Background: More Recent studies showed that, the proximal attachment of long head of biceps brachii has dual attachment i.e. to the supraglenoid tubercle of the scapula and glenoid labrum at variable extent. The long head of biceps brachii may be a cause of shoulder pain as an isolated tendonitis of biceps brachii or other pathologies of the shoulder.
Objectives: To define the dual attachment and extent of the labral attachment of long head of biceps brachii anteriorly and posteriorly by gross examination..
Materials and Methods: We studied 189 (Right- 101; Left- 88) cadaveric shoulder joints of unknown sex and age. Careful dissection was carried out of each specimen to see the proximal attachment of long head of biceps by gross examination. The anterior and posterior labral margins were examined carefully to see the extent of labral attachment of long head of biceps brachii tendon (LHBBT). The glenoid cavity was divided into upper, middle and lower parts.
Results and Conclusion: Tendon of long head of biceps brachii was attached to posterior labrum only in 5 cases. In remaining 184 specimens it was attached to supraglenoid tubercle and glenoid labrum anteriorly and posteriorly at variable extent with strong posterior orientation. This knowledge is helpful in not only in evaluation, diagnosis and treating labral pathology of shoulder joint but also for the open glenohumeral surgeries.
