The main features of the upper end of the humerus are the
presence of greater and lesser tubercles, with the bicipital groove intervening
between these tubercles. The bicipital groove, also known as the
intertubercular sulcus, houses the tendon of the long head of the biceps
brachii muscle. As per the classical description, the bicipital groove is
bridged by the transverse humeral ligament. But literature search including
histological studies revealed that tissue overlying the bicipital groove is not
a ligament; instead, the tissue covering the bicipital groove consists of
tendinous fibres from the subscapularis and supraspinatus muscles. Thus, the
aim of this chapter is to establish whether the tissue bridging the bicipital
groove is ligament or tendinous fibres from various muscles constituting the
rotator cuff. In this chapter, data from various radiological studies
consisting of MRI, including dissection and histological studies, have been
expounded to validate the presence of tissue over the bicipital groove, i.e.
whether it is ligament or tendinous fibers.
