                Cohort study (Diagnosis); Level of evidence, 2.
                A total of 325 consecutive patients who were seen for shoulder pain underwent a standardized clinical testing battery. Six clinical tests that have been previously reported in the literature (Yergason's, Speed's, bear hug, belly press, O'Brien's, and anterior slide) and 2 new examination tests (upper cut and modified dynamic labral shear) were performed. Clinical examination findings were correlated with findings in those who came to surgery (101 patients). Sensitivity, specificity, accuracy, positive/negative predictive value, and positive/negative likelihood ratio were calculated for each test. A binary logistic regression analysis was used to determine which tests produced the most significant findings.
                For biceps disease, the bear hug and upper cut were most sensitive (0.79 and 0.73, respectively), whereas the belly press and Speed's test were most specific (0.85 and 0.81, respectively). The upper cut was most accurate (0.77) and produced the highest positive likelihood ratio (3.38). For labral injury, the modified dynamic labral shear demonstrated sensitivity of 0.72, specificity of 0.98, accuracy of 0.84, and a positive likelihood ratio of 31.57. A binary logistic regression analysis revealed that the combination of the upper cut and Speed's tests were significantly better at detecting biceps lesions (P = .021, R(2) = .400) than other tests, whereas labral lesions were best identified by combination of the modified dynamic labral shear and O'Brien's maneuvers (P = .045, R(2) = .641).
                The new tests are helpful additions to the clinical examination for shoulder injury. The modified dynamic labral shear test demonstrates high scores for clinical utility and exhibits a high likelihood ratio, indicating a significant probability of affecting the clinical decision, which should moderately or significantly improve the diagnostic conclusion and allow the clinician to be more efficient in making an accurate diagnosis. Many types of physical examinations have been used to diagnose superior labrum anterior and posterior lesions; no decisive clinical test is available for confirming the diagnosis.
                A selection from 10 well-established physical tests, alone or in combination, can be used to differentiate lesions with biceps anchor detachment from those with an intact biceps anchor with arthroscopic correlation.
                Case control study (diagnosis); Level of evidence, 3.
                Among 297 patients who underwent shoulder arthroscopy between January 2004 and July 2005, 146 patients were enrolled in the study as a type II superior labrum anterior and posterior lesion group and an age-matched control group. Sensitivity, specificity, and predictive values of each test and all possible combinations of 2 and 3 tests were analyzed. The same procedures were repeated in patients younger than and older than 40 years.
                The sensitivities of the Whipple, O'Brien, apprehension, and compression-rotation tests and the specificities of the Yergason, biceps load II, and Kibler tests were relatively high. No single physical examination was found to be simultaneously highly sensitive and specific for the diagnosis of a type II superior labrum anterior and posterior lesion. When 2 of the 3 relatively sensitive tests (O'Brien, apprehension, or compression-rotation test) were combined with 1 of the 3 relatively specific tests (Speed, Yergason, or biceps load II test), sensitivity and specificity reached approximately 70% and 95%, respectively. Similar trends were noted in the younger and older patient groups and in the isolated type II superior labrum anterior and posterior lesion group.
                The data suggest that some combinations of 2 relatively sensitive clinical tests and 1 relatively specific clinical test increase the diagnostic efficacy of superior labrum anterior and posterior lesions. Requiring 1 of the 3 chosen tests to be positive will result in a sensitivity of about 75%, whereas requiring all 3 to be positive will result in a specificity of about 90%. Even though there are several physical tests available for superior labrum anterior posterior lesions, there have been very few reports on their accuracy, and none can be regarded as completely predictive for the presence of a superior labrum anterior posterior lesion in the shoulder joint.
                This new clinical test is a useful and accurate technique for detecting superior labral tears in the shoulder joint.
                Cohort study (diagnosis); Level of evidence, 2.
                This test was conducted independently by 2 physicians before any other diagnostic evaluation. In all cases, the glenohumeral joint was investigated first, and the appropriate treatments were performed on the lesion. A protocol was established to evaluate the sensitivity, specificity, and positive and negative predictive values of this new clinical test. The reproducibility of this test was evaluated with a kappa coefficient.
