Inflammation of periarticular soft-tissue structures such as tendons, tendon sheaths, entheses, bursae, ligaments and fasciae are the hallmark of many inflammatory rheumatic diseases, but inflammation - or rather irritation - of these structures also occurs in the absence of an underlying rheumatic disease. In both these primary and secondary soft-tissue lesions, local glucocorticoid injection often is beneficial, although evidence in literature is limited. This chapter reviews local injection therapy for these lesions and for nerve compression syndromes.
