The next step is to expose the joint capsule anteriorly by cutting the tendon of
the subscapularis muscle and reflecting it laterally being careful not to open the
joint capsule as shown the video.
As you reflect the subscapularis tendon, be careful not to cut the
tendon of the long of biceps brachii
where it pierces the capsule and is held in the intertubercular
groove by the transverse ligament of the humerus.
Now, pull out the cut ends of the tendons of the rotator cuff muscles demonstrates how
they form a "cuff" around the joint as seen in this dissection,
which shows the teres minor m., infraspinatus m., supraspinatus m., subscapularis m.,
and the coracoacromial ligament.
