[Therapy relevant imaging in modern surgical treatment of arthrosis of the shoulder : Interesting facts for orthopedic surgeons].

CLINICAL/METHODICAL ISSUE: Imaging for shoulder surgery varies a lot nowadays. Advantages and disadvantages of possible imaging methods according to the pathology and treatment options are described.

STANDARD RADIOLOGICAL METHODS

Digital projection radiography in 3 planes, ultrasonography, MRI, CT scanning and scintigrams.

METHODICAL INNOVATIONS

Special axial view to visualize the glenoid situation, as well as 3-D CT scanning for larger defects and classification.

PERFORMANCE

Imaging of the glenoid situation, the version and erosion in axial view x-ray is mandatory to plan and control glenoid replacement.

ACHIEVEMENTS

Useful application of imaging methods for the daily routine of orthopedic surgeons.

PRACTICAL RECOMMENDATIONS

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.
