PMC The desensitization or antinociceptive effects by pressure, cold, heat, electricity, acupuncture, or chemical irritation relies on gate-control theory from Melzack.58,59 Local anesthetic also blocks nociceptors by reversible action on sodium channels. Table 210,18 outlines the necessary equipment for trigger-point injection. Not all possible interactions are listed here. A set of trigger point injections means injections in several trigger points in one sitting. Needle insertion was into the subcutaneous tissue adjacent to the trigger point at an angle of 50 to 70 degrees to the skin, aiming at the taut band.
Dexamethasone: Uses, Side Effects, Dosages, Precautions - Verywell Health A muscle fiber energy crisis was hypothesized to produce taut bands.
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.1038 Although this chapter focuses on TPIs for chronic low back pain (CLBP), trigger points may occur elsewhere in the body. The PubMed wordmark and PubMed logo are registered trademarks of the U.S. Department of Health and Human Services (HHS). Nonpharmacologic treatment modalities include acupuncture, osteopathic manual medicine techniques, massage, acupressure, ultrasonography, application of heat or ice, diathermy, transcutaneous electrical nerve stimulation, ethyl chloride Spray and Stretch technique, dry needling, and trigger-point injections with local anesthetic, saline, or steroid. For thick subcutaneous muscles such as the gluteus maximus or paraspinal muscles in persons who are not obese, a 21-gauge, 2.0-inch needle is usually necessary.10 A 21-gauge, 2.5-inch needle is required to reach the deepest muscles, such as the gluteus minimus and quadratus lumborum, and is available as a hypodermic needle. 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 needle should be long enough so that it never has to be inserted all the way to its hub, because the hub is the weakest part of the needle and breakage beneath the skin could occur.6, An injectable solution of 1 percent lidocaine or 1 percent procaine is usually used. Patients should be educated to look for signs of infection including erythema, warmth, or swelling at the site of injection, or systemic signs including fever and chills. Dexamethasone can affect growth in children. Each thrust coincided with the injection of 0.02 to 0.05mL of injectate, up to a total of 0.5 to 1mL in each trigger point. Various modalities, such as the Spray and Stretch technique, ultrasonography, manipulative therapy and injection, are used to inactivate trigger points. Twenty-five patients requested a second injection (10 triamcinolone arm, 15 dexamethasone arm), and 21 elected operative treatment (10 triamcinolone arm, 11 dexamethasone arm) during the study period. First popularized by Janet Travell, MD, muscle injections are a. The calcitonin gene-related peptide may be associated with this condition becoming chronic, as is hypothesized to occur in some patients with CLBP. However, insufficient training in trigger point examination likely impedes recognition of myofascial pain, and palpation generally has poor interrater reliability. This positioning may also help the patient to avoid injury if he or she has a vasovagal reaction.18, The choice of needle size depends on the location of the muscle being injected. Numbness from the anesthetic may last about an hour, and a bruise may form at the injection site but this is not common. Purpose: However, these injections are probably best performed by physicians with postgraduate education in musculoskeletal anatomy, and a greater understanding of orthopedic and neurologic disorders. Contraindications to trigger-point injection are listed in Table 310,18 and possible complications are outlined in Table 4. To avoid direct needle injury to articular cartilage or local nerves, attention should be paid to anatomic landmarks and depth of injection. To preserve autonomy, patients were permitted additional injections and operative treatment at any time. Drugs.com provides accurate and independent information on more than 24,000 prescription drugs, over-the-counter medicines and natural products. Patients report few systemic symptoms, and associated signs such as joint swelling and neurologic deficits are generally absent on physical examination.14, In the head and neck region, myofascial pain syndrome with trigger points can manifest as tension headache, tinnitus, temporomandibular joint pain, eye symptoms, and torticollis.15 Upper limb pain is often referred and pain in the shoulders may resemble visceral pain or mimic tendonitis and bursitis.5,16 In the lower extremities, trigger points may involve pain in the quadriceps and calf muscles and may lead to a limited range of motion in the knee and ankle. The agents differ according to potency (Table 3), solubility, and crystalline structure. Drug class: Glucocorticoids. Maillefert's review of epidural injections with dexamethasone, a nonparticulate steroid with theoretically shorter duration of action, still demonstrated profound decreases in serum ACTH and free cortisol levels on postinjection days 1 and 7, with normal ACTH levels returning on day 21. 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. Using analysis of prospective randomized study comparing transforaminal lumbar epidural injection with lumbar paraspinal trigger-point injection for treatment of patients with sciatica from herniated discs. FOIA
When clinicians were asked to examine patients with either myofascial pain, fibromyalgia, or healthy controls, the number of tender points identified was generally consistent.43 Even among experts in myofascial pain and fibromyalgia there was inconsistency in the number of taut bands, presence of referred pain, and local twitch responses reported.
Trigger Point Injection Article - StatPearls 1362-6. Repeated injections in a particular muscle are not recommended if two or three previous attempts have been unsuccessful. Cardone DA et al.
Trigger Point Injection Side Effects & Medications - MedicineNet A trigger point injection involves the injection of medication directly into the trigger point. Appropriate timing can minimize complications and allow a clear diagnosis or therapeutic response. Acetylcholine receptors are then up-regulated, resulting in more efficient binding, and producing taut bands. A third party should witness the patient's signing. Side Effects. Brand names: Decadron, De-Sone LA Alterations in taste have been reported for one to two days after steroid injection. Evidence-based reviews of joint and soft tissue injection procedures have found few studies that support or refute the efficacy of common joint interventions in medical practice.13 However, substantial practice-based experience supports the effectiveness of joint and soft tissue injection for many common problems. 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. TPIs usually require that the patient wear a medical gown and lie prone on a treatment table. Intrathecal solution and injection solution with or without methylparaben and or preservatives: 0.25%, 0.5%, 0.75% in 2, 10, 30, 50 mL. 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. It can take as long as 20 to 30 minutes following the injection for these symptoms to present. Low-solubility agents, favored for joint injection, should not be used for soft tissue injection because of the increased risk of surrounding tissue atrophy.

