ABSTRACT:

Objectives: The objective of this study is to identify and categorize the variations in origin of tendon of long head of biceps brachii (LHBB).

Methods: The study was carried out on 60 upper limbs of cadaver in the Anatomy department, SMBT IMS & RC, Nashik, India. After exposing the glenoid fossa, we find out the origin of tendon of LHBB from the supraglenoid tubercle and the adjoining glenoid labrum. Labrum is divided into anterior and posterior part.

Results: In 11 specimens origin of LHBB was seen from supraglenoid tubercle only, Other specimens has dual origin of LHBB along with Glenoid labrum. We classified it according to Vangsness et al. Type I: The labral attachment is entirely posterior, with no contribution to anterior labrum, seen in 31 specimens. Type II: The tendon attached mainly to the posterior part of the Glenoid labrum with also extended up to the anterior labrum, seen in 16 specimens. Type III: There are equal contribution to both the anterior and posterior parts of the labrum, found in only 2 specimens. Type IV: Most of the labral contribution is anterior, with a small contribution to the posterior labrum. No specimen found.

Conclusion: Anatomical variation in origin of LHBB help us to explain the correlation of recurrent shoulder dislocation and labral detachment.This knowledge is necessary to avoid errors in shoulder arthroscopy, radiological investigations and surgical repair.

Key words: Tendon of long head of Biceps Brachii (LHBB), Origin of long head of Biceps Brachii (LHBB), Stability of shoulder joint, Glenoid Labrum.
