of cancer and occasionally, cerebral edema. These trigger points can often be felt underneath the skin and cause pain when pressed upon. The sequence of injections was randomized by Latin square design. Evidence-Based Management of Low Back Pain. This material is provided for educational purposes only and is not intended for medical advice, diagnosis or treatment. Concomitantly, patients may also have trigger points with myofascial pain syndrome. Please enable it to take advantage of the complete set of features! Kegel G et al. The needle must be long enough to reach the contraction knots in the trigger point to disrupt them. Version: 5.01. Forty-seven patients with tenderness and/or presence of a TrP over the piriformis muscle received TrP injections under ultrasound guidance. A common diagnostic indication for placing a needle in a joint is the aspiration of synovial fluid for evaluation. Outcome measures included the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire, trigger finger grading according to Quinnell, and satisfaction on a visual analog scale. They produce pain locally and in a referred pattern and often accompany chronic musculoskeletal disorders. ; Fibromyalgia - Fibromyalgia patients with tender and painful area more than 6 are not suitable for injections. a parasite infection that causes diarrhea (such as threadworms); a muscle disorder such as myasthenia gravis; diabetes (steroid medicine may increase glucose levels in your blood or urine); stomach ulcers, ulcerative colitis, diverticulitis, inflammatory bowel disease; congestive heart failure, a heart attack; or. Treating pain with a multimodal approach is paramount in providing safe and effective results for patients. Dosing is site dependent. A central trigger point (TrP) located within a taut band of muscle. Fine and colleagues reported that the analgesic effects of TPIs could be reversed with intravenous naloxone. Clinicians should also inquire about medication history to note prior hypersensitivity/allergy or adverse events (AEs) with drugs similar to those being considered, and evaluate contraindications for these types of drugs. Seigerman D, McEntee RM, Matzon J, Lutsky K, Fletcher D, Rivlin M, Vialonga M, Beredjiklian P. Cureus. (From Muscolino JE: The muscle and bone palpation manual with trigger points, referral patterns, and stretching. Key points Trigger finger is a common cause of hand pain and dysfunction with a bimodal distribution in . Allow adequate time between injections, generally a minimum of four to six weeks. FOIA Compression of the point for 2 minutes allowed hemostasis, which was followed by stretching of the muscle. The triamcinolone cohort had significantly better satisfaction and Quinnell grades than did the dexamethasone cohort at the 6-week follow-up but not at the 3-month follow-up. Physicians should be aware that the contraindications listed are for therapeutic injection and do not apply for diagnostic aspiration of joints or soft tissue areas. We report on 68 women who underwent injections by a single physician and show an improvement in VAS pain scores in 65% of patients. Drug class: Glucocorticoids. Store at room temperature away from moisture and heat. 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 1938.39 Many other eponyms have been used to describe the same phenomenon. The injections were made in the volunteers' upper trapezius muscles; there was a 15-minute interval between injections. Patients are encouraged to remain active, putting muscles through their full range of motion in the week following trigger-point injections, but are advised to avoid strenuous activity, especially in the first three to four days after injection.10. Available for Android and iOS devices. Any physician familiar with the localization of trigger points and the use of therapeutic musculoskeletal injections may perform TPIs. In the absence of an underlying chronic inflammatory arthritis, any joint with an effusion should be radiographed to rule out a fracture or other intra-articular pathologic process. The US Food and Drug Administration regulates the medications commonly administered during TPIs and most are approved for these indications. The long-term clinical efficacy of various therapies is not clear, because data that incorporate pre- and post-treatment assessments with control groups are not available. Dosage. Examples of predisposing activities include holding a telephone receiver between the ear and shoulder to free arms; prolonged bending over a table; sitting in chairs with poor back support, improper height of arm rests or none at all; and moving boxes using improper body mechanics.11, Acute sports injuries caused by acute sprain or repetitive stress (e.g., pitcher's or tennis elbow, golf shoulder), surgical scars, and tissues under tension frequently found after spinal surgery and hip replacement may also predispose a patient to the development of trigger points.12, Patients who have trigger points often report regional, persistent pain that usually results in a decreased range of motion of the muscle in question. The dose of anesthetic varies from 0.25 mL for a flexor tendon sheath (trigger finger) to 5 to 8 mL for larger joints. 