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.
为了获取作用于肩关节的应力信息，通过CT骨吸收测定法对健康人、运动员和患者的关节盂内软骨下矿化分布进行了检查。在年轻人中，在腹侧和背侧发现两个密度最大值；然而，在老年人中，最大值位于中心，这表明不同年龄的关节力学不同，这取决于生理上不一致性的降低。在体操运动员中，整体矿化明显更高，最大值位于中心或向背侧偏移。在患有复发性肩关节脱位或不稳定的患者中，最高密度区域转移到关节盂边缘，表明合力的主要位置是偏心的。通过CT骨吸收测定法，可以在活体中显示这些个体矿化模式，并可以提供有关关节个体力学情况（“负荷历史”）的信息。
