Evidence-based soft tissue rheumatology: epicondylitis and hand stenosing tendinopathy.

Lateral and medial epicondylitis represent overuse tendinopathies of wrist extensor and wrist flexor muscles, respectively. In lateral epicondylitis, a short-term therapeutic efficacy of glucocorticoid injection and limited evidence on the efficacy of acupuncture has been shown. De Quervain tendinopathy is caused by tendinous impingement by a thickened retinaculum. There is limited evidence on the efficacy of glucocorticoid injection in this condition.Trigger finger usually results from tendon entrapment beneath a thickened A1 flexor pulley. An association with hand tool use and diabetes has been shown in this condition, and there is evidence on the therapeutic efficacy of glucocorticoid injection. No other therapeutic modality has shown efficacy or has been assessed in a placebo-controlled clinical trial in these conditions.It can be concluded that epicondylitis and stenosing tendinopathy are readily diagnosed, and most patients recover with current therapies. However, still unsolved issues preclude a purely evidence-based approach to these entities.