                Sixty-one patients (61 shoulders) were examined with the passive compression test, and all underwent arthroscopic surgery. In 31 patients with a positive passive compression test result, 27 had a superior labrum anterior posterior lesion, and in 30 patients with a negative passive compression test result, 6 had a superior labrum anterior posterior lesion. The sensitivity of the test was 81.8%, and the specificity was 85.7%. The positive predictive value was 87.1%, and the negative predictive value was 80.0%. The kappa coefficient was 0.771 between the 2 independent examiners (P< .01).
                The passive compression test is a useful and accurate technique for predicting superior labral tears of the shoulder joint. 32 consecutive patients suffering from chronic shoulder pain for more than 6 months after a single, nondislocating shoulder trauma were examined clinically and by special radiographs, dynamic sonography, MRI and arthroscopy. Typical complaints were pain during loading, especially during over the head activities. Symptoms of a "dead arm" and instability were also present. Patients with previous dislocations, traumas or radiographic signs of degenerative shoulder lesions were excluded. The patients had a decreased active range of motion and positive signs of apprehension and impingement, but only 4 had clinical signs of shoulder instability. Diagnostic evaluation identified labral tears, partial and total rotator cuff lesions with subacromial impingement and tendinitis of the biceps tendon. Surgery was performed in 24 patients, using capsulolabral and rotator cuff reconstruction, arthroscopic labral resection and open subacromial decompression. In conclusion, patients with chronic posttraumatic shoulder pain have intraarticular injuries, especially tears of the glenoid labrum. History, clinical findings, radiography and sonography are seldom diagnostic. MRI is valuable, particularly for identification of labral pathology, but arthroscopy appears necessary for a preoperative assessment. Labral tears and acromioclavicular joint abnormalities were differentiated on physical examination using a new diagnostic test. The standing patient forward flexed the arm to 90 degrees with the elbow in full extension and then adducted the arm 10 degrees to 15 degrees medial to the sagittal plane of the body and internally rotated it so that the thumb pointed downward. The examiner, standing behind the patient, applied a uniform downward force to the arm. With the arm in the same position, the palm was then fully supinated and the maneuver was repeated. The test was considered positive if pain was elicited during the first maneuver, and was reduced or eliminated with the second. Pain localized to the acromioclavicular joint or "on top" was diagnostic of acromioclavicular joint abnormality, whereas pain or painful clicking described as "inside" the shoulder was considered indicative of labral abnormality. A prospective study was performed on 318 patients to determine the sensitivity, specificity, and positive and negative predictive values of the test. Fifty-three of 56 patients whose preoperative examinations indicated a labral tear had confirmed labral tears that were repaired at surgery. Fifty-five of 62 patients who had pain in the acromioclavicular joint and whose preoperative examinations indicated abnormalities in the joint had positive clinical, operative, or radiographic evidence of acromioclavicular injury. There were no false-negative results in either group. With the increasing use of shoulder arthroscopy, diagnosis of glenoid labral lesions has become increasingly common. However, a physical examination maneuver that would allow a definitive clinical diagnosis of a glenoid labral tear, and more specifically a SLAP lesion, has been elusive. This study correlated the results of commonly used examination maneuvers with findings at shoulder arthroscopy. The working hypothesis was that 7 commonly used clinical tests, alone or in logical combinations, would provide diagnoses with reliability greater than the accepted standards for magnetic resonance imaging arthrography; i.e., greater than 95% sensitivity and specificity.
                Consecutive sample, sensitivity-specificity study.
                Sixty shoulders undergoing arthroscopy for a variety of pathologies were examined before surgery. All subjects submitted to the Speed test, an anterior apprehension maneuver, Yergason test, O'Brien test, Jobe relocation test, the crank test, and a test for tenderness of the bicipital groove. The examination results were compared with surgical findings and analyzed for sensitivity and specificity in the diagnosis of SLAP lesions and other glenoid labral tears.
                The results of the O'Brien test (63% sensitive, 73% specific) and Jobe relocation test (44% sensitive, 87% specific) were statistically correlated with presence of a tear in the labrum and the apprehension test approached statistical significance. Performing all 3 tests and accepting a positive result for any of them increased the statistical value, although the sensitivity and specificity were still disappointingly low (72% and 73%, respectively). The other 4 tests were not found to be useful for labral tears, and none of the tests or combinations were statistically valid for specific detection of a SLAP lesion.
