title: Extracorporeal shock wave therapy in orthopedics. Assessment of an emerging health technology.
abstract: OBJECTIVE
  Extracorporeal shock wave therapy (ESWT) as an emerging technology in orthopedics has been assessed in Austria with the objective to establish a scientific basis for pending and pressing health policy decisions. Despite encouraging results within some indications and the promising prospect of a noninvasive treatment for some orthopedic diseases, it seemed crucial to assess this new field of application in the light of evidence-based standards, without forgetting the reality of healthcare decisions. This article presents the results of the above mentioned assessment in the context of the policy-making process in Germany, Austria, and Switzerland.
  
  
  METHODS
  The study is based on an overview of the already existing reviews on the effectiveness of ESWT as carried out by different actors (health insurances and orthopedists), and on an overview of additional literature covering all relevant aspects (mode of action, recommendations, economic estimates). Orthopedic societies, several institutions involved in health technology assessment, and health insurance agencies were contacted in search of further relevant literature, ongoing studies, and assessments.
  
  
  RESULTS
  Until now, clear evidence has not been available on the effectiveness of ESWT in four currently recommended indications (tendinosis calcarea of the shoulder, epicondylopathia humeri radialis, calcaneal spur, and pseudarthrosis), although a substantial body of literature has been produced. Despite encouraging results in some indications, the lack of coherent therapy schemes and the poor quality in the design of clinical studies has been serious enough to hinder the drawing of reasonable conclusions.
  
  
  CONCLUSIONS
  Due to the rapid diffusion of ESWT and the pressure on reimbursement agencies to prove the ineffectiveness of ESWT, the policy option of a pragmatic approach is recommended to control the diffusion of an uncertain health technology, alongside active research that would allow a more comprehensive appraisal of this potentially interesting treatment strategy in orthopedics.
