title: [Distribution pattern of subchondral mineralization in the glenoid cavity in normal subjects, athletes and patients].
abstract: To get information on the stresses acting on the shoulder joint, the distribution of subchondral mineralisation was examined by means of CT-Osteo-absorptiometry in the glenoid cavity in healthy people, athletes and patients. In young persons two density maxima are found ventrally and dorsally older persons, however, show a centrally located maximum which suggests a different joint mechanics in different ages depending on the decreasing physiological incongruence. In gymnasts the overall mineralisation is significantly higher, maxima are found centrally or shifted dorsally. In patients with recurrent dislocation of the shoulder or instability the zone of highest density is shifted to the edges of the glenoid cavity indicating that the prevailing position of the resultant force is excentric. By means of CT-Osteo-absorptiometry these individual patterns of mineralisation can be displayed in the living and can give information on the individual mechanical situation ("loading history") of a joint.