1362-6. pain, redness, or irritation at site where injected. Many drugs can affect dexamethasone. ; Local Infection - Trigger points should not be performed in the presence of systemic or local infection. Background In this study, we aimed to compare the efficacy of corticosteroid trigger point injection (TPI) versus extracorporeal shock wave therapy (ESWT) on inferior trigger points in the quadratus lumborum (QL) muscle. The needle size used for TPIs is typically quite small, frequently 25 or 27 gauge (G), but needles as large as 21G have been reported.10-12,14,18-20,24,26,32,50 The length of needle used is dependent on the depth of the trigger point through subcutaneous tissue, but is commonly from 0.75 inches to 2.5 inches.10,12,14,18,20,46,5052 Acupuncture needles may be used for dry needling of trigger points, using 0.16 13mm for facial muscles to 0.30 75mm for larger or deeper muscles. These trigger points produce a referred pain pattern characteristic for that . The point of entry can be marked with an impression from a thumb-nail, a needle cap, or an indelible ink pen. Avoid drinking alcohol while you are taking dexamethasone. Thus, a classic trigger point is defined as the presence of discrete focal tenderness located in a palpable taut band of skeletal muscle, which produces both referred regional pain (zone of reference) and a local twitch response. Peters-Veluthamaningal C, Winters JC, Groenier KH, Jong BM. It is not considered medically necessary to repeat injections more frequently than every 7 days. The intensity of pain was rated on a 0 to 10 cm visual analogue scale (VAS) score. When possible, the patient should be placed in the supine position. Joint and soft tissue injections. A trigger point is defined as a specific point or area where, if stimulated by touch or pressure, a painful response will be induced. 3. Epub 2019 Aug 28. Travell recommends that this is best performed by immediately having the patient actively move each injected muscle through its full range of motion three times, reaching its fully shortened and its fully lengthened position during each cycle.10, Postinjection soreness is to be expected in most cases, and the patient's stated relief of the referred pain pattern notes the success of the injection. Effusion of unknown origin or suspected infection (only diagnostic), Minimal relief after two previous corticosteroid injections, 10 to 25 mg for soft tissue and small joints, Methylprednisolone acetate (Depo-Medrol) or triamcinolone acetonide (Aristocort), 2 to 10 mg for soft tissue and small joints, Dexamethasone sodium phosphate (Decadron), 0.5 to 3 mg for soft tissue and small joints, Betamethasone sodium phosphate and acetate (Celestone Soluspan), 1 to 3 mg for soft tissue and small joints, 25- to 30-gauge 0.5- to 1.0-inch needle for local skin anesthesia, 18- to 20-gauge 1.5-inch needle for aspirations, 22- to 25-gauge 1.0- to 1.5-inch needle for injections, Laboratory tubes for culture or other studies (aspiration), Hemostat (if joint is to be aspirated and then injected using the same needle), Adhesive bandage or other adhesive dressing. We comply with the HONcode standard for trustworthy health information. Intratendinous injection should be avoided because of the likelihood of weakening the tendon. The pain is often described as spreading or radiating.7 Referred pain is an important characteristic of a trigger point. Side Effects. Trigger point injection to the levator ani muscles is a minimally invasive, nonsurgical treatment option for patients who have pelvic floor myofascial spasm and are refractive to physical therapy and medication. This study was designed to test the null hypothesis that there is no difference in resolution of triggering 3 months after injection with either a soluble (dexamethasone) or insoluble (triamcinolone) corticosteroid for idiopathic trigger finger. Patients should sign documentation that informed consent for the procedure was given and understood. Other rare, but possible, complications include pneumothorax (when injecting thoracic trigger points), perilymphatic depigmentation, steroid arthropathy, adrenal suppression, and abnormal uterine bleeding. Figure 24-4 Trigger point injection technique. ), The number of trigger points injected at each session varies, as does the volume of solution injected at each trigger point and in total. However, these injections are probably best performed by physicians with postgraduate education in musculoskeletal anatomy, and a greater understanding of orthopedic and neurologic disorders. aka "trigger thumb injection", "trigger digit injection" Indications. Trigger point injections cause less soreness than dry-needling techniques. Capillary hemorrhage augments postinjection soreness and leads to unsightly ecchymosis.10 Patients should refrain from daily aspirin dosing for at least three days before injection to avoid increased bleeding. 