The purpose was to investigate the efficacy of several diagnostic methods to detect superior labrum injuries in throwing shoulder. Fifty-four throwing athletes, who underwent arthroscopic surgery, were prospectively studied. There were superior labrum injuries in twenty-four cases and loose attachment of the superior labrum in six. The efficacy of preoperative diagnostic methods were investigated comparing them with arthroscopic findings of superior labrum injuries. The forced shoulder abduction and elbow flexion test (forced abduction test) was diagnosed as positive, when pain at the postero-superior aspect of the shoulder in forced maximal abduction was reduced or diminished in elbow flexion. The most useful test to detect superior labrum injuries was the forced abduction test, and the sensitivity, specificity, and accuracy was 73%,69%, and 70%, respectively. Loose attachment of the superior labrum significantly increased false positive rate of this method. Forced abduction tests were simple and effective for diagnosis of superior labrum injuries in throwing shoulders.

[Purpose] To clarify the diagnostic value of load and shift test (LST) for the assessment of glenohemeral joint laxity compared with examination under anesthesia (EUA).[Material and Method] We retrospectively reviewed the healthy-side shoulders of 100 patients (65males,35 females) who underwent surgical treatment of their opposite side. Their mean age was 27.5years. We examined the anterior and posterior laxity at 30° and 90° of abduction, and inferior laxity in neutral rotation with the arm at the side. The anterior or posterior laxity was graded into three degrees (-, +, + +), and the inferior laxity was graded into two degrees (sulcus sign -, +). We detrmined the joint laxity positive when the laxity was graded + or + +. We calculated the sensitivity, the specificity and the accuracy of the LST based on the results of the EUA. In addition, when a joint laxity existed at the anterior and posterior transelation on LST, we assessed the discrimination of the grade of the laxity on LST based on the results of the EUA.[Results]Sensitivity, specificity and accuracy of LST were as follows: inferior; 50.0%,96.0%,98.0%, anterior at 30°of abduction; 45.0%,96.3%,86.0%, anterior at 90°of abduction; 54.2%,100%,78.0%, posterior at 30°of abduction; 36.4%,92.9%,68.0%, posterior at 90°of abduction; 56.0%,88.9%,71.0%, respectively. The discrimination of the grade of laxity: anterior at 30°of abduction; 100%, anterior at 90°of abduction; 84.6%, posterior at 30° of abduction; 87.5%, posterior at 90°of abduction; 77.4%.[Conclusion]LST was not sensitive but a specific examination compaired with EUA fbr shoulder joint laxity. Moreover, LST was excellent for the discriminating the gradeof the laxity.