                Clinical testing is useful in strengthening a diagnosis of a glenoid labral lesion, but the sensitivity and specificity are relatively low. Thus a decision to proceed with surgery should not be based on clinical examination alone. The purpose of this report is to describe the biceps load test II for evaluating the superior labral anterior and posterior (SLAP) lesions.
                This is a double-blind study in consecutive data, which includes diagnostic accuracy of a test using sensitivity, specificity, and interexaminer reliability.
                In the supine position, the arm is elevated to 120 degrees and externally rotated to its maximal point, with the elbow in the 90 degrees flexion and the forearm in the supinated position. The patient is asked to flex the elbow while resisting the elbow flexion by the examiner. The test is considered positive if the patient complains of pain during the resisted elbow flexion. The test is negative if pain is not elicited or if the pre-existing pain during the elevation and external rotation of the arm is unchanged or diminished by the resisted elbow flexion. A prospective study was performed in 127 patients to evaluate the diagnostic accuracy for the biceps load test II. Two independent examiners were assigned to perform the new diagnostic test. The results of the tests were confirmed during the arthroscopic examination.
                A positive test result in 38 subjects correlated with a SLAP lesion in 35 patients and an intact biceps-superior labrum in 3 patients. A negative test result in 89 patients correlated with an intact superior labrum complex in 85 patients, whereas 4 patients with a negative test result had a type II SLAP lesion. The biceps load test II had a sensitivity of 89.7%, a specificity of 96.9%, a positive-predictive value of 92.1%, a negative-predictive value of 95.5%, and a kappa coefficient of 0.815. The abduction and external rotation of the shoulder during the test changes the relative direction of the biceps fiber in a position of oblique angle to the posterosuperior labrum. The resisted contraction of the biceps increases the pain generated on the superior labrum that is already peeled off the glenoid margin in the abducted and externally rotated position.
                The biceps load test II is an effective diagnostic test for SLAP lesions. Although our understanding of superior labral anterior posterior lesions has grown, the physical diagnosis remains imperfect.

                To determine the most effective provocative maneuver with which to diagnose superior labral anterior posterior lesions.
                A series of 132 consecutive patients scheduled to undergo diagnostic shoulder arthroscopy were examined preoperatively over a 6-month period, and the final diagnosis in each case was made arthroscopically. The following assessments were included: active compression (O'Brien), anterior slide, pain provocation, crank, Jobe relocation, Hawkins, Neer, Speed, and Yergason tests.
                The most sensitive diagnostic tools for type II superior labral lesions were the active compression, Hawkins, Speed, Neer, and Jobe relocation tests. When type I and type II lesions were combined, the results were similar. However, none of the sensitive tests were specific for either type I or type II lesions.
                The authors' results contradict the current literature regarding provocative testing for both stable and unstable superior labral lesions. There is no single maneuver that can accurately diagnose superior labral anterior posterior lesions; arthroscopy remains the standard by which to diagnose such lesions. Tears of the superior labrum of the shoulder, anterior to posterior, are difficult to diagnose clinically.
                We examined whether the crank or O'Brien tests were reliable tools for detecting glenoid labral tears.
                Nonrandomized prospective study.
                Results of diagnostic shoulder arthroscopy were compared with those of the preoperative tests and magnetic resonance imaging for 65 patients who had symptoms of shoulder pain.
                The crank test result was positive in 29 patients (45%), and the O'Brien test was positive in 41 patients (63%). The crank test had a positive predictive value of 41%, was 56% specific, 46% sensitive, and had a negative predictive value of 61%. The O'Brien test had a positive predictive value of 34%, was 31% specific, 54% sensitive, and had a negative predictive value of 50%. Magnetic resonance imaging had a positive predictive value of 63%, was 92% specific, 42% sensitive, and had a negative predictive value of 83%.
                The O'Brien and crank tests were not sensitive clinical indicators for detecting glenoid labral tears and other tears of the anterior and posterior labrum. Results were often falsely positive for patients with other shoulder conditions, including impingement or rotator cuff tears.
There is insufficient evidence upon which to base selection of physical tests for shoulder impingements, and local lesions of bursa, tendon or labrum that may accompany impingement, in primary care. The large body of literature revealed extreme diversity in the performance and interpretation of tests, which hinders synthesis of the evidence and/or clinical applicability.
