| Abstract: | An osteometry of instable glenohumeral-joints was done by computerized tomography. In comparison of type and direction of the instability, a marked retroversion of the glenoid was found in posterior luxation, not only in the instable, but also in the contralateral side. There seems no statistical prove of an influence by a changed radius or width of the humerus-head nor by a reduced retrotorsion of the humerus. Posttraumatic disorders like HILL-SACHS-lesions or BANKART-lesions are more easily detected by computerized tomography than by conventional radiography. |
