[Roentgen morphometry of the shoulder in diseased rotator cuff. Value of plain roentgen examination in comparison with arthroscopy].

A comparison between the pathomorphological substrate and the X-ray morphometry of the shoulder joint was made with 482 arthroscopically treated patients. Radiological parameters and indices for the prediction of the development of the impingement-syndrome were developed from this comparison. With these parameters and indices is it possible to predict the pathomorphological substrate and to differentiate between subacromial and coracoidal impingement.