2007 Mar;15(3):166-71. doi: 10.5435/00124635-200703000-00006. Bookshelf 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. Copyright 2002 by the American Academy of Family Physicians. Federal government websites often end in .gov or .mil. 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 set of trigger point injections means injections in several trigger points in one sitting. Copyright 2002 by the American Academy of Family Physicians. Therapeutic responses to corticosteroid injections are variable.4 The patient's response to previous injection is important in deciding whether and when to proceed with reinjection. Trigger points are first located by manual palpation with a variety of techniques (Figure 24-3). One-month outcomes were . Multiple insertions in different directions from the subcutaneous layer were fast in and fast out to probe for latent trigger points. Eighty-four patients were enrolled in a prospective randomized controlled trial comparing dexamethasone and triamcinolone injection for idiopathic trigger finger. Endogenous opioid release may play a role in TPIs. Figure 24-1 A central trigger point (TrP) located within a taut band of muscle. Always consult your healthcare provider to ensure the information displayed on this page applies to your personal circumstances. 2008 Jan;33(1):40-8. doi: 10.1016/j.jhsa.2007.10.009. Trigger points are defined as firm, hyperirritable loci of muscle tissue located within a taut band in which external pressure can cause an involuntary local twitch response termed a jump sign, which in turn provokes referred pain to distant structures. Tender points, by comparison, are associated with pain at the site of palpation only, are not associated with referred pain, and occur in the insertion zone of muscles, not in taut bands in the muscle belly.8 Patients with fibromyalgia have tender points by definition. Warnings and Interactions. Plast Surg (Oakv). The physiology of trigger points themselves is controversial, and therefore the mechanism of action through which injections aimed at trigger points may relieve pain is unknown. Postinjection soreness, a different entity than myofascial pain, often developed, especially after use of the dry needling technique.17 These results support the opinion of most researchers that the critical therapeutic factor in both dry needling and injection is mechanical disruption by the needle.1,10. Physical examination is extremely helpful in ascertaining the diagnosis. Prepare the area with an alcohol or povidone-iodine (Betadine) wipe. 12 None of these models have been accepted as the gold standard but they can be used to assess severity and assist in selecting the appropriate referral and treatment options. Choice of Corticosteroid Solution and Outcome After Injection for Trigger Finger. Trigger points may also manifest as tension headache, tinnitus, temporomandibular joint pain, decreased range of motion in the legs, and low back pain. The anesthetic provides early relief of symptoms and helps confirm the diagnosis. Sometimes it is not safe to use certain medications at the same time. Periarticular calcifications are described in the literature, but they are rare. Thermographic imaging evaluation has previously demonstrated elevated temperatures in the referral pain pattern of trigger points, suggesting increased local heat production from increased metabolism or neural activity. Follow the steps for site preparation. 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. 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. Trigger point injections are used to treat chronic pain in the: Lower back Neck Arms Legs Chronic pain in the areas mentioned above is typically associated with: Poor posture Injury to the muscle Poor mechanics that lead to stress of the muscle Joint disorders Written by Cerner Multum. Trigger points are first located by manual palpation with a variety of techniques (Figure 24-3). Identification of trigger points is required before performing these injections and is generally performed with a thorough manual and orthopedic examination.
