<Purpose> The purpose of this study was to investigate the strength of the glenoid labrum and capsule.<br><Materials and method> 15 shoulders of fresh cadavers were used for this study.6 of them were the right side and the rest of the 9 were the left side. Their ages ranged from fifty-five to eightyeight years. There were 6 males and 3 females. We determined the anterior, inferior and posterior portion of the labrum and capsule as the 3,6 and 9 o'clock position, respectively. The labrum and capsle were cut in 5mm width pieces. After fixing the glenoid, each respective piece of labrum and capsule was strained. We measured the applied force which detached the labrum from the glenoid.<br><Results> The 4 o'clock position was comparatively weaker than any other position, irrespective of the age or sex of the cadaver.<br><Conclusion> We conclude that the anterior-inferior portion of the glenoid is weaker than any other portion.
