Abstract
AIM: Up to now ESWT is not a standard therapeutic technique in orthopaedics. The mechanisms of the induced analgesic effect or the mechanism of shock-waves in bony defects are still unknown. By metaanalysis successrates and indications for ESWT are worked out as well as adequate impulse- and energyrates according to actual state of knowledge. Aim of this study is to rate the published cases. METHOD: 105 papers referring to ESWT of the locomotor system are rated. Validation was performed for each paper according to the international accepted system of the American Association of Spine Surgery in Type A-E. Advise for therapy is taken only from high quality publications of Type A and B. This advise should regard scientific as well as economic aspects. RESULTS: 4825 cases from 55 publications and abstracts that underwent ESWT were evaluated. 24 papers with 1585 cases (33%) live up to the standards of a scientific investigation. Numerous studies exist about therapy of calcifying tendinitis, epicondylitis humeri radialis, painful heel, pseudarthrosis and other enthesiopathies. Especially the studies concerning pseudarthosis and other enthesiopathies do hardly live up to scientific standards. In calcifying tendinitis and painful heel ESWT achieves nearly the same results than the established methods. No serious complications were observed. Because of the high complication rate in operative treatment of heel spur ESWT seems to be justifiable. The techniques of ESWT, energy density levels, impulse rates and complications will be described. CONCLUSION: The advantages of ESWT are non-invasiveness and low rate of complications. Primary aim should be to evaluate adequate energy density levels and impulse rates for specific groups of indications using high quality studies according to evidence-based-medicine. Long term results need to be awaited to be able to compare ESWT with established methods. Recent inflationary use of ESWT especially in outpatient departments has no scientific indication in numerous cases as conservative methods are not used consequently.