Sixty-seven patients completed the 6-week follow-up (35 triamcinolone arm, 32 dexamethasone arm), and 72 patients completed the 3-month follow-up (41 triamcinolone arm, 31 dexamethasone arm). Pneumothorax; avoid pneumothorax complications by never aiming a needle at an intercostal space. The dose of anesthetic varies from 0.25 mL for a flexor tendon sheath (trigger finger) to 5 to 8 mL for larger joints. Moreover, the inactivation of the trigger point restores mobility in the treated area. In some cases, these trigger points may originate from injury or damage to a specific joint in the neck (the facet joint). Trigger points are painful "knots" in your muscles that can be very sensitive to touch/pressure. Avoid drinking alcohol while you are taking dexamethasone.

History of pain, local and referred, will provide important clues to the underlying pathology. Description Your health care provider inserts a small needle and injects medicine into the painful and inflamed area. Live vaccines include measles, mumps, rubella (MMR), rotavirus, typhoid, yellow fever, varicella (chickenpox), and zoster (shingles).
Thus, these two pain syndromes may overlap in symptoms and be difficult to differentiate without a thorough examination by a skilled physician. 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. Version: 5.01. Pay attention to the depth of needle insertion to avoid needle trauma to articular cartilage. Re-evaluation of the injected areas may be necessary, but reinjection of the trigger points is not recommended until the postinjection soreness resolves, usually after three to four days. Dosage. They produce pain locally and in a referred pattern and often accompany chronic. Trigger point injection is one of many modalities utilized in the management of chronic pain. Trigger-point injection has been shown to be one of the most effective treatment modalities to inactivate trigger points and provide prompt relief of symptoms. To prevent complications, adhere to sterile technique for all joint injections; know the location of the needle and underlying anatomy; avoid neuromuscular bundles; avoid injecting corticosteroids into the skin and subcutaneous fat; and always aspirate before injecting to prevent intravascular injection. There were no significant differences between Disabilities of the Arm, Shoulder, and Hand scores at the 6-week follow-up and the 3-month follow-up. Copyright 1996-2023 Cerner Multum, Inc. However, its use is safer for both patient and physician than the original volatile vapor coolant, ethyl chloride. When possible, the patient should be placed in the supine position. A healthcare provider will give you this injection. Trigger points are discrete, focal, hyperirritable spots located in a taut band of skeletal muscle. 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. J Child Orthop. 1 Establishing a diagnosis of trigger points often includes a history of regional pain, Ann Rheum Dis.

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. 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. High doses or long-term use of steroid medicine can lead to thinning skin, easy bruising, changes in body fat (especially in your face, neck, back, and waist), increased acne or facial hair, menstrual problems, impotence, or loss of interest in sex. The commonly encountered locations of trigger points and their pain reference zones are consistent.8 Many of these sites and zones of referred pain have been illustrated in Figure 2.10. Care should be taken to avoid direct injection of tendons because of the danger of rupture. Avoid receiving a "live" vaccine, or you could develop a serious infection. The injections were made in the volunteers' upper trapezius muscles; there was a 15-minute interval between injections. Preservative free formulations should be used in caudal or epidural block. Comparison of Different Dosages and Volumes of Triamcinolone in the Treatment of Stenosing Tenosynovitis: A Prospective, Blinded, Randomized Trial. Acute trauma or repetitive microtrauma may lead to the development of stress on muscle fibers and the formation of trigger points. Clipboard, Search History, and several other advanced features are temporarily unavailable. Any physician familiar with the localization of trigger points and the use of therapeutic musculoskeletal injections may perform TPIs. Several other substances, including diclofenac (Voltaren), botulinum toxin type A (Botox), and corticosteroids, have been used in trigger-point injections. Trigger point injection, which is commonly used to treat other pain conditions, has been shown to improve symptoms in women with chronic pelvic pain, with efficacy similar to that of physical.

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. Animal and human models suggest that the local twitch responses and referred pain associated with trigger points are related to spinal cord reflexes. Many researchers agree that acute trauma or repetitive microtrauma may lead to the development of a trigger point. A trigger point injection can help soothe myofascial pain, especially in your neck, shoulder, arms, legs and lower back. Increased bleeding tendencies should be explored before injection. On rare occasions, patients exhibit signs of anesthetic toxicity, including. Treating pain with a multimodal approach is paramount in providing safe and effective results for patients. DAVID J.

Tell your doctor about any such situation that affects you. Additionally, local circulation was thought to be compromised, thus reducing available oxygen and nutrient supply to the affected area, impairing the healing process. Injection techniques are helpful for diagnosis and therapy in a wide variety of musculoskeletal conditions.
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.65 Gerwin and colleagues recently expanded on Simons integrated hypothesis for trigger point formation and proposed a complex molecular pathway whereby unconditioned muscle undergoes eccentric exercise or trauma, which results in muscle fiber injury and hypoperfusion from capillary constriction.66 Sympathetic nervous system activation further enhances this constriction and creates a hypoxic and acidic environment, facilitating the release of calcitonin gene-related peptide and acetylcholine. Patients may have regional, persistent pain resulting in a decreased range of motion in the affected muscles. Bethesda, MD 20894, Web Policies This list may not describe all possible side effects. They produce pain locally and in a referred pattern and often accompany chronic musculoskeletal disorders.
