[Exact method for the measurement of the rotation of the humerus head in the shoulder joint using computed tomography].
An exact method of measuring the degree of inward-and outward rotation in the humero-scapular joint is demonstrated. The advantage of the use of computed tomography as compared with the clinical method of measurement is the accurate differentiation of the mobility of the individual parts of the arm's mobile elements with respect to the trunk and the documentation of the result. For inward rotation we have measured a mean value of 38 degrees on the right side and of 37 degrees on the left; the corresponding values for outward rotation were 37 and 41 degrees. In eleven patients who had undergone Bankart's operation we found the outward rotation of the arm in the shoulder joint decreased to a mean value of 15 degrees.
