title: [Therapy relevant imaging in modern surgical treatment of arthrosis of the shoulder :  Interesting facts for orthopedic surgeons].
abstract: OBJECTIVE
  Imaging for shoulder surgery varies a lot nowadays. Advantages and disadvantages of possible imaging methods according to the pathology and treatment options are described.
  
  
  METHODS
  Digital projection radiography in 3 planes, ultrasonography, MRI, CT scanning and scintigrams.
  
  
  METHODS
  Special axial view to visualize the glenoid situation, as well as 3-D CT scanning for larger defects and classification.
  
  
  METHODS
  Imaging of the glenoid situation, the version and erosion in axial view x-ray is mandatory to plan and control glenoid replacement.
  
  
  RESULTS
  Useful application of imaging methods for the daily routine of orthopedic surgeons.
  
  
  CONCLUSIONS
  Digital 3 plane x-ray imaging in arthroplasty surgery is the minimum requirement. For rotator cuff lesions ultrasonography is good. In order to gain information on fatty infiltration of rotator muscles MRI is needed as well as for intra-articular lesions. For bony defects CT and reconstruction 3-D are recommended.
