title: [Significance of calcium deposit elimination in tendinosis calcarea of the shoulder].
abstract: OBJECTIVE
  To evaluate the effect of complete elimination of the calcific deposit on the clinical outcome in patients with a recalcitrant calcifying tendinitis of the shoulder.
  
  
  METHODS
  50 patients with a chronic calcifying tendinitis of the shoulder (Type Gärtner I or II) underwent a single application of extracorporeal shock waves (3000 impulses, energy flux density 0.60 mJ/mm2). After one year 45 patients were evaluated radiologically and clinically.
  
  
  RESULTS
  Radiologically a complete absorption of the calcific deposit was observed in 21 patients (47%). In 9 patients there was no radiological change. The radiological success was closely related to the radiomorphology of the deposit. 18 out of 27 good or excellent results were accompanied by a complete disintegration of the deposit. We calculated a significant dependency between complete disintegration of the deposit and a good/excellent clinical result (p = 0.0002). Patients with a completely disintegrated deposit had significantly better scores than those with a partial disintegration of the calcium (p = 0.02), and than those with no radiomorphological changes (p = 0.0003). Spearman's correlation coefficient was 0.6.
  
  
  CONCLUSIONS
  Elimination of the deposit is paramount for a good clinical outcome and should be the main goal for any treatment.
