Comparison of the diagnostic value of four tests for superior labrum anterior and posterior lesions of the shoulde

To compare the diagnostic value of four signs for superior labrum anterior and posterior (SLAP) lesions of the shoulder.Methods The physical examination was performed randomly on 81 cases with abnormalities of the shoulder.There were four tests,including Kibler anterior sliding test,Liu crank test,O’Brien active compression test and Kim biceps load test Ⅱ.The arthroscopic examination were also performed.The result of the arthroscopic examination was considered as a golden standard,so that we could estimate the diagnosis value of the four tests according to the method of evaluation of diagnosis test on clinical epidemiology,their sensitivity,specificity,positive and negative predictive value,accuracy.Results There were 21 cases diagnosed as SLAP lesions by arthroscopy.The diagnosis value of Kim biceps load test Ⅱ was the highest among the four tests,in which 19 of true positive,59 of true negative,1 of false positive,only 2 of false negative cases;while the sensitivity was 90.48%,specificity was 98.33%,positive predictive value was 95.00%,negative predictive value was 96.72%,and accuracy was 96.30%.However the sensitivity,specificity,positive predicitive value,negative predictive vale and accuracy of Kibler anterior sliding test were 76.19%,96.67%,88.89%,92.06%,91.33%;and those of Liu crank test were 85.71%,93.33%,81.82%,94.92%,91.35%;those of O’Brien active compression test were 80.95%,91.66%,77.27%,93.22%,88.89%.Conclusion Kim Biceps load test Ⅱ may be the best for clinical diagnosis of SLAP lesions of the shoulder.9 refs,4 figs,2 tabs.

Management of proximal biceps tendon pathology

The long head of the biceps tendon is widely recognized as an important pain generator,especially in anterior shoulder pain and dysfunction with athletes and working individuals.The purpose of this review is to provide a current understanding of the long head of the biceps tendon anatomy and its surrounding structures,function,and relevant clinical information such as evaluation,treatment options,and complications in hopes of helping orthopaedic surgeons counsel their patients.An understanding of the long head of the biceps tendon anatomy and its surrounding structures is helpful to determine normal function as well as pathologic injuries that stem proximally.The biceps-labral complex has been identified and broken down into different regions that can further enhance a physician’s knowledge of common anterior shoulder pain etiologies.Although various physical examination maneuvers exist meant to localize the anterior shoulder pain,the lack of specificity requires orthopaedic surgeons to rely on patient history,advanced imaging,and diagnostic injections in order to determine the patient’s next steps.Nonsurgical treatment options such as anti-inflammatory medications,physical therapy,and ultrasound-guided corticosteroid injections should be utilized before entertaining surgical treatment options.If surgery is needed,the three options include biceps tenotomy,biceps tenodesis,or superior labrum anterior to posterior repair.Specifically for biceps tenodesis,recent studies have analyzed open vs arthroscopic techniques,the ideal location of tenodesis with intra-articular,suprapectoral,subpectoral,extra-articular top of groove,and extra-articular bottom of groove approaches,and the best method of fixation using interference screws,suture anchors,or cortical buttons.Orthopaedic surgeons should be aware of the complications of each procedure and respond accordingly for each patient.Once treated,patients often have good to excellent clinical outcomes and low rates of complications.
