Sports-related and other soft-tissue injuries, tendinitis, bursitis, and occupation-related syndromes.

In this review, four areas are discussed: fluoroquinolone-induced tendinitis, volar flexor tenosynovitis (trigger finger), Achilles tendon lesions, and occupational medicine issues. The relationship of fluoroquinolone treatment to musculoskeletal lesions, especially Achilles tendinitis and tear, is most intriguing. The steady increase in reports of the association cannot be ignored. Although Achilles tendinitis and rupture have comprised the most frequently seen lesions, articles on additional sites of involvement, such as in lateral epicondylitis and De Quervain's tenosynovitis, are reviewed. Volar flexor tenosynovitis and trigger finger are among the most common musculoskeletal problems, and additional studies support the success of corticosteroid injections. Although the value of injections was reported well over 25 years ago, surgery is still unfortunately the first-choice treatment of some physicians. We review three studies on Achilles tendinopathy. In one of the reports, diagnostic ultrasonography is again demonstrated to be of value in assessing tendon lesions. The push to use the term tendinosis rather than tendinitis continues as a result of histologic studies of tendinitis that lack the usual findings of inflammation. However, the presence or absence of chemical inflammation is yet to be ascertained. We review an article that fails to show that work activities are the sole cause of such musculoskeletal syndromes as cumulative trauma or repetitive use. Further studies are needed in the area of work-related upper extremity disorders.
