A short-acting solution, such as dexamethasone sodium phosphate (Decadron), is less irritating and less likely to cause a postinjection flare than a long-acting dexamethasone suspension. Appropriate timing can minimize complications and allow a clear diagnosis or therapeutic response. A needle with a smaller gauge may also be deflected away from a very taut muscular band, thus preventing penetration of the trigger point. 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. 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.
